  • Patent number: 11215380
    Abstract: A combustion air blower includes a blower housing, an impeller fan within the blower housing, and an embossment to restrict airflow from the combustion air blower. The blower housing has a discharge conduit defining a discharge passageway. The discharge conduit is adapted and configured to receive a baffle such that, when the baffle is received, the baffle extends inwardly into the discharge passageway from a first wall towards a second wall opposite the first wall. The baffle restricts airflow within the discharge passageway. The embossment is in the discharge passageway and in the second wall and extends towards the first wall such that the embossment restricts airflow within the discharge passageway. The embossment cooperates with a baffle to provide a reduced cross sectional area of the discharge passageway in comparison to an upstream portion.

  • Patent number: 11197394
    Abstract: Apparatuses and methods are provided for blocking removal of an air-moving assembly from a housing when in operational state. The apparatus includes a protective louver assembly having a louver(s) and an interlock element(s). The louver(s) is disposed at an air inlet or an air outlet of the air-moving assembly, and pivots between an operational and a quiesced orientation, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The interlock element(s) is associated with the louver(s) to pivot with the louver(s) between the operational orientation and the quiesced orientation. In the operational orientation, the interlock element(s) blocks, at least in part, access to at least one fastener securing the air-moving assembly within the housing, and thereby prevents removal of the air-moving assembly from the chassis when in the operational state.

  • Patent number: 11029059
    Abstract: A passive cooling system routes air from an enclosure to an ambient environment, via a chimney effect, through one or more indirect pathways and re-directs environmental elements received from the ambient environment. One or more vanes are arranged within an interior space, such that the vanes collectively form one or more indirect pathways to the ambient environment. The vanes preclude environmental elements, including precipitation and particulate matter, from passing through the interior space and into the enclosure. Environmental elements are re-directed by one or more of the vanes, at least in part, to an exterior of the passive exhaust system. Dampers may be adjusted to control airflow through the passive cooling system and restrict environmental elements from entering the passive cooling system. Liquids received from the ambient environment may be re-directed into a reclamation system for use in a cooling system.
