Description

Technical Field

[0001] This utility model relates to the technical field of battery cold plate testing equipment, and in particular to an installation structure of a heating block in a battery cold plate performance testing device. Background Technology

[0002] Battery cooling plates are key components in the thermal management system of new energy vehicle batteries. Their main function is to reduce the heat generated by the battery pack during operation through coolant circulation, ensuring the battery pack operates within a suitable temperature range, thereby improving battery performance and lifespan. Battery packs generate a significant amount of heat during operation; if this heat cannot be dissipated in time, it will lead to excessively high battery temperatures, affecting battery performance and lifespan. Therefore, the role of battery cooling plates in new energy vehicles is extremely important.

[0003] The design and manufacture of battery cooling plates require consideration of various factors, among which heat dissipation efficiency is one of the most important. Higher heat dissipation efficiency can better reduce the temperature of the battery pack, thereby improving the performance and lifespan of the battery pack.

[0004] In existing battery cold plate performance testing devices, the heating block is directly mounted on the telescopic rod of a telescopic cylinder. When testing the heat dissipation performance of the battery cold plate, the telescopic rod moves the heating block downwards to press against the surface of the battery cold plate for heating. The existing method of installing the heating block has the following problems:

[0005] (1) Since the heating block is directly installed on the telescopic rod of the telescopic cylinder, when the telescopic rod drives the heating block to move downward, it is easy to cause a rigid impact between the heating block and the battery cold plate, resulting in damage to the battery cold plate.

[0006] (2) The heating block is pressed down by the telescopic rod on the telescopic cylinder, so that the heating block is pressed tightly against the surface of the battery cold plate. The downward pressing pressure is difficult to control. Utility Model Content

[0007] The main objective of this invention is to propose an installation structure for the heating block in a battery cold plate performance testing device, aiming to solve the aforementioned technical problems.

[0008] To achieve the above objectives, this utility model proposes an installation structure for a heating block in a battery cold plate performance testing device, comprising an installation plate, a first plate, a second plate, and heating blocks; a telescopic cylinder is vertically installed on the top surface of the installation plate, with the telescopic rod of the telescopic cylinder passing downward through the installation plate; the first plate is installed at the lower end of the telescopic rod; the second plate is spaced apart and positioned directly below the first plate, and the first and second plates are connected by multiple springs; the heating blocks are spaced apart and positioned directly below the second plates, and a connecting plate is fixedly connected to the top surface of the heating blocks, with a connecting rod vertically installed on the top surface of the connecting plate; the upper end of the connecting rod passes through the second plate and is screwed with an adjusting nut, and the connecting rod slides in cooperation with the second plate; a top rod is installed at the center of the second plate.

[0009] Preferably, multiple buffers are vertically installed on the second plate, with the slide rods of the buffers facing downwards and the buffer heads of the buffers embedded in the connecting plate.

[0010] Preferably, the top rod includes a connecting rod and a disc-shaped body, the connecting rod is connected to the second plate, and the disc-shaped body is integrally formed at the lower end of the connecting rod.

[0011] Preferably, a guide post is provided inside the spring, and a first guide sleeve is provided on the first plate. The lower end of the guide post is fastened to the second plate, and the upper end of the guide post is slidably inserted into the inner hole of the first guide sleeve.

[0012] Preferably, a guide rod is vertically mounted on the first plate, and a second guide sleeve is provided on the mounting plate; the guide rod is slidably inserted into the inner hole of the second guide sleeve.

[0013] Preferably, there are two connecting rods, which are respectively installed at the top diagonal positions of the connecting plate.

[0014] Preferably, there are two springs, with the lower ends of the two springs fastened to the top diagonal positions of the second plate, and the upper ends of the two springs fastened to the first guide sleeve.

[0015] Preferably, the lower end of the connecting rod is integrally formed with a flange, and the flange is screwed to the connecting plate.

[0016] Preferably, a thermocouple is vertically inserted into the connecting plate, and the lower end of the thermocouple abuts against the top surface of the heating block.

[0017] Preferably, there are two guide rods, and the lower ends of the two guide rods are respectively fastened to the diagonal positions of the top surface of the first plate.

[0018] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0019] (1) Before use, the installation structure provided by this utility model can be loosened by first loosening the adjusting nut, and the heating block will naturally descend under the action of gravity, so that there is a gap between the top surface of the connecting plate and the bottom surface of the top rod. When it is necessary to heat the battery cold plate, the heating block can first contact the surface of the battery cold plate during the downward extension of the telescopic cylinder. When the telescopic cylinder continues to extend downward, it drives the first plate and the second plate to continue to move downward, so that the top rod abuts against the top surface of the connecting plate. The telescopic cylinder continues to extend downward, driving the first plate to continue to move downward, and then the second plate can be pressed down by the spring. The second plate presses the connecting plate and the heating block by the top rod, so that the heating block is tightly attached to the battery cold plate.

[0020] (2) The installation structure provided by this utility model, due to the sliding fit between the connecting rod and the second plate, makes the heating block form a floating structure relative to the second plate, thus avoiding rigid impact between the heating block and the battery cold plate. In addition, the first plate presses the second plate downward by a spring, and the second plate presses the connecting plate and the heating block by a top rod, so that the heating block is tightly attached to the battery cold plate. Therefore, by using the spring contraction to press the heating block, the problem of difficult control of the pressing pressure in the prior art is overcome.

[0021] (3) In this invention, by installing a buffer between the second plate and the connecting plate, a good buffering effect can be achieved, further reducing the impact on the battery cold plate. Attached Figure Description

[0031] Combination Figures 1 to 3As shown, the mounting structure of the heating block in a battery cold plate performance testing device includes a mounting plate 1, a first plate body 2, a second plate body 3, and a heating block 4. A telescopic cylinder 5 is vertically mounted on the top surface of the mounting plate 1. The telescopic cylinder 5 has a telescopic rod 5a, which passes downward through the mounting plate 1. The first plate body 2 is mounted on the lower end of the telescopic rod 5a. The second plate body 3 is spaced apart and positioned directly below the first plate body 2, and the first plate body 2 and the second plate body 3 are connected by multiple springs 6. The heating block 4 is spaced apart and positioned directly below the second plate body 3. A connecting plate 4a is fixedly connected to the top surface of the heating block 4, and a connecting rod 7 is vertically mounted on the top surface of the connecting plate 4a. The upper end of the connecting rod 7 passes through the second plate body 3 and is screwed with an adjusting nut 8. The connecting rod 7 slides with the second plate body 3. A top rod 9 is installed at the center of the second plate body 3. Before use, the heating block 4 can be lowered naturally by loosening the adjusting nut 8, which will create a gap between the top surface of the connecting plate 4a and the bottom surface of the push rod 9.

[0032] Combination Figure 4 The diagram shows the heating block mounting structure assembled after the battery cold plate performance testing device. In use, the mounting plate 1 is installed on top of the support 200 of the performance testing device. When the battery cold plate 100 needs to be heated, it is placed on the sliding support plate of the performance testing device and slides into the support 200 along with the sliding support plate. During the downward extension of the telescopic rod 5a of the telescopic cylinder 5, the heating block 4 can first contact the surface of the battery cold plate 100. As the telescopic rod 5a of the telescopic cylinder 5 continues to extend downward, it drives the first plate 2 and the second plate 3 to continue moving downward, causing the top rod 9 to abut against the top surface of the connecting plate 4a. The telescopic rod 5a of the telescopic cylinder 5 continues to extend downward, driving the first plate 2 to continue moving downward, which in turn presses the second plate 3 downward through the spring 6. The second plate 3 presses the connecting plate 4a and the heating block 4 together through the top rod 9, causing the heating block 5 to adhere tightly to the battery cold plate 100.

The connecting rod 9a is connected to the second plate 3, and the disc-shaped body 9b is integrally formed at the lower end of the connecting rod 9a. The purpose of providing the disc-shaped body 9b is to increase the contact area with the connecting plate 4a and improve the clamping effect of the push rod 9 on the connecting plate 4a.

[0035] Combination Figure 2 As shown, a guide post 11 is provided inside the spring 6, and a first guide sleeve 12 is provided on the first plate 2. The lower end of the guide post 11 is fastened to the second plate 3, and the upper end of the guide post 11 is slidably inserted into the inner hole of the first guide sleeve 12. By utilizing the cooperation between the guide post 11 and the first guide sleeve 12, a guiding function is provided, improving the reliability of the movement of the first plate 2 and the second plate 3 towards or away from each other.

[0036] Combination Figure 1 , Figure 2 As shown, a guide rod 13 is vertically mounted on the first plate 2, and a second guide sleeve 14 is provided on the mounting plate 1; the guide rod 13 is slidably inserted into the inner hole of the second guide sleeve 14. The structure of the guide rod 13 cooperating with the second guide sleeve 14 plays a guiding role, ensuring that the first plate 2 moves in the vertical direction.

[0037] Combination Figure 2 As shown, there are two connecting rods 7, each installed at a diagonal position on the top surface of the connecting plate 4a. There are also two springs 6, with their lower ends fastened to the diagonal positions on the top surface of the second plate 3, and their upper ends fastened to the first guide sleeve 12. There are also two guide rods 13, with their lower ends fastened to the diagonal positions on the top surface of the first plate 2. Furthermore, the lower end of each connecting rod 7 is integrally formed with a flange 7a, which is screwed to the connecting plate 4a.
