Description

Multifunction combined electronic refrigerating and heating apparatus

The utility model provides a kind of device of cold and hot wind.

At present electron cooling pyrogenicity device, only make single cooling and heating type case (refrigerator), perhaps single Cooling and heating blower.

This " multifunction combined electron cooling pyrogenicity device ", will dispel the heat Bunper assembly and refrigeration Bunper assembly are made multi-purpose assembling device.Need to form multi-purpose refrigeration and heating device easily by different purposes.This example is to be combined into " the cold-resistant clothing of cold and hot public attention helmet heatstroke prevention ".

Fig. 1 is a conductor refrigeration pyrogenicity element (3), and when DC current was passed through conductor refrigeration pyrogenicity element, the anodal end face of electric current (1) can produce refrigerating effect, and electric current negative pole end face (3) can the generation thermal effect.General thermal gradient energy reaches about 65 degrees centigrade, and when using the refrigeration operating mode, when hot-side temperature was 20 ℃, cold junction temperature can reach about-40 ℃.When being used in the pyrogenicity operating mode, when cold junction temperature was 15 ℃, the hot junction can reach about 70 ℃.

The structure of multifunction combined electron cooling pyrogenicity device as shown in Figure 2.(3) are conductor refrigeration pyrogenicity element among the figure, (4) be the heat radiation buffer, (5) be radiator, (6) be the refrigeration buffer, (7) be refrigeration heat converter, (8) be the adiabatic holding screw of element, (9) be the element fixed screw, (10) be the cold-hot machine fixed screw, (11) be glass fiber laminate (or tetrafluoroethene or nylon sheet) heat insulated supporter, (12) be cold scattering radiator combination holding screw, (13) for heating thermostat relay, (14) be the refrigeration temperature control relay, (15) be air intlet, (16) be heat radiation (cold) air outlet, (17) be refrigeration (heat) air outlet, (18) be blower motor, (19) for heat radiation (cold scattering) wind wheel (20) is refrigeration (heating) wind wheel, (21) motor fixed screw, (22) are supply socket, (23) be power switch, (24) be the cooling and warming selector switch, (25) are binding post, and (26) are the terminal plate fixed screw, (27) be new wind air inlet, (28) be new wind control gate, (29) are pulley, and (30) are nylon rope, (31) new wind gauge tap, (32) be the circulated air import, the circulated air filter that make for foamed plastics (33), (34) are the outlet of cold (heat) wind, (35) be cold air outlet joint, (36) are multifunction combined electron cooling pyrogenicity device complete machine.

Operation principle: behind power connection, blower fan (18) rotates, select operating mode by cooling and heating type selector switch (24), as: when selecting the refrigeration operating mode, then the end face (1) of conductor refrigeration pyrogenicity element (3) is a refrigeration face, and (2) are the pyrogenicity face, and air enters wind wheel (19) air blast cooling radiator (5) by (15), heat is taken away, discharged outdoor through heat radiation air outlet (16).Conductor refrigeration pyrogenicity element cold junction face (1) conducts to refrigeration heat converter (7) through refrigeration buffer (6), and the cold wind that makes is discharged through air outlet (34), through refrigeration air outlet joint (35) output cold wind.When reaching cryogenic temperature, by the outage of refrigeration temperature control relay, the work of stop conductor refrigeration when temperature raises, is connected power supply again, continues above-mentioned work, makes the cold wind of output meet the requirements of temperature (as 25 ℃).

Heating condition is pulled out to heating condition by selector switch, and operation principle is the same opposite, omits narration here.

Power supply can adopt totally-enclosed nickel-cadmium cell or automobile storage battery, can use rectifier (40) power supply in the occasion that AC power is arranged, as Fig. 3, exchange 220 volts of power supplys and be depressurized to 14 volts through transformer (37), again through diode rectifier (38), and after electric capacity (39) filtering, becoming 12 volts of dc sources, complete machine is called rectifier (40).

This example is by shown in Figure 4: be to be combined into " the cold-resistant clothing of helmet with powder supply for cooling and warm heatstroke prevention " (being called for short cold-warm clothing, as follows), be suitable for the operation of high-temperature operation or severe cold, motorcycle driving, car steering, patient's first aid, fire-fighting and army personnel and use.With motorcycle helmet (41) with make pleated neck cover (42) with the plastic-coated nylon cloth and link to each other, following termination collar, open a hole at the collar rear, install a joint (43) and be connected with flexible metal conduit (44), at this point, connected cold wind outlet connection (35), fill out in the cold-warm clothing (45) foamed plastics make heat insulation layer (46) again nexine reticulate folder body vest (49) (shown in Figure 5) by thin bamboo trunk (47) with nylon rope (48) woollen yarn knitting, lining is at the cold-warm clothing internal layer, can make the little part of cold (heat) wind flow to the helmet, and big portion is by folder body vest, the waist of flowing through is again discharged outside the clothing downwards.Reach that brains is refrigerant, the purpose of health cool and comfortable.And the air draft of radiator is born by exhaust duct (37).At cold-warm clothing waist one all internal layers the plastics magma (50) of interruption is set, when waist belt (51) fastening, cold air can circulate between plastics magma slit.Nickel-cadmium cell or enclosed accumulator (52) and electron cooling pyrogenicity device (36) are hung on the belt, connect electron cooling pyrogenicity device supply socket (54) by cable (53) again, battery can often be changed, and continues to use after charging, and charger can utilize rectifier (40) to charge.

Claims (2)

1, " the multifunction combined electron cooling pyrogenicity device " of cold and hot wind be provided, it is characterized in that having on this device a cold and hot selector switch [24], cold and hot thermostat relay [13] and [14], cooler of aluminum [5] and radiator [7], two-wheel wind wheel [19] and [20], hot blast is imported and exported, [16] reach [17], connector [35], circulated air import [32], circulated air filter [33], new wind gauge tap [31], power supply can or exchange through rectifier power supply with battery, and the example of this device is to be combined into " the cold-resistant clothing of cold and hot public attention helmet heatstroke prevention ".
