Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a vertical heat pipe radiator. Background Art

[0002] At present, the heat dissipation of industrial products is carried out through radiators. As the power density continues to increase, traditional radiators can no longer meet the heat dissipation needs, and heat pipe radiators have been introduced.

[0003] Heat pipe radiator is an efficient heat dissipation technology that buries heat pipes in traditional radiators. Its working principle is based on heat conduction and phase change heat dissipation.

[0004] When the heat pipe radiator is used in the direction of gravity (i.e. vertical direction) (called vertical heat pipe radiator), the liquid filled inside the heat pipe will gather at the lower part of the heat pipe due to gravity; if it is subjected to high and low temperature shocks, the volume change caused by the phase change of the liquid in the heat pipe will bring an expansion force from the inside to the outside to the wall of the lower part of the heat pipe, which may cause the closed heat pipe to bulge due to the pressure, forming a tube expansion phenomenon, or even cracking, thereby causing the leakage of the liquid inside the heat pipe, which directly affects the thermal conductivity of the heat pipe, and in severe cases, the heat pipe radiator will be scrapped.

[0005] Therefore, there is a need to improve the existing technology.

[0006] The above information is presented as background information only to assist with an understanding of the present disclosure and is not a determination or admission that any of the above may be applicable as prior art with respect to the present disclosure. Utility Model Content

[0037] Example 1

[0038] In view of the aforementioned deficiencies in the prior art, the applicant, drawing upon years of extensive practical experience and expertise in the design and manufacture of similar products, combined with the application of academic theory, has actively engaged in research and innovation, hoping to create a technology that can address these deficiencies. Through continuous research and design, and through repeated trial production and refinement, the applicant has finally created the present utility model, which possesses truly practical value.

[0039] Please refer to Figure 1-2 The embodiment of the present invention provides a vertical heat pipe radiator, which is characterized by comprising a radiator body 1 and a plurality of heat pipes 2; wherein,

[0040] A plurality of heat pipes 2 are arranged at intervals inside the radiator body 1 and are arranged vertically;

[0041] The lower portion of each heat pipe 2 is arranged horizontally.

[0042] It should be noted that this embodiment adopts an innovative design, that is, the heat pipe 2, which was originally set vertically, is changed to a horizontal setting in its lower area. This ingenious design brings significant advantages: the liquid that naturally gathers under the action of gravity will mainly accumulate in the horizontal section at the bottom of the heat pipe 2. This provides more ample space buffer for the thermal expansion and contraction process of the liquid, thereby effectively avoiding adverse conditions such as excessive expansion of the heat pipe or even cracking, liquid leakage, etc. caused by changes in the liquid volume; in addition, it can also extend the heat dissipation area to a certain extent, promote the efficient dissipation of heat, and thus ensure that the vertical heat pipe radiator can continue to maintain its excellent heat dissipation performance in more stringent working environments. This innovative design not only helps to maintain the excellent thermal conductivity of the heat pipe radiator for a long time, but also significantly extends the service life of the heat pipe radiator, demonstrating a high degree of practical value and technological innovation.

[0043] Please refer again Figure 1-2 In one implementation of this embodiment, the vertical heat pipe radiator further includes a pressing block 3;

[0044] The pressing block 3 is fixedly arranged on the radiator body 1 at a position corresponding to the lower portion of the heat pipe 2 .

[0045] It should be noted that this design aims to provide stable restraint and support to the lower horizontal section of heat pipe 2 through the compression of pressure block 3, effectively offsetting the volume change caused by the phase change of the liquid inside heat pipe 2. This ensures the structural stability of heat pipe 2 while further improving the reliability of the overall structure of the vertical heat pipe radiator. The introduction of pressure block 3 helps prevent structural loosening or deformation caused by excessive expansion due to the phase change of the liquid inside heat pipe 2.

[0046] In one implementation of this embodiment, multiple options are provided for the fixed connection between the pressing block 3 and the radiator body 1 to ensure the stability and reliability of the structure. Specifically, the pressing block 3 can be firmly connected to the radiator body 1 by any of the following methods:

[0047] Threaded connection: This is a common and easy-to-use connection method. Threaded connection is not only easy to install and disassemble, but also allows for fine-tuning when necessary to suit different installation requirements.

[0048] Welding: Welding is a more permanent connection method. It melts the metal at the contact surface of the fin 3 and the heat sink body 1 at high temperature, allowing the two to form a single piece after cooling. Welding provides extremely high strength and sealing, making it suitable for applications requiring high structural strength and durability.

[0049] Bonding: A specific adhesive is used to tightly adhere the compression block 3 to the heat sink body 1, forming a strong bond through a chemical reaction or physical curing process. Adhesive bonding offers advantages such as ease of operation and adaptability, making it particularly suitable for applications that are sensitive to thermal stress or require avoiding direct metal contact.

[0050] In summary, the various fixing methods provided in this embodiment are intended to meet the specific needs of different application scenarios, ensuring a firm and reliable connection between the pressing block 3 and the radiator body 1, thereby further improving the overall performance and durability of the vertical heat pipe radiator.

[0051] Please refer again Figure 1-2 In one implementation of this embodiment, the pressing block 3 and the radiator body 1 are preferably fixedly connected by screws 4.

[0052] It should be noted that screw 4, serving as a connection medium, has one end screwed into a pre-threaded hole in the radiator body 1 and the other end passed through a pre-reserved through-hole in the clamp 3. By tightening, the clamp 3 is tightly attached to the radiator body 1 and effectively constrains and supports the lower horizontal section of the heat pipe 2. The tightening action of screw 4 not only ensures a secure connection between the clamp 3 and the radiator body 1, but also allows for a certain degree of adjustment in the degree of compression applied by the clamp 3 to the heat pipe, to accommodate different installation and heat dissipation requirements.

[0053] By adopting screws 4 as a fixed connection method, this embodiment not only achieves a simple, fast and reliable connection between the pressure block 3 and the radiator body 1, but also gives the structure a certain flexibility and adjustability, thereby further improving the overall performance and scope of application of the vertical heat pipe radiator.

[0054] In one implementation of this embodiment, the heat pipe 2 includes a sealing tube and a liquid wick;

[0055] The interior of the sealed tube is vacuum and filled with volatile liquid;

[0056] The wick, a key auxiliary structure, is attached to the inner wall of the heat pipe 2. The capillary action of the wick plays a vital role in the operation of the heat pipe: it is responsible for guiding the condensed liquid along the pipe wall back to the evaporation section, ensuring the continuity and efficiency of the liquid circulation inside the heat pipe.

[0057] In one implementation of this embodiment, the liquid is any one of distilled water, ammonia, methanol, and acetone. These substances are suitable for use in the working cycle of the heat pipe due to their unique physical properties.

[0058] It's important to note that when the evaporator section of a vertical heat pipe radiator comes into contact with a heat source (such as a power semiconductor device) and absorbs the heat generated, the liquid inside the sealed tube begins to boil and converts to steam. This heat-carrying vapor, driven by the pressure differential within the tube, moves from the evaporator section to the cooling section. In the cooling section, the vapor exchanges heat with the external environment or a cooling medium, releasing heat and condensing back into a liquid state. The condensed liquid is then efficiently transported back along the tube wall by the capillary force of the wick, preparing to begin a new evaporation-condensation cycle. This process repeats itself, continuously transferring heat from the heat source to the cooling section of the radiator, achieving efficient heat dissipation.

[0059] In summary, through the carefully designed sealing tube, liquid wick and selected working liquid, the heat pipe 2 in this embodiment exhibits excellent thermal conductivity and cycle stability, providing strong heat dissipation support for the vertical heat pipe radiator.

[0060] Although the terms "heat sink body," "heat pipe," and "press block" are frequently used in this application, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.

[0061] The embodiment of the present invention provides a vertical heat pipe radiator, which arranges the lower portion of the vertically arranged heat pipe horizontally so that the liquid gathered due to gravity is located in the lower horizontal section of the heat pipe, providing a larger space margin for the expansion and contraction of the liquid, avoiding the problem of tube expansion or even rupture and leakage of liquid, which is conducive to maintaining the thermal conductivity of the heat pipe radiator for a long time and extending the service life of the heat pipe radiator.

[0062] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
