The interaction of the coolant flow with the heated object is described mathematically, thermal and physical properties of the coolant and the design features of the devices that form the intensity of its heating are revealed. It is substantiated that in order to ensure minimum heat treatment time for the units with a low-temperature coolant, it is necessary to optimize the flow velocity in the gap clearance “guide device-unit wall” and the water flow for the formation of a mixed-type coolant.
