The position of hot fin is located at below the notch of cabinet；Rear wall is extended to downwards position and the radiating fin phase below notch
It is right；Heat conduction boss one end between adjacent two panels radiating fin, other end horizontal connection to rear wall be extended to downwards notch with
Under position, by by radio frequency unit be provided with radiating fin position exposure in the environment, can promote to radiate, and reduce sky
Adjust energy consumption.
The heat conduction boss is preferably disposed on the regional center that radiating fin is formed, close to the power amplifier chips of radio frequency unit
Position.
Wherein, cabinet air conditioner is installed, it is 52~55 DEG C that cabinet air conditioner, which sets start-up temperature scope, is stopped in the cabinet door
Operating temperature range is 45~50 DEG C；Cabinet need not set thermal insulation board, be easy to function of environment heat emission.
Wherein, the heat conduction boss is fixed on rear wall by being spirally connected or riveting.
Wherein, the rear wall is aluminum heat sink or common iron plate.
Wherein, the heat conduction boss is aluminum, highly less than or equal to the distance between adjacent two panels radiating fin, width
Be slightly less than the width of radiating fin, heat conduction boss between adjacent two panels radiating fin, and be in contact with radiating fin so as to
Heat transfer.
Wherein, it is provided with heat conductive silica gel between the heat conduction boss and radiating fin.
Wherein, waterproof adhesive tape is provided between the cabinet and cabinet door, waterproof adhesive tape is provided between radio frequency unit and notch.
Beneficial effect：
1st, heat caused by the application radio frequency unit power amplifier chips is transmitted to radio frequency unit fin, is divided into two-way：All the way
Radiating fin whole surface is diffused into, and another way gives cabinet rear wall by heat conduction lands conduct, then heat is radiated by rear wall
It is dispersed into air, because rear wall area is much larger than radio frequency unit radiating fin area, so thermal resistance is small, temperature rise is small.
2nd, the application rack is in sealing state, meets the requirement of shelter such as waterproof and dustproof, while can play good dissipate again
Heat effect, radiator structure is simple, and occupancy enclosure interior is small, especially suitable for mini-system, especially single radio frequency unit
Wall mount cabinet.
