熱交換容器１内で、熱交換面２側に、上下を区画する多孔質部材１９を取り付ける。多孔質部材１９の上側部分２２は、後述するように吸引手段６の液体エゼクタ１３と接続しているために低圧状態となっており、冷却水溜め部２０に溜まった冷却水が、多孔質部材１９を通って上側部分２２へ吸引される間に微細な水滴状となり、熱交換面２の下面に供給されるものである。 In the heat exchange container 1, the porous member 19 which divides up and down is attached to the heat exchange surface 2 side. The upper portion 22 of the porous member 19 is in a low pressure state because it is connected to the liquid ejector 13 of the suction means 6 as will be described later, and the cooling water accumulated in the cooling water reservoir 20 is the porous member. Fine water droplets are formed while being sucked into the upper portion 22 through 19 and supplied to the lower surface of the heat exchange surface 2.

熱交換面２を加熱する場合は、蒸気供給管３と制御弁７又は制御弁２１から熱交換容器１内へ所定量の蒸気を供給することによって、蒸気によって加熱される。加熱により蒸気の凝縮した復水は、熱交換容器１下端の分岐管２３からスチームトラップ４を通り、更に、液体エゼクタ１３から冷却水タンク１４へと至る。 When heating the heat exchange surface 2, the heat exchange surface 2 is heated by steam by supplying a predetermined amount of steam from the steam supply pipe 3 and the control valve 7 or the control valve 21 into the heat exchange container 1. Condensate condensed with steam by heating passes from the branch pipe 23 at the lower end of the heat exchange vessel 1 through the steam trap 4 and further from the liquid ejector 13 to the cooling water tank 14.
熱交換面２を冷却する場合は、冷却水供給管５の自動弁２７を開弁して冷却水溜め部２０へ冷却水を供給することによって、多孔質部材１９を通過する間に微細な水滴状となり、熱交換面２の下面から瞬時に滴下することがなく、熱交換面２の熱により冷却水が蒸発気化して、その蒸発線熱でもって冷却することで、冷却効率を向上することができる。 When the heat exchange surface 2 is cooled, fine water droplets pass through the porous member 19 by opening the automatic valve 27 of the cooling water supply pipe 5 and supplying cooling water to the cooling water reservoir 20. The cooling water evaporates by the heat of the heat exchange surface 2 and is cooled by the evaporation line heat without being dripped instantaneously from the lower surface of the heat exchange surface 2, thereby improving the cooling efficiency.
