The invention relates to a natural aeration and constant temperature device for aquaculture, which includes a housing and a heat source machine disposed on a floating base. A first heat exchanger of the heat source machine is disposed between a first fan and a second fan. Formed below the second fan is an air-intake duct in which a water pipe array, a water evaporator, and a second heat exchanger are sequentially arranged from top to bottom. A mist chamber is formed under the floating base. The mist chamber collects outflow of water that is supplied by a first pump to the water pipe set, inflow of water sprayed outside the water pipe set by a second pump, and inflow of air generated through heat exchange so that a mixture of water and air generated through heat exchange occurring in the second heat exchanger is collected in the mist chamber and is then sprayed through injection nozzles thereof into an aquaculture field. Through detection performed by at least one sensor, a controller is allowed to control and adjust the operations of the above discussed components based on the detection to thereby realize energy saving, fast adjustment of water temperature to maintain in a constant temperature condition, and increasing dissolved oxygen content and thus increasing the survival rate of aquaculture.本發明係有關於一種水產養殖自然瀑氣恆溫裝置(一),其係於一浮座上方設有一殼體及一熱源機組,該熱源機組之第一熱交換器設於一第一風扇及第二風扇之間,且該第二風扇下方為一進風道,並依序由上而下設有一水管排、一水蒸發器、一第二熱交換器;該浮座底部下方更設有一水氣室,該水氣室係集收由第一水泵送入該水管排所排出之出水及由一第二水泵噴灑於該水管排外部之進水,以及熱交換後之進氣,使在該第二熱交換器熱交換後之水氣混合集注於該水氣室,再由其噴出口噴出進入水產養殖場,並藉至少一個以上之感測器的偵測,以供一控制器可根據偵測值調控上述各元件之作動,達到節能、快速調控水溫維持在恆溫狀態及提高其溶氧度,以增加水產養殖之存活率者。
