.Not available in practical applications. Experiments have proven that introducing a third material into the cabinet air conditioner temperature difference circuit will not change the characteristics of the circuit. In this way, the cabinet air conditioner semiconductor components can use various connection methods to meet the user's requirements. The cabinet air conditioner connects a single-type semiconductor element and a single-type semiconductor element to form a pair of thermocouples.
After the cabinet air conditioner is connected to the DC power supply, a temperature difference and heat transfer will occur at the joint. , the temperature drops and absorbs heat, this is the cold end, and at a joint below, the direction of the current is from to, the temperature rises and releases heat, so it is the hot end. Type materials have extra electrons and have negative thermoelectric potential.
. The mold material used in the cabinet air conditioner has insufficient electrons and has a positive temperature difference potential. When the electrons pass through the node from the mold to the mold, the temperature of the node decreases, and its energy will inevitably increase, and the increased energy is equivalent to the energy of the node. energy consumed. Conversely, as electrons flow from the mold to the mold material, the temperature of the junction increases.
