FIELD: heating.SUBSTANCE: in the method to cool two flows of coolant by means of heat exchange with a cooling air via a heat exchange surface in a multiturn cross heat exchanger, both flows are cooled in a single bisectional matrix of a heat exchanger, at the same time the coolant flow having higher inlet temperature is previously cooled in the first section of the matrix, using temperature potential of outgoing cooling air flow. Then, being mixed with the main coolant flow, varying its inlet temperature and increasing temperature discharge, it arrives into the second section of the matrix, where both flows continue to be cooled to the necessary temperature with an incoming air flow at higher temperature discharge.EFFECT: increased efficiency of a heat exchanger and reduced hydraulic resistance of an air tract.8 dwg |
