  • Coolant circuit manifold for a tractor-trailer truck
    Patent number: 9631545
    Abstract: A tractor-trailer truck engine coolant manifold comprises a first supply port for receiving coolant from an engine or radiator, and a first return port for returning coolant to the engine or radiator. The manifold also has a second supply port in fluid communication with the first supply port, and a second return port in fluid communication with the first return port. Further, the manifold can have a third supply port in fluid communication with the first supply port, and a third return port in fluid communication with the first return port. The coolant manifold can further have one or more internal flow paths that are configured so that coolant flow rate or pressure exiting one supply port is different from the coolant flow rate or pressure exiting from another supply port, pre-selected based upon the thermal requirements of the heat source or heat sink components.
