[0002] Existing shell-and-tube condensers suffer from problems such as low heat exchange efficiency, large size, and easy fouling. Although existing spiral wound tube heat exchangers have improved heat exchange efficiency by extending the flow channel, the traditional structure has problems such as flow dead zones caused by fixed tube spacing, condensate accumulation affecting heat exchange, and tube vibration and wear. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution:

[0004] A spiral wound tube heat exchanger for a condensation system includes a tube body with a front end cap at one end and a rear end cap at the other end. The front end cap is connected to a front flange, and the rear end cap is connected to a rear flange. Front through pipes are provided on both sides of the front end of the tube body. Fixing bolts, a central through pipe, and a side through pipe are provided on the front flange. The central through pipe is connected to the interior of the tube body. A tube body valve is provided on one side of the tube body. Metal discs are provided at both ends inside the tube body. Multiple spiral wound tubes are provided on the outer side of the metal discs. The side through pipes are connected to the interior of the multiple spiral wound tubes. Spiral metal plates are provided on the inner wall of the tube body and are connected to the multiple spiral wound tubes.

[0005] Preferably, an inner tube is provided inside the tube body, the front through-pipe is connected to the inside of the tube body, a groove is provided between the tube body and the inner tube body, and the groove is connected to the side through-pipe.

[0006] Preferred configuration: The front flange has several holes and is bolted to the front end cap; the rear flange has several holes and is bolted to the rear end cap.

[0007] Preferably, the metal disc is fitted and connected to the inner side of the inner tube, and multiple small holes are provided on the metal disc, and the spiral metal sheet is fixedly connected to the inner tube.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This invention improves heat exchange efficiency: the reverse winding and variable spacing design creates turbulence in the medium, increasing the heat transfer coefficient; it prevents scaling: the spiral fins and circular tube design reduce the stagnation zone and lower the scaling rate; it ensures structural stability: the flange support and corrugated spacers suppress tube bundle vibration; and it enables rapid condensate separation: improving gas-liquid separation efficiency.
