PROBLEM TO BE SOLVED: To provide a cooling/heating apparatus of a vending machine for maintaining excellent heat exchange efficiency while arranging a cooling heat exchanger and a warming heat exchanger in series with respect to the direction of air flow in an article housing part. SOLUTION: The cooling heat exchanger 4A having fins arranged at wide pitches and the warming heat exchanger 19 having fins arranged at narrow pitches are respectively arranged in the article housing part of the vending machine. The respective fins are provided in series along the direction of air flow, and the fins of the cooling heat exchanger 4A and the fins of the warming heat exchanger 19 are partially integrally arranged. Disturbance of air flow is eliminated or reduced at a boundary part between an area where the cooling heat exchanger 4A is provided and an area where the warming heat exchanger 19 is provided. Consequently, reduction in a flow rate is suppressed, and reduction in heat exchange efficiency are suppressed. COPYRIGHT: (C)2009,JPO&INPIT
