As shown in fig. 1, fixing portions 121 are provided at both ends of the connection pipe 120, and the fixing portions 121 at both ends of the connection pipe 120 have the same structure. Therefore, the following description will take one connection portion 132 as an example.

The first end 1211 of the fixing portion is fixedly connected to the connecting tube 120, the second end 1212 of the fixing portion extends along an axial direction (x-direction) of the connecting tube 120 in a direction away from the first end 1211 of the fixing portion, and the second end 1212 of the fixing portion is suspended. The second end 1212 of the fixing portion is provided with an inwardly extending convex wall 1213, the convex wall 1213 being snap-connected with the boss 131 in the axial direction (x-direction) of the connection tube 120.

In other embodiments, the fixing portion 121 may be disposed outside the adaptor 130, and the boss 131 may be disposed outside the connection tube 120. In the embodiment of the present application, the arrangement positions of the fixing portion 121 and the boss 131 are not further limited. The fixing portion 121 may be provided on one of the connection pipe 120 and the adapter 130, and the boss 131 may be provided on the other of the connection pipe 120 and the adapter 130.

According to the water cooling assembly connecting structure 101 provided by the embodiment of the application, the fixing part 121 is arranged on the outer side of one of the connecting pipe 120 and the adapter 130, the boss 131 matched with the fixing part 121 is arranged on the outer side of the other one of the connecting pipe 120 and the adapter 130, so that a clamping connection structure can be formed between the fixing part 121 and the boss 131, and the connecting pipe 120 and the adapter 130 are fixedly connected.

Through the fixed connection of the first end 1211 of the fixed portion and one of the connecting pipe 120 and the adaptor 130, the second end 1212 of the fixed portion is suspended, so that a plug connection structure can be formed between the connecting pipe 120 and the adaptor 130, and the assembly difficulty is reduced.

In addition, by fixedly connecting the first end 1211 of the fixing portion with one of the connection pipe 120 and the adapter 130 and the second end is snap-coupled with the boss 131, a part of the structure of the fixing portion 121 coincides with a structural portion of the connection pipe 120 or the adapter 130 in the axial direction of the connection pipe 120, so that the occupied space of the fixing portion 121 can be reduced to realize small-space assembly.

The water-cooling assembly connection structure 101 provided by the embodiment of the application can be applied to a water-cooling assembly.

As shown in fig. 2 and 3, the water cooling module 100 includes a water cooling module connection structure 101 and a liquid cooling plate 110. Wherein, two liquid cooling plates 110 are oppositely arranged at two ends of the water cooling assembly connection structure 101. The liquid cooling plate 110 is provided with a containing cavity 111 (see fig. 4), and one surface of the liquid cooling plate 110 facing the water cooling assembly connection structure 101 is provided with an opening 112, and one end of the adapter 130, which is away from the connecting pipe 120, is enclosed outside the opening 112 and is in sealing connection with the liquid cooling plate 110, so that the connecting pipe 120 is communicated with the liquid cooling plate 110. The adaptor 130 is inserted into the connection pipe 120 toward one end of the connection pipe 120 and is connected with the connection pipe 120 in a sealing manner.

According to the water cooling assembly connecting structure 101 provided by the embodiment of the application, through the arrangement of the connecting pipe 120, the size of the connecting pipe 120 can be changed by changing the length of the connecting pipe 120 so as to adapt to different distances between the two liquid cooling plates 110, so that the subsequent assembly is convenient.

In the assembly of the liquid cooling plate 110 and the water cooling module connection structure 101, the adapter 130 may be fixedly connected to the liquid cooling plate 110, and then the connection pipe 120 may be assembled to the two adapters 130. The water cooling module connection structure 101 may be assembled first, and the water cooling module connection structure 101 may be connected to the two liquid cooling plates 110.

In one possible implementation, the connection between the liquid cooling plate 110 and the adapter 130 may be achieved by welding or the like. In the embodiment of the present application, the connection manner between the liquid cooling plate 110 and the adapter 130 is not further limited.

In some embodiments, in order to further reduce the assembly space, the fixing portion 121 may be movably disposed on the outer wall of the connection pipe 120. For example, the first end 1211 of the fixing portion may be disposed on an annular base (shown in the drawings) that is sleeved on the outside of the connection pipe 120, and the base is movably disposed with the connection pipe 120 in the axial direction of the connection pipe 120. For example, the inner wall of the annular base may be provided with internal threads, and the outer wall of the connection tube 120 may be provided with external threads that mate with the internal threads. The connecting pipe 120 is connected with the annular base of the fixing part 121 in a matching way, and the base can be rotated to drive the fixing part 121 to move along the axial direction of the connecting pipe 120.

Therefore, when the connecting pipe 120 is connected with the adaptor 130, the fixing portion 121 can be moved inwards, so that the fixing portion 121 is far away from the adaptor 130, and the occupied assembly space is reduced.

In the embodiment of the present application, the structure of the fixing portion 121 is not further limited.

Fig. 4 is a schematic cross-sectional view of a water cooling assembly according to an embodiment of the present utility model.

Illustratively, as shown in FIG. 4, a receiving chamber 111 is provided within the liquid cooling plate 110. The receiving chamber 111 may be used for receiving a heat exchange medium, such as a cooling liquid or the like.

As shown in fig. 3 and 4, an opening 112 may be provided on a surface of the liquid cooling plate 110 facing the connection pipe 120, and the opening 112 may be connected to the adapter 130. By providing the accommodating chamber 111 in the liquid cooling plate 110, the heat transfer medium can be accommodated in the liquid feeding plate 110, so that the heat transfer function of the water cooling assembly 100 can be realized.

In one possible implementation, the adaptor 130 may have a hollow structure, and one end of the adaptor 130 is located outside the opening 112 and communicates with the receiving chamber 111 of the liquid cooling plate 110, and the other end communicates with the connection pipe 120, so that the liquid cooling plate 110 and the connection pipe 120 communicate. In this way, in use, a communication state is achieved between the two liquid cooling plates 110.

Illustratively, the outer diameter of the opening 112 is less than or equal to the inner diameter of the adaptor 130. So that the adapter 130 can be hermetically connected to the liquid cooling plate 110.

For example, when in use, the heat exchange medium can be input through one of the liquid cooling plates 110, and then discharged from the other liquid cooling plate 110 after passing through the connecting pipe 120, so as to play a role in heat dissipation for the electric core arranged between the liquid cooling plates 110.

In the embodiment of the present application, the shape of the opening 112 on the liquid cooling plate 110 is not limited, for example, the opening 112 may be a circular through hole, or may be a rectangular, triangular or irregular through hole. As long as it is a through hole and is less than or equal to the inner diameter of the adapter 130.

Illustratively, the material of the liquid cooling plate 110 may be aluminum. A dense oxide film can be formed on the surface of aluminum in dry air, so that aluminum is not further oxidized and can resist water. The use of the liquid cooling plate 110 made of aluminum can improve the service life of the water cooling module 100. Of course, in other embodiments, the material of the liquid cooling plate 110 may be other materials. In the embodiment of the present application, the material of the liquid cooling plate 110 is not further limited.

Fig. 5 is a schematic structural diagram of an adaptor of a water cooling assembly according to an embodiment of the present utility model. Fig. 6 is a schematic structural diagram of a connecting pipe of a water cooling assembly according to an embodiment of the present utility model.

In one possible implementation, as shown in fig. 4 and 5, the boss 131 is a tapered boss 131, wherein the large end of the tapered boss 131 faces away from the first end 1211 of the fixed portion.

By providing the boss 131 as a tapered boss 131, the second end 1212 of the fixing portion may gradually expand outwardly along the tapered outer wall 1311 of the boss 131 when the connection tube 120 and the adapter 130 are connected, until the second end 1212 of the fixing portion snaps into engagement with the boss 131 as the boss 131 moves to a side facing away from the first end 1211 of the fixing portion. Therefore, the driving force required during installation can be reduced, and the installation is convenient. In addition, since the tapered outer wall 1311 is gradually enlarged in size and gradually transitions smoothly, it is possible to avoid the second end 1212 of the fixing portion from being suddenly deformed in large size during the connection, thereby damaging the fixing portion 121.

It should be noted that, the outer diameter of the boss 131 is larger than the inner diameter of the boss wall 1213, so that the boss wall 1213 and the boss 131 can be engaged with each other.

In one possible implementation, as shown in fig. 4 and 5, the adapter 130 is provided with a connection portion 132 toward one end of the connection pipe 120. The connecting portion 132 is connected with the connecting tube 120 in a matching way, and a sealing ring 134 is sleeved on the outer wall of the connecting portion 132.

The connection portion 132 is provided on the adapter 130 so as to be connected to the connection pipe 120. By sleeving the sealing ring 134 on the outer wall of the connecting part 132, the adapter bracket and the connecting pipe 120 can be connected in a sealing manner, so that the water cooling assembly connecting structure 101 can be used normally.

In one possible implementation, the outer wall of the connection portion 132 is provided with a groove 133. The groove 133 is circumferentially disposed along the connecting portion 132, and the sealing ring 134 is located in the groove 133.

By providing the groove 133 on the outer wall of the connection part 132, it is possible to provide the sealing ring 134 with a mounting space so that the sealing ring 134 can be fixed at a specific position of the connection part 132, preventing the sealing ring 134 from being displaced during the connection of the connection pipe 120 and the adapter 130, thereby causing unsealing between the connection pipe 120 and the adapter 130.

In one possible implementation, a plurality of grooves 133 are disposed at intervals along the axial direction of the connection portion 132, and at least one seal 134 is disposed within each groove 133.

By providing a plurality of grooves 133 and a plurality of sealing rings 134, the sealing stability between the connection pipe 120 and the adapter 130 can be improved.

In an embodiment of the present application, the sealing ring 134 may be made of rubber, for example, ethylene propylene diene monomer (ethylene propylene diene monomer, EPDM). Since the rubber packing 134 has elasticity, it can be compressed when the connection pipe 120 and the adapter 130 are connected, and it is convenient for the connection pipe 120 and the adapter 130 to be connected. After the connection pipe 120 and the adapter 130 are connected, a gap between the connection pipe 120 and the adapter 130 is filled so that the connection pipe 120 and the adapter 130 are connected in a sealed manner. In addition, the processing cost of the rubber sealing ring 134 is low, so that the cost of the water cooling assembly connecting structure 101 and the water cooling assembly 100 can be reduced.

It should be noted that, in some embodiments, the connection portion may be disposed on the connection pipe 120. In the embodiment of the present application, this will not be further described.

The fixing portion 121 has elasticity, and the second end 1212 of the fixing portion may move along the radial direction of the connection tube 120 with respect to the outer wall of the connection tube 120.

For example, as shown in fig. 5, the fixing portion 121 may have a U-shaped structure in which an opening of the U-shaped structure faces the outer wall of the connection pipe 120. A connecting arm 1215 is provided between the first end 1211 and the second end 1212 of the fixed portion, wherein a gap is provided between the connecting arm 1215 and the connecting tube 120. The second end 1212 of the fixing portion extends beyond the connecting tube 120 in the axial direction of the connecting tube 120, so that the second end 1212 of the fixing portion can be suspended. Thereby allowing the second end 1212 of the fixing portion to move in the radial direction of the connection pipe 120 with respect to the first end 1211 of the fixing portion.

It should be noted that, in the embodiment of the present application, the number of the fixing portions 121 may be one, two, three, four, five or more, and in the embodiment of the present application, the number of the fixing portions 121 is not limited.

By setting the number of the fixing portions 121 to be plural, connection stability between the connection pipe 120 and the adapter 130 can be improved, and restraining force between the connection pipe 120 and the adapter 130 can be distributed at plural positions, and thus the service life of the fixing portions 121 can be prolonged.

In one possible implementation, the number of the fixing portions 121 is plural, wherein the plurality of fixing portions 121 are symmetrically distributed in the circumferential direction of the connection pipe 120.

Illustratively, the number of the fixing portions 121 is two, and the two fixing portions 121 are symmetrically disposed along the circumferential direction of the connection pipe 120.

By symmetrically disposing the plurality of fixing portions 121 on the outer side of the connection pipe 120, the restraining force between the connection pipe 120 and the adapter 130 can be uniformly distributed in the circumferential direction of the connection pipe 120, the moment between the connection pipe 120 and the adapter 130 can be reduced, and the connection stability of the connection pipe 120 and the adapter 130 can be improved.

In one possible implementation, in the axial direction of the connection pipe 120, a surface of the protruding wall 1213 facing away from the first end 1211 of the fixing portion is provided with an inclined surface 1214, and the inclined direction of the inclined surface 1214 is the same as the inclined direction of the tapered outer wall 1311 of the tapered boss 131.

By providing the inclined surface 1214 on the side of the protruding wall 1213 facing away from the first end 1211 of the fixing portion, the inclined surface 1214 is inclined in the same direction as the tapered outer wall 1311 of the tapered boss 131. In this way, in the process of connecting the connecting pipe 120 and the adaptor 130, as shown in fig. 3, the inclined surface 1214 and the tapered outer wall 1311 can be cooperatively connected, and since the transition between the inclined surface 1214 and the tapered outer wall 1311 is smoother, the friction between the convex wall 1213 and the boss 131 can be reduced, thereby reducing the assembly force and facilitating the installation. Wear of the convex wall 1213 and the boss 131 can be reduced.

In the embodiment of the present application, the size of the inclined surface 1214 is not further limited. In some embodiments, the inclined surface 1214 may not be provided.

In one possible implementation, the fixing portion 121 and the connection tube 120 may be fixedly connected by welding, bonding, or integrally forming.
