There are many condensing methods used in the condenser, and one of them is that water is used as a cooling medium to exchange heat with the drying air, so that the moisture in the hot air is condensed and separated from the air. Such condensers usually have a channel-like body to which cooling water pipes are connected. The damp and hot drying air passes through the condenser body from bottom to top, and the cooling water flows out from top to bottom during the process of passing through the condenser body and exchanges heat with the damp and hot air. However, the condensing apparatus body has a limited space height due to space limitations, and the stroke of heat exchange between the hot and humid air and the cooling water is short.

With continued reference to fig. 6, the left side portion of the rear sidewall 219 of the hollow chamber 213 is provided with a first water cut groove 2193, the right side portion of the rear sidewall 219 is provided with a second water cut groove 2194, both the first water cut groove 2193 and the second water cut groove 2194 extend along the height direction of the hollow chamber 213, when the first airflow 5 flows through the first water cut groove 2193, water droplets carried by the first airflow 5 are intercepted by the first water cut groove 2193, so that the water droplets are separated from the first airflow 5, and the water droplets are prevented from flowing into the fan 3 along with the first airflow 5, and similarly, when the second airflow 6 flows through the second water cut groove 2194, water droplets carried by the second airflow 6 are intercepted by the second water cut groove 2194, so that the water droplets are separated from the second airflow 6, and the water droplets are prevented from flowing into the fan 3 along with the second airflow 6.

With continuing reference to fig. 3, 4 and 7, a water guiding groove 220 is disposed on the front side wall of the hollow chamber 213, the top end of the water guiding groove 220 is connected to the water outlet end of the cooling water pipe 22, and the bottom end of the water guiding groove 220 is connected to the flow dividing structure 216. When washing dry all-in-one operation, condenser tube 22 supplies the cooling water in to well cavity 213, behind the cooling water entering guiding gutter 220, flow downwards along guiding gutter 220, when the cooling water flows to on the reposition of redundant personnel structure 216, receive gaseous striking (can directly strike on reposition of redundant personnel structure 216 from the gas that air inlet 212 got into), under the effect of striking force, rivers are broken up into the water film, the heat transfer area grow, can carry out more abundant heat exchange with gas, thereby can improve the cooling effect, and, rivers can also move along with first air current 5 and second air current 6 after being broken up, further increase heat transfer area, can further improve the cooling effect.

It should be noted that, in this cooling manner, the flow dividing structure 216 shown in fig. 4 is preferably used, and the surface area of the flow dividing structure 216 is large, so that the water flow can be more favorably dispersed.

With continued reference to fig. 7, the shunting structures 216 are inclined from top to bottom in a direction away from the back sidewall 219. With such an arrangement, the adhesion of the cooling water to the surface of the flow dividing structure 216 can be reduced, so that the water flow is more easily broken up.

With continued reference to fig. 7, the chute 220 is inclined from top to bottom in a direction close to the rear sidewall 219. With such an arrangement, the cooling water can be prevented from separating from the water guide duct 220, and the cooling water can smoothly flow along the water guide duct 220.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
