Description

Technical Field

[0001] The invention relates to the technical field of liquid cooling product flow channel processing, and in particular provides a liquid cooling punching and pressure relief integrated tooling. Background Art

[0002] In the prior art, some modules dissipate heat through liquid cooling. These modules are welded by vacuum brazing during the processing process. After welding, in order to test its welding performance, the pressure-maintaining method is used to test its sealing, and the flow channel is cleaned by high-pressure flushing. At present, the flushing and pressure-maintaining equipment is directly connected to the water inlet and outlet of the liquid cooling module through threads. Since the liquid cooling module is an aluminum product with low material hardness, the threads are prone to thread slippage and tooth decay during repeated disassembly and assembly, causing the product to be scrapped. The aluminum chips generated are also easy to enter the flow channel and become excess material to block the liquid cooling system, causing the product to overheat and shut down. At the same time, the flow channel of liquid cooling products needs to be closed during storage and transportation to prevent foreign matter from entering the internal contamination of the flow channel. In the absence of ventilation, the internal pressure is likely to increase, causing the product to bulge and crack, resulting in product scrapping. Summary of the invention

[0003] The purpose of the present application is to provide an integrated liquid cooling flushing and pressure relief tooling to reduce the number of connections between the flushing and pressurizing equipment and the liquid cooling inlet and outlet, reduce damage to the liquid cooling module during the liquid cooling process, and at the same time be waterproof and breathable, thereby avoiding contamination of the liquid cooling module flow channel and bulging and cracking during storage and transportation.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a liquid-cooled punching and pressure-relieving integrated tooling, the tooling comprising: a male head component and a female head component arranged in coordination with each other,

[0005] The male head assembly includes an internal thread male head and an O-ring fixed on the internal thread male head for sealing between the male head assembly and the female head assembly.

[0007] When the tooling is in the flushing state, the male assembly cooperates with the female assembly, the top of the male assembly pushes the valve core open, the spring is compressed, and a liquid flow channel is formed between the outer side of the top of the male assembly and the inner side of the valve housing, and the top of the male assembly is attached to the waterproof and breathable membrane.

[0008] When the tooling is in an open state, the male assembly is separated from the female assembly, the spring is stretched, and the valve core is pressed, so that the outer side of the valve core contacts the inner side of the valve housing, and the fluid channel is closed.

[0009] The integrated liquid-cooling punching and pressure-relieving tooling provided by the present invention also has such a technical feature that a flow channel hole for forming a fluid flow channel is provided on the side of the internal thread male head push rod.

When the tooling is in the flushing state, the male component cooperates with the female component, the top end of the male component pushes the valve core 5 open, the spring 7 is compressed, and a liquid flow channel is formed between the outer side of the top end of the male component and the inner side of the valve housing 3. The top end of the male component fits the waterproof breathable membrane 4. When the tooling is in the open state, the male component is separated from the female component, the spring 7 is stretched, and the valve core 5 is pressed. The outer side of the valve core 5 contacts the inner side of the valve housing 3, and the fluid channel is closed.

[0028] In some embodiments, a flow channel hole for forming a fluid flow channel is provided on the side of the push rod of the female thread male connector 1.

[0029] In some embodiments, the push rod of the female thread male connector 1 is provided with a lock buckle for disassembly and assembly.

[0030] In some embodiments, a sealing layer for sealing is provided at a position where the inner side of the valve housing 3 contacts the outer shell of the valve core 5 .

[0031] In some embodiments, the sealing layer is a coating selected from silicon carbide ceramics, fluororubber and nitrile rubber.

[0032] In some embodiments, the waterproof breathable membrane 4 is a non-woven fabric structure, and the diameter of the breathable portion of the waterproof breathable membrane 4 is the same as the hollow diameter of the valve core 5 .

[0033] In some embodiments, a chamfer for self-sealing is provided at a contact position between the outer shell of the valve core 5 and the inner side of the valve housing 3 .

[0034] In some embodiments, the adapter 8 is made of pure copper.

[0035] In some embodiments, the length of the adapter end of the adapter 8 is greater than the height of the product boss.

[0036] The working process of the liquid-cooled stamping integrated tooling provided in any of the above embodiments is as follows:

[0037] 1. During flushing and pressurization, the internal thread male head 1 is locked with the valve housing 3 by pushing, pulling and rotating. The other end of the valve housing 3 is connected to the female head housing 6 by a thread. An O-ring 2 is installed on the internal thread male head 1. The right end of the internal thread male head 1 is pressed against the waterproof breathable membrane 4. The waterproof breathable membrane 4 is fixed on the valve core 5. The spring 7 between the right end of the valve core 5 and the inside of the female head housing 6 is in a compressed state. The reaction force applied by the spring 7 to the valve core 5 makes the valve core 5, the internal thread male head 1 and the waterproof breathable membrane 4 tightly connected. The valve core 5 moves backward to form a connecting flow channel on the side of the valve core 5. The other end of the female head housing 6 is connected to the conversion head 8 by a thread. The other end of the conversion head 8 is connected to the inlet and outlet of the liquid cooling module.

[0038] 2. When releasing pressure during storage and transportation, the female thread male connector 1 is disconnected from the valve housing 3. Since the spring 7 is in a compressed state when maintaining pressure, after the female thread male connector 1 is removed, the spring 7 pushes the valve core 5 to the inner wall of the valve housing 3, and the side flow channel of the valve core 5 is squeezed and closed by the valve core 5. At this time, due to the action of the waterproof breathable membrane 4, the internal pressure of the liquid cooling module can still be released.

[0039] The working principle of the integrated liquid-cooling stamping tooling provided by any of the above-mentioned embodiments is as follows: during punching and stamping, the female thread male connector 1 is quickly locked with the valve housing 3 by pushing, pulling and rotating, and the right end of the core rod of the female thread male connector 1 presses against the valve core 5 to protect the waterproof and breathable membrane 4 in the middle of the valve core 5. At the same time, the valve core 5 is pushed and moved backward to form a connecting flow channel on the side, and the high-pressure and high-speed water flows into the liquid cooling module through the side hole of the core rod of the female thread male connector 1 and the side of the valve core 5. When pressure relief is required during storage and transportation, the female thread male connector 1 is disconnected from the valve housing 3, and the compression spring 7 presses the valve core 5 against the inner wall of the valve housing 3 to close the flow channel. Due to the action of the waterproof and breathable membrane 4, the internal high-pressure gas slowly discharges from the inside of the liquid cooling module to achieve the effect of pressure relief protection.

[0040] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
