Sažetak
The heat pipe is a device of very high thermal conductance. Because of their superior heat conductivity, heat pipes are prime candidates for applications involving the utilization of solar and geothermal energy and the recovery of waste heat. Nowadays, heat pipes have become the stage of mass production. In this work from the available literature some of applications are presented. Due to superior heat transfer and other favorable characteristics, further expansion of heat pipe applications is to be expected at different types of solar collectors and solar energy utilization generally. Heat pipe de-icing and snow melting systems of the highway pavement, and heat pipe heating systems in the room or in the greenhouse, utilizing natural stored geothermal energy of the earth and of the underground water or the drainage from hot springs and sea have been developed and investigated. Features of those systems are no moving parts and no external power requirement, implying high reliability, i.e. maintenance free. A heat exchanger using heat pipes can efficiently be used to transfer heat between fluid streams having a small difference in temperature, such as with low-grade heat. Also, due to their particular performance characteristics, a heat pipe heat exchanger can be used where other conventional heat exchangers become inappropriate. As heat exchangers is often an integral part of most conventional energy conversion systems, improvements in heat exchanger design, therefore, mean an increase in the effectiveness of the total energy conversion process. Heat pipe heat exchangers are very reliable because they have not moving parts and since every element is separate, the exchanger acts like many conventional ones in parallel.
