Heat recycling system

Abstract

A heat recycling system for recycling heat from an electronic device includes a first tube, a second tube, and a plurality of thermoelectric modules. The first tube is used to receive heated air from the electronic device. The second tube is used to receive cooling air from outside. A first end of each thermoelectric module is inserted into the first tube, and a second end of each thermoelectric module is inserted into the second tube. Therefore, the number of thermoelectric modules may generate current.

         2 . The heat recycling system of  claim 1 , further comprising an outside tube coiled around the second tube, the second is an inside tube, and the first tube is a space between the outside tube and the inside tube. 
     
     
         3 . The heat recycling system of  claim 2 , further comprising a first airduct connected to the electronic device to receive heated air from the electronic device, wherein the outside tube is connected to the first airduct to receive the heated air with the space; and wherein the plurality of thermoelectric modules are formed in walls of the inside tube. 
     
     
         4 . The heat recycling system of  claim 3 , wherein the storage apparatus is a capacitor. 
     
     
         5 . The heat recycling system of  claim 3 , further comprising a power circuit connected to the storage apparatus. 
     
     
         6 . The heat recycling system of  claim 2 , wherein the inside tube comprises an air inlet, and the outside air enters into the inner space of the inside tube through the air inlet of the inside tube. 
     
     
         7 . The heat recycling system of  claim 6 , further comprising an air controller, wherein the air controller comprises a temperature sensor, a second air inlet, and a first air outlet; wherein the outside tube comprises a second air outlet, the second air inlet of the air controller is connected to the second air outlet of the outside tube, and the temperature sensor senses temperature of airflow in the air controller to open or close the first air outlet of the air controller correspondingly. 
     
     
         8 . The heat recycling system of  claim 7 , further comprising a second airduct, wherein the air controller further comprises a third air outlet, a first end of the second airduct is connected to the third air outlet of the air controller, a second end of the second airduct is connected to the electronic device; wherein upon the condition that the temperature of the airflow in the air controller is greater than a predetermined value, the air controller opens the first air outlet to allow the airflow to enter the open space, upon the condition that the temperature of the airflow in the air controller is less than the predetermined value, and the air controller opens the third air outlet to allow the airflow to enter into the second airduct. 
     
     
         9 . The heat recycling system of  claim 2 , further comprising an air controller, wherein the air controller comprises a temperature sensor, an air inlet, and a first air outlet, wherein the inside tube comprises a second air outlet, the air inlet of the air controller is connected to the second air outlet of the inside tube, and the temperature sensor senses temperature of airflow in the air controller to open or close the first air outlet of the air controller correspondingly. 
     
     
         10 .
