PROBLEM TO BE SOLVED: To improve heat transfer performance of a heat exchanger positioned in an air flow downstream side by using turbulence of a heat exchanger positioned in an air flow upstream side. SOLUTION: A perpendicularly cut and raised impact wall 12c is provided as a turbulence forming means for disturbing an air flow on at least a fin 12 of the heat exchanger 10 in the air flow upstream side of the plurality of heat exchangers 10 and 20 serially arranged in an air flowing direction.
