Heat Pipes

Capri Cables offers Heat Pipe. It is an efficient thermal transfer device. The functioning principle of a heat pipe (HP) is based on evaporation and condensation cycle of a liquid inside the HP that enables transfer of large quantities of heat along the axis of the HP with a low temperature differential between the evaporator and condenser sections of HP. When heat is transferred from a heat source to the evaporator section of the HP, the liquid in the evaporator evaporates and the vapour moves to the other end of the HP (condenser section) due to the pressure gradient. The vapour condenses due to heat rejection by forced or natural convection. Advantages: high heat transfer capacity because of high thermal conductance; maximum heat flux is achieved with minimum temperature difference; greater design freedom - can be manufactured to suit exact wattage dissipation; higher loading of electronic devices than with conventional cooling; unmatched suitability in higher wattage dissipation segment; provide for 20-40% reduction in weight and physical dimensions; no maintenance required throughout the life; very long life. Applications: cooling of semi-conductor devices like diodes, thyristors and IGBTs in rectifiers, inverters, units and modules of electronic equipment, etc; cooling of control panel and optical cable junction box; cooling of servers/computers/laptop, etc; waste heat recovery in HVAC/dehumidifiers and use in grain dryers, tobacco dryers, etc; use in die-casting and injection moulding dies; solar energy applications and also in cryogenics use. Heat pipes can be successfully used not only in radio, electro-technical and power industries, but in engineering, metallurgy, light, food and chemical industries, in construction, transport, agriculture and medicine for heat transfer and management.
