Description

Technical Field

[0001] This invention relates to the field of fluid connection technology, and in particular to a split-type right-angle fluid adapter. Background Technology

[0002] With the increasing power of equipment such as radar, power supplies, and high-performance computing chips, heat dissipation is gradually shifting from air cooling to liquid cooling. Liquid cooling pipes and cold plates are typically connected and disconnected using fluid connectors or fluid adapters. Military products are increasingly moving towards integration and miniaturization, compressing the axial and radial installation space within equipment to the millimeter level. Traditional integrated right-angle fluid adapters, snap-fit ​​connectors, and push-pull connectors, due to their complex structures and large installation space requirements, can no longer meet the installation and usage requirements in certain special situations.

[0003] Currently, commonly used self-locking right-angle liquid-cooled adapters mainly include snap-fit ​​connectors, push-pull connectors, and integrated right-angle liquid-cooled adapters. Among them, snap-fit ​​connectors and push-pull fluid connectors have relatively complex structures, with the socket connector alone containing more than ten parts. Moreover, the axial installation space is relatively large after the plug and socket are mated, and the insertion and extraction forces are relatively large during disassembly and assembly. When the integrated right-angle adapter is installed by thread, the adapter needs to rotate axially, which is suitable for occasions with sufficient installation space. However, the right-angle connector cannot be rotated axially after installation. In addition, none of the above three connector structures can locally adjust the system flow resistance during use.

[0004] To address the aforementioned issues, a split-type elbow fluid connector disclosed in publication number CN216555908U achieves quick connection through a split design of the elbow connector and the mating connector. However, this structure still uses a snap-locking mechanism, resulting in a large axial installation space and no adjustable flow resistance. Another example is a highly reliable, leak-free rotary fluid connector disclosed in publication number CN119508605A, which can achieve 360° rotation. However, its structure is complex, containing multiple parts such as bearings and positioning nuts, resulting in high costs. It also lacks flow resistance adjustment functionality. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings mentioned above by providing a split right-angle fluid adapter that offers advantages such as simple structure, adjustable installation angle, good sealing performance, small installation space, and adjustable local flow resistance.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a split-type right-angle fluid adapter, comprising: The valve body has a flow channel and a mounting hole inside, and the flow channel and the mounting hole are perpendicular to each other and are interconnected. The valve core is rotatably inserted into the mounting hole of the loop valve body. The valve core has a flow channel inside and an oblong hole communicating with the flow channel is opened on the surface of the valve core. The oblong hole is arranged opposite to the flow channel on the loop valve body. The first sealing ring is disposed on the outer wall of the valve core to achieve a static seal between the valve core and the external cold plate. The second sealing ring is disposed between the valve body and the valve core to achieve dynamic sealing between the valve body and the valve core. A hose fixing component is provided on the surface at the connection between the slip-on valve body and the external hose to achieve the connection and fixation between the slip-on valve body and the external hose.

[0007] Furthermore, one end of the slip-on valve body is a barbed structure, and the flow channel is set on the barbed structure to achieve an interference fit with the external hose. The other end of the slip-on valve body is a cube structure, and the mounting hole is opened on the cube structure to achieve the installation of the valve core.

[0008] Furthermore, the inner surface of the valve body located at the mounting hole is provided with a first annular groove, which corresponds to the second sealing ring.

[0009] Furthermore, the valve core has a second annular groove on its surface inside the mounting hole of the valve body, which corresponds to the second sealing ring. The valve core also has a third annular groove on its surface outside the valve body, which corresponds to the first sealing ring.

[0010] Furthermore, the valve core has an external thread structure on one end surface located outside the valve body, and the external thread structure corresponds to the mounting screw hole on the cold plate. The bottom of the other end of the valve core also has an internal hexagonal groove.

[0011] Furthermore, the number of the four waist-shaped holes is four, which are evenly distributed around the circumference of the valve core, and the shaft diameter at the location of the waist-shaped holes is smaller than the inner diameter of the loop valve body.

[0012] Furthermore, the hose fixing component is a ring-shaped component that is fixed by ring compression.

[0013] The beneficial effects of this invention are reflected in: 1. Through the split design, while ensuring liquid continuity, it features a simple product structure, small installation space, and adjustable valve body angle; 2. Through multi-layer sealing design, the reliability of the product is significantly improved, avoiding the risk of failure caused by leakage of the liquid cooling system; 3. Through the valve core local flow resistance adjustment design, the product can solve the problem of the inability to locally adjust the flow resistance during the use of right-angle connectors by rotating the valve core.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-6 This invention discloses a split-type right-angle fluid adapter, comprising: The valve body 1 has a barbed structure at one end to achieve an interference fit with the external hose, and a cube structure at the other end to achieve the installation of the valve core 2. One end of the barbed structure has a flow channel inside, while one end of the square structure has a through mounting hole, and the flow channel and the mounting hole are perpendicular to each other and are connected. Meanwhile, the inner surface of the valve body 1 located at the mounting hole is provided with a first annular groove 11.

[0018] Valve core 2 is rotatably inserted into the mounting hole of the loop valve body 1. A flow channel is provided inside the valve core 2. An oblong hole 21 communicating with the flow channel is opened on the surface of the valve core 2. The oblong hole 21 is arranged opposite to the flow channel on the loop valve body 1. There are four waist-shaped holes 21. The four waist-shaped holes 21 are evenly distributed around the circumference of the valve core 2. The diameter of the shaft where the waist-shaped holes 21 are located is smaller than the inner diameter of the loop valve body 1. The waist-shaped holes 21 connect the flow channels on the loop valve body 1 and the valve core 2, so that the assembled whole is a complete passage that allows fluid to pass through. The valve core 2 is provided with a second annular groove 22 on the surface of the valve body 1 mounting hole. When assembled, the second annular groove 22 corresponds to the first annular groove 11, and a second sealing ring 4 is installed between the second annular groove 22 and the first annular groove 11. The dynamic seal between the valve body 1 and the valve core 2 is achieved through the second sealing ring 4. The valve core 2 has an external thread structure on one end surface outside the sleeve valve body 1, and the external thread structure corresponds to the mounting screw hole on the cold plate, thereby realizing the connection between the valve core 2 and the cold plate. At the same time, a third annular groove 23 is also opened on one end surface of the external screw structure of the valve core 2, and a first sealing ring 3 is installed at the third annular groove 23, and the static seal between the valve core 2 and the external cold plate is realized through the first sealing ring 3. The other end of the valve core 2 is also provided with an internal hexagonal groove 24, which is H6 in size, to facilitate installation and adjustment using a standard internal hexagonal wrench. At the same time, a wire hole is also provided at this end. It should be noted that both the valve body 1 and the valve core 2 are made of 304 stainless steel, which has good corrosion resistance and mechanical strength.

[0019] Hose fixing component 5 is provided on the surface of the connection between the loose valve body 1 and the external hose to realize the connection and fixation between the loose valve body 1 and the external hose. Among them, the hose fixing component 5 is a ring-shaped component that is fixed by ring compression; Furthermore, the hose fixing component 5 can also be a clamping clamp.

[0020] With the above structural design, during use, one end is connected to the hose blank through the barbed structure of the loose valve body 1, and the other end is connected to the cold plate flow channel through the tail thread of the valve core 2. During installation, an Allen wrench is inserted into the Allen groove 24 at the head of the valve core 2 and rotated clockwise along the axial direction to screw it into the cold plate mounting hole until the end face of the hollow cube coincides with the connector mounting surface. At this time, the sealing ring achieves double sealing between the cold plate and the valve core 2, and bidirectional sealing between the valve core 2 and the loose valve body 1. At the same time, by rotating the valve core 2, the projected area of ​​the waist-shaped hole 21 of the valve core and the axial hole of the loose valve body 1 can be adjusted, thereby adjusting the local flow resistance.

[0021] The main innovation of this invention is as follows: 1. Split-type design of right-angle fluid adapter: The product innovatively designs the traditional one-piece right-angle adapter into a separate structure of loose valve body 1 and valve core 2. During installation, the valve core 2 is connected to the cold plate through the external thread at the tail. During installation, the loose valve body 1 can rotate with the valve core 2. While ensuring liquid continuity, it has the characteristics of simple product structure, small installation space, and adjustable angle of loose valve body 1.

[0022] 2. Multi-layer sealing design of right-angle fluid adapter: The product features four annular grooves on the valve core 2 and the looper valve body 1 to achieve sealing between the valve core 2 and the cold plate, as well as between the valve core 2 and the looper valve body 1. The multi-layer sealing ring design effectively avoids the risk of liquid leakage.

[0023] 3. Valve core local flow resistance adjustment design: Four oblong holes 21 are provided at the valve core 2. During the use of the product, by rotating the valve core 2, the projected area of ​​the oblong holes 21 of the valve core and the axial hole of the valve body 1 can be adjusted (the larger the projected area, the smaller the flow resistance), thereby adjusting the local flow resistance.

[0024] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
