一种便携式太阳能冰箱A portable solar refrigerator

技术领域technical field

本发明涉及到光电制冷领域，特别是涉及到一种可在家用、车载、户外(太阳能)条件下使用的便携式太阳能冰箱。 The invention relates to the field of photoelectric refrigeration, in particular to a portable solar refrigerator that can be used at home, on a vehicle, or outdoors (solar energy). the

背景技术Background technique

近年来，环境污染越来越严重，能源短缺问题甚为突出。随着经济的发展和生活水平的不断提高，人们对节能环保的关注日益密切、要求日益升高。太阳能作为一种清洁的可再生能源越来越受到人们的重视，太阳能光伏电池具有许多其它发电方式无法比拟的优点，包括不消耗燃料、不受地域限制、规模灵活、无污染、安全可靠、维护简单且寿命较长等。太阳能制冷的应用与太阳能的供给具有较好的一致性：夏季天气越热、太阳辐射越强的时候，需要的冷量负荷也越大。 In recent years, environmental pollution has become more and more serious, and the problem of energy shortage is very prominent. With the development of the economy and the continuous improvement of living standards, people pay more and more attention to energy conservation and environmental protection, and their requirements are increasing. As a clean and renewable energy source, solar energy has attracted more and more attention. Solar photovoltaic cells have many advantages that other power generation methods cannot match, including no fuel consumption, no geographical restrictions, flexible scale, no pollution, safety and reliability, maintenance Simple and long life etc. The application of solar cooling is consistent with the supply of solar energy: the hotter the weather in summer and the stronger the solar radiation, the greater the cooling load required. the

现用冰箱的使用需要消耗大量常规能源，间接对环境造成严重污染。现用冰箱体积大，能源单一，局限性严重，不便携。对长时间、户外跨地域(户外医疗冷冻保藏、户外冷冻需要等)等情况应用有很大的局限性。现用冰箱虽然具有多个冷藏冷冻室，但是各个藏室目标温度并不能随用户要求更改，无法满足人们对不同温度制冷的灵活需求。 The use of existing refrigerators consumes a large amount of conventional energy, which indirectly causes serious pollution to the environment. Existing refrigerators are bulky, have a single energy source, have severe limitations, and are not portable. There are great limitations for long-term, outdoor cross-regional applications (outdoor medical cryopreservation, outdoor freezing needs, etc.). Although existing refrigerators have multiple refrigerating and freezing compartments, the target temperature of each storage compartment cannot be changed according to user requirements, which cannot meet people's flexible needs for refrigeration at different temperatures. the

现有的太阳能光电冰箱：如专利“一种太阳能冰箱”(公开号：CN201611197U)、专利“便携式太阳能冰箱”(公开号：CN201885503U)，两者将太阳能电池板安装在冰箱顶端，虽然可以折叠、滑移或者拆卸，但由于多块太阳能电池板的存在，大大增加了太阳能冰箱的体积与质量，不便携带。而且上述专利虽然提到蓄电池的应用，但是在室内、车载运输途中应用并未提及，只靠蓄电池难以维持长时间连续制冷。专利“便携式太阳能冰箱”(公开号：CN201926229U)，虽将电池板设置在盖体并考虑安装把手便于携带，但并未考虑箱体的综合运用以及制冷方式的选取。 Existing solar photoelectric refrigerators: such as the patent "a solar refrigerator" (public number: CN201611197U) and the patent "portable solar refrigerator" (public number: CN201885503U), both of which install solar panels on the top of the refrigerator, although they can be folded, Slip or disassemble, but due to the existence of multiple solar panels, the volume and quality of the solar refrigerator are greatly increased, making it inconvenient to carry. And although the above-mentioned patent mentions the application of the storage battery, it is not mentioned in the indoor and vehicle transportation, and it is difficult to maintain continuous refrigeration for a long time only by the storage battery. The patent "Portable Solar Refrigerator" (publication number: CN201926229U), although the battery board is arranged on the cover and the handle is considered to be easy to carry, does not consider the comprehensive use of the box and the selection of cooling methods. the

发明内容Contents of the invention

本发明的目的在于克服传统冰箱的不便携、用电来源单一的局限性，提供一种便携式太阳能冰箱，不仅满足人们在家用中冷冻需求，而且能方便的在车载、户外等特殊场合提供连续性冷冻，温度可操控性强、节能环保、智能便携，可更好地方便和满足人们的生活和使用要求。 The purpose of the present invention is to overcome the limitations of traditional refrigerators that are not portable and have a single power source, and provide a portable solar refrigerator, which not only meets people’s needs for freezing at home, but also can conveniently provide continuity in special occasions such as vehicles and outdoors. Freezing, strong temperature controllability, energy saving and environmental protection, smart and portable, can better facilitate and meet people's life and use requirements. the

为实现上述目的，本发明便携式太阳能冰箱由制冷系统、温控系统、电源转化系统、附属件组成。制冷系统包括冷凝器、储液器、过滤器、膨胀阀、蒸发器、直流压缩机、风扇。用管道连接成一个密封的系统。从箱体内蒸发器完成热交换汽化产生的低压蒸汽被压缩机吸入压缩成高温高压气体，进入冷凝器被空冷成高压液体，经过滤器膨胀阀最后进入蒸发器，蒸发吸热完成制冷循环。温控系统包括热电偶、温度控制器及连接导线。安装在箱体上的热电偶测量其冰箱内部温度，传给温控器，温控器根据设定的温度T及温差Δt，合理控制压缩机的运行。电源转化系统包括蓄电池、220V电源插头、车载电源插头、太阳能电池板片、连接导线。在不同环境中，用户可根据需要使用不同的电源，更加方便合理使用。电源转化器将不同来源电能，转化成压缩机特定电流电压，保证其稳定运行。附属件包括滑轮底板、嵌入太阳能电池板片的冰箱壳体。蓄电池、控制系统和温控器放置在冰箱一侧，与冰箱合为一体，其中蓄电池、滑轮底座可拆卸，方便携带。 In order to achieve the above object, the portable solar refrigerator of the present invention is composed of a refrigeration system, a temperature control system, a power conversion system and accessories. Refrigeration system includes condenser, liquid receiver, filter, expansion valve, evaporator, DC compressor, fan. Connect with pipes to form a sealed system. The low-pressure steam produced by heat exchange and vaporization from the evaporator in the box is inhaled by the compressor and compressed into a high-temperature and high-pressure gas, enters the condenser, is air-cooled into a high-pressure liquid, passes through the filter expansion valve, and finally enters the evaporator, where it evaporates and absorbs heat to complete the refrigeration cycle. The temperature control system includes thermocouples, temperature controllers and connecting wires. The thermocouple installed on the box measures the internal temperature of the refrigerator and transmits it to the thermostat. The thermostat reasonably controls the operation of the compressor according to the set temperature T and the temperature difference Δt. The power conversion system includes batteries, 220V power plugs, vehicle power plugs, solar panels, and connecting wires. In different environments, users can use different power supplies according to their needs, which is more convenient and reasonable to use. The power converter converts electric energy from different sources into a specific current and voltage of the compressor to ensure its stable operation. Accessories include a pulley base plate and a refrigerator housing with embedded solar panels. The accumulator, control system and temperature controller are placed on one side of the refrigerator and are integrated with the refrigerator. The accumulator and the pulley base are detachable for easy portability. the

在室内，将电源插头插入220V电源插座，便携式太阳能冰箱利用照明电运行；在室外，太阳能电池板将太阳能转化成12V电压，通过电源转变系统稳压稳流，推动无刷直流电动压缩机运转；也可以将车载线插入汽车电源插口，利用车载电池电源直接驱动。蓄电池可弥补在户外因太阳能具有时间性而导致冰箱只能白天工作的缺点，把白天产生的一部分富余电能蓄存起来；也可以采用家用220V电源给蓄电池充电，克服由于天气、昼夜带来的间隙性，实现无间断全天候制冷。通过温度控制器对压缩机进行变频控制：温控器可设定冰箱壳内温 度T、温度差Δt，在箱内温度达到T+Δt后，压缩机变频，转速降低，低于T-Δt后，压缩机断电停止工作。太阳能电池板片直接嵌入冰箱外壳(与外壳融为一体)。 Indoors, plug the power plug into a 220V power outlet, and the portable solar refrigerator operates with lighting electricity; outdoors, the solar panel converts solar energy into 12V voltage, and the power conversion system stabilizes the voltage and current to drive the brushless DC electric compressor to run; You can also plug the car cable into the car power socket and use the car battery power to drive directly. The battery can make up for the shortcoming that the refrigerator can only work during the day due to the time nature of solar energy, and store a part of the surplus electric energy generated during the day; it can also use a household 220V power supply to charge the battery to overcome the gap caused by weather and day and night performance, to achieve uninterrupted all-weather cooling. The frequency conversion control of the compressor is carried out through the temperature controller: the temperature controller can set the temperature T in the refrigerator shell and the temperature difference Δt. After the temperature in the box reaches T+Δt, the frequency of the compressor will be converted, and the speed will decrease, which is lower than T-Δt. After that, the compressor will stop working. The solar panels are embedded directly into the refrigerator shell (integrated with the shell). the

本发明的有益效果是，可以在不同场合(家用、车载、户外)，不同区域为人们提供连续性制冷，结构简单、节能环保、智能便携，满足人们不同需求，更好的为生活提供了便利。 The beneficial effect of the present invention is that it can provide people with continuous refrigeration in different occasions (household, vehicle, outdoor) and different areas, with simple structure, energy saving, environmental protection, intelligent and portable, meeting different needs of people, and better providing convenience for life . the
