NOVELTY - The utility model claims a new semiconductor cooling and heating technique area, especially relates to a kind of one semiconductor heating plate. Including use for cold side of heat, for heat end of heat abstractor, equipped with the N type semiconductor and P-type semiconductor at the cold end and hot end between, connected with the N type semiconductor and metal conductor and the P type semiconductor, power supply, the metal conductor is set with power for connected with positive negative electrode of the power source, wherein the N type semiconductor is set with graphene, or the P type semiconductor is set with graphene, or said N type semiconductor and said P type semiconductor are provided with graphene. Even though the hot end and end is set with heat abstractor device the semiconductor heating plate too can protect it would not burn, which ensures the normal work.
