Fig. 1 is a kind of structure diagram of radiator for power amplifier of the present invention.
Specific embodiment
With reference to Fig. 1, the present invention provides a kind of radiator for power amplifier, for being carried out to power amplifier 6
Heat dissipation, the radiator include metal shell 1, and the shape of the Internal periphery and power amplifier 6 of the metal shell 1 matches,
In the metal shell 1 phase is adsorbed with filled with netted samming heat-conducting medium matrix 2, the netted samming heat-conducting medium matrix 2
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 housing 1 are buckled on power amplifier 6, so as to which metal shell 1 matches with power amplifier 6, are realized good
Heat dissipation effect.
In addition, when power amplifier 6 for it is plate when, then the Internal periphery of metal shell 1 be fabricated to it is plate can be with work(
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 housing 1 can be made of two parts, 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.It is 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
Phase-change material 3 is adsorbed 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 heat rapidly from metal of the power amplifier 6 through radiator
Housing 1 is transmitted in phase-change material, melts phase-change material, plays good heat-conducting effect, suitable for the application of similar vacuum
Environment, and this radiator is suitble to batch automatic production.
Preferred embodiment is further used as, the netted samming heat-conducting medium matrix 2 is using 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 more than 85%, stone
Ink, copper or aluminium are the good material of heat conduction, and can be used for, which improves the non-uniform temperature that phase-change material poor heat conductivity itself is brought, asks
Topic, and do not influenced by gravity direction.
Preferred embodiment is further used as, the phase-change material 3 uses higher alcohols.
