To prevent cooling performance at an overcooling part due to the swallowing of high-temperature air or the like in a refrigerant condenser with the overcooling part.
An overcooling part 40 is arranged at the upper portion of a core part 23 of a refrigerant condenser 2, namely at the upper portion of a condensation part 39. As a result, even if a phenomenon occurs in that high- temperature air passing through the refrigerant condenser 2 and a radiator for cooling an engine passes the lower side of the refrigerant condenser and is swallowed up at the upstream side of the refrigerant condenser again on idling when a vehicle is waiting for a signal change, the high-temperature air cannot be suched in at the installation side of the overcooling part 40. Therefore, the cooling performance of the overcooling part 40 can be maintained appropriately even on idling.
