چکیده
Compressed air is widely used in enterprises, and it possible to reduce consumption on pneumatic devices by heating. Most often, heating carried out shell-and-tube heat exchangers. To increase the area of exchange between medium air, finned tubes are used, which can significantly volume occupied heater. The design heater influenced many factors, importance influence each them differ significantly. It advisable use overall characteristic form a compactness factor, shows ratio heater.
 work developed method for determining optimal heaters such parameter as factor. obtained regression equations make determine factors number rows across flow length one tube exchanger According Fisher's criterion, model adequate true dependence with confidence level 95%. all, affected transverse flow. Changing does not fundamentally affect values output parameters. With an their flow, achieve highest coefficient, main has pronounced maximum.
 Using technique, possible, fairly simple formulation, analyze value factor various combinations above optimize
