Description
Technical field
The utility model relates to a kind of urban rail car traction power supply rectifier, refers in particular to the heavy duty rectifier that adopts heat-pipe radiator, belongs to DC power-supply system rectifying device class.
Background technology
The poly phase rectification device that the power supply of city railway rectifier is made up of 12 pulse waves or 24 pulse waves generally all adopts air natural cooling mode.Because this mains unit horsepower output is big, requires the overload capacity height, the colleague all uses general aluminium section bar radiator both at home and abroad, helps the heater members heat radiation in the rectifier.But owing to be subjected to the limitation of aluminium section bar this body structure of radiator and the material used, cause its heat-sinking capability little, therefore just must adopt a plurality of semiconductor elements parallel connections to use, it is poor to form the current balance degree that occurs the brachium pontis parallel branch in actual use, many defectives such as the element degree of utilization is low, and the screen cabinet is long-pending big; So also make subway substation building area big, have to make whole construction investment to increase.
Therefore, how to change this structure of passing through usefulness, provide that a kind of volume is little, the urban rail car traction power supply rectifier of good heat dissipation effect, become a kind of expectation of the research and development production unit and the department of use.
The utility model content
The purpose of this utility model: the novel urban rail car traction power supply rectifying device that is intended to propose a kind of heat pipe-type radiator structure, can effectively overcome many defectives of aluminium section bar heat spreader structures, both improved its structure, improved in-use performance, and can allow it reduce volume again simultaneously and reach miniaturization.
This urban rail car traction power supply rectifying device, it mainly is a principle of utilizing heat pipe heat radiation, the power semiconductor and the heat-pipe radiator that produce heat energy are combined into one, allow the interior liquid heat-transfer medium of heat pipe transform by liquid heat absorption vaporization, the liquid-vapour-liquid that returns liquefaction again of catching a cold, in this course heat is distributed, finally reach the desirable radiating effect of rectifying device.
This urban rail car traction rectifier device cabinet, be made up of screen cabinet housing 8, rectistack 1, DC master row 5, interchange busbar 6 and supporter etc., it is characterized in that: described rectistack 1 is fitted in a plurality of power semiconductors 7, block heat-pipe radiator 2 the right and left that is embedded with flange-cooled heat pipe-type bar shaped radiator 3 by assembly parts 4; And described power semiconductor 7 and the block radiator form of being arranged alternately press-fit.
The heat pipe 10 that is embedded with many band radiating gills 11 all is set on described block radiator 2 and the bar shaped radiator 3.
Described heat pipe 10 becomes 12 ° of angles with horizontal surface.
According to this urban rail car traction power supply of above technical scheme design-calculated rectifier, to compare with the simple aluminium section bar structure radiator that generally uses at present, its advantage is, both reduced semiconductor devices 50%, simplify the rectistack structure, and can reduce the rectifier volume, make easy row easy to maintenance; Also improve simultaneously radiating effect greatly.

Accompanying drawing 2 is a rectistack constructional drawing;
Accompanying drawing 3 is the lateral plan of accompanying drawing 2;
Accompanying drawing 4 is heat pipe principle of work and heat pipe mounting inclination angle degree scheme drawing.
Among the figure: 1, rectistack 2, block radiator 3, bar shaped radiator 4, assembly parts 5, DC master row 6, exchange busbar 7, semiconductor devices 8, screen cabinet housing 9, press-fit part 10, heat pipe 11, radiating gill.
The specific embodiment
This urban rail car traction power supply rectifier shown in Fig. 1-4 is compared with the aluminium section bar heat dissipation type mains unit of the same type that generally uses at present, and its technical innovation is mainly reflected in following three aspects:
One, the urban rail car traction power supply rectifier that the utility model proposes adopt the heat pipe-type radiator structure, do like this and can effectively reduce brachium pontis semiconductor element number in parallel and annex number thereof;
Two, the present utility model is made up of 6 rectistacks, each rectistack is made up of block heat-pipe radiator and strip heat-pipe radiator, and power semiconductor alternately press-fited about on the strip heat-pipe radiator by block heat-pipe radiator form, make the vertical direction radiator number of plies reduce half, under the natural air cooling condition, can reduce the ambient temperature of upper strata semiconductor element.
Three, in the present utility model in advance with heat pipe by become 12 ° of angles to insert matrixes with horizontal surface, heat-pipe radiator can level be installed;
The urban rail car traction power supply rectifier of this employing heat-pipe type radiator, its radiating principle is as shown in accompanying drawing 4: be in the interior liquid heat-transfer medium of heat pipe after the heat pipe bottom is heated, the medium vaporization is risen heat and is taken the finned heatsink on heat pipe top to hot vapour; When the radiating gill heat of being with that disperses, the vaporization medium becomes again behind the drop along 12 ° the tube wall by gravity of tilting and turns back to the pipe bottom that is heated, and circulating repeatedly with this reaches radiating effect.
From accompanying drawing 1 to accompanying drawing the utility model structural representation of 3, concrete structure of the present utility model as can be seen.
This urban rail car traction power supply rectifier, be a kind of 12 pulse wave rectifier devices, in screen cabinet housing 8 by rectistack 1, block radiator 2, strip radiator 3, directly, exchange busbar 5,6 and assembly parts is formed the main body framework, wherein the rectistack of being made up of heat-pipe type radiator 1 is alternately press-fited at the right and left of bar shaped radiator 3 by power semiconductor 7 usefulness assembly parties 4 and block radiator 2 and forms; Be embedded with finned heatsink on the heat pipe 10 that is provided with on block radiator 2 and the bar shaped radiator 3, reflux for guaranteeing the heat-conduction medium after the vaporization, these heat pipes should be obliquely installed, and itself and horizontal plane angle should be not less than 12 °.
