An aerobic water vehicle comprising: a double floating body； a motor disposed between the double floating body and located at a top end of the double floating body； a driver disposed at a bottom end of the motor, and Electrically connecting the motor； and a dual impeller coupled to the motor, each impeller being located outside of each of the floating bodies. Because the drive is close to the water surface or partially immersed in water or fully immersed in water, the drive can achieve the heat dissipation effect of the drive and the motor by the flow of water and air driven by the impeller, or the drive is maintained at a constant temperature to prevent the drive. The overall temperature is too high to operate properly, which improves overall reliability.一種增氧水車，其包含有：雙浮體；一馬達，其係設於該雙浮體之間，並位於該雙浮體的頂端；一驅動器，其係設於該馬達的底端，並且電性連接該馬達；以及雙葉輪，其係耦接該馬達，各該葉輪係位於各該浮體的外側。因驅動器係接近水面或部分浸於水中或全部浸於水中，驅動器係可藉由葉輪所帶動的水流與空氣流，而達到驅動器與馬達的散熱效果，或者驅動器維持於一恆溫狀態，以防止驅動器因溫度過高造成無法正常運作，進而提升整體的可靠度。
