Heat Exchanger Design Optimization Using Mathematical Modeling Methods for Selective Laser Sintering of Metal Powder

One of the key components of modern aircraft is a complex of airborne systems. A complex of on-board systems is a combination of interconnected systems, including a hydraulic system, an aircraft remote control system, an air conditioning system, etc., ensuring the performance of the aircraft's target functions. The complex of on-board systems includes many units that ensure reliable and trouble-free operation of the aircraft. For modern aircraft, helicopter and space technology, the issue of ensuring thermal balance is one of the main ones. Heat exchangers (HE) are widely used in the aviation and space industries. Such devices are used to ensure and maintain a given temperature regime by removing or supplying energy in relation to the working area. [1, 2] In general, a HE is a device for communicating energy from a heated coolant to a colder one. The effectiveness of HE depends on many factors, priority is:- heat transfer coefficient characterizing the proportion of transferred heat;- design features of the HE. To improve the characteristics of heat exchangers, technologies are actively developing to create highly efficient and reliable HE designs. The most optimal method of manufacturing the apparatus is laser sintering of a metal powder. Additive technologies allow you to produce parts directly from a computer file containing a 3D model. And this, in turn, provides flexibility that allows the rapid production of complex customized products and spare parts, which either cannot be manufactured using traditional production technologies or are required in small volumes.
