FIELD: heating.SUBSTANCE: invention relates to the field of heat engineering and may be used in heat exchangers, in which heat transfer is carried out via fixed and rotary walls similarly to a pipe-in-pipe type or built into an engine unit. In the liquid-oil heat exchanger for internal combustion engines of vehicles, comprising a body, in which there is a pipe rigidly connected with it with an inner pipe, installed as capable of rotation, the inner pipe at the inlet and outlet is equipped with pump blades, and via a sealant it is connected with an electric motor, besides, on the inner pipe there is a helical ribbing, and ribs have dissections and are turned at the angle from 10° to 45°.EFFECT: higher level of stability of oil temperature and high level of thermal equivalents of coolants at most severe modes of internal combustion engine operation, which do not depend on number of crankshaft rotation.1 dwg |
