Abstract

The utility model provides a forced air cooling refrigerator evaporimeter, the utility model provides a, a forced air cooling refrigerator evaporimeter, it includes the evaporator coil, the fin, the fin of having arranged on the evaporator coil leaves the space between, and the space is Y shape, and the fin above the evaporator coil is arranged density and is greater than the fin range density in the evaporator coil below. The chain for stripping the bark has a reasonable structure, the utility model discloses a coil pipe fin is in the shortcoming to department's of being difficult to frost about evaporimeter upper portion, evaporator coil side -finned arrange be Y font passageway on the coil pipe, do not install the fin on the evaporator coil in the passageway, convenient below electric heating wire's heat passes through upper left side, the upper right side and the liquid storage pot department that passageway (the frost layer in the passageway does not basically stop) passed to the evaporimeter to make the evaporimeter frost tend to synchronous, with the reductionization frost time, thereby be favorable to energy -conservation.

Description

A kind of air cooling refrigerator evaporator

Technical field:

The utility model relates to refrigerator, the air cooling refrigerator evaporator particularly a kind of refrigerator used.

Background technology:

Patent in wind cooling refrigerator defrost can be divided into several large class substantially: defrosting control method class, defrost mode of heating class, evaporation structure improve class etc.

Patent: CN104482716A, " 2015.04.01 the defrosting control method of refrigerator and refrigerator ", a kind of defrosting control method and refrigerator of refrigerator are proposed, according to the defrosting control method of refrigerator of the invention process, defrost periods can be adjusted intelligently and temperature is exited in defrost, not only can ensure defrost effect, energy-conservation object can also be reached, promote the market competitiveness of refrigerator.This patent is the angle from defrosting control method.

Patent: CN104390415A, 015.03.04, " a kind of wind cooling refrigerator defrosting system and control method thereof, wind cooling refrigerator ", disclose a kind of wind cooling refrigerator defrosting system and control method thereof, wind cooling refrigerator, comprise freezer evaporator, freezer evaporator is provided with refrigerating chamber defrost assembly, refrigerating chamber defrost assembly of the present invention comprises the first defrost parts being located at freezer evaporator bottom part down and the second defrost parts be located on freezer evaporator sidewall, freezer evaporator assembly can heat the bottom of freezer evaporator and sidewall respectively respectively, entirety on freezer evaporator is heated more even, avoid and occur the phenomenon that local frost cannot be melted in defrost process.This patent is the angle from defrosting control method.

Patent: CN202254504U, 2012.05.30 " fin evaporator for refrigerator ", disclose a kind of layout structure of fin evaporator of air-cooled refrigerator, it is less that the utility model presents upper end inter fin space in the layout of whole evaporimeter, the permutation and combination method that lower end inter fin space is become estranged relatively, be conducive to the smooth circulation of air, improve the heat exchanger effectiveness of evaporator fin.This patent is the angle from evaporation structure form.

From existing patent, all there is different effects in actual applications.From found patent, not do not consider in line with the synchronism of whole evaporimeter defrost.And the phenomenon that electrical heating defrost power is excessive or power consumption is too large in wind cooling refrigerator easily occurs, this causes because defrost is uneven, a part defrost is complete and another part also exists a large amount of frosts, the non-constant of synchronism of whole evaporimeter defrost often.

Summary of the invention:

The purpose of this utility model is to provide a kind of air cooling refrigerator evaporator rational in infrastructure, and this air cooling refrigerator evaporator effectively can solve evaporimeter defrost non-uniform phenomenon: solve the upper left side of evaporimeter, upper right side and evaporator place, top problem not thorough with the pipeline defrost contacted with it.

The technical solution of the utility model is, a kind of air cooling refrigerator evaporator, it comprises evaporator coil, fin, it is characterized in that: on evaporator coil, be placed with fin, leave space between fin, space is Y-shaped, and the fin arrangement density above evaporator coil is greater than the fin arrangement density below evaporator coil.

The utility model is rational in infrastructure, coil pipe fin of the present utility model is being difficult to the shortcoming of defrost for left and right place, evaporimeter top, the outer fin of evaporator coil be arranged on coil pipe in Y-shaped passage, evaporator coil in passage does not install fin, the heat of convenient below electrical heating wire passes to the upper left side of evaporimeter, upper right side and fluid reservoir place by passage (frost layer in passage does not stop substantially), thus make evaporimeter defrost be tending towards synchronous, to reduce the defrost time, thus be conducive to energy-conservation.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention:

Describe embodiment in detail by reference to the accompanying drawings,

A kind of air cooling refrigerator evaporator, it comprises evaporator coil 1, fin 2, evaporator coil is placed with fin, leave space 5 between fin, space is Y-shaped, and the fin arrangement density above evaporator coil is greater than the fin arrangement density below evaporator coil.

Because the heat of defrosting is mainly through hot-air free convection and radiation direction transmit, the utility model evaporator surface fin does not cover evaporator coil completely, but present a Y-shaped passage at evaporator coil, evaporator coil in passage does not install fin, thus make that the radiations heat energy of electric heating tube 4 below evaporimeter is substantially unobstructed passes to the upper left side of evaporimeter, upper right side and fluid reservoir 3 place by passage, thus make defrost process longitudinally synchronous; And the fin on whole evaporator coil adopts the method for upper tightly lower sparse to arrange.

Claims

1. an air cooling refrigerator evaporator, it comprises evaporator coil, fin, it is characterized in that: on evaporator coil, be placed with fin, leave space between fin, space is Y-shaped, and the fin arrangement density above evaporator coil is greater than the fin arrangement density below evaporator coil.
