Description
Technical field
The present invention relates to a kind of wave filter, and in particular to based on arrowband, the high communication apparatus suppressed.
Background technology
Wave filter is a kind of that useful signal is as undamped as possible by the RF device decayed as far as possible to garbage signal
Part；The general signal transmitting and receiving device or circuit part for being located at communication equipment, to realize the selection index system of communication device signal.
Generally, wave filter is mainly made up of filter cavity and cover plate, and multiple resonant rods are provided with filter cavity body, is tuned
It is relative with the resonant rod that screw rod one end penetrates cover plate, by adjust instrument adjust the distance between tuning screw and resonant rod with
Reach required RF index.
Because the exact requirements and wave filter that select frequency have the reasons such as temperature drift in itself, often needed in work
Ensure that the temperature in cavity body filter can not be too high, and cavity body filter has certain operating power in itself, therefore, one
In a little radio frequency operation units, such as Remote Radio Unit, the cavity body filter with radiator structure, the cavity with radiator structure are often used
Wave filter in order to meet the needs that cavity body filter radiates in itself and setting radiating shell and being made of one of cavity body filter
It is standby, very early before way be：Cavity body filter is screwed on one block of heat sink, this way can be with simple realization
The combination of heat sink and cavity body filter, but due in this connected mode cavity body filter and heat sink exist between air
Gap so that heat-transfer effect is unsatisfactory, does not reach radiating effect substantially.
The content of the invention
The technical problems to be solved by the invention are that cavity body filter has the air gap with heat sink so that heat-transfer effect
It is unsatisfactory, substantially do not reach radiating effect, and it is an object of the present invention to provide based on arrowband, the high communication apparatus suppressed, solve cavity
There is the air gap in wave filter and heat sink so that heat-transfer effect is unsatisfactory, the problem of not reaching radiating effect substantially.
The present invention is achieved through the following technical solutions：
Included based on arrowband, the high communication apparatus suppressed, including rectangular filter, the rectangular filter by four side plates
With the cavity in bottom plate besieged city, in addition to the top plate matched with cavity, the top plate sets the top plate frame with fastener, the cavity bag
The limitting casing matched with top plate frame is included, the neck matched with fastener is set on the limitting casing；The top plate sets aperture, described
Small hole number is at least 5, is evenly distributed on top plate；The limitting casing inframe sets cotton layer, and the cotton layer is provided with framework,
Including two layers of burlap net, steel wire is set between the burlap net；Cunning with cotton frames match is set on the framework of limitting casing
Groove, and it is movable frame to set side, is connected with other framework latches.The air gap be present with heat sink in cavity body filter,
So that heat-transfer effect is unsatisfactory, do not reach radiating effect substantially, what traditional wave filter used is all integral seal structure,
The top drilling that the present invention uses for indoor wave filter, the setting of aperture not only increase radiating effect from area of dissipation,
And directly connect outside wave filter, degree has been the high temperature of comparison more than 30 for room temperature, so also can in computer room
Air-conditioning is set, traditional closing wave filter, 60 DEG C of internal temperature, institute can be reached in the computer room of 40 DEG C or so of an air-conditioning constant temperature
Open wave filter is used with the present invention, on the premise of heat dispersal situations solve, present invention employs lower section corresponding to aperture
Cotton layer is set, and cotton layer is made up of burlap net and wire netting, so serves the effect for preventing grieshoch, due to breathing freely for burlap
Performance is fabulous, so while dust is prevented, will not stop the transmission of heat, further, improves filtering in this way
The radiating of device, this cotton layer can be changed, and cost is low, Reusability after can cleaning.
The limitting casing is rectangular frame, and two necks are respectively provided with per side；The top plate frame is rectangular frame, per side
It is respectively provided with two fasteners.Further, the preferred scheme as the present invention.
The chamber outer wall sets anticorrosive coat.Further, the preferred scheme as the present invention.
The chamber outer wall sets insulating barrier, further, the preferred scheme as the present invention..
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention increases radiating effect based on arrowband, the high communication apparatus suppressed, the setting in hole from area of dissipation, even
It can reach consistent with indoor temperature outside bandpass filter；
2nd, the present invention is made up of burlap net and wire netting, so played based on arrowband, the high communication apparatus suppressed, cotton layer
The effect of grieshoch is prevented, because the permeability of burlap is fabulous, so while dust is prevented, the biography of heat will not be stopped
Pass；
3rd, the present invention can be changed based on arrowband, the high communication apparatus suppressed, individual cotton layer, and cost is low, Ke Yiqing
Reusability after washing.
