COOLING APPARATUS FOR A HEAT-GENERATING ELEMENT

摘要

A cooling apparatus for a heat-generating element includes: a heat sink on which the heat-generating element is mounted; a cooling component having a recess, the cooling component and the heat sink being faced and joined to each other so that the recess forms a coolant passage; and a sealing member provided between the heat sink and the cooling component so as to seal the coolant passage and separate an interior and exterior of the coolant passage. A first distance is longer than a second distance with regard to a distance between facing surfaces of the heat sink and the cooling component near the sealing member, the first distance being between the facing surfaces at an interior side of the coolant passage separated by the sealing member, and the second distance is a distance between the facing surfaces at an exterior side of the coolant passage separated by the sealing member.

1. A cooling apparatus for a heat-generating element, comprising:
a heat sink having a main surface on which the heat-generating element is mounted and a heat radiation surface from which heat generated by the heat-generating element is radiated; a cooling component having a recess, the cooling component and the heat sink facing and joining each other so that the recess forms a coolant passage in which a coolant flows; and a sealing member provided between the heat sink and the cooling component so as to seal the coolant passage and separate an interior and exterior of the coolant passage, wherein the sealing member is provided outside a plane which is coplanar with a first sidewall of the recess, a first distance is longer than a second distance with regard to a distance between facing surfaces of the heat sink and the cooling component near the sealing member, the first distance is a distance between the facing surfaces at an interior side of the coolant passage separated by the sealing member, and the second distance is a distance between the facing surfaces at an exterior side of the coolant passage separated by the sealing member.
