一种双向抽气式电缆冷却器A two-way suction type cable cooler

技术领域technical field

本申请涉及一种冷却设备，具体为一种双向抽气式电缆冷却器。The present application relates to a cooling device, in particular to a two-way suction type cable cooler.

背景技术Background technique

在工厂中的大型用电设备通常需要配备大型配电箱；由于大规模的工业生产需要大量的这种配电箱，因此，在工厂的配电车间中通常设置有对应的大量配电箱。由于工业设备的用电量和功率较大，因此，向配电箱供电的电缆在长时间大电流作用的情况下容易发生热量积聚。尤其是在配电箱内部走线的电缆，由于配电箱内部的散热情况不佳，而且配电箱内部的电气元件本身也在散发热量，因此，这些情况的叠加就更加加剧了热量的累积。累积的热量对于工厂的配电车间造成巨大的安全隐患。由于配电车间人员较少，设备较多，长时间的热量累积容易造成电缆外皮软化，加重老化程度，而且在接触其他物体的情形下容易逐渐引燃接触物体，造成火灾。现有的一些冷却装置，通常是在配电箱上加装排风扇，以便将热量散开。但是，这种装置只是将热量排放到车间环境中，不能实现车间整体的降温降险；而且，配电箱中通常电气元件密集，在某些热量积聚的区域中，排风效果往往不好，因此这种装置也难以对具体的部件进行针对性降温。而现有技术中也有对于特定的具体部件加装风扇的设备。但是，这样仅仅是将该具体部件的热量排放到其他部件周围，并不利于整体的降温。而且现有技术中的电缆冷却器结构比较复杂，操作可靠性不高，需要耗费额外的电力。Large-scale electrical equipment in a factory usually needs to be equipped with a large distribution box; since large-scale industrial production requires a large number of such distribution boxes, a large number of corresponding distribution boxes are usually provided in the power distribution workshop of the factory. Due to the high power consumption and power of industrial equipment, the cables supplying power to the distribution box are prone to heat accumulation under the condition of long-term high current. Especially for the cables routed inside the distribution box, due to the poor heat dissipation inside the distribution box, and the electrical components inside the distribution box are also dissipating heat, the superposition of these conditions will further aggravate the accumulation of heat . The accumulated heat poses a huge safety hazard to the factory's power distribution workshop. Since there are fewer personnel and more equipment in the power distribution workshop, long-term heat accumulation is likely to cause softening of the cable sheath and aggravate the aging degree, and it is easy to gradually ignite the contact object in the case of contact with other objects, causing a fire. In some existing cooling devices, an exhaust fan is usually added to the distribution box to dissipate the heat. However, this device only discharges heat into the workshop environment, and cannot reduce the overall temperature and risk of the workshop; moreover, the electrical components are usually dense in the distribution box, and the exhaust effect is often not good in some areas where heat accumulates. Therefore, this device is also difficult to carry out targeted cooling of specific parts. And the prior art also has the equipment that fan is installed additionally for specific concrete parts. However, this only discharges the heat of the specific component to other components, which is not conducive to overall cooling. Moreover, the structure of the cable cooler in the prior art is relatively complicated, the operation reliability is not high, and extra power consumption is required.
