Embodiment 1

[0024] Water-cooled thermoelectric refrigeration automobile air conditioner, its composition includes: semiconductor refrigeration plate 10, a group of water-cooled plates 9, air duct 1, fan 5, water pump 7, said a group of water-cooled plates 9 are fixedly connected with each other to form a jacket, four pieces The water-cooled plate 9 is connected with the angle steel 8 to form an outer jacket by threading, etc., the inside of the water-cooled plate 9 is fixed to the hot end of the semiconductor refrigerating sheet 10, and the cold end of the semiconductor refrigerating sheet 10 is fixed to the side wall of the air duct 1. The water-cooled plate 9 is connected to the water source and the water pump 7 through a pipeline to form a loop, the air duct 1 has an air inlet 3 and an air outlet 4, and the air inlet 3 is connected to the fan 5 through a pipeline, so The air outlet 4 is connected to the air supply pipe of the water-cooled thermoelectric refrigeration automobile air co...

Embodiment 2

[0026] The above-mentioned water-cooled thermoelectric refrigeration vehicle air conditioner, the circuit system includes: the control module 11 is connected in series with the vehicle battery 2, the circuit of the water pump 7, the circuit of the fan 5 and the circuit of the semiconductor refrigeration chip 10 are connected in parallel and then connected with the control module 11 in series, and then form a loop with the on-board storage battery 2. The control module has a time-delay switch, which controls the fan water pump and the semiconductor refrigeration chip respectively. When the control module button is turned on, the semiconductor cooling chip is powered on, the fan is powered on after 1 minute, and the water pump is powered on after 4 minutes.

Embodiment 4

[0028] In the above-mentioned water-cooled thermoelectric refrigeration automobile air conditioner, the water source is the vehicle-mounted cooling water tank. There is a serpentine coil in the water-cooled plate, and cooling water flows through the serpentine coil, and the water inlet and outlet of the serpentine coil are connected with the vehicle-mounted cooling water tank through a water pump to form a circuit. After the water pump is powered on, the water in the water-cooled plate starts to circulate with the water in the water tank, taking away the heat generated by the hot end of the semiconductor refrigeration chip, and ensuring that the temperature of the cold end reaches the standard.

Abstract

The invention discloses a water-cooling thermoelectricity refrigeration automotive air conditioning. The traditional water-cooling thermoelectricity refrigeration automotive air conditioning needs to consume 10-15% of power of a vehicle main engine to operate, the refrigeration capability is affected by the vehicle driving speed, therefore the comfort requirement can not be satisfied. The water-cooling thermoelectricity refrigeration automotive air conditioning comprises a semiconductor refrigeration sheet (10), an air flue (1) and a fan (5), wherein one group of water-cooling plates (9) are mutually fixedly connected to form an outer sheath; the hot end of the semiconductor refrigeration sheet is fixed on the inner side of the water-cooling plate; the cold end of the semiconductor refrigeration sheet (10) is fixed on the side wall of the air flue; the water-cooling plates are connected with a water source by virtue of pipelines and form a loop together with a water pump; the air inlet (3) of the air flue is connected with the fan (5) by virtue of a pipeline; the air outlet (4) of the air flue is connected with the air supply pipe of the water-cooling thermoelectricity refrigeration automotive air conditioning by virtue of a pipeline; and the semiconductor refrigeration sheet is connected with a circuit system. The product is used for an air conditioning system.

Description

technical field [0001] The invention relates to a water-cooled thermoelectric refrigeration system for automobile air conditioners. Background technique [0002] With the popularization of the application of automotive air conditioners, people are paying more and more attention to the impact of automotive air conditioners on the car itself and the environment. Traditional compression refrigeration air conditioners need to consume 10%-15% of the power of the main engine of the car during operation, resulting in a direct impact on The acceleration performance and climbing ability of the car; and its cooling capacity is also affected by the speed of the car. If the car engine stops working, the air-conditioning system in the car also stops running at the same time, resulting in the car air-conditioning cannot meet the comfort requirements of passengers. For this purpose, a car air conditioner with no refrigerant, no noise, no leakage, no pollution, safety and environmental prot...
