Abstract: A connection structure between a printed circuit board and a terminal block includes: an insertion portion at one end of the printed circuit board with a pattern disposed thereon; a terminal-block main body including a receiving port that receives the insertion portion; a nut held in the terminal-block main body; and a screw tightened into the nut. The pattern is interposed between the screw and the nut when the insertion portion is inserted into the receiving port.

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.

Abstract: A printed board on which a power module is mounted, a cooling pipe that is a refrigerant pipe of a refrigerant circuit, and a cooler attached to the power module and the cooling pipe are disposed in a casing. A support member by which the cooler is attached to the printed board and supported on the printed board, and a fixing member by which the printed board is fixed to the casing and supported on the casing are used.

Abstract: In a refrigeration apparatus, a main surface of a printed wiring board has a heavy electric region, which is a region in the lower part of the printed wiring board where a heavy electric component group is disposed, and a light electric region, which is a region positioned above the heavy electric region, where a light electric component group is disposed. A refrigerant jacket contacts a power device which is disposed in the heavy electric region. A liquid pipe of the refrigerant pipe includes a portion that extends upwards towards the refrigerant jacket, and a cooling portion contacts the refrigerant jacket.

Abstract: A facing surface of a refrigerant jacket includes a contact portion which contacts a device main body, a first recessed portion which faces a first lead section and secures an insulation distance to the first lead section due to being positioned further away from a power device than the contact portion, and a second recessed portion which faces the second lead section and secures an insulation distance to the second lead section due to being positioned further away from the power device than the contact portion.
