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.

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.

完整測試數據
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.
