TECHNICAL FIELD

The present invention relates to a work machine.

The application claims priority to Japanese Patent Application No. 2018-035512, filed on Feb. 28, 2018 to Japan, the contents of which are incorporated herein by reference.

BACKGROUND TECHNOLOGY

Patent Document 1 discloses a work machine equipped with a cooling device. The cooling device is provided in a cover of the work machine. The cooling device includes a fan, and a radiator, an oil cooler, and an inter-cooler serving as cooling units for receiving air by the fan. These cooling units are obliquely arranged in parallel so that end portion of each of the cooling units overlaps each other when viewed from an opening formed in the cover.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

In order to improve cooling performance by the cooling units, it is necessary to secure a cooling area, which is an area to receive air, while suppressing ventilation resistance and securing a flow rate of air. On the other hand, if a plurality of cooling units are inadvertently arranged, the installation space increases thereby resulting in an increase in the size of the work machine itself.

The present invention is provided in view of such a problem and the object thereof is to provide a work machine capable of improving cooling performance while achieving compactness.

Means for Solving the Problem

An aspect of the present invention provides a work machine including: a work machine main body in which a main flow path extending in one direction by a first wall surface and a second wall surface opposed to each other is defined; a fan for allowing air to flow along a flow path direction which is a direction in which the main flow path extends; a first cooling unit that protrudes from the first wall surface so as to be perpendicular to the flow path direction and defines a first opening portion between the first cooling unit and the second wall surface, at a first position in the flow path direction of the main flow path; a second cooling unit that protrudes from the second wall surface so as to be perpendicular to the flow path direction and defines a second opening portion between the first wall surface and the second cooling unit along with partially overlapping the first cooling unit when viewed from the flow path direction, at a second position downstream of the first position in the flow path direction of the main flow path; and a partition member that is provided across an end portion of the first cooling unit on the second wall surface side and an end portion of the second cooling unit on the first wall surface side, and defines a first section flow path having the first cooling unit as an inlet and the second opening portion as an outlet, and a second section flow path having the first opening portion as an inlet and the second cooling unit as an outlet.

Effect of Invention

According to the work machine of the present invention, cooling performance can be improved while reducing in size is achieved.
