Cooler having ground heated plane for cooling heating electronic component

Abstract

A method for making heated plane of a cooler to obtain better flatness and roughness includes a grinder with a grinding plate and a fixture. Then, the cooler is arranged onto the fixture. Next, the abrasive is injected into the gap between the grinding plate and the heated plane, making the fixture press and clamp the cooler in a way, such that the heated plane of the cooler contacts the abrasive closely. Finally, the grinding plate is rotated to make at least one grinding process to the heated plane, making the heated plane obtain a surface with better roughness and flatness, further enhancing the contact tightness between the heated plane and a heating element, and therefore promoting the thermally conductive efficiency between the cooler and the heating element.

AI Technical Summary

Benefits of technology

[0009]The invention is mainly to provide a cooler with ground heated plane and a grinding method and apparatus thereof. By grinding the heated plane of the cooler, the roughness and flatness on the surface of the heated plane is improved. Furthermore, the thermally conductive effect is enhanced due to a better contact relative to the heating electronic component.

[0013]Compared with the prior arts, the invention is to arrange a fixture to a grinder. The fixture presses and clamps a cooler via a point contact manner, whereby the heated plane of the cooler can possess a better flatness and surface roughness after being ground. Therefore, the contact tightness between the heated plane and the heating electronic component is increased, further generating a better effect of thermal conduction and enhancing the practicability of the invention.

Problems solved by technology

Following progress of technology, computer hardware is developed toward the directions of high speed and high frequency for increasing its execution efficiency, but its power consumption is also increased relatively.

If the accumulative heat is not removed in time, the electronic component will be overheated to lower down the operation efficiency, even cause damage.

However, since of the limitation of many factors, such as cooling space and power consumption, how to promote cooling efficiency as high as we can becomes an issue intended to be addressed urgently by industry.

However, in practice, the roughness and flatness on the surface of the heated face is still poor, making the heated face and the heating component unable to be contacted closely, thereby, limiting the thermal conduction between the heated face and the heating electronic component.
