Description

Technical Field

[0001] The present invention relates to the technical field of cooling equipment, and particularly to a cooling device. Background Art

[0002] Before injecting liquid into a battery, the battery needs to be baked to reduce the moisture content inside the battery and ensure the production quality of the battery. However, after the baking process, the temperature of the battery is relatively high. At this time, if the battery directly enters the liquid injection process, the electrolyte will decompose due to the high temperature, which will lead to a reduction in the battery life. Therefore, after baking, the battery needs to be cooled first and then enter the liquid injection process to complete the injection of the electrolyte to ensure the production quality of the battery. In related technologies, usually, the battery is passed through a fixed air duct, and the battery is cooled by air cooling. By using this method to cool the battery, since the heat exchange area between the battery and the cooling air in the air duct is relatively small, the cooling speed of the battery is relatively slow.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0033] In the description of the present application, it should be noted that, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense.

Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0035] In the embodiments of the application, "parallel" means the state where the angle formed by a straight line and a straight line, a straight line and a plane, or a plane and a plane is -1° to 1°. Additionally, "perpendicular" means the state where the angle formed by a straight line and a straight line, a straight line and a plane, or a plane and a plane is 89° to 91°. Equal distance, equal angle, or equal area means the state where the tolerance range is -1% to 1%.

[0036] As Figures 1 to 6 shown, a cooling device in a preferred embodiment of the present invention is used to cool 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 in pairs. 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 the conveyor belt 12 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 an air-cooling channel 200 for the battery 100 to enter is formed between the cooling mechanism 2 and the conveyor belt 12. 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 member 31 and a second heat-conducting member 32. The first heat-conducting member 31 and the second heat-conducting member 32 are arranged at intervals along the first direction X. The first heat-conducting member 31 and the second heat-conducting member 32 are used to clamp the battery 100, and the first heat-conducting member 31, the second heat-conducting member 32 move synchronously with the conveyor belt 12.

[0037] Specifically, the cooling mechanism 2 is used to output cooling air to the air-cooling channel 200, and the conveyor belt 12 enables the battery 100 to pass through the air-cooling channel 200 during the process of conveying the battery 100. Thus, the temperature of the battery 100 can be reduced by heat exchange between the cooling air and the battery 100. The clamping mechanism 3 is provided on the conveyor belt 12, and the clamping mechanism 3 clamps the battery 100 through the first heat-conducting member 31 and the second heat-conducting member 32, and the first heat-conducting member 31 and the second heat-conducting member 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 member 31 and the second heat-conducting member 32. When the battery 100 passes through the air-cooling channel 200, the first heat-conducting member 31 and the second heat-conducting member 32 will also exchange heat with the cooling air. That is, the setting of the clamping mechanism 3 increases the heat-exchange area between the battery 100 and the cooling air. When using this cooling device to cool the battery 100, the temperature reduction speed of the battery 100 is relatively fast, improving the heat-exchange efficiency.

[0038] Exemplarily, as Figure 2 shown, both the first heat-conducting member 31 and the second heat-conducting member 32 are multi-sheet heat sinks. The areas of the first heat-conducting member 31 and the second heat-conducting sheet in contact with the air are relatively large, and the speed at which the two transfer heat to the cooling air is relatively fast, enabling the heat to be dissipated quickly. The temperature reduction speed of the battery 100 is relatively fast, which is beneficial to improving the heat-exchange efficiency.

[0039] As Figure 2As shown in the figure, the cooling device further includes a first driving component 4. In the first direction X, the first driving component 4 is provided on both the side of the first heat conducting member 31 away from the second heat conducting member 32 and the side of the second heat conducting member 32 away from the first heat conducting member 31. The first driving component 4 includes a fixed seat 41 and an elastic component 42. The fixed seat 41 is fixedly connected to the conveyor belt 12, and the elastic component 42 is connected to the fixed seat 41 and can elastically expand and contract along the first direction X. Among them, the first heat conducting member 31 is connected to the elastic component 42 adjacent to the first driving component 4, and the second heat conducting member 32 is connected to the elastic component 42 adjacent to the first driving component 4. The first heat conducting member 31 and the second heat conducting member 32 are driven by the fixed seat 41 to move synchronously with the conveyor belt 12. Specifically, when the elastic component 42 is in the initial state, the distance between the first heat conducting member 31 and the second heat conducting member 32 is less than the length dimension of the battery 100 in the first direction X. When the battery 100 is placed between the first heat conducting member 31 and the second heat conducting member 32, the battery 100 will push open the first heat conducting member 31 and the second heat conducting member 32. At this time, the elastic component 42 is in a compressed state under the action of the force exerted by the battery 100 on the first heat conducting member 31 and the second heat conducting member 32, and the elastic force of the elastic component 42 acts on the first heat conducting member 31 and the second heat conducting member 32. Thus, the first heat conducting member 31 and the second heat conducting member 32 can clamp the battery 100, enabling the battery 100 to stably move synchronously with the conveyor belt 12. In addition, during the movement of the conveyor belt 12, since the first heat conducting member 31 and the second heat conducting member 32 clamp the battery 100, and the first heat conducting member 31 and the second heat conducting member 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 member 31 and the second heat conducting member 32, and the outer surface of the battery 100 can be prevented from being scratched by the first heat conducting member 31 and the second heat conducting member 32.

[0040] As Figure 5 shown, in the third direction Z, there are gaps 300 between the first heat conducting member 31 and the conveyor belt 12 and between the second heat conducting member 32 and the conveyor belt 12. Thus, during the process of the first heat conducting member 31 and the second heat conducting member 32 being pushed open by the battery 100 and during the process of moving along the first direction X driven by the elastic component 42, there is no relative friction with the conveyor belt 12, and wear of the conveyor belt 12 can be avoided.

[0041] Further, as Figure 1 and Figure 2As shown, the number of clamping mechanisms 3 is multiple, and the multiple clamping mechanisms 3 are arranged at intervals along the first direction X. Along the first direction X, among 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. Among them, the second heat conducting member 32 of the first clamping mechanism 3A and the first heat conducting member 31 of the second clamping mechanism 3B are connected to the elastic component 42 of the same first driving member 4. That is, there is no need to set two first driving members 4 between two adjacent clamping mechanisms 3. Therefore, there is no need to reserve space for the two first driving members 4, making the spatial layout between adjacent clamping mechanisms 3 more compact, and the cooling device has the characteristic of a compact structure.

[0042] As Figure 5 shown, among the first driving members 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 clamped to the fixed seat 41 at intervals 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 member 32 of the first clamping mechanism 3A, and the second slider 422 is fixedly connected to the first heat conducting member 31 of the second clamping mechanism 3B. Since the fixed seat 41 is fixedly connected to the conveyor belt 12, therefore, through the first slider 421, the second slider 422, and the fixed seat 41, the first heat conducting member 31 and the second heat conducting member 32 can move synchronously with the conveyor belt 12. The spring 423 is arranged between the first slider 421 and the second slider 422. The length direction of the spring 423 extends along the first direction X, and both 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 is used to provide an elastic force to clamp the battery 100 by the first heat conducting member 31 and the second heat conducting member 32, with a simple structure and low cost.

[0043] In this embodiment, as Figure 1 and Figure 5 shown, the conveyor belt 12 moves in a circular track in a cycle. The conveying mechanism 1 further includes a guide rail 13. The guide rail 13 is circular, and the guide rail 13 surrounds the outer peripheral side of the conveyor belt 12. The fixed seat 41 is slidably connected to the guide rail 13. The setting of the slide rail plays a guiding role to ensure that the fixed seat 41 moves synchronously with the conveyor belt 12 along the correct movement track.

[0044] Furthermore, as Figure 1As shown, the cooling device further includes a second driving member 5. The second driving member 5 is connected to one end of the frame 11 in the second direction Y. The second driving member 5 is used to drive the first heat conducting member 31 and the second heat conducting member 32 in the clamping mechanism 3 to move relatively away from each other in the first direction X, so as to increase the distance between the first heat conducting member 31 and the second heat conducting member 32 in the first direction X. In practical applications, the end of the frame 11 where the second driving member 5 is provided is the input end of the battery 100. When it is necessary to cool the battery 100, the second driving member 5 drives the first heat conducting member 31 and the second heat conducting member 32 to move away from each other, so as to reserve enough space between the first heat conducting member 31 and the second heat conducting member 32 for the battery 100 to be placed therebetween. After the battery 100 is placed between the first heat conducting member 31 and the second heat conducting member 32, the elastic force of the spring 423 causes the first heat conducting member 31 and the second heat conducting member 32 to clamp the battery 100.

[0045] As Figure 2As shown, the cooling device further includes a first connecting block 6. In the third direction Z, on the side of the first heat conducting member 31 facing away from the conveyor belt 12, a first connecting block 6 is connected. On the side of the first connecting block 6 facing away from the conveyor belt 12, a first positioning hole 601 is provided; the second driving member 5 includes a mounting seat 51, a driving assembly 52, a first connecting rod 53, a first driving member 54, and a first positioning post 55. The mounting seat 51 is connected to the frame 11, and the driving assembly 52 is connected to the mounting seat 51; the first connecting rod 53 is connected to the driving assembly 52, and the driving assembly 52 is used to drive the first connecting rod 53 to move in the first direction X away from the corresponding second heat conducting member 32. The number of the first driving members 54 and the first positioning posts 55 is multiple. The multiple first driving members 54 are spaced and connected to the first connecting rod 53 in the first direction X, and each first driving member 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 member 54 is used to drive the first positioning post 55 to move in the third direction Z, and the first positioning post 55 is used to insert into the first positioning hole 601. In practical applications, in the initial state of the clamping mechanism 3, no battery 100 is provided between the first heat conducting member 31 and the second heat conducting member 32. At this time, in the third direction Z, each first connecting block 6 on the first heat conducting member 31 faces a first positioning post 55. When it is necessary to cool the battery 100, the first driving member 54 drives the first positioning post 55 connected thereto to move in 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. Thereafter, the driving assembly 52 drives the first connecting rod 53 to move in the first direction X away from the corresponding second heat conducting member 32, thereby causing the first heat conducting member 31 to move relative to the second heat conducting member 32, so as to reserve enough space between the first heat conducting member 31 and the second heat conducting member 32 for placing the battery 100. The second driving member 5 with such a structure can make the first heat conducting members 31 in all the clamping mechanisms 3 move relative to the corresponding second heat conducting members 32, so that all the clamping mechanisms 3 can reserve enough space simultaneously, facilitating the placement of the battery 100; after a battery 100 is placed in each clamping mechanism 3, the first driving member 54 drives the first positioning post 55 to move away from the first connecting block 6 in the third direction Z, and the driving assembly 52 drives the first connecting rod 53 to reset. At this time, the first heat conducting member 31 resets under the action of the spring 423 connected thereto, and the first heat conducting member 31 cooperates with the second heat conducting member 32 to clamp the corresponding battery 100.

[0046] Further, as Figure 2As shown, the cooling device further includes a second connection block 7. In the third direction Z, on the side of the second heat conducting member 32 facing away from the conveyor belt 12, a second connection block 7 is connected. On the side of the second connection block 7 facing away from the conveyor belt 12, a second positioning hole 701 is provided; the second driving member 5 further includes a second connecting rod 56, a second driving member 57, and a second positioning post 58; the second connecting rod 56 is connected to the driving assembly 52, and the driving assembly 52 is configured to drive the second connecting rod 56 to move in the first direction X away from the corresponding first heat conducting member 31. The number of the second driving members 57 and the second positioning posts 58 is multiple. The multiple second driving members 57 are spaced and connected to the second connecting rod 56 in the first direction X, and 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 configured to drive the second positioning post 58 to move in the third direction Z, and the second positioning post 58 is configured to be inserted into the second positioning hole 701. Similarly, in the initial state, in the third direction Z, each second heat conducting member 32 has a second connection block 7 facing a second positioning post 58. When it is necessary to cool the battery 100, the second driving member 57 drives the second positioning post 58 connected thereto to move in the third direction Z toward the corresponding second connection block 7, so that the second positioning post 58 is inserted into the second positioning hole 701 on the corresponding second connection block 7. Thereafter, the driving assembly 52 drives the second connecting rod 56 to move in the first direction X away from the corresponding first heat conducting member 31, thereby causing the second heat conducting member 32 to move away from the first heat conducting member 31, so as to reserve enough space between the first heat conducting member 31 and the second heat conducting member 32 for placing the battery 100. The second driving member 5 with such a structure can make the first heat conducting members 31 and the second heat conducting members 32 in all the clamping mechanisms 3 move away from each other simultaneously. Its advantage is that it can quickly separate the first heat conducting member 31 and the second heat conducting member 32 to a preset distance for placing the battery 100, and the first heat conducting member 31 and the second heat conducting member 32 only need a relatively short stroke to reserve enough space. The cooling device does not need to reserve too much space for the movement of the first heat conducting member 31 and the second heat conducting member 32, and the structure of the cooling device is more compact.

[0047] After each clamping mechanism 3 is placed with a battery 100, similarly, the second driving member 57 drives the second positioning post 58 to move away from the second connection block 7 in the third direction Z, and the driving assembly 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 thereto, and the second heat conducting member 32 cooperates with the first heat conducting member 31 to clamp the corresponding battery 100.

[0048] Exemplarily, the above-mentioned first driving member 54 and second driving member 57 are both cylinders; in other embodiments, the first driving member 54 and second driving member 57 can also be electric cylinders or driving components well-known to those skilled in the art that can drive an object to move in a straight line, and the present application does not limit this.

[0049] As Figure 3 and Figure 4 shown, the driving assembly 52 includes a first connecting member 521, a second connecting member 522, a cam 523 and a third driving member 524. The first connecting member 521 is connected to the first connecting rod 53, the second connecting member 522 is connected to the second connecting rod 56, and the first connecting member 521 and the second connecting member 522 are arranged at intervals along the first direction X. The cam 523 is disposed between the first connecting member 521 and the second connecting member 522. The axis of the cam 523 extends along the second direction Y. The circumferential surface of the cam 523 is in contact with the first connecting member 521 and the second connecting member 522. The cam 523 is connected to the third driving member 524. The third driving member 524 is connected to the mounting seat 51, and the third driving member 524 is used to drive the cam 523 to rotate around its axis. Among them, the circumferential surface of the cam 523 refers to the side surface around its axis direction, and the third driving member 524 is a motor. In practical applications, when it is necessary to place the battery 100 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. This driving assembly 52 that realizes the mutual separation of the first connecting rod 53 and the second connecting rod 56 through the cam 523 has the advantage that by reasonably planning the shape of the cam 523 and reasonably controlling the movement of the cam 523, the displacement amount of the mutual separation of the first connecting rod 53 and the second connecting rod 56 can be accurately controlled, so that the first heat conducting member 31 and the second heat conducting member 32 can have an accurate stroke when moving along the first direction X, and the reliability is high.

[0050] In addition, to realize the mutual separation of the first connecting rod 53 and the second connecting rod 56 through the driving assembly 52 with the above structure, after the battery 100 is placed, first, the third driving member 524 drives the cam 523 to reset. At this time, during the process that the spring 423 drives the first heat conducting member 31 and the second heat conducting member 32 to reset to clamp the battery 100, the first heat conducting member 31 and the second heat conducting member 32 will also drive the first connecting rod 53 and the second connecting rod 56 to move and reset, so that the first connecting member 521 and the second connecting member 522 are reset to the position in contact with the circumferential surface of the cam 523. After that, the first driving member 54 drives the first positioning post 55 away from the first connecting block 6, and the second driving member 57 drives the second positioning post 58 away from the second connecting block 7.

[0051] Further, the second driving member 5 further includes a guide rod 59. The guide rod 59 is connected to the mounting base 51, and the length direction of the guide rod 59 extends along the first direction X. 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. The number of the first rod bodies 531 is multiple, and the multiple first rod bodies 531 are spaced and connected to the second rod body 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 the first connecting member 521 is fixedly connected to the second rod body 532. Wherein, the first rod body 531 has a first guiding hole 5310 penetrating along the first direction X, and the guide rod 59 passes through all the first guiding 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. The number of the third rod bodies 561 is multiple, and the multiple third rod bodies 561 are spaced 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, and the second connecting member 522 is fixedly connected to the fourth rod body 562. Wherein, the third rod body 561 has a second guiding hole 5610 penetrating along the first direction X, and the guide rod 59 passes through all the second guiding holes 5610. Specifically, the arrangement of the guide rod 59 can provide precise movement guidance for the first connecting rod 53 and the second connecting rod 56, ensure their movement along the first direction X, and has high reliability.

[0052] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
