Description

Technical Field

[0001] This utility model belongs to the field of heat transfer element technology, specifically relating to a spiral heat dissipation tube. Background Technology

[0002] Heat dissipation tubes are a common type of heat transfer element, mainly composed of a tube shell, a wick, and end caps. The tube shell is mostly made of seamless metal steel tubes, with materials such as copper, aluminum, and carbon steel. They come in various shapes, including round and irregular shapes. The wick is made of capillary porous material and is tightly attached to the inner wall of the tube. The inside of the heat dissipation tube is evaporated. One end of the heat dissipation tube is the condensing end, and the other end is the evaporating end. When the evaporating end is heated, the liquid in the wick evaporates. The vapor flows to the condensing end under the pressure difference and condenses back into liquid. The liquid then flows back to the evaporating end on the wick. They are widely used in electronic equipment, heat dissipation modules, and other fields.

[0003] When the heat pipe undergoes a large temperature difference thermal cycle or is subjected to vibration and impact, the liquid wick may separate from the heat pipe wall, that is, the liquid wick detaches, which disrupts the liquid return flow. The heat pipe does not have a design to prevent the liquid wick from detaching, which is a defect and needs to be improved. Existing heat pipes have the problem of not having a design to prevent the liquid wick from detaching inside. To address this, this application proposes a spiral heat pipe. Utility Model Content

The inside of the heat dissipation pipe element 1 is drawn into a negative pressure state. One end of the heat dissipation pipe element 1 is a condensation end and the other end is an evaporation end.

[0019] In this embodiment, a fixing ring 4 is fixedly connected to the outer side of both ends of the heat dissipation pipe element 1. The side length of the contact cover 3 is distance H. The outer diameter of the fixing ring 4 is 2 mm smaller than the side length distance H of the contact cover 3. The fixing ring 4 serves to prevent the movement of the coiled copper wire 2.

[0022] Working principle and usage process of this utility model: When the heat pipe is in use, the heat pipe element 1 is drawn into a negative pressure state. One end of the heat pipe element 1 is the condensing end and the other end is the evaporating end. When the evaporating end is heated, the liquid in the first liquid suction core tube 11 evaporates. The vapor flows to the condensing end under the pressure difference and condenses into liquid. The liquid then flows back to the evaporating end on the liquid suction core.
