Professional LED Indoor Lighting Fixtures Aluminum Extrusion Heat Sink CNC Turning LED Down Light LED Spot Light Heat Sinks

Product Description

Item:Professional LED indoor lighting fixtures aluminum extrusion heat sink CNC Turning LED down light LED spot light heat sinks

Function:

Heat sink is a device for radiating easily heated electronic components in electrical
appliances. It is mostly made of aluminum alloy, brass or bronze, plate, sheet, multi
sheet, etc. its main function is to dissipate heat.

Kinds of heat sink

1. According to the processing method, there are finger radiator, profile radiator
(extruded into profile), insert radiator, casting radiator, etc.

2. According to the
cooling method, there are natural cooling radiator, air cooling radiator, liquid cooling
radiator (water cooling radiator, oil cooling radiator), cold plate radiator, heat pipe
radiator, etc.

3. According to professional purposes: Heat Dissipation Calculation of
power devices and selection of radiators. Electronic products with electronic heat sinks
mainly use patch packaging devices, but many high-power devices and some power modules
still use perforated packaging, which can be easily installed on the radiator for heat
dissipation.

4. According to the materials used: aluminum radiator, copper radiator and
steel radiator.

5. According to the power used: there are low-power radiator, medium
power radiator and high-power radiator.

6. According to the characteristics of radiator


Standard of heat sink

1. The quality of material (purity, thickness, processing accuracy, etc.) and
manufacturing process (cracks, shrinkage cavities, etc. caused by casting), poor
material and rough and defective process will directly affect the thermal conductivity
of the radiator;

2. The surface roughness and flatness of the electronic heat sink
contact table directly affect the contact thermal resistance and pressure drop;
