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...

The present invention provides a water-cooled radiator for electric and electronic power components, which includes a radiator body, a water-cooling channel and water inlet holes and drain holes correspondingly connected to the water-cooling channel are arranged on the radiator body, and the water inlet holes and / or The drain hole is a mounting hole sealed with a sleeve-shaped voltage equalizing electrode, and the voltage equalizing electrode has an inner hole for cooling water to flow through. The equalizing electrode can ensure the normal circulation of cooling water in the installation hole. At the same time, due to the effect of the equalizing electrode, it can control the electric field distribution around the radiator, and attract the leakage current generated in the circuit to the equalizing electrode. Effectively avoid corrosion to the inside of the radiator body, ensure the normal conduction of the water cooling channel, and ensure the 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...
