| 摘要 |
The present invention provides a rectifier which changes only the cooling capacity of a second cooling module if the capacity of the rectifier is changed by a complete separation structure of a first cooling module and the second cooling module and includes a separated cooling module for efficiently performing maintenance and repair and increasing the lifetime of a product. Also, the present invention overcomes the existing weakness of water and dust due to an increase in a gap of a vent and provides the rectifier which includes the separated cooling module with IP standards and IP54 levels or less. [Reference numerals] (AA) Heated cooling water flows out;(BB) Cooled cooling water flows in |
