Alternate absorbing core of staggered horizontal tube bundles and ripple screen mesh layer

The invention discloses an alternate absorbing core of staggered horizontal tube bundles and ripple screen mesh layers. The ripple screen mesh layers are inserted among horizontal tube bundles of the staggered horizontal tube bundles; the cross-section shapes of the ripple screen mesh layers are in a trapezoidal wave shape, and the adjacent ripple screen mesh layers are symmetrical relative to the clamped horizontal tube bundles; the upper edge and lower edge of the ripple screen mesh layer trapezoidal wave are respectively arranged on the lower part of an upper-layer heat transferring tube and the upper part of a lower-layer heat transferring tube of the ripple screen mesh layer trapezoidal wave; the folding line direction of the ripple screen mesh layer trapezoidal wave and the direction of the heat transferring tubes are the same; the ripple pitch of the trapezoidal wave is equal to the horizontal tube center distance of each horizontal tube bundle; a formed liquid membrane orderly passes through an alternate caloric transmitting structure of the horizontal tube bundles and the ripple screen mesh layers. The alternate absorbing core has the advantages that the absorbing area of the absorbing core is enlarged, furthermore the solution mixing is promoted, and the solution surface is kept continuing relatively strong in absorbing driving power, so that en effect that a reinforced solution absorbs cryogen steam is realized.
