Description
Technical field
The utility model relates to microwave and puts the large device field of power, microwave power amplifier cooling system specifically.
Background technology
High merit amplifier is because power consumption is large, frequency is high, high to the efficiency requirements of heat radiation.If temperature is too high, integrated circuit is fragile, and causes letter signal to interrupt.Traditional microwave power amplifier radiator adopts wind-cooling heat dissipating usually, mainly fan and copper, aluminium radiating fin is combined and dispels the heat.But heat is in the transmission of in-plane, copper and aluminothermy hinder all too large, make heat be delivered to far-end and require great effort very much, make radiating fin utilance not high, radiating efficiency is low, not only have impact on the stability of power amplifier, and decreases power amplifier useful life.
Utility model content
Not enough for above-mentioned prior art, the utility model provides a kind of microwave power amplifier cooling system.
The microwave power amplifier cooling system that the utility model provides is achieved through the following technical solutions:
A kind of microwave power amplifier cooling system, comprise microwave power amplifier, phase-change heat sink, radiating fin, temperature sensor, radiator fan, controller, it is characterized in that: bottom phase-change heat sink, be close to microwave power amplifier, radiating fin is close at phase-change heat sink top, microwave power amplifier is built with temperature sensor, temperature sensor is connected with controller by optical fiber, arranges radiator fan in radiating fin, and radiator fan is electrically connected with controller.
Described temperature sensor is fiber-optical grating temperature sensor.
The beneficial effects of the utility model are:
1, adopt phase-change heat mode to dispel the heat to microwave power amplifier, good heat dissipation effect, temperature is relatively stable, for the stable operation of power amplifier provides safeguard;
2, monitor in real time temperature, thus control the rotating speed of radiator fan, power saving more, decreases the loss of fan.
3, adopt fiber-optical grating temperature sensor, fiber-optical grating temperature sensor itself is without the need to power supply, more energy-conservation, and fiber-optical grating temperature sensor long service life.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Microwave power amplifier cooling system as shown in Figure 1, comprise microwave power amplifier, phase-change heat sink, radiating fin, temperature sensor, radiator fan, controller, microwave power amplifier is close to bottom described phase-change heat sink, radiating fin is close at phase-change heat sink top, microwave power amplifier is built with temperature sensor, temperature sensor is connected with controller by optical fiber, arranges radiator fan in radiating fin, and radiator fan is electrically connected with controller.
Further, described temperature sensor is fiber-optical grating temperature sensor.
During microwave power amplifier work, the heat that microwave power amplifier produces is passed to radiating fin by phase-change heat sink, and radiating fin coordinates with radiator fan heat is drained into the external world.Temperature sensor is responded in real time to microwave power amplifier temperature, and light signal is passed to controller, controller by the process of signal and analysis, and controls the rotating speed of radiator fan, microwave power amplifier temperature height then strengthens rotating speed, and microwave power amplifier temperature is low, reduces rotating speed.
