Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] See Figure 1-5The present invention provides a liquid cooling heat dissipation device 100, which includes a housing assembly, a liquid cooling plate 20 disposed within the housing assembly, and a heat-conducting component disposed on the liquid cooling plate 20. The liquid cooling plate 20 is provided with an inlet 21 and an outlet 22. The housing assembly includes a side plate 10, a panel assembly, and a cover plate 13. The side plate 10 has a fixing structure for fixedly connecting with the panel assembly and the cover plate 13. The heat-conducting component includes an insulating component disposed on the liquid cooling plate 20 and a heat-conducting component that abuts against a first heating element 30. The liquid cooling plate 20 also has a support structure for supporting a second heating element 31. By using a fixed structure to install the liquid cooling plate 20 onto the side plate 10 and fixing the side plate 10 to the panel assembly and the cover plate 13, the overall stability of the housing assembly can be effectively ensured. Furthermore, since the cross-section of the side plate 10 remains consistent along its length, the processing requirements of products with different depths can be met by cutting the side plate 10 and changing the length of the bent edges on both sides of the cover plate 13. This allows for the sizing of parts required for products with different power ratings, improving the versatility of parts within the housing assembly, increasing production efficiency, and saving production and manufacturing costs. Simultaneously, the use of heat-conducting components effectively improves the heat dissipation efficiency of the first heating element 30, which generates higher heat, through the liquid cooling plate 20, and insulating components ensure the safety of the first heating element 30 mounted on the liquid cooling plate 20. In addition, by using a support structure to mount the second heating element 31, which generates lower heat, onto the liquid cooling plate 20, the heat dissipation requirements of different heat-generating devices can be met, improving the heat dissipation effect and applicability of the liquid cooling device 100.

[0018] like Figure 2 As shown, the panel assembly includes a front panel 11 and a rear panel 12. The fixing structure includes several liquid cooling holes 101 located in the middle of the side panel 10 for fixed connection with the liquid cooling plate 20, first panel holes 102 located at both ends of the side panel 10 for fixed connection with the front panel 11 and the rear panel 12, and several first cover plate holes 103 located at the top and bottom of the side panel 10 for fixed connection with the cover plate 13. The liquid cooling plate 20 is fixedly connected to the side panel 10 by using bolts, studs and pins and other locking elements passing through the liquid cooling holes 101 on the side panel 10 and locking them in the liquid cooling plate 20. Furthermore, since the liquid cooling hole 101, the first panel hole 102, and the first cover plate hole 103 are all processed in subsequent processes, for UPS (uninterruptible power supply) products of different depths and sizes, the side plate 10 can be generated first using a mold, then the side plate 10 can be cut according to different product requirements, and finally the hole positions of the liquid cooling hole 101, the first panel hole 102, and the first cover plate hole 103 can be processed, thereby greatly improving production efficiency and saving production and manufacturing costs.

[0019] like Figure 2As shown, a plurality of liquid cooling holes 101 are evenly distributed on the side plate 10, first panel holes 102 are symmetrically distributed at both ends of the side plate 10, and a plurality of first cover plate holes 103 are symmetrically distributed at the top and bottom of the side plate 10 relative to the liquid cooling holes 101. By evenly distributing the plurality of liquid cooling holes 101 on the side plate 10, symmetrically distributing the first panel holes 102 at both ends of the side plate 10, and symmetrically distributing the plurality of first cover plate holes 103 at the top and bottom of the side plate 10 relative to the liquid cooling holes 101, the positioning accuracy and uniformity of the liquid cooling holes 101, the first panel holes 102 and the first cover plate holes 103 on the side plate 10 can be effectively improved, thereby ensuring the stability of the fixed connection between the side plate 10 and the front and rear panels 12, the cover plate 13 and the liquid cooling plate 20 through the liquid cooling holes 101, the first panel holes 102 and the first cover plate holes 103.

[0020] like Figure 2 As shown, the front panel 11 has a first side plate hole 111 for fixed connection with the first panel hole 102, a frame hole 112 for fixing the housing assembly into the frame, a light guide hole 113 for mounting light guide elements, and a handle 114. By using bolts, studs, and pins to pass through the first side plate hole 111 of the front panel 11 and lock them into the first panel hole 102 of the side plate 10, the side plate 10 can be fixedly connected to the front panel 11. By using locking members to pass through the frame hole 112 and lock them into the frame, the liquid cooling heat dissipation device 100 can be fixed into the frame using the front panel 11. Light guide elements such as light guide pillars can be mounted on the front panel 11 using the light guide hole 113 to indicate the operating status of the liquid cooling heat dissipation device 100. Furthermore, the handle 114 on the front panel 11 effectively improves the ease of installing and removing the liquid cooling heat dissipation device 100 from the frame.

[0021] like Figure 2 As shown, the rear panel 12 has a second side plate hole 121 for fixed connection with the first panel hole 102, a second cover plate hole 122 for fixed connection with the cover plate 13, and a clearance hole 123 for avoiding the inlet 21 and outlet 22. The rear panel 12 can be mounted on the side plate 10 by using a locking member that passes through the second side plate hole 121 and locks it into the first panel hole 102. The clearance hole 123 on the rear panel 12 allows the inlet 21 and outlet 22 of the liquid cooling plate 20 to protrude from the rear panel 12, effectively improving the convenience for operators to connect the inlet 21 and outlet 22 to external equipment.

[0022] like Figure 2 and Figure 3As shown, the cover plate 13 has a first bent edge 131 and a second bent edge 132. The first bent edge 131 has a third side plate hole 1311 for fixed connection with the hole of the cover plate 13, and the second bent edge 132 has a second panel hole 1321 for fixed connection with the rear panel 12. The installation steps of the assembly are as follows: First, the first heating element 30 is installed on the liquid cooling plate 20 using a heat-conducting component, and the second heating element 31 is installed on the liquid cooling plate 20 using a support structure. Then, bolts, studs, and pins are used as locking components to pass through the liquid cooling hole 101 on the side plate 10 and lock into the liquid cooling plate 20, thus fixing the liquid cooling plate 20 to the side plate 10. Next, locking components are used to pass through the third side plate hole 1311 on the cover plate 13 and lock into the cover plate hole 13 of the side plate 10, thus fixing the top of the cover plate 13 to the side plate 10. The front panel 10 is fixedly connected to the bottom. Then, bolts, studs, and pins are used as locking devices to pass through the first side plate hole 111 of the front panel 11 and lock into the first panel hole 102 of the side panel 10, thus fixing the side panel 10 to the front panel 11. Finally, locking devices are used to pass through the second side plate hole 121 of the rear panel 12 and lock into the first panel hole 102 of the side panel 10, and locking devices are used to pass through the second cover plate hole 122 of the rear panel 12 and lock into the second panel hole 1321 of the cover plate 13, thereby completing the assembly operation of the component. Since the cross-section of the side panel 10 is consistent in the length direction, the processing requirements of products with different depth dimensions can be met by cutting the side panel 10 and changing the length of the first bending edge 131 and the second bending edge 132 of the cover plate 13. This allows for the satisfaction of the part dimensions required for products with different power ranges, improving the versatility of the parts in the housing assembly, increasing production efficiency, and saving production and manufacturing costs.

[0023] like Figure 4 As shown, the first heating element 30 is a power transistor with copper sheets on it. The heat-conducting component is a ceramic substrate 42 that is bonded to the copper sheets of the power transistor. Since the power transistor has the highest power consumption and generates the most heat, it is directly bonded to the liquid cooling plate 20 to shorten the heat transfer path and improve heat dissipation efficiency. Furthermore, by placing the power transistor on a circuit board and using surface mount packaging to bond it to the liquid cooling plate 20, the copper sheets of the power transistor are positioned on top of the package, thereby effectively reducing the heat transfer path and thermal resistance of the internal heat source. Moreover, by placing the ceramic substrate 42 on the liquid cooling plate 20, the copper sheets can be directly bonded to the ceramic substrate 42, shortening the heat transfer path from the copper sheets to the liquid cooling plate 20 and improving heat dissipation efficiency.

[0024] like Figure 4 and Figure 5As shown, the insulating components include a first insulating element 41 and a second insulating element 43 that are attached to the liquid cooling plate 20, with a ceramic substrate 42 disposed between the first insulating element 41 and the second insulating element 43. The installation steps of the heat-conducting assembly are as follows: First, place the liquid cooling plate 20 on the worktable, then fix the first insulating element 41 in the desired position, and then place the ceramic substrate 42; next, due to limitations in the assembly process, there is a slight gap between the ceramic substrate 42 and the first set of insulating elements, resulting in 100% electrical insulation between the circuit board and the liquid cooling plate 20. Subsequently, the second set of insulating elements is installed to cover the gap between the ceramic substrate 42 and the first insulating element 41. Finally, the power transistor is fixedly connected to the liquid cooling plate 20, and the copper strip of the power transistor is attached to the ceramic substrate 42.

[0025] like Figure 5 and Figure 6 As shown, the second heating element 31 comprises several circuit boards, and the supporting structure consists of several support columns 50 for supporting the circuit boards. The heat generated by the second heating element 31 is lower than that of the first heating element 30. Therefore, by using the support columns 50 to mount the second heating element 31 onto the liquid cooling plate 20, heating elements with different power consumptions can be separated, thereby further improving the heat dissipation effect of the liquid cooling heat dissipation device 100. Furthermore, in the embodiment provided by this utility model, a thermally conductive pad is also provided between the circuit board and the support column 50, thereby effectively improving the thermal conductivity effect of transferring heat from the circuit board to the liquid cooling plate 20 for heat dissipation.

[0026] 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.
