上記排気入側部のピッチ(L2)と同じである。As shown in FIG. 2, the plate fins (7) on the high temperature exhaust passage (4) side of the heat pipe (6) are two types of plate fins having different lengths in the exhaust flow direction, that is, the front-back direction.
It is composed of fins (7A, 7B). And between the long plate fins (7A), the short plate fins (7A)
B) are arranged one by one near the exhaust outlet side. Each plate fin (7A, 7B) is a heat pipe by hydraulic expansion.
It is attached in close contact with (6). However, the short plate fin (7B) is not attached to the heat pipe (6) on the exhaust side. As a result, the pitch (L1) (3.2 mm; 8 sheets / inch) at the exhaust outlet side of the plate fins (7A, 7B) on the high temperature exhaust passage (4) side becomes equal to the pitch (L2) at the exhaust inlet side. The size is twice as large as (1.6 mm; 16 sheets / inch). When the pitch of the exhaust outlet side is made larger than that of the exhaust inlet side, it is manufactured in exactly the same way as the conventional device except that two types of plate fins are used by configuring as described above. Therefore, there is also an advantage that the manufacturing is easy and no extra cost is required. On the other hand, the plate fins (7) on the low temperature air supply passageway (5) side of the heat pipe (6) are composed of long plate fins (7A) only, and their pitch is the pitch of the exhaust inlet side ( Same as L2).

Is used by being installed, for example, in the ceiling of a storage room, and has the following effects. That is, indoor air warmed by a heating device or the like is discharged from the exhaust inlet (14) through the high temperature exhaust passage (4) to the outdoor from the exhaust outlet (8), while cold outdoor air is supplied. It is supplied indoors from the inlet (9) through the low temperature air supply passage (5) and the air supply outlet (13). At that time, the heat of the exhaust gas passing through the exhaust passage (4) is transferred to the plate fins.
(7) or directly to the heat pipe (6), the heat of the working fluid evaporates and the heat is transferred to the low temperature air supply passage (5) side part of the heat pipe (6), and directly or from the plate part. Heat is transferred to the air supply through the fins (7). As a result, the supply air is heated and supplied indoors, so that the indoor temperature does not drop.

On the surface of (7), water contained in the exhaust gas condenses to generate drainage. Normally, this drain drops due to its own weight and enters the drain pan (15) and is discharged from the drain pipe (16) .However, if the supply air temperature drops extremely during the severe winter season, the surface temperature will decrease. The drain freezes on the exhaust side of the plate fin (7) on the side of the hottest exhaust passage (4), which is the lowest. However, as described above, the exhaust outlet side pitch (L1)
However, since it is made twice as large as the pitch (L2) of the exhaust inlet side, the time until the plate fins (7) are closed due to the generation of bridges due to freezing of the drain,
As a result, the number of bridge removing operations is reduced, and the ventilation resistance due to the freezing of the drain is also reduced.
