Water-cooling thermoelectricity refrigeration automotive air conditioning

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...

AI Technical Summary

Problems solved by technology

Although the air cooling method is simple and convenient, its efficiency is very low; heat pipe cooling does not require additional energy sources, but its efficiency is still low

The cooling capacity of the semiconductor cooling plate is directly transferred to the air through the wall of the air duct, the heat transfer efficiency is low, and it cannot really meet the heat dissipation requirements of the hot end, so that it affects the cooling capacity of the cold end

Moreover, the existing semiconductor refrigerating sheets are generally only arranged on the upper and lower sides of the air duct, so that when exchanging heat with the internal cold air duct, the heat transfer will not be uniform enough, and the temperature of the air outlet cannot be guaranteed.

This leads to uneven temperature of the air outlet, which reduces the comfort of the air conditioner.
