Novel liquid cooling motorcycle cooler

Abstract

The invention relates to a novel liquid cooling motorcycle cooler which comprises a liquid cooler and an engine oil cooler, wherein the liquid cooler comprises an externally-built liquid cooling heat radiator, a cooling liquid inlet, a cooling liquid outlet and a cooling liquid pump, wherein the cooling liquid inlet is connected with the upper end of an engine water jacket; the cooling liquid outlet is connected with the lower end of the engine water jacket; the water jacket, the cooling liquid outlet, the cooling liquid pump, the liquid cooling heat radiator and the cooling liquid inlet are connected sequentially in circulation; an engine oil cooler comprises an externally-built oil radiator, an oil outlet and an oil inlet, wherein the oil outlet is connected with an oil pump opening in an engine crankcase; the oil inlet is connected with the bottom of the engine crankcase; and the engine oil in the crankcase flows through the oil pump, reaches an oil radiator through the oil outlet, and reaches the crankcase through the oil inlet. By adopting the liquid cooling motorcycle cooler provided by the technical scheme, the whole engine is promoted to be cooled, machine elements are prevented from being deformed abnormally due to nonuniform cold and hot, which is much better for the normal operation of the engine.

Description

technical field [0001] The invention relates to a cooler, in particular to a novel liquid-cooled motorcycle cooler. Background technique [0002] At present, whether it is a four-stroke or two-stroke motorcycle engine, the combustion temperature is very high when it is working under high load. Especially for three-wheeled motorcycles, it is often in a high-load state. The gas temperature in the combustion chamber is as high as 1900 ° C ~ 2000 ° C The temperature of parts in contact with high-temperature gas, such as cylinder block, cylinder head, piston, valve, and upper part of cylinder wall, is about 600 °C. These parts absorb a large amount of heat. If they are not cooled properly in time, the parts will expand due to heat, making the original gap smaller, and the lubricating oil film cannot be established, resulting in a series of serious failures such as machine parts being stuck, which is not conducive to the engine. normal operation. At present, the cooling methods ...

These parts absorb a large amount of heat. If they are not cooled properly in time, the parts will expand due to heat, making the original gap smaller, and the lubricating oil film cannot be established, resulting in a series of serious failures such as machine parts being stuck, which is not conducive to the engine. normal operation

At present, the cooling methods used by motorcycles mainly include air cooling and liquid cooling. Air cooling includes natural air cooling and forced air cooling. Among them, natural air cooling has simple structure, light weight and low cost, but the cooling effect is related to wind direction and wind speed. When the car is running at low gear and low speed, especially when the tricycle is running at low speed and heavy load (such as continuous driving on a large slope or mountain road, etc.), due to the high engine speed and low vehicle speed, the natural wind when the vehicle is running cannot drive the engine The heat is taken away in time, and the cooling effect is poor, which is not conducive to the normal operation of the engine; on this basis, there is also forced air cooling, which is mainly used in some models where the engine is hidden in the car body and cannot be used naturally. Therefore, the shroud is reasonably arranged around the cylinder block and the cylinder head, and then a cooling fan is installed to force the introduction of natural wind to cool the outside of the engine. The effect is not affected by the speed of the vehicle, but there is a problem that when the cooling fan stirs the air circulation, its running noise increases the engine noise accordingly, especially when a high-power fan is installed, the noise is very loud, and the cooling effect of the air cooling is still not good. It is ideal, but it is still not conducive to the normal operation of the engine.

Furthermore, it is the liquid cooling method of the liquid-cooled motorcycle involved in the patent of the present invention. The engine cylinder of the liquid-cooled motorcycle is provided with an engine water jacket. To the engine water jacket and cooling pipes, the excess heat of the engine is brought to the radiator to dissipate. The liquid cooling system has nothing to do with the wind direction and wind speed. Even when the motorcycle is idling or running at low speed, the cooling system also has sufficient heat dissipation capacity. The engine noise is also low, but the current liquid cooling parts are concentrated around the cylinder block, which cannot cool the lubricating oil in the engine at the same time, and the upper part of the engine piston is usually cooled by the oil sprayed from the crankshaft bearing, but due to The lubricating oil in the crankcase is sealed and does not dissipate heat, and the temperature of the oil will rise after the engine runs for a period of time. In this way, the temperature of each part of the engine will still not match, and the engine cannot be cooled well. effect, which is not conducive to the normal operation of the engine
