Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation pipes, in particular to a heat dissipation pipe without ribs at the end. Background Art

[0002] The heat pipe is a necessary component of the radiator. In order to improve the pressure-bearing strength, convex ribs are generally provided on the heat pipe. For example, the utility model patent with announcement number CN202993940U discloses a single hourglass double-tube heat pipe, which increases the structural strength and pressure-bearing strength through two recessed bands. The convex ribs on the traditional heat pipe are opened to the end, and after matching with the main plate, sand holes are prone to occur, causing leakage. Utility Model Content

[0003] The utility model aims at the deficiencies of the prior art and provides a radiating pipe with no ribs at the end.

[0004] The utility model is realized by the following technical scheme, providing a heat dissipation tube without ribs at the end, comprising two tube walls arranged opposite to each other, wherein the tube walls are provided with convex ribs protruding toward the inner side of the heat dissipation tube, the convex ribs are long strips and parallel to the length direction of the heat dissipation tube, and the distance between the end of the convex rib and the end of the heat dissipation tube is H, and H is 5-10mm.

[0005] In this solution, the heat dissipation pipe is provided with convex ribs starting from 5mm to 10mm inward from the end, and there are no convex ribs at the contact between the end and the main plate, which greatly avoids the occurrence of problems such as sand holes, and the absence of convex ribs also facilitates assembly.

[0006] As an optimization, a convex portion is provided on the tube wall, and a plurality of convex groups arranged along the length direction of the heat dissipation tube are provided on the convex portion, and the convex group includes a plurality of convexities arranged along the width direction of the heat dissipation tube. The plurality of convexities provided in this solution play a role in strengthening the heat dissipation tube, and at the same time can play a role in disturbing the internal liquid, thereby improving the heat dissipation effect.

[0007] As an optimization, the distance between the end of the convex part and the end of the heat dissipation pipe is 5-10 mm. In this solution, the convex part also avoids the contact point between the end of the heat dissipation pipe and the main plate.

[0008] As an optimization, two convex ribs and three convex parts are provided on the tube wall, and the two convex ribs and the three convex parts are arranged alternately along the width direction of the heat dissipation tube. In this solution, the three convex parts strengthen and disturb the flow space on both sides of the convex ribs.

[0009] As an optimization, the embossment is in the shape of a long strip, and the embossment group includes two embossments and the two embossments are arranged in a figure eight shape. In this solution, the two embossments are arranged in a figure eight shape, thereby improving the reinforcement effect and the spoiler effect.

[0010] As an optimization, the length of the convex is 1.5-2.5 times of the width. In this solution, the convex length is set within a suitable range, and the spoiler effect is good.

[0011] As an optimization, the convexity is convex toward the inner side of the heat dissipation pipe. The convexity convex inwardly is inserted into the fluid, and the turbulence effect is good.

[0012] As an optimization, the distance between the two tube walls gradually decreases from the middle to the two ends along the width direction of the heat dissipation tube. In this solution, the distance between the tube walls is small at the ends and large in the middle, which increases the fluid flow and improves the strength of the heat dissipation tube.

[0013] The beneficial effects of the utility model are as follows: the utility model is a heat dissipation tube without ribs at the end, and the heat dissipation tube is provided with convex ribs starting from 5mm to 10mm inward from the end, and there are no convex ribs at the contact between the end and the main plate, which greatly avoids the occurrence of sand holes and other problems, and the absence of convex ribs also facilitates assembly, and the assembly efficiency is improved.
