Whole chip is just diffused into, one can consider that whole chip is substantially isothermal.The radiator structure used at present will be welded
Or other modes are contacted with power amplifier, heat is from power amplifier transfer to radiator structure.
As patent CN205754220U discloses a kind of power amplifier cooling device, including shell body, power amplifier
Circuit board and coldplate, described shell body lower end are provided with supporting leg, and described power amplifier circuit plate upper and lower end is equipped with
Coldplate, lower coldplate is fixed on shell body, and upper coldplate is sticked on lower coldplate, described power amplifier circuit plate
Centre is provided with moving blade provided with a pair of motors, motor；Upper and lower coldplate one end extends to shell body outer end,
It is described extend to connect in shell body outer end portion connect cooler on circulating pump, circulating pump.The utility model is put in power
The circuit board upper and lower end that big device mainly produces heat sets coldplate, while heat conduction efficiency is improved using wind-force auxiliary heat dissipation,
Improve radiating effect.
But, deformation is constantly inevitably resulted from welding or other modes contact in the template containing bottom plate,
And because bottom plate is merely able to be fixed on radiator by screw in surrounding, the incomplete contact between of template and spreader surface
The incomplete of radiating can be caused, the transmission of heat is influenceed, cause subregion high temperature on power amplifier and influence power amplification
The use of device.
The content of the invention

In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1st, radiator of the present utility model point two parts, hot channel is wrapped in microwave power amplifier in spiral form
Heat is absorbed around body, and the medium channel connected with hot channel is located in fin, quickly heat is dissipated by fin
Lose, the compression pump that hot channel is provided with can promote heat continually with the medium in circulation cooling pipeline and medium channel
Transmitted at microwave power amplifier to fin, and heat is constantly scattered and disappeared, and medium is constantly circulated, and realizes heat
It is uniform to scatter and disappear, it is ensured that the normal work of instrument, it is to avoid due to being radiated caused by contact with power amplifier not exclusively endless
Full the problem of.
2nd, fin of the present utility model is connected in " S " type mode, it is ensured that medium and fin in medium channel
Maximum Contact, can quick dissipated heat, the medium temperature in reduction medium channel.
3rd, air or water are filled with medium channel of the present utility model and hot channel, by air-cooled or water cooling
Mode radiates, as long as the temperature of the air or water in hot channel is less than the temperature of microwave power amplifier, it is possible to by heat
Amount is endlessly taken away, and cost is low and good heat dissipation effect.
