An Experimental Study of Heat Pipe Heat Exchanger Insulated with Vacuum Chamber under Natural Convection for Butanol and Methanol used as Functioning Fluid

A methodical replica has been evolutes to resolve heat execution of HPHEVC under free convection cooling conditions by acquiring heat protection commence. The replica estimates the CCHT and RHT of the HPHEVC under free convection. The experimental results existed at 00 , 150 , 300 , 450 and 600 tilt angles from vertical axis of HPHEVC at different – different inlet temperature of evaporator when methanol & butanol is utilized as functioning fluids.The experimental setup has been invented in a manner such that the performance of the HPHEVC can be evaluated at separate tilt angles under free convection conditions.The innovative opinions disclose that inclination of pipe & inlet temperature of evaporator influence the CCHT and RHT of the HPHEVC under natural convection.The tilt angle of heat pipe increases from 00 to 150 the heat transport rate decreases, and it starts increasing beyond 150 tilt angle after that again start decreasing heat transport rate from 450 to 600 tilt angle for all the inlet temperature of evaporator. HPHE gives the good performance when butanol used as functioning fluid as compare to methanol.
