Description

Technical Field

[0001] This utility model belongs to the field of battery cell transportation, and specifically relates to an integrated battery cell heat dissipation tray. Background Technology

[0002] The announcement number is CN220652094U, the subject of which is a utility model patent for a heat-dissipating large cylindrical lithium battery tray compatible with multiple diameters. Its IPC classification number is H01M10 / 44. The technical solution disclosed is that "a bushing can be detachably installed in each small rectangular area. The bushing is a rectangle adapted to the small rectangular area. Parallel first ribs are evenly distributed between opposite sides of the four sides of the bushing. The longitudinal and transverse first ribs together divide the upper surface of the bushing into a first grid. There are vertically downward extending baffles on the sides of the grid. The baffles around the grid form a battery mounting slot. Each battery mounting slot is aligned with a probe hole on the base plate."

[0003] Therefore, the above utility model patents have disclosed one technical solution for lithium battery trays. However, the technical solutions disclosed in these utility model patents focus on compatibility with cylindrical lithium batteries with diameters ranging from 32mm to 46mm, and do not further address issues such as preventing accidental cell detachment while promoting heat exchange between the cell and the external environment, which require further improvement. Utility Model Content

[0005] This utility model adopts the following technical solution: an integrated battery cell heat dissipation tray, including a base and multiple pads, wherein:

[0006] The base has a base body and a plurality of first side blocks and a plurality of second side blocks distributed along the bottom outer edge of the base body. The first side blocks and the second side blocks are integrally formed with the base body, and the bottom surface of the pad block is flush with the bottom surface of the first side block and the bottom surface of the second side block.

[0007] The base body has multiple battery cell positioning holes, which are vertically penetrating the base body.

[0008] The pad is located at the bottom of the base body and is fixedly connected to the base body;

[0009] The pad, the first side block, and the second side block only cover part of the cell positioning hole.

[0010] As a preferred technical solution of the above technical solution, the first side block is located at the corner of the bottom outer edge of the base body, and the second side block is distributed along any one of the bottom outer edges of the base body.

[0011] As a preferred technical solution to the above technical solutions, the outer surface of the battery cell is in contact with the inner wall of the battery cell positioning hole.

[0012] As a preferred technical solution of the above technical solution, the side of the base body is provided with a plurality of base protrusions and a plurality of base embedding grooves, the base protrusions and base embedding grooves are located on opposite sides of the base body, and the base protrusions are embedded in the base embedding grooves.

[0014] The integrated battery cell heat dissipation tray disclosed in this utility model has the following advantages: the integrated design of the base and pad combination structure achieves effective support and efficient heat dissipation for the battery cell. Specifically, the pad, first side block, and second side block only partially cover the battery cell positioning holes, preventing accidental detachment of the battery cell while leaving sufficient uncovered area to promote heat exchange between the battery cell and the external environment. Simultaneously, the battery cell fits tightly against the inner wall of the positioning hole, enhancing heat conduction and aiding heat dissipation. Furthermore, the protrusions and embedding grooves on the sides of the base allow multiple trays to be interlocked, forming a modular combination that facilitates expanded use.

Detailed Implementation

[0024] This utility model discloses an integrated battery cell heat dissipation tray. The following description refers to a preferred embodiment (Embodiment 1), with reference to the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0025] See attached diagram. Figures 1 to 8 , Figures 1 to 4 The integrated battery cell heat dissipation tray is shown from different perspectives. Figures 5 to 8 The partial structures of the integrated battery cell heat dissipation tray are shown respectively.

[0026] Example 1.

[0027] Preferably, the integrated battery cell heat dissipation tray includes a base 100 and multiple pads 200, wherein:

[0028] The base 100 is provided with a base body 110 and a plurality of first side blocks 120 and a plurality of second side blocks 130 distributed along the bottom outer edge of the base body 110. The first side blocks 120 and the second side blocks 130 are integrally formed with the base body 110. The bottom surface of the pad block 200 is flush with the bottom surface of the first side block 120 and the bottom surface of the second side block 130.

[0029] The base body 110 has multiple battery cell positioning holes 111, which are vertically penetrating the base body 110.

[0030] The pad 200 is located at the bottom of the base body 110 and is fixedly connected to the base body 110;

[0031] The pad 200, the first side block 120, and the second side block 130 all cover only a portion of the cell positioning hole 111. This allows the cell (not shown in the figure) to be inserted into any cell positioning hole 111 as needed. At the same time, the cell inserted into the cell positioning hole 111 is effectively supported by the pad 200 (or a combination of the pad 200 and the second side block 130, or a combination of the pad 200, the first side block 120, and the second side block 130), preventing the cell from unintendedly detaching from the cell positioning hole 111. Meanwhile, since the pad 200, the first side block 120, and the second side block 130 all cover only a portion of the cell positioning hole 111, the cell positioning hole 111 is not completely "blocked." Instead, sufficient uncovered areas remain uncovered by the pad 200, the first side block 120, and the second side block 130, allowing the cell to utilize these uncovered areas for heat exchange with the external environment, thus aiding in cell heat dissipation.

[0032] The first side block 120 is located at the corner of the bottom outer edge of the base body 110 (the connection between two adjacent sides of the bottom outer edge, usually the included angle between the two adjacent sides is a right angle), and the second side block 120 is distributed along any one side of the bottom outer edge of the base body 110.

[0033] When the battery cell is inserted into the battery cell positioning hole 111, the outer surface of the battery cell is in contact with (and tightly fitted to) the inner wall of the battery cell positioning hole 111; so that the battery cell can achieve heat conduction with the base body 110 and assist in heat dissipation of the battery cell.

[0034] The base body 110 has multiple base protrusions 112 and multiple base embedding grooves 113 on its side. The base protrusions 112 and base embedding grooves 113 are located on opposite sides of the base body 110. The base protrusions 112 are embedded in the base embedding grooves 113 (of adjacent integrated battery cell heat dissipation trays). This allows multiple integrated battery cell heat dissipation trays to fit together and form an integrated combination effect.

[0035] The bottom of the first side block 120 has a first side block groove 121, the bottom of the second side block 130 has two second side block grooves 131, and the bottom of the pad block 200 has four pad block grooves 201.

[0036] It is worth mentioning that the material and other technical features of the base 100 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement methods of these technical features can be adopted by conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0037] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
