Abstract: The invention is about a waste heat re-cycle cooling system, has a Peltier device, a waste heat recycling circuit, and a processor. The Peltier device has a cold side close to room and a hot side, the cold side is connected to a cooling pipe, and a fan arranged on one side of the cooling pipe is configured to blow air over the cooling pipe to cool down air and then blow the cooling air into room. The processor is configured to control the Peltier device and the waste heat recycling circuit. The invention can effectively utilize the waste heat generated by cooling and improve the cooling efficiency.

Abstract: A brush plate has an insulating substrate, at least one pair of brushes mounted on the insulating substrate, and a conductor for supplying power to the brushes. The conductor includes at least one overheat protection portion having a smaller cross sectional area than adjacent portions of the conductor. By integrally forming the overheat protection portions on the conductors, no extra overheat protection device is required. Preferably, the overheat protection portion has a bent structure. The bent structure may be U-shape, Z-shape, M-shape or wave-shape. The bent structure can increase the anti-shock capability of the conductor and shorten the response time of the overheat protection portion.
