Detailed description of the invention:
Engage specific embodiments and the drawings below to further illustrate the utility model.
Embodiment 1:
As shown in Figure 1-Figure 3, described in the utility model is a kind of automotive seat a/c system, this automotive seat a/c system comprises casing 1, case lid 11, be built in the refrigerating unit 2 in casing 1 and magnetic force liquor pump 3, and be communicated with liquid coil pipe 4 with magnetic force liquor pump 3, refrigerating unit 2 is by minisize dc compressor 21, compressor drive 22, condenser 23, condensation fan 24, evaporator 25 and capillary tub 26 form, described evaporator 25 is double pipe heat exchanger, in it, the two ends of pipe are communicated with the refrigerant tubing of refrigerating unit 2, the two ends of its outer tube are communicated with described liquid coil pipe 4 and magnetic force liquor pump 3, described liquid coil pipe 4 also has the heat exchange coil 41 be arranged in automotive seat.
Specifically; in the present embodiment; evaporator 25 is arranged in the side of casing 11; opposite side arranged cold condenser 23 and condensation fan 24; midway location arranges minisize dc compressor 21; compressor drive 22 is arranged in evaporator 25 side, the cold of evaporator 25 can be utilized to reduce the temperature of actuator 3, to protect actuator 3.Casing 1, case lid 11 leave grid mouth 12 at condenser 23 and condensation fan 24 air inlet/outlet place respectively, in order to condenser 24 dispel the heat necessary air flowing.
The interior pipe of double pipe heat exchanger is arranged in the refrigerant loop of refrigerating unit, and the outer tube of described liquid coil pipe 4, magnetic force liquor pump 3 and double pipe heat exchanger forms a heat-exchanging loop, is heat exchanging liquid in this heat-exchanging loop with Glycol Mixture; Select Glycol Mixture, while can guaranteeing there is good exchange capability of heat, at low temperatures (as lower than-15 degree) be also unlikely to icing.For reaching better interchange of heat, Glycol Mixture flow direction is set to contrary with the refrigerant flow direction of refrigerating unit 2.
When refrigerating unit 2 is freezed, absorbed heat in pipe in telescopic evaporator 26 after condensation, throttling by the refrigerant compressed, evaporate, interchange of heat is carried out with the heat exchanging liquid in outer tube, heat exchanging liquid heat release, temperature reduces, at the flows by action of magnetic force liquor pump 3 to the heat exchange coil 41 being arranged in automotive seat, interchange of heat is carried out with seat and interior air thereof, seat and ambient air temperature are reduced, flow back to outer tube again and form cycle heat exchange, thus reach automobile seat temperature reduced, take feel more comfortable, nice and cool.
In the utility model, described minisize dc compressor is the micro-compressor of external diameter about 50mm.Because car utilizing space little, refrigerating unit is sufficiently small and exquisite.Adopt double pipe heat exchanger as evaporator 25, the volume of evaporator 25 can do smaller, and because of liquid-cooled evaporator heat exchange efficiency high.Namely the interface of evaporator 25 divides fluidic interface and refrigerant interface, and minisize dc compressor 21, the capillary tub 26 of refrigerant interface and refrigerating unit are connected; Magnetic-type liquor pump 3 is installed at fluidic interface one place, locates afterwards equally to pass casing 1 with another.Pass being connected with the liquid coil pipe 4 arranged under seat of the fluidic interface sealing outside casing 1, the circulation of liquid part is achieved.
For improving the heat transfer capability of liquid coil pipe 4, the material of liquid coil pipe 4 is preferred, uses polyethylene pipe.In the utility model, the source of electric power, can direct-connected storage battery from automobile storage battery, also connects by Cigarette lighter, very convenient.
Embodiment 2:
As shown in Figure 4, in the present embodiment, four-way change-over valve 27 is connected with in the import and export pipeline section of the minisize dc compressor 21 of described refrigerating unit 2, by conversion four-way change-over valve 27, the mode of operation of refrigerating unit 2 can be changed, be divided into refrigeration mode and heating mode, correspondingly, refrigeration or heating effect are produced to automotive seat, makes automotive seat a/c system realize both cooling and heating.When refrigerating unit heats, suitably can heighten the flow of liquor pump, to guarantee the effect of interchange of heat.
The utility model automotive seat a/c system possesses automotive seat air-conditioning institute completely must be low in energy consumption, the advantages such as cooling and warming speed is fast, and overall volume is little, can directly independently install additional, without the need to changing former fare road, power with Cigarette lighter original on car or 12DC power interface, power source safe ready.
Simple embodiment of the present utility model shown in above-described embodiment and accompanying drawing; those skilled in the art can when not departing from the utility model thought; various modifications or change are made to above-described embodiment; thus protection domain of the present utility model not limit by above-described embodiment, and should be the maximum range of the inventive features that claims are mentioned.
