Cooler

Abstract

A cooler (1) includes: a fin (20) having a coolant inflow port (110a); and a nozzle (10) configured to eject the supplied coolant toward the coolant inflow port (110a). The nozzle (10) includes a flow passage wall (13), a tip end (14), a pressure receiving portion (16) and a deformation portion (15). The tip end (14) provides a coolant supply hole (12) that ejects the coolant flowing through the flow passage. The pressure receiving portion (16) is configured to be provided between the flow passage wall (13) and the coolant supply hole (12), and to receive force in an ejection direction of the coolant. The deformation portion (15) is configured to be provided either of between the flow passage wall (13) and the pressure receiving portion (16) and in the pressure receiving portion (16), and to displace the coolant supply hole (12) in the ejection direction of the coolant in response to the force in the ejection direction of the coolant, the force being received by the pressure receiving portion (16).
