FIELD: engine building.
SUBSTANCE: invention can be used in internal combustion engines. Air cooler of supercharging air in internal combustion engine (1) includes heat exchanger (5), fan (7), supply (11) and discharge (13) pipelines and inlet header (3). Cooling ribs are made on intake manifold housing and supply pipelines. Intake manifold and its supply pipelines are arranged in casing (6). Casing is made in the form of a cavity with an outlet flared end (10) and inlet nozzle (12) by means of which the casing cavity is connected to the supplying pressure cone (9). Heat exchanger is mounted in the base of the pressure cone, and on its opposite side diffuser (8) with a delivery fan is installed. Fan has electric drive with electronic control unit of its engine speed.
EFFECT: technical result consists in improvement of engine operation by reducing temperature of supercharging air and its constant in different temperature conditions.
