Combination Heat Exchangers for Industrial and Agricultural Vehicles 740690

Analysis of vehicle systems performance data of a radiator, air-cooled oil cooler, and air-conditioning condenser is presented. The effects of adding individual heat exchangers ahead of the radiator are reviewed with emphasis on uneven air velocities and entering air temperature changes over the heat exchangers. The improvements of combining two heat exchangers into one unit are presented, along with the effect on the total system.
The paper also discusses improvements in manufacturing relating to reduction in cost of the combination unit, as well as the concept of combining an air-conditioning evaporator and cab heater.
