Benefits of technology

[0008]A primary object of the present invention is to provide a thermal module, which has simplified structure and can be quickly assembled.
[0009]A further object of the present invention is to provide a manufacturing method of a thermal module. By means of the manufacturing method, the thermal module can be manufactured at lower cost.

Problems solved by technology

However, in the case that the heat dissipation base seat and the heat pipes are made of different metal materials with different performances, (for example, the heat pipes are made of copper material, while the radiating fins are made of aluminum material), it will be hard to securely connect the heat dissipation base seat with the heat pipes.
However, the aluminum material cannot be welded to a copper material with different performances by means of argon welding.
Such procedure is quite troublesome.
Moreover, the thermal module with the heat dissipation base seat has a heavier weight and larger volume and is manufactured at higher cost as a whole.
It is inconvenient to install or transfer such thermal module.
Therefore, such thermal module can be hardly applied to an electronic device with narrow interior space.
1. The heat conduction efficiency is poor.
2. The manufacturing cost is higher.
3. The application site is limited.

Embodiment Construction

[0032]Please refer to FIGS. 1 and 2. FIG. 1 is a perspective exploded view of a first embodiment of the thermal module of the present invention. FIG. 2 is a perspective assembled view of the first embodiment of the thermal module of the present invention. According to the first embodiment, the thermal module 1 includes a retainer member 11 and at least one heat conduction member 12.

[0033]The retainer member 11 has a first clamping arm 111 and a second clamping arm 112 opposite to the first clamping arm 111.

[0034]The first clamping arm 111 and the retainer member 11 contain therebetween a first angle 113. The second clamping arm 112 and the retainer member 11 contain therebetween a second angle 114.

[0035]The first clamping arm 111 has a first free side 1111, a second free side 1112, a third free side 1113 and a first connection side 1114 connected with the retainer member 11. The second clamping arm 112 has a fourth free side 1121, a fifth free side 1122, a sixth free side 1123 and a...

Abstract

A thermal module and a manufacturing method thereof. The thermal module includes a retainer member and at least one heat conduction member. The retainer has a first clamping arm and a second clamping arm opposite to the first clamping arm. The heat conduction member is disposed and fixedly clamped between the first and second clamping arms. The retainer member is formed by means of punching and integrally connected with the heat conduction member also by means of punching so that the manufacturing cost of the thermal module is lowered and the heat dissipation efficiency of the thermal module is enhanced.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a thermal module and a manufacturing method thereof, and more particularly to a thermal module manufactured at lower cost and a manufacturing method of the thermal module.BACKGROUND OF THE INVENTION[0002]A conventional thermal module is mainly composed of a heat dissipation base seat and heat pipes passing through the heat dissipation base seat. The heat pipes are generally securely affixed to the heat dissipation base seat by means of welding. However, in the case that the heat dissipation base seat and the heat pipes are made of different metal materials with different performances, (for example, the heat pipes are made of copper material, while the radiating fins are made of aluminum material), it will be hard to securely connect the heat dissipation base seat with the heat pipes. This is because an aluminum material can be hardly connected with other kinds of materials by means of common welding process. An aluminum ma...
