Abstract
To improve a cooling performance of a cooler applied to a semiconductor device.SOLUTION: A cooler (2) includes: a top plate (200) forming a flat first surface (201) in a coolant flow path (250); a bottom plate (220) forming a second surface (261) facing the first surface in the coolant flow path; and a plurality of protrusion parts (262) erected from a second surface of the bottom plate toward the first surface. The plurality of protrusion parts are provided such that another protrusion is disposed at a position translated by a first distance (P2) in a first direction substantially parallel to a second direction from an upstream to a downstream in the flow path of the coolant and by a second distance (P1 / 2) in a direction orthogonal to the first direction, and the second surface of the bottom plate is formed in a waveform in which an apexes (263) of a convex part and an apexes (264) of a concave part alternately appear in the first direction and each of the apexes of the convex part and each of the apexes of the concave part extend in the second direction.SELECTED DRAWING: Figure 5
