Problems solved by technology

[0002] The fan filter unit is a self-powered air supply filter device, which is called (Fan Filter Unit) in English. It is a modular terminal air supply device with filtering effect. The FFU fan filter unit can be used for modular connection, and the FFU fan filter is used. The unit is widely used in clean rooms, clean operating tables, clean production lines, assembled clean rooms and local Class 100 applications, while the existing FFU box structure generally adopts the form of two air ducts and downwind guide plates, forming two The air outlet, so that the airflow in the box is not evenly distributed, resulting in a large difference in the wind speed of the various surfaces in the box, making the overall efficiency of the FFU not high, it is difficult to have room for improvement, and the structure is complex, there are many parts in the box, and the assembly is time-consuming and laborious , the efficiency is low, and the structure and support strength of the FFU box are not enough. When stepping on it, it is easy to cause the box to deform and reduce the service life. Therefore, it is necessary to design a FFU four-air channel box structure to solve the existing The problem

Embodiment 1

[0024] see Figure 1-Figure 5 As shown, the present invention provides a technical solution: a FFU four-air channel box structure, including an FFU box 1, a universal fixing plate 2 connected to the top side of the inner cavity of the FFU box 1, and the universal fixing plate 2 is set as a rectangular settling tank structure, and the controller 3 is installed in the universal fixed plate 2, which is convenient for installation, and the controller 3 is sunk inside the FFU box 1, which plays a good protective role and prevents the staff from touching Inverted, safe and reliable, the top center of the FFU box 1 is connected with an air inlet grille structure 4, which adopts a square opening design of 25*25cm, and the air inlet grille structure 4 includes a protective cover 5, and the protective cover 5 It is sealed and connected with the FFU box 1, and the top of the protective cover 5 is provided with an installation through groove 6, and the inside of the installation through g...

Embodiment 2

[0030] Such as figure 2 and image 3As shown, the air supply plate 16 is symmetrically connected to the bottom of the inner cavity of the FFU box 1, and the outlets of the air outlet 15 are correspondingly directed to the four corners of the FFU box 1, so that the airflow flowing out from the air outlet 1 can pass through the air supply plate 16 quickly. The guided air flow moves downward, which improves the air supply volume and air supply efficiency.

[0031] The present invention is improved in that: this kind of FFU box structure with four air ducts can form four air ducts by adopting the structural form of four downwind guide plates, reduce internal turbulence points, and make the air flow inside the box more smooth and uniform, and at the same time Simplify the box structure, facilitate assembly, and improve work efficiency. The controller 3 adopts a sunken shared cover design, which facilitates the replacement of different types of controllers in the later stage. Thro...

Abstract

The invention relates to an FFU four-air-duct box structure, which comprises a FFU box, one side of the top of the inner cavity of the FFU box body is connected with a universal fixing plate; the universal fixing plate is arranged to be of a rectangular settling tank structure. A controller is mounted in the universal fixing plate; the center of the top of the FFU box body is connected with an airinlet mesh enclosure structure which comprises a protective cover in sealed connection with the FFU box body; a mounting through groove is formed in the top of the protective cover; the inner side ofthe mounting through groove is connected with an air inlet mesh enclosure; an air inlet is formed under the air inlet mesh enclosure. The structure is simple, stable and reliable, convenient to install and use, capable of enhancing the structural strength of the box body, pressure-resistant and durable. Four air channels can be formed by adopting the structural form of the four downwind guide plates, internal turbulent flow points are reduced, airflow in the box body is smoother and more uniform. Meanwhile, the box body structure is simplified, assembling is convenient, the working efficiencyis improved, energy consumption is reduced, and cost is saved.
