Description
Technical field:
The present invention relates to the transformer technology field, refer in particular to a kind of dry-type phase-transition comprehensive radiator that is used for high-low voltage electric power distribution cabinet.
Background technology:
As everyone knows, one of core technology of high-low voltage electric power distribution cabinet is exactly that power distribution cabinet is when operation; Because the generation of electric heating; Cause the high-low voltage electric power distribution cabinet internal temperature to raise and be called for short temperature rise, the excessive serviceability that has a strong impact on power distribution cabinet of temperature rise, even produce the electric short circuit accident; Reducing the high-low voltage electric power distribution cabinet in-cabinet temperature, also is the common technical goal of pursuing of distribution industry.Past industry standard practice is: on the power distribution cabinet door-plate, opens ventilation hole, welds gauze then, and through this form cooling, the first, cooling-down effect is not obvious, and natural heat dissipation lacks concurrent condition; The second, because opened ventilation hole, degree of protection does not reach national standard; The 3rd, can not satisfy the filthy environment of severe and use.The blower fan forced heat radiation is being installed additional on the door-plate or on the cabinet top in some factory in the industry, and at first blower fan must be own high temperature resistant, need connect power supply again; And installing must be firmly; Because above-mentioned three conditions often cause the forfeiture of high-low voltage electric power distribution cabinet heat sinking function, even reach the heat radiation purpose; Also can not reach the degree of protection of high-low voltage electric power distribution cabinet, because toy entering fan jumps and causes that the thing of short circuit accident often has generation.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art; Provide a kind of radiating block need not consume energy, can circulate and use repeatedly, solved the contradiction of power distribution cabinet heat radiation with degree of protection; Improve the heat sinking function of power distribution cabinet greatly; Reduce temperature rise, improved and stablized the serviceability of high-low voltage electric power distribution cabinet, have and safeguard use value widely.
For realizing above-mentioned purpose; Technical scheme provided by the invention is: a kind of dry-type phase-transition comprehensive radiator that is used for high-low voltage electric power distribution cabinet; Include the radiator mainboard of making by aluminium or aluminium alloy, it is characterized in that: on radiator mainboard, excavate out cavity volume, add a plurality of copper heat radiation short tubes that cave in the bottom of cavity volume; Be filled with phase-change material in the cavity volume, be furnished with the cavity volume cover plate on the cavity volume; Excavation has a plurality of mainboard grooves on radiator mainboard, and as gas channel, this mainboard groove is positioned at a side of cavity volume; And communicate with cavity volume through link slot; Externally heat radiation of punching is furnished with cover plate on this groove on the mainboard groove, and this cover plate inboard is provided with the cover plate groove corresponding with the mainboard groove; The gas channel of mainboard groove and cover plate groove forms and intersects, and also is being equipped with external louvre on the cover plate groove and is opening with the hole dislocation on the mainboard groove.
The present invention has fundamentally solved the heat dissipation problem of high-low voltage electric power distribution cabinet, without any need for additional facilities, and the reusable characteristics of not consuming any energy source, and ability, useful life can be to 30 years.Changing phase-change material in case of necessity gets final product.

Embodiment:
See Fig. 1-shown in Figure 2, include the radiator mainboard of being made by aluminium or aluminium alloy, aluminium alloy thermal resistance small capital body just has suitable heat sinking function; On radiator mainboard, excavate out cavity volume 1, design considers that cavity volume is thicker, and the heat radiation thermal resistance increases; Add a plurality of copper heat radiation short tubes 2 that cave in the bottom of cavity volume 1, increased area of dissipation, the heat conduction of copper heat radiation short tube is better than aluminium simultaneously; Be filled with phase-change material in the cavity volume 1, be furnished with cavity volume cover plate 3 on the cavity volume 1, in case phase-change material leaks; Excavation has a plurality of mainboard groove 4 as gas channel on radiator mainboard; This mainboard groove 4 is positioned at a side of cavity volume 1; And communicate with cavity volume 1 through link slot 5, externally heat radiation of punching is furnished with cover plate 6 on this mainboard groove 4 on mainboard groove 4; These cover plate 6 inboards are provided with the cover plate groove 7 corresponding with mainboard groove 4; The gas channel of mainboard groove 4 and cover plate groove 7 forms and intersects, and also is being equipped with external louvre on the cover plate groove 7 and is opening with the hole dislocation on the mainboard groove, has avoided because heat radiation has reduced degree of protection.Described phase-change material is that graphite powder, volcano stone flour and fusing point are the mixed of 40 ℃～45 ℃ of paraffin.
When the power distribution cabinet temperature rise was comparatively rapid, when having surpassed 40 ℃～45 ℃ work, phase-change material absorbs great amount of heat made phase-change material become liquid from solid; The phase-change material storage area forms thermal high, because the phase-change material cavity volume communicates with the mainboard groove, has just formed enforceable heat dissipation channel and has dispelled the heat again; And heat dissipation capacity is very big, according to the temperature rise needs, can process the radiator of different big or small cavity volumes; Phase-change material adopts paraffin, graphite, pelelith, and its action principle is: utilize 40 ℃～45 ℃ of the transformation temperatures of paraffin to absorb hot gas, utilize graphite to absorb free electron; Because graphite and heat conduction are good, and the expanded by heating coefficient is less, can not burst cavity volume; Pelelith is the material of a kind of high temperature resistant and porous, light weight; Itself be that goodish respiratory function is arranged, heat overstocks when adopting pelelith to reduce phase transformation, the structure after loose its fusing.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
