Therefore; The defrosting heating tube is installed in some refrigeration plant on some market, and this defrosting heating tube generally is located at the bottom of evaporimeter, i.e. position between evaporimeter and the drip tray; But there is following defective in this structure: at first; Heating tube is located at base of evaporator, too far causes thermal loss apart from evaporator coil, and the defrost effect is bad.Secondly, this structure often need reach the defrost purpose through increasing the defrost time or increasing heating tube power, and energy consumption is bigger, causes energy waste.At last,, further aggravate the temperature fluctuation of refrigeration plant, the performance of refrigeration plant is reduced because the defrost effect is bad.
Summary of the invention
The technical problem that the present invention will solve provides a kind of evaporimeter of defrost better effects if.
In order to solve the problems of the technologies described above, the technological means that the present invention adopted is:
A kind of finned evaporator; Comprise evaporator coil, be socketed in the some fins on the evaporator coil, the side plate of being located at the evaporimeter two ends, the drip tray of being located at base of evaporator, first heating tube and second heating tube; It is characterized in that; Said first heating tube is located at base of evaporator, drip tray top, and said secondary heater is located at the evaporimeter middle part and is run through evaporator fin.
Said drip tray is connected with drainpipe, is provided with the sheet metal that is connected with first heating tube in the drainpipe.
Said fin is provided with the fin holddown groove in order to fixing second heating tube.
Said side plate is provided with in order to first holddown groove of fixing first heating tube with in order to fix second holddown groove of second heating tube.
Said first heating tube is coil-like, and first heating tube is fixed through first holddown groove on the side plate, second holddown groove and first fixed head.
The said first fixed head two ends are the arc-shaped bend structure.
Said second heating tube is the U-shaped structure and fixes through fin holddown groove, first holddown groove and second fixed head.
One end of said second fixed head is the arc-shaped bend structure.
Compared with prior art, the present invention has following beneficial effect:
The first, the present invention is provided with two heating tubes, i.e. first heating tube and second heating tube, and wherein second heating tube is located at the evaporimeter medium position; More, reduced thermal loss, had better defrost effect near evaporator coil; Reduced energy consumption simultaneously, more economized on resources.
The second, first heating tube of the present invention is located at base of evaporator, drip tray top, and this heating tube can directly melt on the one hand falls residual ice on the drip tray, on the other hand, can replenish the heat of second heating tube, quickens the thawing of frost layer on the evaporimeter.
Three, the present invention is provided with drainpipe on drip tray, is provided with sheet metal in the drainpipe, and second heating tube melts the residual ice in the drainpipe through heat being conducted to sheet metal, prevents that residual ice from stopping up drainpipe.
Four, the present invention is simple in structure, is convenient to install, and is easy to make, and can be widely used in commercial production.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further explain.
To shown in Figure 9, finned evaporator of the present invention comprises evaporator coil 1, some fins 2, drip tray 4, first heating tube 5 and second heating tube 6 and is located at the side plate 3 at evaporimeter two ends like Fig. 1.
The present invention does not have strict the qualification to the interval between fin 2 quantity and the fin 2, can combine art technology general knowledge and confirm the gap size between fin 2 quantity and the fin 2 according to the evaporimeter size.As shown in Figure 7, said fin 2 is provided with some installing holes, and fin 2 is socketed on the evaporator coil 1 through installing hole; In addition; Also be provided with two fin holddown grooves 21 on the fin 2, this fin holddown groove 21 extends to fin 2 medium positions, uses for second heating tube 6 and passes.
Said drip tray 4 is located at evaporimeter below, is fixedly installed on the side plate 3 at evaporimeter two ends the distance of maintenance 15-25mm usually between drip tray 4 and fin 2 bottoms through screw or welding or other fixed forms.As shown in Figure 2, be provided with some installing holes on the said side plate 3 equally in order to installation evaporator coil 1, the installing hole quantity on fin 2 and the side plate 3 is decided according to evaporation structure, and in the present embodiment, said evaporimeter is the two-stage coil arrangement.
In addition; Also be provided with first holddown groove 52 and two second holddown grooves 62 on the side plate 3 in order to fixing second heating tube 6 in order to fixing first heating tube 5; Said first holddown groove 52 is located at the bottom of side plate 3, and said second holddown groove 62 extends to the medium position of side plate 3 so that second heating tube 6 is fixed in the evaporimeter middle part.It is said that first holddown groove 52 of the present invention, second holddown groove 62 and fin holddown groove 21 quantity are not limited to preamble; Holddown groove (comprising first holddown groove 52, second holddown groove 62 and fin holddown groove 21) quantity is decided according to the shape of first heating tube 5 and second heating tube 6; Such as; As shown in Figure 3, second heating tube 6 in the present embodiment is the U-shaped structure, therefore needs two fin holddown grooves 21 and two second holddown grooves 62 to fix.Said second heating tube 6 run through fin 2 and be placed in fin holddown groove 21 and second holddown groove 62 in make second heating tube 6 be positioned at the evaporimeter medium position; Simultaneously; For further fixing second heating tube 6; It is strip aluminium sheet structure that present embodiment also is provided with second fixed head, 61, the second fixed heads 61, and an end of second fixed head 61 is the arc-shaped bend shape; The other end that this arc-shaped bend structure catches on evaporator coil 1, the second fixed head 61 passes from the below of second heating tube 6 and bends by external force and blocks the evaporator coil 1 that stretches out from side plate 3 sides.Certainly, a kind of mode of this just fixing second heating tube 6, the present invention can also fix second heating tube 6 and other device ways of connecting through adopting wire.
