To facilitate attachment of evaporation pipes to a refrigerating device.

The refrigerating device includes a heat insulating case body having an inner case including boundary portions between both side plates and a back plate formed to have a curved surface, an outer case and a heat insulating material between both cases; a heat insulating door; a first refrigerant circuit; and a second refrigerant circuit. A first evaporation pipe of the first refrigerant circuit is attached to the outer sides of a top plate, both side plates, the back plate and a bottom plate so as to meander on the outer side of the top plate of the inner case from the upstream side where a first refrigerant is made to flow in the first refrigerant circuit toward the downstream side, meander on the outer sides of both the side plates and back plate in the width between both the side plates and back plate from the upper side to the lower side, and further meander on the outer side of the bottom plate of the inner case. A second evaporation pipe of the second refrigerant circuit is attached to the outer sides of the top plate, both the side plates, the back plate and the bottom plate so as to meander on the outer side of the top plate from the upstream side where a second refrigerant is made to flow in the second refrigerant circuit toward the downstream side without being overlapped with the first evaporation pipe, meander on the outer sides of both the side plates and back plate in the width between both the side plates and back plate from the upper side to the lower side, and further meander the outer side of the bottom plate.
