Since outdoor base station covering power is limited, tunnel, subway, underground commercial center, entertainment city, parking lot and hotel are write
Signal blind zone is frequently present of in some closed buildings such as word building.Digital optical fiber direct station is by digital processing, number
The means such as word optical transport and software and radio technique, base station radio-frequency part is zoomed out, service multiple cells one kind it is completely new be
System solution, can effectively solve blind area signal covering problem.
Digital optical fiber direct station cabinet generally considers heat dissipation and indoor and outdoor use environment problem, generallys use metal chassis.
Cabinet is made of upper cover, middle part cabinet, cooling fin three parts.Usually by radio frequency power amplification modules, duplexer, number inside repeater
Ifd module, the composition such as power module.Each module is first installed in an individual structural box under normal conditions, box body one
As manufactured by aluminum casting, each box body is installed on cabinet inside corresponding position again.This traditional mode internal box quantity compared with
It is more, it is unfavorable for the simplification and miniaturization of casing structure.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of compact-sized, good heat dissipation effect
Digital optical fiber direct station cabinet.
The purpose of this utility model is achieved through the following technical solutions: a kind of digital optical fiber direct station cabinet, it is wrapped
Upper cover, middle part cabinet and cooling fin are included, the upper cover and middle part cabinet are all made of cold-rolled steel sheet bending and forming, and upper cover passes through hinge
Structure is connected with middle part cabinet, and the side on the cabinet of middle part is provided with multiple aerial lug holes, and the other side of middle part cabinet is provided with
Ventilation fan hole, the lower part of middle part cabinet and cooling fin are attached by bolt, and cooling fin bottom outer surface is provided with several
For radiating fin to enhance heat sinking function, cooling fin is provided with modular cartridge, modular cartridge and cooling fin in one middle side part of cabinet inner surface
Using the one-time formed integral structure of die casting aluminium, the modular cartridge inner route clapboard is divided into several cavity blocks, adjacent separator it
Between be equipped with partition and be interrupted, modular cartridge is towards being additionally provided with wind-guiding fin on one side surface of ventilation fan hole.Cooling fin is in wind-guiding
Fan is additionally provided between fin and ventilation fan hole.
Further, the modular cartridge heat release hole is evenly provided on each end face of modular cartridge；
Further, the fan is fixed by screws on heat sink.
The utility model has the advantage that
Modular cartridge is cast into cooling fin and is integrated, radio frequency power amplification modules and data intermediate frequency module are no longer distinguished
It is separately installed to improve box body structure in an individual structural box, be conducive to the simplification and miniaturization of casing structure, section
About material and processing cost, power amplifier module is directly installed on cooling fin top, has good heat dissipation effect.
