SCR radiator structure of 誘導溶解炉

SCRラジエーター構造：水冷キャビティ+マルチ銅ピラーサポート。 循環水が硬すぎると、水槽内でスケーリングし、熱放散が不十分になります。 葉やその他の破片が水空洞に入ると、水の流れも悪くなります。

The factory test temperature of the thyristor is 100°C (junction temperature). Under normal circumstances, the circulating water temperature of the intermediate frequency power supply is kept below 45°C to ensure its normal operation. The hand-held infrared thermometer is very useful. The 350℃ thermometer can measure the temperature of the thyristor and the temperature of the radiator in operation, which can detect abnormal points in time and deal with faults.

The mesa of the heat sink must match the size of the component mesa to prevent voltage bias and distortion, which may damage the device. The radiator countertop must have a high level of flatness and smoothness. It is recommended that the surface roughness of the radiator is less than or equal to 1.6mm, and the flatness is less than or equal to 30mm. During installation, the countertop of the component and the countertop of the radiator should be kept clean, clean and free of dirt such as oil.

When installing, keep the tabletop of the silicon component and the tabletop of the heat sink completely parallel and concentric. During the installation process, it is required to apply pressure through the center line of the component so that the pressure is evenly distributed throughout the contact area. When the user manually installs, it is recommended to use a torque wrench to alternately and uniformly apply force to all the tightening nuts, and the pressure must meet the specified requirements.

When reusing the water-cooled radiator, pay special attention to checking whether the countertop is smooth and flat, and whether there is scale and blockage in the water cavity, and pay special attention to whether the countertop is sinking. If the above situation occurs, it should be replaced.
