[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] As shown in the accompanying drawings, a liquid cooling cabinet with heat dissipation and airtight protection functions includes a cabinet body 1, and the cabinet body 1 is a rectangular hollow box structure with an open front end; a partition 2 is arranged in the cabinet body 1, and flow channels are arranged on the top plate, bottom plate, left plate, right plate of the cabinet body 1 and inside the partition 2, and the flow channels inside the top plate, bottom plate, left plate, right plate of the cabinet body 1 and the flow channels inside the partition 2 together constitute a cooling liquid channel, and a first pipe joint 3 and a second pipe joint 4 are installed on the outer wall of the right side plate of the cabinet body 1; the first pipe joint 3 is connected to the water inlet of the cooling liquid channel; the second pipe joint 4 is connected to the water outlet of the cooling liquid channel; a door panel 5 is installed on the front end face of the cabinet body 1; and a plurality of fans 6 are arranged on the rear panel of the cabinet body 1.

[0042] By adopting the above structure, when in use, the first pipe joint and the second pipe joint are respectively connected to the liquid inlet pipe and the liquid outlet pipe of the coolant circulation device (not shown in the figure). The coolant enters the coolant channel from the first pipe joint, and then flows out from the second pipe joint, thereby playing a role in cooling and heat dissipation. The coolant circulation device is a conventional prior art and will not be described in detail here. Since the coolant passes through the flow channels inside the top plate, bottom plate, left plate, and right plate of the cabinet 1 and the flow channels inside the partition 2, the coolant channel does not occupy the internal space of the cabinet. The top plate, bottom plate, left plate, right plate of the cabinet 1, and the partition 2 all form cold plates. When the coolant in the coolant channel is circulating, each cold plate exchanges heat with the heat in the cabinet 1, and the heat inside the cabinet 1 is taken away by the coolant.

[0043] In this embodiment, the flow channels inside the top plate, bottom plate, left plate, right plate, and the flow channels inside the partition plate of the cabinet 1 are all "S"-shaped tortuous flow channels, and in order to reduce the fluid flow resistance, the flow channel surface roughness is required to be Ra0.8.

By providing the shielding sealing strip 7, the functions of rainproof, sand and dustproof and electromagnetic shielding of the liquid cooling cabinet are realized.

[0045] Combination Figure 1 As shown, for the convenience of maintenance and disassembly, the door panel 5 is detachably connected to the cabinet body 1 by screws 8. Specifically, the screws 8 are M6 captive screws, and the captive screws are installed on the door panel 5. When the door panel 5 is disassembled, the captive screws do not withdraw from the door panel 5, which can prevent the screws 8 from falling or being lost.

[0046] Combination Figure 1 , Fig.11 As shown, in order to enhance the heat dissipation conduction of the cabinet 1, heat dissipation teeth 1c are respectively provided on the inner surfaces of the top plate, the left plate and the right plate of the cabinet 1.

[0048] Combination Fig.12 , Fig.13 and Fig.15 As shown, when installing the electrical equipment chassis 10, in order to position and guide the electrical equipment chassis 10, two positioning pins 13 are provided on the support baffle 11, and two positioning seats 14 are provided on the rear panel of the electrical equipment chassis 10; when the electrical equipment chassis 10 is pushed backward, the positioning pins 13 are inserted into the pin holes of the positioning seats 14. The front end of the positioning pins 13 is provided as a guide cone to play a guiding role. Therefore, the positioning and guiding of the electrical equipment chassis 10 are achieved by using the structure of the positioning pins 13 and the positioning columns 14.

[0049] Combination Figure 1 and Fig.14 As shown, a locker 16 is provided on the bottom plate of the bracket 9; a handle 17 is provided on the front panel of the electrical equipment chassis 10; the handle 17 and the locker 16 are locked with each other, so that the electrical equipment chassis 10 can be fixed. Furthermore, the locker 16 includes a connecting column 16a, a U-shaped block 16b and a locking pin 16c; the connecting column 16a is screwed to the bottom plate of the bracket 9, the U-shaped block 16b is fixed to the front end surface of the connecting column 16a, and the locking pin 16c is laterally inserted into the two side plates of the U-shaped block 16b; the handle 17 includes a handle base 17a and a locking member 17b arranged on the handle base 17a; the locking member 17b is installed in the groove of the handle base 17a through a pin shaft 17c; the lower end of the locking member 17b is integrally formed with a locking hook 17d; when the handle 17 and the locker 16 are locked with each other, the locking hook 17d extends into the U-shaped block 16b and hooks on the locking pin 16c.
