LIQUID COOLING SYSTEM OF COMBUSTION ENGINE

摘要

A liquid cooling system of combustion engine has a radiator with collectors for supply and discharge of cooling liquid and surrounding tubes installed between the collectors and equipped with ribs, and axial blower placed in plane parallel to front of radiator. The ribs are fixed on the tubes with spacing that increases in direction of blower axis, and cooling tubes are arranged with spacing that increases in direction of blower axis. The radiator has hermetic system of flat tubes the upper part of which is placed between the cooling tubes. In the lower part of the system flat tubes are connected to each other, and the lower section is lowered to collector for discharge of cooling liquid and is partially filled with heat carrier boiling temperature of which is 2- higher than optimal temperature of cooling liquid.
