The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
Shown in Fig. 2-4, the auxiliary heating of electricity of the present invention is fixedly installed on the finned evaporator structure, described evaporation structure comprises fin and runs through the refrigerant conduit 12 of fin, wherein said refrigerant conduit is a high frequency aluminium welded tube, in order to guarantee that refrigerant conduit 12 has good thermal diffusivity with combining of fin, what adopt is that modes such as the mode of welding or expand tube combine both, the end of refrigerant conduit 12 was communicated with refrigerant conduit 12 adjacent or that press graded interval by " U " communicating pipe, simultaneously, the import of refrigerant conduit and outlet are connected with refrigerant flow respectively.Fin of the present invention comprises the body 110 of rectangle laminated structure and has been formed extended at both sides extension 111 at body 110 1 ends to a side, offer the through hole that is complementary with described refrigerant conduit 12 on the described body 110, offer two parallel exhausting holes on the general described body 110, two row's refrigerant conduits 12 to be set to increase its radiating efficiency; Offer through hole on the described extension 111, the shape of described through hole and electric heater unit is complementary, described electric heater unit 120 is a strip electrically heated rod structure, its cross section is circle or rectangular configuration, and described electrically heated rod can adopt modes such as low-temperature welding or interference fit with the mode of fixedlying connected of fin.
Certainly, described extension also can be formed on the centre of fin body, and integral fins is the convex shape structure, on the extension that protrudes in the middle of electric heater unit is fixedly installed on.
Further, described electric heater unit one end is set with binding post 112, to simplify being electrically connected between electric heater unit and power supply and the PCB, described electrically heated rod and binding post be for fixedly to be electrically connected, and guarantee the insulation with fin, and described binding post 112 can be fixedly connected with fin, certainly, it also can be fixedlyed connected with the fixed support of radiator.
With the binding post 112 corresponding other ends end fixation clamp 113 of electric heater unit is being set, described and fixation clamp 113 is fixedly installed on the fin or is fixedly installed on the fixed support of evaporimeter, described fixation clamp 113 is fixed the end of electric heater unit, prevents that it is connected with the fin disengaging.
Certainly, described fin can be rectangular sheet shape structure, offers the parallel through hole that is provided with of three rows on it, the corresponding setting with electrically heated rod of described upper strata through hole, middle level through hole and lower floor through hole and the corresponding setting of refrigerant conduit.
What be readily appreciated that is also electrically heated rod to be fixedly installed on the intermediate layer or the lower floor of three exhausting holes.Further, offer two exhausting holes on the described fin, the refrigerant conduit is with in electrically heated rod is fixedly installed on corresponding through hole alternately.
In concrete assembling process, earlier with electric heater unit and refrigerant conduit with insert in the fin of evaporimeter accordingly, two ends with electric heater unit prevent fixedly that respectively at fin itself and fin break away from, and prevent evaporimeter that the soldier is communicated with refrigerant flow than the refrigerant conduit on the fixed support then then.In concrete work, when needs heat, the refrigerant that becomes high-temperature high-pressure state through compressor compresses can dispel the heat to the outside in evaporimeter, and when flowing through expansion valve, significantly reduce its temperature and pressure, this low temperature, low pressure refrigerant can absorb heat when flowing through condenser then, flow back in the compressor again at last.Outdoor lower, when heating effect is undesirable, in compressor operating, the PCB follow procedure can start the auxiliary heating of electricity, because electric auxiliary heating device of the present invention is arranged in the fin of evaporimeter, its heat that is produced when work passes to fin rapidly, because the thermal conductive resin of fin and conductivity of heat, under the acting in conjunction of refrigerant heat radiation and electric auxiliary heating device heat radiation, make the temperature of evaporator fin raise rapidly, like this when fin is crossed in wind, raise through the heat exchange gas flow temperature, improved the heating performance of product.
In sum, electricity of the present invention is assisted heating arrangement, and electric heater unit is fixedly installed on the evaporator fin, and described evaporator fin is provided with difform through hole, be respectively applied for and fixedly install electric heater unit and refrigerant conduit, make evaporimeter and electrical heating one.Utilize the fin heat radiation, improve electrical heating efficiency, reduce heat waste simultaneously.Reduce installation difficulty, reduced windage simultaneously, improved the efficient of pressure fan.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
