Thermal and hydraulic analysis of a high flux heat exchanger
- Oklahoma State Univ., Stillwater, OK (United States). School of Mechanical and Aerospace Engineering
With new navigation and high powered radar equipment requiring numerous data processing units, today`s military aircraft is experiencing an increase in dependence on electronics. Furthermore, modern technology is constantly creating electronic chips that are capable of more power without increasing the surface area, thereby causing larger heat fluxes. Due to the combination of these factors, new techniques need to be developed for the heat removal of the electronic components. One such technique is the High Flux Heat Exchanger, HFHE, developed by McDonnell Douglas. The concern of this paper is to summarize the analysis of the performance, both hydraulically and thermally, of the HFHE throughout the steady state operation of the electronic components. Because the HFHE contains 20 CHICs in parallel, each CHIC performs independently. Therefore, the heat transfer tests can be performed for one CHIC at a time. The tests matrix was constructed by varying the flow rate through the HFHE from 60 to 240 kg/hr by an increment of 15 kg/hr; the coolant temperature of the PAO entering the HFHE from {minus}10 to 40 C by an increment of 10 C; and the heat load applied from 0 to 100 W by an increment of 20 W. Using these results allows for the estimation of the parameters needed for the electronic coolant system using the HFHE. These parameters include the pump size and flow rate needed for sufficient thermal performance of the HFHE.
