In this study, has been investigated the rate of heat transfer between engine and vehicle body room in steady state using analytical methods and the concept of net radiation heat transfer and energybalance equation at the boundaries. Also, calculated the net radiation heat transfer,percentage reduction in heat transfer, temperature and emissivity while there are one, two and three radiation shields with temperature- dependent emissivity.The findings reveal that,one radiation shield with lower emissivity can reduce the net heat transfer even better than two radiation shields with higher emissivity.Also, Is obtained an optimized for combination of two and three radiation shields with different materials.
