What is it about?
Performance simulation and optimization of new radiant floor heating based on micro heat pipe array.The MHPA is composed of multiple independent small channels. The porous channels are connected in parallel in order to increase the specific surface area, and use the internal phase change of the heat transfer to improve heat transfer efficiency. The results from a large number of experimental studies indicate that the maximum heat flux of the flat MHPA can reach 200 W/cm2.

Why is it important?
We used research focusing on new radiant floor heating, with advantages including high efficiency heat transfer, low water supply temperature, simple waterway structure, low resistance and leakage risk, to provide theory and data to support the application of an effective radiant floor heating based on MHPA.
Perspectives
there is still no research on the thermal performance of the MHPA when applied to radiant floor heating system, and due to limitations posed by the experimental conditions, part of the internal distribution temperature cannot be obtained. Therefore, this study uses Fluent software modeling to apply MHPA to radiant floor heating systems and design different floor heating forms. The accuracy of the model was verified using previous experimental data, and the heat transfer performances of various forms of radiant floor heating were studied. In order to provide theoretical and data support for the application of the effective radiant floor heating based on MHPA.
