Abstract
This paper presents research results on heat pipe numerical models as optimization of heat pipe heat exchangers for intensification of heat exchange processes and the creation of heat exchangers with high efficiency while reducing their dimensions. This work and results will allow for the extension of their application in passive and low-energy construction. New findings will provide a broader understanding of how heat pipes work and discover their potential to intensify heat transfer processes, heat recovery and the development of low-energy building engineering. The need to conduct research and analyses on the subject of this study is conditioned by the need to save primary energy in both construction engineering and industry. The need to save primary energy and reduce emissions of carbon dioxide and other pollutants has been imposed on the EU Member States through multiple directives and regulations. The presented numerical model of the heat pipe and the results of computer simulations are identical to the experimental results for all tested heat pipe geometries, the presented working factors and their best degrees of filling.

This paper presents research results on heat pipe numerical models as optimization of heat pipe heat exchangers for intensification of heat exchange processes and the creation of heat exchangers with high efficiency while reducing their dimensions
The presented numerical model of the heat pipe and the results of computer simulations are a continuation, as well as an attempt to visualize the experimental tests for the tested heat pipe geometries, as well as the presented work factors and their best filling levels, selected on the basis of experimental tests [6]
Computer simulations confirmed the negligible heat transfer through a heat pipe filled with air, which is the same as the results of experimental studies [30]
