A heat pipe is a structurally simple device capable transfer high heat fluxes over relatively long distances. With first heat pipe concept comes Angier March in 1831 as a hermetically sealed tube used to heat transfer in furnaces. If the vapour and liquid phases are separated from each other in heat pipe, then it is a loop thermosyphon. These solution is preferably mainly therefore that the thermal performance of the loop thermosyphon is not limited by the interaction limit (condensate droplets are not entrained by the vapour flow). Loop thermosyphon can be used to heat dissipation for example in dust-free cooling of electrical boxes.
The paper deals with the condenser design for the loop thermosyphon, which is capable dissipate heat flux of 1000 W supplied from the evaporator at the condition that the temperature in the electrical box not exceed 80 °C. Heat dissipation to the surrounding are takes place without moving parts (fans) only through natural convection. The experimental verification of the heat dissipation through the loop thermosyphon was carried out at the thermal load of the electrical box of 500, 1000 and 1500 W. Water was used as a working fluid in loop thermosyphon at quantity 60 % of the evaporator volume./ |
