ABSTRACT
Intensification of cooling electronic components is to use heat transfer through phase changes. From a structural point of view it is important to create a cooling system that is able to drain the heat loss of the inverter in each mode of operation the device. That is, not only during movement, when the relative velocity of air flow around the inverter sufficiently high for forced convection, but also in the case where the device does not move, the relative humidity of the air is zero. A further important consideration is the reliability of the cooling, and therefore it is advisable to choose such a cooling system, which does not contain moving elements. One way of ensuring sufficient cooling is the use of cooling system based on phase-change working fluid, therefore heat pipes. In this article the cooling system is solved by a closed loop pulsating heat pipe.
