Abstract: Disclosed herein is a cooling system for a chamber of an ingot growth apparatus. In the present invention, guide blades (180) are provided in a base plate (100) at positions adjacent to unevenly curved parts of a guide line (170), which is the base plate (100), and along which cooling water flows. Furthermore, guide blades (360) are provided in a lid (300) at positions adjacent to ports, which are provided in the lid (300) and interfere with the flow of cooling water. As such, in the present invention, the guide blades are provided in the base plate (100) and the lid (300), which define the chamber, at positions at which cooling water creates stationary vortices, thus solving a problem of water stagnation, thereby increasing a cooling effect.
