Abstract
Description
Technical Field
[0001] This application relates to the field of liquid cooling equipment technology, and in particular to a cooling box. Background Technology
[0002] Server chassis and other equipment typically generate heat during use due to high-load operations. To ensure the normal operation of the server chassis, it is placed in a cooling box, where flowing coolant carries away the heat from the chassis for cooling.
[0003] In the process of cooling by the flow of coolant, the coolant needs to be returned. In most cooling equipment, the coolant return channel is usually installed on the outside of the cooling tank. When the coolant flows out of the cooling tank and back into the return channel, leakage is likely to occur, which poses a safety hazard. Utility Model Content
[0004] In order to improve the cooling efficiency of the cooling box during use, this application provides a cooling box.
[0005] This application provides a cooling box, which adopts the following technical solution:
[0006] A cooling box includes a frame on which a box body is mounted. An inlet assembly for introducing coolant into the box body is also mounted on the frame. The box body is equipped with a coolant recovery and recirculation system. The recirculation system includes a first fixing plate, one side of which is mounted on the bottom surface of the box body, and the other side of which is mounted on the side wall of the box body. A drain hole is provided on the first fixing plate. A second fixing plate is mounted on the first fixing plate, and a third fixing plate is mounted on the second fixing plate. One end of the third fixing plate, away from the second fixing plate, is connected to the side wall of the box body. A drain outlet is also provided on the third fixing plate.
[0007] By adopting the above technical solution, the first fixing plate, the second fixing plate and the third fixing plate are set inside the box. The plates are connected to form a return channel, which reduces the flow distance of the coolant, facilitates rapid return, avoids the risk of coolant leakage from the box, and enhances the safety performance of the box.
[0008] In one specific implementation, the first fixing plate is an L-shaped folding plate.
[0009] By adopting the above technical solution, the L-shaped folding plate bending integrated molding design can enhance the connection effect between the plates, reduce the gaps formed when connecting the plates, and reduce the risk of leakage.
[0010] In one specific implementation, the end of the second fixing plate away from the first fixing plate is bent with a folded lug, and the third fixing plate is connected to the folded lug of the second fixing plate.
[0011] By adopting the above technical solution, one end of the second fixing plate is bent to form a folded ear, which facilitates the connection of the third fixing plate and also guides the coolant to flow towards the middle of the third fixing plate.
[0012] In one specific implementation, the third fixing plate is configured as a U-shaped plate.
[0013] By adopting the above technical solution, the third fixing plate is set as a U-shaped plate, which facilitates the installation of the third fixing plate and also prevents coolant from leaking from both sides of the third fixing plate.
[0014] In one specific implementation scheme, a sliding groove is formed on the third fixing plate, a guide rod is installed on the third fixing plate, the guide rod is disposed in the sliding groove, a sliding piece is installed on the guide rod, a spring is sleeved on the guide rod, one end of the spring is connected to the sliding piece, and the other end is connected to the third fixing plate, a limit strip is connected to the sliding piece, a positioning strip is installed on the third fixing plate, a filter plate is installed on the third fixing plate, and a first slot that engages with the limit strip and a second slot that engages with the positioning strip are formed on the filter plate.
[0015] By adopting the above technical solution, the positioning strip and the limiting strip are pressed against the filter screen plate to prevent the filter screen plate from deforming and bending during use, forming a gap with the third fixing plate. This prevents the coolant from flowing back through the gap between the filter screen plate and the third fixing plate, avoids the coolant from carrying impurities into the return system, and ensures that the coolant flows back from the filter screen plate, is filtered by the filter screen plate, and then flows back, which facilitates the cleaning of the coolant during the return process.
[0016] In one specific implementation, the inlet assembly includes an inlet main pipe mounted on the frame and disposed between the frame and the housing. An inlet branch pipe is connected to the inlet main pipe, and one end of the inlet branch pipe away from the inlet main pipe is connected to the housing.
[0017] By adopting the above technical solution, the coolant is filled into the main inlet pipe and then flows to the branch inlet pipes for distribution. Multiple branch inlet pipes are used to allow the coolant to flow into the tank from different positions, which facilitates the rapid and uniform filling of the tank with coolant.
[0018] In one specific implementation, a liquid distribution hood is installed inside the box, the inlet branch pipe is connected to the box at a position below the liquid distribution hood, and the liquid distribution hood has a diversion hole.
[0019] By adopting the above technical solution, the coolant will first flow into the distribution shroud after entering the tank, and then flow into the tank through the diversion holes on the distribution shroud. This makes it easier for the coolant to rise steadily at the same height in the tank, thus enhancing the heat dissipation effect.
[0020] In one specific implementation, a first support frame is installed on the frame, the first support frame is located at the four corners of the frame, and the first support frame is bent into an L-shaped plate; a second support frame is installed on the frame, the second support frame is arranged along the long side of the frame, and the second support frame is set as a V-shaped frame.
[0021] By adopting the above technical solution, the distance between the housing and the frame is raised by using the first support frame and the second support frame, the distance between the housing and the main inlet pipe is increased, the impact of the heat dissipated by the housing on the coolant in the main inlet pipe is reduced, and the coolant is prevented from being heated prematurely. The first support frame is set as an L-shaped folding plate and the second support frame is set as a V-shaped frame, which can enhance the support strength of the first support plate and the second support plate.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The first fixing plate, the second fixing plate and the third fixing plate are set inside the box. The plates are connected to form a return channel, which reduces the flow distance of the coolant, facilitates rapid return, avoids the risk of coolant leakage from the box and enhances the safety performance of the box.

[0034] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0035] This application discloses a cooling box, referring to... Figure 1 , Figure 2 and Figure 3 It includes a frame 1, a tank 2 for loading coolant is mounted on the frame 1, an inlet assembly 3 for inletting coolant into the tank 2 is mounted on the frame 1, and a cooling return system 4 is installed inside the tank 2.
[0036] A first support frame 11 is fixedly installed on the frame 1. The first support frame 11 is located at the four corners of the housing 2 and is bent into an L-shaped plate with an included angle of 90 degrees. A second support frame 12 is fixedly installed on the frame 1. The second support frame 12 is arranged along the long side of the frame 1 and is set as a V-shaped frame. The housing 2 is fixedly installed on the first support frame 11 and the second support frame 12.
[0037] Reference Figure 2 , Figure 3 and Figure 4 The inlet assembly 3 includes an inlet main pipe 31, which is fixedly installed on the frame 1. The inlet main pipe 31 is located between the housing 2 and the frame 1. Two or more inlet branch pipes 32 are connected to the inlet main pipe 31. The end of the inlet branch pipe 32 away from the inlet main pipe 31 is connected to the housing 2. The connection position between the inlet branch pipe 32 and the housing 2 is on the bottom wall of the housing 2. A liquid separator 33 is fixedly installed on the bottom surface inside the housing 2. The connection position between the inlet branch pipe 32 and the housing 2 is located below the liquid separator 33. A diversion hole 331 is opened on the liquid separator 33.
[0038] Coolant is introduced into the main inlet pipe 31 and then flows to the branch inlet pipes 32 for distribution. Multiple branch inlet pipes 32 distribute the coolant from different locations into the housing 2, facilitating rapid and even distribution. The first support frame 11 and the second support frame 12 raise the distance between the housing 2 and the frame 1, increasing the distance between the housing 2 and the main inlet pipe 31. This reduces the impact of heat dissipation from the housing 2 on the coolant in the main inlet pipe 31, preventing premature heating and enhancing cooling performance. After entering the housing 2, the coolant first flows into the distribution shroud 33 and then through the diversion holes 331 on the distribution shroud 33 into the housing 2, ensuring a stable rise of the coolant level within the housing 2 and enhancing heat dissipation.
[0039] Reference Figure 4 , Figure 5 and Figure 6 The housing 2 is integrally manufactured. A stepped surface 21 is integrally formed on one vertical side wall of the housing 2. The cooling reflux system 4 includes a first fixing plate 41, which is welded and fixedly installed inside the housing 2. The first fixing plate 41 has an L-shaped cross-section. One side of the first fixing plate 41 is welded to the stepped surface 21, and the other side is welded to the vertical side wall of the housing 2. A leakage hole 411 is provided on the first fixing plate 41. A second fixing plate 42 is welded to the first fixing plate 41. The second fixing plate 42 is vertically positioned, and the end of the second fixing plate 42 away from the first fixing plate 41 has a bent lug 421. A third fixing plate 43 is welded to the second fixing plate 42. The third fixing plate 43 has a U-shaped cross-section and is fixedly connected to the folded lug 421 of the second fixing plate 42. The end of the third fixing plate 43 away from the second fixing plate 42 is welded to the vertical side wall of the housing 2. The third fixing plate 43 is horizontally positioned and has a leakage outlet 431. (Refer to...) Figure 2 In this embodiment, the housing 2 is connected to an outlet pipe 22 for coolant to flow out, and the outlet pipe 22 is connected to the housing 2 between the first fixed plate 41 and the step surface 21.
[0040] The first fixing plate 41, the second fixing plate 42 and the third fixing plate 43 are set inside the housing 2. The bending between the plates forms a return channel, which reduces the flow distance of the coolant, facilitates rapid return, avoids the risk of coolant leakage from the housing 2, and enhances the safety performance of the housing 2.
[0041] Reference Figure 5 , Figure 7 , Figure 8 and Figure 9The third fixed plate 43 has a sliding groove 432. A guide rod 44 is fixedly installed on the third fixed plate 43 and is located in the sliding groove 432. A sliding piece 45 is slidably installed on the guide rod 44. A spring 46 is sleeved on the guide rod 44. One end of the spring 46 is fixedly connected to the sliding piece 45, and the other end is fixedly connected to the third fixed plate 43. A limit strip 47 is fixedly installed on the sliding piece 45, and there is a gap between the limit strip 47 and the third fixed plate 43. A positioning strip 48 is fixedly installed on the third fixed plate 43. A filter screen plate 49 is detachably installed on the third fixed plate 43 through the positioning strip 48 and the limit strip 47. The filter screen plate 49 has a first slot 491 that is engaged with the limit strip 47 and a second slot 492 that is engaged with the positioning strip 48.
[0042] When installing the filter plate 49 on the third fixing plate 43, first fasten the filter plate 49 onto the limiting strip 47, so that the limiting strip 47 falls into the first slot 491 on the filter plate 49. Then drag the filter plate 49 so that it is simultaneously fastened onto the positioning strip 48, so that the positioning strip 48 falls into the second slot 492 on the filter plate 49. When dragging the filter plate 49, the filter plate 49 will pull the sliding piece 45 to slide on the guide rod 44 and squeeze the spring 46. The thrust generated by the spring 46 pushes the limiting strip 47 to press against the filter plate 49, and at the same time pushes the filter plate 49 to press against the positioning strip 48. After the filter plate 49 is installed on the positioning strip 48 and the limiting strip 47, it is then fixed to the third fixing plate 43 at both ends by bolts. The positioning strip 48 and the limiting strip 47 are pressed against the filter screen plate 49 to prevent the filter screen plate 49 from deforming and bending during use, forming a gap with the third fixing plate 43. This prevents the coolant from flowing back through the gap between the filter screen plate 49 and the third fixing plate 43, avoids the coolant from carrying impurities into the return system, and ensures that the coolant flows through the filter screen plate 49 during return, is filtered by the filter screen plate 49, and then flows back, which facilitates the cleaning of the coolant during the return process.
[0043] The implementation principle of this application embodiment is as follows: The server chassis that needs to be cooled is placed in the chassis 2, and the coolant is filled into the main inlet pipe 31. The coolant flows from the main inlet pipe 31 to the branch inlet pipe 32 for diversion. The coolant flows into the chassis 2 from different positions using multiple branch inlet pipes 32. After flowing into the chassis 2, the coolant is diverted by the liquid distribution hood 33 and then flows through the server chassis to cool it down. After cooling, it flows to the third fixed plate 43. The coolant is filtered by the filter plate 49 on the third fixed plate 43. After filtration, the coolant flows to the first fixed plate 41 and then flows out of the chassis 2 through the outflow pipe 22, completing the rapid return flow.
[0044] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
