Embodiment Construction

[0022] Referring to the accompanying drawings, a hot-plate cooler for wind turbines includes a hot-side part and a cold-side part. 2 and hot-side circulation fan 3; the cold-side part includes an upper hot plate 6, a heat pipe bundle 5, a cold-side fan 4 and a cold-side wind guide hood 8, and the upper hot plate 6 is arranged on the lower heat plate 2, and communicate with the cavity of the heat pipe bundle 5.

[0023] The heat-absorbing fins 1 and the lower heat plate 2 are fixed on the upper top plate of the generator case 9 by bolts, and form a closed cavity together with the generator case 9 .

[0024] The upper hot plate 6 is in direct contact with the lower hot plate 2 and fixed by screws. The upper hot plate 6 and the lower hot plate 2 are combined with copper water, and a certain amount of 60-80 mesh water mist copper powder is added. There is a high flatness between the upper heating plate 6 and the lower heating plate 2, and between the lower heating plate 2 and th...

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 [0001] The invention relates to a cooler for a wind power generating set, in particular to a hot plate cooler. Background technique [0002] Wind turbines generate a lot of heat during work, which must be dissipated as soon as possible to ensure that the generators do not overheat and operate normally. [0003] Now commonly used wind turbine coolers have a bare tube bundle structure, the heat generated by the generator set is transferred to the tube bundle, and then cooled by external cooling air. This type of heat exchanger has a relatively simple structure, and although it has good reliability, the heat exchange effect is not ideal, and it is large in size and heavy in weight, which brings great inconvenience to the high-altitude installation and disassembly of the wind tower. [0004] There are also some wind turbine coolers that first transfer the heat generated by the generator to the water radiator or oil radiator arranged in the generator box, and the...
