| Abstract | ||||
| An experimental investigation is carried out to study the effect of operating parameters such as filling ratio, input heat, number of wick layers and thin coated wick on the thermal performance of a heat pipe .A film coating is a thin polymer- based coat applied to wick .the thickness of such a coating is usually between 20-100 micro meter .film coating formulations usually contain the following components: polymer, plasticizer, colourant, opacifier, and solvent. Coated material is a covering that is applied to the surface of an object ,the purpose of applying the coating may be decorative ,functional, or both ,The coating itself may be an allover coating, completely covering the substance, Functional coatings may be applied to change the surface properties of the wick, demineralized water used as working fluid. The total thermal resistance decreases with increasing filling ratio until filling ratio around between 0.5 and 0.6 then increases with increasing filling ratio, The total thermal resistance decreasing with increasing the number of coated layers of wick ,The total thermal resistance decreases with increasing heat input . | ||||
