Heat dissipation module

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...

Benefits of technology

[0007]In order to overcome the deficiencies of the prior art, an object of the present invention is to provide a heat dissipation module, which is capable of not only enhancing the heat transfer efficiency but also lower the cost and the weight thereof effectively.

[0008]Accordingly, a heat dissipation module according to the present invention 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.

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.
