Problems solved by technology

[0004] However, in the conventional structure, a cylindrical oil cooler is arranged around the side wall of the cylinder, so the oil cooler protrudes and is bulky, leading to an increase in the size of the power unit.
In addition, since the oil cooler is arranged at the lower part of the crankcase, the distance between the oil pan and the oil cooler is shortened, and the oil cooler is affected by the oil temperature in the oil pan so that the temperature rises.

Abstract

The invention provides a cooling device of a power unit, capable of preventing an oil cooler from projecting. The cooling device comprises an oil cooler (105) and the oil cooler comprises: an oil path (108) for the oil supplied to an engine (20) as the power unit; a cooler cooling mechanism (109) for cooling the oil through the oil path (108), wherein the oil cooler (105) extends upwards along the axle of the cylinder (L1) and is formed into the plate shape at the side of the cylinder (22A).

Description

technical field [0001] The invention relates to a cooling device for a power unit. Background technique [0002] Patent Document 1 discloses a structure in which a cylindrical oil cooler (for example, Refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2003-314277 [0004] However, in the conventional structure, the cylindrical oil cooler is disposed around the cylinder side wall, so the oil cooler protrudes and is bulky, leading to an increase in the size of the power unit. In addition, since the oil cooler is arranged in the lower part of the crankcase, the distance between the oil pan and the oil cooler is shortened, and the temperature of the oil cooler rises due to the influence of the oil temperature in the oil pan. Contents of the invention [0005] The present invention was made in view of the above circumstances, and an object of the present invention is to provide a cooling device for a power unit capable of suppressing protr...
