Description

Cooling system for straddle vehicles

The present invention relates to a heat dissipation system for a straddle vehicle, in particular to a heat dissipation mechanism configuration that takes away heat energy generated by an engine through air flow heat exchange.

The motorcycle is one of the common means of transportation in daily life. When the rider turns the throttle handle to ride, the throttle wire connected to the throttle handle will drive the valve opening of the throttle valve body of the fuel supply system to supply fuel, so that the engine unit starts. to generate power.

Since the ignition and explosion of the engine unit will generate heat, which will cause the temperature of the engine to rise, therefore, the locomotive must be equipped with a cooling system to maintain the engine at an appropriate operating temperature. Common cooling methods are roughly classified into air cooling, water cooling and oil according to different media. Cold and so on.

Among them, most of the straddle vehicles with non-air-cooled heat dissipation methods usually set the water tank under the frame, between the left and right frames, or any position behind the front wheels. The surface is sprayed on the blade surface of the water tank heat exchanger, which makes the heat dissipation blades of the heat exchanger easy to be dirty, resulting in a smaller heat dissipation area, which in turn makes the cooling efficiency worse.

The main purpose of the present invention is to provide a heat dissipation system for a straddle vehicle. By arranging the two radiators in specific areas on both sides of the steering tube, the radiator can be easily installed, and the ventilation effect of air flowing through the radiator is better. And can increase the windward area of the radiator to strengthen the heat dissipation function.

In order to achieve the aforementioned object, the heat dissipation system of the present invention comprises: a frame with a frame head pipe assembled with a steering tube, a lower triangle seat and an upper triangle connected to a steering handle seat are respectively installed at the bottom and the top of the steering tube. seat; and a plurality of radiators, respectively located on opposite sides of the frame head pipe to connect the frame, the top ends of the radiators are located below the steering handle seat, and the bottom ends of the radiators are lower than the lower triangle the lower edge of the seat, and a leading edge spacing distance and a trailing edge spacing distance are formed between the radiators; wherein, the leading edge spacing distance is greater than the rear edge spacing distance, so that the radiators face a side of the straddle vehicle The front and rear direction lines are arranged obliquely.

In a possible embodiment, a first included angle and a second included angle are respectively formed between the heat sinks and the front-rear direction line, and the angle of the first included angle is different from the angle of the second included angle. In another possible embodiment, the heat sinks are arranged in a mirror-symmetrical arrangement on the front-rear direction line.

In addition, the rear ends of the radiators are substantially aligned with a centerline of the frame head pipe; a front body of the straddle vehicle is configured with an air inlet, and the position of the air inlet is aligned with a windward side of the radiators.

Furthermore, the distance between the rear edges is greater than the distance between two opposite ends of a rotation path constructed by the lower triangle seat, so that the lower triangle seat will not touch the radiators located on both sides when the steering tube is rotated. .

To sum up, in the present invention, a plurality of radiators are placed opposite to the position below the steering handle seat on both sides of the steering tube, and the length of the radiators extends downward beyond the lower edge of the lower triangular seat, so that the airflow passes through the radiator. The ventilation effect is provided, and the increase of the windward area of the radiator can greatly improve the cooling effect of the engine.
