Method for producing heat radiator

Abstract

This invention provides a method for manufacturing radiators including the following steps: providing multiple radiating fins, processing the surfaces of them to let the surfaces have charges of a first kind of electricity, processing prepared multiple carbon nm tubes to let one end of which have charges of a second kind of electricity opposite to the first, putting the electric multiple carbon nm tubes and fins in a solution to adsorb the tubes to the surfaces of the radiating fins, which applies the static adsorption character to assemble the carbon nm tubes on the surfaces of the radiating fins to be distributed more uniformly on the fins.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing a radiator, in particular to a method for manufacturing a radiator with carbon nanotubes on its surface. 【Background technique】 [0002] In recent years, with the rapid development of the integration process of semiconductor devices, the degree of integration of semiconductor devices has become higher and higher. However, the volume of devices has become smaller and smaller, and their demand for heat dissipation has become higher and higher. more important question. To meet this requirement, various heat dissipation methods such as fan heat dissipation, water-cooled auxiliary heat dissipation, and heat pipe heat dissipation have been widely used, and certain heat dissipation effects have been obtained. [0003] The two most important heat dissipation paths in a heat sink are heat conduction and heat convection. Heat conduction refers to the exchange of energy between molecules. Molecules with les...

Problems solved by technology

However, the use of chemical vapor deposition to grow carbon nanotube arrays requires a catalyst layer to be deposited on the surface of the heat dissipation fins. The uniformity of the catalyst layer will affect the uniformity of the formed carbon nanotube arrays, and the current radiator fins The spacing is very small. Affected by the small spacing, it is very difficult to deposit a uniform catalyst layer on the surface of the heat dissipation fin, which makes it difficult to grow a uniform carbon nanotube array on the surface of the heat dissipation fin, which ultimately affects the heat dissipation of the radiator.
