Investigation of the thermal performance of heat pipe heat exchanger under natural convectin

Abstract

newline 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 CCHT and RHT of the HPHEVC under free convection have been calibrated by transmuting replica into the computer program, whose interpretation coming from the conventional methodology. The replica resolves the RHT of a HPHEVC. Inventive outcomes, which existed at 00, 150, 300, 450, and 600 tilt angles from the vertical axis of HPHEVC, for the HPHEVC; have been analyzed with outcomes anticipated by a methodical replica for validating the replica when Water, Ethanol, methanol and Butanol is utilized as functioning fluids. The test setup has been invented so that the execution of the HPHEVC can be estimated at separate tilt angles under free convection conditions. The inventive outcomes validate by the methodical outcomes for the same conditions has been executed on HP at a different inclination of HP from the vertical axis, i.e., 00, 150, 300, 450 and 600 and various temperatures of the heating fluid, i.e., 40, 43, 46, 49, 52, 55, 58 and 610C at in the HPHEVC at climate temperature of around 25±10C when Water, Ethanol, methanol and Butanol used as functioning fluid. The innovative opinions disclose that the evaporator slope of HP and inlet temperature influences the CCHT and RHT of the HPHEVC under natural convection. The CCHT and RHT are increasing as rising inlet temperature and CCHT and RHT decrease as the inclination of HP increase from the vertical axis. As the slope of HP increases from the vertical axis 00 to 150, the RHT increases and starts decreasing beyond 150 tilt angles for inlet the evaporator Temperature 61 0C for Methanol, Ethanol and Butanol utilized as functioning fluids. The functioning fluid selection is based on the price, accessibility, agreement with container materials, and vapor temperature variety. The other reflection for selecting the working fluid is the best heating strength, quickly converts liquid into vapor, viscosities must be low, and vapor pressure according to the working temperature variety. Water, Ethanol, Methanol, and Acetone or Butanol are satisfying all the above parameters, so these fluids are utilizing as functioning fluids in this setup. Ethanol or simply alcohol is an explosive, flammable and colorless liquid. The fermentation of sugar produces it. The other name of Methanol is methyl alcohol. Methanol is a polar solvent, explosive, colorless, and flammable liquid. Acetone or Butanol, or propanone is an organic
