转子发动机的合理冷却,已成为提高转子发动机使用寿命的关键问题之一。由于转子发动机各个工作过程发生在缸体内部的特定区域里,因而就形成了所谓“热弧区”和“冷弧区”。在“热弧区”部位,缸体型面和前后缸盖、中隔板受到燃烧气体的连续加热,而“冷弧区”部位又不断的受到新鲜混合气的冲刷,这就使转子发动机在工作时缸体、缸盖和中隔板各部位热负荷差异很大。如果冷却水流路设计不能与各部位热负荷情况相适应,冷却强弱 Reasonable cooling of the rotor engine has become one of the key issues to improve the service life of the rotor engine. Since the working process of the rotor engine takes place in a specific area inside the cylinder, so-called “hot arc zone” and “cold arc zone” are formed. In the “hot arc zone” part, the cylinder block surface and front and rear cylinder head, the partition plate by the combustion gas continuous heating, and “cold arc zone” parts are constantly subject to fresh air mixture, which makes the rotor engine in Working cylinder, cylinder head and diaphragm in various parts of the heat load varies widely. If the cooling water flow path design can not adapt to the various parts of the heat load, cooling strength
