Description

Technical Field

[0001] The utility model relates to the technical field of battery box bracket equipment, in particular to a liquid cooling box battery rack bracket. Background Art

[0002] Battery packs often generate a lot of heat when working, and the battery itself has weak high temperature resistance. In order to install a large number of battery packs in the same place as energy storage equipment, battery box manufacturers usually install liquid cooling tubes and battery racks in the battery liquid cooling box. On the one hand, by adding coolant to the liquid cooling tubes, the battery can be cooled; on the other hand, multiple battery packs are arranged in order through the battery rack to maintain internal temperature balance.

[0003] However, the liquid cooling tube of the battery cabinet often vibrates irregularly when working due to the following factors, which may affect or even damage the battery:

[0004] a) Fluid dynamics effect: The liquid flowing in the liquid cooling tube may produce fluid dynamics effect, causing the tube to vibrate;

[0005] b) Pump operation: The operation of the pump in the liquid cooling system may generate mechanical vibration, causing pipeline vibration;

[0006] c) Temperature change: The battery cabinet generates heat during operation, and the liquid cooling system dissipates heat by circulating coolant.

[0007] Therefore, in order to prevent the irregular shaking of the liquid cooling pipes in the battery cabinet from affecting the internal batteries, a buffer needs to be designed for the liquid cooling pipe system. However, the space in the battery cabinet is limited. Adding a large number of additional pipe buffer structures will, on the one hand, increase the size of the overall equipment, and on the other hand, make it inconvenient for inspection, maintenance and replacement. Utility Model Content

[0008] The utility model aims to solve the problem that the irregular shaking of the liquid cooling tube in the battery cabinet affects the normal operation of the internal batteries, and proposes a liquid cooling box battery rack support plate.

[0017] A liquid inlet vertical pipe and a liquid outlet vertical pipe are respectively arranged at the suspended positions outside the two groups of columns on both sides of the battery frame, and the sides of the liquid inlet vertical pipe and the liquid outlet vertical pipe are both connected with a hose.

[0018] As a further description of the above technical solution:

[0019] The bottom end of the liquid inlet vertical pipe is connected to a liquid inlet main pipe, and one end of the liquid inlet main pipe away from the liquid inlet vertical pipe is connected to a liquid cooling inlet pipe;

[0020] The bottom end of the liquid outlet vertical pipe is connected to a liquid outlet main pipe, and one end of the liquid outlet main pipe away from the liquid outlet vertical pipe is connected to a liquid cooling outlet pipe;

[0021] The liquid cooling inlet pipe and the liquid cooling outlet pipe are arranged in parallel and are both arranged perpendicular to the truss.

[0022] As a further description of the above technical solution:

[0023] Each group of columns is provided with three columns, and partition strips are provided at the joints between the truss and the columns among the three columns.

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

[0039] See also Figure 1-4The utility model provides a technical solution: a liquid cooling box battery rack support plate, comprising at least two groups of columns 1 and a plurality of equidistantly arranged trusses 2 connected between any two adjacent columns 1 in each group of columns 1, each group of columns 1 includes at most three columns 1, and a first guide bar 21 is arranged at the joint between the truss 2 and the columns 1 at both ends of each group of columns 1; the first guide bar 21 includes a horizontally arranged straight bar 211 and a bending bar 212 connected to the straight bar 211, and the bending bar 212 extends upward along one end close to the straight bar 211 toward the other end; a second guide bar 22 is also arranged on the truss 2, and the second guide bar 22 is arranged parallel to the straight bar 211; a battery rack 3 is arranged above the truss 2, and the battery rack 3 is slidably plugged with the first guide bar 21 and the second guide bar 22;

[0040] Among them, the setting of the first guide bar 21 and the second guide bar 22 is used to stably limit the battery rack 3 on the truss 2 to prevent excessive shaking during transportation or certain specific working conditions, which may affect the internal battery equipment; and the coordinated use of the straight bar 211 and the bending bar 212 allows multiple battery racks 3 to be installed on the truss 2 from the bending bar 212 by pushing them inward obliquely, and no additional installation and fixing workpieces are generated in the overall equipment, which facilitates installation and reduces the installation process.

[0041] Specifically, Figure 2 As shown, a liquid inlet vertical pipe 42 and a liquid outlet vertical pipe 52 are respectively arranged at the suspended positions on the outer sides of the two groups of columns 1 on both sides of the battery frame 3, and the sides of the liquid inlet vertical pipe 42 and the liquid outlet vertical pipe 52 are connected with a hose 6; the bottom end of the liquid inlet vertical pipe 42 is connected with a liquid inlet main pipe 41, and the end of the liquid inlet main pipe 41 away from the liquid inlet vertical pipe 42 is connected with a liquid cooling inlet pipe 4; the bottom end of the liquid outlet vertical pipe 52 is connected with a liquid outlet main pipe 51, and the end of the liquid outlet main pipe 51 away from the liquid outlet vertical pipe 52 is connected with a liquid cooling outlet pipe 5; the liquid cooling inlet pipe 4 and the liquid cooling outlet pipe 5 are arranged in parallel, and are both arranged perpendicular to the truss 2;

[0042] The liquid inlet vertical pipe 42 and the liquid outlet vertical pipe 52 are used for the liquid cooling and liquid supply needs of multiple battery racks 3 in the vertical direction;

[0043] The liquid inlet pipe 41 and the liquid outlet pipe 51 are used for the liquid cooling and liquid supply needs of the two groups of battery racks 3 in the length extension direction of the truss 2;

[0044] When at least three groups of columns 1 are provided, the liquid cooling inlet pipe 4 and the liquid cooling outlet pipe 5 are used for the liquid cooling supply demand of multiple groups of battery racks 3 in the length extension direction of the liquid cooling inlet pipe 4;

[0045] Thus, a complete three-dimensional box-type liquid cooling supply structure is formed; and the three-dimensional box-type liquid cooling supply structure is self-supported by the pipeline and does not come into contact with the column 1 and the truss 2;

[0046] At the same time, the liquid-cooling supply structure does not produce a directly installed connection structure with the truss 2 and the column 1, and only a hose 6 for liquid communication is connected between the liquid-cooling supply structure and the battery frame 3, so that the additional vibration and noise generated by the liquid-cooling supply structure during operation are difficult to directly affect the normal use of the truss 2 and the column 1, and also reduce the interference with the normal operation of the battery frame 3.

[0047] Specifically, Figure 1 As shown, each group of columns 1 is provided with three columns 1, and partition bars 23 are provided at the joints between the truss 2 and the column 1 in the middle of the three columns 1. Specifically, when each group of columns 1 is provided with three columns 1, two battery racks 3 in opposite directions are simultaneously installed along the length extension direction of the truss 2, and at this time, the partition bar 23 is used to separate the two battery racks 3 in opposite directions.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
