Embodiment Construction

[0028] The grille or just the grille for the ventilator according to the patent of the present invention is a single-piece grille arranged downstream of the blowing element (V) of the ventilator (AP) basically comprising a mesh portion (G ) and the stator part (E).

[0029] The grid section (G) is formed by radial and concentric fins (A) forming concentric rings or radial ribs and arranged upstream of the stator section (E), i.e. here by the fan ( V) next to the blowing element (V). The grid part (G), in addition to being configured as a safety element against access to the rotating and / or internal parts of the device (AP), also forms the beginning of the stator (E), the fins (A) of the grid part being the stator ( E) The initial part of the air conduction of the blade (P), where the fins (A) have an airfoil profile, the purpose of which is to increase the recovery efficiency of the dynamic air pressure from the fan (V), converting the dynamic air pressure into The static pr...

Abstract

The present patent application relates to a grille for a ventilation apparatus arranged downstream of blowing elements (V) of ventilation apparatuses (AP), comprising a grille portion (G) arranged upstream of a stator portion (E).

Description

technical field [0001] The invention patent belongs to the field of equipment and devices for air cooling and ventilation, more specifically, to the field of air-conditioning equipment and fans. [0002] Introduction [0003] The present invention relates to an air blowing grille with a built-in stator applied in a device with a ventilation element, wherein said grille performs the protective and supporting functions inherent in grilles of this nature, as well as restoring the air passing through the grille A function of part of the dynamic pressure of the air from the air blower of the device for which the grille is intended. [0004] For the same angular velocity of the equipped air blowers, the grid according to the invention can significantly increase the air flow of the corresponding equipment, which increases by almost 30% compared with similar equipment known from the prior art. Background technique [0005] Various configurations of grids or grates for ventilators ...
