Description
Изобретение относитс к теплотехник и может быть использовано в теплообмен- йых аппаратах, а также в конденсаторах и игспарител х холодильных машин.The invention relates to heat engineering and can be used in heat exchangers, as well as in condensers and igniters of refrigerating machines.
Цель изобретени - интенсификаци теплообмена.The purpose of the invention is to intensify heat transfer.
На изображена теплообменна труба, поперечный разрезi на фиг.2 - то же, продольньй разрез.Figure 2 shows a heat exchange tube, the cross-section in figure 2 is the same, longitudinal section.
Теплообменна труба имеет в попе- речном сечении лепестковый профиль 1 и изогнута по длине по винтовой линии 2, котора имеет угол подъема 45-135. Лепестки выполнены в форме эпициклоид с удлиненным основанием, Труба снабжена снаружи оребрением 3.The heat exchange tube has a petal profile 1 in cross section and is curved in length along a helical line 2, which has an elevation angle of 45-135. The petals are made in the form of an epicycloid with an elongated base, the pipe is provided with fins on the outside 3.
Скоростной поток теплоносител , проход по трубе,, контактирует с поверхностью трубы и отдает или забирает от нее тепло, причем, за счет спиралевидной поверхности, образованной стенками эпициклоидного профил 1 трубы, поток теплоносител центробежной силой прижимаетс к поверхности трубы и значительно улучшает процесс теплообмена. Затем тепло передаетс через стеики трубы к контактирующему с внешней поверхностью трубы наружному поперечному пластинчатому оребрению 3, которое отдает тепло внешней среде .The flow velocity of the coolant, the passage through the pipe, contacts the surface of the pipe and releases or takes heat from it, moreover, due to the spiral-shaped surface formed by the walls of the epicycloid profile 1 of the pipe, the flow of heat-transfer agent is centrifugally pressed to the surface of the pipe and significantly improves the heat exchange process. Heat is then transferred through the pipe steaks to the outer transverse plate fin 3, which contacts the external surface of the pipe, which gives off heat to the external environment.
