TSD BN Product - Cooler Industry

 

TSD coating greatly improves cooler thermal management.

   

Not all the coolers (heat exchangers) are build to perform accordingly.  There are many technologies behind designing and building the coolers, from the selection of material, air-surface areas, flow design, etc. will greatly affect the cooling capacity.

 

However, TSD Boron Nitrides simply applying coating on the cooler will increase the thermal transfer between the materials, increase air-to-surface areas, protects alloy, and result and distinct cooler no other can compare.

 

 

Thermal Conductivity

Hexagonal boron nitride offers excellent thermal transfer and thermal radiation with superb thermal stability over wide temperature ranges.

Cooler Structure

Basic cooler design is construct of a passage tubes and cooling fins both joined by different methods, such as tin used to join for the brass coolers.

 

The passage tubing carry different form of media, from fluid, oil, air from the hot source.  The heat is then transferred to the fins for cooling.

 

Cooling is achieve by the different temperature (outside) and the object inside (fluid, oil, air, etc.).

 

 

The cooler design determine the efficiency by:

 

Flow characteristics

 

Material selection

 

Air-to-surface fine area

 

Thermal transfer capacity from passage to fines

 

 

 

BRASS Coolers

Thereof, we can see the brass cooler have better cooling capacity than aluminum coolers.  However, brass coolers are greatly degraded the performance due to the use of the tin joining the passage and fines.  Finally a layer of paint to prevent oxidation greatly reduced the overall brass coolers.

 

Brass coolers without paint and final coated with TSD BN thermal coating can achieve best cooling performance.

 

 

BN Thermal Coating Surface Characteristics

The coolers greatly benefit with TSD Boron Nitride thermal coating.  The coated surface formed a unique layer of BN plates as you can clearly see from the illustration on the right.  The fins on fins easily increase over 50% of air-to-surface contact areas as expose to cooler air flow.

 

 

BN - Excellent Radiant Heat Transfer

Surface area greatly increased from the illustration.  The heat quickly transferred onto BN surface and quickly cooled by air stream or heat radiation by the boron nitride.

 

Increase Thermal Capacity / Efficiency

You can see the join/connection of the passage and fins are covered by the BN coating to enhance the thermal transfer that normal connector lack of.

The above illustrator is the ordinary cooling construction.  The passage tubing and fins have little connection areas and often with poor thermal conductivity.

 

 

Non-wetting surface protection layer coat

The TSD BN thermal coating provides excellent surface protection capabilities.  The illustration on the right shows the stainless steel-310 is heated to 950℃ and cooled down in few cycles.  Clearly the alloy surface maintain its alloy characteristic.

 

 

Unique Exterior "WHITE" Appearance

The boron nitride coating provide a whitish ceramic finish that give a distinct appearance.  Such appearance easily marketed as it's unique property and color separation no others able to compete.

Advantages

 

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