Abstract

A water-cooling heat dissipator mounted on an electronic heat-generating element includes a water-cooling head member and at least one heat pipe. The water-cooling head member includes a first cover and a second cover connected to the first cover. Both ends of the first cover and the second cover are formed with a receiving portion corresponding to each other, respectively. The receiving portions are adapted to be connected to the conduit connectors. A channel portion is formed between the first cover and the second cover for receiving one end of the heat pipe. With the above arrangement, the present invention can perform the heat dissipations of different heat-generating elements simultaneously to make the heat-generating elements operate under acceptable working temperatures. Further, the present invention can be widely used in the heat dissipation of compact electronic products.

Claims (21)

1. A water-cooling heat dissipator, comprising:

a water-cooling head member having a first cover and a second cover connected to the first cover, both ends of each cover formed with receiving portions correspondingly to each other, the receiving portions connected to conduit connectors, respectively, and a channel portion formed between the first cover and the second cover, the conduit connectors being in communication with the channel portion and the conduit connectors being configured for providing a liquid to the channel portion; and

at least one heat pipe received in the channel portion of the water-cooling head member at one end thereof.

2. The water-cooling heat dissipator according to claim 1 , wherein the water-cooling head member is formed into H-shaped.

3. The water-cooling heat dissipator according to claim 1 , wherein the receiving portion comprises an upper receiving portion and a lower receiving portion, a bottom of the upper receiving portion is recessed into the first cover, and a bottom of the lower receiving portion is recessed into the second cover, so that the height of the channel portion is identical to the inner diameter of each conduit connector.

4. The water-cooling heat dissipator according to claim 3 , wherein each receiving portion is formed into semi-circular.

5. The water-cooling heat dissipator according to claim 1 , wherein the height of the channel portion is identical to the inner diameter of the conduit connectors.

6. The water-cooling heat dissipator according to claim 1 , wherein the first cover and the second cover are provided at one side with a clamping portion corresponding to each other for connecting to the heat pipe.

7. The water-cooling heat dissipator according to claim 6 , wherein the clamping portion comprises an upper clamping portion and a lower clamping portion, the upper clamping portion projects from the first cover, and the lower clamping portion projects from the second cover, so that a space is formed between the outer wall of the heat pipe and the inner walls of the first cover and the second cover.

8. The water-cooling heat dissipator according to claim 7 , wherein each clamping portion is formed into semi-circular.

9. The water-cooling heat dissipator according to claim 1 , wherein the heat pipe is formed into either L-shaped or U-shaped.

10. The water-cooling heat dissipator according to claim 1 , further comprising a heat-conducting block connected to the other end of the heat pipe.

11. A water-cooling heat dissipator, comprising:

a water-cooling head member having a first cover and a second cover connected to the first cover, both ends of each cover formed with receiving portions correspondingly to each other, the receiving portions connected to conduit connectors, respectively, and a channel portion formed between the first cover and the second cover; and

at least one heat pipe received in the channel portion of the water-cooling head member at one end thereof,

wherein the receiving portion comprises an upper receiving portion and a lower receiving portion, a bottom of the upper receiving portion is recessed into the first cover, and a bottom of the lower receiving portion is recessed into the second cover, so that the height of the channel portion is identical to the inner diameter of each conduit connector.

12. The water-cooling heat dissipator according to claim 11 , wherein each receiving portion is formed into semi-circular.

13. A water-cooling heat dissipator, comprising:

a water-cooling head member having a first cover and a second cover connected to the first cover, both ends of each cover formed with receiving portions correspondingly to each other, the receiving portions connected to conduit connectors, respectively, and a channel portion formed between the first cover and the second cover; and

at least one heat pipe received in the channel portion of the water-cooling head member at one end thereof,

wherein the height of the channel portion is identical to the inner diameter of the conduit connectors.
