Description
Technical field
The present invention relates to a kind of heat exchangers, more particularly to one kind is for each fields such as air-conditioning, freezing and refrigeration, automobile and transports
Heat exchanger.
Background technique
The efficiency of system requires increasingly to improve, and has increasing need for the heat exchanger of higher performance.And for heat exchanger as steaming
When sending out device, since heat exchange temperature is lower than environment temperature, there is condensed water, if cannot exhaust as early as possible, will form and connect in surface
Water bridge or frosting, these can all substantially reduce the exchange capability of heat of heat exchanger.
Fig. 1 shows a kind of flat tube 10 of heat exchanger in the prior art and the stereoscopic schematic diagram of fin 20；Fig. 2 shows existing
The flat tube 10 of one of technology heat exchanger and the plan view of fin 20；Fig. 3 shows the flat tube 10 and wing of the heat exchanger in Fig. 2
The partial enlargement diagram of piece 20.
As shown in Figure 1 to Figure 3, existing micro-channel heat exchanger is used as evaporator, mostly uses header horizontal positioned,
The arrangement that flat tube 10 is placed vertically, exactly in order to condensed water can be made to flow out as early as possible along the flat tube 10 placed vertically.
It is in general vertical relation between fin 20 and flat tube 10 due to the relationship between flat tube 10 and fin 20, so fin 20 is practical
On be approximate horizontal placement in such arrangement.Since the main heat exchange area of heat exchanger and environment heat exchange is in fin
On 20, that is to say, that fin 20 is the main generating region of condensed water.And the fin 20 of approximate horizontal placement becomes draining and asks
The biggest obstacle of topic.
As shown in Figure 1 to Figure 3, in the prior art, in the join domain of fin 20 and flat tube 10, condensed water 30 can not flow
Under, can only along the direction of wind, heat exchanger leeward under the stream of flat tube 10 (as shown in Figure 1).
Fig. 1 to it is shown in Fig. 3 in the prior art, condensed water must flow through the width of entire flat tube 10 along the direction of wind
Degree, can cause the drainage efficiency of heat exchanger low under the leeward side stream along flat tube 10, reduce the heat exchange effect of heat exchanger
Rate.
