Description
Technical field
The present invention relates to electronic applications, and in particular to a kind of radiating module of general power amplifier.
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 one
The radiating module of general power amplifier is planted, the heat of universal power amplifier is effectively spread out, universal power amplifier is reduced
Operating temperature.
The present invention is achieved through the following technical solutions：
A kind of radiating module of general power amplifier, including shell, in addition to radiating iron plate, space, channel interface, water storage appearance
Device, capillary water pipe, the case surface, which is vertically arranged between radiating iron plate arranged in a uniform, adjacent radiating iron plate, to be left
Even space, the capillary water pipe has many, in the space for being uniformly arranged radiating iron plate formation, the axis and level of capillary water pipe
Face is parallel；Capillary water pipe laid out in parallel, the surface on the surface for the iron plate that radiates and shell is covered；The tank is arranged on
On shell end face corresponding to the two ends of space；The two ends of all capillary water pipes are passed through in the corresponding tank in both sides；With
A shell axis parallel to capillary water pipe is boundary, and the capillary water pipe two ends of axis side connect a flood respectively
Pipe, big pipe is passed through in corresponding tank, and the capillary water pipe two ends of axis opposite side connect a big pipe respectively, greatly
Water pipe is passed through in corresponding tank.
Further, the width in space is in the range of 1cm~10cm.
Further, the diameter of capillary water pipe is less than or equal to 1cm.
Further, micro pump is provided with the tank of both sides, two water pumps are separately positioned on not corresponding
On big pipe.
Radiating iron plate on and shell on uniform fold marshalling capillary water pipe, due to capillary water pipe diameter compared with
It is small, the heat that shell and radiating paster are sent can be received faster, and current form high-temperature water, and capillary water after absorbing heat
The speed of current in pipe, can be defeated by a big pipe in the tank by the high-temperature water in capillary water pipe faster
Deliver in tank, then because capillary water pipe is thinner, can be also dispersed into timely by the minor heat that current absorb
In the air of surrounding；High-temperature water, which enters in tank, to be stagnated, and such high-temperature water just distributes heat, forms water at low temperature,
Meanwhile, another is connected with micro pump in tank, and micro pump transmits the water at low temperature in tank to opposite side
Capillary water pipe in, then another water storage to taken the heat of the iron plate of this side and shell by the capillary water pipe of this side
In container, material is thus formed water circulation, the effect of continued down is reached.Because the specific heat capacity of water is very big, its heat absorbed
It is a lot, such heat can make a brief stay in water, is easy to around universal power amplifier original heat to big sky
Between transmitted, be conducive to the radiating of universal power amplifier.
The present invention compared with prior art, has the following advantages and advantages：The present invention utilizes the specific heat capacity of water very
Greatly, its heat absorbed is a lot, and such heat can make a brief stay in water, is easy to around universal power amplifier former
Some heats are transmitted to large space, are conducive to the radiating of universal power amplifier.
