Problems solved by technology

However, this kind of flat tube has a complex structure, wide brazing points, high quality and stability requirements, relatively high thermal performance of the product compared with other structures, difficult cost control, and narrow product applications.
[0010] Although in recent years, some flat tubes formed by extrusion technology have appeared, but the wall thickness of these flat tubes can only be 0.45mm.

Embodiment 1

[0087] Referring to FIG. 1 , an aluminum extruded thin-walled profile 1 is composed of a flat channel tube 11 with equal thickness on the outer periphery of the tube body. The channel tube 11 has a flow channel 13 for cold and hot preparations. The wall thickness C of the pipe body wall is less than 0.45mm, and can even be less than 0.15mm. The cross-sectional shape of the hot and cold preparation channel 13 is approximately elliptical.

Embodiment 2

[0089] Referring to Fig. 2, an aluminum extruded thin-walled profile 1 is composed of two channel tubes 11 with equal thickness and flat shape on the outer periphery of the tube body wall. The two channel tubes 11 are parallel and independent to each other, and the channel tubes 11 pass through The connecting portion 12 is connected transversely to form a dual-channel parallel flow pipe. The connection part 12 is generally a flat strip structure, and its thickness is about twice the thickness of the tube wall of the channel tube 11 . If the thickness is less than 0.9mm, it can even reach 0.3mm. The length of the connecting part 12 is shorter than that of the fluid pipe 11, so as to facilitate the installation and positioning of the high-performance cooling and heat exchange products on the header. There is a symmetrical structure between the two channel pipes 1 .

[0090] There is a hot and cold preparation channel 13 inside the channel tube 11 . The two-channel pipe 11 is ...

Embodiment 3

[0092] Referring to FIG. 3 , an aluminum extruded thin-walled profile 1 is composed of three or more channel tubes 11 of equal thickness and flat shape on the outer periphery of the tube body wall. The three channel tubes 11 are parallel to each other and independent, and the channel tubes 11 They are horizontally connected by connecting parts 12 to form a parallel flow tube with three or more channels. The connection part 12 is generally a flat strip structure, and its thickness is about twice the thickness of the tube wall of the channel tube 11 . If the thickness is less than 0.9mm, it can even reach 0.3mm. The length of the connecting part 12 is shorter than that of the fluid pipe 11, so as to facilitate the installation and positioning of the high-performance cooling and heat exchange products on the header. The three channel pipes 11 are symmetrical structures.

[0093] The channel pipes 11 may be of a symmetrical structure or an asymmetrical structure. For example, t...

Abstract

An aluminum extrusion thin wall section bar is made of more than one flat though channels. The parallel through channels are independently connected through joint section horizontally, forming symmetrical or asymmetric multi through channels formed parallel flow channel. There are at least one coolant and heating agent flow channels with the cross section in any shape inside the through channel. At least part of the flow channels having the shape of round, elliptical, polygonal, wave or random combination of them to suit for varied requirements for coolants or heating agents. The parallel flow channels for coolants or heating agents form the dual flow channel aluminum extrusion thin wall section bar or multi channel aluminum extrusion thin wall section bar. Fins are used to separate the flow channels for coolants or heating agents. It can replace traditional electrolytic copper pipe, reduce energy consumption, environment pollution and improved utilization of resources. It has low recovery cost, with extensive applications.

Description

technical field [0001] The invention relates to an aluminum profile, especially an aluminum extruded thin-walled profile for assembling a cold and heat exchanger. The profile can be cut and assembled into a cold and heat exchanger according to requirements, and the assembly is convenient, Excellent radiation performance enables it to achieve the purpose of improving heat transfer efficiency. Background technique [0002] At present, the hot and cold agent channels of the cold and heat exchanger mostly use circular electrolytic copper tubes (specific gravity 8.9), but the cost of using electrolytic copper tubes is relatively high, and the weight of the heat exchanger is also heavy, and a large number of them are used Copper caused the scarcity of copper resources. In addition, in the manufacturing process of the electrolytic copper tube, more energy needs to be consumed, and the pollution to the environment is also serious, so that the resources cannot be effectively used. ...
