Description
Technical field
The present invention relates to electronic applications, and in particular to the excess temperature and abnormality alarming device of power amplifier module.
Background technology
Power amplifier is the significant components of dispensing device in communication system.Power amplifier is used for the final stage of emitter,
Effect is that modulated wave signal is carried out into power amplification, to meet the requirement of transmit power, then radiates it into sky by antenna
Between, it is ensured that the receiver in certain area can receive satisfied signal level, and not disturb the communication of adjacent channel.
Two kinds of narrow-band high frequency power amplifier and wideband high-frequency power amplifier, narrow-band high frequency work(are divided into by the width of its working band
Rate amplifier generally using the frequency selection circuit that is acted on frequency-selective filtering as output loop, therefore also known as Tuned Power Amplifier or
Tuned power amplifier；The output circuit of wideband high-frequency power amplifier is then line transformer or other Broadband Matchings electricity
Road, therefore also known as nonresonant power amplifier.
Power amplifier is higher due to power output, and the heat that it is produced is larger, if do not dissipated to power amplifier
Heat treatment, the heat constantly accumulated is likely to cause the circuit or device failure of power amplifier, in the prior art, work(
Rate amplifier is generally radiated using metal shell, but metal shell is to cover power amplifier to wrap up all the time, heat
Amount carries out autonomous heat transfer by shell, and radiating rate is very slow.
The content of the invention
The technical problems to be solved by the invention are that heat carries out autonomous heat transfer by shell, and radiating rate is very slow, mesh
The excess temperature and abnormality alarming device that are to provide power amplifier module, set up heat abstractor, improve radiating efficiency.
The present invention is achieved through the following technical solutions：
The excess temperature and abnormality alarming device of power amplifier module, including power amplifier shell, in addition to inner side heat-absorbing water pipe and outside are released
Hot-water line, the inner side heat-absorbing water pipe is arranged on power amplifier inner surface of outer cover, and the outside heat release water pipe is arranged on outside power amplifier shell
Surface；The inner side heat-absorbing water pipe includes inner side heat-absorbing water pipe entrance, inner side heat-absorbing water pipe middle part, the outlet of inner side heat-absorbing water pipe,
The outside heat release water pipe includes outside heat release pipe inlet, outside heat release water pipe middle part, outside heat release pipe outlet, described interior
Side heat-absorbing water pipe entrance is connected with outside heat release pipe outlet, and the inner side heat-absorbing water pipe outlet connects with outside heat release pipe inlet
Connect；The inner side heat-absorbing water pipe middle part surface is additionally provided with temperature sensor and alarm module.
Further, it is snakelike in the middle part of the heat-absorbing water pipe of inner side to be arranged on power amplifier inner surface of outer cover；In the outside heat release water pipe
Portion is snakelike to be arranged on power amplifier outer surface of outer cover.
Further, temperature sensor and alarm module are connected on microcontroller, and the microcontroller is also connected with
There are reset circuit, keyboard, display.
Further, signal processing module and AD are also connected with turn on the circuit between temperature sensor and microcontroller
Modular converter.
Certain space is left between the power amplifier module of power amplifier shell and inside, power amplifier module operationally can
Heat is constantly produced, heat is constantly accumulated in power amplifier enclosure, temperature rises, a part of heat can be dissipated by power amplifier shell
It is dealt into extraneous air, but is due to that power amplifier is wrapped in by power amplifier shell all the time, formation is confined space, is passed through
The heat that shell is independently distributed is very limited；Therefore, between power amplifier module of the present invention using power amplifier shell and inside
Space, power amplifier shell inner surface setting on the inside of heat-absorbing water pipe, current from inner side heat-absorbing water pipe entrance enter, pass through inner side
In the middle part of heat-absorbing water pipe, current constantly absorb the heat formation high-temperature water of power amplifier enclosure, and high-temperature water passes through inner side heat-absorbing water pipe
Outlet outflow, into outside heat release pipe inlet, so as to flow into the middle part of the heat release water pipe of outside, high-temperature water is in the heat release water pipe of outside
Heat is directly released into air in portion, high-temperature water becomes normal-temperature water again again, continued cycling through.It is distributed in the middle part of the heat-absorbing water pipe of inner side
The temperature sensor on surface detects the temperature of power amplifier module, if exception occurs in temperature, will pass through microcontroller and trigger report
Alert module, is easy to position the power amplifier module of failure in time, it is to avoid some unnecessary losses.
The present invention compared with prior art, has the following advantages and advantages：The present invention using power amplifier shell with it is interior
Space between the power amplifier module in portion, the heat-absorbing water pipe on the inside of the setting of power amplifier shell inner surface, passes through the current of flowing
The heat on the inside of power amplifier shell is absorbed, accelerated heat is distributed.
