Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is further elaborated:
Embodiment
A kind of automatic defrosting evaporator fin structure is as shown in Fig. 1,2,3,4,5, the present embodiment comprises 12 fin plates 1 and runs through the coiled pipe 2 of fin plate 1, the side of fin plate 1 is protruded and is provided with 6 radiated ribs 4, and described radiated rib 4 is vertically arranged between laterally adjacent coiled pipe 2; The heater of the present embodiment comprises power supply 5, wire 7 and heating wire 8, radiated rib 4 inside arranged on same fin plate 1 has heating wire 8 longitudinally to run through, be end to endly together in series, heating wire 8 is connected on power supply 5 by wire 7, and described power supply 5 is connected with controller 6.
Described controller 6 comprises temperature detector 9, comparator 10, amplifier 11 and relay 13, the output of temperature detector 9 is connected with the input of comparator 10, the output of comparator 10 is connected with the input of amplifier 11, the output of amplifier 11 is connected with the coil of relay 13, and the normally open contact of relay 13 is connected in the loop that heating wire 8 is connected with power supply 5.
The base plate 16 of support fin plate 1 tilts, and inboard high, outside is low, left side is high, and right side is low, and base plate 16 peak of the present embodiment is inside left side, base plate 16 minimum point is outside right side, and base plate 16 is along outer side edges being provided with guiding gutter 3, and the outlet of guiding gutter 3 is positioned at the minimum point of base plate 16.
Be provided with 6 radiated ribs 4 vertically arranged between laterally adjacent coiled pipe 2, between radiated rib 4, define gutter channel 14.
