Abstract

A cooling pipeline and cooling apparatus for a converter. The cooling pipeline comprises a water inlet pipeline (1) and a water outlet pipeline (2). The water inlet pipeline comprises a water inlet main pipe (11) and a plurality of water inlet branch pipes (12). The water inlet main pipe is connected to a water pump (3). One end of the plurality of water inlet branch pipes is connected to the water inlet main pipe, and the other end of the plurality of water inlet branch pipes is connected to a water inlet opening of a water cooling substrate (62) for a power module of the converter. The water outlet pipeline comprises a water outlet main pipe (21) and a plurality of water outlet branch pipes (22). The water outlet main pipe is connected to a heat exchanger. One end of the plurality of water outlet branch pipes is connected to the water outlet main pipe, and the other end of the plurality of water outlet branch pipes is connected to a water outlet opening of the water cooling substrate for the power module of the converter. By designing a structure of a fitting main pipe and branch pipe for a water inlet pipeline and a water outlet pipeline, the number of pipelines can be reduced and the complexity of pipeline can be lowered, and also the installation space occupied by the pipelines can be reduced.

Description

technical field [0001] The invention relates to high-power converter technology, in particular to a converter cooling pipeline and a cooling device. Background technique [0002] High-power converter is one of the important components of AC drive system of electric locomotive. When the electric locomotive is running normally, the power device of the high-power converter realizes the conduction and shutdown of the circuit. The power device can be an insulated gate bipolar transistor (Insulated Gate Bipolar Transistor, referred to as IGBT) device or a semiconductor device such as a diode. When the power device is working The generated energy loss appears in the form of heat. If the heat generated by the power devices cannot be dissipated in a timely and effective manner, the working efficiency of the high-power converter will be affected, and the high-power converter may even fail to work. Therefore, appropriate cooling methods must be used to take away the heat generated by ...
