Heat sink for gas-fueled appliance

Abstract

A gas-fueled appliance includes a shell, a can, a transmitter and a heat sink. The can is put in the shell. The burner is also put in the shell. The transmitter includes a valve connected with the can, a regulator connected with the valve and a pipe leading to the burner from the valve. The heat sink is used for absorbing heat from air in the shell and passing the heat to the transmitter.
