Abstract
The invention discloses a cooler for a hot plate-type wind generating set, which comprises a hot-side part and a cold-side part. The cooler is characterized in that the hot-side part comprises a heat absorption fin, a lower hot plate and a hot-side circulating fan which are arranged in a generator box body; the cold-side part comprises an upper hot plate, a heat tube bundle, a cold-side fan and a cold-side wind guiding cover; and the upper hot plate is arranged on the lower hot plate and is communicated with the heat tube bundle. The cooler has the advantages that 1) cooling fans in the generator box body are arranged on both sides of the heat absorption fin, the temperature is low relatively, and the requirement on a fan motor is low relatively; 2) the cooler has a compact structure, small volume and light weight; and 3) heat tubes with copper water structures and the hot plates have low cost, are stable, have no corrosive action, and can resist the low temperature of -40 DEG C.
Description
Technical field
The present invention relates to a kind of wind turbine generator cooler, specifically a kind of hot plate type cooler.
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 brings very big inconvenience for the empty installation and removal of wind tower height.
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 transmitting several times, 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 hot plate type radiator.
The technical scheme that addresses the above problem employing is: a kind of hot plate type wind turbine generator cooler, comprise hot side and cold side part, it is characterized in that described hot side comprises the heat absorption fin that is arranged in the generator casing, following hot plate and hot side circulating fan; Described cold side partly comprises hot plate, heat pipe tube bank, cold side fan and cold side wind scooper, and the described hot plate of going up is arranged on the described hot plate down, and communicates with described heat pipe tube bank.
Hot plate type wind turbine generator cooler of the present invention, cooler is divided into hot side and cold side two parts, and the hot side is installed in the generator casing, is made up of heat absorption fin, following hot plate, the heat that generating set produces is driven by the hot side circulating fan of heat absorption fin both sides, passes to the heat absorption fin; The cold side part is made up of last hot plate and heat pipe tube bank, and last hot plate communicates with the heat pipe tube bank, and promptly every heat pipe cavity all communicates with last hot plate cavity, constitutes an integral body.Heat passes to hot plate by following hot plate, losing through the cooling fan cooling by the heat pipe tube bank again.
Advantage of the present invention:
1) cooling fan in the generator casing is placed in heat absorption fin both sides, and temperature is relatively low, requires relatively low to fan electromotor.
2) compact overall structure, volume is little, and is in light weight.
3) heat pipe of copper water-bound and hot plate, cost is low, very stable, no corrosiveness, the also low temperature of ability-40 degree.
As a further improvement on the present invention, described heat absorption fin both sides are equipped with hot side circulating fan, the heat that hot side generating set produces is driven by hot side circulating fan, from the heat absorption fin of upwards flowing through after the generating set stator gap is come out, to two side flow, form two symmetrical cycle, with heat by hot plate under the passing to of heat absorption fin both sides.
Further improve as of the present invention, last hot plate and following hot plate employing copper water make up, and add a certain amount of 60～80 purpose water smoke copper powders again, guarantee that the present invention also can operate as normal in-40 ℃ even lower environment.
Further improve again as of the present invention, every heat pipe of heat pipe tube bank and last hot plate welding together, its cavity communicates with last hot plate cavity.
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 again, and outside aluminum pipe forms continuous helical fin through cold-rolling process.
Further improve again as of the present invention, adopt bolt between last hot plate and the following hot plate.
Further improve as of the present invention, heat absorption fin, following hot plate, the contact-making surface of going up between hot plate, the heat pipe tube bank require flatness＜0.4, and coated with thermally conductive glue.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of wind turbine generator hot plate type cooler.
Fig. 2 is hot quencher moiety schematic diagram.
Fig. 3 is a hot quencher moiety schematic diagram of removing cold side wind scooper and hot side body.
Embodiment
With reference to accompanying drawing, a kind of hot plate type wind turbine generator cooler comprises hot side and cold side part, it is characterized in that described hot side comprises the heat absorption fin 1 that is arranged in the generator casing 9, following hot plate 2 and hot side circulating fan 3; Described cold side partly comprises hot plate 6, heat pipe tube bank 5, cold side fan 4 and cold side wind scooper 8, and the described hot plate 6 of going up is arranged on the described hot plate 2 down, and restrains 5 cavitys with described heat pipe and communicate.
Last hot plate 6 directly contacts with following hot plate 2, and passes through screw.Last hot plate 6 and following hot plate 2 adopt the combination of copper water, and add a certain amount of 60～80 purpose water smoke copper powders.Between last hot plate 6 and the following hot plate 2, down hot plate 2 has very high flatness between the fin 1 with absorbing heat, require flatness＜0.4 usually, and be coated with heat-conducting glue.
The heat pipe of heat pipe tube bank 5 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 every heat pipe and the last hot plate 6 of heat pipe tube bank 5 weld together.
Described heat absorption fin 1 both sides are equipped with hot side circulating fan 3, the heat that hot side generating set produces is driven by hot side circulating fan 3, from the heat absorption fin 1 of upwards flowing through after the generating set stator gap is come out, to two side flow, in generator bay 10, form two symmetrical cycle, with heat by hot plate 2 under the passing to of heat absorption fin 1 both sides.The heat that generating set produces passes to hot plate 6 by hot plate 2 down, restrains 5 by the heat pipe that links together with last hot plate 6 again, cools off by cold side fan 4.
