Improve a diffusing dividing plate for freezer airflow homogeneity, comprise pod apertures, flow-disturbing projection, water conservancy diversion mainboard, trip bolt, deflector draw-in groove.Freezer diaphragm carries out freezer installation of ceiling by peripheral hardware support, trip bolt or steel bonding glue, deflector draw-in groove.
New-style refrigeration house diffusing baffle plate diversion hole is oval inclination drill way layout, and duct gradient is 45 °.Inclined ellipse drill way layout flows into the kinetic energy dissipation of pod apertures air-flow by reducing, flow-disturbing projection carries out rectification to flowing through pod apertures surrounding fluid, improves and enters pod apertures charge flow rate.
New-style refrigeration house diffusing baffle dimensions is the wide square corrosion resistant plate of 2m length × 2m, and diffusing block board thickness is 5mm, and the single number of pores of dividing plate is respectively 10 and 11, arranged crosswise.
New-style refrigeration house diffusing dividing plate flow-disturbing shape for lugs is half ring-like curved surface, is arranged on each pod apertures same side, and flow-disturbing projection concave surface is just to blowing main flow, and convex surface is back to blowing main flow.
New-style refrigeration house diffusing dividing plate carries out Modular assembled according to freezer area size, installs according to refrigeration area adjustment dividing plate quantity.
New-style refrigeration house diffusing dividing plate carries out adjustment according to wind turbine layout form and installs; Freezer air-cooler is cross air blasting mode, and diffuser plate flow-disturbing projection concave surface is just to blower fan air-out main flow, and other regions, the air-out main flow left and right sides, diffuser plate flow-disturbing projection concave surface is back to fan outlet.
New-style refrigeration house diffusing dividing plate is used for lower blowing-type freezer, on the downside of lower air-supply freezer blower fan and around 16m
2in scope; Diffuser plate flow-disturbing projection concave surface is back to air-cooler, and other region concave surfaces are just to air-cooler.
The present invention have energy-conservation, structure is simple, the feature such as easy for installation, is particularly suitable for the freezer of stable food.The present invention significantly can improve the uniformity of cool house internal air flow method.Fan jet flow is rationally evenly distributed to freezer everywhere, realizes goods lowering temperature uniform in freezer.Installed by artificial set direction, can district grid cold.
