ABSTRACT:
A climate control pad includes a pad body having a climate treating surface and an air circulating circuit formed thereon for preserving a volume of air within the air circulating circuit in a circulating manner, and a heat generating element, which is a fiber heating wire, disposed in the air circulating circuit for generating heat to increase the temperature of the air within the air circulating circuit so as to evenly distribute the heat from the heat generating element on the climate treating surface of the pad body. In addition, the pad body is adapted to incorporate with a cooling source to provide a cooling air towards the climate treating surface of the pad body.
