Materialogy angle is set out, and a kind of certainly cooling alloy material and processing technology for high voltage power supply heat transmission is provided.Suitable
Heat dissipation design and operating condition under, the material can overcome presently, there are heat dissipation problem, and considerably increase high voltage power supply
Safety in the process of running.
Summary of the invention
The purpose of the present invention is to overcome the deficiency in the prior art, provide under a kind of high voltage power supply 120-180 degree with aluminium base from
Coolant and technique.The material is divided into two-phase since spinodal decomposition has occurred: not undergoing phase transition within the scope of exothermic temperature
High-melting-point phase and the low melting point phase that can be melted in operating temperature range.The material is at the working temperature when there is big hot-fluid to generate
When can occur part melt, so as to absorb the generation (self cooled mechanism) of heat rapidly.Meanwhile material formation
Liquid phase can generate free convection due to concentration difference in infusible skeleton, and the movement of this fluid can further increase scattered
The thermal efficiency.
To achieve the goals above, the present invention adopts the following technical scheme:
With aluminium base from coolant and technique under a kind of high voltage power supply 120-180 degree.By weight percentage, the composition of alloy
Are as follows: Ti:0.4-1.0wt.%, Cu:2.0-3.0wt.%, Mn:0.5-0.8wt.%, Co:1.0-2.0wt.%, Sb:15.0-
20.0wt.%, B:0.1-0.3wt.%, In:20.0-24.0wt.%, Sn:10.0-15.0wt.%, surplus Al.
With aluminium base from the preparation and application of coolant under a kind of above-mentioned high voltage power supply 120-180 degree, including it is as follows
The step of :(a) ingredient: raw material weighing is carried out according to ingredient as above；(b) smelt: the antivacuum induction using argon gas protection is molten
Furnace carries out melting, and wherein crucible uses graphite crucible；10 minutes are kept the temperature in 700-750 degree and are melted alloy using electromagnetic agitation
Body is sufficiently stirred, and then carries out swage tool and is cast, and be rapidly cooled the extruding of (c) room temperature using water cooling: carrying out room temperature

Point phase).Within the scope of high voltage power supply normal working temperature, high-melting-point will not mutually occur fusing and in a disguised form in the material as non-phase
As skeleton (volume content is in 70-75%).Meanwhile low melting point is mutually solid phase under the normal working temperature of high voltage power supply, still
It can rapidly be melted under conditions of generating big hot-fluid due to short circuit etc. and generate liquid metal.The liquid of these low melting points
State metal, can also be in the bone of high-melting-point phase other than largely absorbing heat when fusing (fusion enthalpy required for phase transformation)
It is carried out in frame efficient thermally conductive.High-efficiency heat conduction is other than liquid metal can carry out void-free contact heat transfer with solid skeleton, also
It can be formed since the free convection bring that temperature gradient causes density different and generates further radiates.These mechanism are comprehensive
