Abstract
A cooler is placed on a power module to cool the power module with refrigerant through a refrigerant pipe, and includes a heat transfer plate having a groove into which a cooling pipe is fitted, and a presser plate configured to press the cooling pipe against the groove. The cooler includes a hinge mechanism configured to rotatably attach the presser plate to the heat transfer plate such that the presser plate is switched between an open position at which the groove is exposed and a closed position at which the presser plate covers the groove.
Claims10
A cooler for cooling a heat generating component with refrigerant flowing through a refrigerant pipe, the cooler comprising:
- a heat transfer member having a groove into which the refrigerant pipe is fitted, and
- a presser plate configured to directly press the refrigerant pipe against the groove, the presser plate being rotatably attached to the heat transfer member such that the presser plate switches between an open position at which the groove is exposed and a closed position at which the presser plate covers the groove,
- a lock mechanism configured to prevent rotation of the presser plate to keep the presser plate in the closed position,
- a rotary protrusion piece protruding from an end portion of the presser plate near an axis of rotation of the presser plate, and
- a rotation supporter provided on one side of the heat transfer member in a direction of the groove width to engage the rotary protrusion piece and rotatably support the rotary protrusion piece,
- wherein the presser plate is large enough to cover the entire groove when closed.
