Design and function of the Hand Warmer
Purpose
The Hand Warmer main functionality is to keep the area around a
wheelchair input device warm. This increases the comfort of the
user and its ability to control the input device.
General
The device is an air heater, which is powered by the wheelchair
battery power (24V) and contains its own control electronics.
Air is drawn at the front, heated, and forced out again at the front
using an internal fan. As the air inlet and outlet are at the same
side, warm air is recycled instead of using air from the cold
environment. This results in a huge advantage with regards to
power consumption and efficiency.
