Abstract

A drive system includes a first drive unit, a second drive unit, and a fan, which are arranged in a row along a first direction. The first drive unit includes a first cooling passage communicating with a first inlet and a first outlet, and extending along the first direction. The second drive unit includes a second cooling passage communicating with a second inlet and a second outlet, and extending along the first direction. The fan sucks in a refrigerant flowing out from the first outlet and blow the refrigerant in a direction intersecting the first direction, thereby causing the refrigerant to flow through the first cooling passage, and suck in the refrigerant in the direction intersecting the first direction and blow the refrigerant toward the second inlet, thereby causing the refrigerant to flow through the second cooling passage.

Dependent claims

A drive system comprising a first drive unit, a second drive unit, and a fan,

wherein the first drive unit, the fan, and the second drive unit are arranged in this order and in a row along a first direction from the first drive unit to the second drive unit,
the first drive unit includes a first cooling passage extending along the first direction and having a first inlet formed on a side opposite to the fan and a first outlet formed on a side of the fan,
the second drive unit includes a second cooling passage extending along the first direction and having a second inlet formed on the side of the fan and a second outlet formed on the side opposite to the fan, and
the fan is configured to:
suck in a refrigerant flowing out from the first outlet and blow the refrigerant in a direction intersecting the first direction, thereby causing the refrigerant to flow through the first cooling passage;
and
suck in the refrigerant in the direction intersecting the first direction and blow the refrigerant toward the second inlet, thereby causing the refrigerant to flow through the second cooling passage.
