Description
Technical field
The present invention relates to electronic applications, and in particular to the cooling system of universal power amplifier module.
Background technology
Universal power amplifier is the significant components of dispensing device in communication system.Universal power amplifier is used for emitter
Final stage, effect is that modulated wave signal is carried out into power amplification, to meet the requirement of transmit power, then by antenna by its spoke
It is mapped to space, it is ensured that the receiver in certain area can receive satisfied signal level, and not disturb adjacent channel
Communication.Two kinds of narrow-band high frequency power amplifier and wideband high-frequency power amplifier are divided into by the width of its working band, it is narrow
With high frequency power amplifier generally using the frequency selection circuit that is acted on frequency-selective filtering as output loop, therefore also known as tune power
Amplifier or tuned power amplifier；The output circuit of wideband high-frequency power amplifier is then line transformer or other broadbands
Match circuit, therefore also known as nonresonant power amplifier.
Universal power amplifier is higher due to power output, and the heat that it is produced is larger, if do not amplified to universal power
Device carries out radiating treatment, and the heat constantly accumulated is likely to cause the circuit or device failure of universal power amplifier,
In the prior art, universal power amplifier is generally radiated using metal shell, and metal shell surface is provided with bumps not
Flat paster, so as to realize that increase area of dissipation is radiated.But, in actual use, universal power amplifier makes
Other devices are also closely provided with around number more than one, and universal power amplifier, are so caused in smaller space
Heat be still present in around universal power amplifier, such radiating effect is simultaneously bad.
The content of the invention
The technical problems to be solved by the invention are that paster radiating effect of the prior art is bad, it is therefore intended that provide logical
With the cooling system of power amplifier module, the heat of universal power amplifier is effectively spread out, universal power is reduced
The operating temperature of amplifier.
The present invention is achieved through the following technical solutions：
The cooling system of universal power amplifier module, including universal power amplifier, in addition to lower floor's aquaporin, shell
Radiated iron plate, Water flow circulation device, shell, and the universal power amplifier external is covered by shell and wrapped up, the shell table
Face is provided with shell radiating iron plate, and the shell radiating iron plate is vertically arranged in case surface, and marshalling, and adjacent is outer
Space is left between shell radiating iron plate；Lower floor's aquaporin, which is covered on the downside of case surface, lower floor's aquaporin, to be left uniformly
Projection, raised position and shell radiating iron plate between space match；Upper strata is provided with the upside of lower floor's aquaporin
Aquaporin, upper strata aquaporin is covered in lower floor's aquaporin surface；The two ends of the upper strata aquaporin and lower floor's aquaporin two ends point
Do not connected by a Water flow circulation device correspondence.
In the prior art by setting shell radiating iron plate increasing heat radiation area, the present invention is on the surface of shell radiating iron plate
Upper strata aquaporin and lower floor's aquaporin are set again, and upper strata aquaporin and lower floor's aquaporin, can be with by Water flow circulation device insertion
Form water circulation passage.When two Water flow circulation device work, the water in upper strata aquaporin and lower floor's aquaporin is flowed
Dynamic, the water in lower floor's aquaporin is in close contact with shell and shell radiating iron plate, and current radiate shell and shell iron plate
In temperature take away, coolant-temperature gage in lower floor's aquaporin rise, upper strata aquaporin can be by the face that is contacted with lower floor aquaporin
Product absorbs the temperature of a part of lower floor's aquaporin, while the water in lower floor's aquaporin can be flowed into upper water by Water flow circulation device
In passage, radiated in the aquaporin of upper strata, the water at low temperature in the aquaporin of upper strata enters in lower floor's aquaporin and absorbed before
Heat.Because the specific heat capacity of water is very big, its heat absorbed is a lot, and such heat can make a brief stay in water, just
Heat around universal power amplifier is transmitted to large space, is conducive to the radiating of universal power amplifier.
Further, lower floor's aquaporin is fixed with shell radiating iron plate by projection with the mutual clamp in space.Pass through projection
Clamp are carried out with gap, the shell of aquaporin and universal power amplifier can not be damaged.
Further, upper strata aquaporin is made with lower floor aquaporin of hard glass, and two tables of upper strata aquaporin
Thickness between face is twice of most narrow thickness between two surfaces of lower floor's aquaporin.The volume of upper strata aquaporin is more than lower floor's water
The volume of passage, high-temperature water can make in the aquaporin of upper strata it is longer stop, be easy to dispersing for heat in high-temperature water.
Further, Water flow circulation device uses small propeller, and two small propeller driving directions are simultaneously
Along what is driven clockwise or counter-clockwise.
Further, Water flow circulation device uses small pump.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention is very big using the specific heat capacity of water, and its heat absorbed is a lot, and such heat can be done in water
Short stay, is easy to the heat around universal power amplifier to be transmitted to large space, is conducive to universal power amplifier
Radiating；
2nd, the volume of aquaporin at the middle and upper levels of the invention is more than the volume of lower floor's aquaporin, and high-temperature water can be in upper strata aquaporin
It is middle make it is longer stop, be easy to dispersing for heat in high-temperature water.
