Description
Technical field
The present invention relates to electronic applications, and in particular to a kind of temperature detection prior-warning device of power amplifier.
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 temperature detection prior-warning device for being to provide a kind of power amplifier, set up heat abstractor, improve radiating efficiency.
The present invention is achieved through the following technical solutions：
A kind of temperature detection prior-warning device of power amplifier, including power amplifier shell, it is characterised in that also dissipated including water cooling
Hot cell, the water-cooling unit includes inner side heat-absorbing water pipe and outside heat release water pipe, and the inner side heat-absorbing water pipe is arranged on
Power amplifier inner surface of outer cover, the outside heat release water pipe is arranged on power amplifier outer surface of outer cover；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 include outside heat release water
Tube inlet, outside heat release water pipe middle part, outside heat release pipe outlet, the inner side heat-absorbing water pipe entrance go out with outside heat release water pipe
Mouth connection, the inner side heat-absorbing water pipe outlet is connected with outside heat release pipe inlet；The inner side heat-absorbing water pipe middle part surface is also
It is provided with temperature sensor and alarm module；Multiple water-cooling units are provided with one power amplifier shell, each water cooling dissipates
It is separate between hot cell.
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.
Further, the length of the inner side heat-absorbing water pipe of each water-cooling unit and the length of outside heat release water pipe is not
More than 4 times of power amplifier outer cover length.
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.
When water-cooling unit number set it is reasonable, its number scope within 5, it is ensured that water flow refrigerating imitate
Preferably, because the density of water-cooling unit is larger, the replacing speed of current can faster, since the heat-absorbing water pipe entrance of inner side for fruit
The heat that current absorb will not transport follow-up power amplifier case surface, so ensure that inner side heat-absorbing water pipe exit portion
The radiating effect of power amplifier shell.
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.
