[0002] The semiconductor cooling chip is also called a thermoelectric cooling chip. It is a heat pump. Its advantage is that it does not require any refrigerant and can work continuously. There is no pollution source, no rotating parts, no gyration effect, and no sliding parts. There is no vibration, noise, and long life during operation. It uses the Peltier effect of semiconductor materials. When direct current passes through a galvanic couple made of two different semiconductor materials in series, heat can be absorbed and released at both ends of the galvanic couple. Realize the purpose of cooling and heating; however, most of the previous semiconductor incubators were only used for a single function at the same time. When used as a cold preservation function, the heat energy was indirectly discharged out of the box through cooling fins and fans; as a heat preservation function In this case, the heat energy is indirectly absorbed from the outside of the box through the heat dissipation fins and the fan, and then the heat energy is conducted into the box through the semiconductor chip for heat preservation; that is to say, the existing technology only considers the heat release or heat absorption part, so at least Half of the energy is wasted and it will increase the power consumption of the fan

[0003] A small number of dual-temperature semiconductor incubators that emphasize energy saving consider both heat absorption and heat release, but they are all equipped with heat dissipation fins, fans or condensate pipes to achieve the purpose of local control of heat absorption or heat release, so that the semiconductor The refrigerating sheet can convert the absorbed heat energy into heating or hot water while keeping the cold; The cooling chip is a low-power cooling and heating component. It is used in an air conditioner that needs instant heating and cooling, and the effect is very limited. It is also used in the supply of hot water and ice water, and it cannot be used due to the space limitation in the incubator. Sufficient warm water is supplied, so that the market acceptance of existing dual-temperature semiconductor incubators cannot be improved.
