Abstract

A heat recycling system for recycling heat from an electronic device includes a pipe with an inside tube and an outside tube coiled around the inside tube. The inside tube is connected to a first airduct to receive heated air from the electronic device. The outside tube is to receive cooling air from outside. A number of thermoelectric modules are formed in walls of the inside tube. A first end of each thermoelectric module is inserted into the outside tube, and a second end of each thermoelectric module is inserted into the inside tube. Therefore, the number of thermoelectric modules may generate current.
