Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment：As shown in Figs. 1-2, including shell 1,1 bottom of the shell are provided with pedestal 4, are set inside the pedestal 4
It is equipped with power amplifier ontology 6,6 side of power amplifier ontology is provided with power supply 3, signal transceiver 2 is provided on the power supply 3, described
6 top surface of power amplifier ontology covers one layer of silicone grease heat dissipating layer 9, and radiating fin 10 is provided on the silicone grease heat dissipating layer 9, described to dissipate
Setting is both provided with micro-machine 8, the micro-machine there are two thermovent 15 in two thermovents 15 on hot fin 10
It is connected with shaft 12 on 8, flabellum 11 is provided in the shaft 12, Air Filter 7, the shell are provided on the thermovent 15
