Description

Air-conditioner fin heat exchanger uniform flow field guiding device

Technical field

The utility model belongs to the air-condition heat exchanger technical field, is specifically related to a kind of air-conditioner fin heat exchanger uniform flow field guiding device.

Technical background

Air is used at air conditioner industry widely as the air-cooled air-conditioning product that cooling or heat medium source and finned heat exchanger carry out heat exchange, mainly be because of it has good heat exchange property, need not cooling water, and the installation site makes things convenient for.But the problem of non-uniform in present finned heat exchanger ubiquity process finned heat exchanger flow field in actual application, cause on the heat exchange area windward side as shown 1 and to illustrate wind speed shown in 2 inhomogeneous, cause the heat exchanger heat exchange inhomogeneous, heat exchange efficiency descends, and has caused the air-cooled side heat exchange area of air-conditioning system can not fully effectively utilize with systematic energy efficiency ratio and has descended.

Summary of the invention

The purpose of this utility model provides a kind of air-conditioner fin heat exchanger uniform flow field guiding device, to overcome the above-mentioned shortcoming of prior art.

The purpose of this utility model is achieved by the following technical solution: a kind of air-conditioner fin heat exchanger uniform flow field guiding device, it is characterized in that guiding device is single individual deflector or the assembly that is processed into straight line bending type or straight line board-type shape or annular trumpet type or annular straight barrel type by engineering plastics or sheet metal structural spare, described bending type deflector is that top is the deflector that straight plate bottom outwards bends several or arc; Described assembly is meant that the assembly that plural deflector is combined into different structure combines with finned heat exchanger.

Owing in the enclosure space of between common air-conditioning finned heat exchanger and other structural members, being formed guiding device has been installed, distribute through the air-flow that finned heat exchanger ventilates by the guiding device adjustment, make the finned heat exchanger face velocity be in more uniform state, guarantee that the finned heat exchanger heat exchange is abundant, make system be in the high efficient heat exchanging state all the time.

The beneficial effects of the utility model are: solved the inhomogeneous state in finned heat exchanger flow field, realized the high efficient heat exchanging and the reliability of system.
