Description

Technical Field

[0001] This utility model relates to the field of heat dissipation devices, and more specifically, to a liquid-cooled heat sink. Background Technology

[0002] Liquid-cooled radiators utilize the high specific heat capacity of liquids to efficiently conduct and dissipate heat through the flowing liquid. A typical liquid-cooled radiator includes a circulation pipe for the coolant and a radiator, with the radiator housed within the circulation pipe. To avoid obstructing components that do not require cooling and to ensure precise heat dissipation, the circulation pipe is usually arranged in a curved pattern. This design requires additional space for the curved sections of the circulation pipe, increasing the overall size of the device. Furthermore, the curved sections of the circulation pipe exhibit stress concentration, increasing the risk of leakage.

[0003] The above shortcomings need to be improved. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a liquid-cooled radiator that does not require additional circulation piping, has a more compact structure, and has a lower risk of leakage.

[0005] The liquid-cooled radiator provided by this utility model includes a first liquid-cooling component, a second liquid-cooling component, and a sealing assembly; the first liquid-cooling component has a first cavity for coolant to flow through, the second liquid-cooling component has a second cavity for coolant to flow through, one end of the first liquid-cooling component is connected to one end of the second liquid-cooling component, so that the first cavity and the second cavity are connected; the sealing assembly is disposed between the first cavity and the second cavity, so that the first cavity and the second cavity are connected in a sealed manner.

[0006] Compared with existing technologies, the liquid-cooled radiator provided by this invention features a first cavity for coolant flow within a first liquid-cooling component and a second cavity for coolant flow within a second liquid-cooling component. One end of the first liquid-cooling component is connected to one end of the second liquid-cooling component, thus connecting the first and second cavities. A sealing assembly is also provided between the first and second cavities, ensuring a sealed connection and forming a sealed circulation channel for coolant flow. Therefore, the first and second liquid-cooling components of this invention integrate the circulation pipes and heat sink into one unit, eliminating the need for additional circulation pipes, resulting in a more compact structure and smaller footprint. Furthermore, by connecting the first and second cavities, the liquid-cooled radiator reduces stress concentration areas, and the sealing assembly between the first and second cavities significantly reduces the risk of leakage.

[0007] Specifically, the first cavity is also provided with several axial straight grooves. This arrangement can increase the heat exchange area between the coolant and the first cavity to improve heat dissipation efficiency, while reducing the axial pressure drop and ensuring stable flow of the coolant.

[0008] Specifically, the first cavity has a positioning protrusion at one end facing the second liquid cooling component, and the second liquid cooling component has a positioning recess at one end facing the first liquid cooling component, which communicates with the second cavity. The positioning recess and the positioning protrusion can cooperate with each other to position and connect the first cavity and the second cavity. This design improves the docking accuracy between the first cavity of the first liquid cooling component and the second cavity of the second liquid cooling component, and also facilitates the positioning and docking of the first liquid cooling component and the second liquid cooling component.

[0009] Specifically, the sealing assembly includes a seal and a fastener. The seal is disposed between the positioning protrusion and the positioning recess to make the latter two fit together in a sealing manner. The fastener passes through the second liquid cooling component and is detachably fixedly connected to the first liquid cooling component.

[0010] Specifically, the seal is also provided with a through positioning hole for avoiding coolant.

[0011] According to one embodiment of this application, the sealing element is a sealing ring. This arrangement provides good waterproofing and shock absorption between the positioning protrusion and the positioning recess, ensuring reliable sealing.

[0012] According to another embodiment of this application, the sealant is a sealing adhesive layer.

[0013] According to another embodiment of this application, the seal is a metal sheet with indentations, and the seal is simultaneously embedded in the positioning recess and the positioning protrusion.

[0014] Specifically, one end of the second cavity is provided with a sealing plug and the other end is provided with a connector for connecting coolant, and the end of the first cavity away from the second cavity is also provided with the connector.

[0015] According to another embodiment of this application, there are two first liquid cooling components and one second liquid cooling component, and one end of the first cavity of each of the two first liquid cooling components is respectively sealed to both ends of the second cavity of the second liquid cooling component.

Detailed Implementation

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution.

"Many" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified. Example

[0026] Please see Figures 1 to 3 The liquid-cooled radiator 100 provided by this utility model includes a first liquid-cooling component 1, a second liquid-cooling component 2, and a sealing assembly 3. The first liquid-cooling component 1 has a first cavity 11 for coolant flow. The second liquid-cooling component 2 has a second cavity 21 for coolant flow. One end of the first liquid-cooling component 1 is connected to one end of the second liquid-cooling component 2, so that the first cavity 11 and the second cavity 21 are connected. The sealing assembly 3 is disposed between the first cavity 21 and the second cavity 21, so that the first cavity 11 and the second cavity 21 are connected in a sealed manner. Specifically, one end of the second cavity 21 has a sealing plug 22, and the other end has a connector 23 for connecting coolant. The end of the first cavity 11 away from the second cavity 21 also has a connector 23, thus forming a circulation path. One of the two connectors 23 is used for inputting coolant, and the other is used for discharging coolant after heat exchange. In this embodiment, there is one first liquid-cooling component 1 and one second liquid-cooling component 2, so the overall shape is roughly "L".

[0027] Further, please refer to Figure 3 and Figure 4 To increase the heat exchange area between the coolant and the first cavity 11 and improve heat dissipation efficiency, the first cavity 11 is also provided with several axial straight grooves 111. This arrangement can also reduce the axial pressure drop at the same time, ensuring stable flow of the coolant.

[0028] Further, please refer to Figures 2 to 4 The first cavity 11 has a positioning protrusion 12 at one end facing the second liquid cooling component 2, and the second liquid cooling component 2 has a positioning recess 24 communicating with the second cavity 21 at one end facing the first liquid cooling component 1. The positioning recess 24 and the positioning protrusion 12 can cooperate with each other to position and connect the first cavity 11 and the second cavity 21. This arrangement improves the docking accuracy between the first cavity 11 of the first liquid cooling component 1 and the second cavity 21 of the second liquid cooling component 2, and also facilitates the positioning and docking of the first liquid cooling component 1 and the second liquid cooling component 2.

[0029] Further, please refer to Figure 2 and Figure 3 The sealing assembly 3 includes a seal 31 and a fastener 32. The seal 31 is disposed between the positioning protrusion 12 and the positioning recess 24 to achieve a sealing fit between the latter two. The fastener 32 penetrates the second liquid cooler 2 and is detachably fixedly connected to the first liquid cooler 1. Specifically, the seal 31 has a through positioning hole 311 and a clearance hole 312 for avoiding coolant. In this embodiment, the seal 31 is a silicone sealing ring, and the fastener 32 is a fastening screw. When the first liquid cooler 1 and the second liquid cooler 2 are in sealed communication, the fastener 32 penetrates the second liquid cooler 2 and the positioning hole 311 and extends into the first liquid cooler 1, thereby fixing the first liquid cooler 1 and the second liquid cooler 2 relatively, and the two ends of the seal 31 are simultaneously squeezed by the first liquid cooler 1 and the second liquid cooler 2, thereby filling the gap at the connection between the first liquid cooler 1 and the second liquid cooler 2 to seal it. At the same time, this design also provides good waterproof and shock-absorbing performance between the positioning protrusion 12 and the positioning recess 24, further ensuring the reliability of the seal. Example

[0030] The difference between this embodiment and Embodiment 1 is that the sealing element 31 is a sealing adhesive layer. Simply put, in this case, the sealing element 31 is a sealing adhesive layer formed by sealing glue, and the first liquid cooling element 1 and the second liquid cooling element 2 are respectively bonded to the sealing element 31 to seal. Example

[0031] The difference between this embodiment and Embodiment 1 is that the sealing element 31 is a metal sheet with indentations, and the sealing element 31 is simultaneously embedded in the positioning recess 24 and the positioning protrusion 12. It should be noted that, in this case, the sealing element 31 needs to undergo plastic deformation under external pressure to embed itself into the first liquid cooling element 1 and the second liquid cooling element 2, thereby forming a mechanical seal. During this process, the surface of the metal sheet will develop indentations due to external pressure; the sealing principle is well known to those skilled in the art and will not be elaborated upon here. Example

[0032] Please see Figure 5 The difference between this embodiment and embodiment one is that there are two first liquid cooling components 1 and one second liquid cooling component 2. One end of the first cavity 11 of the two first liquid cooling components 1 is respectively sealed and connected to both ends of the second cavity 21 of the second liquid cooling component 2. At this time, the liquid cooling radiator 100 is roughly U-shaped.

[0033] The following is a description of the working principle of the liquid-cooled radiator 100 provided by this utility model. First, the first liquid-cooling component 1 and the second liquid-cooling component 2 are installed at the positions of the components that need heat dissipation, so that the surfaces of the first liquid-cooling component 1 and the second liquid-cooling component 2 are in close contact with the components that need heat dissipation. Next, the sealing plug 22 is used to seal one end of the second cavity 21 of the second liquid-cooling component 2. Then, coolant is introduced through one connector 23 and discharged through another connector 23 after heat exchange. At this point, the liquid-cooled radiator 100 is installed. When it is necessary to remove the liquid-cooled radiator 100, the transmission between the connector 23 and the coolant is first cut off, then the liquid-cooled radiator 100 is removed from the components that need heat dissipation, then the fasteners 32 are removed, and the first liquid-cooling component 1 and the second liquid-cooling component 2 are separated. At this point, the liquid-cooled radiator 100 is removed.

[0034] Compared with the prior art, the liquid-cooled radiator 100 provided by this utility model has a first cavity 11 for coolant flow inside the first liquid-cooling component 1, and a second cavity 21 for coolant flow inside the second liquid-cooling component 2. One end of the first liquid-cooling component 1 and one end of the second liquid-cooling component 2 are connected to each other, so that the first cavity 11 and the second cavity 21 are connected. At the same time, a sealing component 3 is provided between the first cavity 11 and the second cavity 21, so that the first cavity 11 and the second cavity 21 are connected in a sealed manner, thereby forming a sealed circulation channel for coolant flow. Therefore, the first liquid-cooling component 1 and the second liquid-cooling component 2 of the liquid-cooled radiator 100 provided by this utility model integrate the circulation pipeline and the heat sink into one unit, eliminating the need for additional circulation pipelines, resulting in a more compact structure and a smaller volume. In addition, since the liquid cooling radiator 100 provided by this utility model connects the first cavity 11 and the second cavity 21, thereby reducing the stress concentration area, and a sealing component 3 is provided between the first cavity 11 and the second cavity 21 to form a sealed circulation channel, the risk of leakage is greatly reduced.

[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.
