  • Publication number: 20210307199
    Abstract: Techniques for heat exchanger networks are disclosed. In the illustrative embodiment, several heat exchangers and several components to be cooled are connected together in a network. The flow of liquid coolant to each component and heat exchanger can be individually controlled. If a particular component needs more or less cooling, the flow rate of coolant through that component can be controlled. If a first component needs more cooling and a second component can operate with less cooling, coolant may be rerouted from the first component to the second component. Thus, target temperature load balancing can be achieved for all the components of the system. If a heat exchanger is faulty, it can be isolated, and a backup heat exchanger can be brought online, making the system self-healing and fault-tolerant. The faulty heat exchanger can then be repaired or replaced while the rest of the system is operational.
