In the design of the medium frequency power supply for induction furnaces, water-cooled heatsinks must be used for the thyristors (SCRs). The models commonly used by Zhuzhou Yuanhang Industrial Furnace Technology Co., Ltd. are from the "SS" series of water-cooled thyristor heatsinks. In the "SS" series designation, the first "S" stands for heatsink, and the second "S" stands for water-cooled. This means water is used as the cooling medium, circulating to achieve heat dissipation for components like thyristors. Here is an introduction from Yuanhang Industrial Furnace regarding the selection criteria for thyristor water-cooling jackets, which are part of the water-cooled heatsink system.

When designing and selecting water-cooled heatsinks, our choice is based on the thyristor model, typically according to the thyristor's current rating. The common matching standards are as follows:
• SS11 Water-Cooled Heatsink: Generally used for thyristors rated at 100A, 200A, and 300A.
• SS12 Water-Cooled Heatsink: Generally used for thyristors rated at 300A, 500A, and 800A.
• SS13 Water-Cooled Heatsink: Generally used for thyristors rated at 800A, 1000A, and 1200A.
• SS14 Water-Cooled Heatsink: Generally used for thyristors rated at 1200A, 1500A, and 2000A.
• SS15 Water-Cooled Heatsink: Generally used for thyristors rated at 2000A, 2500A, and 3000A.
• SS16 Water-Cooled Heatsink: Generally used for thyristors rated at 3000A and above.
In practical use, it is generally advisable to choose a slightly larger heatsink to prevent potential damage to thyristors due to overheating.
Furthermore, within the same model series, there are single and dual configurations available. The single configuration can accommodate one thyristor, while the dual configuration can accommodate two. Using dual configurations for complete equipment installation is often more labor-saving and cost-effective. Users must clarify this during the design stage to avoid unnecessary complications.
