Description
Technical field
The utility model relates to a kind of heat sink, particularly high voltage converter room heat sink.
Background technology
The indoor environment temperature that high voltage converter normally works should be 0 ~ 40 DEG C.And the caloric value of high voltage converter is very large, the energy of heating loss is generally 2% ~ 4% of its rated power, and this just needs heat to drain into outdoor, makes indoor temperature be less than 40 DEG C, ensures the normal operation of frequency converter.The normal work of frequency conversion system, not only can make the energy-saving run such as oil transfer pump, water injecting pump, also can reduce mechanical shock, the wearing and tearing of pump assembly, valve, motor etc. simultaneously, extend their maintenance cycle and service life, ensure that oil gas field is produced and steadily, in an orderly manner run.
The existing several type of cooling of frequency converter comprises: the open cooling in air channel; The airtight cooling of air-conditioning; Sky-watertight cooling; The combination of apparatus body water cooling and above-mentioned several type of cooling.
The pluses and minuses of this several type of cooling are: the open type of cooling-initial outlay in air channel is few, run simple, but cooling-down effect depend on local environment temperature; The airtight type of cooling of air-conditioning-required refrigerating capacity is large, and electric power consumption is high; Sky-watertight cooling and apparatus body water cooling-cooling-down effect significantly, but lack security, once cooling water pipeline breaks, leak and will jeopardize the safe operation of high voltage converter.
In the cooling system that existing " mechanical exhaust is freezed with cabinet air-conditioner " combines, Transducer Room exterior wall top installation shaft flow fan, to get rid of the heat of whole Transducer Room; Aluminum alloy beancurd leaf air port is installed in Transducer Room exterior wall bottom, in order to indoor benefit wind; Meanwhile, indoor location cabinet air conditioner, opens when Transducer Room heat is larger, lowers the temperature to whole frequency converter indoor temperature.
The cooling system that this " mechanical exhaust is freezed with cabinet air-conditioner " combines, the heat of generation is directly drained into indoor by frequency converter, defines in " mixing circulation district " with indoor cold wind.In relatively airtight Transducer Room, the hot-air that frequency converter is discharged can not all be carried out cooling process by air-conditioner, and the cold air of frequency converter suction neither cold wind completely after air-conditioning temperature-reducing, has therefore occurred that cooling effectiveness is low, the problem that energy consumption is high.
Utility model content
The purpose of this utility model is to provide the high voltage converter room heat sink that a kind of cooling effectiveness is high, energy consumption is low.Frequency conversion equipment ambient temperature is maintained 10 ~ 35 DEG C, frequency conversion room indoor temperature is made to be terraced distribution.
The purpose of this utility model is achieved in that high voltage converter room heat sink, comprise the high voltage converter in building enclosure body, radiator is arranged at high voltage converter top, it is characterized in that: be fixed with ventilator cowling at building enclosure body top, there is an opening cover ventilator cowling lower end, and opening cover upper end is vent passages, and vent passages top has one for the ceiling of rainwater leakage prevention, there is exhaust blower ceiling lower end, and exhaust blower is positioned at outside building enclosure body top layer; The diameter of opening cover is greater than high voltage converter external diameter; Hot-air channel is formed outside high voltage converter and between opening cover.
There is natural flow wind passage described building enclosure body lower end; Natural flow wind passage is positioned at hot-air channel lower end, and natural flow wind passage and hot-air channel form the wind passage that flows.
Described radiator center line overlaps with vent passages center line.
The utility model has the advantages that: because the utility model adopts staged Duct design, natural flow wind passage is bottom, hot-air channel is in centre, vent passages is topmost, vent passages top produces negative pressure by exhaust blower, and by the natural flow shape mixing wind of negative pressure, hot blast and natural wind, the heat that frequency converter radiator is produced is discharged rapidly, this ventilating system adopts natural air inlet, mechanical exhaust mode, can reach the optimum efficiency of cooling.In addition rainwater leakage prevention measure is considered.
Accompanying drawing explanation
Below in conjunction with embodiment accompanying drawing, the utility model is described in further detail:
Fig. 1 is example structure principle of the present utility model.
In figure, 1, building enclosure body; 2, high voltage converter; 3, ventilator cowling; 4, natural flow wind passage; 5, hot-air channel; 6, vent passages; 7, radiator; 8, exhaust blower; 9, ceiling; 10, opening cover.
Detailed description of the invention
As shown in Figure 1, the purpose of this utility model is achieved in that high voltage converter room heat sink, comprise the high voltage converter 2 in building enclosure body 1, radiator 7 is arranged at high voltage converter 2 top, it is characterized in that: be fixed with ventilator cowling 3 at building enclosure body 1 top, and there is an opening cover 10 ventilator cowling 3 lower end, opening cover 10 upper end is vent passages 6, vent passages 6 top has one for the ceiling 9 of rainwater leakage prevention, and there is exhaust blower 8 ceiling 9 lower end, and exhaust blower 8 is positioned at outside building enclosure body 1 top layer; The diameter of opening cover 10 is greater than high voltage converter 2 external diameter; Hot-air channel 5 is formed outside high voltage converter 2 and between opening cover 10.
There is natural flow wind passage 4 described building enclosure body 1 lower end; Natural flow wind passage 4 is positioned at hot-air channel 5 lower end, and natural flow wind passage 4 and hot-air channel 5 form the wind passage that flows, and radiator 7 is frequency converter radiator.
Described radiator 7 center line overlaps with vent passages 6 center line.
Operation principle of the present utility model is: when exhaust blower 8 works, the negative pressure that exhaust blower 8 is formed, the heat that frequency converter radiator produces is sent outside building enclosure body 1 by vent passages 6, ventilator cowling 3 is semi-packing type structure, ventilator cowling 3 and frequency converter radiator surrounding leave certain space and form hot-air channel 5, under hot pressing and swabbing action, natural flow wind passage 4 forms vent passages 6 mixing wind after being lowered the temperature to hot-air channel 5 by outdoor natural wind is discharged outside building enclosure body 1, makes frequency converter ambient temperature maintain 10 ~ 35 DEG C.
Because the utility model adopts staged Duct design, natural flow wind passage 4 is bottom, hot-air channel 5 is in centre, vent passages 6 is topmost, vent passages 6 top produces negative pressure by exhaust blower 8, by the natural flow shape mixing wind of negative pressure, hot blast and natural wind, the heat that frequency converter radiator is produced is discharged rapidly, reaches the optimum efficiency of cooling.
The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
