1. What is the need for using heat pipe based cooling solutions in my product/infrastructure?
A. Heat pipe based cooling solutions offer the most efficient transfer of heat from heat generating end to the dissipating end. The main advantages of heat pipe are the passive heat exchange without any moving parts. The cooling or heating equipment size can be reduced. There is no cross contamination between air streams.
2. What are the maintenance intervals of a heat pipe based heat sink?
A. Since the system is a totally closed one, there is no maintenance required at all. Dust accumulation in the fin stack can be an issue in an unclean environment and it can be rectified by cleaning the fin stack outer area when required.
3. I already use a heat dissipating system but want to shift to a Heat pipe based solution. Is it possible?
A. Yes it is possible to replace older heat dissipating systems by a Heat pipe based solution. Due to the compact nature of a heat pipe based heat sink/exchanger, space constraints are easily overcome.
4. What is the expected working life of a Heat sink?
A. Provided the environment and the unit is kept reasonably clean and free of corrosive elements, a heat sink can last anywhere from 10 to 15 years or in some cases more than 20 years. Performance also depends on the Thermal interface materials, so usage of better quality materials guarantees longer working life before user intervention is needed.
5. What are the environmental dangers of using these products?
A. These products are actually environmentally friendly and would serve to decrease power consumption when used for heat recovery. It is non-polluting, and a GREEN technology to serve the future.
6. What about carbon credits? Would using these products for heat recovery help in any way?
A. Almost all companies are looking to the future, and are aware of carbon credits and carbon footprint. Using Heat recovery systems in applications where energy consumption is able to be reduced automatically reduces the carbon footprint and carbon credits become more accessible.
7. Forced Convection (active cooling) vs. Natural Convection (passive cooling). Which is preferable?
A. Each of these options has its own advantages/disadvantages. More heat can be removed using a Forced Convection (Active cooling) and the space it consumes is also less in comparison to a case wherein a passive cooling system is used. The system would ‘consume power’ in terms of running the fan/blower. Also, a fan/blower can be another possible point of failure of the system or maintenance.
Natural Convection (Passive cooling) work without any fan/blower but there is a limitation on orientation of fin stack, because air flow has to be from bottom to top over the fin surface. A larger fin area is needed to dissipate same amount of heat as when compared to a Forced convection heat sink.
