Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and in particular to heat pipe radiators. Background Technology

[0002] The miniaturization of electronic devices and the high integration of electronic components result in concentrated heat during operation, leading to localized temperature increases. High temperatures not only cause instability and pose safety risks during operation but also accelerate material aging and reduce lifespan. Therefore, for electronic components with concentrated heat, efficient heat dissipation devices such as heat pipe radiators are needed to quickly dissipate heat and reduce temperature rise.

[0003] A heat pipe cooler typically consists of a base, heat pipes, and a cooling module. The heat pipes contact both the base and the cooling module. During installation and use, the base absorbs heat from the heat source and conducts it to the heat pipes. The heat pipes then rapidly transfer the heat to the cooling module, where its large surface area dissipates the heat. A fan can also be installed on the cooling module to further enhance airflow and improve heat dissipation.

[0004] In the above scheme, the heat conduction path is heat source-base-heat pipe-heat dissipation module. The heat conduction path is relatively long and requires multiple contact heat exchange, so the heat conduction efficiency needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a heat pipe radiator that directly contacts the heat source, which can improve heat conduction efficiency and thus improve heat dissipation effect.

[0006] To achieve the above objectives, a heat pipe radiator with direct heat source contact is provided, comprising: a base plate having a first mounting groove extending vertically through the base plate; a first heat pipe having a heat absorption section, a conduction section, and a heat dissipation section arranged sequentially, the heat absorption section being disposed within the first mounting groove; a heat dissipation module fixedly disposed on the top of the base plate and abutting against the top of the heat absorption section, the heat dissipation section being inserted into the heat dissipation module; the conduction section comprising a straight section and arc-shaped transition sections located at both ends of the straight section, forming an installation space between the two transition sections, the heat dissipation module having an extension portion located within the installation space.

[0025] Reference Figures 1-3 This utility model discloses a heat pipe radiator with direct heat source contact, comprising a base plate 10, a first heat pipe component 20, and a heat dissipation module 30. The base plate 10 has a first mounting groove 11 extending vertically, and a first hole 12 and a second hole 13 are provided on the side of the first mounting groove 11 on the base plate 10. Fasteners installed in the first hole 12 are used to connect the base plate 10 and the heat dissipation module 30, and fasteners installed in the second hole 13 are used to connect the base plate 10 and the heat source. The first heat pipe component 20 has a heat absorption section 21, a conduction section 22, and a heat dissipation section 23 arranged sequentially, with the heat absorption section 21 disposed within the first mounting groove 11. The heat dissipation module 30 is fixedly disposed on the top of the base plate 10, with the bottom of the heat dissipation module 30 abutting against the top of the heat absorption section 21, and the heat dissipation section 23 inserted into the heat dissipation module 30. The conductive section 22 includes a straight section 221 and an arc-shaped transition section 222 located at both ends of the straight section 221. An installation space is formed between the two transition sections 222, and the heat dissipation module 30 has an extension 31 located in the installation space.

[0026] During installation and use, the heat-absorbing section 21 of the first heat pipe 20 can directly contact the heat source to absorb heat, and then quickly conduct the heat to the heat dissipation module 30, utilizing the surface of the heat dissipation module 30 for heat dissipation. The heat conduction path is heat source-heat pipe-heat dissipation module 30, which is a short path and reduces the number of contact heat exchange cycles, thus improving heat conduction efficiency and heat dissipation effect. Furthermore, the extension 31 increases the heat dissipation surface area of ​​the heat dissipation module 30 without increasing the overall width of the radiator, further improving heat dissipation efficiency.

[0027] In this embodiment, the distance between the extension 31 and the conductive section 22 is 0.05 to 0.25 mm. This structure avoids interference between the extension 31 and the first heat pipe 20 during assembly, and some of the heat from the heat pipe can be conducted to the extension 31 in a radiative manner, with the surface of the extension 31 dissipating the heat.

[0028] In this embodiment, the extension 31 includes a plate 311, the outer side of which is arc-shaped opposite to the transition section 222, and a first heat sink 34 parallel to the straight section 221 is provided on the plate 311. This structure can increase the heat dissipation surface area.

[0029] In this embodiment, both the heat absorption section 21 and the heat release section 23 have rectangular cross-sections. Specifically, the first heat pipe 20 adopts a design with square ends and a round middle, which reduces the production difficulty and cost of the first heat pipe 20; and this structure increases the contact area between the first heat pipe 20 and the heat source and heat dissipation module 30, thereby reducing thermal resistance and improving heat conduction efficiency through planar contact.

[0030] In this embodiment, multiple first heat pipe components 20 are configured, with the heat-absorbing sections 21 of the multiple first heat pipe components 20 arranged in sequence within the first mounting groove 11, and the heat-dissipating sections 23 of the multiple first heat pipe components 20 arranged at intervals. This structure can improve the heat absorption efficiency of the heat source and the heat dissipation efficiency of the heat dissipation module 30.

[0031] In this embodiment, the heat dissipation module 30 includes a first heat sink 32 and a second heat sink 33. Two first heat sinks 32 are arranged vertically opposite each other. Multiple first heat sink fins 34 are spaced apart on opposite sides of the two first heat sinks 32. The lower first heat sink 32 is fixedly connected to the base plate 10. The second heat sink 33 is fixedly mounted on the top of the upper first heat sink 32. Multiple first heat sink fins 34 are spaced apart on the second heat sink 33. A heat dissipation section 23 is inserted between the upper first heat sink 32 and the second heat sink 33. The thickness of the first heat sink fins 34 is no greater than 0.6 mm, and the gap width between adjacent first heat sink fins 34 is no greater than 3 mm. In this structure, the first heat sink fins 34 have a large total surface area and a low height, resulting in a short heat conduction distance and improved heat dissipation efficiency.

[0032] Fan mounting holes 35 are provided on one side of the second heat sink 33 and the front side of the base plate 10. This structure allows a fan to be installed on the heat dissipation module 30 to improve heat dissipation efficiency.

[0033] The bottom surface of the second heat sink 33 has a second mounting groove 331, and the heat dissipation section 23 is inserted into the second mounting groove 331. The heat dissipation section 23 absorbs heat through contact between the inner surface of the second mounting groove 331 and the heat dissipation section 23, thereby increasing the contact area and reducing thermal resistance.

[0034] Each of the two first heat sinks 32 has a support plate 36 on its opposite side, and the support plates 36 on the two first heat sinks 32 abut against each other. This structure improves the compressive strength and prevents the two first heat sinks 32 from deforming and shifting under longitudinal pressure, which would lead to deformation of the heat pipe and the first heat sink 34.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
