Description
Technical field
The present invention relates to power amplifiers, can Split assembled power amplifier more particularly, to one kind.
Background technique
Currently, existing power amplifier is a non-removable whole structure mostly.If Authorization Notice No. is CN
The patent document of 202696542 U disclosed modular professional power amplifier, the power amplifier include panel, shell and control system
System, the control system of the power amplifier is divided into input and control panel, rectifying and wave-filtering and voltage change plate, display board, power input board, function
It puts plate five individual module this five modules to be independently arranged, and is electrically connected, wherein display panel module is set to panel
On, control plate module, rectifying and wave-filtering and voltage change plate module, power input plate module and power amplifier plate module and are then set to shell
It is interior, positioned at the middle part of shell；There are two air ducts for the two sides setting of enclosure interior.Although above-mentioned power amplifier uses modular design,
It is combined modules can as needed, convenient for the concrete application of power amplifier, however, modularized design still is limited to power amplifier
Inside, there is no power amplifier itself is directed to, power amplifier itself is still a non-removable whole structure, and the application of power amplifier is still
With limitation.
Currently, no matter power amplifier number of channels is how many or the complexity of power amplifier structure is simple, existing power amplifier is general
It is all mounted in 19 cun of cabinets of a standard.But often number of channels is less for power amplifier using the above structure, moreover,
If the product structure of power amplifier is relatively simple, the component in cabinet will be seldom, and the space in cabinet is not fully used, makes
At waste.
For this reason, it is necessary to study a kind of power amplifier that can rationally utilize chassis space.
Summary of the invention
The purpose of the present invention is to provide it is a kind of it is simple and compact for structure, easy to use and flexible, can rationally utilize chassis space
Power amplifier.
To achieve the goals above, the present invention adopts the following technical scheme:
One kind can Split assembled power amplifier, particularly, including shell and several power amplifiers that can work independently；The shell is cylinder
Body structure, the interior positioning component for being used to fix power amplifier equipped with several of the shell；The positioning component includes at least two locating piece, and 2
Module channels are formed between a locating piece；Power amplifier is mounted in the module channels；It is additionally provided on shell for fixing power amplifier
Limit edge；The end of shell is arranged in the limit edge, and lid closes on the shell.
The principle of the present invention is as follows:
Originally can Split assembled power amplifier include several power amplifiers, each power amplifier can work independently.The quantity of power amplifier can be one
It is a, it is also possible to multiple.Each power amplifier is mounted in corresponding module channels.Staff can select one according to actual needs
Or multiple suitable power amplifiers of rated power.Multiple power amplifiers are mounted in corresponding module channels and are concatenated, and are that originally can divide
Body combine power amplifier general power, make originally can Split assembled power amplifier can flexible adaptation various application occasions, it is easy to use.
Each power amplifier can be arranged inside the shell in vertical juxtaposition or inclined juxtaposition.Because each function power amplifier is mounted on mould
It in block channel, is realized and is separated by positioning component between each power amplifier, by there are certain spacing between each power amplifier, convenient for each power amplifier
Heat distributes.
The end of shell is arranged in limit edge, for fixing power amplifier.To avoid power amplifier from skidding off through the other end of shell, position
On block can be equipped with can opposite shell autorotation baffle, the baffle and limit edge be respectively set at the both ends of shell.Power amplifier is pacified
After module channels, flap shutter can be such that power amplifier is fixed in module channels.
Since multiple power amplifiers originally can be equipped in the shell of Split assembled power amplifier, for avoid can Split assembled power amplifier volume mistake
Greatly, the design of the structure of power amplifier should be more compact, in this regard, following structures can be used in power amplifier: closing on pedestal including pedestal and lid
Top cover；Component cavity is equipped in the pedestal；The pedestal is equipped with front panel and rear panel, is equipped on the front panel and rear panel
The heat release hole communicated with component cavity；Audio substrate, substructure for electrical device and heat sink are from top to bottom successively arranged in the component cavity；
The audio substrate is equipped with audio conversion module and audio output module close to rear panel, audio substrate；The substructure for electrical device
Through entire component cavity, substructure for electrical device is equipped with and is successively arranged power module, transformer module and rectification filtering module, should
Power module is close to front panel, and rectification filtering module is in the middle part of component cavity；The heat sink runs through entire component cavity, and radiate hole location
In the lower section of heat sink.Power amplifier using the above structure, can place 4 or 4 or more power amplifiers in 19 cun of cabinets of standard, use
Person can assemble the suitable power amplifier of quantity according to actual needs in cabinet, and use is more convenient.
To provide the heat dissipation effect of power amplifier, it can be equipped with blower module on front panel, accelerate the sky between heat sink and pedestal
Gas convection current.In addition, can also be equipped with several radiating fins on heat sink, the radiating fin is towards the bottom of pedestal, to improve
The radiating efficiency of heat sink.
To avoid each module volume because being arranged on substructure for electrical device excessive, audio substrate is caused to be difficult to close to electronics
Device substrate keeps the volume of power amplifier excessive, and clearance position can be equipped on the audio substrate.The biggish mould of substructure for electrical device upper volume
In the embeddable clearance position of block, to guarantee that audio substrate can reduce the volume of power amplifier to the maximum extent close to substructure for electrical device.
Handle member can be also equipped on the power amplifier, so that operator's replacement originally can Split assembled function convenient for extracting power amplifier
Put interior power amplifier.
The present invention has many advantages, such as simple and compact for structure, good heat dissipation effect, easy to use and flexible.
