Drilling-fluids, called Drilling-mud, are used in drilling operations and in some cases become hot, generating difficulties in the operation. A system has been invented for cooling drilling-mud prior to returning it to the drilling operation for reuse. The new system consists of a cooling aggregate, a heat-exchanger and a drilling-mud throughput system. The cooling aggregate is used to cool process cooling-fluid circulated through a heat-exchanger. The heat-exchanger is designed with cooling- plates, prepared with cavities for circulation of the cooling-fluid. These cooling plates are stacked over each other and spaced apart in such a way that they do not plug and thereby avoid improper throughput when the drilling-mud, with its high temperature and consistency, is passed through: The drilling-mud, coming from the drilling operation, is treated and improved to meet the drilling operation requirements. After treatment; the drilling-mud enters the system and is passed through the heat-exchanger, reducing its temperature prior to returning to the drilling operation.
