[0012] like Figure 1 As shown, an embodiment of the present invention provides a reader / writer that is easy to assemble and dissipate heat, including a face shell 1, an inner wall of the face shell 1 is provided with a sliding rib 2, a mainboard 7 is fixedly installed inside the face shell 1 by M2 screws, the surface of the face shell 1 is slidably connected to a heat dissipation shell 4, and the mainboard 7, the face shell 1 and the heat dissipation shell 4 are combined with each other using M2 screws 3, a side sliding opening 11 is provided on the side of the heat dissipation shell 4, a spring gasket 5 and a fixing nut 6 are provided on the side of the heat dissipation shell 4, the surface of the mainboard 7 has a mainboard exposed copper area 8, and a thermal conductive silicone pad 10 is provided at the position of the mainboard exposed copper area 8. The bottom surface of the heat dissipation shell 4 is fixed to the mainboard 7 by six M2 screws 3, the middle two M2 screws 3 are in contact with the thermal conductive silicone pad 10, and the surface of the mainboard 7 is provided with an M2 patch copper column 9.

[0013] Working principle: When assembling this design, first insert the motherboard 7 into the face shell 1, tighten the six M2 screws 3, and then stick the thermal conductive silicone pad 10 to the exposed copper area 8 of the motherboard. The thermal conductive silicone pad 10 has a large area and high thermal conductivity, and plays a good heat conduction role. The heat dissipation shell 4 is made of aluminum alloy with high thermal conductivity. Align the opening of the heat dissipation shell 4 with the face shell 1 so that it is pushed into the face shell 1 along the sliding rib 2. The heat dissipation shell 4 presses the thermal conductive silicone pad 10, and the heat of the motherboard 7 is transferred to the aluminum alloy surface through the thermal conductive silicone pad 10. The heat is dissipated through thermal radiation and convection to reduce the temperature of the motherboard 7. The bottom of the heat dissipation shell 4 is locked together with the motherboard 7 by six M2 screws 3. The two middle screws can also press the thermal conductive silicone pad 10 to increase the heat conduction effect. Finally, lock the eight spring washers 5 and fixing nuts 6 to further increase the fixing effect of the motherboard 7 and the heat dissipation shell 4.
