AI Technical Summary
The cogging design of existing copper tubes is difficult to take into account both the water flow when pursuing the heat dissipation effect and gravity resistance of the capillary structure, resulting in a contradiction between the flat heat dehumidification effect and gravity resistance.
Design a high and low cogging copper tube. By providing a plurality of main teeth and secondary teeth in the copper tube, the length of the main teeth extending inwardly is greater than the secondary teeth, forming a first tooth and a second tooth of different widths. The width of the cog is twice or more than that of the second cog to create a capillary structure with good gravity resistance and a large amount of water flow.
The good gravity resistance of the capillary structure and the large amount of water flow are achieved, which reduces the probability of tooth collapse during processing and improves the ease of forming the capillary structure.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of heat pipes, in particular to a high and low tooth groove copper pipe. Background Art
[0002] The inner wall of the existing copper tube is provided with tooth grooves, and the heat dissipation capacity of the copper powder is improved by filling the tooth grooves with copper powder and sintering them into a capillary structure. In the existing design, the tooth grooves with wide tooth grooves leak more copper powder, and the gap of the capillary structure generated after sintering is small, which is conducive to the capillary effect and improves the anti-gravity performance. The tooth grooves with small tooth grooves are easy to get stuck with copper powder, and the gap formed is large. The large gap has poor anti-gravity performance, but the water flow rate is large, which is good for the heat dissipation effect of the heat pipe flat. Therefore, there is a need for a high-low tooth groove copper tube with both small tooth grooves and large tooth grooves, so that the generated capillary structure can have both good anti-gravity performance and large water flow characteristics. Utility Model Content
[0003] The main purpose of the utility model is to provide a high-low tooth groove copper tube which has both small tooth grooves and large tooth grooves and enables the generated capillary structure to have both good anti-gravity performance and a large water flow rate.
[0004] The utility model provides a high-low tooth groove copper tube, comprising a copper tube body, wherein a plurality of main teeth are evenly arranged in the copper tube body, and an auxiliary tooth is further arranged between the main teeth, wherein the main teeth extend to the inner side of the copper tube body by a length greater than that of the auxiliary teeth;
[0005] The auxiliary teeth divide the main teeth into two first tooth grooves and second tooth grooves of different widths. The first tooth grooves and the second tooth grooves of different sizes can make the generated capillary structure have both good anti-gravity performance and a large water flow rate.
[0006] Preferably, the width of the first tooth groove is twice or more than the width of the second tooth groove.
[0007] The beneficial effects of the high and low tooth groove copper tube of the utility model are:
[0008] 1. By setting the main teeth longer than the auxiliary teeth, the second tooth groove can be formed more easily and the probability of tooth breakage during processing can be reduced.
[0009] 2. By providing a wider first tooth groove and a narrower second tooth groove, the generated capillary structure can have both good anti-gravity performance and a larger water flow rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0014] Reference Figure 1 , an embodiment of the high and low tooth groove copper tube of the utility model is proposed:
[0015] A high-low tooth-groove copper tube comprises a copper tube body 1, in which a plurality of main teeth 2 are evenly arranged, and between which a secondary tooth 3 is arranged, and the main tooth 2 extends to the inner side of the copper tube body 1 by a length greater than that of the secondary tooth 3.
[0016] The auxiliary teeth 3 divide the main teeth 2 into two first tooth grooves 4 and second tooth grooves 5 of different widths, wherein the width of the first tooth groove 4 is twice or more than the width of the second tooth groove 5. In the present embodiment, the width of the first tooth groove 4 is exactly twice the width of the second tooth groove 5.
[0017] By providing a longer main tooth 2 than the auxiliary tooth 3, the second tooth groove 5 can be formed more easily and the probability of tooth breakage during processing can be reduced. By providing a wider first tooth groove 4 and a narrower second tooth groove 5, the generated capillary structure can have both good anti-gravity performance and a large water flow rate.
