Abstract
The invention discloses a dual circulation cooling cooler on the hot side of a heat pipe wind generating set, which comprises a heat pipe bundle, a fan on the cold side, a circulating fan on the hot side and a wind scooper. The heat pipe bundle is arranged on the top plate of a generator room and is divided into two parts; and the circulating fan is arranged in the generator room. The dual circulation cooling cooler has the advantages that: firstly, the two centrifugal fans positioned in the generator room ensure that the air in the generator room forms a main circulating air passage and an auxiliary circulating air passage, which are convenient for the heat generated by the generating set to be immediately transferred to the heat pipe bundle. The motor of the centrifugal fan adopts external type; therefore, the influence on the service life of the motor by high temperature is avoided. Secondly, the integral structure is compact, the volume is small, and the weight is light. Thirdly, the heat pipe adopts a composite pipe with copper and aluminum in the outer layer and the inner layer respectively, the aluminum pipe in the outer layer forms a fin through cold rolling process, therefore the heat-transfer area of the heat pipe is effectively increased. Fourthly, taking the accidental release of the heat pipe into consideration, a liquid collecting device and a liquid level alarming device are installed in the generator room. Fifthly, desiccant is arranged in the generator room, which can keep dry of the air in the generator room and ensure the normal operation of the generating set.
Description
Technical field
The present invention relates to the heat pipe wind generating unit cooler of the two circulation types of cooling of a kind of hot side, specifically a kind of heat-pipe type cooling apparatus.
Background technology
Wind turbine generator produces a large amount of heats in the course of the work, and these heats must lose as early as possible, to ensure that generating set is not overheated, also to run well.
Wind turbine generator cooler commonly used now has the light pipe Pipe bundle structure, the heat transferred tube bank that generating set produces, and the cooling air by the outside cools off again.This heat exchanger structure is simple relatively, though reliability is fine, the heat exchange effect is undesirable, and the big and heavy of volume is brought very big inconvenience to installation and removal.
Some wind turbine generator cooler also, the heat transferred that generating set is produced is arranged in water radiator or the oil radiator in the generator casing earlier, and then dispels the heat by the heat exchanger of generator case outside.This structure is relatively complicated, and heat exchange efficiency has bigger decline through several transmission, and volume is big, heavy, also the risk that existence is leaked or leakage of oil brings.
Summary of the invention
What the present invention will solve is the above-mentioned defective that prior art exists, and aims to provide a kind of heat-pipe type radiator.
The technical scheme that addresses the above problem employing is: the bicirculating heat pipe wind generating unit of a kind of hot side cooler, comprise heat pipe tube bank, cold side blower fan and hot side circulating fan, described heat pipe is restrained on the top board that is arranged on the generator bay, and is divided into two parts by top board; Described circulating fan is arranged on generator bay and restrains a side near the bottom heat pipe; The cold side blower fan is positioned at the downwind side of top heat pipe tube bank, is axial flow blower, and working method is the air draught cooling; Hot side circulation is divided into major cycle and attached circulation in generator bay, and major cycle is through the generator unit stator gap, again through the outlet circulation of generator unit stator top, and attached circulating air circulates through the passage of generator bay away from hot side circulating fan one side.
The bicirculating heat pipe wind generating unit of hot side of the present invention cooler, with the generator bay upper plate is that dividing plate is divided into two parts with the heat pipe tube bank, the latter half is installed in the generator casing, the evaporation section of the heat transferred heat pipe tube bank of generating set being sent by hot side circulating fan.Heat upwards is delivered to condensation segment by the evaporation section of heat pipe again, and the cooling blower outside generator bay cools off, and heat is taken away.
Advantage of the present invention is as follows:
1) cooling blower in the generator casing cabin can make that air effectively forms major cycle and attached circulation in the cabin, and the heat that helps generating set to produce is immediately passed to the heat pipe tube bank.
2) compact overall structure, volume is little, and is in light weight.
3) the cold side blower fan is positioned at heat pipe tube bank downwind side, and this type of cooling makes when cooling air is flowed through the heat pipe tube bank more even, and cooling effect is preferably arranged.
As a further improvement on the present invention, copper water-bound, low, the stable performance of cost, no corrosiveness are adopted in the heat pipe tube bank.After adding an amount of 60～80 order water smoke copper powders, go back the low ambient temperature of ability-40 degree.
Further improve again as of the present invention, circulating fan in the generator bay is positioned at generator bay one side, promote hot-air and form main, attached two circulations, the heat that the electric machine external mode helps the generating set generation is immediately passed to the heat pipe tube bank, ensures the long-term operate as normal of blower fan.
Further improve as of the present invention, the heat pipe of heat pipe tube bank is the composite pipe structure of the outer aluminium of interior copper, and outside aluminum pipe forms continuous helical fin through cold-rolling process, has effectively increased the Heat Transfer of Heat Pipe on Heat Pipe area.
Further improve as of the present invention, heat pipe tube bank bottom also is equipped with the liquid collecting pallet, can guarantee the heat pipe accidental release after water can not flow on the generator, cause short circuit accident.
Further improve as of the present invention, the liquid collecting pallet has liquid level alarm device, can in time find and remove a hidden danger when guaranteeing alarm signal is arranged.
Further improve as of the present invention, generator bay also is provided with drier, to guarantee the cabin inner drying, ensures that generator runs well.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of heat pipe wind generating unit cooler.
Fig. 2 is hot quencher moiety schematic diagram.
Embodiment
With reference to accompanying drawing, the bicirculating heat pipe wind generating unit of hot side of the present invention cooler, mainly comprise heat pipe tube bank 1, cold side blower fan 2, hot side circulating fan 3 and cold side wind scooper 15, described heat pipe tube bank 1 is arranged on the top board 11 of generator bay, and be divided into up and down two parts by it, top board upper section 13 is a cold side, and below part 12 is hot side.Because heat pipe is restrained the latter half of 1 in generator bay 6, generator bay 6 good seals.
According to generator bay 6 radiating requirements, air circulation in the cabin is divided into major cycle and attached circulation, two centrifugal blowers 3 are positioned at generator bay and restrain a side near heat pipe, major impetus for hot side circulation, major cycle circulates through the outlet 8 of generator unit stator top, the attached circulating air passage 7 of flowing through guarantees that generator shaft is not overheated.Outside cooling blower 2 is positioned at heat pipe and restrains 1 downwind side, and cooling air is restrained a side draught by heat pipe and come in, and discharges through axial flow blower then.
The heat pipe of heat pipe tube bank 1 is the composite pipe structure of the outer aluminium of interior copper, and outside aluminum pipe forms continuous helical fin through cold-rolling process.
The bottom of heat pipe tube bank is supported and the location with carriage 14, guarantees that every heat pipe can not rock.Carriage 14 is fixed on the liquid collecting pallet 4, and described liquid collecting pallet 4 has collecting tank and liquid level alarm device 5.
Be provided with drier 10 at generator bay 6, be convenient to regularly change, guarantee generator bay 6 dryings.
