Description
Technical field
The utility model relates to a kind of radiator, particularly relates to the special phase-change heat sink of a kind of microwave power amplifier.
Background technology
Power amplifier is the important component part of microwave equipment, if amplifier breaks down, circuit single channel will be caused to block, affect the reliability of microwave communication.High merit amplifier is because power consumption is large, frequency is high, high to the efficiency requirements of heat radiation.Microwave circuit fault also normally because temperature is too high, is damaged integrated circuit, and is caused letter signal to interrupt.Traditional amplifier radiator adopts wind-cooling heat dissipating usually, mainly fan and copper, aluminium radiating fin are combined, adopt the heat radiation of heat transfer form, 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, have impact on the stability of power amplifier.And fan itself also can consume energy, fan is also not suitable for long work.
Utility model content
Not enough for above-mentioned prior art, the utility model provides a kind of energy-conservation, low noise, the special phase-change heat sink that radiating efficiency is high.
The special phase-change heat sink of a kind of microwave power amplifier that the utility model provides is achieved through the following technical solutions:
The special phase-change heat sink of a kind of microwave power amplifier, comprise housing, radiating fin, end cap, described radiating fin to be arranged on housing and to be close to housing upper surface bottom radiating fin, housing and end cap form vacuum chamber jointly, phase-change material is had in vacuum chamber, it is protruding that housing bottom arranges multiple positive tetrapyamid shape, and housing bottom both sides arrange L-type bearing.
Described vacuum chamber upper wall arranges many triangle raised lines.
Heat-conducting silicone grease is scribbled bottom described radiating fin and between housing upper surface.
The beneficial effects of the utility model are:
1, housing bottom arranges multiple positive tetrapyamid shape projection, and heat-conducting area is increased, and housing bottom heat conduction efficiency significantly improves;
2, vacuum chamber upper wall arranges many triangle raised lines, and gaseous working medium and vacuum chamber upper wall contact-making surface are increased, and triangle raised line is conducive to the backflow of condensed liquid refrigerant;
3, adopt accurate encapsulation, vacuum degree is high, and uniform temperature is improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 makes the utility model structure cutaway view.
Mark in figure: housing 1, projection 11, radiating fin 2, end cap 3, bearing 4, raised line 5.
Embodiment
The special phase-change heat sink of a kind of microwave power amplifier as depicted in figs. 1 and 2, comprise housing 1, radiating fin 2, end cap 3, described radiating fin 2 to be arranged on housing 1 and to be close to housing 1 upper surface bottom radiating fin 2, housing 1 and end cap 3 form vacuum chamber jointly, phase-change material is had in vacuum chamber, arrange multiple positive tetrapyamid shape projection 11 bottom housing 1, housing bottom both sides arrange L-type bearing 4.
Further, described vacuum chamber upper wall arranges many triangle raised lines 5.
Further, heat-conducting silicone grease is scribbled bottom described radiating fin 2 and between housing 1 upper surface.
The utility model is when using, be arranged on microwave power amplifier by L-type bearing 4, the heat that amplifier produces is passed to bottom vacuum chamber by multiple positive tetrapyamid shape projection 11, phase-change working substance bottom vacuum chamber, by thermal evaporation, is evaporated to vacuum chamber top and heat is passed to radiating fin 2, and phase-change working substance meets cold rear condensation, reflux along triangle raised line 5, bottom vacuum chamber, absorb heat again, reciprocation cycle, complete the heat radiation of microwave power amplifier.
