ともあつた。 However, such laminated heat exchangers have problems in terms of strength. In other words, when the heat exchange medium is gasified, the heat exchange medium flowing through the tube element applies internal pressure to the tube element in a direction that forces it to expand laterally. The tank part and flat tube part may be deformed in the bulging direction due to
There was a serious possibility that the molded plates would be separated and destroyed at the joints. Further, when an undesired external force is applied to the tube element in a direction that crushes it in the length direction or width direction, the tube element may easily bend or be crushed.

の連接縁部に形成される結露水排出口である。 That is, each molding plate 11 has a flat bulging part 11a for forming the flat tube part of the tube element in the middle part, and a bulging height for forming the tank part 4 of the tube element at both ends of the flat bulging part 11a. The bulge portion 11b having a relatively large diameter has a plurality of heat exchange medium circulation holes 11c along the width direction of the plate. Further, a flat joint surface 13 of a predetermined width is formed on the peripheral edge of the molded plate 11, and both side edges of the flat bulge portion 11a are connected to the joint surface 13.
A condensed water collecting groove 14 is formed by continuously bending the condensed water collecting groove 3 into a gutter shape, and a horizontal protruding edge 16 is formed continuously from the rising side wall 15 of the condensed water collecting groove. In addition, the swollen portion 11 of the molding plate 11
A vertically rising reinforcing ridge 17 that is continuous with the joint surface 13 is formed on the periphery b. This reinforcing ridge is formed by a force in a direction that causes the bond between the molded plates 11, 11 at the circumferential edge of the tank portion to separate, which is generated due to the flow pressure of the heat exchange medium flowing through the tank portion 4 in the completed state of the heat exchanger. However, it serves as a reinforcing rib to prevent this. Such a molded plate 11 is manufactured by press working. On the other hand, the intermediate plate 12 has an outer shape that follows the peripheral edge of the forming plate 11, and is formed so that only both side edges 12a, 12a in the width direction protrude outward from the edge of the joint surface 13 of the forming plate 11 in the joined state. It is set larger than the total width of the plate. On the other hand, in this invention, the intermediate plate 12 integrally has an inner fin portion 12b disposed on the flat tube portion 3 of the tube element 1 in order to increase heat exchange efficiency. That is, a large number of protrusions 12c are formed at the intermediate portion in the length direction with respect to the intermediate play. As shown in a partially enlarged view in FIG. 6, this protrusion 12c has an upwardly protruding cross-sectional part and a downwardly protruding cross-sectional part that are continuous in the width direction of the intermediate plate 12. They are formed so that they are arranged alternately, and are arranged alternately at predetermined distances in the length direction. Each of the protrusions 12c has a rectangular hole opening on both sides in the width direction of the intermediate plate 12, and the protrusion height is such that the top surface of each of the protrusions 12c substantially abuts the upper and lower forming plates 11 when the tube element 1 is in its complete state. It is set to be about. Further, at both ends of the intermediate plate 12 in the length direction, at positions corresponding to the heat exchange medium circulation holes 11c of the molded plate,
A plurality of heat exchange medium circulation holes 12d are respectively formed. The pair of upper and lower molded plates 11, 11 are integrated by brazing with the opening surfaces facing each other and the peripheral end of the intermediate plate 12 being interposed between the joint surfaces 13. A tube element 1 is configured. Therefore, as shown in FIGS. 1 and 4, the tube element 1 has condensed water collecting grooves 14 on both sides in the width direction, and corresponding rising side walls 15 of the condensed water collecting grooves 14 in the upper and lower molded plates. , 15, a side edge 12a of the intermediate plate 12 is formed to protrude into a recess 18, and an inner fin portion 12b is disposed on the flat tube portion 3 of the tube element. Incidentally, reference numeral 5 shown in FIG. 2 is a condensed water discharge port formed at the connecting edge between the tank portion 4 and the flat tube portion 3 of the tube element 1.

形することもない。 In the heat exchanger of the illustrated embodiment, the heat exchange medium supplied from the inlet pipe 9 enters the lowermost tube element from the inlet header 8 and flows through each tube element 1 up to the uppermost tube element. After exchanging heat with the air flowing in the direction of the arrow W through the air circulation gap including the outer fin 2 between the tube elements, the air is sent from the outlet header 8' to a compressor or the like (not shown) via the outlet pipe 9'. In this case, the heat exchange medium flowing through the tube element 1 is
The heat exchanger comes into contact with the upper and lower protrusions 12c of the inner fin portion 12b and flows while being significantly disturbed.As a result, the heat exchange efficiency is improved. On the other hand, inside the tube element 1, internal pressure is applied in the direction of expanding the tank part 4 and the flat tube part 3 laterally due to the heat exchange medium.
Since the intermediate plate 12 is interposed between the tube elements 1 and 1, the plate acts as a reinforcing material, reducing the possibility that the tube element 1 will deform in the bulging direction or that the joined portions of the molded plates will separate and break. Moreover, even if an external force is applied to the tube element, the tube element will not be easily bent or crushed. Furthermore, due to the presence of the upper and lower protrusions 12c of the inner fin portion 12b disposed on the flat tube portion 3 of the tube element 1, the flat tube portion 3 is deformed even if force in a compression direction is applied to the flat tube portion 3 from above and below. Not at all.

車室内側に飛来する現象を効果的に防止できる。 Further, during the above heat exchange, condensed water is generated from the circulating air, but the condensed water is pushed to the leeward side along the upper surface of the tube element 1 by the urging force of the circulating air, as shown by arrow A in FIG. 4. The condensed water flows directly into the condensed water collecting groove 14 and is discharged from the discharge port 5 to the outside of the heat exchanger. On the other hand, the condensed water accumulated on the side edge of the outer fin 2 and the condensed water overflowing from the collecting groove 14 is removed from the horizontal protruding edge 16 and the rising side edge 15 of the upper molding plate, as shown by arrow B in the figure. Flowing down along the outer surface, the side edge 1 of the intermediate plate 12
2b is the corresponding rising side wall 15 of the condensed water collecting groove 14,
15, the protruding side edge 12b acts as a deterrent plate that prevents the condensed water from flowing down, and a part of the condensed water received thereby is transferred to the protruding side. It flows along the edge toward the tank portion 4 of the tube element 1 and is discharged from the discharge port 5 to the outside of the heat exchanger. In this way, in this embodiment, the condensed water generated by heat exchange can be efficiently and reliably discharged to the outside of the vessel, and the so-called water splash, that is, the condensed water is directed to the leeward side by the urging force of the circulating air. It is possible to effectively prevent the phenomenon that the pushed tube element concentrates on the edge of the tube element, is further blown away by the circulating air, and flies into the interior of the vehicle.

The portions 12c' may be formed at intervals, or a portion of the intermediate plate may be cut upward and downward to form protruding portions.

優れた熱交換器となしうる。Effects of the Invention According to the present invention, a tube element is constructed by joining a pair of molded plates with the peripheral end of an intermediate plate having an inner fin section interposed between the joint surfaces of the peripheral edges thereof. That's what happens. Therefore, the intermediate plate acts as a reinforcing material against the internal pressure of the heat exchange medium in the direction of expanding the tube element laterally during heat exchange, and the external pressure in the direction of crushing the tube element in its length and width directions. The risk of separation of the bonding surfaces of the molded plates and the deformation and destruction of the tube elements can be reduced, and a heat exchanger with excellent pressure resistance and durability can be obtained.
