This paper investigated the effect of four different fan matrix configurations on the air-side flow-field and water-side heat exchange performance of a radiator. With the introduction of fan matrix configurations, the wake region behind bumper beam is enlarged, and the vortex pair breaks up much rapidly, thus enhancing the turbulence intensity of wake. The vorticity reaches the minimum level under the fan matrix N = 6, which could reduce the energy loss of the airflow upstream of radiator. The fan matrix configuration can increase the velocity uniformity of the airflow passing through the radiator, especially for the fan matrix N = 6. Furthermore, due to the fan matrix N = 6 achieves the maximum heat dissipation uniformity of radiator, and it also achieves the best heat exchange performance. Consequently, to achieve the maximum cooling air mass flow rate and heat exchange performance, it should carry out an optimization process during the design phase of fan matrix.

This study establishes a thermal management model to improve the heat exchange performance and uniformity of the flow-field distribution in the engine compartment of a wheel loader. Flow-field analyses are performed for an XG956 wheel loader in a virtual wind tunnel using the combined engine compartment thermal management model and computational fluid dynamics. The Fluent calculations revealed various problems. For example, the inlet flow rate at both sides of the engine compartment is small, which accounts for about 8.5% of the total flow, and the flow uniformity of radiator becomes worse with the increase in the air flow. The original cooling system is improved based on the simulation results and then verified by field testing. A comparison of the test data with the simulations indicates that the values obtained using the thermal management model of the engine compartment are largely in agreement with the experimental values, with a maximum deviation of the heat transfer rate at the rated speed of 5.1%. The research method presented in this article could further help to increase the productivity of the non-road mobile machinery cooling system and lower design costs. The temperature of pressurized air, hydraulic oil, transmission oil, and engine cooling fluid decreased by 22.5%, 8.7%, 2.2%, and 8.4% in the improved loader, respectively.

We study heat exchangers at the experimental setup aiming at the energy-saving. The feature of this heat exchange process is of the fact that the working medium is a porous metal. The pores are filled with freon and operation of the refrigeration unit condenser is studied. The scheme of the experimental setup and experiment methodology are given. The results of the experiment and its processing are also presented.
