Abstract
The utility model discloses a heat pipe radiator based on a static VAR generator. The radiator is characterized by comprising a heat radiation plate (1), a plurality of heat radiation pipes (2) and heat radiation fins (3), wherein the heat radiation pipes (2) are sealed at two ends and filled by heat transfer medium. The heat radiation plate (1) is fixedly connected with IGBTs (5) of the static VAR generator. A plurality of plugging holes (4) are uniformly distributed in the heat radiation plate (1), and one end of each heat radiation pipe is correspondingly plugged into the plugging hole (4) of the heat radiation plate (1), forming expanding joint. The heat radiation fins (3) are arranged in multiple rows and in expanding joint with the heat radiation pipes (2) at positions close to the other ends of the heat radiation pipes (2). The radiator provided by the utility model has the advantages of small size and high heat radiation capacity, and improves the current utilization rate of the IGBTs, thereby increasing the output capacity of the SVG (static VAR generator) mounted in a standard GGD cabinet.
Description
Technical field
The utility model relates to radiator, specifically at industrial electrical network quality controlling and reactive power compensation and the static reacance generator radiator that designs.
Background technology
There is following problem mostly in the designed static reacance generator (SVG) of present each producer:
Taking full advantage of because of temperature problem 1: adopt aluminium radiator to carry out forced air cooling, and existing aluminium radiator heat-sinking capability is limited, makes the IGBT(insulated gate bipolar transistor) is restricted.
2: owing to will allow IGBT move big electric current, must adopt the aluminium radiator of large volume, thereby cause its shared spatial volume very big, be unfavorable for the installation of other components and parts in the installation of SVG of two power cells and the SVG cabinet.
The utility model content
For fear of the weak point that prior art exists, the utility model provides a kind of and has the fabulous heat-pipe radiator of radiating effect, thereby improves the current utilization rate of IGBT greatly.
The utility model technical solution problem adopts following scheme:
Heat-pipe radiator based on static reacance generator is characterized in that, radiator comprises the radiating tube that heat transferring medium is housed and the radiating fin of heating panel, many closed at both ends; The IGBT of the fixedly connected static reacance generator of described heating panel is evenly equipped with a plurality of spliced eyes in the heating panel, described every radiating tube one end correspondence is plugged in the spliced eye of heating panel and forms expanded joint; Radiating tube has many row's radiating fins near the even expanded joint of the other end.
The utility model design feature also is:
Described radiating tube is vacuum tube, and the heat transferring medium in the heat exchanger tube is water.
Described heat exchanger tube is copper material, and described heating panel is aluminium, and heating panel is connected residing outer surface with IGBT be copper base outer surface.
The heat radiation pipeline section that is positioned at spliced eye top, radiating fin below is made as bending section.
Compared with the prior art, the utility model advantage applies exists:
1: the utility model heat-pipe radiator, heat-sinking capability are very strong, have improved the current utilization rate of IGBT, thereby have improved the output capacity of the SVG that adopts the installation of standard GGD cabinet.
2: in the utility model because the reducing of radiator volume, thereby reduced the installation difficulty of two power cell SVG, also improved the simple installation of other components and parts.
Description of drawings
Fig. 1 is the utility model heat-pipe radiator structure schematic diagram.
Number in the figure: 1 heating panel, 2 radiating tubes, 21 bending sections, 3 radiating fins, 4 spliced eyes, 5 IGBT.
Technical solutions of the utility model are done further by embodiment below in conjunction with accompanying drawing and to be explained.
Embodiment
As shown in Figure 1, radiator comprises the radiating tube that heat transferring medium is housed 2 and the radiating fin 3 of heating panel 1, many closed at both ends; The IGBT 5 of heating panel 1 fixedly connected static reacance generator is evenly equipped with a plurality of spliced eyes 4 in the heating panel 1, the height of the degree of depth of spliced eye and heating panel 1 is suitable, and every radiating tube one end correspondence is plugged in the spliced eye 4 of heating panel and forms expanded joint; Near the even expanded joint of the other end many row's radiating fins 3 are arranged.
If adopting water is heat transferring medium, radiating tube 2 adopts vacuum tube, to guarantee WATER AS FLOW MEDIUM energy explosive evaporation when reaching 40-50 degree centigrade, realizes heat exchange.
Heat exchanger tube adopts copper material during concrete enforcement, and heating panel adopts aluminium, and heating panel is connected residing outer surface with IGBT be that (the copper base refers to copper to be the alloy that major ingredient forms to copper base outer surface, powdered metallurgical material.Having the performance of a series of excellences such as high-strength, electric-conductivity heat-conductivity high, high corrosion resistant, biocidal property, platability, ornamental, workability, is existing well known materials).Move as SVG under the situation of big electric current, thereby IGBT can produce a large amount of heats causes copper primary surface temperature to rise, heat conducts to radiating tube, the evaporation that comes to life of aqueous medium in the radiating tube, water vapour up flows through radiating tube and radiating fin heat radiation condensation, the water of condensation is back to radiating tube bottom, heat radiation and so forth by inside pipe wall.For the condensed water that delays not cool off fully at the radiating tube top is back to the radiating tube bottom along inwall rapidly, be positioned at above the spliced eye, heat radiation pipeline section below the radiating fin is provided with all or part of bending section 21, thereby increase the condensate return stroke, make the condensed water and the radiating tube inwall that do not cool off fully carry out sufficient heat exchange, and by radiating tube heat is transferred out.
