Description
Technical Field
[0001] This utility model relates to the field of heat conduction and heat dissipation technology, specifically a heat pipe with a heat dissipation core. Background Technology
[0002] Heat dissipation is crucial in many fields, including electronic devices and industrial equipment. Heat pipes, as highly efficient heat transfer components, can rapidly transfer heat from the heat source to the heat dissipation area. However, existing heat pipes still have room for improvement in terms of heat dissipation efficiency.
[0003] Based on the above, the inventors have discovered the following problems: When using current heat pipes, their internal structure is relatively simple. When heat is transferred inside the pipe, the internal space cannot be fully utilized for efficient heat dissipation, resulting in the heat dissipation speed being unable to meet the increasing heat dissipation requirements of some high-performance devices.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a heat pipe with a heat dissipation core in order to achieve a more practical purpose. Utility Model Content

[0014] Furthermore, the surface of the heat sink core is provided with a plurality of flow guide holes, which are circular in shape.
[0015] The beneficial effect of adopting the above-mentioned further solution is that by opening several flow guide holes on the surface of the heat sink, the flow state of the coolant in the heat sink can be changed, the turbulence of the coolant can be promoted, the contact area and time between the coolant and the heat sink can be increased, thereby improving the heat exchange efficiency and better realizing heat transfer.
[0016] Furthermore, the tube body, heat dissipation fins, and heat dissipation core are all made of copper.

Simultaneously, the connecting pipes and connecting discs at both ends of the pipe facilitate connection with other components, enabling coolant circulation. The evenly spaced distribution of several heat dissipation fins ensures uniform airflow between the fins, facilitating effective heat dissipation. The wavy pattern of the heat dissipation fins further increases the heat dissipation area and improves heat dissipation performance. The integral molding of the heat dissipation fins and the pipe body ensures good thermal conductivity between them, reducing thermal resistance and allowing heat to be transferred more smoothly from the pipe body to the heat dissipation fins, thereby improving overall heat dissipation efficiency. Furthermore, the surface of the heat dissipation core has several conductive... The flow holes alter the flow state of the coolant within the heat sink core, promoting turbulence and increasing the contact area and time between the coolant and the heat sink core, thereby improving heat exchange efficiency and facilitating better heat transfer. The tube body, heat sink fins, and heat sink core are all made of copper, giving them excellent thermal conductivity and enabling rapid heat conduction, ensuring the overall high-efficiency heat dissipation of the heat pipe. A sealing gasket is embedded on one side of the connecting plate to effectively prevent coolant leakage at the connection points, ensuring the sealing and stability of the entire heat dissipation system.
