PURPOSE:To obtain the titled apparatus by which the cooling of a foamable resin melt is performed intensively and uniformly, by extending a plurality of tubes in the direction crossing to the axis of a cylinder, making a cooling medium in a jacket to flow inside of the plurality of tubes and cooling the resin by the tubes from an interior. CONSTITUTION:A plurality of tubes 2 is attached in a cylinder 1 so as the tubes 2 to extend in the direction crossing to the axis of the cylinder 1 and penetrate the wall of the cylinder 1. A jacket structure is made by covering the outer face of the cylinder 1 with a cover plate 3 and the end of the tube 2 is opened 5 to the inside 4 of the jacket and the inlet 6 and outlet 7 of a cooling medium are provided to the cover plate 3 and a flange 8 is attached to both ends of the cylinder 1. |
