US Patent 7190576 Internally disposed cooling device for electronic apparatus

An internally disposed cooling device is provided. The cooling device includes a cooling member and a docket member. The cooling member includes a first cooling unit, a second unit and a cryogenic element. The cryogenic element has a cold surface that contacts the first cooling unit, and a hot surface that contacts the second cooling unit. Since the cold surface of the cryogenic element has a temperature much lower than that of the room temperature, the first cooling unit can thus produce cold and dry air to cool down the electronic apparatus. Meanwhile, the second cooling unit is employed to dissipate heat generated from the cryogenic element.
