Design of Condensing Exchanger of Thermosyphon Heat Pipe for Cooling of Electrotechnical Box.

The paper proposes a design of a condensing heat exchanger of thermosyphon loop heat pipe for cooling of electrotechnical box. The heat pipe appears to be a very good cooling device that does not require any mechanical device in its construction. A heat pipe is a structurally simple device capable of transmitting high heat flows over relatively long distances. It may be of circular or other cross-section. If one part of the heat pipe is heated - the evaporator and the other cooled - the condenser, there is a constant evaporation and condensation of the working fluid. The section between the evaporator and the condenser where there is no phase change is called adiabatic section. The heat transfer in the heat pipe is based on the phase change principle. The design of the condensing exchanger must ensure condensation of the vapor phase and heat the environment to the surrounding environment in an ideal state only by natural convection. The article describes the design of a condensing exchanger and the impact of the amount of working fluid on performance heat pipes. [ABSTRACT FROM AUTHOR]
