A modular heat exchanger has a movable enclosure and a heat exchanger and a pump inside the enclosure. The low temperature side of the heat exchanger is connected to a chilled water supply. The high temperature side of the heat exchanger is connected in a circuit with the pump and water-cooled components of a data processor. Manifolds interconnect several of the modular units. A common expansion tank is connected to the high temperature side. Valves permit individual modules to be disconnected for service. The system of isolation valves includes valves of the type that are ordinarily operated by air pressure or hydraulic fluid. These valves are connected to be operated by the pressure rise across the inlet and outlet of a pump. These valves are opened when a pump is started, and they close automatically when a pump stops.
