The Application Of Heat Pipe Technology In Turbocharged Internal-Combustion Engine

With the development of I.C. engine in vehicle, the turbocharging intercooling as the important way of raising power performance and fuel economy , deceasing the thermal load and exhaust emissions has been used more and more in the exploitation of new engine.Inrercooler is the key part of the charge-air cooling. So ,some of the famous manufacturer and their research institution have not hasitated devoting great manpower and material resources in the research ,expected to developing more scientific and perfect manufacture.This article analyzed and compared the way of intercooling;designed one testing heat-pipe intercooler based on the request of high efficiency of intercooling and the characteristic of the heat pipe and heat-pipe heat-exchanger.Also,used the new energy efficiency method to analyze and optimize calculate this intercooler,and came out the optimal relation of energyefficiency and heat capacity ratio(C).Applied the computer to compile program to design the heat-pipe intercooler, which maked the research theory can be directly applied to manufacture process.In this paper,the author used the experiment of thermodynamics,and came at the function of the Nusselt number Nu and the Reynolds number Re,also came at the function of the number Eu and the Reynolds number Re.Besides,the author studied the match operation performance of the heat-pipe intercooler and diesel engine.and analyzed the influence of the power performance,fuel economy and exhaust emission.The aim of the article is to study the forground of the application of heat pipe technology in engine.So that the research of theory can be best used in manufacture.
