Cushion with heating and refrigerating functions for car seat and heating and refrigerating method of cushion

Abstract

The invention relates to a cushion with heating and refrigerating functions for a car seat. The cushion comprises a heating and refrigerating device, a heat absorbing and dissipating box and a cushionbody. The heating and refrigerating device comprises a bottom plate, a small-power air conditioner compressor, a water pump and a first copper pipe, and the cushion body comprises a high molecule thin film on the upper layer and a high molecule thin film on the lower layer. A conducting liquid pipe at one end of a high molecule pipe communicates with a hollow conducting liquid channel at one edgeof the cushion body, and the other end of the high molecule pipe communicates with a hollow conducting liquid channel at the other edge of the cushion body. The heat absorbing and dissipating box comprises a metal shell and a second copper pipe, the metal shell is a sealed metal shell, and the hollow conducting liquid channels, a conducting liquid flowing cavity channel and the conducting liquidpipe are filled with conducting liquid. The cold and hot conducting liquid is generated through refrigerating and heating of the heating and refrigerating device, then the heated or refrigerated conducting liquid circulates in a reciprocating mode in the cushion with the heating and refrigerating functions for the car seat, and thus the cooling and heating effects are achieved; and according to the cushion, the refrigerating and heating speeds are high, energy consumption is little, the structure is simple, the comfort is high, and the safety and reliability are high.

Description

technical field [0001] The invention relates to a heating and cooling pad for an automobile seat and a heating and cooling method thereof, belonging to the technical field of heating and cooling pad device design. Background technique [0002] With the development of society, cars have become an indispensable means of transportation, and people's requirements for car seats are getting higher and higher. In the hot summer, when the door of a car parked outside is opened, the temperature inside the car is extremely high, like a steam room, and the seats are unbearably hot. Even if the car has not been exposed to the sun, if the owner drives or sits in the car for a long time, even if the air conditioner is turned on, the bottom of the buttocks and the backrest are still wet and hot, which may not only cause eczema, acne and other diseases, but also make the driver unable to concentrate on driving the car , thereby increasing the risk factor of driving. In the cold winter, wh...

AI Technical Summary

Problems solved by technology

[0003] There are also several seat products on the market that can cool down and heat up. As far as cooling is concerned, none of them actively cool down, but are achieved by blowing air from a fan placed under the seat. The effect is not obvious, the cooling speed is slow, and the car No effect at higher internal temperatures

There are also some products that use silicon wafer cooling, but it is slow and consumes a lot of energy

As far as heating is concerned, the existing seat is heated by electric heating wire, which is easy to catch fire due to electric leakage, which is very unsafe
