２には出口管８が接続されている。 That is, as shown in FIGS. 1 and 2, each stage of panels P 1 , except the lower header 3 of the final stage panel-shaped heat transfer means (hereinafter simply referred to as panel) P o
The interior of the lower header 3 of P 2 ... is divided into three chambers, a central chamber 3b and both side chambers 3a, 3c, by two partition plates 6, and the both side chambers 3a, 3c are used for the lower header 3 of the next stage, respectively. It is communicated with the central chamber 3b through a communication pipe 5. However, only the chambers 3a and 3c on both sides of the lower header 3 of the panel in the stage before the final stage are communicated with the undivided lower header 3 of the panel P o in the final stage through the connecting pipe 5. And the first panel
An inlet pipe 7 is connected to the central chamber 3b of the lower header 3 of P 1 , and an outlet pipe 8 is connected to the upper header 2 of the final panel P o .

b, rises through the central heat exchanger tube 4, flows into the upper header 2, descends through the heat exchanger tubes 4 on both sides, and flows into the chambers 3a, 3c on both sides of the lower header 3. Lower pipe header 3 of this first stage panel P 1
The fluid flowing into the side chambers 3a, 3c then flows through the connecting pipe 5 to the central chamber 3b of the lower header 3 of the panel P2 of the next stage, that is, the second stage,
Here, the same cycle as in the first stage panel P1 is used, and the same cycle is followed in the third stage, fourth stage, and so on. The fluid that has flowed into the chambers 3a and 3c on both sides of the lower header 3 of the panel in the stage before the final stage passes through the connecting pipe 5 to the panel in the final stage.
It flows into the undivided lower header 3 of P o , rises through the heat exchanger tubes 4, flows into the upper header 2 and then flows through the outlet pipe 8 to other systems.

い。 Although the embodiment in which the lower header of each stage except the final stage is partitioned into three chambers has been described above, the present invention is not limited to this and may be partitioned into two chambers.
In other words, the inside of the lower header of each stage except the final stage is
One of the two chambers is connected to the other of the two chambers of the lower header of the next stage by a connecting pipe, and the lower header of the lower header of the stage before the final stage is Only one of the two chambers is connected to the undivided lower header of the final stage through a connecting pipe, and the inlet pipe is connected to the other of the two chambers of the lower header of the first stage. In addition, an outlet pipe may be connected to the upper header of the final stage.
