Embodiment Construction

[0026] Such as Figure 1 to Figure 3 As shown, an embodiment of a water-cooled radiator for power electronic power components, the water-cooled radiator in this embodiment includes a radiator body 1, and the radiator body 1 is provided with a water-cooling channel 2 and an inlet corresponding to the water-cooling channel 2 The water hole 3 and the drain hole 4, when in use, the cooling water enters the water cooling channel 2 through the water inlet hole 3, and then is discharged through the drain hole 4, so as to realize the cooling and heat dissipation of the power electronic power components.

[0027] What is different from the water-cooled radiator in the prior art is that in this embodiment, the water inlet hole 3 and the drain hole 4 are all sealed installation holes equipped with a sleeve-shaped equalizing electrode 7, and the equalizing electrode 7 here The pole 7 has an inner hole for the cooling water to flow through to ensure the normal circulation of the cooling wa...

Abstract

The invention provides a water-cooling radiator for an electric power electronic power element. The water-cooling radiator includes a radiator body, a water-cooling channel and a water inlet and a drain hole which are correspondingly communicated with the water-cooling channel are arranged on the radiator body, the water inlet and / or the drain hole are equipped with sleeve-shaped mounting holes of voltage-sharing electrodes in a sealing manner, and the voltage-sharing electrodes have inner holes for cooling water to flow through. The voltage-sharing electrodes can guarantee normal circulation of the cooling water in the mounting holes, and at the same time, due to functions of the voltage-sharing electrodes, electric field distribution around of the radiator can be controlled, and leakage current generated in a loop is attracted to the voltage-sharing electrodes, thereby preventing corrosion from being caused to the inside of the radiator body, guaranteeing normal conduction of the water-cooling channel, and guaranteeing normal operation of the water-cooling radiator.

Description

technical field [0001] The invention relates to a water-cooled radiator for power electronic power components. Background technique [0002] Due to the high power of high-power electronic power components, the loss increases accordingly. In order to ensure that the power is used at its normal operating temperature, forced water cooling is often used to cool it through the radiator. [0003] Commonly used water-cooled radiators, such as the radiator disclosed in the Chinese utility model patent whose authorization announcement number is CN201450002U, include a body. The lower water cooling chamber and the return water passage communicated with the lower water cooling chamber, and the body is also provided with a longitudinal channel connecting the upper and lower water cooling chambers. When in use, the circulating cooling water quickly flows in the upper and lower water cooling chambers, which can absorb the heat on the body to the maximum extent, and realize the cooling an...
