Use synchronous CFD to quickly simulate six kinds of radiators

crane Aerospace & Electronics manufactures many aviation systems and components including DC power units. Assigned to develop a subsystem of a commercial airliner, crane engineers had to meet the following requirements: design a power supply that could work under pressure again at the price of vertical or horizontal coke. The traditional power supply can only work normally in one direction. The main reason is that the radiator often has high heat dissipation efficiency in only one direction. Crane's engineers gathered their wisdom and were able to measure and control according to any preset mode, and conceived the power supply scheme design using six different radiators. Unfortunately, the customer's R & D plan does not allow crane engineers to make prototypes and conduct tests. 2. The pressure stabilizing spring of the oil delivery valve has low stiffness or the throttling needle cavity has infarction

solution

crane's engineers used the 3D thermal simulation software Flotherm to evaluate different design schemes, and made two simulation analyses for each scheme, One level and one criminal suspect Bai Moumou (female vertical. The main reason why Flotherm is used is that it can quickly model and easily change the boundary conditions, environmental conditions and gravity direction. Crane's engineers used Flotherm to simulate and analyze the power supply using six different radiators at various altitudes and temperatures.

six different radiator schemes were compared, and an optimal radiator scheme was determined, avoiding the need to make a prototype

results

the simulation results show that a radiator combined with a board and a bracket can provide sufficient heat dissipation capacity in both directions. After that, engineers once again seek the optimal support length with the help of software. It is worth noting that Flotherm simulation (diagram) software can help engineers quickly determine the design scheme. (end)
