Problems solved by technology

[0004]However, some inverter power modules do not have insulating plates attached to the sides. At this time, the water tank in the damping module of the above-mentioned bridge arm does not form a foundation, and water seeps from the top cover plate. After seeping out of the gap between the joint hole on the top surface and the water pipe joint, it is easy to flow along the outline of the plate radiator, which may contact the electrical components and affect the operation of the bridge arm damping module

Embodiment Construction

[0056] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0057] A specific embodiment of the converter power module in the present invention, such as figure 1 and figure 2 As shown, the converter power module includes a water-cooled radiator 1 and a capacitor 17 , and there is a gap between the water-cooled radiator 1 and the capacitor 17 . The water-cooled radiator 1 is a plate-type radiator arranged vertically, and the inside electrical parts 2 are arranged on both sides of the board. spacing. The converter power module also includes a top cover plate 3 covering the top of the water-cooling radiator 1 , and the top cover plate 3 is used to protect the inner electrical components 2 and the water-cooling radiator 1 .

[0058] The top of the water-cooled radiator 1 is provided with a water outlet and a water inlet, and the water outlet and the water inlet are respectively connected with the return water pip...

Abstract

The invention relates to a converter power module and a water-cooling radiator thereof. The water-cooling radiator for the converter power module comprises a cooling liquid pipeline connector arranged at the top; a groove is formed in the top of the water-cooling radiator; the cooling liquid pipeline connector is arranged at the bottom of the groove; a water guide channel is formed in the top of the water-cooling radiator; one end of the water guide channel is communicated with the groove; the other end of the water guide channel extends to the side surface of the water-cooling radiator; and a water flowing groove communicated with the water guide channel is formed in the side face of the water-cooling radiator and extends to the bottom of the water-cooling radiator. Water seepage at the joint of the cooling liquid pipeline connector and the water-cooling radiator is collected through the groove in the top of the water-cooling radiator, and the water seepage in the groove is guided to the position below an electric appliance element through the water guide channel and the water flowing groove, so that the water seepage is prevented from flowing along the outline of the water-cooling radiator and possibly making contact with the electric appliance element to influence operation of the electric appliance element, and therefore, the reliable operation of the converter power module is ensured.

Description

technical field [0001] The invention relates to a converter power module and a water cooling radiator thereof. Background technique [0002] The converter power module is the main component of the entire flexible DC distribution network system. It plays a key role in connecting the AC system and the DC system and realizing the mutual conversion of AC and DC energy. The reliable operation of the converter power module directly affects Reliability of energy transmission throughout the system. [0003] In the prior art, water cooling is usually used to dissipate heat from the converter power module. For example, a Chinese invention patent with the authorized announcement number CN106921300B and the authorized announcement date on February 1, 2019 discloses a bridge arm damping module and a bridge arm damping module with the bridge The diverter valve of the arm damping module, the water cooling radiator in the bridge arm damping module is a vertically arranged plate-shaped radi...
