[0020] Hereinafter, the horizontal condensing and flow equalizing filter unit in the laboratory of the present utility model will be specifically described with reference to the drawings.

[0021] As Figures 1 - 5 shown, the horizontal condensing and flow equalizing filter unit in the laboratory includes an air inlet section 1, a plate filter section 2, a chilled water coil section 3, a centrifugal fan section 4 with a volute, and a flow equalizing air outlet section 5; the input end of the air inlet section 1 is connected to the air inlet 11 by bolts, the output end of the air inlet section 1 is connected to the input end of the plate filter section 2 by bolts, the output end of the plate filter section 2 is connected to the input end of the chilled water coil section 3 by bolts, the output end of the chilled water coil section 3 is connected to the input end of the centrifugal fan section 4 with a volute by bolts, the output end of the centrifugal fan section 4 with a volute is connected to the input end of the flow equalizing air outlet section 5 by bolts, and the output end of the flow equalizing air outlet section 5 is connected to the air outlet 54 by bolts; inside the flow equalizing air outlet section 5, there are a guide vane 511, a flow equalizing plate 512, a variable aperture plate 521, and a streamlined guide vane 522.

[0022] Preferably, the flow equalizing air outlet section 5 adopts an integrated housing design. The flow equalizing air outlet section 5 includes a flow equalizing section 51, a transition section 52, and an air outlet section 53, which are enclosed in the same housing. The flow equalizing section 51, the transition section 52, and the air outlet section 53 are respectively connected by bolts; the flow equalizing section 51 and the air outlet section 53 are integrally designed, reducing the turbulence and eddy current phenomena during the fluid conversion process and improving the stability and uniformity of the air flow.

[0023] Preferably, inside the flow equalizing section 51, there are a guide vane 511 and a number of flow equalizing plates 512. Along the air inlet direction in the flow equalizing section 51, there are successively the guide vane 5D and the flow equalizing plates 512. The guide vane 511 is connected to the flow equalizing section 51 by bolts, and a gasket is installed at the gap.

[0024] Preferably, the flow equalizing plates 512 are connected to the flow equalizing section 51 by bolts, and gaskets are installed at the gaps. The surfaces of the flow equalizing plates 512 are provided with a number of holes. The number of flow equalizing plates 512 is arranged along the air inlet direction, and the holes on the surfaces of the flow equalizing plates 512 gradually decrease; the composite flow equalizing structure can more effectively reduce the turbulence and eddy current phenomena during the fluid flow process and improve the flow equalizing effect and stability.

[0025] Preferably, a variable-aperture plate 521 and a streamlined guide vane 522 are provided inside the transition section 52.

[0027] In this embodiment, air enters from the air inlet 11, and successively passes through the air inlet section 1, the plate-type filter section 2, the chilled water coil section 3, and the centrifugal fan section 4. When entering the uniform-outlet air section 5, it first passes through the guide vane 511 to guide the air flow to flow along a predetermined path, avoiding the uneven distribution caused by the air flow directly impacting the next-stage uniform flow plate 512. Through the gradual refinement of the air flow distribution by the multi-stage uniform flow plates 512, when the gas passes through the transition section 52, the variable-aperture plate 521 gradually diffuses the air flow and smoothly enters the air outlet. The streamlined guide vane 522 guides the air flow to flow along a predetermined path, avoiding the generation of dead corners and eddy current regions, and finally the air flow is discharged through the air outlet 54.

For those skilled in the art, the present application may have other optimization schemes and additional functions. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
