The cooling module comprises a main supply connector, a main return connector, an internal cooling loop, a plurality of cooling plates, a base layer and a lid. The base layer includes a plurality of supply sub-connectors and return sub-connectors and a plurality of cooling areas corresponding to a plurality of cooling plates. Each cooling plate has a supply connector, a return connector and a contacting area. The plurality of supply sub-connectors and return sub-connectors are connected with the internal cooling loop. Each cooling area is to contact with a contacting area of a corresponding cooling plate. Each supply sub-connector is to be connected to a supply connector of the corresponding cooling plate, and each return sub-connector is to be connected to a return connector of the corresponding cooling plate. The corresponding cooling plate is to be removably attached with the base layer and to be serviced independently.
