The specific embodiment of the utility model will be described in further detail below in conjunction with the schematic diagram.

Example 1.

As shown in Figures 1 to 5, a new type of air guide device FFU includes a box body 1, a fan 2, a filter 3 and an air guide device are arranged inside the box body 1, and the air guide device includes a symmetrical design. The first set of deflectors and the second set of deflectors on both sides of the fan, the lowest end of the first set of deflectors is lower than the lowest end of the second set of deflectors, the first set of deflectors The highest end of the second group of deflectors is lower than the highest end of the second group of deflectors. The first group of deflectors is located near the fan and consists of two mutually symmetrical first deflectors 4. The second group of deflectors The baffle is located at a position away from the fan, and consists of two mutually symmetrical second baffles 5, the cross section of the first baffle is in an inverted J shape, and the cross section of the second baffle is similar to "I" shape. The air guide device uses two sets of deflectors to solve the problem of uneven air outlet from the FFU. At the same time, the volume of the box can also be reduced, reducing the cost of the enterprise.

Continue as shown in Figures 1 to 5, any one of the first deflectors 4 has a notch a, and the notches are oppositely arranged symmetrically, and the opposite two edges of any one of the second deflectors 5 It has a first holding portion 51 and a second holding portion 52 extending to two adjacent inner walls of the box body. The notch of the first deflector makes the FFU air out more evenly, and at the same time, the second deflector guides the wind direction of the air inlet, which jointly acts on the FFU air outlet to make the air out evenly.

Continue as shown in Figure 1, the two ends of any one of the first deflectors 4 are fixed on two opposite inner walls of the box body 1 by rivets, the first of any one of the second deflectors 5 The holding portion 51 and the second holding portion 52 are fixed on two adjacent inner walls of the box body 1 by rivets. The rivets are fixed to increase the strength of the cabinet, so that the vibration and noise of the cabinet are small.

Continue as shown in Fig. 2 and Fig. 4, any one of the first deflector 4 and the second deflector 5 has a plurality of diffuser holes b, and the aperture of the diffuser hole is 0.4mm, which is effective reduced noise.

As shown in FIG. 5 , the angle between the first holding portion 51 and the second deflector 5 is 150°, and the angle between the second holding portion 51 and the second deflector is 120°. The setting of the second deflector plate is to guide the wind direction of the air inlet and realize uniform air outlet from the air outlet.

The above-mentioned new type of air guide device FFU solves the problem of uneven air discharge from the existing cabinet. At the same time, the volume of the cabinet can be smaller, and the air discharge can be uniform. At the same time, the cabinet has better strength and less vibration. Smaller, at the same time, the noise is greatly reduced, reducing the loss.

The above is only the preferred embodiment of the utility model, it should be pointed out that, for those of ordinary skill in the art, without departing from the inventive concept of the utility model, some deformations and improvements can also be made. Belong to the protection scope of the utility model.
