TSD BN Product - Heat Sink Thermal Test

 

 

Heat Sink with TSD Coating thermal test

August 7, 2006

   

Compare two aluminum heat sinks thermal performance between one heat sinks with TSD BN Thermal Coating and one without.

 

The heat sink contacts incorporated with TSD BN thermal pads (4.77 W/mk) for best thermal conductivity between heat sink and warmer.

 

 

Warmer unit

180W Power

 

Base temperature Prob.

158.5˚C

 

A cardboard divider also placed between both tested heat sinks preventing thermal soaking and heat radiation.

 

Setup

T1 (temperature 1) is placed on top of the heat sink measuring the heat sink temperature.

 

T2 (temperature 2) is placed on the warmer plate measuring the warmer plate temperature.

 

TSD BN thermal pad was placed between the heat sink and warmer plate.

 

Temperature recorded every 1 minute for 25 minutes.

 

Test Data

The test date recorded more than 5 ˚C lower on warmer base with TSD BN coated heat sink.  The average heat sink surface temperature measured 10˚C hotter.

 

163.2˚C

What's the advantage/function choosing TSD BN Thermal Coating?

 

The BN coating heat sinks (whitish coating) greatly improves thermal management and quickly increase thermal capacity and reduce heat from the warmer plate.

Advantages

 

TSD BN thermal coating improves thermal management by conducting thermal transfer away from the heat source.
