Description

Technical Field

[0001] This application relates to the field of liquid-cooled heat sinks, and more particularly to a high-efficiency liquid-cooled heat sink for data center servers. Background Technology

[0002] A liquid-cooled heatsink is a type of cooling system that uses an internal fan to draw hot air from the rear of the server into a liquid cooling cabinet. The hot air is then cooled by internal water pipes, and the cooled air is blown to the front of the server. The hot water then flows back to the outside. This continuous circulation process achieves the cooling effect. As data centers grow larger and larger, their heat generation also increases. To ensure timely heat dissipation and normal operation of data centers, liquid-cooled heatsinks are currently used for heat dissipation.

[0003] The prior art relates to a liquid-cooled heat dissipation cabinet for data centers, as shown in the reference. Figure 1 The cabinet includes a main body (1), and the outer wall of the main body (1) is provided with a heat dissipation vent (11). A cooling fan (12) is installed in the cabinet to dissipate the heat generated in the main body (1) in a timely manner. When working, the cooling fan (12) is turned on, and the cooling fan (12) can dissipate the heat generated after liquid cooling exchange in a timely manner into the main body (1), thereby making the heat dissipation effect more stable.

[0004] Regarding the aforementioned technologies, the inventors believe that in current water-cooled server racks, when the exhaust fan dissipates hot air from inside the rack, the static electricity causes dust to adhere to the air outlet of the heat dissipation fins. Over time, excessive dust accumulation can clog the air outlet, affecting the heat dissipation efficiency of the water-cooled server rack, and therefore needs to be improved. Summary of the Invention

[0005] To improve the heat dissipation efficiency of water-cooled cabinets, this application provides a high-efficiency liquid-cooled heat dissipation cabinet for data center servers.

[0006] The high-efficiency liquid-cooled heat dissipation cabinet for data center servers provided in this application adopts the following technical solution:

[0007] A high-efficiency data center server liquid-cooled heat dissipation cabinet includes a cabinet body. The outer wall of the cabinet body has a plurality of heat dissipation vents. A mounting plate is provided on the side wall of the cabinet body with the heat dissipation vents. A cleaning component is provided on the mounting plate. The cleaning component includes a cleaning plate, a cleaning brush, and a moving part. The cleaning brush is connected to the cleaning plate and abuts against the side wall of the cabinet body with the heat dissipation vents. The moving part is provided on the mounting plate and is used to drive the cleaning plate to move.

[0008] By adopting the above technical solution, heat dissipation vents are provided on the side wall of the main body of the cabinet, which can dissipate heat from the main body of the cabinet in a timely manner. A cleaning component is installed on the side of the cabinet with heat dissipation vents. After the cleaning plate is moved, the cleaning brush can sweep away the dust on the surface of the main body of the cabinet, thereby reducing the phenomenon of dust adhering to the heat dissipation vents and causing blockage.

[0009] Preferably, each of the heat dissipation vents has a heat dissipation blade rotatably connected to its inner wall, and the main body of the cabinet is provided with a drive component for driving the heat dissipation blades to open and close.

[0010] By adopting the above technical solution, the heat dissipation blades are driven to close the corresponding heat dissipation vents when the outside temperature is low. There is no need for the water-cooled chassis to dissipate heat inside, and the heat dissipation vents can be closed, thereby reducing the entry of external impurities into the cabinet body and thus reducing the impact on the internal cleanliness of the cabinet body.

[0011] Preferably, the driving component includes a first connecting rack, a driving rod, a driven rod, a first driving bevel gear, a first driven bevel gear, a first rotating gear, a synchronizing element, a first connecting worm gear, a first connecting plate, and a plurality of first abutting rods. The side wall of the cabinet body with the heat dissipation vent has a first reciprocating groove. The first connecting rack is inserted into the first reciprocating groove and can move within it. Each first abutting rod corresponds to a heat dissipation blade. The driving rod is located on the side wall of the cabinet body with the heat dissipation vent, and passes through the mounting plate and connects with the first connecting rod. The connecting worm gear is used to rotatably connect the active rotating rod to the mounting plate; the first active bevel gear is sleeved on the active rotating rod, the first driven bevel gear meshes with the first active bevel gear, the first driven bevel gear is sleeved on the driven rotating rod, and the first rotating gear is sleeved on the driven rotating rod and meshes with the first connecting rack; the first connecting plate is connected to the first connecting rack, and all the first abutting rods are disposed on the side of the first connecting plate near the heat dissipation port, each of the first abutting rods abuts against the corresponding heat dissipation blade, and the length of the first abutting rod is greater than the horizontal distance from the first connecting plate to the heat dissipation blade.

[0012] By adopting the above technical solution, after the active rotating rod rotates, it causes the driven rotating rod to drive the first rotating gear to rotate, thereby causing the first connecting rack to move. At this time, the first abutting rod at the connecting plate rises or falls. After the first connecting rack rises, the first abutting rod that abuts against the heat dissipation blade moves, causing the heat dissipation blade to rotate, thereby opening the heat dissipation port. When the first connecting rack falls, the first abutting rod moves away from the rotation point of the heat dissipation blade, thereby causing the heat dissipation blade to rotate and close the heat dissipation port.

[0013] Preferably, the synchronizing element includes a second rotating gear, a second connecting rack, a second connecting plate, and a plurality of second abutting rods. The second rotating gear is sleeved on the driven rotating rod. The side wall of the cabinet body with the heat dissipation vent has a second reciprocating groove. The second connecting rack is inserted into the second reciprocating groove and can slide in the second reciprocating groove. Each heat dissipation blade corresponds to a second abutting rod. The second rotating gear and the second connecting rack mesh with each other. The second connecting rack is inserted into the second reciprocating groove. All the second abutting rods are located on the side of the second connecting plate near the heat dissipation vent. Each second abutting rod abuts against the corresponding heat dissipation blade. The length of the second abutting rod is equal to the length of the first abutting rod.

[0014] By adopting the above technical solution, when the driven rotating rod rotates, the first rotating gear and the second rotating gear rotate synchronously, and the first connecting rack and the second connecting rack move synchronously. The first abutting rod and the second abutting rod rise or fall simultaneously, jointly supporting the corresponding heat dissipation blades, thereby improving the stability of the heat dissipation blades when they rotate to open the heat dissipation port.

[0015] Preferably, the heat dissipation blades are provided with a first clearance groove and a second clearance groove on the side near the heat dissipation fan. The first abutment rod is inserted into the first clearance groove, and the second abutment rod is inserted into the second clearance groove. Both the first clearance groove and the second clearance groove are inclined and parallel to each other.

[0016] By adopting the above technical solution, the first abutting rod is inserted into the first clearance groove, so that both the first abutting rod and the second abutting rod abut against the corresponding heat dissipation blades. At the same time, the heat dissipation blades can close the heat dissipation opening, improving the sealing performance of the heat dissipation blades to the heat dissipation opening and further reducing the occurrence of external impurities entering the main body of the cabinet.

[0017] Preferably, the moving component includes a drive motor, a rotating rod, a connecting worm gear, a second connecting worm, a second driving bevel gear, a second driven bevel gear, and a drive screw; the mounting plate is provided with a positioning plate, the positioning plate is connected to the drive motor, one end of the rotating rod is connected to the coupling of the drive motor, the other end of the rotating rod is connected to the connecting worm gear, the connecting worm gear can mesh with the second connecting worm, the surface of the mounting plate is provided with a drive groove, the drive screw is inserted into the drive groove, one end of the drive screw is rotatably connected to the end wall of the drive groove, the other end of the drive screw passes through the drive groove and is connected to the second driving bevel gear, the second driven bevel gear meshes with the second driving bevel gear, and the second connecting worm is connected to the second driven bevel gear.

[0018] By adopting the above technical solution, after the connecting worm gear meshes with the second connecting worm, the drive motor is started, and the rotating rod drives the connecting worm gear to rotate, thereby causing the second connecting worm to drive the second driven bevel gear to rotate. The second driving bevel gear rotates synchronously with the drive screw, thereby enabling the cleaning plate to move along the length direction of the drive groove, and thus enabling the cleaning bristles to clean the cabinet body.

[0019] Preferably, the mounting plate has an adjustment groove, in which an adjustment screw is inserted. One end of the adjustment screw is rotatably connected to the inner wall of the adjustment groove, and the other end of the adjustment groove is provided with a forward and reverse motor. The other end of the adjustment screw is connected to the coupling of the forward and reverse motor. The positioning plate is sleeved on the adjustment screw and fits against the inner wall of the adjustment groove.

[0020] By adopting the above technical solution, after starting the forward and reverse motors, the adjusting block can move along the length of the adjusting screw, and the connecting worm gear can mesh with the first connecting worm, thereby enabling the active rotating rod to rotate, and thus the heat dissipation blades to open or close.

[0021] Preferably, the cabinet body has a connecting rod inside, a tension spring is provided at the connecting rod, one end of the tension spring is connected to the connecting rod, and an operating rod is provided at the other end of the tension spring. A barrier film is sleeved on the connecting rod, and the other end of the barrier film is connected to the operating rod. An operating groove is provided on the side wall of the cabinet column, and the operating rod passes through the operating groove.

[0022] By adopting the above technical solution, when cleaning the surface of the cabinet body, pulling down the operating lever allows the barrier film to isolate the heat dissipation vents from the inside of the cabinet body. This effectively reduces the occurrence of dust and impurities entering the cabinet body and affecting the cleanliness of the cabinet body's interior when the cleaning components are cleaning the surface of the cabinet body.

[0023] Preferably, the side wall of the cabinet body is provided with a locking hook, which can be engaged with the operating lever.

[0024] By adopting the above technical solution, pulling the operating rod will cause the locking hook to engage with the operating rod, thereby positioning the operating rod and improving the stability of the barrier film.

[0025] Preferably, a limiting groove is provided on the side wall of the cabinet body away from the operating slot, the operating rod passes through the limiting groove, a guide rod is provided on the side wall of the cabinet body, the operating rod is sleeved on the guide rod, and the guide rod is slidably connected to the operating rod.

[0026] By adopting the above technical solution, when the operating lever moves, it slides on the outer wall of the guide rod, which makes the operating lever more stable when rising or falling, thereby improving the barrier film's barrier performance to the inside of the cabinet body.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. A cleaning component is installed on the side wall of the main body of the cabinet where the heat dissipation vents are opened. The cleaning brush can remove dust and other impurities from the liquid cooling cabinet, thereby reducing the occurrence of dust and other impurities clogging the heat dissipation vents and improving the cleaning performance of the liquid cooling cabinet.

[0029] 2. Each heat dissipation vent corresponds to a heat dissipation blade. The driving component can make the heat dissipation blade close the heat dissipation vent. When the cleaning component is cleaning the main body of the cabinet, the driving component first closes the heat dissipation vent with the heat dissipation blade, and then the cleaning component cleans the main body of the cabinet. This can effectively reduce the phenomenon of dust and other impurities entering the main body of the cabinet.

[0030] 3. Before cleaning the main body of the cabinet, pull the operating lever so that the barrier film blocks the heat dissipation vents from the cooling fan, thereby further reducing the occurrence of dust and impurities entering the main body of the cabinet. Attached Figure Description
