High-efficiency Plate Condensers: A Comprehensive Analysis of Structure Principles and Application Fields

2025-11-01

I. Analysis of Core Structure A plate condenser is a heat exchange device based on the technology of stacking metal plates. Its core components include multiple layers of metal plates stamped into corrugated shapes, sealing gaskets, and a frame structure. These rectangular metal plates form cross-distributed fluid channels through a special corrugated design, enabling efficient heat exchange between hot and cold media in adjacent channels. The mainstream models use corrosion-resistant materials such as stainless steel and titanium alloy to make the plates, and the sealing system is composed of fluororubber or synthetic rubber, which can maintain stability under high-temperature and high-pressure environments. According to different assembly methods, plate condensers are divided into two types: removable frame type and fully welded brazed type. The former is convenient for cleaning and maintenance, while the latter is suitable for harsh working conditions. The corrugated shapes of the plates are mainly divided into herringbone, horizontal straight type, etc. By changing the arrangement and combination of the plates, parallel flow, counterflow, and multi-pass heat exchange modes can be achieved.
