Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment for electronic devices, and in particular to a rapid cooling device for heat dissipation module processing. Background Technology

[0002] As electronic devices evolve towards high performance and miniaturization, heat dissipation modules often require high-temperature welding or hot pressing during manufacturing. This process generates a high-temperature accumulation effect, which not only affects the microstructure of the module materials but also their subsequent heat dissipation performance. Therefore, how to perform efficient, uniform, and thermal stress-free rapid cooling of heat dissipation modules after manufacturing has become a crucial aspect that urgently needs to be addressed in the manufacturing process of heat dissipation modules.

[0003] Currently, most common cooling technologies for heat dissipation modules on the market employ a single air-cooling or water-cooling method. For example, Chinese patent CN208733203U proposes a cooling solution based on dual fans and a water-cooled plate for a heat dissipation module cooling device. This solution uses fans to accelerate air convection and water-cooled pipes to reduce local temperatures. However, the cooling efficiency of this device is limited by the heat exchange efficiency between air and water, and it cannot achieve rapid cooling in high heat flux processing scenarios.

[0004] The aforementioned literature generally suffers from the following shortcomings: slow cooling response, difficulty in quickly passing through the material's heat-sensitive zone, leading to stress cracks inside the material; and a single cooling method. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid cooling device for heat dissipation module processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid cooling device for processing heat dissipation modules, comprising a transport heat dissipation frame, a support plate at the upper end of the transport heat dissipation frame, a conveyor belt installed inside the transport heat dissipation frame, a liquid nitrogen heat dissipation tank and a heat dissipation frame connected to the upper end of the support plate, a liquid nitrogen input pipe installed on the outer wall of the liquid nitrogen heat dissipation tank, a fixed base and a rotary valve installed at the upper end of the liquid nitrogen input pipe, a water pipe and a water inlet fixedly installed at the upper end of the heat dissipation frame, a fan frame and fixing bolts installed on the outer wall of the support plate and the heat dissipation frame, a heat dissipation fan installed inside the fan frame, an internal protrusion installed inside the liquid nitrogen input pipe, a neoprene rubber base connected to the bottom of the liquid nitrogen input pipe, a liquid nitrogen pipeline installed inside the liquid nitrogen heat dissipation tank, a spray nozzle connected to the bottom of the liquid nitrogen pipeline, and a cooling spray nozzle connected to the bottom of the water pipe.

[0007] As a further description of the above technical solution:

[0008] The conveyor belt is rotatably connected inside the transport heat dissipation frame, the support plate is fixedly connected to the upper end of the transport heat dissipation frame, the liquid nitrogen heat dissipation tank and the heat dissipation frame are integrally connected to the upper end of the support plate, and the liquid nitrogen heat dissipation tank and the heat dissipation frame are fixedly connected.

[0009] As a further description of the above technical solution:

[0010] The water pipes are fixedly installed on the surface of the heat dissipation frame. There are two water pipes. The water inlet is integratedly connected to the upper end of the water pipe and is connected to the water pipe. The cooling spray nozzles are fixedly connected to the bottom of the water pipes. There are several cooling spray nozzles.

[0011] As a further description of the above technical solution:

[0012] The liquid nitrogen input pipe is fixedly connected to the outer wall of the liquid nitrogen heat sink. One end of the liquid nitrogen input pipe is connected to the liquid nitrogen device. The fixed base is fixedly installed on the surface of the liquid nitrogen input pipe. The rotary valve is rotatably connected to the upper end of the fixed base. The liquid nitrogen input pipe has an integrated internal protrusion. The neoprene rubber base is fixedly connected to the bottom of the rotary valve. The size of the neoprene rubber base is the same as the size of the internal protrusion.

[0013] As a further description of the above technical solution:

[0014] The liquid nitrogen pipeline is fixedly connected to one end of the liquid nitrogen input pipe. The liquid nitrogen pipeline is fixedly installed inside the liquid nitrogen heat dissipation tank. The liquid nitrogen input pipe and the liquid nitrogen pipeline are connected. The spray nozzle is fixedly installed at the bottom of the liquid nitrogen pipeline. There are several spray nozzles. The liquid nitrogen pipeline is arranged in a crisscross pattern.

[0015] As a further description of the above technical solution:

[0016] The fan frame is fixedly installed on the outer wall of the liquid nitrogen heat dissipation tank by fixing bolts. There are several fan frames, and the heat dissipation fan is rotatably connected inside the fan frame.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, the device integrates liquid nitrogen spray cooling, water mist-assisted cooling, and air-cooled convection heat dissipation. Instantaneous low-temperature cooling is achieved through liquid nitrogen spray nozzles, suitable for rapid cooling under high heat load conditions. Water pipes, in conjunction with multiple cooling spray nozzles, spray micron-level atomized cold water, maintaining a humid environment during cooling and preventing thermal shock. The cooling fan within the fan frame forms a forced convection air-cooling loop, accelerating the circulation of cold air. These three cooling mechanisms are structurally coupled and complement each other, significantly shortening the module's cooling time and effectively reducing the residence time of thermal stress in the module's thermal stress range.

[0019] By using a support plate as the core platform, the liquid nitrogen cooling tank, cooling frame, and transport cooling rack are integrated into a single unit, resulting in excellent overall stability. A conveyor belt, in conjunction with the transport cooling rack, automatically loads and unloads the cooling modules, making it suitable for continuous processing lines. A crisscrossing arrangement of liquid nitrogen pipelines ensures uniform cooling distribution. The liquid nitrogen input system employs a triple-seal and control structure—rotary valves, neoprene bases, and internal protrusions—ensuring a sealed, stable, and controllable refrigerant supply process. The overall design of the unit is simple and compact, facilitating rapid deployment across different production lines.

[0020] The neoprene rubber base effectively prevents material cracking or operator frostbite caused by liquid nitrogen leakage, while the embedded raised structure further enhances airtightness. All liquid nitrogen paths are controlled by rotary valves, offering flexible adjustment and facilitating manual or remote control via automated monitoring systems. The unobstructed water inlet and pipe structure allow for rapid water replenishment, preventing dry burning or empty spraying. Operation involves no open flames or high voltage, making it highly environmentally friendly and particularly suitable for cooling high-performance heat dissipation modules sensitive to thermal shock.

[0029] Reference Figure 1-4 One embodiment provided by this utility model:

[0030] Example 1:

[0031] A rapid cooling device for processing a heat dissipation module includes a transport heat dissipation frame 1, a support plate 2 at the upper end of the transport heat dissipation frame 1, a conveyor belt 5 installed inside the transport heat dissipation frame 1, a liquid nitrogen heat dissipation tank 3 and a heat dissipation frame 4 connected to the upper end of the support plate 2, a liquid nitrogen input pipe 6 installed on the outer wall of the liquid nitrogen heat dissipation tank 3, a fixed base 7 and a rotary valve 8 installed at the upper end of the liquid nitrogen input pipe 6, a water pipe 9 and a water inlet 10 fixedly installed at the upper end of the heat dissipation frame 4, a fan frame 11 and fixing bolts 12 installed on the outer walls of the support plate 2 and the heat dissipation frame 4, a heat dissipation fan 13 installed inside the fan frame 11, an internal protrusion 15 installed inside the liquid nitrogen input pipe 6, a neoprene rubber base 14 connected to the bottom of the liquid nitrogen input pipe 6, a liquid nitrogen pipe 16 installed inside the liquid nitrogen heat dissipation tank 3, a spray nozzle 17 connected to the bottom of the liquid nitrogen pipe 16, and a cooling spray nozzle 18 connected to the bottom of the water pipe 9.

[0032] Working Principle and Usage: When this rapid cooling device for heat dissipation module processing is in operation, the heat dissipation module is first placed on conveyor belt 5. Conveyor belt 5 then rotates, carrying the heat dissipation module between the liquid nitrogen heat dissipation tank 3 and the heat dissipation frame 4. Liquid nitrogen enters the liquid nitrogen heat dissipation tank 3 through the liquid nitrogen input pipe 6. The internal protrusion 15 inside the liquid nitrogen input pipe 6 effectively prevents eddies during liquid nitrogen transport, improving transport efficiency. The neoprene rubber base 14 matches the size of the internal protrusion 15, ensuring a tight seal between the rotary valve 8 and the liquid nitrogen, preventing leakage. After entering the liquid nitrogen pipe 16, the liquid nitrogen is evenly sprayed onto the heat dissipation module through the spray nozzle 17 for rapid cooling. Simultaneously, cooling water is injected through the water inlet 10 via the water pipe 9. This cooling water is sprayed onto the heat dissipation module through the cooling spray nozzle 18, further accelerating the cooling process. The cooling fan 13 inside the fan frame 11 starts operating, generating airflow and accelerating airflow around the heat dissipation module, improving heat dissipation efficiency. By using liquid nitrogen for rapid cooling, water spray for cooling, and forced air cooling by a fan, the heat dissipation module achieves rapid cooling in a short time, improving processing efficiency.

[0033] Example 2:

[0034] The liquid nitrogen input pipe 6 is fixedly connected to the outer wall of the liquid nitrogen heat sink 3. One end of the liquid nitrogen input pipe 6 is connected to the liquid nitrogen device. The fixed base 7 is fixedly installed on the surface of the liquid nitrogen input pipe 6. The rotary valve 8 is rotatably connected to the upper end of the fixed base 7. The liquid nitrogen input pipe 6 has an integrated internal protrusion 15. The neoprene rubber base 14 is fixedly connected to the bottom of the rotary valve 8. The size of the neoprene rubber base 14 is the same as the size of the internal protrusion 15.

[0035] The liquid nitrogen pipeline 16 is fixedly connected to one end of the liquid nitrogen input pipe 6. The liquid nitrogen pipeline 16 is fixedly installed inside the liquid nitrogen heat sink 3. The liquid nitrogen input pipe 6 and the liquid nitrogen pipeline 16 are connected. The spray nozzle 17 is fixedly installed at the bottom of the liquid nitrogen pipeline 16. There are several spray nozzles 17. The liquid nitrogen pipeline 16 is arranged in a crisscross pattern.

[0036] The improvement of this embodiment over the prior art lies in the following: by incorporating an integrated internal protrusion 15 inside the liquid nitrogen input pipe 6 and fitting it in a size-matched manner with the neoprene rubber base 14, a flexible sealing mechanism that is leak-free, resistant to freeze-thaw cycles, and resistant to aging is constructed. This structure provides an automatic buffer sealing effect during the opening / closing of the rotary valve 8, preventing refrigerant leakage during unstable liquid nitrogen flow or spraying, significantly improving the operational safety and reliability of the device in an extremely low temperature environment of -196℃, and avoiding the formation of condensation or ice in the operating area.

[0037] By designing the liquid nitrogen pipes 16 in a crisscross pattern, a three-dimensional interlaced liquid supply network is constructed, effectively improving the spatial coverage of liquid nitrogen inside the heat dissipation tank 3. This allows the liquid nitrogen to flow evenly through all areas and be precisely released onto the surface of the heat dissipation module through the spray nozzles 17. Compared with existing structures that only have unidirectional or ring-shaped pipes, this solution can significantly reduce local cooling blind spots, making it particularly suitable for rapid cooling of irregularly shaped modules or multi-unit side-by-side modules.

[0038] The number of spray nozzles 17 is set to several and located at the bottom of the liquid nitrogen pipeline, so that liquid nitrogen is sprayed vertically at high pressure onto the module surface, which helps to form a "cold mist impact layer". This layout not only achieves rapid heat absorption and low temperature impact, but also, combined with the spray angle design, enhances the atomization area, improves heat exchange efficiency, and avoids thermal stress concentration caused by direct impact of liquid nitrogen on the module structure.

[0039] Example 3:

[0040] The conveyor belt 5 is rotatably connected inside the transport heat dissipation frame 1, the support plate 2 is fixedly connected to the upper end of the transport heat dissipation frame 1, the liquid nitrogen heat dissipation box 3 and the heat dissipation frame 4 are integratedly connected to the upper end of the support plate 2, and the liquid nitrogen heat dissipation box 3 and the heat dissipation frame 4 are fixedly connected.

[0041] Water pipes 9 are fixedly installed on the surface of heat dissipation frame 4. There are two water pipes 9. Water inlet 10 is integratedly connected to the upper end of water pipe 9. Water inlet 10 is connected to water pipe 9. Cooling spray nozzles 18 are fixedly connected to the bottom of water pipe 9. There are several cooling spray nozzles 18.

[0042] The improvement of this embodiment over the prior art lies in the following: In this embodiment, the liquid nitrogen heat sink 3 and the heat dissipation frame 4 are integrated and connected to the support plate 2, and the support plate 2 is further fixedly installed on the upper end of the transport heat dissipation frame 1, forming a stable double-layer composite structure that provides upper support for cooling and lower support for transport. This design avoids the problem of separation between the cooling unit and the transport unit, significantly reduces vibration interference and component misalignment risks during operation, improves the dynamic stability of the equipment and the adaptability of various heat dissipation module specifications, and is especially suitable for the automated cooling integration needs in assembly line operation scenarios.

[0043] This design incorporates two symmetrical water pipes 9 on the surface of the heat dissipation frame 4, with multiple cooling spray nozzles 18 at the bottom of each pipe. This combination of symmetrical layout and multi-point spraying achieves large-area, multi-angle cooling coverage for multiple modules on the conveyor belt. The water inlet 10 is integrated with the water pipes 9, ensuring a smooth water replenishment path and high integration, facilitating the setup of an automatic water replenishment control system. The water pipe structure is fixed to the surface of the heat dissipation frame, reducing vibration interference and interface fatigue. Several cooling spray nozzles 18 are distributed at the bottom of the pipes and can be adjusted using different flow valves to meet the requirements of different processing techniques regarding atomized cooling intensity and distribution.

[0044] Example 4:

[0045] The fan frame 11 is fixedly installed on the outer wall of the liquid nitrogen heat sink 3 by fixing bolts 12. There are several fan frames 11, and the heat dissipation fan 13 is rotatably connected to the inside of the fan frame 11.

[0046] The improvement of this embodiment over the prior art lies in the following: by rotatably mounting the cooling fan 13 inside the fan frame 11, and securely mounting the fan frame to the outer wall of the liquid nitrogen cooling tank 3 with fixing bolts 12, a stable, controllable, and repeatedly operating active air-cooling unit system is formed. This air-cooling system can quickly remove residual condensate or heat from the surface after liquid nitrogen and water cooling, opening up the heat migration path between the low-temperature zone and the outside air, and accelerating the overall heat exchange cycle efficiency between the module and the cooling system.

[0047] This solution uses multiple fan frames (11 modules) distributed outside the liquid nitrogen heat sink, which can flexibly adjust the number and position of the fans. Based on the module size, arrangement and heat load distribution differences, the air supply angle and airflow path can be reasonably configured to achieve directional purging and zoned heat dissipation functions.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
