Filed: 2005-05-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cylindrical heat exchanger comprising a simple heat insulating structure for preventing the occurrence of troubles such as the fracture and corrosion of a generating tube caused by the intrusion and freezing of water around the generating tube.  <P>SOLUTION: This cylindrical heat exchanger comprises a hollow cylindrical tube 2, the generating tube 3 wound to the outer periphery of the cylindrical tube 2 for circulating and supplying a refrigerant inside thereof, and a heat insulating material 14 attached to the outer peripheral face of the cylindrical tube 2 on which the generating tube 3 is placed in a state of covering the generating tube 3. The heat insulating material is an elastic thermoplastic resin. As the elastic thermoplastic resin is used as the heat insulating material 14 for resin foam, water absorption can be prevented though it is found on the resin foam, and thus moisture is not stored and frozen around the generating tube. Further as the heat insulating material has elasticity, the heat exchanges can follow thermal expansion/contraction even if the cylindrical tube 2 is deformed by the change of a temperature, thus a clearance is hardly formed, and a high water stopping effect can be achieved.  <P>COPYRIGHT: (C)2007,JPO&INPIT
