Problems solved by technology

The air-cooled system has a simple structure and small volume, but it is noisy, and the temperature of the system cannot be lowered below room temperature. The heat dissipation performance is far inferior to that of water cooling and oil cooling.
The oil-cooled heat dissipation system has high efficiency, but it has problems such as pollution and flammability
Compared with the above two heat dissipation methods, the water cooling system has the hi...

Abstract

The invention discloses a circulation cooling pipeline of a three-level power module of an integrated gate commutated thyristor; a plurality of radiator circulation cooling pipelines are formed by connecting a capillary hose with a water-supply header, a backwater header and a square water-cooling radiator; and the capillary hose is further connected with the water-supply header, the backwater header, a water-cooling reactor of the three-level power module of the integrated gate commutated thyristor and a water-cooling resistor to form a plurality of impedance circulation cooling pipelines. The circulating water flows through the square water-cooling radiator, water-cooling resistor and water-cooling reactor in a power module unit so as to cool a main power heating power electronic devicein the power module, the radiating efficiency is greatly improved, thereby effectively protecting the power electronic device and guaranteeing the normal operation of a system; and the water circulating pipeline is simple in structure, material-saving and easy to replace.

Description

technical field [0001] The invention relates to a circulation cooling pipeline, in particular to a circulation cooling pipeline of an integrated gate commutation thyristor three-level power module. Background technique [0002] As the main working component of the high-power converter, the integrated gate-commutated thyristor three-level power module unit will generate a lot of heat during operation, which will increase the temperature of its internal power electronic devices. If the heat dissipation system cannot meet the heat dissipation requirements , will lead to system performance degradation, and even cause damage to power electronic devices, resulting in the paralysis of the entire system. At present, in the cooling system of high-power converters, there are mainly three methods of air cooling, oil cooling and water cooling. The air-cooled system has a simple structure and small volume, but it is noisy and cannot lower the temperature of the system below room tempera...
