Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling cabinets, and in particular to a cabinet. Background Art

[0002] A liquid-cooled server cabinet is a device that uses liquid media to transfer heat and removes the heat generated by the server through a thermal conductor, thereby reducing the temperature of the server. By adopting liquid cooling technology, it effectively solves the limitations of traditional air-cooling methods in high-density server heat dissipation.

[0003] In the process of implementing this application, the inventors found that there are at least the following technical problems in the prior art:

[0004] Many existing devices are not equipped with special guide plates when they are built. Without guide plates, the internal layout of the cabinet is like an open maze. Once a leak occurs inside the cabinet, the liquid will flow freely and without direction, causing other components inside the equipment to be contaminated or damaged. It may also mistakenly enter the high-voltage area, which is the heart of electronic components and is responsible for energy conversion and transmission. Once liquid invades, it may cause circuit short circuits, equipment burns, and may even cause extreme situations such as fire or explosion. This not only affects the stability and reliability of the equipment, but also increases the risk of causing safety accidents, thereby reducing the overall quality and market competitiveness of the equipment.

The vertical distance between the first guide plate 31 located in the first heat dissipation zone 210a and the side of the box body 21 gradually increases from the first end 310 to the second end 311, so that it is tilted. The vertical distance between the first guide plate 31 located in the second heat dissipation zone 210b and the side of the box body 21 gradually increases from the third end 312 to the fourth end 313, so that it is tilted. Among them, the vertical distance between the fourth end 313 and the side of the box body 21 is not less than the vertical distance between the second end 311 and the side of the box body 21, so that the leaked liquid dripping from the first guide plate 31 of the first heat dissipation zone 210a can drip to the first guide plate 31 of the second heat dissipation zone 210b, and then drip from the first guide plate 31 of the second heat dissipation zone 210b, thereby improving the safety of the cabinet 100 and ensuring the normal operation of the cabinet 100.

The weak current box 5 is detachably connected to the strong current box 2 and is covered in the cavity 211, and the weak current box 5 is located on the side of the strong current box 2 facing the cabinet door.

[0052] The elastic rubber strip 6 is arranged at the connection between the weak current box 5 and the strong current box 2, so that the weak current box 5 and the strong current box 2 have an elastic buffer margin when they are assembled, which is convenient for assembly. The elastic rubber strip 6 ensures the sealing of the connection between the weak current box 5 and the strong current box 2, thereby reducing the risk of impurities such as dust and leakage entering the strong current box 2 and causing damage to the electronic components 22, thereby improving the safety performance of the cabinet 100.

[0053] There are two fans 4, which are respectively installed in the box 21, and each fan 4 is located in each heat dissipation zone. An air inlet 212 is provided at the bottom of the box 21. The fan 4 is used to drive air into the box 21 from the air inlet 212 and flow out from the heat dissipation holes 210c in the heat dissipation zone to take away the heat generated by the electronic components 22, thereby cooling the electronic components 22 and ensuring the normal operation of the electronic components 22. The guide component 3 can guide the hot air coming out of the fan 4, reducing the risk of the hot air coming out of the fan 4 dissipating into the cabinet 1, and improving the safety performance of the cabinet 100. The fan 4 can also blow the leaked liquid dripping from the guide component 3 to a direction away from the high-voltage box 2, further improving the safety performance of the cabinet 100, thereby ensuring the stability and reliability of the cabinet 100.

The bending portion 72 is connected to the side of the connecting portion 71 away from the strong current box 2, so that when the leaked liquid drips, the leaked liquid can be diverted to the side close to the strong current box 2, so that the leaked liquid can flow to the safe area through the first guide plate 31, wherein the bending direction of the bending portion can be designed according to needs and is not limited here.

[0057] In this embodiment, the second guide plate 7 is arranged at the top connection between the high-voltage box 2 and the low-voltage box 5. It can be understood that in other embodiments, the second guide plate 7 can also be arranged at the side connection and bottom connection between the high-voltage box 2 and the low-voltage box 5.
