Description

Technical Field

[0001] This utility model relates to the field of liquid cooling radiator technology, and more specifically, to a snap-on liquid cooling radiator. Background Technology

[0002] Liquid-cooled radiators utilize the high specific heat capacity of liquids to efficiently conduct and dissipate heat through the flowing liquid.

[0003] Power devices are semiconductor devices capable of handling high voltage and high current. They are widely used in electronic devices to convert and control electrical energy. Power devices mainly include diodes, thyristors, MOSFETs (metal-oxide-semiconductor field-effect transistors), and IGBTs (insulated-gate bipolar transistors). Generally, power devices are in a chip-like shape for easy installation in electronic devices.

[0004] Most existing liquid-cooled heat sinks feature a planar liquid cooling plate or a die-cast metal casing, with internal channels for liquid flow. Two liquid cooling plates or two die-cast metal casings are welded together in a relatively opposite position. The power device requiring heat dissipation is pressed tightly between the two cooling plates or the two die-cast metal casings by an insulating thermally conductive material. The heat generated by the power device is sequentially transferred through the insulating thermally conductive material, the liquid cooling plate or die-cast metal casing, the internal liquid channels, and the flowing liquid, and finally, the heat is dissipated from the power device by the flowing liquid. However, liquid-cooled heat sinks with planar liquid cooling plates or die-cast metal casings are often fixedly mounted on the power device and are a one-piece structure. When a part of the structure needs to be repaired or replaced, disassembly and reassembly are inconvenient.

[0005] The above shortcomings need to be addressed. Utility Model Content

[0006] In order to overcome the shortcomings of existing technologies, this utility model provides a snap-on liquid cooling radiator, which ensures good heat dissipation while being easy to disassemble and assemble, and convenient for inspection and replacement of parts.

[0007] The present invention provides a snap-fit ​​liquid cooling radiator for heat dissipation of power devices, comprising a fixing clip, a water pipe for liquid flow, and a detachable snap-fit ​​body; the water pipe is partially housed within the snap-fit ​​body; the side surface of the snap-fit ​​body is for the power device to be attached for heat dissipation; the two ends of the fixing clip are elastically pressed against the power device to clamp the snap-fit ​​body and the power device.

[0008] Compared with the prior art, the snap-fit ​​liquid cooling radiator provided by this utility model has a detachable snap-fit ​​structure for easy disassembly and assembly. The water pipe is housed in the snap-fit ​​body to allow the cooling liquid to flow from inside the snap-fit ​​body. This allows the power device to be in contact with the side surface of the snap-fit ​​body for heat dissipation. The fixing clips are also provided to clamp the power device to the side surface of the snap-fit ​​body to ensure good heat dissipation. At the same time, the fixing clips also further clamp the snap-fit ​​body, so that the snap-fit ​​body and the water pipe are in close contact. Therefore, the snap-fit ​​liquid cooling radiator provided by this utility model not only ensures good heat dissipation, but also does not require complicated operating tools for disassembly and assembly, making it convenient for inspection and replacement of parts.

[0009] Specifically, the fastener comprises two sub-bodies, which can be joined together.

[0010] Specifically, the sub-body includes a positioning protrusion and a positioning recess. The positioning protrusion on one sub-body can mate with the positioning recess on another sub-body to fit together. This arrangement facilitates the positioning and fitting of the two sub-body pieces and limits their mutual positioning, thereby preventing relative movement between the two sub-body pieces and improving the reliability of use.

[0011] Specifically, the length of the protruding end face of the positioning protrusion is 0.2-0.3 times the width of the buckle body. This design ensures both mechanical strength and reliable docking.

[0012] Specifically, the sub-body also includes a receiving groove, which is disposed between the positioning protrusion and the positioning recess, and the receiving grooves on the two sub-body are joined together to form a cavity for partially accommodating the water pipe.

[0013] Specifically, a heat-conducting layer is also provided between the receiving tank and the water pipe.

[0014] Specifically, the fixing clip has clamping sections at both ends, the middle parts of the two clamping sections are close to each other and the ends of the two clamping sections are opposite to each other.

[0015] Specifically, buffer pads are also provided on the opposing surfaces of the two clamping sections. This arrangement can effectively prevent the clamping sections of the fixing clip from damaging the surface of the power device. Attached Figure Description

[0026] Please see Figures 1 to 4The present invention provides a snap-fit ​​liquid cooling radiator 100 for heat dissipation of a power device 200. It includes a fixing clip 1, a water pipe 2 for cooling liquid flow, and a detachable snap-fit ​​body 3. The water pipe 2 is partially housed within the snap-fit ​​body 3, and both ends of the water pipe 2 are provided with connectors 20. One connector 20 is used to connect to the cooling liquid, while the other connector 20 is connected to a container for holding the cooling liquid after heat exchange with the power device 200. The side surface of the snap-fit ​​body 3 is fitted with the power device 200 for heat dissipation. The fixing clip 1 is elastically pressed against the power device 200 at both ends to clamp the snap-fit ​​body 3 and the power device 200. Specifically, the snap-fit ​​body 3 includes two sub-bodies 31, which can be joined together to form the snap-fit ​​body 3. Specifically, one sub-bodies 31 and the other sub-bodies 31 are joined symmetrically, meaning that rotating one sub-bodies 31 180 degrees will bring it to the position of the other sub-bodies 31. In this embodiment, the two ends of the water pipe 2 are bent to facilitate the installation of the connector 20, and the water pipe 2 is a metal water pipe. The power device 200 is in the shape of a sheet, and there is one buckle body 3, with the power device 200 attached to both sides of the buckle body 3. There are multiple fixing clips 1 to clamp the buckle body 3 at multiple points.

[0027] Further, please refer to Figure 5 In some other embodiments of this application, the number of buckles 3 is multiple, and the water pipe 2 has multiple bends to accommodate situations where the power device 200 has a complex layout.

[0028] Further, please refer to Figures 2 to 4 The sub-body 31 includes a positioning protrusion 311, a positioning recess 312, and a receiving groove 313. The positioning protrusion 311 on one sub-body 31 can mate with the positioning recess 312 on another sub-body 31 to fit together. This arrangement facilitates the positioning and fitting of the two sub-body 31s and limits their mutual positioning, thereby preventing relative movement between the two sub-body 31s and improving the reliability of use. The receiving groove 313 is disposed between the positioning protrusion 311 and the positioning recess 312, and the receiving grooves 313 on the two sub-body 31s are joined together to form a cavity for partially accommodating the water pipe 2.

[0029] To ensure both mechanical strength and reliability of the docking of the two sub-body 31, the length of the end face of the positioning protrusion 311 is 0.2-0.3 times the width of the buckle body 3. In this embodiment, the length of the end face of the positioning protrusion 311 is L1, the width of the buckle body 3 is L2, and L1 = 0.25L2.

[0030] Further, please refer to Figure 4To further reduce the thermal resistance between the water pipe 2 and the coupling body 3 and improve heat dissipation, a heat-conducting layer 4 is also provided between the receiving groove 313 and the water pipe 2. Simultaneously, the heat-conducting layer 4 fills the gap between the receiving groove 313 and the water pipe 2, ensuring a tight contact. In this embodiment, since the coupling body 3 is formed by the mating of two separable sub-bodies 31, the heat-conducting layer 4 is also divided into two parts, each fixedly disposed on the surface of the receiving groove 313 of one sub-bodies 31. When the two sub-bodies 31 are mated and joined together, the heat-conducting layer 4 is also correspondingly assembled into a complete cylindrical shape.

[0031] Further, please refer to Figure 4 The fixing clip 1 has clamping sections 11 at both ends. The middle parts of the two clamping sections 11 are close to each other, and the ends of the two clamping sections 11 are opposite to each other, thus forming a bent structure to provide clamping force. In addition, since the ends of the two clamping sections 11 are opposite to each other, a warped structure is formed, so there is a large gap between the ends of the clamping sections 11 and the buckle body 3, which makes it easy to open the clamping sections 11 at both ends of the fixing clip 1 to remove the fixing clip 1.

[0032] Further, please refer to Figure 2 and Figure 4 A buffer pad 5 is also provided on the opposing surfaces of the two clamping sections 11. This arrangement can effectively prevent the clamping sections 11 of the fixing clip 1 from damaging the surface of the power device 200. In this embodiment, the buffer pad 5 is made of silicone material, so the presence of the buffer pad 5 can further enhance the friction between the clamping section 11 and the power device 200, thereby enhancing the reliability of clamping.

[0033] The following is a description of the working principle of the snap-fit ​​liquid cooler 100 of this utility model. When the snap-fit ​​liquid cooler 100 needs to be installed on the power device 200, before the snap-fit ​​body 3 is attached to the power device 200, the fixing clips 1 are removed first, and then the position of the snap-fit ​​body 3 is adjusted so that both sides of the snap-fit ​​body 3 are attached to the power device 200. Then, multiple fixing clips 1 are clamped on the surface of the power device 200. Then, one end of the water pipe 2 is connected to the cooling liquid and the other end is connected to the container holding the cooling liquid after heat exchange. At this time, the installation of the snap-fit ​​liquid cooler 100 is completed. When the snap-fit ​​liquid cooler 100 needs to be removed, the connection with the cooling liquid is first disconnected through the connectors 20 at both ends of the water pipe 2. Then, all the fixing clips 1 are removed. Then, the snap-fit ​​body 3 is split in half. Finally, the water pipe 2 is removed. The removal of the snap-fit ​​liquid cooler 100 is completed.

[0034] Compared with the prior art, the snap-fit ​​liquid cooling radiator 100 provided by this utility model has a detachable snap-fit ​​body 3 for easy disassembly and assembly. The water pipe 2 is partially housed inside the snap-fit ​​body 3 so that the cooling liquid can flow from inside the snap-fit ​​body 3. This allows the power device 200 to be attached to the side surface of the snap-fit ​​body 3 for heat dissipation. The fixing clip 1 is also provided to clamp the power device 200 to the side surface of the snap-fit ​​body 3 to ensure good heat dissipation. At the same time, the fixing clip 1 will further clamp the snap-fit ​​body 3, so that the snap-fit ​​body 3 and the water pipe 2 are in close contact. Therefore, the snap-fit ​​liquid cooling radiator 100 provided by this utility model not only ensures good heat dissipation, but also does not require complicated operating tools during disassembly and assembly, making it convenient for inspection and replacement of parts.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
