This application claims priority to Chinese Patent Application No. 202310041558.3, titled “TOP COVER STRUCTURE FOR LIQUID COOLING BOX BODY OF DATA ROOM” and filed to the China National Intellectual Property Administration on Jan. 12, 2023, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the field of a liquid cooling box body, and more particularly, to a top cover structure for the liquid cooling box body of a data room.
Modern data centers undertake a large amount of data computation and storage, which requires increasingly higher system performance stability. To provide higher energy efficiency to meet needs for business development, heat dissipation of servers and even computer rooms has become crucial. As is well known, if the heat dissipation is poor, high temperature not only reduces operating stability of chips, but also generates excessive thermal stress due to temperature difference between internal environment and external environment of modules, which adversely affects electrical performance, operating frequency, mechanical strength, and reliability of the chips.
Compared to traditional air conditioning systems, the most popular liquid cooling technology in the current industry is more advantageous in solving the problem of “heat dissipation of data centers with high heat density”. This liquid cooling technology is quicker in temperature reduction, lower in energy consumption, and is most friendly to environment.
Liquid cooling refers to a cooling method that uses a liquid with higher specific heat capacity as a working fluid for heat transfer to meet needs for heat dissipation of IT equipment such as servers. Common liquid cooling technologies include immersion cooling, spray cooling, and cold plate cooling.
To ensure normal operation of a liquid cooling box body, it is required to ensure airtightness of the box body. This is because leakage of the liquid cooling box body may cause damage to key components such as chips, and also may cause serious damage to the liquids inside the box body, thus having severe consequences.
Most of the existing liquid cooling box bodies are provided with hinges or other small locking pieces for sealing. However, because areas that can be compressed are smaller and scattered, increasing the airtightness of the liquid cooling box bodies by increasing number of the locking pieces may lead to decrease in efficiency of opening and closing the liquid cooling box bodies for operation and maintenance staff.
Objectives of the present disclosure are to provide a top cover structure for a liquid cooling box body of a data room, which can increase efficiency of opening and closing the liquid cooling box body while ensuring its airtightness.
To achieve the above objectives, in one aspect the present disclosure provides a top cover structure for a liquid cooling box body of a data room, which at least includes a box body and a top cover. One side of the top cover is hinged with the box body and can cover an opening of the box body. Each of the top cover and the box body is provided with a clamping piece that can be clamped to a connecting piece. When two ends of the connecting piece are respectively clamped to the two clamping pieces positioned on the top cover and the box body, a downward pressure applied to the top cover can be provided.
As a further improvement of the above technical solutions, the connecting piece is provided with a bending structure fitting with an edge of the box body, such that the connecting piece can come into contact with an outer wall of the box body.
As a further improvement of the above technical solutions, the clamping piece at least includes a fastener having a clamping slot for clamping an end of the connecting piece.
As a further improvement of the above technical solutions, the clamping piece positioned on the box body also includes a supporting part, where the supporting part is rotatably arranged on the box body, and a free end of the supporting part is connected to the fastener, such that a preset distance exists between the fastener and a side wall of the box body.
As a further improvement of the above technical solutions, the preset distance is greater than a width of the fastener.
As a further improvement of the above technical solutions, a sealing platform is provided around the opening of the box body, and a bottom surface of the sealing platform is provided with a mounting rack, where the mounting rack has a bearing space for placement of a clamping piece mounting plate, an end of the clamping piece mounting plate is provided with a clamping piece connecting plate extending towards an outer wall of the sealing platform, and the clamping piece is arranged on the clamping piece connecting plate.
As a further improvement of the above technical solutions, a size of the top cover matches the sealing platform, and a side wall of the sealing platform is flush with a side wall of the top cover.
As a further improvement of the above technical solutions, the top cover is at least provided with two clamping pieces, and the two clamping pieces are symmetrically arranged with a central axis of the top cover as a reference mirror.
As a further improvement of the above technical solutions, a spacing exists between the two clamping pieces positioned on the top cover, and the spacing is greater than twice the preset distance.
As can be seen, in the technical solutions provided by the present disclosure, each of the box body and the top cover is provided with a clamping piece that can be clamped to a connecting piece. In this way, when the two ends of the connecting piece are respectively clamped to the two clamping pieces positioned on the same side of the box body, a downward pressure can be provided to most areas of the top cover to compress the top cover to prevent gas and liquid from flowing out of the box body, thereby improving airtightness of the liquid cooling box body.
Furthermore, a preset distance greater than the width of the fastener exists between the fastener of the clamping piece and the box body, such that the connecting piece can be detached from or clamped to the clamping piece on the top cover through horizontal movement, which improves convenience of using the connecting piece, thereby increasing efficiency of opening and closing the top cover.

In an implementable embodiment, as shown in
Specifically, the box body 1 is a hollow structure with an opening facing upwards to ensure that a server can be placed in the box body 1. The box body 1 is filled with non-conducting liquid, which immerses the server and cools the server. A size of the top cover 2 matches the box body 1, and the top cover 2 can rotate above the opening of the box body 1. When the top cover 2 comes into contact with the box body 1, the top cover 2 can cover the opening of the box body 1 to prevent the liquid from flowing out of the box body 1.
In this embodiment, the clamping piece 4 at least includes a fastener, which is C-shaped or in other shape with a clamping slot. The clamping slot on the top cover 2 faces towards an upper surface of the top cover 2, and the clamping slot on the box body 1 faces towards a side wall of the box body 1, making it not easy for the connecting piece 3 clamped into the clamping slot to move and break away.
In practical applications, the top cover 2 is at least provided with two clamping pieces 4, and the two clamping pieces 4 are symmetrically arranged with a central axis of the top cover 2 as a reference mirror, such that the two connecting pieces 3 clamped to the two clamping pieces 4 can cover most of area of the top cover 2. In this way, stressed area of the top cover 2 increases, which can further reduce the spacing between the top cover 2 and the box body 1.
Further, number of the clamping pieces 4 arranged on the box body 1 corresponds to that of the clamping pieces 4 arranged on the top cover 2, and these clamping pieces 4 are positioned on a same center line. The two clamping pieces 4 on the same side of the box body 1 can be clamped through the same connecting piece 3. In order that the connecting piece 3 can be clamped into the fasteners of the two clamping pieces 4, a downward pressure may be applied to the top cover 2 such that the top cover 2 gets close to the box body 1, thereby achieving unilateral compression of the box body 1.
Further, the connecting piece 3 is L-shaped or in other shape that can match the structure of the box body 1. The L-shaped bending structure can match the edge of the box body 1, such that the connecting piece 3 comes into contact with the outer wall of the box body 1, thereby improving stability of the connecting piece 3 clamped.
In an implementable embodiment, the clamping piece 4 positioned on the box body 1 also includes a supporting part, where the supporting part is rotatably arranged on the box body 1, and a free end of the supporting part is connected to the fastener. A length of the supporting part is greater than the width of the fastener. In this way, after the supporting part rotates, a preset distance exists between the fastener and the side wall of the box body 1, and the preset distance is greater than the width of the fastener.
Specifically, when the operation and maintenance staff need to open the top cover 2, they move horizontal parts of the connecting pieces 3 towards a direction away from the clamping piece 4 on the top cover 2. That is, the horizontal parts of the two connecting pieces 3 move relatively. Because the preset distance is greater than the width of the fastener, the supporting part rotates such that the end of the connecting piece 3 can completely break away from the fastener. In this case, the operation and maintenance staff only need to flip the connecting piece 3 that is separated from the clamping piece 4 at one end, such that the connecting piece 3 gets away from the top cover 2. In this way, the top cover 2 can be opened.
In a natural state, one end of the connecting piece 3 is still clamped to the clamping piece 4 on the box body 1, the free end of the supporting part faces downwards, and it is not required to remove the connecting piece 3 wholly.
After the top cover 2 is closed, the operation and maintenance staff first rotate the supporting part such that its free end faces upwards, making it easier for other end of the connecting piece 3 to clamp with the clamping piece 4 on the top cover 2. In this case, the horizontal part of the connecting piece 3 comes into contact with an upper surface of the box body 1, thereby compressing the top cover 2 by the connecting piece 3.
Further, a spacing exists between the two clamping pieces 4 positioned on the top cover 2, and the spacing is greater than twice the preset distance. In this way, when the operation and maintenance staff move the two connecting pieces 3 relative to each other, the spacing can ensure that no collision occurs between the two connecting pieces 3, thereby avoiding mutual influences.
Different from the embodiment where the clamping pieces 4 are fixed on two sides of the box body 1, referring to
In practical applications, to ensure that the clamping piece connecting plate 6 can attach to the sealing platform 7, thereby improving clamping stability between the connecting piece 3 and the clamping piece 4, the clamping piece connecting plate 6 is provided with a bending structure fitting with an edge of the sealing platform 7. Further, the size of the top cover 2 matches that of the sealing platform 7. While the bottom surface of the top cover 2 covers the opening of the box body 1, the top cover 2 can also fit with the sealing platform 7, such that the side wall of the sealing platform 7 is flush with the side wall of the top cover 2. In this way, when the connecting piece 3 is clamped to the two clamping pieces 4 on the same side, it does not lead to a consequence that failure of clamping is caused by insufficient length of the connecting piece 3 due to far distance between the top cover 2 and the sealing platform 7.
The embodiments set forth above are only illustrated as preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. All modifications, equivalent substitutions and improvements made within the spirit and principles of the present disclosure shall fall within the protection scope of the present disclosure.
