Description

Technical Field

[0001] This application relates to the field of semiconductor technology, and more specifically to a cooling device. Background Technology

[0002] Power Cycling Test (PCT) is a key component in the reliability assessment of automotive products and high-performance industrial modules. It simulates real-world thermal cycling conditions to verify the module's stability during long-term operation. Currently, traditional power cycling equipment generally employs a flat-panel cooling structure, which is only compatible with modules requiring single-sided cooling. For reliability testing of double-sided cooling modules (DSC), dedicated cooling equipment must be designed to meet the heat dissipation requirements.

[0003] Due to differences in application scenarios, double-sided heat dissipation modules have evolved into two structural designs: horizontal and vertical. The main difference in appearance lies in the shape of the power and signal terminals. However, the cooling equipment for these two types of double-sided heat dissipation modules is designed independently, leading to the following technical problems: the water-cooling equipment corresponding to the vertical and horizontal structures of the double-sided heat dissipation modules is not interchangeable, resulting in low experimental efficiency and high total investment in spare parts for water-cooling equipment.

[0004] In view of the above-mentioned technical problems, this application provides a new cooling device to at least partially solve the above problems. Utility Model Content

[0035] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with this application.

[0036] It should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of this application to those skilled in the art. In the drawings, for clarity, the dimensions and relative dimensions of layers and regions may be exaggerated. The same reference numerals denote the same elements throughout.

[0037] It should be understood that when an element or layer is referred to as "on," "adjacent to," "connected to," or "coupled to" other elements or layers, it may be directly on, adjacent to, connected to, or coupled to other elements or layers, or there may be intervening elements or layers. Conversely, when an element is referred to as "directly on," "directly adjacent to," "directly connected to," or "directly coupled to" other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc., may be used to describe various elements, components, areas, layers, and / or portions, these elements, components, areas, layers, and / or portions should not be limited by these terms. These terms are only used to distinguish one element, component, area, layer, or portion from another element, component, area, layer, or portion. Therefore, without departing from the teachings of this application, the first element, component, area, layer, or portion discussed below may be referred to as the second element, component, area, layer, or portion.

It should be understood that, in addition to the orientation shown in the figure, spatial relation terms are intended to also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, then the element or feature described as “below” or “under” the other element or feature will be oriented “above” the other element or feature. Therefore, the exemplary terms “below” and “under” can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or otherwise) and the spatial descriptive terms used herein will be interpreted accordingly.

[0039] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. When used herein, the singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising” and / or “including,” when used in this specification, identify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups. When used herein, the term “and / or” includes any and all combinations of the associated listed items.

[0040] Dual-sided heat dissipation modules, based on different application scenarios, have evolved into two structural designs: horizontal and vertical. The main difference in appearance lies in the shape of the power terminals and signal terminals. For example, Figure 1 (a) shows a schematic diagram of a horizontal double-sided heat dissipation module, which has horizontally structured terminals 110. Figure 1 (b) shows a schematic diagram of a vertical double-sided heat dissipation module with terminals 120 in a vertical structure.

[0041] However, the independent design of cooling devices for the two types of double-sided heat dissipation modules in related technologies leads to the following technical problems:

[0042] Firstly, the vertical and horizontal structures of the double-sided heat dissipation module are not compatible with each other for water cooling equipment. If the type of double-sided heat dissipation module needs to be switched during the experiment, the entire water cooling equipment needs to be disassembled and replaced. This involves tedious steps such as water pipe disassembly, water channel cleaning, sealing ring inspection and reinstallation. A single switch takes 1 to 1.5 hours, which seriously affects the experimental efficiency. In addition, it is necessary to keep spare parts for both types of water cooling equipment, which increases the equipment investment cost.

[0043] Secondly, the terminals of the double-sided heat dissipation module are directly fixed to the base of the water-cooling equipment. The heat generated by the module is directly conducted to the base. At the same time, the mechanical stress during fixing is also concentrated on the base, causing the base to be subjected to high-temperature aging stress during the experiment, which is prone to carbonization and leads to failures during later installation.

[0044] To address at least one of the aforementioned technical problems, this application provides a cooling device suitable for a double-sided heat dissipation module, the double-sided heat dissipation module having a detachable second terminal, the second terminal including a vertical second terminal or a horizontal second terminal, the cooling device comprising:

[0045] A base, wherein the base is provided with an installation area for mounting the double-sided heat dissipation module;

[0046] The first cooling plate and the second cooling plate are respectively disposed on two opposite surfaces of the double-sided heat dissipation module, and refrigerant can be introduced into the first cooling plate and the second cooling plate.

[0047] The first terminal is provided on the base, which has a slot for mounting the first terminal;

[0048] A fixing component is configured to fix the vertical second terminal or the horizontal second terminal to the first terminal along different fixing directions.

[0049] According to the cooling device of this application, by using a detachable vertical / horizontal second terminal in conjunction with a fixing component that can be adjusted and fixed in direction, the same cooling device can be compatible with double-sided heat dissipation modules of different structures, which solves the problems of low efficiency and high spare parts cost caused by the non-universality of water cooling devices in related technologies. At the same time, the design of the second terminal indirectly connecting to the base through the first terminal avoids the base directly bearing heat and stress, solves the problem of base carbonization failure, and achieves dual optimization of compatibility and reliability.

[0050] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solutions proposed in this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0051] The following is for reference. Figures 2-5 A cooling device according to an embodiment of this application is described. The cooling device is suitable for a double-sided heat dissipation module 300, the double-sided heat dissipation module 300 having a detachable second terminal, the second terminal including a vertical second terminal 312 or a horizontal second terminal 311, the cooling device comprising:

[0052] The base 210 has an installation area for mounting the double-sided heat dissipation module 300.

[0053] The first cooling plate 221 and the second cooling plate 222 are respectively disposed on two opposite surfaces of the double-sided heat dissipation module 300. Refrigerant can be introduced into the first cooling plate 221 and the second cooling plate 222 to dissipate heat on the corresponding surfaces of the double-sided heat dissipation module 300.

[0054] The first terminal 230 has a slot 211 on the base 210 for mounting the first terminal 230;

[0055] The fixing component is configured to fix the vertical second terminal 312 or the horizontal second terminal 311 to the first terminal 230 in different fixing directions.

[0056] On one hand, the second terminal of the double-sided heat dissipation module 300 is a detachable vertical second terminal 312 or a horizontal second terminal 311, which is electrically connected to the second terminal through the first terminal 230 in the slot 211 of the base 210. The fixing component can be adjusted to fix the direction, so that the same cooling equipment can be adapted to different types of second terminals (vertical / horizontal). For example, when it is necessary to switch the type of the double-sided heat dissipation module 300, only the second terminal needs to be replaced and the direction of the fixing component needs to be adjusted. There is no need to disassemble the base 210 and cooling plate and other components, avoiding the defect of needing to customize two sets of water cooling equipment in related technologies. This realizes that one cooling equipment is compatible with two types of double-sided heat dissipation modules 300, reduces spare parts investment costs and improves experimental switching efficiency.

[0057] On the other hand, a slot 211 is provided on the base 210, and the first terminal 230 is installed in the slot 211. The vertical / horizontal second terminal 311 is fixedly electrically connected to the first terminal 230 through a fixing component, so that the second terminal does not directly contact the base 210. This structural design cuts off the heat conduction path from the second terminal to the base 210, while the fixing component bears the mechanical stress during connection, preventing the base 210 from being subjected to high-temperature stress. Since the base 210 only serves as a mounting carrier and is no longer directly affected by high temperature and stress, carbonization of the base 210 is effectively prevented, the risk of installation failure is reduced, and the service life is extended, saving maintenance costs and waiting time.

[0058] In some embodiments, the base 210 is configured to be mounted on a power circulation device, which is configured to be electrically connected to the first terminal 230.

[0059] For example, the base 210 is specifically configured to be installed on a preset mounting surface of the power circulation device by a mechanical fixing structure (such as a positioning pin, bolt group or snap-fit ​​assembly). The mounting surface has a positioning groove or screw hole array that matches the shape of the base 210 to ensure the mechanical connection stability between the base 210 and the power circulation device.

[0060] The first terminal 230 serves as an intermediate carrier for electrical connection and is located in the slot 211 of the base 210. The power circulation device forms a conductive connection with the first terminal 230 through its internal conductive lines or external conductive busbars, thereby establishing an electrical connection path between the double-sided heat dissipation module 300 and the power circulation device.

[0061] In some embodiments, such as Figure 2 and Figure 3 As shown, the first cooling plate 221 and the second cooling plate 222 are respectively disposed on the upper surface and the lower surface of the double-sided heat dissipation module 300. Refrigerant can be introduced into the first cooling plate 221 and the second cooling plate 222 to dissipate heat on the upper surface and the lower surface of the double-sided heat dissipation module 300.

[0062] In some embodiments, such as Figure 2 and Figure 3 As shown, both the first cooling plate 221 and the second cooling plate 222 are provided with an inlet connector 223 and an outlet connector 224. Both the first cooling plate 221 and the second cooling plate 222 are connected to the output end of an external refrigerant supply device through their respective inlet connectors 223, and both the first cooling plate 221 and the second cooling plate 222 are connected to the return end of an external refrigerant supply device through their respective outlet connectors 224.

[0063] Taking the first cooling plate 221 as an example, it is equipped with an inlet connector 223 and an outlet connector 224 at both ends. Both types of connectors adopt a fluid-sealed connection structure (such as a threaded interface, quick-connect connector, or flange interface) to ensure a reliable connection with the external refrigerant supply equipment. Specifically, the inlet connector 223 is connected to the output end of the refrigerant supply equipment through a flexible or rigid pipe to introduce low-temperature refrigerant into the cooling plate; the outlet connector 224 is connected to the return end of the refrigerant supply equipment through a pipe to form a refrigerant circulation loop. When the refrigerant flows through the cooling plate, it absorbs heat from the surface of the double-sided heat dissipation module 300 through heat exchange, thereby achieving the cooling and heat dissipation function of the module. The structure of the second cooling plate 222 can be referred to the description of the first cooling plate 221 above, and will not be repeated here.

[0064] The refrigerant can be deionized water, ethylene glycol solution, propylene glycol solution, mineral oil, etc., and there are no restrictions on its use.

[0065] In some embodiments, the first terminal 230 is made of a conductive metal material and has a corrosion-resistant plating layer on its surface to resist environmental erosion of the first terminal 230 and ensure the long-term reliability of the electrical connection between the double-sided heat dissipation module 300 and the power circulation device. For example, the first terminal 230 may be made of copper with nickel plating on its surface.

[0066] In some embodiments, such as Figure 4 and Figure 5 As shown, the first terminal 230 includes a first connecting portion 231 and a second connecting portion 232 that are bent and connected. The first connecting portion 231 is configured to be disposed in the slot 211. The fixing component is configured such that: when the second terminal is a vertical second terminal 312, the vertical second terminal 312 is fixedly electrically connected to the second connecting portion 232 along the first fixing direction; when the second terminal is a horizontal second terminal 311, the horizontal second terminal 311 is fixedly electrically connected to the second connecting portion 232 along the second fixing direction; wherein, the first fixing direction is perpendicular to the second fixing direction.

[0067] Specifically, the first connecting part 231 is embedded in the slot 211 of the base 210, and the second connecting part 232 serves as the exposed connecting interface. When it is necessary to replace the vertical double-sided heat dissipation module 300 or the horizontal double-sided heat dissipation module 300, it is only necessary to remove the corresponding type of second terminal: if the original second terminal is vertical, the fixing component set along the first fixed direction needs to be released, and the vertical second terminal 312 is removed from the second connecting part 232; if the original second terminal is horizontal, the fixing component set along the second fixed direction is released, and the horizontal second terminal 311 is removed from the second connecting part 232. Subsequently, a new terminal is installed: for the horizontal second terminal 311, it is fixedly electrically connected to the second connecting part 232 along the second fixed direction; for the vertical second terminal 312, it is fixedly electrically connected to the second connecting part 232 along the first fixed direction.

[0068] For example, such as Figure 4 and Figure 5 As shown, the first fixed direction can be a horizontal direction parallel to the plane of the base 210, and the second fixed direction can be a vertical direction perpendicular to the plane of the base 210. Alternatively, the first fixed direction and the second fixed direction can be any other suitable direction, without limitation.

[0069] Since the first fixing direction is perpendicular to the second fixing direction, the same second connecting part 232 can be adapted to two types of terminals by fixing the fixing components at different angles. During the whole process, the base 210 and cooling plate and other components do not need to be disassembled. Different types of terminals can be replaced simply by adjusting the direction of the fixing components, thereby adapting to vertical or horizontal double-sided heat dissipation modules 300. This makes the same cooling equipment compatible with vertical / horizontal double-sided heat dissipation modules 300, solving the efficiency and cost problems of non-universal water cooling equipment in related technologies.

[0070] Furthermore, the second terminal is not directly fixed to the base 210, but is indirectly connected through the second connecting portion 232 of the first terminal 230. The stress of the fixing component is conducted to the slot 211 of the base 210 through the first connecting portion 231, rather than acting directly on the surface of the base 210; at the same time, the heat generated by the second terminal is mainly conducted through the metal structure of the first terminal 230, and the base 210 only serves as a mounting carrier and does not directly bear the high-temperature stress. This design cuts off the heat conduction path and transfers mechanical stress, preventing the base 210 from aging and carbonizing due to high temperature.

[0071] In some embodiments, such as Figure 5As shown, the vertical second terminal 312 includes a first bent portion 3121 and a second bent portion 3122 connected by bending. The first bent portion 3121 is electrically connected to the chip of the double-sided heat dissipation module 300. The fixing component is configured such that the second bent portion 3122 is fixedly electrically connected to the side surface of the second connecting portion 232 along a first fixing direction, and the first bent portion 3121 is at least partially attached to the upper surface of the second connecting portion 232. Figure 4 As shown, the horizontal second terminal 311 includes a straight portion, and the fixing assembly is configured to fix the straight portion to the upper surface of the second connection portion 232 along the second fixing direction.

[0072] Specifically, when it is necessary to replace the vertical double-sided heat dissipation module 300 or the horizontal double-sided heat dissipation module 300, it is only necessary to remove the corresponding type of second terminal: if the original second terminal is vertical, the fixing component set along the first fixed direction (e.g., perpendicular to the side surface of the second connecting part 232) needs to be released, and the vertical second terminal 312 is removed from the side surface of the second connecting part 232; if the original second terminal is horizontal, the fixing component set along the second fixed direction (e.g., perpendicular to the upper surface of the second connecting part 232) needs to be released, and the horizontal second terminal 311 is removed from the upper surface of the second connecting part 232. Subsequently, new terminals are installed: For the horizontal second terminal 311, its straight portion is placed on the upper surface of the second connecting portion 232 and fixed along the second fixing direction using a fixing assembly to achieve electrical connection and mechanical fixation of the horizontal structure; for the vertical second terminal 312, its bent portion 3122 is aligned with the side surface of the second connecting portion 232 and fixed along the first fixing direction using a fixing assembly, and the first bent portion 3121 is at least partially attached to the upper surface of the second connecting portion 232 to achieve electrical connection and mechanical fixation of the vertical structure. Throughout the process, components such as the base 210 and cooling plate do not need to be disassembled; different types of terminals can be replaced simply by adjusting the direction (vertical or horizontal) of the fixing assembly, thereby adapting to the vertical or horizontal double-sided heat dissipation module 300.

[0073] In some embodiments, such as Figure 4 and Figure 5As shown, the fixing assembly includes a pad 241 and a fastener 242. The height of the pad 241 matches the height of the second connecting portion 232, and the pad 241 has a threaded hole. The fixing assembly is configured as follows: when the second terminal is a vertical second terminal 312, the pad 241 is disposed on the first connecting portion 231 with the threaded hole extending along the first fixing direction. The fastener 242 is disposed in the threaded hole to fix the second bent portion 3122 between the side surface of the second connecting portion 232 and the pad 241, and the first bent portion 3121 is at least partially attached to the upper surface of the second connecting portion 232. When the second terminal is a horizontal second terminal 311, the pad 241 is disposed on the first connecting portion 231 with the threaded hole extending along the second fixing direction. The straight portion of the horizontal second terminal 311 is located on the upper surface of the second connecting portion 232 and the pad 241, and is fixed by the fastener 242 disposed in the threaded hole. The fastener 242 can be a screw or the like, and is not limited thereto.

[0074] When replacing the vertical and horizontal double-sided heat dissipation modules 300, firstly, disconnect the original connection between the second terminal and the first terminal 230 by removing the fastener 242: For the vertical double-sided heat dissipation module 300, loosen and remove the fastener 242 set along the first fixed direction, and remove the pad 241. At this time, the second bent portion 3122 of the vertical second terminal 312 (originally sandwiched between the side surface of the second connecting portion 232 and the pad 241) loses the limiting effect of the pad 241, causing the second bent portion to... 3122 separates from the side surface of the second connecting part 232, and the first bent part 3121 separates from the upper surface of the second connecting part 232. The vertical second terminal 312 is removed. For the horizontal double-sided heat dissipation module 300, the fastener 242 set along the second fixed direction is loosened and removed. At this time, the straight part of the horizontal second terminal 311 loses the fixing effect of the fastener 242, so that the straight part separates from the upper surface of the second connecting part 232. The horizontal second terminal 311 and the pad 241 are removed. Subsequently, install the new second terminal: When replacing with a horizontal double-sided heat dissipation module 300, reset the pad 241 on the first connecting part 231, so that the threaded hole is set along the second fixing direction parallel to the plane of the base 210. Place the straight part of the horizontal second terminal 311 horizontally on the upper surface of the second connecting part 232 and the pad 241, ensuring that the straight part is in contact with the first terminal 230, and then fix it by fasteners 242 passing through the threaded hole, so as to achieve reliable fixation of the horizontal second terminal 311 on the upper surface of the second connecting part 232; when replacing with a vertical double-sided heat dissipation module 300, The second bent portion 3122 of the vertical second terminal 312 is fitted to the side surface of the second connecting portion 232, and the first bent portion 3121 of the vertical second terminal 312 is fitted to the upper surface of the second connecting portion 232. Then, the pad 241 is placed on the first connecting portion 231 of the base 210, and the threaded hole of the pad 241 is set along the first fixing direction, thereby clamping and fixing the second bent portion 3122 between the side surface of the second connecting portion 232 and the pad 241. Pressure is applied by screwing the fastener 242 into the threaded hole, so that the second bent portion 3122 is clamped and fixed.

[0075] The above process, through the directional adjustment of the pad 241 and the fixing effect of the fastener 242, enables the rapid switching between two different types of modules without disassembling the base 210 and cooling plate, ensuring reliable electrical connection between the second terminal and the first terminal 230 and the universality of the heat dissipation system. Moreover, by only replacing the pad 241 and the fastener 242, much of the disassembly process is eliminated, saving time and improving experimental efficiency.

[0076] In some embodiments, the second terminal includes a power terminal and a signal terminal.

[0077] According to another aspect of this application, a power cycling test system is provided, including a power cycling device, a double-sided heat dissipation module, and a cooling device; the base of the cooling device is mounted on the power cycling device, and the double-sided heat dissipation module is mounted in the mounting area.

[0078] The cooling equipment can be the same as the cooling equipment mentioned above, which can be referred to in the above description and will not be repeated here.

[0079] In summary, the cooling device according to the embodiments of this application, through the cooperation of a detachable vertical / horizontal second terminal and an adjustable fixing component, enables the same cooling device to be compatible with double-sided heat dissipation modules of different structures, solving the problems of low efficiency and high spare parts cost caused by the incompatibility of water cooling devices in related technologies; at the same time, the design of the second terminal indirectly connecting to the base through the first terminal avoids the base directly bearing heat and stress, solving the problem of base carbonization failure, and achieving dual optimization of compatibility and reliability.
