How Many Heat Sink Types for LEDs Do You Know

The number one killer of LEDs is heat, so a well-designed thermal management system is critical for the longevity of your LED lighting. Now we turn our focus to passive cooling, or the use of heat sinks to manage heat in LEDs.


There are three main types of heat sink: metal heat sink, heat pipe heat sink, ICE heat sink.


Metal Heat Sink
Utilizes thermal conduction property of metals
Slow heat transfer
Inefficient air flow
Requires large quantity of raw materials
Heavy weight and manufacturing cost

Heat Pipe Heat Sink
Utilizes high thermal conduction property of heat pipes
Heat pipe’s heat transfer rate is high (40,000KW/m³·℃) but is slows down through metal plate(401 KW/m³·℃)
Inefficient air flow
Requires large quantity of raw materials
Heavy weight and manufacturing cost

ICE Heat Sink
Utilizes high thermal conduction property and heat dissipation ice pipes
Heat transfer rate=40,000(KW/m³·℃)
Excellent air flow and no limitation of direction
Sufficient heat dissipation area
Requires less raw materials
Reduced weight and manufacturing cost
