At the same time, the residual water is reduced, allowing the condensed water to flow into the condenser 400 along the flow channel, thereby improving the utilization efficiency of the condensed water.

According to some embodiments of the present application, with reference to Figures 5 and 6, the first included angle is α1, and in some embodiments, 0 degrees ≤ α1 ≤ 5 degrees. When the first angle α1 formed between the guide plate 20 and the horizontal plane is less than 5 degrees, the flow rate of the condensate water is relatively slow, which is not conducive to taking away the heat in a timely manner. When the angle is greater than 5 degrees, the water flow velocity is too fast and the water vapor contact time is short, resulting in a reduced water vapor heat exchange time and insufficient heat exchange, which affects the temperature of the exhaust gas. Therefore, by setting the first included angle α1 within this range, the flow rate of the condensed water on the guide plate 20 can be neither too fast nor too slow, and can always be maintained within an appropriate range to ensure the heat exchange effect. It should be noted that the first included angle α1 can be any angle between [0, 5]. For example, α1 can be 0 degrees, 2.5 degrees, or 5 degrees.

According to some embodiments of the present application, at least two baffles 20 are provided. The at least two baffles 20 are spaced apart in the vertical direction and arranged staggered with each other. The exhaust direction of the exhaust port 103 is consistent with that of the baffle 20 . The extension direction is the same. In some embodiments, at least two baffles 20 are spaced apart in the vertical direction and arranged staggered in sequence. For example, any two adjacent baffles 20 are staggered in the horizontal direction, one is connected to the left side wall of the dehumidification chamber 101, the other is connected to the right side wall of the dehumidification chamber 101, and so on, the condensed water It flows in the direction of the arrow on the guide plate 20 (refer to Figure 5), thereby forming an "S" shaped condensate water channel, which can extend the condensate water stroke, greatly increase the water vapor heat exchange area, and improve the heat exchange efficiency of condensate water and gas. . Referring to Figure 6, the gas moves in the direction of the arrow to exchange heat with the condensed water, and is finally discharged from the exhaust port 103, thereby increasing the heat exchange efficiency between the gas and the condensed water and improving the dehumidification and cooling capabilities of the dehumidification device 100.

In summary, the dehumidification device 100 of the present application can increase the condensed water stroke and water vapor heat exchange time by disposing at least one guide plate 20 between the spray plate 1072 and the condensed water outlet 105, and by connecting the condensed water inlet 104 and the inlet. The air port 102 is located above the deflector 20, and the condensed water inlet 104 is located below the deflector 20. At the same time, the exhaust port 103 and the air inlet 102 are located at the same end of the shell 10 and are in the shell with the condensed water inlet 104. on the diagonal line of the body 10 to better increase the contact time of water vapor in the dehumidification chamber 101. Secondly, by setting the deflector 20 to have a certain inclination, it is convenient for the condensed water to flow out in time and take away the heat, thereby improving the dehumidification capacity, thereby increasing The large heat exchange performance of the dehumidification device 100 improves the cooling and dehumidification capabilities of the dehumidification device 100 .
