Design and experimental analysis of the heat transfer panel with capillary imbibition core
摘要
Abstract
Serpentine radiant heat transfer pipes（SRHTP）are expensive and with low heat exchanged,so the heat transfer panel with capillary imbibition core（HTPCIC） is put forward.HTPCIC is composed by potassium citrate-plaster（PCP）,and PCP board becomes a uniform channel of which the flow rate is 55.3% when water is cooling medium.By changing the emissivity of HTPCIC＇ surface（low emissivity 0.23,high emissivity 0.95）and the temperature of cold-water（7~18 ℃）,at 26 ℃（±1 ℃）,heat transfer characteristics of HTPCIC are analyzed whose average pore radius is 0.015 mm and porosity is 55.3%.The experimental results show that the cooling capacity of HTPCIC meets the requirements of conventional radiation air-conditioning,and compared with SRHTP,the initial cost reduces by 80%.Moreover,regression equation of the HTPCIC heat transfer guideline is proposed： Nu=0.029Re0.21Pr2.6θ0,which provides basis for establishing a complete design theory.关键词
