Wind Carrier / Cooling pad

We can't avoid using computers in a low temperature environment in generally, such as winter or air-conditioned room. Maybe the low temperature is fine to somebody, but it's easy to cause the disease to others.
As a result, I try to prevent the cold hands and feet from computer users working in the cold environment. I take the notebook's vents as a source of heat, combine with exhaust pipe. Make the heat blow hands through the pipe. Keeping the hands temperature, and do not cost additional electricity.
