Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a liquid-cooled heat pipe radiator. Background Technology

[0002] Liquid-cooled heat pipe radiators, as a highly efficient heat dissipation device, have been widely used in electronic equipment, servers, high-power LEDs, and other fields. They achieve heat dissipation through the simultaneous cooperation of heat pipes and liquid cooling circulation systems. In current mainstream designs, the circulation of coolant often relies on forced convection by a fan to achieve cooling, that is, the fan drives airflow through the surface of the heat sink to accelerate the release of heat from the coolant.

[0003] However, existing technologies have significant shortcomings: during long-term fan operation, external dust will adhere to the surface of the heat sink with the airflow, forming a dense dust layer. This dust accumulation hinders the direct contact between the heat sink and the air, reducing heat exchange efficiency. Subsequently, in order to compensate for the decrease in heat dissipation efficiency, the liquid cooling system needs to increase the fan speed or extend the operating time, which in turn exacerbates dust adsorption and increases energy consumption.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 5 As shown, this application provides a liquid-cooled heat pipe radiator, including: a radiator body 100, including a liquid cooling plate 10, heat pipes 20, heat dissipation fins 30, a heat dissipation frame 80, and a fan 101. The heat pipes 20 are located at the bottom of the liquid cooling plate 10, and the heat dissipation fins 30 are located outside the heat pipes 20. A liquid delivery pipe 40 is connected to the middle of the liquid cooling plate 10, and inlet pipes 50 and outlet pipes 60 are respectively connected to both ends of the liquid delivery pipe 40. A pump body 70 is provided in the middle of the outlet pipe 60; cleaning assembly. Component 90 is located in the middle of the heat sink 80 and the fan 101. It includes a support frame 91 fixed to the upper end of the heat sink 80, and a drive motor 92 is provided on the outer side of the support frame 91. The output end of the drive motor 92 is connected to a threaded rod 93, and a bearing 94 is provided at the connection between the threaded rod 93 and the support frame 91. A movable frame 95 is provided in the middle of the support frame 91, and a threaded hole 97 is opened in the middle of the movable frame 95. A cleaning brush 96 and a limit switch 98 are provided on the outer side of the movable frame 95.

[0028] After adopting the above technical solution, since the cleaning component 90 is located in the middle of the heat sink 80 and the fan 101, when the dust on the outside of the heat sink 81 needs to be cleaned, the cleaning component 90 is controlled by the external controller to perform the dust cleaning operation on the heat sink 81. This can solve the problem that during the long-term operation of the fan, external dust will adhere to the surface of the heat sink with the airflow, forming a dense dust layer. This dust accumulation will hinder the direct contact between the heat sink and the air, reducing the heat exchange efficiency. Subsequently, in order to compensate for the decrease in heat dissipation efficiency, the liquid cooling system needs to increase the fan speed or extend the working time, which will aggravate the problem of dust adsorption and increase energy consumption.

[0029] It should be noted that when the heat sink 81 needs cleaning, the output end of the drive motor 92, controlled by an external controller, drives the threaded rod 93 to rotate along the bearing 94, causing the threaded rod 93 to rotate along the inside of the threaded hole 97, thus moving the moving frame 95. During the movement of the moving frame 95, the cleaning brush 96 is driven to clean the dust along the heat sink 81. At the same time, during the movement of the moving frame 95, the slider 99 slides along the inside of the slide groove 910 until the limit switch 98 contacts one side of the support frame 91, which feeds back to the control circuit board. The output end of the drive motor 92 is then controlled to drive the threaded rod 93 to rotate in the opposite direction, thus causing the threaded rod 93 to rotate in the opposite direction along the inside of the threaded hole 97, thus moving the moving frame 95 in the opposite direction until another set of limit switches 98 contacts the other end of the support frame 91, thereby cleaning the heat sink 81 back and forth. During the cleaning process, the fan 101 continuously blows air to remove the dust without affecting the heat dissipation operation of the heat sink 81.

[0030] In one optional embodiment, there are four groups of heat pipes 20 arranged in an array, and several groups of heat dissipation fins 30 arranged in an array. The several groups of heat dissipation fins 30 are in contact with the heat pipes 20, so that the liquid cooling plate 10 can be in contact with the component that needs to be cooled, absorb heat through the heat pipes 20, and then dissipate heat through the heat dissipation fins 30.

[0031] In one optional embodiment, the liquid delivery pipe 40 is connected to both the inlet pipe 50 and the outlet pipe 60. A heat dissipation pipe is provided in the middle of the heat dissipation frame 80, and the heat dissipation pipe is connected to both the inlet pipe 50 and the outlet pipe 60. Several sets of heat dissipation fins 81 are provided on the outside of the heat dissipation pipe. When the pump body 70 is started, the coolant flows from the liquid delivery pipe 40 into the interior of the outlet pipe 60, and then into the heat dissipation pipe inside the heat dissipation frame 80. The coolant is dissipated by the heat dissipation fins 81, and the heat is dissipated by the fan 101 blowing air onto the heat dissipation fins 81, thereby achieving the heat dissipation effect.

[0032] In an optional embodiment, the pump body 70 is electrically connected to an external controller, and both ends of the pump body 70 are connected to the outlet pipe 60 respectively. The pump body 70 can transport the coolant that has absorbed heat inside the liquid delivery pipe 40, cool it down, and then circulate it.

[0033] In one optional embodiment, the support frame 91 and the heat sink 80 are fixedly connected, and the support frame 91 is a rectangular frame structure. The drive motor 92 is connected to the support frame 91 by bolts, which can support and install the drive motor 92, providing a foundation for the subsequent rotation of the threaded rod 93.

[0034] In one optional embodiment, the output end of the drive motor 92 is fixedly connected to the threaded rod 93, the threaded rod 93 is movably connected to the bearing 94, and the threaded rod 93 is adapted to the threaded hole 97. The output end of the drive motor 92 drives the threaded rod 93 to rotate along the inside of the threaded hole 97, so that the movable frame 95 moves along the inside of the support frame 91.

[0035] In one optional embodiment, the movable frame 95 has a rectangular structure, and the movable frame 95 is fixedly connected to the cleaning brush 96. The cleaning brush 96 is in contact with the heat sink 81, so that the movable frame 95 can drive the cleaning brush 96 to sweep along the upper end of the heat sink 81 and remove the attached dust.

[0036] In one optional embodiment, the limit switches 98 are in two sets and symmetrically distributed. They can be triggered when the moving frame 95 contacts both ends of the support frame 91, and the feedback is sent to the external controller. The drive motor 92 drives the switch to rotate in both directions. A slider 99 is fixedly connected to the outside of the moving frame 95. The slider 99 has a rectangular structure. The inner side of the support frame 91 has a groove 910 that matches the slider 99. The groove 910 is in two sets and symmetrically distributed. This allows the slider 99 to slide along the inner side of the groove 910 during the movement of the moving frame 95, ensuring the stability of the moving frame 95 during operation.
