Analysis on Heat-Insulating Property of the New-Type Water Transporting Vehicle Based on ANSYS

Abstract

A new-type heat-insulating water transporting vehicle is designed to solve the problem that water transported in cold area is apt to be frozen. The vehicle shall be actively heated and passively heat-insulated with fuel oil heater and polyurethane insulation layer. Furthermore, it also can be automatically heated with the special management system by controlling the heater according to the water temperature and the ambient temperature. In order to study on the heat-insulation property of the vehicle, the temperature distribution of the water in the tank and heat losses from the tank with ANSYS; finally, the low temperature environmental test is carried out. The test result shows that the water temperature in the tank is reduced from 20°C to 19°C for 24h under ambient temperature of -25°C, the average overall heat transferring coefficient is 0.52W/(m2•K) and thus completely meets requirements for water transporting in cold areas.
