[0023] Specifically, the heat exchange box 1 is filled with clean water through the water inlet pipe 2, and then the hot air generated by the heating reaction of the epoxy resin in the reactor enters the curved tube 10 through the air inlet end 6. The hot air flowing in the curved tube 10 will transfer the heat to the clean water, and at the same time, the heat conducting plate 13 further conducts the heat to the hot water to improve the heat conduction effect. Finally, the gas without temperature is discharged outward through the air outlet end 7.

Finally, the heated clean water flows to the required equipment through the water outlet pipe 3. The purpose of this design is to conduct the heat in the hot air to the water to a certain extent through the curved tube 10 and the heat conducting plate 13, and to heat the clean water evenly through the synchronous and opposite rotation of the first screw rod 14 and the second screw rod 16 to ensure the use effect.

[0034] In summary: the heat exchange box 1 is filled with clean water through the water inlet pipe 2, and then the hot air generated by the heating reaction of the epoxy resin in the reactor enters the curved tube 10 through the air inlet end 6. The hot air flowing in the curved tube 10 will transfer the heat to the clean water, and at the same time, the heat conducting plate 13 further conducts the heat to the hot water to improve the heat conduction effect. Finally, the gas without temperature is discharged outward through the air outlet end 7. In this process, the first screw rod 14 and the second screw rod 16 rotate synchronously in opposite directions, pushing the clean water to circulate in a clockwise or counterclockwise direction, so that the clean water in the heat exchange box 1 is heated evenly and the temperature difference is reduced. Finally, the heated clean water flows to the required equipment through the water outlet pipe 3.
