摘要：
A lawnmower and lawnmower cooling system can include a housing configured to contain a motor, a battery assembly, a motor driver, and a controller. The housing can include at least one air inlet located adjacent to the top surface of the deck. The housing can include a driver chamber, a battery chamber, a motor chamber, and at least one air outlet. A fan can be mounted in the housing such that, when the fan operates, air enters the air inlet, flows through the driver chamber away from the top surface of the deck along the upward direction, passes through the motor driver along the upward direction, passes into the battery chamber and flows through the battery pack, passes into the motor chamber and flows through the electric motor, and exits the motor chamber through the at least one air outlet.
