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.

A heat dissipating device has a conductor holder and a heat conductor. The conductor holder is securely attached to the CPU base and has a through hole. The heat conductor is securely connected to the through hole in the conductor holder and contacts with the CPU. The heat conductor comprises multiple heat conductive elements made of a material with good heat conductivity. One end of the heat conductive elements are twisted together to form a bound section on the first end of the heat conductor. The other end of each heat conductive element is far away from the other element so as to form an expansion section on a second end of the heat conductor. In such an arrangement, the heat generated by the CPU can be efficiently dissipated from the expansion section of the heat conductor.
