Description

Technical field:

[0001] The invention belongs to the technical field of marine cooling and relates to a blind-plug parallel segmented liquid cooling distributor. Background technology:

[0002] As the integration and complexity of marine electronic equipment become higher and higher, and liquid cooling technology has the advantages of good heat dissipation, low noise and less dust, it can better meet the heat dissipation requirements of high-power electronic equipment. Therefore, liquid cooling cabinets are becoming more and more widely used in marine electronic equipment systems.

[0003] At present, the liquid cooling system of marine liquid cooling cabinets consists of liquid cooling distributors, fluid connectors and some hoses. The liquid cooling distributor is generally installed at the rear of the cabinet and is large in size. It mainly plays the function of distributing coolant in the system and plays a key role. However, in actual use, especially blind plug-in liquid cooling cabinets, there are the following problems:

[0004] First, for marine electronic equipment, the liquid cooling distributor cannot be replaced and repaired because the operation space is small and the operation can only be performed on the front of the cabinet. Second, for blind-plug connectors, it is difficult to quickly and accurately blind-plug the liquid cooling distributor and the liquid cooling chassis during use.

[0005] How to improve the maintainability of blind-plug liquid-cooled cabinet distributors and realize the rapid plug-in and unplugging of liquid-cooled distributors and liquid-cooled chassis while ensuring effective heat dissipation of marine electronic equipment has become a bottleneck in the promotion and use of blind-plug liquid-cooled cabinets. Summary of the invention:

[0006] The technical problem to be solved by the present invention is to provide a blind-plug parallel segmented liquid-cooled distributor, which solves the problem that the distributor of the liquid-cooled cabinet of marine electronic equipment cannot be replaced and repaired, improves the installation accuracy of the blind-plug connectors between each sub-distributor and the liquid-cooled chassis, and solves the problem of fast and accurate plugging and unplugging of the blind-plug connectors between the distributor and the liquid-cooled chassis.

[0007] The technical solution of the present invention is to provide a blind-plug parallel segmented liquid-cooled distributor, including multiple sub-distributors, with slide rails symmetrically provided on both sides of the sub-distributor, and a liquid-cooled chassis that can be pushed and pulled forward and backward is provided on the slide rails, and an electrical connector seat, a fluid connector seat, a positioning pin seat and a built-in flow channel are also provided on the sub-distributor; an electrical connector head, a fluid connector head and a positioning pin are correspondingly installed on the liquid-cooled chassis; when the liquid-cooled chassis is pushed into the rear side of the slide rail, the electrical connector head, the fluid connector head and the positioning pin on the liquid-cooled chassis are respectively connected to the electrical connector seat, the fluid connector seat and the positioning pin seat on the corresponding sub-distributor in a blind-plug form; multiple sub-distributors are arranged in parallel, and each sub-distributor is connected by a hose to form a closed liquid cooling circuit.

[0008] Preferably, the fluid connector seat is connected to the sub-distributor via a connector mounting seat.

[0009] Preferably, the hose is communicated with a built-in flow channel of the corresponding sub-distributor.

[0010] Preferably, the sub-distributors are connected in parallel in a segmented manner.

[0011] Preferably, the slide rail is provided with a slide rail bar, which is made of polytetrafluoroethylene. The slide rail bar material is required to be wear-resistant and have a small surface friction coefficient. Each sub-distributor slide rail is installed with a slide rail bar, which is made of polytetrafluoroethylene and other materials. This material is wear-resistant and has a small surface friction coefficient, which reduces the pulling resistance of the liquid cooling chassis to achieve a quick plug-in and pull-out effect of the chassis.

[0012] Preferably, the sub-distributor and the slide rail are formed by one-piece molding or welding, which improves the mutual installation position accuracy of the slide rail, connector mounting seat and positioning pin mounting hole on the sub-distributor, and facilitates chassis installation. Each sub-distributor and its slide rail are formed by one-piece molding or welding, which improves the installation accuracy of the blind plug connector between each sub-distributor and the liquid-cooled chassis, and realizes the fast and accurate plug-in and pull-out effect between the distributor and the liquid-cooled chassis.

[0013] Preferably, the built-in flow channel is formed by friction stir welding or internal wedge forming pipeline technology.

[0014] Preferably, the sub-distributors are mounted on the cabinet by screws and can be removed from the cabinet individually. Each sub-distributor has a similar structure and a small size, is connected to the cabinet by screws, etc., and can be disassembled and repaired individually from the front of the cabinet, thereby improving the maintainability of the cabinet.

[0015] Preferably, the hose is composed of a Teflon hose and a stainless steel flange end face. Each sub-distributor is connected in parallel, and the connecting pipeline uses a Teflon hose, which can also be disassembled and repaired on the front of the cabinet, further improving the maintainability of the cabinet. The Teflon hose has a certain elastic property of its material. After the sub-distributors are connected, a certain amount of displacement is allowed between the sub-distributors to ensure that the sealing end face does not deviate or leak, so as to meet the use of marine electronic equipment under vibration.

[0016] Working principle: The blind-plug parallel segmented liquid cooling distributor consists of multiple sub-distributors and hoses. Each sub-distributor has a similar structure and is small in size. It is connected to the cabinet by screws or other means. The sub-distributors are interconnected by hoses to form a closed-loop liquid cooling circulation circuit. Each sub-distributor is equipped with a slide rail and is processed by one-piece molding or welding technology, which improves the installation accuracy of the blind plug connector between each sub-distributor and the liquid cooling chassis. The slide rail is installed on the slide rail to reduce the pulling resistance of the liquid cooling chassis, thereby achieving the effect of quick plugging and unplugging of the chassis.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) The maintainability of the liquid cooling distributor is greatly improved compared with the previous blind plug-in liquid cooling cabinet for ships, and a new method is provided for the design of liquid cooling distributor for blind plug-in liquid cooling cabinet;

[0019] (2) While enhancing the maintainability of the cabinet, the slide rails and hoses have been improved to achieve convenient use of the liquid-cooled chassis while meeting the requirements for use in vibration conditions of marine electronic equipment. Description of the drawings:

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] The present invention designs a blind-plug parallel segmented liquid cooling distributor, such as Figure 1-6As shown: it includes multiple sub-distributors 1, and the two sides of the sub-distributors 1 are symmetrically provided with slide rails, and the slide rails are provided with a liquid cooling chassis 9 that can be pushed and pulled forward and backward. The sub-distributors 1 are also provided with an electric connector seat 6, a fluid connector seat 7, a positioning pin seat 8 and a built-in flow channel 5; the liquid cooling chassis 9 is correspondingly installed with an electric connector head 10, a fluid connector head 11, and a positioning pin 12; when the liquid cooling chassis 9 is pushed into the rear side of the slide rail, the electric connector head 10, the fluid connector head 11, and the positioning pin 12 on the liquid cooling chassis 9 are respectively connected with the electric connector seat 6, the fluid connector seat 7, and the positioning pin seat 8 on the corresponding sub-distributor 1 in a blind plugging manner; multiple sub-distributors 1 are arranged in parallel, and each sub-distributor 1 is connected by a hose 2 to form a closed liquid cooling circuit. It not only improves the maintainability of the blind plug liquid cooling cabinet distributor, but also realizes the quick plug-in and pull-out effect of the liquid cooling chassis.

[0028] In this embodiment, the fluid connector seat 7 is connected to the sub-distributor 1 through the connector mounting seat 4. The hose 2 is communicated with the built-in flow channel 5 of the corresponding sub-distributor 1.

[0029] like Figure 4 In this embodiment, the built-in flow channel is processed by a stir friction welding process.

[0030] like Figure 3 As shown, in this embodiment, a slide rail 3 is provided on the slide rail, and the slide rail 3 is made of polytetrafluoroethylene, and each sub-distributor 1 and the slide rail are made of an integrated molding process. This improves the mutual installation position accuracy of the slide rail 3, the connector mounting seat 4 and the positioning pin mounting hole on the sub-distributor 1, and facilitates the subsequent installation of the liquid cooling chassis 9.

[0031] like Figure 5 As shown, the hose 2 consists of two parts: a Teflon hose 13 and a stainless steel flange end face 14. The Teflon hose 13 has certain elastic properties due to its material. After the sub-distributors 1 are connected, a certain amount of displacement is allowed between the sub-distributors 1, which can meet the requirements of use in an environment with vibration.

[0032] In this embodiment, the sub-distributors 1 have similar or identical structures, the fluid interface positions on each sub-distributor 1 are the same, and the electrical connector interface positions are close (can be adjusted appropriately) to facilitate the processing of the sub-distributors 1 and the subsequent pushing and pulling of the liquid cooling chassis 9.

[0033] like Figure 4 , 5 As shown, the sub-distributor 1 has a threaded hole at the bottom, and is installed on the cabinet by screws. The sub-distributor 1 is small in size and can be disassembled and repaired from the cabinet alone. The hose 2 can also be easily disassembled and repaired from the cabinet alone.

[0034] The blind-plug parallel liquid-cooled distributor of the present invention introduces the cooling medium of the external coolant circulation system into each sub-distributor 1 through the hose 2, and then distributes the coolant to each liquid-cooled chassis 9 through the built-in flow channel 5 and the fluid connector. After the liquid-cooling medium exchanges heat with the components in the liquid-cooled chassis 9, it flows back to the circuit of each sub-distributor 1 through the fluid connector and the built-in flow channel 5, and finally flows back to the external coolant circulation system through the hose 2. This cycle is repeated to achieve the heat dissipation effect of electronic devices.

[0035] The present invention improves the installation accuracy of blind-plug connectors between each sub-distributor and a liquid-cooling chassis; a slide rail is installed on the slide rail to reduce the pulling resistance of the liquid-cooling chassis, thereby achieving a quick plug-in and pull-out effect of the chassis; and compared with the previous marine blind-plug liquid-cooling cabinet, the maintainability of the liquid-cooling distributor is greatly improved, while meeting the use requirements of marine electronic equipment under vibration conditions.

[0036] The above is only an explanation of the preferred embodiments of the present invention, which should not be construed as a limitation on the claims. Any equivalent process changes made using the present invention specification are included in the patent protection scope of the present invention.
