Description
(1) technical field
The utility model relates to a kind of additional device of automobile, is specially a kind of automotive seat refrigeration system.
(2) technical background
It is Facing material that automotive seat now all adopt leather, textiles, fills a large amount of whippy materials in it, and it is soft comfortable that seat is sat up.But when scorching temperature weather, even the cold air in the automobile is open, such seat is sat and also can be made the people feel scorching discomfort long afterwards.Particularly in summer time, when entering in the long-time parked automobile, seat is burning hot, is difficult to take a seat.Even after opening the interior air-conditioning of car, the cold air of vehicle interior space also is difficult to make the very fast cooling of thick and heavy cushion, make the person of taking advantage of as being seated on the heat pot, can only stand.In order to solve the problem that automotive seat cool, existing multiple patent application, as Chinese patent " seat cooling mechanism ", the vessel vehicle internal cooling system that the cold liquid of splendid attire is set in car is communicated with, make cold liquid in container and cushion water channel intercropping circulation with water pump, to seat refrigeration, this design need add a cover self contained system in addition, and complex structure, cost height, the space that occupies are big.Chinese patent " automotive seat cooling mechanism ", " cold, the warm seat of air conditioning automobile ", " air conditioner for automobile air cushion ", " method and apparatus of automotive seat down quench " etc., main design plan all is that the cold wind outlet at air conditioning for automobiles picks out pipeline and inserts in the air channel or air bag of seat, the direct irrigation and drainage of cold air are lowered the temperature in seat, the method has influenced the refrigeration and the normal wind circulation of air conditioning for automobiles of automobile bodies air, makes air-conditioner efficiency reduction in the car, increases engine load.
My last patent application " fridge equipments of automotive seat " with introducing in the seat cooling assembly through the dichlorodifluromethane after once circulating in the a/c system, is played the effect that reduces seat temperature; Therefore this design does not increase the excess power of refrigeration system and the additional device of automobile because what utilize is that remaining cold in a/c system freezes to automotive seat, and simple in structure, expense is cheap, and is easy to operate.But only depend in the car remaining cold behind the air-conditioning refrigerant and air in a car compartment interchange of heat, too low to the rate of cooling of seat.
Existing scheme all has deficiency, still needs and wants further perfect automotive seat refrigeration system.
(3) utility model content
The purpose of this utility model is a kind of automotive seat refrigeration system of design, can reduce the temperature of each seat in the automobile quickly and effectively simultaneously, and can change automatically regulating according to seat temperature.
The utility model design-calculated automotive seat refrigeration system comprises air-conditioning refrigeration system and the one or more seat heat exchanger assembly in the car.Automobile air conditioning refrigerating system comprises by compressor, condenser, expansion valve, evaporator, height pressure pipe, each unit Series.Each seat heat exchanger assembly has ingress pipe and delivery line.There is the seat branch road of one or more seat heat exchanger assemblies to be parallel between the high-low pressure pipeline of evaporator.
High-pressure pipe at the condenser mouth connects Highpressure Tee, and an arm of Highpressure Tee is connected with expansion valve, evaporator, and another arm is connected with the seat branch road.Promptly, be connected with the ingress pipe of each seat heat exchanger assembly through seat branch road expansion valve, flow divider valve.The mouth of evaporator is connected with an arm that reclaims threeway, and the delivery line of each seat heat exchanger assembly inserts combiner valve, and the combiner valve mouth is connected with another arm that reclaims threeway.The 3rd arm that reclaims threeway inserts compressor through the low pressure Through Flow Line (TFL).
The native system service condition is: the compressed machine compression of refrigerant back enters into condenser by high-pressure pipe, with under the high pressure during gas-liquid phase transition liberated heat be discharged to outside the automobile, refrigerant is divided into two-way through Highpressure Tee then, one the tunnel directly enters evaporator through expansion valve, absorbs the heat of air in the automobile bodies when refrigerant sharply expands liquid-gas phase transition; Another road refrigerant then through seat branch road expansion valve, enter flow divider valve and be further divided into a plurality of branch roads, enter each seat heat exchanger assembly through ingress pipe, absorb the heat of each seat.Finish refrigerant behind the interchange of heat through the delivery line of each seat heat exchanger assembly after combiner valve is converged, enter the recovery threeway with the refrigerant of evaporator output, return compressor through the low pressure Through Flow Line (TFL).
For the temperature of regulating control seat, shut off valve also is housed on the high-pressure pipe that enters the seat branch road, control enters the refrigerant flow of seat branch road.Be the temperature of automatic guidance seat, thermal detector is installed on the seat, its signal is sent into automatic control circuit board, this circuit card is connected with the shut off valve of electromagnetic signal control, according to the temperature signal of seat, the size that the control shut off valve is opened, i.e. control enters the amount of the refrigerant of seat branch road.
For making the cooling rate of each different seat of distance distance, each branch road output bore scalable of flow divider valve makes the refrigerant flow difference that enters each seat, and makes far and near seat cooling rate unanimity.
The advantage of the utility model automotive seat refrigeration system is: 1, native system directly picks out refrigerant from the high-pressure pipe of condenser, independent expansion valve makes the heat in the heat exchanger assembly evaporation absorption seat cushions of refrigerant in seat, so rate of cooling is fast, effective, seat surface is lowered the temperature rapidly, the seat of cool and comfortable is also arranged in the heat car in season; 2, seat temperature regulated at will automatically can be according to occupant's needs, regulate to keep the optimum temperature that is fit to; 3, native system utilizes the original air-conditioning refrigeration system of automobile, and just increasing heat exchanger assembly and a small amount of valve and pipeline in seat can realize, simple in structure, with low cost, easy for installation, do not understand the finite space that occupies in the car more yet, native system is particularly suitable for the auto use at 3～6 seats.
