Wherein the steam inlet 2 is an inlet of a substance to be treated and is not an inlet of a condensing medium; likewise, the "condensate outlet 3" is the outlet for the substance to be treated, not for the condensing medium. For example, fig. 1 shows a condenser as an example, a steam inlet 2 is a steam inlet, and a condensate outlet 3 is a liquid outlet.
Referring to fig. 2 and 3, in a further embodiment, the flow guiding structure 4 includes a flow guiding inclined surface 41 located inside the casing 1 and guiding the liquid at the end of the casing 1 to the condensate outlet 3, the flow guiding inclined surface 41 is located between the condensate outlet 3 and the end of the casing 1 near the condensate outlet 3, and a lowest point of the flow guiding inclined surface 41 is opposite to the condensate outlet 3.
In this embodiment, the liquid accumulation region 0 is eliminated by providing the flow guiding inclined surface 41, and the liquid can be discharged from the flow guiding inclined surface 41 through the condensate outlet 3. Specifically, the specific inclination angle of the diversion inclined plane 41 can be designed according to actual conditions, and the requirement that the lowest point of the diversion inclined plane 41 is opposite to the condensate outlet 3 after the heat exchanger is installed is met.
