Benefits of technology
The patent is about a cooling system for electric motors in a blower casing. The system includes an impeller casing with a tapered blower inlet, an impeller cover with a volute impeller cavity, and a fan baffle. The impeller casing redirects air from the impeller to a single vertical outlet. The fan baffle forces cooling air through the motor and not around the shell, allowing different motors to be used in the same blower casing. The cooling fan casing has a fan cover with a volute fan cavity and downward facing cooling air outlets. The entrance of rain water is minimized, and air filters and mist separators are used for the cooling air inlet and outlet. The technical effects of this system include reduced blower power, improved cooling efficiency, and extended motor life.
Problems solved by technology
As a result of vapor intrusion, the air within buildings may become contaminated thereby exposing individuals within the buildings to contamination.
Radon is a Class A carcinogen that, according to scientific studies, can cause harmful effects on human lung tissue.
The soil vapors exhausted by the blower may be flammable.
The contaminated air may have a high dew point since it is exhausted from the ground below the building.
This may cause condensation in the impeller casing or the outlet duct, especially in cold weather.
Thus, the cooling air is trapped within the enclosure.

A weather resistant blower casing has an impeller casing, an electric motor casing, a blower baffle, a cooling fan casing and a fan baffle. A downward facing cooling air inlet is provided in the electric motor casing to draw in filtered cooling air into the electric motor without drawing in rainwater. The cooling air outlet is in the cooling fan casing and is also downward facing. The fan baffle makes sure that the cooling air goes through the electric motor. The blower baffle is between the electric motor casing and impeller casing so that the air flowing through the impeller does not mix with the cooling air flowing through the motor. All elements are joined together with a weather tight seal.
Description
TECHNICAL FIELD[0001]The inventions described herein are in the field of outdoor blower casings.BACKGROUND ART[0002]Vapor intrusion is a process by which chemicals (e.g., volatile organic compounds (VOCs), radon, etc.) in soil and / or groundwater migrate to or seep into building spaces. These vapors can be released from contaminated soil and / or groundwater underneath buildings. The vapors may enter basements, crawl spaces, rooms and / or other areas of a building or structure. As a result of vapor intrusion, the air within buildings may become contaminated thereby exposing individuals within the buildings to contamination.[0003]Generally, VOCs are man-made chemical compounds that have a high vapor pressure and low water solubility. VOCs can be used and produced in the manufacture of fuels, paints, pharmaceuticals, and refrigerants. They are typically included in industrial solvents, paint thinners, dry cleaning fluids (e.g. tetrachloroethylene), fuel oxygenates (e.g. MTBE), and by-prod...
