Abstract
The utility model belongs to the technical field of air purification, a novel low energy consumption high efficiency FFU is related to, including the box with be fixed in the fan at box middle part, around being provided with six air guide plates in the box of fan rotational symmetry, the cross-section of air guide plate is for using the fan axis as the Archimedes helix of original point, and its projection in the box bottom surface is obeyed R ═ 10 (1+ t) along the air guide plate, x ═ R cos (t 360 °), y ═ R sin (t 360 °), and 1.5R is not less than R and is not more than 2.14R, and R is the fan radius. This FFU is through changing the mode of setting up of guiding plate with the wind, and the total pressure improves more than 330Mpa, lets pneumatic efficiency improve more than 77% simultaneously, has reduced the energy consumption.
Description
Technical Field
The utility model relates to an air purification technical field, in particular to novel low energy consumption high efficiency FFU.
Background
FFU is called Fan Filter Units, and Chinese means Fan Filter unit. In order to improve the energy efficiency, a fan filter unit with high energy efficiency (patent number: ZL201810913277.1) is developed by the company, and is characterized in that four downwind guide plates are adopted, so that the energy efficiency is improved to more than 60%, but the market competitiveness can be obtained only by further improving the energy efficiency.
Therefore, it is necessary to develop a new device structure to solve the above problems.
SUMMERY OF THE UTILITY MODEL
A primary object of the present invention is to provide a novel low energy consumption and high efficiency FFU, which can improve pneumatic efficiency to more than 77%.
The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a novel low energy consumption high efficiency FFU, includes the box and is fixed in the fan in box middle part, around fan rotational symmetry be provided with six air guide boards in the box, the cross-section of air guide board is for the Archimedes spiral line of using the fan axis as the original point, and the projection of one of them air guide board in the box bottom surface obeys R10 (1+ t), and x R cos (t 360 °), y sin (t 360 °), and 1.5R is not more than R and is not more than 2.14R, and R is the fan radius.
Specifically, an outward flange is arranged at one end, close to the fan, of the downwind guide plate.
Specifically, two sides of the downwind guide plate are respectively fixed on an integral fixing plate.
The utility model discloses technical scheme's beneficial effect is:
this FFU is through changing the mode of setting up of guiding plate with the wind, and the total pressure improves more than 330Mpa, lets pneumatic efficiency improve more than 77% simultaneously, has reduced the energy consumption.
Drawings
FIG. 1 is a schematic structural diagram of a novel FFU with low energy consumption and high efficiency according to an embodiment.
The figures in the drawings represent:
1-a box body; 2-a fan; 3-guiding plate following wind, 31-flanging; 4-fixing the plate.
Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1, the utility model discloses a novel low energy consumption high efficiency FFU, including box 1 with be fixed in the fan 2 at box 1 middle part, around being provided with six air guide plates 3 along wind of 2 rotational symmetry of fan in the box 1, the cross-section of air guide plate 3 is the Archimedes helix that uses fan 2 axis as the initial point, and the projection of its one of it air guide plate 3 in the box 1 bottom surface obeys R10 (1+ t), x R cos (t 360 °), y sin (t 360 °), and 1.5R is not less than R and is not more than 2.14R, R is the fan radius. According to test display, the adoption of the arrangement mode of the downwind guide plate 3 improves the pneumatic efficiency to more than 77 percent and reduces the energy consumption.
As shown in fig. 1, the downwind guide plate 3 is provided with a flange 31 at an end close to the fan 2. The inner side of the outward flanging 31 reduces the loss of wind power along the flowing track of air passing between the two downwind guide plates 3, and meanwhile, the tail part of the downwind guide plate 4 is convenient to erect, so that the stability of the downwind guide plate in fixation is improved, and the downwind guide plate 4 is prevented from deforming under the action of continuous wind power.
As shown in fig. 1, the two sides of the downwind guide plate 3 are respectively fixed to an integral fixing plate 4. During installation, the downwind guide plate 3 can be fixed on the fixing plate 4 firstly to form a frame structure with stable structure and then is fixed in the box body 1, so that the installation is fast and convenient.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
