Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat conduction components, in particular to a heat conduction pipe. Background Art
[0002] In recent years, electronic devices have been gradually designed to be thinner and lighter, so the design of the heat dissipation device or structure in the electronic device must also be designed to be thinner and lighter. However, there are many ways to design heat pipes. The more commonly used type is that after the working fluid in the heat pipe is heated and turned into steam, the gaseous working fluid conducts the heat to the low-temperature heat dissipation area due to the natural phenomenon of heat, and then condenses into a liquid working fluid. A capillary layer is set inside to conduct the condensed liquid working fluid to the heated area, thus achieving a continuous cycle. However, as the heat transfer time goes by, the temperature difference between the evaporation section and the cooling section gradually approaches, which leads to a gradual decrease in the heat transfer effect, making it impossible to transfer heat stably. For this reason, we propose a heat pipe. Utility Model Content
[0003] The utility model provides a heat conducting pipe, which solves the problems raised by the above background technology.
[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: a heat-conducting pipe, including a heat-conducting pipe body, the heat-conducting pipe body including a heat-dissipating section, an evaporating section and a cooling section, the heat-conducting pipe body is annular, wherein a hollow cavity is opened through the middle of the heat-conducting pipe body, and a surrounding heat-transfer cavity is opened in the middle of the heat-conducting pipe body, and an adjusting cavity is opened inside the heat-conducting pipe body, and the inner walls of the heat-dissipating section of the heat-transfer cavity and the adjusting cavity are both provided with capillary wicks, and the wicks are filled with cooling liquid, and the heat-transfer cavity and the adjusting cavity are both vacuum, and the connecting inner wall between the heat-transfer cavity and the adjusting cavity is S-shaped.
[0005] Optionally, the evaporation section and the cooling section of the heat transfer chamber and the regulating chamber are arranged in reverse, and the material used for the entire heat conduction pipe body is a thermally conductive material.
[0006] Optionally, capillary wicks are disposed on inner walls on both sides of the heat transfer cavity, and the capillary wicks are respectively a first wick and a second wick.
[0007] Optionally, a capillary wick is disposed on the inner wall of the regulating cavity, and the capillary wick is a third wick.
[0008] Optionally, the capillary wick may be a lead-free wicking wire or a graphite rope.
[0009] The utility model has the following beneficial effects:
[0010] 1. The heat pipe has a double-layer design of a heat transfer cavity and a regulating cavity in the heat pipe body, and the coolant in the heat transfer cavity and the regulating cavity flows relatively, so that it can conduct heat stably and efficiently, thereby making its heat conduction performance better, and the annular design can increase the heating area of the heat pipe body, thereby making its heat conduction efficiency better.
[0011] 2. The heat pipe has a double-layer design of a heat transfer cavity and an adjusting cavity, so that the coolants in the heat transfer cavity and the adjusting cavity can transfer heat relatively, thereby forming a relatively large temperature difference between the evaporation section and the cooling section of the heat transfer cavity, thereby achieving a better heat transfer effect. When the coolant in the heat transfer cavity releases heat energy, the coolant in the adjusting cavity evaporates, and then quickly takes away the heat from the cooling section of the heat transfer cavity, thereby ensuring that a large temperature difference can be formed between them.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figures 1 to 4A heat-conducting pipe comprises a heat-conducting pipe body 1, wherein the heat-conducting pipe body 1 comprises a heat dissipation section, an evaporation section and a cooling section. The heat-conducting pipe body 1 is annular, wherein a hollow cavity 2 is provided through the middle of the heat-conducting pipe body 1, which can increase the heating area outside the heat-conducting pipe body 1, thereby making its heat transfer more efficient, and a surrounding heat transfer cavity 3 is provided in the middle of the heat-conducting pipe body 1, and a regulating cavity 4 is provided inside the heat-conducting pipe body 1. Through the double-layer design of the heat transfer cavity 3 and the regulating cavity 4, the coolants in the heat transfer cavity 3 and the regulating cavity 4 can transfer heat relatively, thereby making the evaporation section and the cooling section of the heat transfer cavity 3 form a relatively large temperature difference, thereby making its heat transfer effect Better yet, when the coolant in the heat transfer cavity 3 releases heat energy, the coolant in the regulating cavity 4 evaporates, and then quickly takes away the heat of the cooling section of the heat transfer cavity 3, thereby ensuring that a larger temperature difference can be formed therebetween. The inner walls of the heat transfer cavity 3 and the heat dissipation section of the regulating cavity 4 are both provided with capillary wicks, and the wicks are filled with coolant. Under the action of the capillary wicks, the coolant therein can reflux under the action of the capillary effect, thereby enabling it to circulate. At the same time, the heat transfer cavity 3 and the regulating cavity 4 are both vacuum, and the connecting inner wall between the heat transfer cavity 3 and the regulating cavity 4 is S-shaped, thereby making the heat transfer between the heat transfer cavity 3 and the regulating cavity 4 faster.
[0019] See also Figures 1 to 4 The evaporation section and cooling section of the heat transfer chamber 3 and the regulating chamber 4 are arranged in reverse, and the heat conduction pipe body 1 is made of a thermally conductive material, such as brass, copper alloy, aluminum alloy, silver, etc., so that it can transfer heat smoothly.
[0020] See also Figures 1 to 4 Capillary wicks are arranged on the inner walls of both sides of the heat transfer cavity 3, and the capillary wicks are respectively the first wick 5 and the second wick 6. Under the action of the first wick 5 and the second wick 6, the coolant inside can be smoothly refluxed.
[0021] See also Figures 1 to 4 A capillary wick is arranged on the inner wall of the regulating cavity 4, and the capillary wick is the third wick 7, so that the coolant in the regulating cavity 4 can flow back smoothly.
[0022] See also Figures 1 to 4 , the coolant can be pure water or ethanol, etc.
[0023] See also Figures 1 to 4 The capillary wick can be a lead-free wick, a graphite rope, etc.
[0024] In summary, when the heat pipe is in use, after the evaporation section of the heat pipe body 1 is heated, the temperature of the evaporation section of the heat transfer cavity 3 rises, and the evaporation in the first liquid wick 5 and the second liquid wick 6 turns into gas, which absorbs a large amount of heat at this time. The steam will quickly take away the heat of the evaporation section, and then the steam flows to the cooling section to form liquid again. In the process of becoming liquid, the heat once absorbed will be released again. The coolant in the first liquid wick 5 and the second liquid wick 6 of the evaporation section has become dry after evaporation, while the liquid in the cooling section is constantly increasing. The liquid can flow back from the cooling section to the evaporation section under the action of capillary effect, and then complete a relatively closed cycle, so that the heat can be efficiently and stably conducted, and the heat is conducted in the regulating cavity 4, and the coolant in the heat transfer cavity 3 is relatively transferred along with the coolant in the heat transfer cavity 3. When the coolant in the regulating cavity 4 releases heat, the coolant in the heat transfer cavity 3 can absorb heat and take away part of the heat for reverse conduction, so that the heat pipe body 1 can conduct heat stably.
