FIG. 2 shows a schematic plan view of a blind insertion manifold system 100 according to an embodiment of the present invention. As shown in FIG. 2, the blind insertion manifold system 100 includes:

Main pipeline 110;

Multiple pairs of elastic branch pipes, one end of each elastic branch pipe 120 in the multiple pairs of elastic branch pipes communicates with the main pipeline 110;

Multiple pairs of pipe joints, each pipe joint 130 in the multiple pairs of pipe joints corresponds to each of the elastic branch pipes 120, each of the pipe joints 130 includes a first end and a second end, each of the pipe joints The first end of 130 communicates with the other end of each elastic branch pipe 120, and the second end of the first pipe joint and the second pipe joint in each pair of pipe joints 130 can be inserted into the slideway along the cabinet 300. The inlet 210 and the outlet 220 on the single board 200 are connected, so that the fluid circulates in the blind plug manifold system 100 to provide heat dissipation for the single board 200; and

The limiting component 140 is fixedly connected with the cabinet 300 and is used to limit the moving distance of each pipe joint 130 along the insertion and removal direction of the single board 200 .

Specifically, the blind insertion manifold system can be applied in a liquid cooling system. For example, power units such as water pumps in a liquid cooling system push fluid into each branch circuit through the main pipe in the blind insertion manifold system. Each branch circuit includes elastic branch pipes and pipe joints. Each single board needs to be connected with two Only when the branches are connected can the fluid circulate in the blind insertion manifold system. The fluid can enter through the inlet on the board, flow out from the outlet on the board, and then drain through the branch in the blind insertion manifold system. to the cooling unit for cooling. The limit component fixes each branch on the cabinet. When the board is connected to the branch in the blind-mating manifold system along the slideway on the cabinet, it can limit the movement of each branch in the direction of single board insertion and removal. distance.

In order to solve the problem that each slot affects each other in the blind insertion manifold system, when multiple boards are installed, the boards inserted successively affect each other, and the problem of unreliable connection is prone to occur. Elastic branch pipes are used between pipe joints, which can reduce the impact on other branches when the board is inserted. This can solve the problem of unreliable connection between the pipe joints on the single board and the pipe joints in the manifold system due to the deformation of the elastic hose when the board is inserted.

The elastic branch pipe refers to the pipeline with elasticity. The elastic branch pipe used in the present invention mainly utilizes the buffering effect of the elastic branch pipe. Since the blind insertion manifold system is installed in the cabinet through the limit assembly, when the single board is inserted, the elastic branch pipe is Connected with the main pipe of rigid material, the elastic branch pipe will buffer the force when the veneer is inserted, thereby reducing the impact of the force on other branches. For example, it could be the radial tolerance where the branch connects to the main pipe.

It should be understood that the elastic branch pipe may be a whole piece, or may be formed by splicing a plurality of pieces. The material of the elastic branch pipe can be metal, non-metal, or other combinations, such as rubber, as long as the elastic pipe is within the scope of the technical solution of the present invention.

Since the branch pipes are made of elastic materials, they are easy to deform. On the one hand, the limit component can be used to limit the position of each branch in the vertical direction, and also to limit the distance in the direction of single board insertion and insertion.

The pipe joint can usually include welding type, ferrule type, flared type and other types, and is a connecting piece used to connect the elastic branch pipe and the veneer. Optionally, the inlet and outlet of the veneer are also respectively provided with pipe joints, and the pipe joints in the blind insertion manifold system and the pipe joints on the veneer are male and female joints that cooperate with each other, that is, The pipe joints in the blind insertion manifold system are male joints, the pipe joints in the blind insertion manifold system are female joints, or the pipe joints on the board are female joints, and the pipe joints in the blind insertion manifold system are male joints, which are not limited by the present invention.

It should also be understood that multiple pairs of pipe joints in the embodiments of the present invention may be respectively connected to the inlet and outlet on the single board, that is, each pair of pipe joints includes a first pipe joint connected to the inlet on the single board, and a first pipe joint connected to the single board. The second pipe joint connected to the outlet on the board, for the convenience of description, the present invention is only described with a pair of pipe joints, but the present invention is not limited thereto.

Optionally, the limiting component is arranged at the groove of each pipe joint, the width of the groove in the insertion direction of the single board is greater than the thickness of the limiting component, and the limiting component is When the single board is inserted, the limiting component is against the first side of the groove; when the single board is pulled out, the limiting component is against the first side of the concave A second side of the groove, wherein the first side of the groove is adjacent to the second end of each fitting and the second side of the groove is adjacent to the first end of each fitting.

Specifically, the pipe joint is usually a stepped cylindrical shape, and a groove can be provided on a certain section of the cylindrical surface of the pipe joint. The two parts are respectively fixed on the cabinet at the annular groove, and after the blind insertion manifold system is installed, the two symmetrical parts are connected by a connection such as a hinge. The width of the groove in the insertion direction of the single board can be greater than the thickness of the first limiting component, for example: the width of the groove can be 6mm, the thickness of the limiting component can be 5mm, the limiting component There is a 1mm gap with this groove to absorb the tolerance in the insertion and removal direction of the single board. The size of the gap is related to the moving distance when different boards are inserted and removed, and can be determined according to specific designs. For example, it may be the rebound force of the single board, or it may be the distance between the abutting position of the single board when inserted into the blind insertion manifold system and the pipe joint.

It should be understood that the shape of the groove is not limited, as long as the position of the limiting component can be limited. Preferably, the groove is an annular groove.

The grooves can be respectively arranged close to the second ends of the pipe joints, so as to reduce the bearing force of the limiting assembly. Specifically, due to the difference in gravity between the elastic branch pipe and the pipe joint, the two ends of the pipe joint and the elastic branch pipe are unbalanced, and the end of the pipe joint will sink. The farther away, the smaller the force that the limit component bears.

Optionally, the limiting component is a limiting plate with a plurality of through holes, and the diameters of the through holes on the limiting plate are the same and larger than the cross-sectional diameter of the annular groove.

The limiting plate can be a metal plate with multiple holes, and the metal plate can be a copper plate, an aluminum alloy plate or other combinations. It should be understood that the through hole may be a square hole, a round hole or other irregularly shaped holes, which is not limited in the present invention. When the through hole is a round hole, the diameter of the round hole can be slightly larger than or equal to the cross-sectional diameter of the groove, but smaller than the diameters on both sides of the groove; when the through hole is a square hole, the diagonal of the square hole Can be slightly larger than or equal to the cross-sectional diameter of the groove, but smaller than the diameters on both sides of the groove.

Optionally, the limiting plate can also be arranged between a stepped end surface of the pipe joint and the collar fixed on the pipe joint. For example, the pipe joint is divided into two steps, the diameter of the large end is 40mm, and the diameter of the small end is 30mm. If the through hole diameter of the limiting plate is 30.5mm, the limiting plate can be passed through the small end of the pipe joint. It is stuck on the end face whose diameter of the big head is larger than the diameter of the through hole, and a collar is put on the diameter of the small head. A certain gap can be left between the collar and the limiting plate, and the first limiting component is screwed. locked.

Optionally, as shown in FIG. 3 , the blind insertion manifold system 100 further includes: a fixed installation assembly 150 and a plurality of elastic assemblies, the fixed installation assembly 150 is fixedly connected to the cabinet 300, and each of the plurality of elastic assemblies One end of each elastic component 160 is against the fixed installation component 150 , and the other end of each elastic component 160 is against the corresponding pipe joint 130 , and each elastic component 160 is in a compressed state to provide a horizontal force for the corresponding pipe joint 130 .

Specifically, since the hole diameter of the limiting plate is larger than the cross-sectional diameter of the annular groove, in order to keep the axis of a branch pipe in a horizontal state, the elastic force of the elastic component can be used to provide a pre-tightening force for the pipe joint. The elastic assembly can use an end face or a stepped surface of the fixed installation assembly and the pipe joint to make the elastic assembly in a compressed state, and any method that can provide pre-tightening force for the pipe joint is within the scope of the technical solution of the present invention, and the present invention is not limited . The compressed length of the elastic component is related to the force required to support the pipe joint. The elastic component can be relatively short in a fully compressed state, or relatively long in a partially compressed state.

Similar to the limiting component, the fixed installation component may be a fixed installation plate with a plurality of through holes, and the diameters of the plurality of through holes on the fixed installation plate are the same. Similarly, the fixed mounting plate can be a metal plate with a plurality of holes, and the metal plate can be a copper plate, an aluminum alloy plate or other combinations. It should be understood that the through holes on the fixed mounting plate may be square holes, round holes or holes with other irregular shapes, which is not limited in the present invention.

Optionally, a fixed installation plate can also be arranged between a stepped end surface of the pipe joint and the collar fixed on the pipe joint, and the installation method of the fixed installation plate can refer to the installation method of the limit plate in the above-mentioned embodiment , which will not be repeated here. One end of each elastic component can abut against the fixed installation component, and the other end of the elastic component can abut against the stepped surface of the corresponding pipe joint, and the diameter of the stepped surface of each pipe joint is larger than that of the first end of the corresponding pipe joint end face diameter.

For example, if the pipe joint is of two-stage type, the diameter of the end surface of the first end is 20mm, and the diameter of the end surface of the second end is 30mm. The diameter of the cross section at the groove is 25mm, the diameter of the elastic component is 22mm, it passes through the first end of the pipe joint, and one end abuts against the stepped surface on the pipe joint, the hole diameter of the fixed mounting plate is 21mm, and it can also pass through the pipe The first end of the joint abuts against the other end of the elastic component, so that the elastic component can be in a compressed state to provide a horizontal force for the pipe joint, so that the axis of the pipe joint is in a horizontal state.

Optionally, as shown in FIG. 3 , the fixed installation assembly may be arranged at the rigid connection of each elastic branch pipe, one end of each elastic assembly abuts against the fixed installation assembly, and the other end of each elastic assembly abuts against the fixed installation assembly. against the end face of the first end of the corresponding fitting.

Rigid connection can refer to a pipe connection method in which the hose is heated by a flame so that the hot melt adhesive on the inner surface of the hose is bonded to the outer surface of the pipe, and the hose is cooled and solidified to form a constant tight force. The limiting assembly can be arranged at the rigid connection of the hose, or at the end of the pipe quick connector connected to the rigid connection, which is not limited by the present invention.

Fig. 4 shows a specific possible implementation manner provided by the embodiment of the present invention. As shown in FIG. 4, the blind insertion manifold system 600 includes:

main pipe 610;

Elastic branch pipe 620, one end of the elastic branch pipe communicates with the main pipeline;

Pipe joint 630, the first end of the pipe joint is connected with the other end of the elastic branch pipe one by one, and the second end of the pipe joint is used to communicate with the pipe joint on the single board that can be plugged along the slideway on the cabinet;

The fixed installation assembly 650 is arranged at the rigid connection of the elastic branch pipe, and includes a first part arranged parallel to the limiting plate and a second part and a third part for connecting the first part to the limiting plate. The second part and the third part are set to be symmetrical to each other;

The elastic component 660 is disposed between the fixed installation component and the end surface of each pipe joint, and the elastic component is in a compressed state so that the axis of each pipe joint is in a horizontal state.

As shown in Figure 4, the fixed installation components required by each elastic branch pipe are independent of each other, and the fixed installation components can be fixed by riveting or welding screw nuts, etc. The disassembly method is not limited in the present invention.

Optionally, the elastic component may be a spring, a shrapnel or other specifically elastic components.

Optionally, the pipe joint can adopt a quick connector with or without float. For example, when the veneer is inserted, it needs to move a distance of 3mm toward the main pipe, and a quick joint with a floating amount of 2mm can be used, and the remaining 1mm can be guaranteed by the gap between the limit plate and the annular groove, that is, it can be compressed The elastic branch pipe is 1mm; a quick joint with a floating amount of 3mm can also be used, and there may be no gap between the limit plate and the annular groove; a quick joint without a floating amount can also be used, and the 3mm is completely composed of the limit plate and the annular groove. Clearance between grooves is guaranteed.

Usually, the floating amount of the quick connector is directly proportional to the cost, that is, the larger the floating amount, the higher the cost. For example, if the floating amount of the quick connector is 2mm, the price is 10 yuan; and when the floating amount of the quick connector is 4mm, the price may be 30 yuan. Therefore, in order to be able to use a low-cost quick connector, the gap between the elastic hose and the limiting plate and the annular groove can be used to absorb the tolerance of the single board in the insertion and withdrawal direction.
