Abstract
A motorized hand tool such as a cordless ratchet wrench that has a motor, and a housing that encloses or houses the motor. The motor includes one or more exhaust ports that expel exhaust air out of the motor. The housing includes one or more exhaust ports and inwardly projecting protrusions or deflectors that extend around the exhaust ports. The inwardly projecting protrusions/deflectors extend in a direction towards the motor exhaust ports, and/or are at least partially disposed in the motor exhaust ports to direct exhaust air out of the housing and prevent exhaust air from recirculating near the motor and electronic components of the tool.
