PROBLEM TO BE SOLVED: To provide a device for forming minute air bubbles in a liquid to make the liquid to generate heat and a technique to which the feature for raising the temperature of the liquid is added as a value added.SOLUTION: In the use state of the device, suction pressure is at least once set to a strong suction state. That is, low pressure of a numerical value exceeding 110% is set with respect to suction low pressure at the time of rated operation of a vortex flow pump. The thermodynamical energy possessed themselves by minute bubbles, which are repeatedly circulated by suction/discharge is made easy to release in adiabatic compression and atmospheric release.COPYRIGHT: (C)2011,JPO&INPIT【課題】液体中に微小気泡を生成して液体を発熱させる装置の提供であって、付加価値として、液体の温度をたかめるという特徴を付加した技術である。【解決手段】装置の使用状態において、吸引圧力を少なくとも1回、強い吸引状態となす。すなわち、渦流ポンプの定格運転時における吸引低圧に対して110%を超える数値の低圧とする。そのことで、断熱圧縮、大気解放を吸引・吐出で繰り返し循環する微小泡が自ら有する熱力学的エネルギーを解放しやすくする。【選択図】 図3
