The present invention relates to a direct-cooling type ice maker having a channel structure, and more particularly, to a direct-cooling type ice maker having a channel structure in which a refrigerant flows along an outer circumferential surface of an inner member through a refrigerant channel portion formed to be surrounded by an outer circumferential surface of an inner member, To a direct cooling type freezing device having a flow path structure in which refrigerant heat is directly transmitted to ice water to be cooled.

2. Description of the Related Art Generally, an ice maker is an apparatus for producing ice as refrigerant is moved to an ice-making tube by a pressure of a compressor and heat-exchanged through a condenser.

The conventional ice maker comprises a machine room for installing a compressor, a condenser, a condensing fan, and the like required to perform a refrigeration cycle, and an ice storage room for storing ice cubes. The ice storage room is provided with an ice- And an ice making chamber in which an ice guide plate for discharging ice, a plurality of spray nozzles for spraying water to the ice-making frame, and a water storage tank for storing water necessary for ice-making are formed.

Here, in the conventional ice maker, the outer circumferential surface of the ice-making frame is made to be in close contact with the evaporator in an indirect manner.

This indirect method is disadvantageous in that the heat of the evaporator is indirectly transferred without being directly transmitted to the ice-making frame, and the heat of the evaporator is lost even when the ice-making frame and the evaporator are brought into close contact with each other. there was.

As the ice-making time becomes longer, the operation time of the ice-making cycle becomes longer, resulting in power loss and inconvenience that the ice is not smoothly supplied to the user.
