PROBLEM TO BE SOLVED: To suppress a decrease in an air side heat transfer rate and to suppress a decrease in a cooling capability of a heat conveying circuit in the circuit for conveying the air or the like, in a refrigerator used for an air forcibly circulating type cooling equipment such as a cold storage cabinet, a refrigerator with a deep freezer or the like to communicate a heat between the refrigerant and the fluid such as the air. SOLUTION: Louvers 8 are provided at a surface of fins 7 of a heat exchanger with the fins so that an opening 9 becomes substantially perpendicular to the air flowing toward the exchanger 6 from a wall 5 by the air flowing through a bypass air duct 5. Thus, since a temperature boundary layer is most effectively updated while suppressing an increase in a ventilating resistance, and a heat transfer rate of the air side can be improved, a decrease in the cooling capability of the heat conveying circuit can be suppressed.
