Abstract

Numerical and experimental studies were conducted to investigate the flow and heat transfer performance in different detached cooling modules with multiple types of heat exchangers, considering the typical dual heat exchangers in construction machinery cooling modules as examples. The porous media model was used to simulate the heat exchangers, and the multiple reference frame method was used to simulate fan performance. A numerical simulated model of vehicular cooling module was established and verified by experiment. On the basis of it, the numerical study of vehicular detached cooling modules was carried on. First, the detached cooling modules with serial structure were sat up, the influence of position and quantity of air intakes to cooling performance was studied. Then the detached cooling modules with non-serial structure were established, the influence of the position between heat exchangers (HEs) and fan was taken into account. The analysis showed that when the detached cooling modules were arranged in a tandem structure, the number of cooling air inlets was not effective for the performance improvement. When the same heat exchangers and fan were reconstructed in a non-series configuration, the performance improvement was significantly for the heat exchangers were relatively independent and wouldn’t interfere with each other. However, the requirements for the installation space were also severer. What’s more, the relative position between the heat exchangers also had an obvious influence on its performance. The dual heat exchanger non-series structure detached cooling module scheme had more advantages in performance than that in the single heat exchanger scheme or the tandem scheme, and had a higher cooling efficiency. Comparing to tandem cooling module, the detached cooling module can achieve the same heat dissipation at a lower fan speed, reduce the fan power consumption, and can achieve precise cooling on the basis of the controllable blinds installed at the heat exchanger inlet.
