In the above arrangement, by arranging the condensation duct 20, the cooling water passing through the condensation duct 20 exchanges heat with the high-temperature and high-humidity steam in the air duct 11, so that the high-temperature and high-humidity steam is cooled and condensed rapidly, and the condensation effect of the condenser is improved. Compared with the mode of naturally cooling by utilizing the condensing sheet in the condenser in the related art, the condensing pipeline 20 can continuously provide cooling water to continuously cool the high-temperature high-humidity steam, and the problem that the condensing effect of the condenser is poor due to the fact that the temperature of the condensing sheet is increased after the heat exchange of the high-temperature high-humidity steam in the related art is avoided.

In addition, when the condensing duct 20 is a direct cooling duct, the space can be saved, so that the condenser can be made smaller, thereby saving the manufacturing cost of the condenser, and meanwhile, the condenser can be suitable for installation in a smaller space, thereby increasing the application range of the condenser. When the condensing pipe 20 is bent and cooled, the contact area of the condensing pipe with the steam with high temperature and high humidity can be increased, thereby enhancing the condensing effect of the condenser.

Example one

Specifically, in one embodiment, the condensing duct 20 and the air duct 11 have a volume ratio d, and d is greater than or equal to 0.2 and less than or equal to 0.5.
