Abstract
A cooling enclosure is mounted to the frame of a grass mowing machine adjacent the engine cooling fan of an internal combustion engine. The engine cooling fan draws ambient air across the controllers and batteries in the cooling enclosure. The cooling enclosure includes a one piece molded plastic structure that holds and supports batteries and electronic controllers at positions spaced from its bottom surfaces. One or more removable or hinged panels cover the top of the structure.

A cooling enclosure mounted to the frame of a grass mowing machine having an internal combustion engine and an engine cooling fan, comprising:
- a one piece structure having an air outlet opening adjacent the engine cooling fan and a screened air inlet opening in a bottom surface thereof, the structure holding and supporting a plurality of batteries and electronic controllers;
- and
- a removable panel covering at least a portion of the one piece structure;
- a plurality of mounting supports molded into the cooling enclosure on which the controllers and the batteries are mounted spaced above the bottom surface to provide a flow path for ambient air between the batteries and the controllers under and around the controllers while the removable panel covers the structure.
A cooling enclosure mounted to the frame of a grass mowing machine adjacent an engine cooling fan of an internal combustion engine, comprising:
- a one piece molded plastic structure holding and supporting a plurality of batteries and electronic controllers in spaced relation and having an openable and closeable panel;
- and
- an air inlet and an air outlet in the one piece molded plastic structure and providing flow paths for ambient air through the cooling enclosure under and around the sides of the batteries and electronic controllers while the panel is closed;
- the air outlet positioned adjacent the engine cooling fan;
- and
- a screen on the air inlet underneath the batteries.
A cooling enclosure mounted to the frame of a grass mowing machine adjacent an engine cooling fan of an internal combustion engine, comprising:
- a molded plastic structure having a bottom surface and supports molded therein to support at least two batteries and at least two controllers in spaced relation to provide a flow path for ambient air under and between the batteries and the controllers;
- an air inlet through a screened bottom surface under the supports for ambient air to flow into the molded plastic structure under the batteries;
- and
- an air outlet above the controllers for ambient air drawn by the engine cooling fan to be drawn out from the molded plastic structure.
