[0002] The computing speed of components, such as a processor, in an electronic product has increased, and the heat generated is also increasing, so an air-cooled heat dissipation device is unable to meet the current heat dissipation requirements.
[0003] The prior art water-cooled heat dissipation device solves many problems existing in the air-cooled heat dissipation device, and the heat dissipation performance of the heat dissipation device is greatly improved. However, the prior art water-cooled heat dissipation device still has disadvantages, such as fluid leakage and poor airtightness, which need to be improved.
[0004] Accordingly, the applicant of the present disclosure has focused on improving the aforementioned bottlenecks. SUMMARY OF THE INVENTION
[0005] The present disclosure provides a water cooling heat dissipation device having advantages of providing a water pipe with a desirable airtight effect to effectively prevent leakage of a liquid.
[0006] Accordingly, the present disclosure provides a water-cooling heat dissipation device including a base, a heat-absorbing structure, a fluid drive mechanism, and a sealing member. The base includes an accommodating space, a heat exchange chamber, and a first tube member communicating with the heat exchange chamber. A water conduit tube is disposed between the accommodating space and the heat exchange chamber and communicates with the accommodating space and the heat exchange chamber. A circular slit is formed on an outer periphery of the water conduit tube. The heat-absorbing structure is connected to the base and disposed in the heat exchange chamber. The fluid drive mechanism is connected to the base and disposed in the accommodating space. The fluid drive mechanism includes a housing and a rotor assembly.The housing includes a chamber, a second tubular member communicating with the chamber, and a third tubular member communicating with the chamber. The rotor assembly is disposed in the chamber. The third tubular member is disposed in the circular slot and communicates with the water pipe. The sealing member is disposed in the circular slot and compressed by the third tubular member to create a partial deformation; thus, the third tubular member is tightly combined with the water pipe. The sealing member includes a bottom support, an inner ring, and an outer ring extending from the bottom support. The bottom support is abutted by the third tubular member. The outer ring is clamped between the third tubular member and an inner wall of the circular slot.
[0007] Advantages achieved by the present disclosure are as follows. The overall structure of the present disclosure is more compact with the arrangement of each component; thus, higher heat dissipation performance is provided. The double-ring design with the inner ring and the outer ring provides better tight meshing and better anti-leakage performance. By configuring the first tube member and the base in one piece, and configuring the second tube member and the housing in one piece, an effect that greatly prevents fluid leakage is provided.

After the sealing element 40 is clamped by the third pipe element 313 and the water pipe 14, the third pipe element 313 is tightly combined with the water pipe 14 by partially deforming the sealing element 40 due to the dimensional tolerance.
[0014] The sealing member 40 is disposed in the circular slot 15 and compressed by the third tube member 313 to produce a partial deformation; thus, the third tube member 313 is tightly combined with the water pipe 14. The sealing member 40 includes a bottom support 41, an inner ring 42, and an outer ring 43 extending upward from the bottom support 41. The inner ring 42 is sandwiched between the water pipe 14 and the third tube member 313. The bottom support 41 is abutted by a front end surface of the third tube member 313.

The joint plane PL is attached to and in communication with a heat-generating source (not shown in the figures). The rotor assembly 32 has a core extension line L. The core extension line L is perpendicular to the joint plane PL.
[0022] In some embodiments, the housing 31 further includes a rotary shaft support 317. The rotary shaft support 317 is disposed in the third tubular member 313.
[0023] In some embodiments, the water-cooling heat dissipation device 1 of the present disclosure further includes an electrical drive circuit board 50.
