Automatic rapid cooling system for vehicle-mounted seat and cooling method thereof

Abstract

The invention relates to a cooling system for a vehicle-mounted seat, in particular to an automatic rapid cooling system for the vehicle-mounted seat and a cooling method thereof. The automatic rapidcooling system mainly comprises a heat dissipation system, a refrigeration system and a vehicle-mounted seat system, wherein the heat dissipation system and the refrigeration system are associated andmounted through a tank body of the same water tank and are in temperature conductive connection with the vehicle-mounted seat system; the vehicle-mounted seat system mainly involves a vehicle-mountedseat, a heat dissipation conduction device, an intelligent control device and a power supply; the refrigeration system mainly involves the refrigeration water tank, a secondary refrigerant, a heat pipe radiator, a heat conduction silicone grease layer, a semiconductor chilling plate, an input port and an output port; and the heat dissipation system is arranged above the refrigeration water tank,and mainly comprises a heat dissipation assembly, a U-shaped heat pipe and an aluminum plate. According to the cooling system, the heat dissipation system is combined with the refrigeration system toact on the vehicle-mounted seat system, the secondary refrigerant is adopted during working operation, the heat transfer coefficient can be remarkably improved, the efficiency and the lifetime of thesemiconductor chilling plate are effectively improved, and defects existing in a traditional used cooling mode are completely overcome.

Description

technical field [0001] The invention relates to a cooling system for a vehicle seat, in particular to an automatic rapid cooling system for a vehicle seat and a cooling method thereof. Background technique [0002] The temperature inside the car after exposure to the sun is extremely high, and the surface temperature of the seat is even higher. Although the current car is equipped with an air-conditioning system, the system can only be operated when the car is started to achieve cooling effect, and the temperature of the seat is difficult to drop in a short time. At present, there is a precedent in the market for applying semiconductor refrigeration technology to the temperature adjustment of the front seats. This technology adjusts the temperature of the front seats by controlling the temperature controllable seat button switches of the driver and passengers. The system operation of the temperature-controlled seat is independent of the cooling system and control system of ...

AI Technical Summary

Problems solved by technology

[0003] This application technology can achieve a certain degree of cooling effect, but the application range is small. In this application technology, due to the low air convection heat transfer coefficient used, the cooling capacity of the semiconductor cannot be transferred to the seat cushion and seat back in time. As a result, semiconductor refrigeration has low efficiency, short life, and bulky volume, which seriously affects the effect of semiconductor refrigeration; and there is a defect that people sitting on it will inevitably block the air inlet of the seat, reducing the air volume passing through the seat and reducing the cooling effect

The scope of application cannot be expanded, so the current method of seat cooling is still a difficult problem to solve
