Abstract: Provided in the present application are an energy recovery apparatus and an electronic device. The energy recovery apparatus includes a thermoelectric conversion unit, a heat dissipation component, a power storage unit, and a heating unit, where the thermoelectric conversion unit includes a first thermoelectric material and a second thermoelectric material, a first end of the first thermoelectric material is connected to a first end of the second thermoelectric material, and the first end of the first thermoelectric material and the first end of the second thermoelectric material are in contact with the heating unit; the heat dissipation component includes a heat pipe, the heat pipe includes a first end and a second end, and the second end of the heat pipe is in contact with a second end of the first thermoelectric material and a second end of the second thermoelectric material.

Abstract: Embodiments of the present application relate to a method and device for defending against website attacks. The method includes obtaining a traffic threshold value corresponding to a target IP address, determining whether real-time visitor traffic for the target IP address exceeds the traffic threshold value, and handling visitor traffic for the target IP address based at least in part on whether the real-time visitor traffic for the target IP address exceeds the traffic threshold value, wherein the handling incoming visitor traffic for the target IP address based at least in part on whether the real-time visitor traffic for the target IP address exceeds the traffic threshold value includes, in the event that the real-time visitor traffic for the target IP address exceeds the traffic threshold value, configuring a blackhole route for the target IP address, and redirecting the incoming visitor traffic for the target IP address to the blackhole route.
