NOVELTY - This utility model relates to a CPU heat radiator, especially relates to a kind of CPU heat abstractor device. Comprising heat guide piece and semiconductor refrigeration piece, the guide piece is set with between hot surface on the cold end face of the semiconductor cooling chip and CPU chip, heat guide surface connected with the cold end face and the CPU core chip of the semiconductor cooling chip, wherein the N type semiconductor and the semiconductor cooling chip is set with graphene, or the semiconductor cooling chip and P type semiconductor is set with graphene, or the semiconductor cooling chip and N type semiconductor and P-type semiconductor are formed graphene. Increase temperature difference of the semi-conductor refrigeration sheet cold end heat. Even though the hot end surface end is set with heat abstractor and the semi-conductor refrigerating device too can protect it would not burn, which ensures the normal work.
