As shown in connection with fig. 2 and 3, in some embodiments, the second sidewall 212 is provided with at least two claws 214 at intervals along the circumferential direction, and the claws 214 are used to clamp the connection portion 110 in the seal groove 210. Specifically, the claw 214 may be integrally formed with the second side wall 212, the claw 214 is attached to the connecting portion 110 by riveting, and under the action of the pressing force of the claw 214, the connecting portion 110 presses down the sealing member 300 through the pressing surface 1121, the sealing member 300 deforms under the pressing action of the connecting portion 110, so that the sealing between the water tank 100 and the heat dissipating motherboard 200 is achieved, and the structure is simple and reasonable.

Referring to fig. 2, in some embodiments, the connecting portion 110 includes a convex step 112 and a first rib 113 and a second rib 114 protruding from the same side surface of the convex step 112, where the first rib 113 and the second rib 114 are spaced apart from each other to form a mounting groove 210, the first rib 113 is circumferentially disposed on an inner side of the connecting portion 110, and the second rib 114 is circumferentially disposed on an outer side of the connecting portion 110. Specifically, the inner side of the connecting portion 110 is a side close to the first sidewall 211, and thus the outer side of the connecting portion 110 is a side close to the second sidewall 212. The protruding directions of the first ribs 113 and the second ribs 114 are perpendicular to the inner surface of the convex step 112, that is, the pressing surface 1121, and the perpendicular arrangement can enable the first ribs 113 and the second ribs 114 to be pressed against the bottom wall 213 in the same vertical direction, so that the pressing surface 1121 is favorable for uniformly bearing force in the process of compressing the sealing element 300, consistency of compression amount of the sealing element 300 is ensured, and sealing performance of the sealing assembly 20 is enhanced.

Referring to fig. 2, in some embodiments, the first side wall 211 is attached to the first rib 113, the second side wall 212 is attached to the second rib 114, the ends of the first rib 113 and the second rib 114 away from the step 112 are both abutted against the bottom wall 213, and the sealing element 300 installed between the first rib 113 and the second rib 114 protrudes from the first rib 113 and the second rib 114 in a natural state.

In addition, the width between the first ribs 113 and the second ribs 114 is consistent with the width between the first side wall 211 and the second side wall 212, which is favorable for the connection portion 110 to be just clamped into the sealing groove 210, and no larger shaking occurs, so that the sealing performance of the sealing assembly 20 is enhanced. It is understood that the seal 300 naturally protrudes from the first ribs 113 and the second ribs 114, which means that a certain compression margin should exist in the seal 300 before the seal 300 is compressed by the connection portion 110, and further, the compression margin may be determined according to a series of sealing performance indexes, and the selection corresponding to the seal may be the selection of the thickness, the elastic coefficient, and the like of the seal.

As shown in connection with fig. 2, in some embodiments, the protruding lengths of the first beads 113 and the second beads 114 are identical. It can be understood that the protruding length refers to the protruding length of the first rib 113 and the second rib 114 relative to the pressing surface 1121 in the vertical direction in the drawing, and by the arrangement of the protruding lengths of the first rib 113 and the second rib 114 being consistent, the connection portion 110 is beneficial to the process of reversely pressing the sealing element 300 down on the vertical bottom wall 213, and the first rib 113 and the second rib 114 can simultaneously press the bottom wall 213, so that the compression amount of the sealing element 300 can be kept the same in the circumferential direction, thereby avoiding the situation that the compression amount of the sealing element 300 is too large or too small, and enhancing the sealing performance of the sealing assembly 20.

As shown in connection with fig. 2, in some embodiments, the spacing between the first bead 113 and the second bead 114 is greater than the width of the seal 300. Specifically, the width of the sealing member 300 is the dimension of the sealing member 300 in the direction that the first bead 113 points to the second bead 114, and by the arrangement that the interval between the first bead 113 and the second bead 114 is greater than the width of the sealing member 300, the sealing member 300 can be installed in the installation groove 111 in a natural state, so that the sealing member 300 is ensured not to be deformed by extrusion due to installation before the compression sealing operation is performed, however, the problem that the compression amount of the connecting portion 110 is too large or too small in the compression sealing process of the sealing member 300 is caused, and the sealing performance of the sealing assembly 20 is improved.

As shown in connection with fig. 2, in some embodiments, the step 112 is provided with a pressing surface 1121, where the pressing surface 1121 is used to press the seal 300 against the bottom wall 213, and the seal 300 abuts against the first rib 113 and the second rib 114 and abuts against the bottom wall 213. Specifically, the first ribs 113 and the second ribs 114 can define the position of the seal 300 in the horizontal direction, so that the seal 300 does not loose between the first ribs 113 and the second ribs 114, and the sealing performance of the seal assembly 20 is enhanced. The pressing surface 1121 keeps a relative vertical angle with the first ribs 113 and the second ribs 114, which is beneficial to keeping the angle of the connecting portion 110 pressing down the sealing element 300 consistent along the circumferential direction in the process of pressing down the sealing element 300, so that the compression amount of the sealing element 300 is kept consistent, and the sealing performance of the sealing assembly 20 is enhanced.

As shown in connection with fig. 2 and 3, in some embodiments, the step 112 is disposed opposite the abutment surface 1121, and the step 112 is configured to abut the pawl 214. Specifically, a protrusion is formed on a side facing away from the pressing surface 1121, and the protrusion is a convex step 112, and is clamped to the convex step 112 by the claw 214, so as to be beneficial to limiting the movement of the connecting portion 110 in the vertical direction, and further, a downward pressure is applied to the convex step 112 by the claw 214, so that the pressing force between the first convex rib 113 and the second convex rib 114 and the bottom wall 213 is enhanced, the pressing stability is improved, the sealing element 300 is stably pressed against the bottom wall 213 by the connecting portion 110, and the sealing performance of the sealing assembly 20 is enhanced.
