Embodiment Construction

[0027] A number of preferred embodiments of the present invention are described below with reference to the figures in the description, so as to make the technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned herein.

[0028] to combine figure 1 , figure 2 , image 3 and Figure 4 Explain the cooling method of the rotor of the air-cooled Wankel engine. In order to prevent the rotor temperature from being too high, the rotor is provided with three cooling chambers. Cooling air channel 2b and front cylinder head cooling air outlet 2c, at this time the rotor is just at the bottom dead center position (such as Figure 4 position shown), the cooling air takes away a large amount of heat through the rotor cooling chamber, and then the rotor cooling chamber passes through the rear cylinder head cooling air inlet ...

Abstract

The invention relates to a Wankel engine rotor with an efficient heat dissipation function, and belongs to the field of rotor engines. The Wankel engine rotor comprises a Wankel engine rotor body and further comprises fins, wherein the fins are arranged on a cooling cavity of the rotor, and each fin is an arc with the circle center passing through the center of the rotor. The heat exchange area can be increased by adopting the properly arranged enhanced heat exchange fins in a rotor cooling cavity; the external heat dissipation capability of the rotor can be favorably improved; the thermal load and thermal stress of the rotor are reduced; and the service lives of the rotor and parts of the rotor are prolonged.

Description

technical field [0001] The invention designs a high-efficiency heat dissipation Wankel engine rotor, which belongs to the field of rotor engines. Background technique [0002] The Wankel engine is another high-efficiency internal combustion engine besides the reciprocating piston engine. The Wankel engine has the advantages of simple structure, high power-to-weight ratio, and easy miniaturization, which can meet the urgent needs of electric vehicle range extenders. Therefore, the Wankel engine can be applied to an extended-range electric vehicle. In addition, in terms of military applications, the Wankel engine is favored in the research and development of lightweight, miniaturized, and highly mobile equipment because of its own advantages. It is very suitable for new types of drones, self-propelled weapons, and military robots. Cutting-edge equipment demands power units. [0003] The main structure of Wankel engine includes triangular rotor, cylinder block, front and rear...
