Problems solved by technology
[0003] The heat dissipation efficiency of traditional water-cooled reactors depends on the number of water-cooled modules. In order to reduce the temperature rise of the reactor, it is necessary to increase the number of water-cooled modules in the line package, resulting in larger reactor volume and increased cost.

Embodiment Construction
[0019] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.
[0020] figure 1 It is a front view of a heat pipe heat-conducting water-cooled reactor provided by the present invention. The heat pipe heat-conducting water-cooled reactor includes a stem 2, and the stem 2 is formed by cutting silicon steel sheets of the same width into small pieces and stacking them. A core column is composed of multiple core blocks, and a non-magnetic insulating material is placed between the core blocks as an air gap plate 13 to adjust the inductance; the air gap plate 13 and the core blocks are filled with high-temperature resin glue for bonding. The lower iron yoke 14 is installed on the lower part of the core column 2, and the upper iron choke 1 is installed on the upper part of the core column 2 through the air gap plate 13. Iron core splints 3 are installed on both sides of the core column 2, the upper ir...

Abstract
The inventionprovides a water-cooled reactor with heat conducted by heat tubes. The water-cooled reactor comprises a stem. A lower yoke is arranged at the bottom of the stem. An upper yoke is disposed at the top of the stem through an air gap plate. Core clamp plates are arranged on two sides of the stem, the upper yoke and the lower yoke. A coil is arranged outside the core clamp plates. The water-cooled reactor is characterized in that a heat tube plate is disposed between the coil and the core clamp plates, insulating paper or insulating film is disposed on the outer wall of the heat tube plate, heat tube plates are also evenly disposed in the coil, insulating paper or insulating films are arranged among the heat tube plates and copper (aluminum) tape turns of the coil, an outgoing strip is connected with copper (aluminum) tapes of the coil, and an unidirectional weftless tape is arranged outside the coil, and an external water-cooling plate is arranged at exposed heat-release ends of the heat tube plates and is connected with a water distributor at the top of the upper yoke through a water tube. The water-cooled reactor with heat conducted by heat tubes overcomes the defects of the prior art, fine radiating effect is achieved by the use of the heat tube plates, and the water-cooled reactor with heat conducted by heat tubes is 20-30% smaller than the traditional water-cooled plate reactor in size.
Description
technical field [0001] The invention relates to a heat pipe heat conduction type water-cooled reactor, which is used in a wind power converter and belongs to the technical field of three-phase low-voltage AC reactors. Background technique [0002] The water-cooled reactor used in the traditional wind power converter generally uses a water-cooled module embedded in the wire package to dissipate heat, and the water-cooled module uses an aluminum alloy material with an internally opened pipeline structure. In order to reduce water resistance, the minimum thickness of the water cooling module can only be 15-20mm. [0003] The heat dissipation efficiency of a traditional water-cooled reactor depends on the number of water-cooled modules. In order to reduce the temperature rise of the reactor, it is necessary to increase the number of water-cooled modules in the wire package, resulting in larger reactor volume and increased cost.
