Description

[Detailed description of the invention] This invention completely removes water droplets and frost that adhere to the heat exchange coil, and also prevents air turbulence around the heat exchange coil, resulting in a good refrigeration/cooling machine with excellent heat exchange efficiency. The purpose is to provide a wind blowing and defrosting device.

Usually, this kind of frost removal device for a heat exchange coil has cross-sectional water guide plates 2, 2 attached to the inner surface of a water sprinkling plate 1 at appropriate intervals in the length direction of the coil, as shown in the first figure. A water guide pipe 5 formed by opening a large number of water injection holes 6, 6, 6 on the periphery inside the water guide plates 2, 2.
The water flowing through the pipe is supplied to the water injection hole 6,
The frosting and thawing of the heat exchange coil A was performed by the water droplets that were sprayed onto the inner surfaces of the shaped water guide plates 2, 2 and dripped on the inner surfaces.

However, in the above structure, since both sides of the water guiding plates 2, 2 are formed of vertical flat plates, the water droplets sprayed on the inner surfaces of the water guiding plates 2, 2 flow directly downward, and this These water droplets do not drip onto each heat exchange pipe reliably, and therefore not only is it difficult to completely freeze and thaw, but also there is a slight gap between the water guide plate 2 and the upper side of the heat exchange coil A. However, it has been extremely difficult to expect a good effect because air flows turbulently in the gap and dripping water scatters around the gap.

The main purpose of the present invention is to fundamentally solve the above-mentioned drawbacks, and the present invention is based on the inner surface of a water sprinkling plate 1 which is arranged above a heat exchange coil A at a fixed interval. In addition, horizontally long water guide plates 2 having a cross-sectional shape formed by extending one side piece long downward to form a wind section 3 are arranged at regular intervals, and a wind section below the water guide plate 2 is provided. 3. On the front side, the wind blowing and water collecting plates 4 which can be bent into a dog-shaped shape are arranged in parallel in order to open the slit grooves a below the tips, and furthermore, inside each of the shaped water guiding plates 2, a large number of Water injection hole 6,6
It is characterized by having a water guide pipe 5 formed by opening a hole therein.

In addition, the dripping water from the water reservoir part b flows onto the lower heat exchange pipe P through the tip slit groove a portion of the water reservoir part b formed by the wind blower part 3 and the wind cutter/water reservoir plate 4. By locating the pipe so that the water drips reliably onto the heat exchange pipe P, the dripping water can be reliably dripped onto the heat exchange pipe P, thereby making it possible to more effectively frost and thaw the inside of the coil.

As described above, in the present invention, the shaped water guiding plates 2 each having one piece extending downward to form the winding section 3 are arranged side by side at regular intervals on the inner surface of the water sprinkling plate 1, and 3, dog-shaped wind and water storage plates 4 are arranged in parallel, and slit grooves a are opened at the bottom of the tips, so that water can be guided to the water guide pipe 5. As a result, the water in the pipes is sprayed out from the respective water injection holes 6 to the surrounding area, flows down the sides of each water guide plate 2, and flows into the wind section 3 and the wind flow/water storage board 4.
Water is stored in the water storage part b formed by the slit groove a, and this water becomes suitable water droplets below the slit slot a to remove ice and frost from the heat exchange coil A.

In particular, in the present invention, the slit slot a portion is positioned in the vicinity of the heat exchange coil A directly above each heat exchange pipe P, that is, by positioning the dripping water onto the heat exchange pipe P to ensure that the dripping water drips onto the heat exchange pipe P. As a result, the dripping water can be reliably dripped into the heat exchange pipe P without being scattered around, and a better effect can be expected.

Moreover, by arranging the tip of the wind section 3 as close as possible to the upper side of the heat exchange coil 1, the horizontal flow of air on the upper side of the heat exchange coil A is completely blocked, thereby preventing the dripping water from flowing around the surrounding area. This has the effect of completely preventing the air from being blown into the air and improving air circulation.
