Description

technical field [0001] The invention relates to a formula of heat-dissipating paint and a method for making a heat sink by using the same. Background technique [0002] Because of its good heat dissipation performance, many radiators are made of metal materials such as aluminum, copper, iron or alloys, such as: automobile radiators, air-conditioning radiators are made of aluminum or copper materials, heating radiators, infrared ray Furnace pipes are made of stainless steel, various military guns / barrels are made of various alloys for heat dissipation, induction cooker radiators and LED radiators are made of aluminum materials, some of the various heating plates are made of aluminum materials, and some are made of iron. [0003] However, most of the current radiators are made of bare metal body, electrochemical or sprayed protective layer profiles: [0004] Bare metal body: ①Formulation: aluminum ingots, alloy mixed ingots, copper materials, iron materials, etc. are melted a...

Problems solved by technology

[0004] Bare metal body: ①Formulation: aluminum ingots, alloy mixed ingots, copper materials, iron materials, etc. are melted at high temperature, and various shapes of fins / pipes are cast or die-cast to increase the heat dissipation area to dissipate heat; ②Process: Metal ingot melting → pouring mold → forming; ③ Existing problems: easy to oxidize, bare metal profiles will produce an oxide layer when exposed to air or water vapor in the air, causing heat dissipation failure of the product, rapid aging or loss of function of the product ; Not resistant to acid and alkali, the current air pollution is relatively serious, acidic, automobile exhaust, industrial pollution, oil pollution, etc., bare metal profiles are oxidized, acidified, and alkalized at any time, resulting in product heat dissipation failure and rapid product aging or go to function

[0005] Electrochemical or spray-coated heat-dissipating profiles of silicone protective layer: ①Formulation: metal ingots for casting are melted at high temperature, die-casting, organic coating; ②Process: metal ingot melting→casting mold→forming→oil removal→spraying→drying→product ; ③ Existing problems: poor heat dissipation, silicone is a poor conductor of heat, coating silicone on the radiator, the purpose is to prevent metal parts from being air, acidified, alkalized or oxidized, but the metal substrate of the radiator is all coated Covering will reduce the thermal conductivity of the entire radiator, causing the product to fail in heat dissipation, causing rapid aging or loss of function of the product; it is not weather-resistant, silicone coating and electrification are greatly affected by the environment, and the thermal expansion coefficient of the coating is relatively large. Cold shrinkage, easy to crack, and eventually cause heat dissipation failure
