Embodiment Construction

[0020] With reference to the accompanying drawings, the heat pipe type wind turbine cooler of the present invention includes a heat pipe bundle 1, a cold side fan 2, a hot side circulation fan 5 and a cold side air guide cover 3, and the heat pipe bundle 1 is arranged on the generator cabin 7 The top plate 6 is divided into two parts, the top plate 6 is the cold side, and the bottom is the hot side. Since the lower half of the heat pipe bundle 1 is in the generator compartment 7, the generator compartment 7 is well sealed.

[0021] According to the characteristics of the two-way air circulation in the generator cabin 7 , the heat pipe bundle 1 is divided into two parts, and the external cooling fan 2 is located in the middle of the heat pipe bundle 1 . The hot-side circulating fan 5 in the generator cabin 7 is located above the generator, and an air deflector 4 is arranged above the hot-side circulating fan 5, and the air path is divided into two cycles by the air deflector 4....

Abstract

The invention discloses a cooler of a heat pipe type wind generating set, comprising a heat pipe bundle, a cold-side fan, a hot-side circulating fan and a cold-side wind scooper, wherein the heat pipe bundle is arranged on a top plate of a power generating room and is divided into two parts, and the hot-side circulating fan is arranged into the power generating room. The invention has the advantages that: (1) a cooling fan can lead air to effectively form two circulating air paths in the power generating room and is helpful to immediately transferring heat generated by the wind generating set to the heat pipe bundle; (2) an integrated structure is compact and has small volume and light weight; and (3) the heat pipe is an inner-copper and outer-aluminum compound pipe, and an outer-layer aluminum pipe forms fins after carrying out a cold rolling process, therefore, the heat transfer area of the heat pipe is effectively increased.

Description

technical field [0001] The invention relates to a heat pipe cooler for a wind power generating set, in particular to a heat pipe 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 kind of heat exchanger has a relatively simple structure, and although it has good reliability, the heat exchange effect is not ideal, and the volume is large and the weight is heavy, which brings great inconvenience to installation and disassembly. [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 then dissipate heat throu...
