Fluid return is normally accomplished by gravity. The constant circulation of evaporating and condensing of the working fluid is the principle of heat pipes heat transfer. Heat pipes can transfer heat with minimal temperature difference between one end and the other.
If the products of the endothermic reaction are stored, the chemical heat pipe can also be operated as a thermochemical heat storage system, thereby combining both a distribution possibility for thermal energy that is in principle free of losses as well as a thermochemical energy storage.
For obtaining better thermal performance, it is recommended that the condenser length should be higher than the evaporator. The parameters affecting the design of a heat pipe are; Type of heat pipe, Material of heat pipe, Selection of wick, and Selection of working fluid.
The thermal characteristics of heat pipes are limited by the thermo-physical properties of working fluids. The low thermal properties of conventional fluids restrict heat pipes for high heat flux applications.
General schematic of standard heat pipe configuration. The temperature drop in the system is minimal due to the very high heat transfer coefficients for boiling and condensation. Effective thermal conductivities can approach 10,000–100,000 W/m K for long heat pipes, in comparison with roughly 400 W/m K for copper.
Thermal resistance, effective thermal conductivity, heat transfer coefficient, and thermal efficiency are the foremost parameters for analyzing the thermal performance of heat pipes. Thermosyphon is used for shallow and deep geothermal energy applications; however, Loop and oscillating heat pipes are preferred in electronic cooling.
