Simulation Analysis of Comprehensive Thermal Conductivity of Copper-Based Alloy Water Jacket

In order to investigate the effect of alloy tube on the thermal conductivity of copper-based alloy water jacket, a mathematical model of comprehensive heat transfer was established for the copper-based alloy water jacket, and the effect of the thermal conductivity of alloy tube on the comprehensive thermal conductivity of alloy water jacket, the effect of cooling water velocity and the thermal conductivity of alloy tube on the heat transfer coefficient between alloy water jacket and cooling water were all investigated. The results show that with the flow rate of 1.5 m/s for the cooling water, the heat transfer coefficient between the alloy water jacket and the cooling water increases with the increase of the thermal conductivity of the alloy tube. When the thermal conductivity of the alloy tube increases from 2 W/(m·K) to 50 W/(m·K), the heat transfer coefficient between the water jacket and the cooling water increases by nearly 10 times, but when the thermal conductivity of the alloy tube is greater than 100 W/(m·K), its influence on the heat transfer coefficient between the water jacket and the cooling water becomes less. It is suggested that the thermal conductivity of the alloy water jacket should be controlled at 20~100 W/(m·K) in deciding the alloy material of alloy water jacket.
