[0002] A cabinet is an independent or self-supporting housing for accommodating electrical or electronic equipment. It is generally equipped with doors, detachable or non-detachable side panels and back panels. It is an indispensable component of electrical equipment and a carrier of electrical control equipment. It is generally made of cold-rolled steel plates or alloys, and can provide waterproof, dustproof, and electromagnetic interference protection for stored equipment. Cabinets are generally divided into server cabinets, network cabinets, console cabinets, etc. In some special environments, the cabinet needs to cool the equipment in the cabinet to ensure its normal operation. Liquid cooling is inexpensive and has good heat dissipation effect, so it is widely used in cabinets to cool equipment;

[0032] like Figures 1 to 9 As shown, the utility model is a liquid-cooled cabinet, comprising: an installation frame 1, a cabinet body 14, a refrigeration mechanism for cooling the cooling liquid, and a cooling mechanism for driving the cooling liquid to cool the inside of the cabinet body 14;

[0033] The refrigeration mechanism includes: a semiconductor refrigeration sheet 3 for cooling the coolant in the inner cavity of the cooling box 2, and two groups of semiconductor refrigeration sheets 3 are provided, which are respectively attached to the side walls of the cooling box 2, and a stirring component is used to stir the coolant in the inner cavity of the cooling box 2; when the semiconductor refrigeration sheet 3 is started, the coolant in the inner cavity of the cooling box 2 can be cooled by the semiconductor refrigeration sheet 3, and the coolant can be stirred by starting the stirring mechanism, which speeds up the mixing of the coolant, so that the coolant is fully cooled, the cooling effect is improved, and it is beneficial to the subsequent cooling of the inside of the cabinet 14.

[0034] The stirring assembly includes: a stirring member 1 for stirring the coolant in different directions, the stirring member 1 stirs the coolant along the depth direction of the cooling box 2, a stirring member 2, the stirring member 2 stirs the coolant along the length direction of the cooling box 2, and an S-shaped slide guide for guiding the swing path of the stirring member 2; the stirring member 1 includes: a movable frame 11 for stirring the coolant, the movable frame 11 is movably installed in the inner cavity of the cooling box 2, and a driving unit drives the movable frame 11 to move; the driving unit includes: the cooling box 2 fixedly installed at the bottom of the inner cavity of the installation frame 1, a threaded rod 8 rotatably installed on the side wall of the cooling box 2, a motor 7 that drives the threaded rod 8 to rotate, a movable plate 9 that drives the movable frame 11 to move along the axis of the threaded rod 8, the movable plate 9 is threadedly installed on the outer edge of the threaded rod 8, and a limit rod 10 is used to limit the movable plate 9 when it moves, and both ends of the limit rod 10 are fixedly installed on the inner wall of the cooling box 2.

[0035] When the coolant is stirred, the motor 7 is started to rotate forward and reversely, which drives the threaded rod 8 to rotate, and the threaded rod 8 drives the movable plate 9 to move. Under the limiting action of the limiting rod 10, the movable plate 9 can move back and forth up and down with the forward and reverse rotation of the threaded rod 8, thereby driving the movable frame 11 to move back and forth up and down, so that the movable frame 11 stirs the coolant along the depth direction of the cooling box 2, thereby mixing the coolant in the depth direction, and stirring the coolant from the bottom to the top of the cooling box 2, ensuring sufficient cooling of the coolant and improving the cooling effect.

[0036] The second stirring member includes: multiple groups of stirring plates 13 for stirring the coolant, the stirring plates 13 are rotatably mounted on the inner wall of the cooling box 2, and the connecting rod 12 is fixedly mounted on the side wall of the stirring plates 13, and one end of the connecting rod 12 is slidably mounted in the inner cavity of the S-shaped slide groove 15; the S-shaped slide groove 15 is opened on the inner wall of the movable frame 11 along the moving direction of the movable frame 11, and the S-shaped slide groove 15 is a uniformly corrugated groove with a certain depth and width. The diameter of the connecting rod 12 is smaller than the width of the S-shaped slide groove 15, so that the connecting rod 12 can shake while sliding along the inner cavity of the S-shaped slide groove 15. In addition, multiple groups of S-shaped slide grooves 15 are opened on the inner wall of the movable frame 11, and are symmetrically and evenly distributed on the inner wall of the movable frame 11.

[0037] When the rectangular movable frame 11 moves along the depth direction of the cooling box 2, the S-shaped groove 15 on the inner wall of the movable frame 11 guides the connecting rod 12 along the moving direction of the movable frame 11, which can drive the connecting rod 12 to move, and the connecting rod 12 drives the stirring plate 13 to move. Since the stirring plate 13 is rotatably installed on the inner wall of the cooling box 2, when one end of the connecting rod 12 slides along the inner cavity of the S-shaped groove 15, it can drive the stirring plate 13 to swing back and forth laterally. Since multiple groups of stirring plates 13 swing back and forth laterally synchronously, the coolant can be stirred along the length direction of the cooling box 2, thereby realizing the mixing of the coolant in the horizontal direction, ensuring sufficient cooling in the coolant, and further improving the cooling effect.

[0038] The above-mentioned mechanism in the present application stirs the coolant synchronously along the depth direction and the length direction of the cooling box 2, which can mix the coolant in the depth direction and stir the coolant from the bottom to the top of the cooling box 2 to ensure sufficient cooling of the coolant and improve the cooling effect. It can also mix the coolant in the horizontal direction to ensure sufficient cooling of the coolant and further improve the cooling effect, so that the coolant circulating out of the cabinet 14 can be fully cooled, thereby fully performing liquid cooling on the equipment in the cabinet 14, thereby improving the heat dissipation cooling efficiency of the cabinet 14.

[0039] The cooling mechanism includes: a storage box 4 fixedly installed at the bottom of the inner cavity of the installation frame 1, a liquid inlet pipe plugged and installed on the top of the storage box 4, a pump body 6 for transporting the cooling liquid in the inner cavity of the storage box 4, and a circulation pipe 5 for circulating the cooling liquid to the inner cavity of the cabinet 14 for cooling. A connecting pipe is plugged and installed between the cooling box 2 and the storage box 4. The other end of the circulation pipe 5 is plugged and installed on the side wall of the cooling box 2. A certain amount of cooling liquid is transported to the inner cavity of the storage box 4 through the liquid inlet pipe. When the cabinet 14 is cooled down, the pump body 6 is started to transport the cooling liquid inside the storage box 4 to the inner cavity of the circulation pipe 5 through the pump body 6. The cooling liquid is circulated to the inside of the cabinet 14 through the circulation pipe 5 for cooling down. The cooling liquid after the cooling down of the inside of the cabinet 14 flows into the cooling box 2 The inner cavity is refrigerated, and the refrigerated coolant flows into the inner cavity of the storage box 4 through the connecting pipe for re-circulation. Since the connecting end of the circulation pipe 5 and the cooling box 2 is located near the bottom of one side of the cooling box 2, and the connecting pipe is located near the top of the other side of the cooling box 2, when the coolant after cooling the inside of the cabinet 14 flows into the inner cavity of the cooling box 2, the liquid level of the coolant in the inner cavity of the cooling box 2 rises to the connecting pipe, it can flow into the inner cavity of the storage box 4 through the connecting pipe, so that the coolant stays in the inner cavity of the cooling box 2 for a certain period of time. In conjunction with the refrigeration mechanism, the coolant can be refrigerated for a certain period of time, and then the coolant can be fully refrigerated and then circulated to cool the cabinet 14, thereby ensuring the cooling effect of the cabinet 14.

[0040] It should be added here that the part of the circulation pipe 5 in the inner cavity of the cabinet 14 is designed in a serpentine shape, and the outer arc surface of the serpentine section of the circulation pipe 5 is installed with heat-absorbing fins, and the outer side surface of the heat-absorbing fins is fixedly installed with heat-conducting plates. When the coolant passes through the serpentine section of the circulation pipe 5, the heat-absorbing fins and the heat-conducting plates cooperate with each other to fully dissipate liquid cooling for the equipment in the cabinet 14.

[0041] Working principle: When in use, a certain amount of coolant is transported to the inner cavity of the storage box 4 through the liquid inlet pipe. When the cabinet 14 is cooled, the coolant inside the storage box 4 is transported to the inner cavity of the circulation pipe 5 through the pump body 6. The coolant is circulated to the interior of the cabinet 14 through the circulation pipe 5 for cooling. The coolant after cooling inside the cabinet 14 flows into the inner cavity of the cooling box 2, and the coolant is cooled by the refrigeration mechanism. The cooled coolant flows into the inner cavity of the storage box 4 through the connecting pipe for recirculation to cool the cabinet 14.
