In present are electrical boxes cooled by air through the intake hole on the bottom electrical box to the box space with electrotechnical elements and exhaust through the hole at the top to the surrounding by natural convection. This cooling method is effective but operate with the risk of contamination electrotechnical elements by dust sucking from surrounding air. The goal of this work is solution of the dustproof cooling of the electrical box by natural convection. The work deal with design of the device with the heat transfer by the phase change of the working fluid and experimental measuring its thermal performance at the cooling electrotechnical elements loaded by heat 1 200 W in the dustproof electrical box.

“…In the adiabatic section is not exchanged heat transfer through the ambient area, due to the isolation of a few working fluid to the wall of the heat pipe condensation film of condensed working fluid. In the condenser the vapour of working fluid condenses on the walls of the heat pipe, which transmit latent (condensing) heat through the walls of the heat pipe to the heat consumption point [5,6,7]. Figure 1 presents heat pipe model and heat pipe schema.…”

Abstract. The article deals with the creation of the basis of the CFD model of the heat pipe, which is designed to simulate and show the predicted course of the work-fluid-activity within the heat pipe. This simulation is part of the study of the heat pipe device. This device, based on CFD simulation, can be constructed to describe the phenomena running inside the heat pipe based on real-world experimental measurements. A comparison of the CFD and the experimental model can explain the problems of areas and phenomena in the heat pipe. Based on this comparison, it is possible to optimize single device errors. The optimization transferred to the CFD model will show us how to solve problems and how to improve the experimental models of heat pipes.

“…To prevent escape of vapour, it should not be porous. The material should have high strength but, at the same time, it should be easily machineable and compatible with the working fluid [3]. The evaporator body is a plate with dimensions 116 x 206 x 30 mm.…”

Abstract. This work deal with evaluation of condenser temperature by experimental measurement, calculation and thermal visualization of cooling device working with a heat pipe technology. The referred device in the article is cooling device capable transfer high heat fluxes from electric elements to the surrounding. One from many things influenced the heat flux amount transferred from electronic elements through the cooling device to the surrounding is condenser construction, its capacity and option of heat removal. The work contain description, working principle and construction of cooling device. Experimental part describe the measuring method and mathematical calculation to condenser temperature evaluation of cooling device depending on the loaded heat of electronic components in range from 250 to 750 W. The mathematical calculation is based on physical phenomena of boiling, condensation and natural convection heat transfer. The results of experimental measurement and mathematical calculation are verified by thermal imagining of device condenser by IR camera.
