Solar cooling is the use of semiconductor solar cells produce electricity to drive the thermoelectric cooling devices, heat transfer to achieve a special cooling means. Semiconductor solar-driven refrigeration system, compact, easy to carry, it has to use and easy maintenance, security, performance, storage more convenient, no pollution and so on. Through the principles of semiconductor refrigeration technology analysis and research, while the car refrigerator on the market research on the design of a solar semiconductor refrigerator car. Solar array to accept the sun during the day, through the photoelectric conversion effect of sunlight into electrical energy. DC output, can supply a part of the semiconductor refrigerator, the other part into the battery storage, can provide lasting power in the night. Film cooling surface and the cooling surface heating and cooling bodies and were pressed in contact with the aluminum block. Polyurethane foam insulation is effective insulation, refrigeration cooling the cold end piece, hot-side heat dissipation through the fan will go out. The refrigeration equipment refrigerator temperature can be reduced to below 15 ℃, can be used for field construction, exploration, hiking and other outdoor activities, archaeological and preservation of food and beverages can also be used for food, beverage and medical vaccine refrigeration and so on.

Solar of semiconductor refrigeration's energy battery produces electricity to drive the semiconductor refrigeration equipment, realize heat transfer of special refrigeration way. Solar drive of semiconductor refrigeration system, the structure is compact, easy to carry, it has to use simple maintenance, safety performance is good, energy storage is more convenient, no environmental pollution etc. Characteristics. Based on the principle of semiconductor refrigeration technology analysis and research on the market, and in the research on the car refrigerator design a car solar semiconductor refrigerators. During the day the sun battery array accept the sun, through the photoelectric effect will sunlight into electricity. The output of dc, part can directly supply semiconductor refrigerator, another part into the battery storage, can provide enduring power in the evening. Refrigeration ?
