Description

Large Roof Fan Apparatus for Factory Ventilation The present invention relates to a large roof fan device for factory ventilation, and more specifically, by changing the shape of the side portions of the first and second louver portions, the path of dust discharged through the roof fan device is changed to form a vortex, thereby solving the conventional problem in which dust collection is concentrated in a specific area of the roof surface where the roof fan device is installed, causing damage to the roof surface or contamination of the roof fan device surface. This is widely used. Roof fans primarily transport hot air, dust, and particulate matter generated within factories, contributing to maintaining a pleasant indoor environment. In particular, efficiently removing dust generated during work processes is a critical task for protecting workers' health and preventing damage to machinery and equipment. Conventional roof fan systems are structured such that a roof fan is installed on the ceiling to draw in factory air, which is then discharged to the outside through a flow path installed on the roof. While this system is effective for removing dust and debris from inside the factory, various problems frequently occurred as the discharged dust traveled along the flow path. In particular, conventional airflow channels are sloped vertically from top to bottom. Due to this structure, dust discharged through the channels frequently falls intensively onto the factory floor located below the roof fan. Consequently, dust spills onto specific areas of the floor, causing rapid wear or damage. This has frequently led to increased maintenance costs and reduced operational efficiency in the factory. In addition, conventional Euro designs do not allow dust to be discharged smoothly, causing it to accumulate inside the Euro or pool in specific areas. This can lead to performance degradation of the roof fan and hinder efficient air circulation when used for extended periods.

FIG. 3 is an enlarged view of the vicinity of the louver portion of a loop fan device according to the first embodiment of the present invention. FIG. 4 is an enlarged view of the vicinity of the louver portion of a loop fan device according to a second embodiment of the present invention. FIG. 5 is an enlarged view of the vicinity of the louver portion of a loop fan device according to the third embodiment of the present invention. Figure 6 is flow analysis data of dust discharged according to a conventional loop fan device. Figure 7 is an enlarged view of Figure 6.

Figure 9 is a fluid analysis of the dust flow of a loop fan device according to the second embodiment of the present invention. The present invention will be described in detail below with reference to the drawings. The embodiments described below are provided as examples to ensure that the concept of the present invention is sufficiently conveyed to a person skilled in the art. Accordingly, the present invention is not limited to the embodiments described below and may be embodied in other forms. Furthermore, in the drawings, the size and thickness of the device, etc., may be exaggerated for convenience. Throughout the specification, the same reference numerals indicate the same components. Figure 1 illustrates the configuration of a conventional general loop fan device. Below, the configuration of a conventional loop fan device will be explained with reference to Figure 1. The roof fan device includes a column (1) located on the roof of a factory, a fan (5) inside the column, a lower louver (2) located on the upper part of the column (1), an upper louver (3) spaced apart from the lower louver (2) at a predetermined distance in the vertical direction, and a connecting frame (6) connecting the column (1) and the roof floor surface. Dust collected along the space (4) between the lower louver (2) and the upper louver (3) is discharged to the outside. FIG. 2 illustrates a summary of the insulation near the lower louver (2) and the upper louver (3). Dust rises and falls inside the factory through the fan (5), and the collected dust is discharged to the outside through the space (4) between the lower louver (2) and the upper louver (3). At this time, since both the lower louver (2) and the upper louver (3) are tilted in the same direction, the discharged dust is concentrated at one point on the roof surface, and the surface becomes contaminated. FIG. 6 is a flow analysis of dust discharged according to a conventional loop fan device, and it can be seen that dust accumulates near the circle of the dotted line added for explanation as in FIG. 6. In addition, FIG. 7 is an enlarged view of FIG. 6, and it can
