Patent ID: 8302874

Claim:
A waste heat reusing system, comprising: a first intake apparatus to receive waste heat from a heat generating device; a second intake apparatus to receive cold air from environment; a heater to heat the waste heat received by the first intake apparatus; a first outlet apparatus to output the waste heat when the temperature of the waste heat reaches a preset temperature value, the first outlet apparatus comprising: a first outlet; a first valve; and a first temperature sensor to detect the temperature of the waste heat of the first outlet; a second outlet apparatus venting the waste heat and the cold air before the first outlet apparatus is turned on; and a controller storing the preset temperature value, and receiving the temperature data of the waste heat detected by the first temperature sensor, wherein when the detected temperature by the first temperature sensor is greater than the preset temperature value, the controller controls the airflow capacity of the waste heat inputted into the first intake apparatus to be reduced and controls the airflow capacity of the cold air inputted into the second intake apparatus to increase, therefore, the temperature of the waste heat inputted into the first intake apparatus is reduced; wherein when the detected temperature by the first temperature sensor is less than the preset temperature value, the controller controls the heater to heat the waste heat inputted into the first intake apparatus, when the detected temperature by the first temperature sensor reaches the preset temperature value, the controller controls the first valve to open, to output the waste heat.
