cause the housing to deform due to the different
cooling rates of the surfaces.
Do not remove the cover before the thermal barrier
is in place.
Since the heat absorbed by the thermal barrier
continues to affect the temperature of the heat
sink and data logger, remove these parts from the
thermal barrier as soon as the test is completed.
Allow them to cool down before further use. In
most cases cooling overnight is sufficient.
Always take the heat sinks out of the thermal
barrier. Shake the heat sinks to find out whether
the cooling agent has changed form solid to liquid
state. If the cooling agent is still in a solid state, the
heat sinks need to cool down for 8 hours at a tem-
perature lower than +10 °C. If the cooling agent
has remained solid, it is sufficient to cool down the
heat sinks for 8 hours at a temperature lower than
+20 °C.
Make sure that mechanically damaged heat sinks
don’t leak.
Contact BYK-Gardner if the heat sink phase
change material leaks. It is a non-toxic waxlike
substance that dries hard powdery white and
has a slight acidic smell. Wait until it is dry before
scraping off any material that has leaked onto the
surface of the barrier.
The cooling agent is a non dangerous substance
or no dangerous mixture in the sense of the
EUROPEAN UNION guideline 67/548/EWG or
1999/45/EG.
Examine the cooled thermal barrier and heat sinks
for damage before storing in a dry environment to
avoid the ceramic insulation absorbing water.
Check the thermal barrier’s seals and closing me-
chanism, rectify any damage before further use.
