Since the copper heat conduction pipe 133 has a limited heat conduction property, the copper heat conduction pipe 133 is filled with a heat conduction medium in order to further improve the heat conduction property of the copper heat conduction pipe 133. Meanwhile, in order to facilitate filling and discharging of the heat transfer medium, and to sufficiently collect heat of the device chamber 1021 and perform heat exchange in the second air chamber 1022, both ends of each copper heat transfer tube 133 are respectively exposed to the outside of both facing-away sides of the first fin laminated layer 131 and the second fin laminated layer 132.
