Description

Technical Field

[0001] The present invention relates to the technical field of cooling of cabinet-type electronic equipment, in particular to a compact and efficient universal cooling liquid cooling plug-in box. Background Art

[0002] As electronic equipment continues to evolve toward integration, modularization, and high integration, the heat dissipation and heat flux density of electronic modules are increasing. Currently, cabinet subracks typically dissipate heat through natural convection or forced air cooling. However, electronic plug-ins using air cooling, when using vapor chamber technology, have a maximum heat dissipation of approximately 100W, while the subracks have a maximum heat dissipation of approximately 800W. This no longer meets the requirements of 200W heat dissipation for electronic plug-ins and 1600W heat dissipation for subracks. Furthermore, air cooling has drawbacks such as high noise levels and large air duct footprints. Compared to air-cooled subracks, liquid-cooled subracks offer high heat dissipation efficiency, strong heat dissipation capacity, and low noise levels, meeting the evolving needs of current electronic equipment heat dissipation.

[0003] The currently disclosed patent CN109661157A involves a new liquid-cooled chassis, which includes a left side plate. The internal flow channel of the left side plate is composed of a hose and several liquid-cooling adapters, which can separate the electronic modules inside the plug-in box from the water channel, ensuring the safety of the electronic equipment. However, due to the numerous internal pipe interfaces of the left side plate, the risk of leakage is high, and the thickness of the left side plate is large, the utilization rate of the internal space of the plug-in box is low; microchannel flow channels are used inside the upper and lower cold plates, which have good heat dissipation effects, but the processing and welding are complicated, the quality requirements of the coolant are high, and the microchannels are easy to clog; the inlet and outlet interfaces of the chassis coolant are on the same side, and the connectors are bayonet-type fluid connectors, which cannot be blindly plugged on the cabinet rack, and the flexibility and maintainability are poor. Summary of the Invention

[0004] The object of the present invention is to provide a liquid cooling plug-in box with a compact structure, large available space, high reliability, strong heat dissipation capability and strong versatility.

[0005] The technical solution for achieving the purpose of the present invention is: a compact and efficient universal coolant cooling plug-in box, comprising an upper flow channel slot, a lower flow channel slot, a left flow channel plate, a right fixing plate, a back motherboard, a plug-in box fixing plate, a handle, a guide positioning pin, an O-ring and a blind-plug fluid connector;

[0006] The upper flow channel slot, the lower flow channel slot, the left flow channel plate, the right fixing plate and the back motherboard constitute the main structure of the liquid cooling plug-in box. The front of the left flow channel plate and the right fixing plate are respectively provided with plug-in box fixing plates, and the plug-in box fixing plates are provided with handles;

[0007] The upper flow channel slot and the lower flow channel slot both use single-channel flow channels with different flow directions;

[0008] A double-channel flow channel is provided inside the left flow channel plate for connecting the flow channels between the upper flow channel slot and the lower flow channel slot, and an O-ring installation groove is provided at the flow channel interface;

[0010] The handle is used to install and remove the liquid cooling plug-in box;

[0011] Guide pins are installed on the back of the left channel plate and the right fixed plate respectively, for positioning the liquid cooling plug-in box when it is inserted into the cabinet;

[0012] A blind-plug fluid connector is installed below the guide positioning pin to connect to the liquid cooling pipeline of the liquid cooling cabinet to dissipate heat for the liquid cooling plug-in box.

[0013] Preferably, single-channel wide-section flow channels with different flow directions are designed inside the upper flow channel slot and the lower flow channel slot, and cylindrical spoiler columns with a spacing greater than a set value and evenly arranged are used inside the flow channel.

[0014] Preferably, a dual-channel flow channel is provided inside the left flow channel plate for connecting the flow channels between the upper flow channel slot and the lower flow channel slot, specifically as follows:

[0015] Flow channel openings are set on the upper and lower sides of the cabinet structure, and end face sealing is adopted between the flow channel openings and the upper flow channel slots and the lower flow channel slots.

[0016] Preferably, the lower flow channel slot is provided with two pairs of water channel interfaces and two pairs of liquid flow channels, each pair of water channel interfaces includes a liquid inlet and a liquid outlet, the two pairs of liquid flow channels are used to connect the liquid cooling plug-in box with the external liquid supply pipeline, and the liquid inlet and liquid outlet of the liquid cooling plug-in box are arranged symmetrically on the left and right to ensure that the internal spring sealing devices of the two blind plug-in fluid connectors are evenly stressed when the liquid cooling plug-in box is installed horizontally.

[0017] Preferably, the guide positioning pins are respectively installed on the upper back of the left flow channel plate and the right fixed plate, and the guide positioning pins are located at positions corresponding to the blind plug fluid connectors inside the cabinet.

[0018] Preferably, the mating surfaces of the left flow channel plate, the right fixed plate, the upper flow channel slot and the lower flow channel slot are provided with mounting stoppers and positioning pin structures for positioning during installation of guide positioning pins.

[0019] Preferably, the length of the guide locating pin is greater than the length of the blind-mate fluid connector, so that the fit between the guide locating pin and the guide sleeve precedes the fit between the blind-mate fluid connector plug and the socket, thereby enabling the blind-mate fluid connector to be accurately docked.

When the plug-in box width is 84HP, the flow resistance of the entire liquid cooling plug-in box is no more than 2 bar, and the flow rate is moderate. At this time, the heat dissipation capacity of each slot of the liquid cooling plug-in box can reach 240W, and there is no need to specially design the cooling channel of the high heat consumption module plug-in installation position. For plug-ins with different functions, only the plug-in box slots need to be adjusted accordingly, which has strong versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The upper flow channel slot 1 and the lower flow channel slot 2 are internally designed with single-channel wide-section flow channels with different flow directions;

[0036] The handle 6 is used to install and remove the liquid cooling plug-in box;

[0037] The guide positioning pins 7 are installed on the back of the left flow channel plate 3 and the right fixed plate 4 for positioning the liquid cooling plug-in box when it is inserted into the cabinet;

[0038] A blind-plug fluid connector 9 is installed below the guide positioning pin 7 for connecting to the liquid cooling pipeline of the liquid cooling cabinet to dissipate heat from the liquid cooling plug-in box.

[0039] In the present invention, the thickness of the left flow channel plate 3 and the right fixed plate 4 is small, the effective space inside the plug-in box is large, and the structure is simple, and the slide rail structure of the original air-cooled plug-in box can be directly used; the plug-in box shape meets the national military standard 6U plug-in box shape requirements, and is suitable for standard plug-in modules such as standard VPX, ASAAC, etc., and has high cabinet compatibility.

[0040] As a specific example, combining Figure 4 、 Figure 5 The upper flow channel slot 1 and the lower flow channel slot 2 are designed with single-channel wide-section flow channels with different flow directions, and the liquid flow of the liquid cooling plug-in box can be realized by cooperating with the left flow channel plate 3; the flow channel adopts cylindrical spoiler columns with large spacing and uniform arrangement, and the flow channel is not easy to be blocked.

There is no need to specially design the cooling flow channel at the installation position of the high heat consumption module plug-in. For plug-ins with different functions, only the plug-in box slot needs to be adjusted accordingly, and it has strong versatility.

[0041] As a specific example, combining Figure 1 、 Figure 3 、 Figure 6 、 Figure 7 A dual-channel flow channel is designed inside the left flow channel plate 3 to realize the series connection of the flow channels between the upper flow channel slot 1 and the lower flow channel slot 2; flow channel openings are set on the upper and lower sides of the cabinet structure, and end face sealing is adopted between the flow channel openings and the upper flow channel slot 1 and the lower flow channel slot 2.

[0046] (2) The blind-plug fluid connector has good docking performance and low difficulty in associated design: the guide positioning pins are engaged before the blind-plug fluid connector is docked, ensuring that the blind-plug fluid connector is accurately docked; the liquid inlet and outlet of the plug-in box are symmetrically arranged on both sides of the lower flow channel slot, which not only ensures that the two blind-plug fluid connectors are evenly stressed when the liquid-cooled plug-in box is installed horizontally, but also avoids the phenomenon of uneven stress on the internal spring of the connector causing jamming during docking, and also effectively reduces the design difficulty of the cabinet rotating rack water distributor used in conjunction with the liquid-cooled plug-in box;

[0047] (3) Fewer welded parts and high reliability: Only the upper flow channel slot, the lower flow channel slot and the left flow channel plate are needed to complete the liquid circulation of the liquid cooling plug-in box, avoiding the design of the flow channel inside the right fixed plate, reducing the number of welded parts and improving the reliability of the equipment; the standard O-ring sealing design is used at each flow channel interface, and the sealing method is simple and reliable;
