HEATING HIGH-DUTY HEAT EXCHANGER FOR AUTOMOBILES, AS WELL AS HEATING-CONDITIONING DEVICE WITH HEATING HIGH-DUTY HEAT EXCHANGER

摘要

FIELD: heating.;SUBSTANCE: heating high-duty heat exchanger includes soldered heat transfer matrix consisting of flat tubes located on the side of cooling device and ribs located on air side and consisting of many slots located one after the other in air flow direction and creating turbulence and streamlined with heating air. At that, heat transfer matrix has such volume V-Matrix of matrix that centre-to-centre distance t-Rippe between ribs located on air side, as well as such centre-to-centre distance t-Rohr between flat tubes for cooling device that specific volume V-Spec of heat exchanger formed of them and calculated as per formula V-Spec=V-Matrix/(t-Rohr+(4*t-Rippe)) exceeds low limit value of 0.140 m².;EFFECT: creation of heating heat exchanger providing the required power at reduction of manufacturing cost and fuel consumption.;33 cl, 21 dwg
