The invention discloses a cooling water circulation system of an outboard engine. The cooling water circulation system comprises a cold water flowing part, a hot water flowing part and a water-gas mixed flowing part, the cold water flowing part comprises a water inlet structure, the water inlet structure comprises a main water channel and an auxiliary water channel for simultaneously feeding water, the included angle between the extension direction of the auxiliary water channel and the extension direction of the main water channel is an acute angle, and the main water channel and the auxiliary water channel are respectively connected with a water pump assembly for pressurizing; fluid firstly flows through the cold water flowing part, then flows through the hot water flowing part and the water-gas mixed flowing part to be cooled, and is discharged from an outlet of the water-gas mixed flowing part. According to the outboard engine cooling water circulation system, water enters through the main water channel and the auxiliary water channel, and the problem that water cannot enter the main water channel due to blockage is effectively solved.

    本发明公开了一种舷外机冷却水循环系统,包括冷水流动部、热水流动部和水气混合流动部;冷水流动部包括进水结构,所述进水结构包括同时进水的主水道和副水道,所述副水道的延伸方向与主水道的延伸方向的夹角呈锐角,所述主水道和副水道分别与用于加压的水泵组件连接;流体先流过冷水流动部,流经热水流动部和水气混合流动部降温冷却,由水气混合流动部的出口排出。本发明提供了一种舷外机冷却水循环系统,通过主、副水道进水,有效解决了主水道被堵塞无法进水的困境。
