The invention relates to a multi-stage rotational flow combustion chamber system suitable for a parking heater, a fan assembly is fixedly mounted in a heater shell, the multi-stage rotational flow combustion chamber system comprises a heat exchanger which is fixedly mounted in the heater shell, and a part of the fan assembly is fixedly mounted in an air inlet end of the heat exchanger; the combustion chamber unit is fixedly mounted in the heat exchanger and communicates with the heat exchanger; the scavenging port assembly is fixedly mounted at the air inlet end of the combustion chamber unit; the oil pipe assembly is partially arranged on the peripheral side of the outer wall of the combustion chamber unit in a surrounding mode. The scavenging port assembly of the combustion chamber system comprises the first-stage scavenging port, the second-stage scavenging port and the third-stage scavenging port, and each scavenging port is composed of a plurality of blades, so that gas entering the first-stage scavenging port forms strong rotational flow wind, the rotational flow strength is enhanced through the second-stage scavenging port and the third-stage scavenging port, mixing of air and fuel is enhanced, and the combustion efficiency is improved. And sufficient combustion of fuel is guaranteed, the combustion efficiency is improved, meanwhile, formation of carbon deposition in the combustion chamber is reduced, and the service life of the heater is prolonged.

    本发明涉及一种适用于驻车加热器的多级旋流燃烧室系统,加热器壳体内固定安装风扇总成,包括:换热器,固定安装在加热器壳体内,换热器的进气端内固定安装风扇总成的部分;燃烧室单元,固定安装在换热器内,且与换热器连通;扫气口组件,固定安装在燃烧室单元的进气端;油管组件,油管组件的部分环绕设置在燃烧室单元外壁周侧。本燃烧室系统的扫气口组件包括一级扫气口、二级扫气口和三级扫气口,且每个扫气口均由若干叶片组成,使得进入一级扫气口的气体形成强旋流风,再经由二级扫气口和三级扫气口加强旋流强度,加强空气与燃料的混合,保证燃料充分燃烧,提高了燃烧效率,同时减少了燃烧室内积碳的形成,延长了加热器的使用寿命。
