Cold plate assemblies generally include flow plate, cover plate and other components, which need to be connected together by brazing.

[0003] When welding the manifold plate and the cover plate, a positioning structure is required to clamp the manifold plate and the cover plate together. The positioning structure of the cold plate assembly in the related art has insufficient clamping and positioning effect on the cold plate assembly, resulting in quality problems in the produced cold plate assembly.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0041] Combine the following Figures 1 to 7 The cold plate positioning tool and the cold plate positioning device of the present application are described.

[0042] According to the embodiment of the first aspect of the present application, Figure 1 and Figure 4 As shown, the cold plate positioning tooling includes a tooling base 1, a tooling cover 2 and an elastic clamping assembly 5, an installation space 3 is formed between the tooling cover 2 and the tooling base 1, the installation space 3 is used to install the cold plate assembly 4, the connecting end of the elastic clamping assembly 5 is connected to the tooling base 1 or the tooling cover 2, and the positioning end of the elastic clamping assembly 5 is used to abut the cold plate assembly 4.

[0043] According to the cold plate positioning tooling of the embodiment of the present application, when in use, the cold plate assembly 4 is placed in the installation space 3, and then the tooling cover plate 2 is moved relative to the tooling base 1, so that the tooling cover plate 2 gradually approaches the tooling base 1. In the process of the tooling cover plate 2 moving close to the tooling base 1, the elastic clamping component 5 will be squeezed and generate an extrusion force on the cold plate assembly 4. When the tooling cover plate 2 moves to the preset position, the tooling cover plate 2 remains stable, and the cold plate assembly 4 is clamped between the elastic clamping component 5 and the other of the tooling cover plate 2 and the tooling base 1. In other words, the present application applies a pre-tightening force to the cold plate assembly 4 through the elastic clamping component 5. Even if the cold plate assembly 4 is deformed during the processing, the elastic clamping component 5 can still apply an extrusion force to the cold plate assembly 4, so that the clamping force on the cold plate assembly 4 is maintained during the entire brazing process of the cold plate assembly 4, so that the components of the cold plate assembly 4 are always close together, and the clamping and positioning effect of the cold plate assembly 4 is improved.

[0044] It can be understood that the tooling cover 2 can move relative to the tooling base 1 .

[0045] It is understandable that the structure of the cold plate assembly 4 is relatively complex. In the related art, when a clamp is used to clamp and position the cold plate assembly 4, it is difficult to accurately position the cold plate assembly 4. The gaps at different positions of the cold plate assembly 4 may be inconsistent, and the local gaps are large, which may easily cause the problem of local cold welding. However, the present application uses an elastic clamping assembly 5 to elastically clamp and position the cold plate assembly 4, so that the flow channel plate and cover plate of the cold plate assembly 4 fit tightly, ensuring the consistency of the brazing gap of the cold plate assembly 4 and avoiding the problem of cold welding.

[0046] It is understandable that the positioning clamp in the related art is a clamp. During the brazing process of the cold plate assembly 4, the cold plate assembly 4 will shrink, resulting in the clamp being unable to fully fit the flow channel plate and the cover plate of the cold plate assembly 4, affecting the brazing quality. However, the present application uses an elastic clamping assembly 5 to elastically clamp and position the cold plate assembly 4. When the cold plate assembly 4 shrinks, the elastic clamping assembly 5 will deform accordingly, that is, the elastic clamping assembly 5 will maintain contact with the cold plate assembly 4, and continuously apply a clamping force to the cold plate assembly 4, so that the flow channel plate and the cover plate of the cold plate assembly 4 can always remain in contact.

[0047] According to one embodiment of the present application, Figure 1 As shown, the elastic pressing assembly 5 includes at least two elastic members 51 , a first end of the elastic member 51 is fixedly connected to the tooling cover plate 2 , and a second end of the elastic member 51 faces the tooling base 1 and is used to abut against the cold plate assembly 4 .

[0048] It can be understood that at least two elastic members 51 are arranged between the tooling cover plate 2 and the tooling base 1. When the cold plate assembly 4 is placed on the tooling base 1, the tooling cover plate 2 is controlled to move toward the tooling base 1, and the elastic member 51 moves with the tooling cover plate 2 toward the tooling base 1, so that the second end of the elastic member 51 abuts against the cold plate assembly 4. The tooling cover plate 2 is continued to be controlled to move toward the tooling base 1, so that the elastic member 51 can be compressed, and the elastic member 51 will apply a force toward the tooling base 1 to the cold plate assembly 4, so that the cold plate assembly 4 is clamped and positioned in the installation space 3. At least two elastic members 51 can clamp and position the cold plate assembly 4 at the same time, and can apply elastic clamping force to different positions of the cold plate assembly 4 at the same time, so as to achieve accurate positioning of the cold plate assembly 4 and avoid uneven gaps in the cold plate assembly 4.

[0049] Exemplarily, the elastic member 51 is, for example, a high temperature spring.

[0050] In one embodiment of the present application, Figure 1 As shown, at least two elastic members 51 are distributed at intervals. The second ends of different elastic members 51 are suitable for abutting against different positions of the cold plate assembly 4.

[0051] It can be understood that different elastic members 51 are distributed at different positions at intervals, so that different elastic members 51 can abut against different positions of the cold plate assembly 4 , thereby ensuring the clamping and positioning effect of the cold plate assembly 4 .

[0052] In one embodiment of the present application, an elastic member 51 is provided in the middle of the tooling cover plate 2 , and the elastic member 51 is suitable for abutting against the middle position of the cold plate assembly 4 .

[0053] It can be understood that by arranging the elastic member 51 in the middle of the tooling cover 2, when the tooling cover 2 moves toward the tooling base 1, the elastic member 51 can abut against the middle position of the cold plate assembly 4, thereby overcoming the shortcoming of the related technology that it is difficult to clamp and position the middle position of the cold plate assembly 4, and improving the clamping and positioning effect of the cold plate assembly 4.

[0054] In one embodiment of the present application, Figure 7 As shown, the elastic member 51 includes a rigid member 511 and a spring 512. The spring 512 is sleeved on the rigid member 511. The first end of the rigid member 511 is connected to the tooling cover 2. The second end of the rigid member 511 is suitable for abutting against the cold plate assembly 4. The spring 512 is located between the tooling cover 2 and the second end of the rigid member 511.

[0055] It is understandable that when the tooling cover plate 2 moves toward the tooling base 1, it will drive the second end of the rigid member 511 to move toward the cold plate assembly 4, so that the second end of the rigid member 511 abuts against the cold plate assembly 4, and the cold plate assembly 4 is pressed and positioned by the rigid structure, ensuring that the flow channel plate and the cover plate of the cold plate assembly 4 are fully pressed, and ensuring that the gap is controlled within 0.1mm, which can avoid defects such as local cold welding caused by excessive brazing gap. When the tooling cover plate 2 continues to move toward the tooling base 1, the tooling cover plate 2 will squeeze the spring 512, so that the spring 512 is compressed, and the spring 512 will apply an elastic force to the second end of the rigid member 511. When the cold plate assembly 4 is deformed, the elastic force of the spring 512 can keep the second end of the rigid member 511 pressed and positioned against the cold plate assembly 4.

[0056] In one embodiment of the present application, Figure 1 and Figure 6 As shown, the cold plate positioning tooling includes a connecting rod 6, a first end of the connecting rod 6 is fixedly connected to one of the tooling base 1 and the tooling cover plate 2, the other of the tooling base 1 and the tooling cover plate 2 is provided with a connecting hole, and the second end of the connecting rod 6 is passed through the connecting hole and fixedly connected to the other of the tooling base 1 and the tooling cover plate 2.

[0057] It is understandable that the second end of the connecting rod 6 can move relative to the connecting hole, so that the tooling cover 2 can move relative to the tooling base 1, and the connecting rod 6 can play a guiding and limiting role in the relative movement between the tooling cover 2 and the tooling base 1.

[0058] In one embodiment of the present application, Figure 1 and Figure 5 As shown, the cold plate positioning tooling includes a limit plate 7, which can be switched between a first position and a second position. In the first position, the connecting rod 6 can move relative to the limit plate 7, and in the second position, the connecting rod 6 is clamped to the limit plate 7.

[0059] It is understandable that when the tooling cover plate 2 needs to be moved relative to the tooling base 1, the county party committee office is in the first position, and the connecting rod 6 can move relative to the limit plate 7, that is, the limit plate 7 will not affect the movement of the connecting rod 6, and the tooling cover plate 2 can move relative to the tooling base 1 under the action of external force to adjust the distance between the tooling cover plate 2 and the tooling base 1. After the tooling cover plate 2 is adjusted to a suitable position, it means that the tooling cover plate 2 and the tooling base 1 need to be kept stable at this time, so the limit plate 7 is in the second position, and the connecting rod 6 is clamped on the limit plate 7, that is, the connecting rod 6 can no longer move, and there will be no relative movement between the tooling cover plate 2 and the tooling base 1.

[0060] In one embodiment of the present application, Figure 1 and Figure 5As shown, the limiting plate 7 is formed with a first through hole 71 and a limiting hole 72 which are interconnected, and the connecting rod 6 is formed with a groove 61. In the first position, the connecting rod 6 is passed through the first through hole 71, and the connecting rod 6 can move relative to the first through hole 71. In the second position, the groove 61 is engaged with the limiting hole 72.

[0061] It can be understood that, in the first position, the connecting rod 6 is inserted into the first through hole 71 and can move relative to the first through hole 71, that is, the movement of the connecting rod 6 is not affected, and relative movement can occur between the tooling cover plate 2 and the tooling base 1. In the second position, the groove 61 of the connecting rod 6 is engaged with the limiting hole 72, that is, the connecting rod 6 can no longer move, and relative movement will no longer occur between the tooling cover plate 2 and the tooling base 1. In other words, by moving the limiting plate 7 so that the limiting plate 7 switches between the first position and the second position, the relative movement between the tooling cover plate 2 and the tooling base 1 can be controlled.

[0062] It can be understood that the diameter of the connecting rod 6 at the portion where the groove 61 is located is the same as the diameter of the limiting hole 72 , and the diameter of the limiting hole 72 is smaller than the diameter of the first through hole 71 .

[0063] In one embodiment of the present application, Figure 1 and Figure 6 As shown, at least two grooves 61 are sequentially formed on the connecting rod 6 along the length direction of the connecting rod 6 .

[0064] It is understandable that by forming at least two grooves 61 on the connecting rod 6, when different grooves 61 are engaged with the limiting holes 72, the distance between the tooling cover 2 and the tooling base 1 is different, so that the cold plate positioning tool of the present application can be suitable for different cold plate components 4.

[0065] In one embodiment of the present application, the tooling cover plate 2 is formed with a sliding groove, and the limiting plate 7 is slidably installed in the sliding groove. The sliding groove has a first inner wall surface and a second inner wall surface that are relatively arranged. In the first position, the first end of the limiting plate 7 abuts against the first inner wall surface, and in the second position, the second end of the limiting plate 7 abuts against the second inner wall surface.

[0066] It can be understood that by controlling the movement of the limit plate 7 relative to the sliding groove, the first end of the limit plate 7 abuts against the first inner wall surface of the sliding groove or the second end of the limit plate 7 abuts against the second inner wall surface of the sliding groove, thereby realizing the switching of the limit plate 7 between the first position and the second position.

[0067] In one embodiment of the present application, Figure 1 As shown, a mounting plate 8 is provided on one side of the tooling base 1 facing the tooling cover 2 , and the mounting plate 8 is used to mount the cold plate assembly 4 .

[0068] It can be understood that the installation plate 8 is provided at the tooling base 1 to facilitate the installation of the cold plate assembly 4 .

[0069] It can be understood that the mounting plate 8 is formed with a mounting groove, and the mounting groove can be used to install the cold plate assembly 4.

[0070] In one embodiment of the present application, Figure 1 and Figure 3 As shown, second through holes 21 communicating with the installation space 3 are provided at different positions of the tooling cover plate 2 .

[0071] It can be understood that the cold plate assembly 4 is installed in the installation space 3 between the tooling cover 2 and the tooling base 1. By opening a second through hole 21 in the tooling cover 2, the cold plate assembly 4 can be heated by thermal radiation and the like through the second through hole 21. The second through holes 21 are provided at different positions of the tooling cover 2, so that the cold plate assembly 4 can be heated quickly and the overall temperature uniformity of the cold plate assembly 4 is ensured.

[0072] It is understandable that when the cold plate assembly 4 is brazed, the cold plate assembly 4 is mostly positioned and placed in a vacuum brazing furnace, and the cold plate assembly 4 is heated under a high vacuum condition. In this embodiment, a plurality of second through holes 21 are provided at the tooling cover plate 2, so that the heating energy of the vacuum brazing furnace can be directly radiated to the surface of the cold plate assembly 4 through the second through holes 21, thereby achieving direct thermal radiation heating of the cold plate assembly 4, and second through holes 21 are provided at different positions of the tooling cover plate 2, thereby ensuring the temperature uniformity of various parts of the cold plate assembly 4, improving the heating speed and temperature uniformity, and ensuring the brazing quality.

[0073] In one embodiment of the present application, Figure 1 and Figure 2 As shown, third through holes 11 communicating with the installation space 3 are provided at different positions of the tooling base 1 .

[0074] It can be understood that the cold plate assembly 4 is installed in the installation space 3 between the tooling cover 2 and the tooling base 1. By opening a third through hole 11 in the tooling base 1, the cold plate assembly 4 can be heated by thermal radiation and the like through the third through hole 11. The third through holes 11 are provided at different positions of the tooling base 1, so that the cold plate assembly 4 can be heated quickly and the overall temperature uniformity of the cold plate assembly 4 is ensured.

[0075] It is understandable that when the cold plate assembly 4 is brazed, the cold plate assembly 4 is mostly positioned and placed in a vacuum brazing furnace, and the cold plate assembly 4 is heated under a high vacuum condition. In this embodiment, a plurality of third through holes 11 are provided at the tooling base 1, so that the heating energy of the vacuum brazing furnace can be directly radiated to the surface of the cold plate assembly 4 through the third through holes 11, thereby achieving direct thermal radiation heating of the cold plate assembly 4, and the third through holes 11 are provided at different positions of the tooling base 1, thereby ensuring the temperature uniformity of various parts of the cold plate assembly 4, improving the heating speed and temperature uniformity, and ensuring the brazing quality.

[0076] According to an embodiment of the second aspect of the present application, the cold plate positioning device includes a press and the above-mentioned cold plate positioning tooling, and the press is suitable for driving the tooling cover plate 2 and the tooling base 1 to move relative to each other.

[0077] According to the cold plate positioning device of the embodiment of the present application, it has a cold plate positioning tooling, which applies a pre-tightening force to the cold plate assembly 4 through the elastic clamping assembly 5. Even if the cold plate assembly 4 is deformed during the processing, the elastic clamping assembly 5 can still apply an extrusion force to the cold plate assembly 4, thereby maintaining the clamping force on the cold plate assembly 4 during the entire brazing process of the cold plate assembly 4, so that the components of the cold plate assembly 4 are always tightly together, thereby improving the clamping and positioning effect of the cold plate assembly 4.

[0078] It can be understood that the press at least drives one of the tooling cover plate 2 and the tooling base 1 to move so that the tooling cover plate 2 and the tooling base 1 are at a preset pressure.

[0079] It is understandable that the press can drive the tooling cover plate 2 and / or the tooling base 1 to move, and change the distance between the tooling cover plate 2 and the tooling base 1. For example, the press can drive the tooling cover plate 2 to move toward the tooling base 1, so that the elastic clamping assembly 5 is compressed, and after the tooling cover plate 2 moves to the required position, the press maintains the pressure on the tooling cover plate 2, so that the tooling cover plate 2 remains stable, and then the tooling cover plate 2 and the tooling base 1 remain stable through structures such as limiters or locking members.

[0080] Finally, it should be noted that the above implementation modes are only used to illustrate the present application, rather than to limit the present application. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should be included in the scope of the claims of the present application.
