Abstract：
 A liquid-air-condenser belongs to thermal equipment technical fields. comprising steam inlet, heat exchange tube, fin, j cascade box, discharge pipe, three-limb tube, condensate outlet, single-pass pipe, shell; Steam from the steam inlet enter into the first cascade box and condense through the first group heat exchange tube, the vapor-liquid mixture flows into the second cascade box, vapor and liquid are separated: the liquid is ejected into the next cascade box by discharge pipes between cascade boxes , while steam enter into the next heat exchange tube group; collected by three-limb tube in the end and flow out through condensate outlet. The invention condense with stepped steam, separate by middle automatic vapor-liquid and drain fluid associate with super-cooling technology by the condensate concentrations, guarantee that each tube pass is entered with pure steam and cooled, effectively reduce the thickness of the liquid film in condensation process and eliminate the adverse biphasic flow pattern; compared with traditional condenser, save 30% material and reduce the condenser production and operation cost, and simple in production.
