A hanging structure for a wall fan, able to hang a wall fan on a wall, includes a board and a casing. The board to be locked on a wall is provided thereon with at least one first hanging member and at least one first locking member. The casing is provided therein with at least one second hanging member by which the casing can be hung on the first hanging member of the board. The casing is further provided with at least one second locking member to be locked together with the first locking member of the board to have the casing firmly fixed on the board and roughly covering the board. The hanging structure for a wall fan of this invention can simplify aligning, positioning and locking operation and can be firmly hung on a wall to avoid displacement for attaining effect of protection of the wall fan.

Generators are often provided in a frame to increase ease by which they can be transported, for example by lifting the frame with a crane. Generators comprise many, often moving, parts, and therefor maintenance and inspections are required. In order to access the generator, a frame is provided comprising four posts that connect a rectangular base part to a top structure, between which the generator is provided. The posts are provided near corners of the base part, and thus broad access windows are provided for accessing all sides of the generator. The generator’s fan may easily be swivelled out of the frame by its mounting on a swing arm again allowing more easy access to the generator. Doors may be provided to temporarily close of access to the generator, and gaps may be provided between doors and top structure to allow air intake for the generator.

The present invention relates to a wall ring for receiving in particular an axial fan, comprising an annular body with a flow inlet opening and a flow outlet opening and a central longitudinal axis X-X as well as an annular wall extending between both openings. The annular wall has a cavity which is enclosed by an outer wall and an inner wall, in which an electrical heating element may be secured at least over a partial area of the periphery of the annular wall. The annular body consists of at least two partial bodies which are formed by a division of the annular body in a separating plane that extends perpendicular to its longitudinal axis and are detachably connected to one another.

Wall ring for an axial fan

A fan, in particular an axial fan, comprising a support element with a wall ring and an electric fan motor which is mounted in the wall ring and comprises a fan rotor. The wall ring has on its outer periphery a hinge consisting of a first hinge part that is connected to the wall ring and a second hinge part that can be pivoted about a hinge axis relative to the first hinge part, wherein the second hinge part is designed as a terminal box for receiving electrical connectors. The invention further relates to a support element for such a fan.
