Presenting the findings of an experimental examination of heat transmission during pool boiling on microstructure copper heating surfaces modified in various ways, this paper. The microstructured surfaces are fabricated using the wire-cutting machine, laser-processed surface technique, and sandpaper. Using pure water as the pool boiling liquid, microstructured surfaces’ heat transfer coefficients (HTC) are estimated experimentally. The tests are conducted at atmospheric pressure in a saturated pool boiling state with a heat flux ranging from 50 to 580 kW/m2 . The results showed that a maximum improvement of 51–92 % was obtained using composite surface modification technology by forming a microscopic structure on the surface of the heat source.
