ABSTRACT:
A sporting implement and more specifically, a racket. The racket has a frame connected to a handle and a tubular member disposed about the frame and handle. A liquid refrigerant located in the tubular member serves to dissipate heat generated by the user's hand. The tubular member has portions which define an evaporator and a condenser such that heat from the user's hand evaporates the refrigerant and the evaporated refrigerant travels to the condensing area where it changes back to a liquid state.
