PARALLEL EVAPORATOR CIRCUIT WITH BALANCED FLOW

摘要

Provided is a pumped loop system (10) for cooling a heat-generating components without relying on a maximum heat load, the system including first and second evaporators (14a-14n) in parallel with one another and first and second valves (22a-22n) upstream of the first and second evaporators respectively, wherein the valves (22a-22n) are controllable to vary the flow rate of fluid to the respective evaporator (14a-14n) based on the amount of flow needed to control the respective heat-generating component. By cooling the heat-generating components without relying on the maximum heat load, adequate flow may be provided to an evaporator operating under a high heat low while reduced flow is provided to an evaporator operating under a low head load.

1. A pumped loop system for cooling heat-generating components including:
a first branch having a first evaporator for absorbing heat from a first heat-generating component having a variable heat load and a first valve upstream of the first evaporator for variably controlling the flow of fluid to the first branch; a second branch parallel to the first branch, the second branch having a second evaporator for absorbing heat from a second heat-generating component having a variable heat load and a second valve upstream of the second evaporator for variably controlling the flow of fluid to the second branch; a pump for pumping fluid to the first and second branches; a condenser downstream of the first and second branches and upstream of the pump for rejecting the heat absorbed by the fluid in the first and second branches; and at least one controller configured to control at least one of the first valve and the second valve.
