Problems solved by technology

[0002] The existing radiators for water medium heating are made of various metal materials, which have the disadvantages of high cost, high maintenance cost, waste of resources, serious pollution, easy corrosion, and short service life.
In recent years, there have also been individual reports on the use of modified polypropylene and polyethylene materials to prepare radiators and other devices, but they have not been practically used because the heat dissipation performance and working pressure cannot meet the requirements of the use environment of water-based radiators.

Abstract

The present invention relates to is mineral-base composite material and the heat sink therewith. The mineral-base composite material is prepared with 1500-3000 mesh graphite powder, polypropylene, carbon fiber, cross-linking agent and antioxidant, and through high speed stirring and pelletizing. The heat sink with the mineral-base composite material is made through injection molding in an injection molding machine and welding with one sweating welder.

Description

technical field [0001] The invention relates to a novel mineral-based composite material radiator used for water-medium heating and a preparation method of raw materials thereof. Background technique [0002] The existing radiators for water medium heating are all made of various metal materials, which have the disadvantages of high cost, high maintenance cost, waste of resources, serious pollution, easy corrosion, and short service life. In recent years, there have also been individual reports on the use of modified polypropylene and polyethylene materials to prepare radiators and other devices, but they have not been used in practice because the heat dissipation performance and working pressure cannot meet the requirements of the use environment of water-based radiators. Contents of the invention [0003] The object of the present invention is to provide a mineral-based composite material with excellent thermal conductivity, a heat sink made of this material and a manufa...
