下するという問題点があった。Conventional Technology This type of laminated heat exchanger, called a doron cup type, generally consists of a plate-like tube element (11) made up of two vessel-shaped molded plates facing each other, as shown in Fig. 5. Tank parts (13) (14) are stacked alternately through fins (12), and are bulged by the ends of the tube elements (11) above and below the vertical type, and on the left and right sides of the horizontal type. are formed, and a heat exchange medium inlet pipe (15) and an outlet pipe (16) are respectively connected to these tank parts (for example, Utility Model Publication No. 56-20766, Utility Model Publication No. 53-3238).
No. 0). However, as described above, since the heat exchange section has the tank sections (13) and (14) for storing the heat exchange medium at both ends, the area where air (A) circulates and acts effectively for heat exchange, that is, the effective heat The exchange area is the above tank part (13) (
14) There was a drawback of being limited in time. That is, as shown in Fig. 5, the presence of the tank parts (13) and (14) creates ineffective parts (X) (X) through which air does not flow, and the effective part (Y) of the heat exchanger becomes narrower. There was a problem that the heat exchange performance deteriorated.

前記問題点の完璧な解決にはならない。On the other hand, in the past, in order to solve this problem, by making a U-turn of the heat exchange medium within the tube element, the tank section was placed only at one end of the heat exchange section, and the effective heat exchange section was Proposals have also been made to expand the
Utsuko No. 53-32375). However, even in this case, the generation of an ineffective part due to the tank part is inevitable, and the above-mentioned problem cannot be completely solved.

。In this embodiment, the tube element (1) is constituted by a roll bond panel made of aluminum. That is, two aluminum plates are coated with an anti-crimping agent in a desired pattern, then overlapped and crimped, and the non-crimped portion is bulged by fluid pressure, thereby forming heat exchange medium passages along the pattern inside. (1a). (1b) is the crimped part on the periphery, (1C)
is the middle crimp part. Moreover, this tube element (1) has the above-mentioned one on one side edge located in the area through which air (A) for heat exchange flows, that is, one side edge on the air outflow side, as shown in FIG. A pair of heat exchange medium inlets and outlets (6) and (7) communicating with the heat exchange medium passage (1a) are formed in a bulge extending upwardly and downwardly so as to open on the side surface of the panel.

となっている。Therefore, the input header pipe (3) and the output header pipe (4)
) are arranged in parallel on the air outlet side of the tube elements (1) and (1) group, and are connected and integrated with the heat exchange medium inlets and outlets (6) and (7), respectively. (3a) and (4a) are communication holes bored in the peripheral walls of the header pipes (3) and (4). In addition, the header pipe (3
) and (4) are provided with partition plates (8) and (9) in order to change the flow direction of the heat exchanger medium for each predetermined number of tube elements and cause the medium to flow in a meandering manner. Accordingly, the heat exchange medium passage group is divided into three, thereby configuring a so-called three-bath type heat exchanger.

During this time, after exchanging heat with the air (A>) flowing between the tube elements (1) (1), it finally exits from the outlet header pipe (4) and is sent to, for example, a compressor (not shown).

ることができるものである。Here, in the above-described laminated heat exchanger according to the present invention, there is an inlet header pipe (3) and an outlet ladder pipe (4).
Since they are all made of tubular material, their presence will not obstruct the air flow, regardless of whether they are located within the air flow area. In addition, by providing the header pipe (3) < 4) on the outlet or inlet side of the air circulation area, the heat exchanger can be viewed in cross section perpendicular to the air flow direction, as shown in Figure 3. In this case, the fins (2) can be attached almost entirely between adjacent tube elements (1) (1), except for the crimp portion (1b) on the periphery. Therefore, the ineffective part (X) for heat exchange is the crimp part (1
b) is located in a very small portion of the upper and lower edges, e.g.
Only the 7m wide part can be used, and all other parts can be used as an effective part (Y) for heat exchange. Therefore, more than 90% of the total area in the cross section of the heat exchanger can be secured as an effective heat exchange area, whereas in conventional laminated heat exchangers, this is at most about 75 to 80%. However, this is a significant improvement, and a significant increase in heat exchange performance can be obtained.

そのセット時間を短縮しうろこと等の点で有利である。As is already clear from the above description, in the present invention, the inlet and outlet headers (3) and (4) are arranged either on the inlet side or the outlet side within the air flow area of the heat exchanger. It's okay to force me. However, it is not preferable to locate them at both ends of the heat exchanger because the flow resistance imparted to the air becomes large. In addition, although the illustrated embodiment shows a case where the tube element (1) is constructed of a roll bond panel, the tube element (1) is not limited to this, and by combining two molded plates as in the past, a heat exchange medium passage and a heat It is also possible to use one in which an exchange medium entrance/exit is formed. Furthermore, although the illustrated laminated heat exchanger is shown as a vertical type, it is of course also permissible to configure it as a horizontal type with the tube elements arranged horizontally. However, the use of roll bond panels allows the pattern of the heat exchange medium circulation circuit to be freely set, and the number of parts required for assembling the heat exchanger can be reduced.
It is advantageous in terms of shortening the setting time and reducing scales.

Since the header is installed in communication with the heat exchange medium inlet/outlet formed on one side edge of the tube element, the presence of the header limits the air circulation area, that is, the effective area for heat exchange. 90% or more of the total volume of the heat exchange section consisting of tube elements and fins can be used as an effective heat exchange section, greatly improving heat exchange performance. This has the effect of increasing the
