A semiconductor interior cooling system based on solar energy

Abstract

The invention relates to a semiconductor car interior cooling system based on solar energy. The semiconductor car interior cooling system based on the solar energy comprises a power module, a voltage stabilizing circuit and a single chip microcomputer control module and further comprises a refrigeration device. The power module produces a direct current under irradiation of sunlight. The voltage stabilizing circuit stabilizes output voltage and supplies electric energy to the single chip microcomputer control module and the refrigeration device at the same time. The refrigeration device is used for cooling the interior of a car by providing cool air. The single chip microcomputer control module is used for controlling the whole system. According to the semiconductor car interior cooling system based on the solar energy, power can be generated through a solar cell panel placed at the top of the car under the condition that the car is exposed in the sun, meanwhile, the interior of a carriage is refrigerated through the Peltier effect of a semiconductor refrigeration piece, and thus the relatively suitable temperature can be kept in the car.

Description

technical field [0001] The invention relates to a semiconductor interior cooling system based on solar energy, which belongs to the technical field of semiconductor refrigeration. Background technique [0002] In summer, when the car is parked in a sunny place for a long time, because the car will absorb the sun's radiant heat through the outer shell in the sun, the infrared rays in the sun will also pass through the glass window to bring heat to the items and seats in the car. The temperature in the chair, the outside ground and the air is also very high, which will radiate and conduct heat to the car. The interior of the car is relatively closed, and the heat is not easy to dissipate, resulting in a high temperature inside the car. At present, the common solution is to open the door to dissipate heat for a period of time before using the car. If you are in a hurry, you will directly turn on the air conditioner to dissipate heat. The car air conditioner is generally drive...

AI Technical Summary

Problems solved by technology

The design of the device is reasonable, using solar photovoltaic power generation technology and semiconductor refrigeration technology, which saves energy, is safe and environmentally friendly, but because the device puts the semiconductor cooling chip in the trunk of the car, a large amount of heat generated by the semiconductor hot end will be transferred to the car. The cooling effect is greatly reduced; and in the airtight trunk, the heat generated by the hot end of the semiconductor cooling chip cannot be dissipated in time only through air cooling, which will cause the temperature of the hot end to rise sharply, and even cause damage to the semiconductor chip

[0006] To sum up, the existing solar semiconductor interior cooling technology generally has shortcomings such as poor cooling effect, insufficient heat dissipation at the hot end of the semiconductor, more structural modifications to the car itself, and poor security of the entire system. How to overcome the existing technology The deficiency has become one of the key problems to be solved urgently in the field of current flow solar semiconductor refrigeration technology
