Benefits of technology

The present invention provides a heat dissipation module that improves heat transfer efficiency while reducing cost and weight. The module consists of an aluminum cooling block with a plurality of fins and a copper base. The cooling block has a central recess with a through hole, and the base fits with the recess and has a support leg that inserts into the through hole. This design allows for rapid and effective heat transfer to the fins of the cooling block.

Problems solved by technology

Although the improved heat sink shown in FIG. 7 has combined the two different metals, aluminum and copper, to enhance the heat transfer efficiency, the cost and weight of the heat sink is unable to be lowered down significantly because of the solid copper cylindrical member 20a.

first embodiment

[0017]Referring to FIGS. 1 and 2, a heat dissipation module according to the present invention includes a rectangular cooling block 11 and a base 12. The cooling block 11 is made of aluminum and a plurality of fins 111 extend outward radially from the periphery of the cooling block 11. The bottom of the cooling block 11 has a central recess and at least an elongated through hole 112 pierces the cooling block 11 from the top to the bottom thereof. Further, the respective through hole 112 is parallel to the axial line of the cooling blocks 11. The through hole 112 has a rectangular-shaped periphery hole shown in FIGS. 1 and 2 and the respective rectangular through hole 112 is arranged to space apart from each other near the four sides of the cooling block 11.

[0018]The base 12, which is made of copper, is employed to fit with the central recess of the cooling block 11 and provides a plurality of elongated upright support legs 121 corresponding to the through holes 112. That is, the num...

second embodiment

[0020]Referring to FIGS. 4 and 5, the of a heat dissipation module according to the present invention is illustrated. The cooling block 21 is cylindrical and made of aluminum with a plurality of fins 211 extending outward radially from the circumferential side of the cooling block 11. The bottom of the cooling block 21 has a circular central recess and at least an elongated through hole 212 pierces the cooling block 21 from the top to the bottom thereof. Further, the respective through hole is parallel with the axial line of the cooling block 21. The respective through hole 212 has a circular periphery and is arranged in a way of spacing apart from each other near the circumferential side of the cooling block 11.

[0021]The base 22, which is made of copper, is employed to fit with the central recess of the cooling block 21 and provides a plurality of elongated upright circular support legs 221 corresponding to the through holes 212. That is, the number of the support legs 221 is the s...

Abstract

A heat dissipation module comprises an aluminum cooling block and a copper base. The cooling block has a plurality of fins extending outward radially from the periphery of the cooling block. The base fits with the cooling block. A central recess is disposed at the bottom of the cooling block with at least an elongated through hole piercing the cooling block from the recess to the top of the cooling block. The base fits with the recess and has at least a support leg corresponding to the respective through hole to insert into the respective through hole. The heat dissipation module is less in cost and weight and enables the heat source to transmit to the fins of the cooling block rapidly and effectively.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is related to a heat dissipation module and particularly to a heat dissipation module, which is capable of removing the heat effectively and lowering the cost greatly.[0003]2. Brief Description of the Related Art[0004]It is known that various electronic devices have been developed with incessantly progress of technology. Taking the most popular electronic device, the computer, as an example, the central processing unit (CPU) on the main board runs in company with the heat generation. The generated heat increases along with better performance of the CPU. In order to keep running normally for the computer, it is necessary to lower the temperature of the CPU. Usually, the prior art to solve the problem of heat dissipation is to add more heat sinks for removing the generated heat outward. The conventional heat sink is made of copper or aluminum. The aluminum heat sink is lighter and cheaper than the co...
