電子回路装置
Document Type and Number:
Japanese Patent JP7354004
Kind Code:
B2
Abstract:
This electronic circuit device is provided with: a circuit board having a wiring layer formed thereon; a conductor electrically connected to the wiring layer; a flow path former forming, together with the circuit board, a flow path for a refrigerant that flows in contact with the circuit board; a fastening member for fastening the circuit board and the conductor together; and a seal member for tightly sealing the flow path. The circuit board has formed therein a first through-hole penetrating therethrough between a cooling surface on which the flow path is formed and a back surface opposite to the cooling surface. The conductor has formed therein a second through-hole communicating with the first through-hole. The fastening member fastens the circuit board and the conductor together through the first through-hole and the second through-hole. As the fastening member fastens the circuit board and the conductor together, the seal member closes the first through-hole and the flow path is tightly sealed.
