Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, in particular to a high-efficiency heat dissipation device for an outboard motor. Background Art

[0002] An outboard motor is an engine installed on the outside of the hull for propulsion. The engine generates heat during operation, which will affect the engine's operating efficiency. If the engine is not cooled in a short period of time during long-term use, it will cause internal heat and shorten its life.

[0003] The existing outboard motor heat dissipation device has a water cooling method. The water cooling system introduces water from the outside through a water pump, dissipates the heat of the engine into the water through the heat dissipation effect of the heat exchanger, and then pumps the hot water out to circulate. This method causes great water pollution. The utility model adopts a fan cooling method to dissipate the heat of the engine, and a waterproof device is also designed in the heat dissipation device. It is small in size and easy to disassemble. For this reason, we propose an efficient heat dissipation device for outboard motors. For this reason, we propose an efficient heat dissipation device for outboard motors. Utility Model Content
