The aluminum heat exchange tube is good in heat exchange effects, relatively low in cost, high in corrosion resistance and long in service life.
Description
Technical field
The utility model relates to a kind of aluminium tube, is specifically related to a kind of aluminium heat exchanger tube.
Background technology
Heat exchanger tube is one of element of heat exchanger, for the exchange of heat between two media.Heat exchanger is a kind of significant element equipment that is widely used in the fields such as oil refining, chemical industry, environmental protection, the energy, electric power, household electrical appliances.Existing heat exchanger tube material is selected the metals such as stainless steel, copper conventionally, and cost of material is higher, and on the other hand, existing heat exchanger tube area of dissipation is little, causes heat transfer efficiency lower, and its decay resistance is not good yet.
Utility model content
The utility model product is for the deficiencies in the prior art, provides a kind of good effect of heat exchange, cost is lower and good corrosion resistance, long aluminium heat exchanger tube of life-span.
In order to solve the problems of the technologies described above, the utility model product is achieved through the following technical solutions:
A kind of aluminium heat exchanger tube, comprise aluminum pipe body, it is characterized in that, the outer surface of aluminum pipe body is provided with first anode alumina layer, the inwall of described aluminum pipe body is uniformly distributed the elongated slot of a plurality of spaces, and the trend of each elongated slot is parallel with the central axis of body.So not only increase heat exchange area, and due to the protection of anodic aluminum oxide layer, make aluminium heat exchanger tube be difficult for being corroded.
Further, the cross section of described elongated slot is trapezoidal or triangle.
Preferably, the outer wall of described first anode oxidation film layer is also provided with a plurality of radiating wings.The external surface area that increases aluminum pipe body, further improves heat transfer effect, and " radiating wing " refers to and be located at the parts that play increase aluminum pipe body and external agency contact area on body outside.
Specifically, described radiating wing is annular.
Further, described radiating wing is comprised of aluminium matter radiating wing body and the third anode alumina layer being covered on described aluminium matter radiating wing body.Guarantee that radiating wing also has good corrosion resistance.
Preferably, the inner wall surface of described aluminum pipe body is also provided with second plate alumina layer.
Usually, described elongated slot has 10～40.
Further, the thickness of described first anode alumina layer is 5 μ m～15 μ m.
Aluminium heat exchanger tube of the present utility model, its beneficial effect is: the utility model is by arranging elongated slot (as Fig. 1) in aluminum pipe inner body wall, and be provided with one deck first anode alumina layer at outer surface, make aluminium heat exchanger tube of the present utility model have that heat exchange area is large, heat exchange efficiency is high, cost is low and have a good corrosion resistance, the advantage that the life-span is long.
