Abstract

The utility model discloses a special-shaped channel hole flat tube, which relates to a heat transfer element. The utility model aims at providing the special-shaped channel hole flat tube which has a good heat transfer effect. The technical proposal of the utility model is to provide the special-shaped channel hole flat tube which comprises the channel hole of a flat tube body, wherein, a fin is arranged in the rectangular channel hole, and one end of the fin is connected with the flat tube body. The outer surface of the special-shaped channel flat tube is coated with zinc coating. The special-shaped channel hole flat tube of the utility model is used for an air-conditioner.

Description

A kind of special-shaped port hole flat tube
Technical field:
The utility model relates to a kind of heat-exchanging element, and the spy is a kind of special-shaped port hole flat tube that is used for heat exchange.
Background technique:
Existing multichannel hole flat tube, port hole is square, and its heat transfer area is less, and the heat exchange effect is undesirable, and in addition, the corrosion resistance of aluminum alloy flat tube is relatively poor, and working life is shorter.
Summary of the invention:
The purpose of this utility model provides a kind of special-shaped port hole flat tube of good effect of heat exchange.Further purpose of the present utility model provides the good special-shaped port hole flat tube of a kind of corrosion resistance.The technical solution of the utility model is, a kind of special-shaped port hole flat tube comprises the port hole of flat tube body, and it is characterized in that: rectangular channel is provided with fin in the hole, and an end of fin is connected with the flat tube body.The outer surface of described special-shaped passage flat tube is provided with the zinc layer.It is big that the utility model has heat exchange area compared with the prior art, and heat exchange efficiency height and corrosion resistance are good, the advantage of long service life.
Description of drawings:
Accompanying drawing is the cross-sectional structure schematic representation of the utility model abnormity port hole flat tube.
Embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, in order to increase the heat exchange area of flat tube port hole, fin 3 is set in the rectangular channel hole, one end of fin 3 is connected with flat tube body 1, make it to become special-shaped port hole 2, the heat exchange area of the flat tube of this special-shaped port hole is big, thereby good effect of heat exchange.In order to improve the corrosion resistance of aluminum flat tube, be provided with the zinc layer on the outer surface of flat tube, the zinc layer can plate, also the heat that can utilize flat tube to produce when extrusion moulding, when the extruding flat tube, zinc powder is sprayed on its surface, it is solidificated in forms the zinc layer on the flat tube body.
