Abstract
The invention relates to a cold cushion used for a fin heat pipe type thermocouple refrigeration vehicle. An aluminum sheet is clamped between two layers of thermal insulation cushions, the outer side of the aluminum sheet is jointed with flax laying cloth, and the inner side of a back cushion is connected with a lining plate. A heat radiating system comprising a fin heat pipe type heat radiator, a heat radiating fan, an inlet grid, a heat radiating hot-blast air hood and the like is arranged below a seat cushion. A thermocouple refrigeration sheet and a working medium in the fin heat pipe type heat radiator tightly contact. The thermocouple refrigeration sheet is connected with a cold guide unit and is tightly combined with the aluminum sheet. A three-position switch and the thermocouple refrigeration sheet are connected and electrified to work. In the invention, the heat is removed by the fin heat pipe type heat radiator, which reduces the temperature of the hot end of the thermocouple refrigeration sheet, and the temperature of the cold end of a thermocouple rapidly falls therewith; the cold guide unit sufficiently contacts with the aluminum sheet clamped between the thermal insulation cushions to conduct, and thereby, the temperature falls to form a cold end surface. The temperature of the cold cushion is far lower than that of a human body, and therefore, the low temperature can be kept for a long time.
Description
Technical field

Automobile-used cold pad of the present invention by the fin heat pipe type radiator heat-dissipation, has reduced the temperature in thermocouple refrigeration device hot junction, the temperature of thermocouple cold junction descends rapidly thereupon, fully contact, conduct with aluminium flake in the heat keeper by cool-guiding device, make it chilling temperature and descend, form the cold junction face.Cold pad temperature is lower than human body temperature more greatly.Therefore the present invention has the advantages that long-time low temperature keeps, exempt human body when high temperature in the car seat cushion overheated, take a seat the effect of the body illness of initiation for a long time.
Description of drawings
Fig. 1 is the principal section structural representation of cold cushion used for fin heat pipe type thermocouple refrigeration vehicle.
Among the figure: 1. fin heat pipe type radiator, 2. cooling fan, 3. cooling fan cover, 4. air intake grid, 5. thermocouple refrigerating sheet, 6. cool-guiding device, 7. fixed bin, 8. liner plate, 9. heat keeper, 10. aluminium flake, 11. Cigarette lighter adaptor unions, 12. three position switches, 13. hemp packing cloth.
The specific embodiment
Referring to Fig. 1, the low-temperature receiver of cold cushion used for fin heat pipe type thermocouple refrigeration vehicle is to adopt the powerful heat radiation of fin heat pipe, improves the temperature-difference refrigerating degree of depth of thermocouple, continue to offer cool-guiding device 6, make the cold pad aluminium flake 10 that cool-guiding device closely merges with it mutually carry out continuous cold conduction compensation.Cool-guiding device 6 is calculated by following formula with the actual cold of thermocouple refrigeration device 5 cold junctions:
Qo＝aabTcI-0.5I
2R-K(Th-Tc)
From formula as can be known the actual cold Qo of thermocouple refrigeration end equal the cold aabTcI that the thermocouple refrigeration end produces and deduct 1/2nd joule heat 0.5I
2R deducts by what Fu Liye heat conduction law was described again and heats the heat K (Th-Tc) that end conducts to refrigeration end by thermocouple.
Desire is accelerated the refrigerating speed of the automobile-used cold pad of fin heat pipe type thermocouple and is increased the temperature difference, must reduce by 1/2nd joule heat 0.5I
2R and heat end by thermocouple and conduct to the heat K (Th-Tc) of refrigeration end.After thermocouple refrigeration was true, resistance R in the formula and coefficient of thermal conductivity K value were determined.Just can select suitable current I to reduce by 1/2nd joule heat 0.5I
2R.
If reduce the heat K (Th-Tc) that conducts to refrigeration end by thermocouple refrigeration device hot junction.Thereby reduce the temperature T c that the temperature T h that heats end increases refrigeration end by the fin heat pipe type radiator, the cold of refrigeration end is conducted rather than accumulates in the refrigeration end of thermocouple rapidly by the aluminium flake in the cold pad by cool-guiding device.
The cold pad of the automobile-used cold pad heat insulation mechanism that adopts in the market, heat dispersion difference and can not carry out lower temperature again and compensate more can not play refrigeration.Pressing in the market provides a kind of the automobile-used cold pad that is lower than human body temperature can be provided lastingly, and a large amount of occupations and the non-professional driver interior hot disease that Long contact time high heat seat causes during summer high-temperature especially are more extensive.
Referring to Fig. 1, cold cushion used for fin heat pipe type thermocouple refrigeration vehicle, comprise back cushion partial sum cushion part, heat keeper 9 is through back cushion and cushion part, between the double-layer heat insulation pad 9 that constitutes cushion and a part of back cushion, accompany aluminium flake 10, aluminium flake 10 side engagement outside back cushion has hemp packing cloth 13, and back cushion part inboard is connected with liner plate 8, for contacting aspect with human body; Below cushion, be equipped with the cooling fan 2 of fin heat pipe type radiator 1 and its underpart, air intake grid 4 is housed on fin heat pipe type radiator 1, cooling fan cover 3 is housed below cooling fan 2, formed the cooling system of air intake air-out; Be provided with the working medium closed contact in thermocouple refrigerating sheet 5 and the fin heat pipe type radiator 1.The top connection cool-guiding device 6 of thermocouple refrigeration sheet 5, cool-guiding device 6 is bonded on the heat keeper 9 by fixed bin 7, combines closely with aluminium flake 10.On the frame of air intake air-out cooling system three position switch 12 is housed, it is connected energising work with thermocouple refrigeration sheet 5; In air intake air-out heat radiation is that Cigarette lighter adaptor union 11 is equipped with in the bottom of frame.The upper surface, seat is left opening, hemp packing cloth 13 is installed, and the lower end, seat is engaged with heat keeper 9 by seat cushion liner plate 8; There is upholstery border to decorate around the seat cushion.Cold pad is a flats.
The present invention has reduced the temperature in thermocouple refrigeration sheet 5 hot junctions significantly because the thermocouple refrigeration sheet adopts fin heat pipe radiator 1.The cold that thermocouple cold junction has been accelerated in cool-guiding device 6 and the conduction of aluminium flake 10 loose from, the aluminium flake 10 that makes it in the cold pad fully obtains low temp compensating, thus the present invention to have the refrigeration temperature difference big, the cooling characteristics that refrigerating speed is fast.
If need heat, then can adjust by three position switch 12, make the cold junction of cold pad be changed to the hot junction through energising work postposition after, be made for the heat pad and use.
As shown in Figure 1, behind Cigarette lighter adaptor union 10 connection vehicle powers, three position switch 12 pushes the work indicating positions.Direct current (DC) is by thermocouple refrigeration sheet 5, and the heating of the hot junction of thermocouple refrigeration sheet 5, cold junction freeze.The heat that send in the hot junction of thermocouple refrigeration sheet 5 heats the fin heat pipe type radiator 1 interior working medium of closed contact with it, and working medium heat absorption boiling is evaporated to the working substance steam with certain pressure and heat.These working substance steam rise rapidly in heat pipe and by tube wall heat are delivered on the radiating fin in uphill process, by forcing of cooling fan 2 distinguished and admirable generation among environment, realized heat radiation to thermocouple refrigeration sheet 5 hot junctions.The working substance steam that loses heat is condensed into worker quality liquid, and these worker quality liquids rely on gravity to be back to the working medium ware along tube wall.So move in circles and realized heat radiation thermocouple refrigeration sheet 5 hot junctions.Simultaneously, the cold of thermocouple refrigeration sheet 5 cold junctions is delivered to cool-guiding device 6 successively, and cool-guiding device 6 by 10 conduction of the aluminium flake in the heat keeper 9, has been realized the comprehensive refrigeration to cold pad to cold.
