Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultra-thin water-cooled heat dissipation module technology, and more specifically to a highly integrated ultra-thin liquid cooling conversion interface. Background Technology
[0002] Most existing water-cooling modules adopt an axial water inlet and horizontal water outlet design. With the trend of product thinning and lightening, the interface design of existing modules can no longer meet the usage requirements when the height is strictly limited. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a highly integrated ultra-thin liquid-cooled conversion interface.
[0004] The technical solution of this utility model is as follows:
[0005] A highly integrated ultra-thin liquid-cooled conversion interface includes a conversion interface body, a water inlet connector, and a water outlet connector; the conversion interface body is provided with a water inlet connector and a water outlet connector on one side, and two water-cooled pipe connectors on the other side, which are respectively connected to the water inlet connector and the water outlet connector.
[0006] The outer walls of the inlet and outlet connectors are provided with steps, and sealing rings are fitted at the steps for sealing connection with the inlet and outlet of the water pump, respectively.
[0007] The water-cooled pipe joint is directly brazed to the copper water-cooled pipe / water-cooled plate.
[0008] The conversion interface body has a liquid injection port, which is connected to the water outlet connector and is secured by screws and sealing washers.
[0009] The replacement interface body, water inlet connector, water outlet connector, two water cooling pipe connectors, and liquid injection port adopt an integrated molding structure.
[0010] The conversion interface body has multiple through holes for being locked onto the water pump with bolts.
[0011] The conversion interface body is equipped with guide posts to facilitate positioning when inserting into the water pump.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. The absence of an additional E-buckle or O-buckle anti-drop structure reduces the overall cost of the product, making it more competitive in the market.
[0014] 2. The structure is simple and easy to understand, with a high yield rate, making it suitable for large-scale mass production.
[0015] 3. Meets the requirements for pump docking and liquid injection in ultra-thin environments.
[0016] 4. The water-cooled pipe joint is directly brazed to the copper water-cooled pipe / water-cooled plate, which is simple in structure. This structure can meet the horizontal docking of the water pump and the water-cooled plate without the need to use a hose to connect to the pump, which is highly reliable and reduces the risk of leakage.
[0017] 5. The injection port and the outlet connector are integrated, avoiding the need to add openings to the water pump, which would affect the structural strength of the pump body and increase reliability; Attached Figure Description
