Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
In the vehicle-mounted air conditioning system based on the thermoelectric effect in the embodiment, a plurality of the refrigerating (heating) devices 1 are arranged in the cab, the air outlet of each refrigerating (heating) device 1 faces to different parts of the body of a driver, and the number of the refrigerating (heating) devices 1 is determined according to the number of temperature sensing parts required by the driver. This example will be described with reference to the face, chest, and back of the driver. Namely, the present embodiment is provided with three cooling (heating) devices 1 in the automobile cab, and the three cooling (heating) device air outlets blow to the face, chest and back of the driver, and the specific positions are shown in fig. 1 and 8.
Three refrigeration (heat) device 1 share a set of cooling system, radiator 13 is arranged at the air intake of car, and water pipe 11 is arranged in the pipeline of automobile body inside, and water flows out from radiator 13 delivery port and water pump 12, adopts a one-to-three switching port to divide the water route into three parallelly connected, flows in the hot junction cooling water tank 10 of three refrigeration (heat) device respectively, and the water that flows out from three hot junction cooling water tank 10 passes through trinity adapter, converges water pipe 11 and communicates to the radiator water inlet. The two semiconductor refrigerating sheets 4 in each refrigerating (heating) device adopt a parallel circuit, the centrifugal fan 5 and the semiconductor refrigerating sheets 4 are respectively provided with a power regulator, the voltage of the electric device of the air conditioning device is 12V, and the electricity is supplied from the storage battery of the vehicle.
When the refrigeration working condition is met, the water pump 12 works, the water-cooling radiator 13 starts to function, and the power regulator connected with the semiconductor refrigeration sheet 4 is adjusted to a certain working condition. At the moment, because the Peltier effect in the thermoelectric effect of the semiconductor material plays a main role, the semiconductor refrigeration sheet 4 forms a temperature difference, wherein the high temperature of the hot end is transferred to the hot end cooling water tank 10 through heat conduction, the cooling water in the hot end cooling water tank 10 is driven by the water pump 12 to reach the water-cooling radiator 13 through the water pipe 11 to dissipate heat, the cold end of the semiconductor refrigeration sheet 4 transfers the heat to the cold end heat exchange fins 6 through heat conduction, in order to avoid the heat loss of the cold end heat exchange fins 6, the heat is concentrated by the acrylic heat insulation plate 7, the centrifugal fan 5 gives a wind speed through the power regulator, and finally the centrifugal fan 4 sends the heat on the cold end heat exchange fins 6 into the cab.

The water pump 12 is stopped and the water-cooled radiator 13 is turned off. The semiconductor refrigerating piece 4 still can produce the difference in temperature this moment, but owing to do not have the heat dissipation, this end temperature can continuously climb, and the generating temperature difference ability of refrigerating piece is certain, and both ends temperature rise simultaneously. The semiconductor refrigerating sheet 4 plays a role similar to an electric heating wire and becomes a heating source of the heating working condition, the generated heat is transferred to the cold-end heat exchange fins 6 through heat conduction, and the heat insulation plate 7 enables the heat to be gathered and finally blown out from the air outlet through the centrifugal fan 5.
