Heat exchange device

Abstract

In a heat exchange device, a plate-shaped tube ( 4 ) in which a plurality of channels ( 10 ) through which a first or second thermal medium ( 2 ), ( 3 ) flows are formed is disposed in a thermal storage material ( 5 ) that exchanges heat with the first or second thermal medium ( 2 ), ( 3 ), and the plate-shaped tube ( 4 ) is formed by joining two plates into a laminated form. Each plate has a plurality of elongated projections ( 8 A, 9 A) that protrude away from the mating faces of the plates and have hollows formed therein, and a plurality of flat portions ( 8 B, 9 B) between the projections. Openings of the hollows formed in one of the plates are closed by the corresponding flat portions of the other plate so that the hollows provide the channels.

1 . A heat exchange device characterized by comprising:
 a plate-shaped tube in which a plurality of channels through which a first thermal medium or a second thermal medium flows are formed; and   a thermal storage material that exchanges heat with the first thermal medium or the second thermal medium, wherein   the plate-shaped tube is disposed in the thermal storage material;   the plate-shaped tube is formed by joining two plates into a laminated form;   each of the plates has a plurality of elongated projections that protrude in a direction opposite to mating faces of the plates and have respective hollows formed therein, and a plurality of flat portions located between the elongated projections; and   openings of the hollows formed in one of the two plates are closed by the corresponding flat portions of the other plate so that the hollows provide said plurality of channels.   
     
     
         2 . A heat exchange device characterized by comprising:
 a plate-shaped tube in which a plurality of channels through which a first thermal medium or a second thermal medium flows are formed; and   a thermal storage material that exchanges heat with the first thermal medium or the second thermal medium, wherein   the plate-shaped tube is disposed in the thermal storage material;   the plate-shaped tube is formed by joining two plates into a laminated form;   each of the plates has a plurality of elongated projections that protrude in a direction opposite to mating faces of the plates and have respective hollows formed therein, and a plurality of flat portions located between the elongated projections; and   openings of the hollows formed in one of the two plates face those of the hollows formed in the other plate, so that the hollows defined by the elongated protrusions of the two plates provide said plurality of channels.   
     
     
         3 . A heat exchange device according to  claim 1  or  2 , wherein
 a plurality of plate-shaped tubes each comprising said plate-shaped tube are arranged in parallel with each other at predetermined intervals: 
 the thermal storage material fills space between the plate-shaped tubes, and comprises a thermal storage material that fuses when heated and coagulates when cooled; and 
 the plate-shaped tubes are arranged such that the elongated projections of one of the plate-shaped tubes are opposed to the flat portions of an adjacent one of the plate-shaped tubes which is located adjacent to said one of the plate-shaped tubes. 
 
     
     
         4 . A heat exchange device according to  claim 3 , wherein
 said plurality of plate-shaped tubes comprise first plate-shaped tubes through which the first thermal medium flows and second plate-shaped tubes through which the second thermal medium flows.   
     
     
         5 . A heat exchange device according to  claim 4 , wherein
 at least one of the first plate-shaped tubes and at least one of the second plate-shaped tubes are adjacent each other.   
     
     
         6 . A heat exchange device according to any one of  claims 3  to  5 , wherein
 the elongated projections of said one of the plate-shaped tubes have outside faces that are inclined relative to the flat portions of said adjacent one of the plate-shaped tubes. 
 
     
     
         7 . A heat exchange device according to  claim 1 , wherein
 each of the elongated projections of one of the two plates is shaped like a triangle in cross section, and the corresponding flat portion of the other plate provides a bottom of the triangle.
