1. Fixed Heat Exchanger Tubes: Numerous tube holes are evenly distributed on the tube sheet. The heat exchanger tubes are fixed in these holes through methods such as expansion joints and welding, ensuring that the heat exchanger tubes will not loosen or shift during operation.
2. Media Separation: The shell side and tube side of the heat exchanger are separated, allowing different media to flow in their respective spaces, thus achieving heat transfer.
3. Pressure Resistance: The heat exchanger withstands pressure from both the shell side and tube side, while simultaneously transferring the pressure to the supporting structure, ensuring the overall strength of the heat exchanger.
