<P>PROBLEM TO BE SOLVED: To provide a cooling device of an automatic vending machine for satisfactorily reducing power consumption. <P>SOLUTION: A cooling device 10 of an automatic vending machine includes a refrigerant circuit 20 configured by successively connecting an evaporator 24, a compressor 21, a condenser 22, and an expansion mechanism 23 via refrigerant piping 25 to cool a cold storage material stored in a storage container 26 by using the evaporator 24 as a cold heat source by circulating a sealed refrigerant, in which a merchandise storage area 2a for storing merchandise in a merchandise storage cabinet 2 having a heat insulating structure is cooled by using the cooled cold storage material. The cooling device 10 includes: a condensation part 31 thermally connected to the cold storage material; an evaporation part 32 arranged at a heat radiation site 2b on the upper side of the merchandise storage area 2a in the merchandise storage cabinet 2; and heat transfer means 30 that transfers the cold heat of the cold storage material to the heat radiation site 2b by circulating working fluid sealed between the condensation part 31 and the evaporation part 32 through phase change. <P>COPYRIGHT: (C)2013,JPO&INPIT |
