Design of a Heat Exchanger Made of Gravity Heat Pipes with an Enlarged Heat Exchange Surface for Heat Dissipation from the Electrical Cabinet

Abstract

Due to the great progress in the electronics industry, heat management in electronic components is becoming a serious and important problem. Cooling of electronic components ensures a lower occurrence of failure of elements, longer service life of the device, protection against overheating of elements, further prevents malfunction of the device and loss of heat. In many cases, heat dissipation by natural convection is often insufficient. Heat dissipation by forced convection is effective, but it carries the risk of clogging the interior of the electrical cabinet with dust, which can negatively affect the functionality of the electrical elements over time. One of the possibilities of efficient heat dissipation from the electrical cabinet without forced convection is by means of heat pipe technology, which uses a phase change of the working substance for heat transfer. The article deals with the design, construction and experimental determination of the performance of gravity heat tubes with an increased heat exchange area suitable for the design of an electrical cabinet heat exchanger.
