HEAT EXCHANGER AND AUTOMATIC VENDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a heat exchanger and an automatic vending machine for improving heat exchange efficiency with simple configurations.

SOLUTION: In an in-left cabinet heat exchanger 24c configured such that when a supplied low pressure refrigerant in a gas/liquid two phase state passes a self-low pressure refrigerant passage 2411, the heat exchange of the low pressure refrigerant with air passing its own periphery is carried out via a corrugate fin 247 to cool the air, and that when a supplied high pressure refrigerant in a single-phase state passes a self-high pressure refrigerant passage 2441, the heat exchange of the high pressure refrigerant with the air passing its own periphery is carried out via the corrugate fin 247 to heat the air, the high pressure refrigerant passage 2441 is arranged at the upper stream side of the flow of air than the low pressure refrigerant passage 2411. It is desired that the refrigerant is carbon dioxide.
