Heat Dissipation from Power Electronic Components and Electrical Enclosures Using the Gravity Loop Heat Pipe

At present, a great accent is placed on the right method of heat dissipation and waste heat recovery. The research work deals with the removal of heat from the internal space of the electrical box. Waste heat generated by the operation of electrical equipment is undesirable for their proper function. The research is focused mainly on the dissipation of Joule’s heat and its use is subject to further investigation. The first part describes various methods of cooling electrical boxes and the second part describes our specific method of cooling for electrical boxes. The investigated cooling system operates on the principle of a gravity loop thermosiphon. This type of cooling is an energy and structurally simple method because it is based on a phase change of the working substance. Another advantage is the removal of waste heat without contamination of the interior by external dirt and dust. The work results were obtained experimental on the measuring device. The measurements were performed at different heat loads and at different amounts of working substance in the cooling system. The measurement results evaluation and their comparison provide relevant data about the cooling capacity of the cooling system and indicate which working substance volume is effective at various heat load at the same time.
