Problems solved by technology

[0003] As the functions of these components become more powerful, the heat generated by the work will be higher, so that the matching heat sink needs to be larger to have enough heat dissipation surface area, resulting in the entire product becoming larger and heavier, which is not conducive to today's emphasis on compactness. The trend of personal and portable product design
[0004] In addition, because of the products equipped with these components, some are used outdoors where th...

Embodiment Construction

[0019] Depend on figure 1 As shown, the preparation method of the spraying and condensation heat dissipation film of the present invention is mainly composed of a weight filling ratio of 25% to 30% of the whole, granulation and selection of silicon carbide 1, and the weight filling ratio of the whole About 10% Teflon-based resin 2, and the total weight filling ratio of ketone / alcohol 3 diluent substantially accounts for 60% to 65% of the whole compound. This combination ratio is obtained from many experiments and can be mixed together. Stir into a spray paint that can be dried and condensed into a heat dissipation film on the surface of the object to dissipate heat, or on the heat sink installed on the surface of the object to dissipate heat, to achieve more convenient and improved heat dissipation efficiency, reduce dependence on large heat sinks, and cost-effective, recycling It is easy to reuse, and there is no need to carry out highly polluting anodic anti-oxidation treatm...

Abstract

The invention discloses a component sprayed with a condensed heat dissipation membrane. Pelleted and selected silicon carbide which is prepared with a weight filling proportion substance, and accounts for 25%-30% of the total amount, teflon resin which is prepared with the weight filling proportion substance and accounts for 10% of the total amount, and a ketone/alcohol dilute material which is prepared with the weight filling proportion substance and is 60%-65% of the total amount are commonly mixed, stirred, and sprayed on the surface of a workpiece to be subject to heat dissipation, and are dried and condensed into a spraying material of the heat dissipation membrane with predetermined thickness, thus simply improving heat dissipation efficiency, and lowering the dependence on a large heat dissipation piece; the component has economical cost, is easy for recycling, and does not need high-pollution anodic antioxidant processing, and has good acid and base resistance and weather fastness.

Description

technical field [0001] The invention relates to a composition for spraying and condensing heat dissipation film. Background technique [0002] Many working and heating elements need to strengthen the heat dissipation of the working and heating elements, such as the CPU of a computer or a high-illuminance LED circuit board, etc., all need a good heat dissipation structure in order to operate normally and maintain the service life of the product. Most of the heating elements are stacked with heat sinks on the back (the heating element itself, or the heating element and the heat sink can be referred to as heat dissipation parts) to enhance the heat dissipation function, although some electronic fans are also stacked , to further do forced heat dissipation, but basically it is mainly to stack heat sinks that do not require power. [0003] As the functions of these components become more powerful, the heat generated by the work will be higher, so that the matching heat sink need...
