To provide a heat exchanger cooling device which can suppress an excessive use of a dedicated pump for sending water in a main tank to a water discharge part while suppressing a number of pumps by sufficiently using the water in the main tank.SOLUTION: A first pump 50 for sending water to a water discharge part 32 is arranged at a first flow passage 40 for connecting a first flow-out port 34A of a main tank 34 and a water discharge port 32. Also, a flow-in port 34B of the main tank 34 and the water discharge part 32 are connected to each other by a second flow passage 42, and a second flow-out port 34C of the main tank 34 and a flow-out port 36A of a sub-tank 36 are connected to each other by a third flow passage 44. A second pump 52 for sending water to the second flow passage 42 side is arranged at a connecting flow passage 46 for connecting the second flow passage 42 and the third flow passage 44 to each other. A first three-way valve 54 is arranged at a connecting part between the connecting flow passage 46 and the second flow passage 42, and a second three-way valve 56 is arranged at a connecting part between the third flow passage 44 and the connecting flow passage 46.SELECTED DRAWING: Figure 1
【課題】メインタンク内の水を充分に用いつつポンプの数を抑えながら、メインタンク内の水を水吐出部に送る専用ポンプの過剰な使用を抑えることができる熱交換器冷却装置を得る。【解決手段】メインタンク34の第一流出口34Aと水吐出部32とを接続する第一流路40には、水吐出部32に水を送る第一ポンプ50が設けられる。また、メインタンク34の流入口34Bと水吐出部32とを第二流路42が接続し、メインタンク34の第二流出口34Cとサブタンク36の流出口36Aとを第三流路44が接続する。第二流路42と第三流路44とを接続する連結流路46には、第二流路42の側に水を送る第二ポンプ52が設けられる。連結流路46と第二流路42との接続部には第一の三方弁54が設けられ、第三流路44と連結流路46との接続部には第二の三方弁56が設けられる。【選択図】図1
