Description

Technical Field

[0001] The utility model belongs to the technical field of evaporative cooler induced draft fan inlet structures, and particularly relates to a hyperbolic fan cover plate structure for an evaporative cooler. Background Art

[0002] Existing evaporative coolers draw air through a tower-mounted fan. This air then flows upward through the water tank louvers, sequentially entering the heat exchange piping, spray area, water collection device, heat exchange piping, fan cover (plenum), and fan area, removing heat and cooling the medium. Existing fan covers are mostly square shells with built-in long, reinforcing ribs to meet strength requirements. However, these ribs impede air flow, particularly in corners where they create dead zones or vortices, increasing motor energy consumption. In winter, when condensation accumulates near the fan, the ribs act as deflectors, allowing water to drip onto the heat exchange tubes, leading to corrosion and leakage in the dry section. Furthermore, existing fan covers have a flat-plate structure, but these lack strength and are only suitable for small heat exchange equipment or applications where vibration resistance is less critical. They also lack a tapered plenum, resulting in a convex-concave flow pattern, which also increases wind resistance and motor energy consumption. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Embodiment 1:

[0022] like Figure 1-3As shown, a hyperbolic fan cover structure for an evaporative cooler comprises:

[0023] The hyperbolic plate 1 is an annular structure, and its cross-section is an arc-shaped structure that is concave toward its center. Since both ends of the hyperbolic plate 1 are arcs in the cross-section, it is called a hyperbolic plate. The vertical distance between the inner wall of the arc structure and its center line gradually increases from one end to the other.

[0024] The fan connecting ring 2 is an annular structure and is installed at the small diameter end of the hyperbola plate 1. The fan connecting ring 2 is mainly used to connect to the fan 7, specifically to the outer shell of the fan 7. When the fan 7 is working, Figure 3 As shown, the air can pass through the hyperbolic plate 1 from bottom to top and continue to flow upward;

[0025] The bottom plate assembly is installed at the large-diameter end of the hyperbolic plate 1, wherein the bottom plate assembly is mainly used to connect the heat exchange module of the evaporative cooler below, and is specifically installed at the upper end of the box body 8 of the heat exchange module. The hyperbolic plate 1 serves as a connector connecting the fan 7 and the heat exchange module, and has the effect of inducing wind.

[0026] A plurality of reinforcing ribs 3 are installed on the outer wall of the hyperbolic plate 1. This arrangement is intended, on the one hand, to improve the structural strength of the entire hyperbolic plate 1 and prevent the hyperbolic plate 1 from vibrating or shaking when the wind is too strong, thereby reducing noise and the chance of equipment damage. On the other hand, the reinforcing ribs 3 are arranged on the outside of the hyperbolic plate 1 to replace the traditional structure in which the reinforcing ribs 3 are arranged inside the fan cover, which can avoid the problem of condensed water dripping along the reinforcing ribs 3 onto the heat exchange tubes below, thereby avoiding corrosion and damage to the heat exchange tubes.

[0027] In this embodiment, the bottom plate assembly is a first flat plate 4 of a rectangular structure, which is welded to the large-diameter end of the hyperbola plate 1. A through hole is provided in the center of the first flat plate 4, which is connected to the internal space of the hyperbola plate 1. When in use, the first flat plate 4 can be directly installed on the box body 8 of the heat exchange module. More specifically, the reinforcing ribs 3 can simultaneously weld the first flat plate 4, the hyperbola plate 1 and the fan connecting ring 2 to increase the structural strength of the entire fan cover and extend its service life. The first flat plate 4 is used as the bottom plate assembly, which has the advantages of simple structure and convenient installation.

[0028] The fan connecting ring 2 is welded to the small-diameter end of the hyperbolic plate 1, and the outer wall extends toward the outside of the hyperbolic plate 1, mainly to facilitate the installation of the fan connecting ring 2 at the lower end of the fan housing 7, thereby improving the convenience during the safety process.

[0029] Example 2:

[0030] like Figure 4-5 As shown, the difference between this embodiment and the above embodiment is that the base plate assembly includes a second flat plate 5 in a square ring shape, and a cover plate 6 connected to the second flat plate 5, one end of the cover plate 6 has a square structure and is connected to the inner wall position of the second flat plate 5, and the other end has a circular structure and is connected to the large diameter end of the hyperbola plate 1.

[0031] That is, the combined structure of the cover plate 6 and the second flat plate 5 is used to replace the first flat plate 4 structure of the first embodiment. Its advantage is that this can solve the problem of wind resistance at the four corners of the first flat plate 4 in the first embodiment, so that when the air moves from bottom to top, there is no obstruction in its flow space, which has the advantages of better air circulation effect and lower wind resistance.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
