Abstract

The utility model belongs to the technical field of refrigeration and air conditioning, in particular to a heat exchanger for the refrigeration and air conditioning, wherein a radiating fin of the heat exchanger is fixed on a heat exchange tube which is made from a composite aluminum tube or an aluminum tube. According to the technical scheme, the composite aluminum tube or the aluminum tube adopted by the utility model can replace copper tubes, and the aluminum tube type heat exchanger improves the heat exchange performance greatly compared with a copper tube heat exchanger, and has smallest device heat exchange effect decrease and stable heat exchange performance after being operated by a heat pump in winter. Therefore, the utility model not only can reduce the cost of manufactures, but also reduces the use cost of clients.

Description

A kind of cooling air conditioner heat exchanger

Technical field

The utility model belongs to the refrigeration and air-conditioning technical field, is specifically related to a kind of cooling air conditioner heat exchanger.

Background technology

The material of existing air-conditioner heat exchanger is generally the copper tube and fin formula, and adopt the mechanical plumber's skill that rises to make the flange of copper pipe and fin realize closely cooperating, the heat transfer resistance of this heat exchanger is bigger, the heat exchange poor effect, especially the heat exchange effect is poorer behind process operation of heat pump in winter, and production cost is higher, and is inconsistent with present energy conservation and environment protection.

Summary of the invention

The purpose of this utility model provides a kind of cooling air conditioner heat exchanger, and its heat exchange is respond well and cost is low.

For achieving the above object, the utility model has adopted following technical scheme: a kind of cooling air conditioner heat exchanger, radiating fin are fixedly installed on the heat exchanger tube of being made by compound aluminum pipe or aluminum pipe.

As shown from the above technical solution, the utility model adopts compound aluminum pipe or aluminum pipe to replace copper pipe, and this aluminum pipe formula heat exchanger is compared with copper pipe heat exchanger, heat exchange property has obtained significantly improving, behind process operation of heat pump in winter, the heat exchange effect decay of equipment is littler, and heat exchange property is stable.From the above, use of the present utility model had both reduced the cost of manufacturer, had reduced client's cost of use again.

Description of drawings

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

Fig. 2 is the left view of Fig. 1.

The specific embodiment

As shown in Figure 1, 2, a kind of cooling air conditioner heat exchanger, radiating fin 30 are fixedly installed on the heat exchanger tube of being made by compound aluminum pipe 10 or aluminum pipe 20.

As preferred version of the present utility model, described radiating fin 30 is compound aluminium flake.

As another kind of preferred version of the present utility model, described heat exchanger tube is compound aluminum pipe 10, and radiating fin 30 is an aluminium flake.

The utility model uses compound aluminum pipe 10 or aluminum pipe 20 to replace traditional copper pipe, to directly bring following advantage: one to heat exchanger, because the copper pipe of traditional heat exchangers is different with the expansion and contraction that expands with heat and contract with cold between the aluminium fin, therefore produce the gap between copper pipe and the aluminium fin easily because of expanding with heat and contract with cold, thereby reduced the heat transfer property of heat exchanger, and heat-transfer pipe and fin are aluminum material in the utility model, so reduced the different and heat transfer coefficient difference that caused of material greatly, improved the heat transfer property of product; Its two, the price of compound aluminum pipe 10 or aluminum pipe 20 is lower than copper pipe, therefore application of the present utility model has not only reduced the metal consumptive material, has also reduced the production cost of heat exchanger; Its three, aluminum pipe 20 is more flexible than copper pipe, so the high tenacity of aluminum pipe 20 makes the utility model be convenient to more install and make.

It is multiple that fin the mode on compound aluminum pipe 10 or the aluminum pipe 20 of being fixed on is had, and as preferred version of the present utility model, described compound aluminium flake is fixedly installed on compound aluminum pipe 10 or the aluminum pipe 20 by the pipe that rises; Perhaps aluminium flake is fixedly installed on the compound aluminum pipe 10 by the pipe that rises.

The said fixing mode has adopted traditional plumber's skill that rises, and therefore can continue to use existing device fabrication, under the situation that makes existing device accomplish to make the best use of everything, has correspondingly improved competitiveness of the present utility model.

As another kind of preferred version of the present utility model, described compound aluminium flake is weldingly fixed on compound aluminum pipe 10 or the aluminum pipe 20; Perhaps aluminium flake is weldingly fixed on the compound aluminum pipe 10.

Adopt welding manner that fin is fixed on compound aluminum pipe 10 or the aluminum pipe 20, also promptly make fin and compound aluminum pipe 10 or aluminum pipe 20 connect as one, thereby fin that the plumber's skill of having avoided rising is brought and the fit clearance between compound aluminum pipe 10 or the aluminum pipe 20 and the high heat transfer thermal resistance that causes, can significantly improve the heat transfer property between fin and compound aluminum pipe 10 or the aluminum pipe 20, also greatly reduce the heat exchange property decay that brings because of heat pump cycle simultaneously.

Welding also has multiple mode to select, and such as methods such as employing inert gas-shielded arc weldings, as the further preferred version of the utility model, described compound aluminium flake is weldingly fixed on compound aluminum pipe 10 or the aluminum pipe 20 by the continous way aluminium soldering; Perhaps aluminium flake is weldingly fixed on the compound aluminum pipe 10 by the continous way aluminium soldering.

Described continous way aluminium soldering can realize by the automatic welding of continous way aluminum brazing furnace, its welding quality height, the comparatively even and technical maturity of heating, and this kind welding manner can not stay fin and heat exchanger tube ground, slit to be connected as a whole, its welding effect can reduce the heat transfer resistance of heat exchanger greatly, and is suitable for producing in enormous quantities manufacturing.

Described compound aluminum pipe 10 is by internal layer and outer the composition, and compound aluminium flake or aluminium flake are fixedly installed on the skin of compound aluminum pipe 10.

Compound aluminum pipe 10 has not only further improved heat transfer property of the present utility model, and has reduced production cost, has also reduced operating cost simultaneously.

As shown in Figure 2, described compound aluminum pipe 10 or aluminum pipe 20 can only be arranged a row, and many rows also can be arranged in parallel; It can vertically be arranged, and also can obliquely arrange.
