Extender engine cooling water cavity structure

Abstract

The invention relates to a structure of a cooling water chamber for a range extender engine, which includes a cold water chamber and a cylinder liner arranged in the cold water chamber; a water inlet and a water outlet window are arranged on the cold water chamber, and the outer side of the water outlet window is also arranged along the edge of the window There are sealing grooves for installing sealing parts; inner cooling fins are arranged on the side wall of the cylinder liner; outer cooling fins are also arranged on the outer surface of the cold water chamber. The cooling water chamber structure of the range extender engine according to the present invention is adopted, and the inner cooling fin is installed inside the cylinder body, which effectively increases the heat dissipation area, and at the same time increases the water storage volume of the cold water chamber, so that the cooling water can be taken away from the cylinder body More heat can effectively reduce the operating temperature of the engine and increase the service life of the engine.

Description

technical field [0001] The invention belongs to the field of range extender engines, in particular to a cooling water chamber structure for a range extender engine. Background technique [0002] A range extender usually refers to a kinetic energy device that can provide additional electric energy to help electric vehicles or electric equipment extend the running time. Ordinary range extenders are usually composed of an engine and a generator; the engine part of the range extender is different from the The fuel engine used alone is especially limited by the volume and weight and the use environment. The range extender engine generally has a small displacement and low power, which is different from ordinary fuel engines in structure and function. The water channel of the cylinder body of the water-cooled engine currently on the market is a spiral water channel. There is no heat dissipation structure in the water channel, and it is only a water flow channel. Therefore, the co...

Problems solved by technology

The water channel of the cylinder body of the water-cooled engine currently on the market is a spiral water channel. There is no heat dissipation structure in the water channel, and it is only a water flow channel. Therefore, the contact area between the cooling water and the cylinder block is very small, and the heat taken away by the cooling water from the cylinder block is small. Too much, making it difficult for the engine to cool down during operation, and the overall service life of the engine is reduced
