Abstract
Description
Technical Field
[0001] The utility model relates to the field of heating, ventilation and air conditioning, and particularly relates to a novel inclined wet film cooling device. Background Art
[0002] At present, there are many applications for wet film cooling in the market. Generally, they are installed on the air inlet surface of the unit and are usually installed vertically. Since the common water distribution method for wet films is gravity-type water spraying, the wet films are conventionally installed vertically to achieve uniform water spraying. The method of gravity-type water spraying is as follows: a water distributor is installed at the top of the wet film. The water distributor is composed of a water inlet interface, a water distribution pipe, and a water distribution sheet metal. The water distribution pipe is commonly made of PVC or PPR pipe, and holes are drilled on the pipe and linearly arranged evenly. The water flowing out of the water distribution holes flows onto the water distribution sheet metal directly below, and holes or slots are opened on the water distribution sheet metal for re-water distribution. The water flows through the holes or slots of the water distribution sheet metal and then onto the lower wet curtain;
[0003] Reference Figure 1 , at the present stage, wet film products are increasingly used for cooling on dry cooler units. Among them, the core components of the dry cooler are two heat exchange coils arranged in a V shape, a fan is installed at the top, and the wet film is under negative pressure suction ventilation. Wet films also need to be installed obliquely for other units and special positions. The prior art has at least the following defects:
[0004] 1. The lower half of the wet curtain in the wet film is not thoroughly wet, only the upper half of the wet curtain is wet. Since the water cannot flow to the lower half due to a certain inclination angle, the wet curtain fails, reducing the evaporation efficiency of the wet film;
[0005] 2. Water drips and leaks on the windward side of the wet film, and the water leaks out of the equipment, resulting in water accumulation on the ground, which belongs to abnormal equipment leakage and is a quality problem;
[0006] 3. Water drifts and splashes on the leeward side of the wet film, and the water flies out of the leeward side of the wet curtain and drifts onto the internal equipment, which is likely to cause equipment damage, especially posing a great installation hazard to electronic components, and is also likely to cause water accumulation inside the equipment and the water leaks out of the equipment to the ground, which is a quality problem. Summary of the Utility Model
[0007] (I) Technical Problems to be Solved
[0008] In order to solve the above problems of the prior art, the utility model provides a novel inclined wet film cooling device.

[0030] In order to better explain the present utility model for easy understanding, the present utility model will be described in detail below with reference to the accompanying drawings through specific implementation manners.
[0031] Please refer to Figures 2 to 4 , the present utility model provides a new type of inclined wet film cooling device, including a water distributor 1 and a wet curtain assembly 2 arranged below the water distributor 1;
[0032] The wet curtain assembly 2 is inclined and forms an angle of 60 - 90° with the ground, and the wet curtain assembly 2 includes a first wet curtain 21 and a second wet curtain 22;
[0033] The wet curtain assembly 2 further includes an outer frame body 23, the first wet curtain 21 and the second wet curtain 22 are connected and installed in the outer frame body 23;
[0034] The first wet curtain 21 includes a first wet curtain paper 211 and a second wet curtain paper 212. A plurality of the first wet curtain papers 211 and the second wet curtain papers 212 are provided and cross each other to form a wet curtain net. The first wet curtain paper 211 forms an angle of 135° with the plane where the bottom of the outer frame body 23 is located, the second wet curtain paper 212 forms an angle of 45° with the plane where the bottom of the outer frame body 23 is located, and the first wet curtain paper 211 and the second wet curtain paper 212 form an angle of 90° with each other;
[0035] The second wet curtain 22 includes a third wet curtain paper 221 and a fourth wet curtain paper 222. A plurality of the third wet curtain papers 221 and a plurality of the fourth wet curtain papers 222 are provided and cross each other to form a wet curtain net. The third wet curtain paper 221 forms an angle of 60° with the plane where the bottom of the outer frame 23 is located, the fourth wet curtain paper 222 forms an angle of 35° with the plane where the bottom of the outer frame 23 is located, and an angle of 25° is formed between the third wet curtain paper 221 and the fourth wet curtain paper 222;
[0036] Function of the first wet curtain:
[0037] After water flows into the first wet curtain 21, it usually follows two water paths. Water path one flows towards the air inlet surface with a horizontal angle of 75° downward. Due to the large angle, under the action of gravity, the water flow rate is fast and the penetration time is short, and a large amount of water flows into water path one. Water path two flows towards the air outlet surface with a horizontal angle of 15° downward, and the water can also flow smoothly backward. Since the raw material of the wet curtain is a fibrous material paper with strong water absorption, the water easily penetrates downward, and the lower part of the wet curtain can be wetted, and the whole wet curtain can be wetted;
[0038] However, when the external wind speed is too high, the water droplets on the windward surface can be carried back to the wet curtain by the wind and will not flow out, but will be carried out by the wind from the leeward surface, forming water drift, which causes quality problems.
[0039] Function of the second wet curtain:
[0040] After water flows into the second wet curtain 22, it usually follows two water paths. Water path one flows towards the leeward surface and a small amount of water penetrates towards the air inlet surface, with a horizontal angle of 5° upward. Water path two flows towards the leeward surface with a horizontal angle of 30° downward. Since the raw material of the wet curtain is a fibrous material paper with strong water absorption, the water easily penetrates downward. When there is no wind on the windward surface of the wet curtain, due to the strong water absorption of the wet curtain, the water can slowly penetrate and can be thoroughly wetted, and there is no water dripping on the windward surface of the wet curtain. However, in the case of wind, it cannot be thoroughly wetted. Since the amount of water on the windward surface is small and it relies on penetration to get wet, the water is easily evaporated, resulting in the phenomenon that the wet curtain becomes dry. When the wind blows inwards, it is also not conducive to the diffusion of water towards the windward surface, and the dry wet curtain will reduce the evaporation efficiency.
[0041] In this application, the first wet curtain 21 and the second wet curtain 22 are combined. A large amount of water accumulates at the end face of the windward surface of the first wet curtain 21. For the second wet curtain 22 closely attached thereto, since the angles are all tilted upwards horizontally, the water will not flow upwards and can only wet the wet curtain by penetration. Since the second wet curtain 22 is relatively thin and has good wetting performance, it can ensure that the whole wet curtain is thoroughly wetted, and the water will not drip from the windward surface. In the case of wind, since the amount of water at the end face of the windward surface of the first wet curtain is large and greater than the evaporation amount of water, the wet curtain can remain wet. The wet curtain in this application has good wetting performance, the whole wet curtain is thoroughly wetted, there is no water dripping on the windward surface of the wet curtain when there is no wind, and the windward surface can also remain wet under normal wind speed conditions. There is no water drift on the leeward surface of the wet curtain, ensuring high-efficiency and stable evaporation efficiency of the wet curtain.
[0042] In this embodiment, the second wet curtain is arranged on one side of the windward surface, and the first wet curtain is arranged on one side of the leeward surface.
[0043] In this embodiment, the thickness of the first wet curtain is 20 - 300 cm.
[0044] In this embodiment, the thickness of the second wet curtain is 20 - 50 cm.
[0045] In this embodiment, the first wet curtain paper 211, the second wet curtain paper 212, the third wet curtain paper 221, and the fourth wet curtain paper 222 are all made of fiber material paper with strong water absorption.
[0046] The working principle of the present utility model is as follows:
[0047] Combining the first wet curtain 21 and the second wet curtain 22, a large amount of water accumulates at the end face of the windward surface of the first wet curtain 21. Since the angles of the adjacent second wet curtain 22 are all tilted upwards horizontally, the water will not flow upwards and can only wet the wet curtain by osmosis. Since the thickness of the second wet curtain 22 is relatively thin and the water permeability is good, it can ensure that the overall wet curtain is wet, and the water will not drip from the windward surface. In the case of wind, since the amount of water at the end face of the windward surface of the first wet curtain 21 is large and greater than the evaporation amount, the wet curtain can remain wet. The wet curtain of the present application has good water permeability, the whole wet curtain is wet, there is no water dripping on the windward surface of the wet curtain under the condition of no wind, and the windward surface can also remain wet under the condition of normal wind speed. There is no water splashing on the leeward surface of the wet curtain, ensuring high-efficiency and stable evaporation efficiency of the wet curtain.
