Heat dissipation assembly

Heat dissipation assembly description/claims

1. Field of the Invention

The present invention is related to a heat dissipation assembly and particularly to a heat dissipation assembly in which a heat pipe with a curved section and a curved shaped cooling fin set with a curved recess for being attached to the curved section.

2. Brief Description of the Related Art

The conventional heat dissipation assembly, which provides a heat pipe and a cooling fin set, can be classified into three categories.

The first category of the conventional heat dissipation assembly is Taiwan Utility Model Application No. 094221564, entitled “ASSEMBLABLE HEAT DISSIPATION DEVICE”, which discloses a heat pipe with a horizontally extended curved section being attached to a first cooling fin set and a second cooling fin set, which provide a recess respectively.

The second category of the conventional heat dissipation assembly is Taiwan Utility Model Application No. 094222753, entitled “HEAT DISSIPATION DEVICE”, which discloses a heat pipe with an upright extended curved section passing through at least a cooling fin set.

The third category of the conventional heat dissipation assembly is Taiwan Utility Model Application No. 094210338, entitled “COOLING FINS ASSEMBLY”, which discloses a heat pipe passing through a plurality of cooling fins and then having a curved shape.

However, the first and second categories of the conventional heat dissipation assemblies have a common feature that the curved sections of the heat pipes are attached to the cooling fin sets and the horizontally extending curved section of the heat pipe provided in the first category of the conventional heat dissipation assembly occupies more space and is too close to the motherboard. The curved shaped section of the heat pipe provided in the third category of the conventional heat dissipation assembly is fabricated after the heat pipe being attached to the cooling fin set such that it is incapable of controlling the size of curved shaped section in the process of fabricating effectively.

In order to overcome the deficiencies of the preceding prior art, a primary object of the present invention is to provide a heat dissipation assembly in which a heat pipe with an upright curved section and the cooling fin set with a lateral curved recess are attached to each other precisely.

Another object of the present invention is to provide a heat dissipation assembly in which the curved section of a heat pipe is made with a preset tortuotsity before the lateral recess of a cooling fin set is attached to the curved section.

A further object of the present invention is to provide a heat dissipation assembly with which the sizes of the upright curved section of the heat pipe and the lateral curved recess of the cooling fin set can be controlled effectively during the heat pipe and the cooling fin set being fabricated.

Accordingly, a heat dissipation assembly according to the present invention includes a heat pipe and a cooling fin set. The heat pipe provides an upright curved section and the cooling fin set provides a plurality of cooling fins to be attached to the curved section. Wherein, the cooling fin set has a curved shape corresponding to the curved section and provides a lateral curved recess for the curved section being capable of fitting with the curved recess precisely due to the sizes of the curved section and the curved cooling fin are controlled effectively and the required tortuosity is obtained during being worked.

The detail structure, the applied principle, the function and the effectiveness of the present invention can be more fully understood with reference to the following description and accompanying drawings, in which:

FIG. 1 is an exploded perspective view of a heat dissipation assembly according to the present invention;

FIG. 2 is an assembled perspective view of a heat dissipation assembly according the present invention; and

FIG. 3 is a sectional view of a heat dissipation assembly according the present invention.
