This invention provides a clustered reaction system, comprises a plurality of reactors, a cooling device, and a gas supply device wherein said reactors are arranged at a distance from each other, said cooling device is used to supply cooling liquid to the heat exchange channels of said reactors, said gas supply device is used to supply gas to the reactors. By connecting multiple reactors in parallel and share a cooling device and a gas supply device, these reactors can be controlled more effectively and more efficiency to prepare quantum dots. |
