Problems solved by technology

[0003] At present, the current domestic situation is that the medium and low voltage thyristor valves are cooled by air cooling or oil cooling. The disadvantages are that the system is huge, the cooling efficiency is low, the initial investment is large, the maintenance of the system is difficult, and there is pollution to the environment.
In particular, water-cooled radiators can only be used in low-voltage and low-power rectification systems, and have large thermal resistance, low efficiency, and short life

Embodiment Construction

[0030] See Figure 1. The thyristor valve water-cooled radiator adopts a flat surface contact heat transfer structure. The parallelism of the two tables of the water-cooled radiator is within 0.02mm, and the surface roughness of the two tables is below 1.6μm, which can improve the microscopic heat transfer area and heat transfer efficiency. , At the same time, it can ensure that the number of crimping thyristor valves and water-cooled radiators reaches more than 20 strings.

[0031] The interface of the cooling water pipe is one in and one out, so as to reduce the number of water distribution pipes at the interface, simplify the layout and facilitate installation.

[0032] The built-in pipe of the water-cooling radiator is close to the table to shorten the heat transfer stroke and dissipate heat in time.

[0033] There are dedicated wire connection holes and installation fixing holes outside the table of the water-cooling radiator.

[0034] The built-in pipes of the water-cool...

Abstract

The invention relates to a thyristor valve group water cooling radiator in the field of electronic technology. It adopts plate touching conduction structure with the parallel degree of the two plates below 0.02 mm and the surface crudity degree below 1.6mum; The interface of the cooing water pipe is an entrance and a exit; the embed canal apprises the plate; it arranges the special wire connecting hole and fixed hole. The embed canal material uses low carbon stainless steel pipe and adds the element which can elevate the compression strength in the aluminum alloy of the plate. It adopts special embed canal surface processing craft and casing surface aluminum alloy electroplating craft.

Description

technical field [0001] The invention relates to a thyristor valve group of a core device of a static var compensator (SVC) in a power system and power electronic technology, in particular to a thyristor valve water-cooled radiator. Background technique [0002] Following the expansion and reconstruction of the power network, as well as the improvement of human requirements on the quality of electricity, medium and high voltage high power transmission and transformation systems will be widely used. Cooling technology has been a bottleneck restricting the development of related power electronic products in power systems for many years. No effective product has been developed in China, and cooling components have been imported for a long time. [0003] At present, the domestic situation is that the medium and low voltage thyristor valves are cooled by air or oil. The disadvantages are that the system is huge, the cooling efficiency is low, the initial investment is large, the m...
