The invention discloses a rotational flow parking heater with a preheating structure, and relates to the technical field of parking heaters, the rotational flow parking heater comprises a combustion heating cylinder, a rotational flow diffuser is mounted at the end of the combustion heating cylinder, and an oil gas importer is mounted on the outer edge surface of the rotational flow diffuser; a preheater installed on the surface of the outer edge of the rotational flow diffuser is arranged on one side of the oil gas importer. According to the rotational flow parking heater with the preheating structure, air and fuel are guided into the rotational flow diffuser through the oil gas importer to be mixed, combustion heating is carried out in the combustion heating cylinder, and then hot air is exhausted in cooperation with the hot air exhaust pipe; waste gas rich in heat is guided to the preheater through the waste gas exhaust pipe to heat the rotational flow diffuser and the oil-gas mixture in the rotational flow diffuser so as to increase the temperature of the oil-gas mixture before the oil-gas mixture enters the combustion heating cylinder, and therefore the guided-in air and fuel oil are preheated, and the combustion efficiency is improved.
本发明公开了一种具备预热结构的旋流驻车加热器,本发明涉及驻车加热器技术领域,包括燃烧加热筒,所述燃烧加热筒的端部安装有旋流扩散器,所述旋流扩散器的外缘表面上安装有油气导入器,所述油气导入器的一侧设置有安装在旋流扩散器外缘表面上的预热器。该具备预热结构的旋流驻车加热器,通过油气导入器将空气和燃料导送入旋流扩散器对其进行混合,并在燃烧加热筒中进行燃烧加热,再配合热空气排出管将热空气排出,利用废气排出管将富含热量的废气导送至预热器对旋流扩散器及其中的油气混合物进行加热,以提高油气混合物进入燃烧加热筒前的温度,从而对导入的空气及燃油进行预热,提高燃烧效率。
