Embodiment Construction

[0015] refer to figure 1 As shown, the schematic diagram of the structure of Embodiment 1 of the present invention: a multi-channel aluminum flat tube 1 for heat dissipation includes a number of flow channels 2 formed by the tube wall and a number of partitions, and there are many protrusions or grooves on the outside of the tube wall 3. The contact area between the aluminum flat tube 1 and the external medium is increased, so its heat transfer efficiency is higher than that of the bare tube, and there is no need to braze the aluminum fins, and the corrosion resistance is also improved. At the same time, the protrusion or the groove 3 forms a rib plate, which acts as a reinforcing rib, improves the structural strength of the pipe body, and increases the mechanical stability.

Abstract

The invention relates to a multi-runner aluminum flat pipe for heat radiation, which comprises a plurality of runners which are formed by wall pipes and a plurality of clapboards, wherein a plurality of bulges or grooves are arranged at the outsides of the pipe walls, and the contact area between the aluminum flat pipe and an external medium is enlarged, so that the heat exchange efficiency of the aluminum flat pipe is higher than that of a light pipe, no aluminum fins are required to be brazed, and the corrosion resisting performance is improved. Simultaneously, the bulges or the grooves form rib plates, so that a function of reinforcing ribs can be played, the structural strength of a pipe body is enhanced, and the mechanical stability is enhanced. According to the multi-runner aluminum flat pipe for the heat radiation, the technical principle is simple, and the scheme is easy to realize, so that the application range of the multi-runner aluminum flat pipe is relatively wide.

Description

1. Technical field [0001] The invention belongs to the field of heat exchangers, in particular to a multi-channel aluminum flat tube for heat dissipation. 2. Background technology [0002] The external brazing aluminum fins of the multi-channel aluminum flat tube can be made into a parallel flow heat exchanger with good heat transfer effect. However, because the aluminum fins are very thin and have poor corrosion resistance, the current multi-channel parallel flow heat exchanger cannot be used in harsh environments, such as humid environments and acid-containing environments. 3. Contents of the invention [0003] (1) Purpose of the invention [0004] In view of the above-mentioned problems to be solved in the prior art, the purpose of the present invention is to propose a multi-channel aluminum flat tube for heat dissipation in harsh environments. The technical principle is simple and the scheme is easy to realize, so that the application range of the multi-channel alumin...
