Abstract
To provide a cooler with good cooling efficiency. [Solution] The cooler comprises a control unit 221 positioned in a first direction for controlling the power supplied to the motor, a heat sink 224 which is a first holding part for holding the control unit, a protrusion 24E which is a second holding part for forming a flow path for cooling water, which is a heat transfer medium, between the first holding part and the protrusion 224E, a supply port which is a supply part formed on the upstream side in the first direction for supplying the heat transfer medium to the flow path, and an opening 24B which is a discharge part formed on the downstream side in the first direction for discharging the heat transfer medium from the flow path. The first holding part has a plurality of fins which are protrusions that protrude in a protruding direction toward the second holding part and, when viewed from the second holding part toward the first holding part, extend in the first direction and form a waveform with amplitude in a direction perpendicular to the first direction, and the second holding part has a plurality of peaks which are opposite to the protrusions and extend in the first direction and are formed to protrude toward the protrusions.
