Description

Heat dissipation system of straddle vehicle

The present invention relates to a heat dissipation system for a straddle-ridden vehicle, in particular to a heat dissipation mechanism configuration that takes away the heat generated by the engine through the heat exchange of the airflow.

Locomotives are one of the common means of transportation in daily life. When the rider turns the throttle handle to ride, the throttle cable 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 will start. To generate momentum.

Since the ignition and explosion of the engine unit will generate heat energy, which will cause the engine temperature to rise, the locomotive must be equipped with a cooling system to maintain the engine at an appropriate operating temperature. The common cooling methods are roughly divided into air cooling, water cooling and oil cooling according to different media. Three kinds of cold.

Among them, most straddle-riding vehicles with non-air-cooled heat dissipation methods usually have the water tank installed under the frame, between the left and right frames, or behind the front wheels. However, the sand rolled up by the front wheels during driving is easy to follow the wind. The surface is sprayed onto the blade surface of the water tank heat exchanger, which makes the radiating blades of the heat exchanger easy to get 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 straddle-ridden vehicles. By arranging two radiators in specific areas on both sides of the steering tube, the radiator is easy to install, and the ventilation effect of the airflow through the radiator is better. And can increase the windward area of the radiator to strengthen the heat dissipation function.

To achieve the foregoing objective, the heat dissipation system of the present invention includes: a frame with a frame head tube equipped with a steering tube, a lower triangle seat and an upper triangle connected to a steering handle seat are respectively installed on the bottom and 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 of the radiator is located below the steering handle seat, the bottom of the radiator is lower than the lower triangle The bottom edge of the seat, and a front edge separation distance and a rear edge separation distance are formed between the radiators; wherein the front edge separation distance is greater than the rear edge separation distance, so that the radiators face a side of the straddle vehicle The front and rear direction lines are arranged diagonally.

In a possible embodiment, a first included angle and a second included angle are formed between the heat sinks and the front-to-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 mirrored symmetrical arrangement with the front-to-back direction line.

In addition, the rear ends of the radiators are roughly aligned with a center line of the frame head pipe; a front shell of the straddle vehicle is configured with an air inlet, and the position of the air inlet is aligned with a windward surface of the radiators.

Furthermore, the distance of the trailing edge is greater than the movement distance of the two opposite ends of a rotation path constructed by the lower triangle seat, so that the lower triangle seat will not touch the heat sinks located on both sides when the steering tube rotates. Device.

In summary, the present invention places a plurality of radiators opposite to 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 triangle 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 efficiency of the engine.
