技术领域technical field

本公开涉及管路技术领域，具体地，涉及一种管路排气系统、热管理系统及车辆。The present disclosure relates to the technical field of pipelines, in particular, to a pipeline exhaust system, a heat management system and a vehicle.

背景技术Background technique

现阶段，大多数的管路系统(例如，动力车辆的热管理管路系统)无法实现有效排气，尤其是在更换循环液时，无法进行有效的排气，导致循环液无法灌满。由于管路系统的管道复杂，尤其在拐角点和弯曲管道顶部处都容易出现气泡，而这些气泡多了会严重影响到管路性能。现阶段，主要通过以下两种方式实现管路系统排气：(1)使用外部真空加注机，通过抽离管路系统中的气体，造成内部气压小，在灌注循环液时，易于把管道灌满循环液，规避了排气问题；(2)外接排气工装，通过串联一个水箱和水泵的方式把气体排出。但这两种方式均存在无法实现自动排气、外接设备成本高昂、维修操作不便等问题。At present, most pipeline systems (for example, thermal management pipeline systems of power vehicles) cannot achieve effective exhaust, especially when changing the circulating fluid, which leads to the inability to fill the circulating fluid. Due to the complexity of the pipeline system, air bubbles are prone to appear especially at the corners and the top of the curved pipe, and these bubbles will seriously affect the performance of the pipeline. At this stage, the exhaust of the pipeline system is mainly achieved through the following two methods: (1) Use an external vacuum filling machine to remove the gas in the pipeline system, resulting in low internal air pressure. It is filled with circulating fluid to avoid the exhaust problem; (2) External exhaust tooling is used to discharge the gas by connecting a water tank and a water pump in series. However, these two methods have problems such as the inability to realize automatic exhaust, the high cost of external equipment, and the inconvenience of maintenance and operation.

(3)调节阀32接收第一预设排气信号，并基于第一预设排气信号关闭。(3) The regulatingvalve 32 receives the first preset exhaust signal and closes based on the first preset exhaust signal.

在本公开中，管路处于正常循环状态时，调节阀的开度为100％，在其满足初始排气条件时，调节阀32关闭，由于水泵31处于工作状态，因此，第一管路中循环液的液压快速增大，第二管路中循环液的液压迅速减小，导致调节阀32两端循环液的液压不一致。In this disclosure, when the pipeline is in a normal circulation state, the opening of the regulating valve is 100%. When it meets the initial exhaust condition, the regulatingvalve 32 is closed. Since thewater pump 31 is in a working state, the first pipeline The hydraulic pressure of the circulating fluid increases rapidly, and the hydraulic pressure of the circulating fluid in the second pipeline decreases rapidly, resulting in inconsistent hydraulic pressures of the circulating fluid at both ends of the regulatingvalve 32 .

(4)控制模块1检测管路是否满足第一预设条件，并在检测到管路满足第一预设条件时，发送第二预设排气信号至调节阀32。(4) Thecontrol module 1 detects whether the pipeline satisfies the first preset condition, and sends a second preset exhaust signal to the regulatingvalve 32 when it detects that the pipeline satisfies the first preset condition.

在本公开实施例中，第一预设条件可以包括以下a、b中的任一者：In an embodiment of the present disclosure, the first preset condition may include any of the following a and b:

a、调节阀处于关闭状态的持续时长达到第一预设时长。a. The duration of the regulating valve being in the closed state reaches a first preset duration.

其中，第一预设时长可以根据第一管路的布置情况和水泵的能力确定，使得调节阀处于关闭状态期间，管路排气系统中管路内的压力始终小于管路所能承受的最大压力值。Wherein, the first preset time length can be determined according to the layout of the first pipeline and the capacity of the water pump, so that when the regulating valve is in the closed state, the pressure in the pipeline in the pipeline exhaust system is always lower than the maximum pressure that the pipeline can bear.

Set the pressure (for example, 15MPa).

在调节阀32关闭后，控制模块1判断是否满足上述第一预设条件。若满足第一预设条件，则发送第二预设排气信号至调节阀32；若不满足第一预设条件，则继续监测是否满足第一预设条件。After the regulatingvalve 32 is closed, thecontrol module 1 judges whether the above-mentioned first preset condition is satisfied. If the first preset condition is met, then send a second preset exhaust signal to the regulatingvalve 32; if the first preset condition is not met, continue to monitor whether the first preset condition is met.

在本公开中，在调节阀32的开度调节为第一预设开度阈值前，调节阀32两端循环液的液压不一致，在开度调节调节为第一预设开度阈值时，第一管路的循环液快速涌进第二管路，循环液的流速快速增大，高流速的循环液将管路(尤其是管路拐角点和弯曲管道顶部位置处的气泡)中的气泡带走至排气装置2。另外，为了增加循环液的流速，以使得管路中的气泡尽快能排到排气装置2，上述第一预设开度阈值可以为100％。In the present disclosure, before the opening of the regulatingvalve 32 is adjusted to the first preset opening threshold, the hydraulic pressure of the circulating fluid at both ends of the regulatingvalve 32 is inconsistent. When the opening is adjusted to the first preset opening threshold, the second The circulating fluid in the first pipeline rushes into the second pipeline quickly, and the flow rate of the circulating fluid increases rapidly. The high-velocity circulating fluid will bring the air bubbles in the pipeline (especially the bubbles at the corners of the pipeline and the top of the curved pipeline) Go toExhaust 2. In addition, in order to increase the flow rate of the circulating fluid so that the air bubbles in the pipeline can be discharged to theexhaust device 2 as soon as possible, the above-mentioned first preset opening threshold can be 100%.

在本公开实施例中，第二预设条件可以包括以下c、d中的任一者：In an embodiment of the present disclosure, the second preset condition may include any of the following c and d:

c、调节阀的开度处于第一预设开度阈值状态的持续时长达到第二预设时长。c. The duration for which the opening of the regulating valve is in the first preset opening threshold state reaches a second preset duration.

其中，第二预设时长可以根据第一管路的布置情况和水泵的能力确定，使得第一管路内的压力降到管路排气系统处于正常循环状态时的管路压力范围内。Wherein, the second preset duration can be determined according to the layout of the first pipeline and the capacity of the water pump, so that the pressure in the first pipeline drops to within the pipeline pressure range when the pipeline exhaust system is in a normal circulation state.

d、第一管路内的压力降到第二预设压力。d. The pressure in the first pipeline drops to the second preset pressure.

在本公开中，调节阀32的开度从关闭调节为第一预设开度阈值，管路排气系统中管路内的压力降低，控制模块1还用于在调节阀32的开度调节为第一预设开度阈值后，实时判定第一管路内的压力是否降到第二预设压力，其中，第二预设压力位于管路排气系统处于正常循环状态时的管路压力范围内，并且，第二预设压力小于第一预设压力。In the present disclosure, the opening of the regulatingvalve 32 is adjusted from closed to the first preset opening threshold, and the pressure in the pipeline in the pipeline exhaust system is reduced. Thecontrol module 1 is also used to adjust the opening of the regulatingvalve 32 After reaching the first preset opening threshold, it is determined in real time whether the pressure in the first pipeline drops to the second preset pressure, wherein the second preset pressure is located at the pipeline pressure when the pipeline exhaust system is in a normal circulation state range, and the second preset pressure is lower than the first preset pressure.

在调节阀32的开度调节为第一预设开度阈值后，控制模块1判断是否满足上述第二预设条件。若满足第二预设条件，则发送第三排气信号至调节阀32；若不满足第二预设条件，则继续监测是否满足第二预设条件。After the opening of the regulatingvalve 32 is adjusted to the first preset opening threshold, thecontrol module 1 judges whether the above-mentioned second preset condition is satisfied.

At this time, since the second preset opening is smaller than the first preset opening, the first pipeline and the second The water resistance of the pipeline (that is, the pipeline of the pipeline exhaust system) increases, causing the flow rate of the circulating fluid to slow down. In this way, when the circulating fluid passes through theexhaust device 2, due to the slow flow rate, the air bubbles in the circulating fluid are likely to float out of the liquid surface, thereby being discharged from the exhaust device 2 (for example, discharged through the exhaust port on the exhaust device 2), realizing The pipeline exhaust system is automatically exhausted.

其中，第三预设时长可以根据第一管路的布置情况和水泵的能力确定，使得调节阀的开度处于第二预设开度阈值状态时，管路内的压力始终小于管路所能承受的最大压力值。Wherein, the third preset duration can be determined according to the layout of the first pipeline and the capacity of the water pump, so that when the opening of the regulating valve is in the second preset opening threshold state, the pressure in the pipeline is always lower than what the pipeline can handle. The maximum pressure value to withstand.

f、第二管路内的压力降到第三预设压力。f. The pressure in the second pipeline drops to a third preset pressure.

其中，如图3B和图3C所示，管路排气系统还包括设置在调节阀32与排气装置2之间的、用于检测第二管路内的压力的第二压力传感器5；控制模块1与第二压力传感器5连接，用于从第二压力传感器5获取第二管路内的压力，并在调节阀32的开度调节为第二预设开度阈值后，实时判定该第二管路内的压力是否降到第三预设压力，其中，第三预设压力小于第一预设压力，例如，第三预设压力略大于第一预设压力的一半。Wherein, as shown in FIG. 3B and FIG. 3C , the pipeline exhaust system also includes a second pressure sensor 5 arranged between the regulatingvalve 32 and theexhaust device 2 for detecting the pressure in the second pipeline; Themodule 1 is connected with the second pressure sensor 5, and is used to obtain the pressure in the second pipeline from the second pressure sensor 5, and after the opening degree of the regulatingvalve 32 is adjusted to the second preset opening degree threshold, determine the first pressure in real time. Whether the pressure in the second pipeline drops to a third preset pressure, wherein the third preset pressure is lower than the first preset pressure, for example, the third preset pressure is slightly greater than half of the first preset pressure.

在调节阀32的开度调节为第二预设开度阈值后，控制模块1判断是否满足上述第三预设条件。若满足第三预设条件，则需要判定排气是否完成，即执行以下步骤(9)；若不满足第三预设条件，则继续监测是否满足第三预设条件。After the opening of the regulatingvalve 32 is adjusted to the second preset opening threshold, thecontrol module 1 judges whether the above-mentioned third preset condition is satisfied. If the third preset condition is met, it is necessary to determine whether the exhaust is completed, that is, perform the following step (9); if the third preset condition is not met, continue to monitor whether the third preset condition is met.

(9)控制模块1判断管路是否满足初始排气条件。(9) Thecontrol module 1 judges whether the pipeline meets the initial exhaust conditions.

在本公开中，若管路满足初始排气条件，则表明管路排气系统排气未完成，控制模块1发送第一预设排气信号至调节阀32，返回上述步骤(2)继续进行排气，直到管路不满足初始排气条件时为止。若管路不满足初始排气条件，则表明管路排气系统已完成排气，此时，可以结束排气，恢复到正常循环状态，即执行以下步骤(10)和步骤(11)。In the present disclosure, if the pipeline meets the initial exhaust conditions, it indicates that the pipeline exhaust system exhaust is not completed, thecontrol module 1 sends the first preset exhaust signal to the regulatingvalve 32, and returns to the above step (2) to continue Exhaust until the pipeline does not meet the initial exhaust conditions. If the pipeline does not meet the initial exhaust conditions, it indicates that the exhaust system of the pipeline has completed the exhaust.

在上述实施方式中，通过不断切换调节阀的开度即可实现自动排气，并且，调节阀成本低廉，降低了系统成本。另外，由于整个排气过程无需水泵提供过大压力，因此，可以降低对水泵的功率需求，这样，使用低功率水泵就可满足管路排气系统的需求，进一步降低了系统成本。In the above embodiments, the automatic exhaust can be realized by continuously switching the opening of the regulating valve, and the regulating valve has low cost, which reduces the system cost. In addition, since the entire exhaust process does not require the water pump to provide excessive pressure, the power demand for the water pump can be reduced. In this way, the use of a low-power water pump can meet the needs of the pipeline exhaust system, further reducing the system cost.

在上述实施方式中，通过不断调整压力可调节水泵的压力即可实现自动排气，而无需设置调节阀，从而避免了因布置空间有限等原因导致的无法设置调节阀的问题。另外，压力可调节水泵的成本相对于真空加注机、外接排气装置的成本低，可以在实现管路排气系统自动排气的同时，控制系统成本。In the above embodiments, the pressure of the adjustable water pump can be adjusted continuously to realize automatic exhaust without setting a regulating valve, thereby avoiding the problem that the regulating valve cannot be installed due to limited layout space and the like. In addition, the cost of the pressure-adjustable water pump is lower than that of the vacuum filling machine and the external exhaust device, which can control the system cost while realizing the automatic exhaust of the pipeline exhaust system.

下面针对上述控制模块1判断管路是否满足初始排气条件的具体实施方式进行详细说明。具体来说，如图6A、图6B所示，排气装置2为水箱，水箱包括进气口m和排气口n，进气口m与管路连通，排气口n连通外部环境，上述管路排气系统还包括液位传感器8，设置在水箱内，用于实时检测水箱的液位。The following describes in detail the specific implementation of thecontrol module 1 judging whether the pipeline satisfies the initial exhaust conditions. Specifically, as shown in Fig. 6A and Fig. 6B, theexhaust device 2 is a water tank, and the water tank includes an air inlet m and an exhaust port n, the air inlet m communicates with the pipeline, and the exhaust port n communicates with the external environment. The pipeline exhaust system also includes a liquid level sensor 8, which is arranged in the water tank for real-time detection of the liquid level of the water tank.

控制模块1，与液位传感器8连接，还用于通过液位传感器8实时获取水箱的液位；控制模块1用于在水箱的液位在第七预设时长内的变化量大于预设液位阈值时，确定管路满足初始排气条件。Thecontrol module 1 is connected with the liquid level sensor 8, and is also used to obtain the liquid level of the water tank in real time through the liquid level sensor 8; When the threshold value is reached, it is determined that the pipeline meets the initial exhaust conditions.

在本公开中，当管路中有大量气体时，水泵31处于工作状态会增大管路压力，导致管路中的气体压缩，造成水箱给管路补充循环液，从而出现水箱液位变化。因此，通过监测水箱液位变化情况，来确定管路是否存在大量气体，并在确定存在大量气体时，确定管路满足初始排气条件。具体来说，控制模块1可以通过判断水箱的液位在第七预设时长(例如，0.5s)内的变化量是否大于预设液位阈值的方式来确定管路是否满足初始排气条件。其中，若水箱的液位在第七预设时长内的变化量大于预设液位阈值，则确定管路满足初始排气条件；若水箱的液位在第七预设时长内的变化量小于或等于预设液位阈值，则确定管路排气系统不满足初始排气条件In the present disclosure, when there is a large amount of gas in the pipeline, thewater pump 31 will increase the pressure of the pipeline when thewater pump 31 is in operation, resulting in the compression of the gas in the pipeline, causing the water tank to replenish circulating fluid to the pipeline, thereby causing the liquid level of the water tank to change. Therefore, by monitoring the change of the liquid level of the water tank, it is determined whether there is a large amount of gas in the pipeline, and when it is determined that there is a large amount of gas, it is determined that the pipeline meets the initial exhaust conditions. Specifically, thecontrol module 1 can determine whether the pipeline meets the initial exhaust condition by judging whether the variation of the liquid level of the water tank within the seventh preset time period (for example, 0.5s) is greater than the preset liquid level threshold. Wherein, if the change amount of the liquid level of the water tank is greater than the preset liquid level threshold within the seventh preset time length, it is determined that the pipeline meets the initial exhaust condition; if the change amount of the liquid level of the water tank within the seventh preset time length is less than or equal to the preset liquid level threshold, it is determined that the pipeline exhaust system does not meet the initial exhaust conditions

此外，为了避免水泵31空转或者堵转(即水泵通电、但不运转)导致管路排气系统损坏，在管路处于正常循环状态和排气过程中时，实时监测水泵是否异常，并在水泵异常时，控制水泵停止工作和/或发出异常告警。In addition, in order to avoid damage to the pipeline exhaust system caused by thewater pump 31 idling or blocked (that is, the water pump is energized but not running), when the pipeline is in a normal circulation state and in the process of exhausting, monitor whether the water pump is abnormal in real time, and check whether the water pump is abnormal. In case of abnormality, the water pump is controlled to stop working and/or an abnormal alarm is issued.

具体来说，如图7A、7B中所示，上述管路排气系统还包括流量传感器9，用于实时检测管路的流量；控制模块1还用于通过流量传感器9获取管路的流量，并判断流量是否超出预设流量范围，并在流量超出预设流量范围时，发送异常信号至压力调节装置3；压力调节装置3还用于接收异常信号，并停止工作和/或发出异常告警。Specifically, as shown in Figures 7A and 7B, the pipeline exhaust system also includes aflow sensor 9 for real-time detection of pipeline flow; thecontrol module 1 is also used to obtain pipeline flow through theflow sensor 9, And judge whether the flow exceeds the preset flow range, and when the flow exceeds the preset flow range, send an abnormal signal to thepressure regulating device 3; thepressure regulating device 3 is also used to receive the abnormal signal, stop working and/or issue an abnormal alarm.

在本公开中，若管路的流量超出预设流量范围，则表明水泵出现空转、堵转等异常，此时，为了避免管路排气系统损坏，压力调节装置3停止工作和/或发出异常告警；若管路的流量位于预设流量范围内，则表明水泵无异常，此时，可以继续监测水泵是否异常。In the present disclosure, if the flow rate of the pipeline exceeds the preset flow range, it indicates that the water pump has abnormalities such as idling and stalling. Alarm; if the flow of the pipeline is within the preset flow range, it means that the water pump is normal. At this time, you can continue to monitor whether the water pump is abnormal.
