Description

A kind of downflow type evaporator fin

Technical field

The present invention relates to a kind of downflow type evaporator fin, it is particularly well-suited to use on wind cooling refrigerator.

Background technology

In the modern life, refrigerator is increasingly becoming the necessary of life staying idle at home.And common refrigerator has direct cooling refrigerator and wind Two kinds of cold refrigerator etc..Direct cooling refrigerator is compared with wind cooling refrigerator：Direct cooling refrigerator structure is simple, easily manufactured；Rate of cooling is fast；Setting In the case that meter is rational in infrastructure, power consumption is than air cooling type refrigerator power saving and low price, but refrigerating chamber needs periodically to defrost；In case Temperature homogeneity is bad；Each chamber temperature can not individually be adjusted.And although wind cooling refrigerator is than direct cooling refrigerator complex structure, cost is also relatively Height, adopts forced convertion in case, leakage ratio of specific heat direct-cooling type is big, and therefore power consumption is big, but refrigerating speed is fast, temperature uniformly, can be from Dynamic defrosting, need not manually operate, the knob of temperature controller typically need not because of seasonal variations changing position.Refrigerating chamber and cold preservation Indoor temperature can be adjusted respectively by freezer temperature controller and cold room actuator, and use and maintenance is convenient, then air-cooled Refrigerator is increasingly becoming main product.And evaporator fin is as the important component part of wind cooling refrigerator, demand increases.

Evaporator fin is that one kind is connect by evaporation aluminum pipe, aluminum fin-stock, aluminum end plate, reservoir, process duct, copperhead, copper aluminum Head, the vaporizer of the composition such as heater strip reaches the purpose product of heat exchange by section of jurisdiction radiating, and common evaporation structure pushes away Enter formula（Angle-inserting type）Structure, drawing expansion type（Expanding）Structure etc..Push-in type structure is by vaporizer aluminium dish angled for disk Insert after pipe lamination in the fin fixing, then back bending, riveting end plate, group is welded into type；Drawing expansion type is to penetrate evaporation tube to set Fin in, evaporation tube and fin interporal lacuna coordinate, and are then inserted into the expander roll with swollen head in pipeline, then pass through to pull swollen Bar, drives swollen head, forces pipeline drawn expanded, makes pipeline form tight fit with fin, then bending, riveted, group are welded into type.

, because evaporation tube is coordinated for circumference with fin, heat exchange is more abundant for drawing expansion type evaporator fin, and processing technique is relatively Simply, but because more using piece number, working (machining) efficiency is not high, and solder joint is many compared with push-in type product, and the risk of leakage is larger, and In line structure is larger to the space occupancy of refrigerator；The contact surface of push-in type evaporator fin evaporation tube and fin is semicircle, Therefore heat exchange is not abundant, but its pipeline has certain angle of inclination, and in the case that internal volume is certain, space occupancy is little, solder joint Also lacking compared with drawing expansion type, processing technique is also relatively easy, using more in evaporator fin.

In view of the above problems, urgent need finds one kind and processes simple, low cost, and heat exchange is more abundant, space availability ratio is high Evaporator fin, then, a kind of new downflow type evaporator fin arises at the historic moment.It is similar with push-in type structure, but ratio Traditional evaporator fin structure has more advantage.

Content of the invention

The task of the present invention is to propose a kind of reduction power consumption, refrigeration more preferably, reduces a kind of downflow type wing of production cost Piece vaporizer

The task of the present invention be done in such a way that it include evaporating pipeline and fin it is characterised in that：On downflow type vaporizer Evaporation pipeline one end pipeline horizontal parallel, the other end of evaporation pipeline outwards skim after again level hereafter outwards skim again to being recycled to steaming Send out the root of pipeline, described evaporator tube from head end to root longitudinal passages from side be in splayed configuration structure, adjacent evaporation tube Road is transversely lower to misplace, and the evaporation pipeline after molding pushes in the fin fixing and end plate and is fixed on one by pipe expanding equipment Rise.It is connected equipped with reservoir and with the entrance mouth of pipe on the pipeline of described evaporation this one end of pipeline horizontal parallel, the root of evaporation pipeline Portion is connected with outlet.The fin hole installing evaporation pipeline is machined with fin, described fin hole parallel and adjacent to fin Hole is dislocated.The end plate bore installing evaporation pipeline is machined with end plate, described end plate bore parallel and adjacent to fin hole left Dextroposition, and end plate bore is consistent with flange direction with the relative position of corresponding fin hole.

The present invention has the effect that, 1, structure change after, flow direction in pipeline for the cold-producing medium be go downstream, more meet Principle of dynamics, can reduce the power requirement to compressor, reduce power consumption；2nd, pipeline interlocks, compact conformation, heat exchange More abundant, radiating is more uniform, and more preferably, case body temperature more equalizes refrigeration, effectively can shorten the available machine time, Reducing energy consumption；3rd, the coolant of this evaporator fin goes downstream, and easily portion forms frosting area under the vaporizers, but because evaporation Walk the high-temperature region near refrigerator under device, be conducive to defrost it is also possible to reduce heater strip power, reducing energy consumption；4th, end plate can picture Fin is equally directly processed and formed at one time by tube expansion operation, reduces special riveted operation, improve production efficiency, reduces and produce Cost.
