The invention provides a propelling device, a heat dissipation control method of the propelling device and water area movable equipment. The propelling device comprises a water avoiding part provided with a working cavity; the motor is contained in the working cavity and used for outputting rotating torque capable of forming propelling power; the wading part is fixedly connected with the water avoiding part, the wading part is provided with a liquid storage cavity and a backflow channel communicated with the liquid storage cavity and the working cavity, the liquid storage cavity is provided with cooling liquid, and the cooling liquid can exchange heat with external water through the wading part; and the transmission assembly is connected to the water avoiding part and the wading part and used for conveying part of the cooling liquid in the liquid storage cavity to the working cavity and guiding the cooling liquid to flow back to the liquid storage cavity through the backflow channel after making contact with the motor. Wherein the cooling liquid can be in direct contact with the motor in the propelling device for thermal coupling, so that the negative influence of temperature gradient on the heat dissipation efficiency of the motor is reduced, and the heat dissipation efficiency is greatly improved. The cooling liquid thermally coupled with the motor is transferred into the wading part to be thermally coupled with the external environment through the wading part, and the cooling circulation process is fast and efficient.

    本申请提推进装置、推进装置的散热控制方法及水域可移动设备。推进装置包括:避水部,设有工作腔;电机,收容于工作腔,用于输出可形成推进动力的转动扭矩;涉水部,与避水部固定连接,涉水部设有储液腔,以及连通储液腔和工作腔的回流通道,储液腔设有冷却液,冷却液可经涉水部与外界的水热交换;传输组件,连接于避水部和涉水部,用于将储液腔内的部分冷却液输送至工作腔,并引导冷却液与电机接触后经回流通道流回至储液腔。其中,冷却液可直接与推进装置中的电机接触进行热耦合,降低了“温度梯度”对电机散热效率的负面影响,大幅提升了散热效率。与电机热耦合的冷却液转移至涉水部中通过涉水部与外部环境进行热耦合,冷却循环过程快捷高效。
