Application of tube sheets in microchannel heat exchangers

Tube sheets are a core component of microchannel heat exchangers. They fix the tube bundles and separate the flow channels, enabling efficient distribution and sealing of the refrigerant within the flat tubes, significantly improving heat exchange efficiency.

The tube sheets are made of corrosion-resistant materials (such as titanium alloy or duplex stainless steel) to withstand high-temperature and high-pressure conditions. Precision welding processes ensure structural stability and extend equipment lifespan.

Optimized tube sheet design (such as tapered gradient structures) reduces fluid resistance. Combined with intelligent flow control valves, it precisely controls refrigerant flow, meeting energy-saving requirements.
