Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of radiator for power amplifier of the invention.
Specific embodiment
Referring to Fig.1, the present invention provides a kind of radiators for power amplifier, for carrying out to power amplifier 6
Heat dissipation, the radiator includes metal shell 1, and the shape of the Internal periphery and power amplifier 6 of the metal shell 1 matches,
It is filled with netted samming heat-conducting medium matrix 2 in the metal shell 1, the netted samming heat-conducting medium matrix 2 is adsorbed with phase
Become material 3.
The Internal periphery of metal shell 1 and the shape of power amplifier 6 match, and in Fig. 1, power amplifier 6 is cylinder,
Metal shell 1 is made of upper and lower two parts, and the Internal periphery of metal shell 1 is made of two semi-cylindricals, in use, by metal
Two parts up and down of shell 1 are buckled on power amplifier 6, so that metal shell 1 matches with power amplifier 6, are realized good
Heat dissipation effect.
In addition, when power amplifier 6 be it is plate when, then the Internal periphery of metal shell 1 be fabricated to it is plate can be with function
Rate amplifier 6 matches.
When power amplifier 6 is using annular shape, the Internal periphery of metal shell 1 is correspondingly arranged as annular shape, and gold
Belonging to shell 1 can consist of two parts, and be easily installed on power amplifier 6, realize Matching installation.
When power amplifier 6 is using square configuration, then it is rectangular that the Internal periphery of metal shell 1 is corresponding.In short, our
In case, the shape of the Internal periphery and power amplifier 6 of metal shell 1 matches, so as to be fitted in and power amplifier 6
On, it radiates to power amplifier 6.
This programme, by being filled with netted samming heat-conducting medium matrix 2 in the metal shell 1 of radiator, and netted
It is adsorbed with phase-change material 3 in the reticulated void of samming heat-conducting medium matrix 2, so as to utilize netted samming heat-conducting medium matrix
2 high thermal conductivity and the highly endothermic performance of phase-change material 3, by the heat rapidly metal from power amplifier 6 through radiator
Shell 1 is transmitted in phase-change material, melts phase-change material, plays good heat-conducting effect, the application suitable for similar vacuum
Environment, and this radiator is suitble to batch automatic production.
It is further used as preferred embodiment, the netted samming heat-conducting medium matrix 2 uses porous graphite, foam copper
Or foamed aluminium.Porous graphite, foam copper or foamed aluminium are the very high spongy materials of voidage, and porosity is 85% or more, stone
Ink, copper or aluminium are thermally conductive good material, and can be used to, which improves phase-change material poor heat conductivity bring non-uniform temperature itself, asks
Topic, and do not influenced by gravity direction.
It is further used as preferred embodiment, the phase-change material 3 uses higher alcohols.
Higher alcohols are a kind of organic phase change materials, and being become in the phase transition process of liquid by solid-state can be absorbed big calorimetric, can
To absorb the heat of the generation of power amplifier 6, guarantee its work in the temperature range of permission.In the present solution, phase-change material 3 is from admittedly
When state becomes liquid, the difference of heat is absorbed according to each position, can be flowed freely in netted samming heat-conducting medium matrix 2, two
Person is implemented in combination with good heat conductive effect.
In addition, higher alcohols are organic composite material series, each temperature section in 20-85 DEG C of temperature range has pair substantially
The material category answered is easy to use.And the usual very little of density of higher alcohols (under liquid, is less than 1g/cm3), packing material
It measures also smaller (less than 15%).
It is further used as preferred embodiment, multiple radiating fins 4 are equipped in the metal shell 1, it is described netted equal
Warm heat-conducting medium matrix 2 is filled between multiple radiating fins 4.
The heat that phase-change material 3 generates can be better transmitted to metal shell 1 by radiating fin 4, so that heat dissipation effect
More preferably.
Metal shell 1 preferably uses aluminum alloy materials, good heat dissipation effect, and density is small, can while guaranteeing heat dissipation effect
To guarantee the lightness of radiator.
It is further used as preferred embodiment, is additionally provided in the metal shell 1 multiple rigid for reinforcing metal shell 1
The reinforcing rib 5 of degree, and the multiple reinforcing rib 5 and multiple radiating fins 4 all have gap, so that 1 inner space of metal shell
For connected space.
Gap is all had between reinforcing rib 5 and radiating fin 4, so that closed independent cavity will not be formed, is avoided to phase
The flowing for becoming phase-change material in the filling and phase transition process of material impacts.
Reinforcing rib 5 and the quantity of radiating fin 4 may be the same or different.According to rigidity requirement and cooling requirements into
Row setting.
Be further used as preferred embodiment, the radiating fin 4 with a thickness of 1~1.5mm, the reinforcing rib 5
Height is 1.4~1.6mm.After setting reinforcing rib 5, the rigidity of metal shell 1 can be increased, reduce phase-change material phase transformation
The deformation of metal shell 1 caused by air pressure inside changes in journey.
It is further used as preferred embodiment, the gap between the multiple reinforcing rib 5 and multiple radiating fins 4 is big
In 1mm.
It is further used as preferred embodiment, the spacing between the radiating fin 4 is 5~10mm.Radiating fin 4 it
Between spacing mainly determine that the working time is longer by the working time of radiator, spacing is bigger, can achieve 10mm, so as to
To fill more phase-change materials, preferably heat dissipation is realized, and the design of more lightness may be implemented.
It is further used as preferred embodiment, the thickness of the metal shell 1 is greater than 1.5mm.In addition, metal shell 1
Upper thickness limit can be set according to the size of power amplifier 6, in general, be less than 10mm.
Generally speaking, this radiator in metal shell 1 by growing radiating fin 4, the fill-net between radiating fin 4
Then shape samming heat-conducting medium matrix 2 fills phase-change material 3 in netted samming heat-conducting medium matrix 2, can absorb heat meeting
The advantages of measuring in the case where requiring, making full use of a variety of materials, reaches integral miniaturization, light-weight design.And this radiator
The heating conduction and heat absorption capacity feature of a variety of materials itself are made full use of, thermally conductive and endothermic effect is not by gravity direction, the external world
Air pressure, the influence reliability of temperature are higher.And this heat spreader structures is simple, processing cost is low, high-efficient, simple process, to life
It is not high to produce operator's technical requirements, product quality consistency is high, can carry out high-volume automated production, guarantees product quality
Consistency.
It is to be illustrated to preferable implementation of the invention, but the invention is not limited to the implementation above
