Embodiment
Below according to accompanying drawing and specific embodiment of the invention, the present invention will be described in detail.
As illustrated, a kind of big current-carrying capacity insulation pouring bus of the present invention, using medium in heat pipe close to vacuum
Evaporation cooling phenomenon in shell obtains higher thermal conductivity factor, improves insulation pouring bus because of internal bus radiating condition.
Specifically, in insulation pouring bus, centered on bus 3, insulating heat-conductive ceramic layer 2, heat are outwards set gradually
Tube layer 4.Insulating heat-conductive ceramic layer shown in figure and heat pipe layer 4 are symmetrical arranged in busbar both sides, and its heat dispersion is only to exist
Bus side sets 2 times when insulating heat-conductive ceramic layer 2, heat pipe layer 4.As illustrated, the heat pipe layer includes some settings
Heat pipe on the outside of insulating heat-conductive ceramic layer, it is condensation end also settable radiating fin in outside in the outer end of the heat pipe.It is actual
In engineering insulating heat-conductive ceramic layer 2 and heat pipe layer 4 be only respectively provided with the one or both sides of bus 3 can according to busbar carrying capacity dissipate
Heat demand determines.
Between bus and the insulating heat-conductive ceramic material in intermediate layer, between the evaporation side of each heat pipe and insulating heat-conductive ceramic material
It is brought into close contact using stickiness heat-conducting glue 5, it is outside that condensation is placed on closing.The size and thickness, each heat pipe of insulating heat-conductive ceramics
Shell size, shape and quantity can combine bus current-carrying capacity and technological design depending on.
It is to discharge bus with insulating heat-conductive ceramic material and ceramic material with pouring material using the purpose of heat-conducting glue 5
The air plankton emptying being bonded at section, to reduce heat transfer resistance.Certain higher compacting manufacturing process is such as used, can be realized
When will make to connect in a manner of thermal resistance is minimum between each heat-conducting section, use can be also omitted.
Consider that shell be metal material in heat pipe, as it is directly contacted with bus, preventing for insulation pouring bus may be reduced
The performance such as water, dust-proof.Therefore insulating heat-conductive ceramics are set between bus and heat pipe, do not destroyed while bus radiating condition is improved
The performance of insulation pouring bus.The selection of ceramic material can consider various insulating heat-conductive ceramics.
Heat pipe used uses the higher copper shell through preservative treatment of thermal conductivity factor, and one compacting forms, avoids welding
Or solder joint is reduced to reduce the influence to heat transfer resistance.Heat pipe heat radiation fin is using the higher material of thermal conductivity factor, such as using gold
Then each fin outer surface need to carry out preservative treatment to be adapted to the requirement of the anti-corrosion and waterproof of field of employment to category fin.
Bus heat dissipation capacity is calculated according to busbar carrying capacity, it is determined that being radiated using heat pipe or heat-pipe radiator.Bus carries
When flow is smaller, radiating is less, only can set some heat pipe insertion insulation pouring buses along insulation pouring bus length direction
Inside radiated, bus and insulating heat-conductive ceramics, ceramics and heat pipe evaporation side are by heat conduction glue laminating, to exclude joint place
Air plankton, heat pipe or heat-pipe radiator is set to be connected with bus in a manner of thermal resistance is minimum；Busbar carrying capacity can be exhausted when larger
Radiator separately is set on the outside of edge cast bus, i.e., reinforcing radiating is carried out using heat-pipe radiator.Heat pipe or heat-pipe radiator size and
Shape need to be combined depending on the current-carrying capacity of bus.
According to a preferred embodiment of the invention, carried out using a kind of big current-carrying capacity insulation pouring bus heat dissipating method exhausted
When edge pours into a mould bus technological design, it is proposed that heat pipe or heat-pipe radiator and the integrated design of insulation pouring bus, manufacture.
Present disclosure is discussed in detail by above preferred embodiment, but it should be appreciated that the description above
It is not considered as limitation of the present invention.After those skilled in the art have read the above, for a variety of of the present invention
Modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
