Abstract

The utility model discloses a spiral flat heat exchange of heat pipe for refrigerator freezer, including import pipe, outlet pipe, flat pipe and fin, the decurrent structure of spiral is made in flat pipe turn, and import pipe and outlet pipe are connected respectively to the both ends of flat pipe, and the flat tub of downward spiral space that forms of spiral vertically is equipped with two at least perpendicular decurrent corrugated fin, wherein, and the corrugated fin of setting below the corrugated fin's of top the pitch of waves is less than it the pitch of waves. This a spiral flat heat exchange of heat pipe for refrigerator freezer space volume utilization ratio is high, and the refrigerant distribution is even, and the drainage is convenient.

Description

A kind of spiral flat pipe heat exchanger for refrigerator

Technical field：

This utility model is related to a kind of heat exchanger, is especially a kind of spiral flat pipe heat exchanger for refrigerator.

Background technology：

The heat exchanger being currently used for refrigerator is typically pipe wing, adopts header, flat tube, fin, aluminum structure more Base integral braze-welded form, wherein fin is evenly distributed between parallel stream flat pipe to increase heat exchange area.This structure Heat exchanger there is the shortcomings of space shared by profile is big, and coolant distribution is uneven, draining is difficult.

Utility model content：

Technical problem to be solved in the utility model is to provide a kind of spatial volume utilization rate height, and coolant is evenly distributed, Draining is conveniently used for the spiral flat pipe heat exchanger of refrigerator.

Technical solution of the present utility model is to provide a kind of spiral flat pipe heat exchanger for refrigerator, bag Include inlet tube, outlet, flat tube and fin, described flat tube is bent into the structure of downward spiral, the two ends of flat tube connect respectively into Mouth pipe and outlet, the spiral space that flat tube downward spiral is formed longitudinally is provided with least two corrugated fins vertically downward, Wherein, the pitch of waves of the corrugated fin being disposed over is less than the pitch of waves of corrugated fin below.

Using after above structure, compared with prior art, this utility model has advantages below：Flat tube is bent into spiral Shape, two ends connect inlet tube and outlet and form a framework, after the completion of load fin, the fin pitch of waves is up-narrow and down-wide, vertical point Inside spiral space, from overhead stream to bottom, such fin is distributed both increasing heat radiation areas to wind to cloth, is conducive to wind direction stream Dynamic, improve radiating efficiency, the effect of the reinforcement of fixing flat tube can be played again；This structure also optimizes welding manner, Gu Surely complete the laggard soldering oven of shaping and carry out integral solder, then weldering is attached the welding of pipe by hand, reduce solder joint, so make Overall structure becomes simple, occupies little space, improve product quality, and coolant is evenly distributed.

Preferably, described flat tube be bent into the single coil configuration of downward spiral, double-spiral structure, in many helical structures Any one.

Further, the spiral space that flat tube downward spiral is formed longitudinally is provided with corrugated fin and lower corrugated fin, Wherein, the pitch of waves of upper corrugated fin is less than the pitch of waves of lower corrugated fin.

Brief description：

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

Fig. 2 is the structural representation of upper corrugated fin.

Specific embodiment：

The utility model is described in further detail with reference to the accompanying drawings and detailed description：

As shown in figure 1, a kind of spiral flat pipe heat exchanger for refrigerator, including inlet tube 1, outlet 2, flat tube 3 and fin, described flat tube 1 is bent into the structure of downward spiral, and the two ends of flat tube connect inlet tube 1 and outlet 2, flat tube respectively The spiral space that downward spiral is formed longitudinally is provided with corrugated fin 4 and lower corrugated fin 5, wherein, the ripple of upper corrugated fin Away from the pitch of waves less than lower corrugated fin.In addition, flat tube is bent into the single coil configuration of downward spiral, double-spiral structure, many spirals Any one in structure, certainly, for heat exchange amount, the heat exchange performance of double-spiral structure and many helical structures can be more preferably.

Below only this utility model preferred embodiment is described, but is not to be construed as the limit to claim System.Every equivalent structure being done using this utility model description and accompanying drawing content or equivalent flow conversion, are included in this Within the scope of patent protection of utility model.
