2041 one end of warmware is connect by the aperture of shielding case 206 with heating device 203,2041 other end of heat-conducting piece and even heat plate
2042 connections, the heat that heating device 202 generates are transferred to even heat plate 2042 by heat-conducting piece 2041, and 2042 area of even heat plate is big
And uniformity of temperature profile, with cross-ventilation heat exchange efficiency relative to directly higher, the heat dissipation effect with 202 heat convection of heating device
More preferably.Heat-conducting piece 2041 is copper pipe in the present embodiment, and one end of 2042 outer surface of even heat plate is connected with copper pipe, reaches thermal energy
From effect of the uniformly dispersing on even heat plate 2042；Even heat plate 2042 is made of metal material in the present embodiment, such as aluminium or copper
Alloy.
In some embodiments, as shown in Figure 10, radiating piece 204 is the shielding case 206 being arranged above heating device 202,
The heat that heating device 203 generates is transmitted to outside shielding case 206 by shielding case 206, since heat dissipation tank 202 is covered with radiating piece
204 and radiator fan 205, i.e. the heat that generates of heating device 202 is by 206 delivery value heat dissipation tank 203 of shielding case, in order to protect
The efficiency of 202 heat transfer of heating device is demonstrate,proved, the upper surface of shielding case 206 includes at least an aperture, the size of certain aperture
It can be adjusted flexibly according to the actual situation with position.
In the present embodiment, the air inlet of heat dissipation tank 203 and air outlet can be set in terminal enclosure, optionally, phase
To the two sides of shell are arranged in, such as it is separately positioned on the left and right sides of shell or up and down on two sides or front and rear sides.Certainly,
Also it can be set at the different location of the same side, it specifically can flexible setting according to the actual situation.Such as air inlet and outlet air
Mouth can use the position of opening such as the earpiece holes being arranged in terminal enclosure, horn mouth, charge port, the hole USB substitution, it is of course possible to logical
It crosses and individual aperture is set as air inlet and air outlet, details are not described herein.
