What kind of material is good for LED mining lamp heatsink
Do you think the LED mining lamp heatsink is the same? Then you are wrong, LED lamp heatsink material is divided into many kinds, different materials of heatsink heat dissipation effect will be different, the production cost is not the same. So how many kinds of manufacturing materials are there:
1, steel heatsink: water storage, heat dissipation effect is better, light weight, spray surface beautiful, rich and diverse forms, high strength. There are requirements for the heating system (system water supply), and oxygen corrosion is easy to occur if the system is not good.
2, copper-aluminum composite heatsink: corrosion resistance, heat dissipation, heat dissipation speed, lighter than steel, more beautiful, the price is relatively high.
3, aluminum heatsink: heat transfer ability is strong, acid resistance, oxidation resistance, but easy to alkaline corrosion, there are certain requirements for water quality.
4, cast iron heatsink: good thermal inertia, mechanical strength, corrosion resistance long service life and other advantages. Appearance aesthetic fatigue, bulky, cavity sticky sand easy to damage the temperature control device. And the production is not environmentally friendly, the state has not advocated the use of.
5, stainless steel heatsink: anti-oxidation, no rust, anti-corrosion, high pressure, not easy to accumulate scale, good environmental protection, the need for external spraying adhesion is poor, high cost.
6, low carbon steel heatsink: stable quality, good thermal performance, high working pressure, light weight, but easy to oxidation corrosion water leakage.
From the current market situation, the mainstream heatsink is mainly steel and copper-aluminum composite heatsink. The steel heatsink is more cost-effective, and the copper-aluminum composite heatsink is better in quality and higher in price!
