Abstract
A double pipe icemaker includes an inner pipe, and an outer pipe provided radially outside the inner pipe and coaxially with the inner pipe. The outer pipe allows a cooling target to flow in the inner pipe and a refrigerant to flow in a space between the inner and outer pipes. The outer pipe has a wall provided with at least one nozzle to jet the refrigerant into the space. The nozzle has a jet port. The jet port may allow the refrigerant to jet in a radial direction including at least an axial direction and a circumferential direction of the inner pipe. A shielding plate may be provided ahead of the jet port in a jetting direction such that the refrigerant hitting the shielding plate expands along a surface of the shielding plate in a radial direction.
