Description

Technical Field

[0001] This invention relates to the field of cooling equipment technology, and in particular to a cooling device. Background Technology

[0002] Before electrolyte filling, batteries need to be baked to reduce internal moisture content and ensure production quality. However, after baking, the battery temperature is relatively high. If the battery directly enters the electrolyte filling process at this temperature, the electrolyte will decompose due to the high temperature, which will reduce battery life. Therefore, after baking, the battery needs to be cooled down before entering the electrolyte filling process to ensure production quality. In related technologies, the battery is usually cooled by passing it through a fixed air duct. However, this method results in a relatively slow cooling rate because the heat exchange area between the battery and the cooling air in the air duct is relatively small. Summary of the Invention

[0022] The cooling device of this invention has the following advantages compared with the prior art:

[0023] The cooling device of the present invention includes a cooling mechanism for outputting cooling air to the air-cooling channel. During battery transport, the conveyor belt carries the battery through the air-cooling channel, thereby achieving battery cooling through heat exchange between the cooling air and the battery. The conveyor belt is equipped with a clamping mechanism that clamps the battery using a first heat-conducting element and a second heat-conducting element. The first and second heat-conducting elements move synchronously with the conveyor belt, thus transferring heat from the battery to the first and second heat-conducting elements. As the battery passes through the air-cooling channel, the first and second heat-conducting elements also exchange heat with the cooling air. In other words, the clamping mechanism increases the heat exchange area between the battery and the cooling air. Using this cooling device, the battery cools down relatively quickly, improving heat exchange efficiency. Attached Figure Description

[0036] like Figures 1 to 6 As shown, a preferred embodiment of the present invention provides a cooling device for cooling a battery 100. The cooling device has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other. The cooling device includes a conveying mechanism 1, a cooling mechanism 2, and a clamping mechanism 3. The conveying mechanism 1 includes a frame 11 and a conveyor belt 12. The conveyor belt 12 is connected to the frame 11 and is used to convey the battery 100 along the second direction Y. The cooling mechanism 2 is connected to the frame 11 along the third direction Z, and a battery supply is formed between the cooling mechanism 2 and the conveyor belt 12. The battery 100 enters the air-cooling channel 200. The cooling mechanism 2 is used to output cooling air to the air-cooling channel 200 so that the battery 100 is cooled in the air-cooling channel 200. The clamping mechanism 3 is arranged on the conveyor belt 12 along the third direction Z. The clamping mechanism 3 includes a first heat-conducting element 31 and a second heat-conducting element 32. The first heat-conducting element 31 and the second heat-conducting element 32 are arranged at intervals along the first direction X. The first heat-conducting element 31 and the second heat-conducting element 32 are used to clamp the battery 100. The first heat-conducting element 31 and the second heat-conducting element 32 move synchronously with the conveyor belt 12.

[0037] Specifically, the cooling mechanism 2 outputs cooling air to the air-cooling channel 200. During the process of transporting the battery 100, the conveyor belt 12 causes the battery 100 to pass through the air-cooling channel 200. Thus, the battery 100 can be cooled down by exchanging heat with the cooling air. The conveyor belt 12 is equipped with a clamping mechanism 3, which clamps the battery 100 through a first heat-conducting element 31 and a second heat-conducting element 32. The first heat-conducting element 31 and the second heat-conducting element 32 move synchronously with the conveyor belt 12. Based on this, the heat on the battery 100 will be transferred to the first heat-conducting element 31 and the second heat-conducting element 32. When the battery 100 passes through the air-cooling channel 200, the first heat-conducting element 31 and the second heat-conducting element 32 will also exchange heat with the cooling air. That is, the clamping mechanism 3 increases the heat exchange area between the battery 100 and the cooling air. Using this cooling device to cool the battery 100 results in a faster cooling rate for the battery 100 and improves the heat exchange efficiency.

[0038] For example, such as Figure 2 As shown, the first heat-conducting element 31 and the second heat-conducting element 32 are both multi-plate heat sinks. The first heat-conducting element 31 and the second heat-conducting element have a relatively large contact area with the air, and the two can transfer heat to the cooling air at a relatively fast speed, which can quickly dissipate the heat and make the battery 100 cool down quickly, which is beneficial to improving the heat exchange efficiency.

[0039] like Figure 2As shown, the cooling device also includes a first driving component 4. In the first direction X, the first driving component 4 is provided on the side of the first heat-conducting element 31 away from the second heat-conducting element 32 and on the side of the second heat-conducting element 32 away from the first heat-conducting element 31. The first driving component 4 includes a fixed base 41 and an elastic component 42. The fixed base 41 is fixedly connected to the conveyor belt 12, and the elastic component 42 is connected to the fixed base 41. The elastic component 42 can elastically extend and retract along the first direction X. The first heat-conducting element 31 is connected to the elastic component 42 adjacent to the first driving component 4, and the second heat-conducting element 32 is connected to the elastic component 42 adjacent to the first driving component 4. The first heat-conducting element 31 and the second heat-conducting element 32 are driven by the fixed base 41 to move synchronously with the conveyor belt 12. Specifically, in the initial state, the distance between the first heat-conducting element 31 and the second heat-conducting element 32 is less than the length of the battery 100 in the first direction X. When the battery 100 is placed between the first heat-conducting element 31 and the second heat-conducting element 32, the battery 100 will spread the first heat-conducting element 31 and the second heat-conducting element 32 apart. At this time, the elastic component 42 is compressed by the force exerted by the battery 100 on the first heat-conducting element 31 and the second heat-conducting element 32, and the elastic force of the elastic component 42 acts on the first heat-conducting element 31 and the second heat-conducting element 32. Thus, the first heat-conducting element 31 and the second heat-conducting element 32 can clamp the battery 100, so that the battery 100 moves synchronously with the conveyor belt 12 stably. In addition, during the movement of the conveyor belt 12, since the first heat-conducting element 31 and the second heat-conducting element 32 clamp the battery 100 and the first heat-conducting element 31 and the second heat-conducting element 32 are driven by the fixed seat 41 to move synchronously with the conveyor belt 12, there is no relative friction between the battery 100 and the first heat-conducting element 31 and the second heat-conducting element 32, which can prevent the outer surface of the battery 100 from being scratched by the first heat-conducting element 31 and the second heat-conducting element 32.

[0040] like Figure 5 As shown, in the third direction Z, there is a gap 300 between the first heat-conducting component 31 and the conveyor belt 12, and between the second heat-conducting component 32 and the conveyor belt 12. Therefore, the first heat-conducting component 31 and the second heat-conducting component 32 will not rub against the conveyor belt 12 during the process of being spread open by the battery 100 and during the process of moving along the first direction X under the drive of the elastic component 42, so as to avoid wear on the conveyor belt 12.

[0041] Furthermore, such as Figure 1 and Figure 2As shown, there are multiple clamping mechanisms 3, which are arranged at intervals along the first direction X. Along the first direction X, in two adjacent clamping mechanisms 3, one clamping mechanism 3 is the first clamping mechanism 3A and the other clamping mechanism 3 is the second clamping mechanism 3B. The second heat-conducting component 32 of the first clamping mechanism 3A and the first heat-conducting component 31 of the second clamping mechanism 3B are connected to the elastic component 42 of the same first driving component 4. That is, there is no need to set two first driving components 4 between two adjacent clamping mechanisms 3. Therefore, there is no need to reserve space for two first driving components 4, making the spatial layout between adjacent clamping mechanisms 3 more compact. The cooling device has the characteristics of a compact structure.

[0042] like Figure 5 As shown, in the first driving component 4 between two adjacent clamping mechanisms 3, the elastic component 42 includes a first slider 421, a second slider 422, and a spring 423. The first slider 421 and the second slider 422 are spaced apart and engaged with the fixed base 41 along the first direction X, and the first slider 421 and the second slider 422 can slide along the first direction X. The first slider 421 is fixedly connected to the second heat-conducting element 32 of the first clamping mechanism 3A, and the second slider 422 is fixedly connected to the first heat-conducting element 31 of the second clamping mechanism 3B. Since the fixed base 41 is fixedly connected to the conveyor belt... Therefore, through the first slider 421, the second slider 422 and the fixed seat 41, the first heat-conducting element 31 and the second heat-conducting element 32 can move synchronously with the conveyor belt 12; while the spring 423 is disposed between the first slider 421 and the second slider 422. The length direction of the spring 423 extends along the first direction X, and the two ends of the spring 423 along its length direction are respectively connected to the first slider 421 and the second slider 422. The spring 423 provides elastic force to clamp the first heat-conducting element 31 and the second heat-conducting element 32 to the battery 100. The structure is simple and the cost is low.

[0043] In this embodiment, as Figure 1 and Figure 5 As shown, the conveyor belt 12 moves cyclically along a circular track. The conveying mechanism 1 also includes a guide rail 13, which is circular and surrounds the outer periphery of the conveyor belt 12. The fixed seat 41 is slidably connected to the guide rail 13. The guide rail serves as a guide to ensure that the fixed seat 41 moves synchronously with the conveyor belt 12 along the correct movement trajectory.

[0044] Furthermore, such as Figure 1As shown, the cooling device also includes a second driving component 5, which is connected to one end of the frame 11 in the second direction Y. The second driving component 5 is used to drive the first heat-conducting element 31 and the second heat-conducting element 32 in the clamping mechanism 3 to move relative to each other in the first direction X, so as to increase the distance between the first heat-conducting element 31 and the second heat-conducting element 32 in the first direction X. In practical applications, the end of the frame 11 with the second driving component 5 is the input end of the battery 100. When it is necessary to cool the battery 100, the second driving component 5 drives the first heat-conducting element 31 and the second heat-conducting element 32 to move away from each other, so as to leave enough space between the first heat-conducting element 31 and the second heat-conducting element 32, so that the battery 100 can be placed between the first heat-conducting element 31 and the second heat-conducting element 32. After the battery 100 is placed between the first heat-conducting element 31 and the second heat-conducting element 32, the elastic force of the spring 423 clamps the battery 100 between the first heat-conducting element 31 and the second heat-conducting element 32.

[0045] like Figure 2As shown, the cooling device also includes a first connecting block 6. On the third direction Z, the side of the first heat-conducting element 31 facing away from the conveyor belt 12 is connected to the first connecting block 6. The side of the first connecting block 6 facing away from the conveyor belt 12 is provided with a first positioning hole 601. The second driving component 5 includes a mounting base 51, a driving assembly 52, a first connecting rod 53, a first driving component 54, and a first positioning post 55. The mounting base 51 is connected to the frame 11, and the driving assembly 52 is connected to the mounting base 51. The first connecting rod 53 is connected to the driving assembly 52, and the driving assembly 52 uses… The first driving link 53 is driven to move along the first direction X in a direction away from the corresponding second heat-conducting component 32. There are multiple first driving components 54 and multiple first positioning posts 55. Multiple first driving components 54 are connected to the first link 53 at intervals along the first direction X, and each first driving component 54 is connected to a first positioning post 55. The length direction of the first positioning post 55 extends along the third direction Z. The first driving component 54 is used to drive the first positioning post 55 to move in the third direction Z. The first positioning post 55 is used to insert into the first positioning hole 601. In practical applications, in the initial state, the clamping mechanism 3 does not have a battery 100 between the first heat-conducting element 31 and the second heat-conducting element 32. At this time, in the third direction Z, the first connecting block 6 on each first heat-conducting element 31 is directly opposite a first positioning post 55. When cooling of the battery 100 is required, the first driving member 54 drives the first positioning post 55 connected to it to move along the third direction Z toward the corresponding first connecting block 6, so that the first positioning post 55 is inserted into the first positioning hole 601 on the corresponding first connecting block 6. Afterward, the driving assembly 52 drives the first connecting rod 53 to move along the first direction X toward the direction away from the corresponding second heat-conducting element 32, thereby causing the first heat-conducting element 31 to move relative to the second heat-conducting element 32. Sufficient space is reserved between the first heat-conducting element 31 and the second heat-conducting element 32 for placing the battery 100. The second driving component 5 with this structure can move the first heat-conducting element 31 in all clamping mechanisms 3 relative to the corresponding second heat-conducting element 32, so that all clamping mechanisms 3 can simultaneously reserve sufficient space for placing the battery 100. After the battery 100 is placed in each clamping mechanism 3, the first driving component 54 drives the first positioning post 55 to move away from the first connecting block 6 in the third direction Z. The driving component 52 drives the first connecting rod 53 to reset. At this time, the first heat-conducting element 31 is reset under the action of the spring 423 connected to it. The first heat-conducting element 31 cooperates with the second heat-conducting element 32 to clamp the corresponding battery 100.

[0046] Furthermore, such as Figure 2As shown, the cooling device also includes a second connecting block 7. On the third direction Z, the side of the second heat-conducting element 32 facing away from the conveyor belt 12 is connected to the second connecting block 7. The side of the second connecting block 7 facing away from the conveyor belt 12 is provided with a second positioning hole 701. The second driving component 5 also includes a second connecting rod 56, a second driving element 57, and a second positioning post 58. The second connecting rod 56 is connected to the driving assembly 52, which drives the second connecting rod 56 to move along the first direction X in a direction away from the corresponding first heat-conducting element 31. The second driving element 57 and the second positioning post... There are multiple second driving members 57, which are spaced apart along the first direction X and connected to the second connecting rod 56. Each second driving member 57 is connected to a second positioning post 58. The length direction of the second positioning post 58 extends along the third direction Z. The second driving member 57 is used to drive the second positioning post 58 to move in the third direction Z. The second positioning post 58 is used to insert into the second positioning hole 701. Similarly, in the initial state, in the third direction Z, the second connecting block 7 on each second heat conducting member 32 is directly opposite a second positioning post 58. 8. When cooling of the battery 100 is required, the second driving member 57 drives the second positioning post 58 connected to it to move along the third direction Z toward the corresponding second connecting block 7, so that the second positioning post 58 is inserted into the second positioning hole 701 on the corresponding second connecting block 7. Afterwards, the driving assembly 52 drives the second connecting rod 56 to move along the first direction X toward the direction away from the corresponding first heat conductor 31, thereby moving the second heat conductor 32 away from the first heat conductor 31, so that sufficient space is reserved between the first heat conductor 31 and the second heat conductor 32. For placing the battery 100, the second drive component 5 of this structure enables the first heat-conducting element 31 and the second heat-conducting element 32 in all clamping mechanisms 3 to move in opposite directions simultaneously. Its advantage is that it can quickly separate the first heat-conducting element 31 and the second heat-conducting element 32 to a preset distance for placing the battery 100. Moreover, the first heat-conducting element 31 and the second heat-conducting element 32 only need a relatively short stroke to reserve sufficient space. The cooling device does not need to reserve too much space for the first heat-conducting element 31 and the second heat-conducting element 32 to move, and the structure of the cooling device is more compact.

[0047] After each clamping mechanism 3 has a battery 100 placed in it, the second driving member 57 drives the second positioning post 58 to move away from the second connecting block 7 in the third direction Z. The driving component 52 drives the second connecting rod 56 to reset. At this time, the second heat-conducting member 32 is reset under the action of the spring 423 connected to it. The second heat-conducting member 32 cooperates with the first heat-conducting member 31 to clamp the corresponding battery 100.

[0048] For example, the first driving component 54 and the second driving component 57 described above are both cylinders; in other embodiments, the first driving component 54 and the second driving component 57 may also be electric cylinders or driving components known to those skilled in the art that can drive an object to perform linear motion, and this application does not limit them.

[0049] like Figure 3 and Figure 4 As shown, the drive assembly 52 includes a first connector 521, a second connector 522, a cam 523, and a third drive member 524. The first connector 521 is connected to the first connecting rod 53, and the second connector 522 is connected to the second connecting rod 56. The first connector 521 and the second connector 522 are spaced apart along the first direction X. The cam 523 is located between the first connector 521 and the second connector 522. The axis of the cam 523 extends along the second direction Y. The peripheral side of the cam 523 contacts the first connector 521 and the second connector 522. The cam 523 is connected to the third drive member 524, which is connected to the mounting base 51. The third drive member 524 is used to drive the cam 523 to rotate around its axis. The peripheral side of the cam 523 refers to the side around its axis. The third drive member 524 is a motor. In practical applications, when the battery 100 needs to be placed in the clamping mechanism 3, the third driving member 524 drives the cam 523 to rotate. Under the action of the cam 523, the first connecting member 521 and the second connecting member 522 move away from each other along the first direction X, thereby driving the first connecting rod 53 and the second connecting rod 56 to move away from each other along the first direction X. The advantage of this driving component 52, which uses the cam 523 to move the first connecting rod 53 and the second connecting rod 56 away from each other, is that by rationally planning the shape of the cam 523 and rationally controlling the movement of the cam 523, the displacement of the first connecting rod 53 and the second connecting rod 56 away from each other can be precisely controlled. This allows the first heat-conducting member 31 and the second heat-conducting member 32 to have accurate strokes when moving along the first direction X, resulting in high reliability.

[0050] In addition, the drive assembly 52 of the above structure enables the first link 53 and the second link 56 to move away from each other. After the battery 100 is placed, the third drive member 524 drives the cam 523 to reset. At this time, the spring 423 drives the first heat conductor 31 and the second heat conductor 32 to reset in order to clamp the battery 100. The first heat conductor 31 and the second heat conductor 32 will also drive the first link 53 and the second link 56 to move and reset, so that the first connector 521 and the second connector 522 are reset to the position of contacting the peripheral side of the cam 523. After that, the first drive member 54 drives the first positioning post 55 away from the first connecting block 6, and the second drive member 57 drives the second positioning post 58 away from the second connecting block 7.

[0051] Furthermore, the second driving component 5 also includes a guide rod 59, which is connected to the mounting base 51. The guide rod 59 extends along the first direction X in its length direction. The first connecting rod 53 includes a first rod body 531 and a second rod body 532. The length direction of the first rod body 531 extends along the second direction Y, and the length direction of the second rod body 532 extends along the first direction X. There are multiple first rod bodies 531, which are spaced apart and connected to the second rod bodies 532 along the first direction X. Among the multiple first driving members 54, one first driving member 54 is connected to one first rod body 531, and a first connecting member 521 is fixedly connected to the second rod body 532. The first rod body 531 has a first connecting member that extends through the first direction X. Guide holes 5310 are provided, and guide rods 59 pass through all the first guide holes 5310. The second connecting rod 56 includes a third rod body 561 and a fourth rod body 562. The length direction of the third rod body 561 extends along the second direction Y, and the length direction of the fourth rod body 562 extends along the first direction X. There are multiple third rod bodies 561, which are spaced apart and connected to the fourth rod body 562 along the first direction X. Among the multiple second driving members 57, one second driving member 57 is connected to one third rod body 561. The second connecting member 522 is fixedly connected to the fourth rod body 562. The third rod body 561 has a second guide hole 5610 that extends along the first direction X, and the guide rods 59 pass through all the second guide holes 5610. Specifically, the guide rods 59 can provide precise motion guidance for the first connecting rod 53 and the second connecting rod 56, ensuring their movement along the first direction X and high reliability.

[0052] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
