Go out easily to occur the phenomenon of frosting, and then the heat exchange property of micro-channel heat exchanger can be affected.
Therefore, how to solve the problems, such as that the condensed water on porous flat pipe surface in prior art is difficult discharge, easy frosting, become
Those skilled in the art's important technological problems to be solved.
Content of the invention
In view of this, it is an object of the invention to provide a kind of heat exchanger, the condensed water that its surface is formed is easily drained, and keeps away
Exempt from the problem of surface frosting.The present invention also aims to providing a kind of air-conditioning equipment including above-mentioned heat exchanger.
A kind of heat exchanger that the present invention provides, including inside be provided with the flat heat exchange pipe of refrigerant channel, described flat heat exchange pipe
Upper surface is inclined plane so that condensed water flows down along described inclined plane under gravity.
Preferably, described inclined plane is the inclined plane that middle part is high, edge is low.
Preferably, the cross section of described inclined plane be inverted " v ", and the bearing of trend at highest position of described inclined plane with
Described refrigerant channel is parallel.
Preferably, described flat heat exchange pipe is multiple and is vertically equally spaced.
Preferably, the surface of described flat heat exchange pipe is provided with heat exchange fin.
Preferably, described heat exchange fin is provided with for the gap under condensation flow.
Present invention also offers a kind of air-conditioning equipment, it is provided with heat exchanger, described heat exchanger is as above changing described in any one
