Abstract
A system and method for improving cooling of a heat-generating component in a closed-loop cooling system is shown. The system comprises a venturi having a throat which is coupled to an expansion tank that may be exposed to atmospheric pressure in the embodiment being described. A closed expansion tank may be provided in the system to force or continue to cause fluid flow to cool the heat-generating component after a pump stops.
Claims42
A method for increasing pressure in a closed-loop system comprising a pump for pumping fluid in said system, a heat-generating component and a heat-rejection component, said method comprising the steps of:
- situating a venturi in series in said closed-loop system;
- and
- providing a predetermined pressure at a throat of said venturi;
- using said pump to cause flow in said closed-loop system in order to increase pressure in said system, thereby increasing said boiling point of the fluid, said overall pressure being greater than said predetermined pressure;
- providing an accumulator and a valve to cause fluid to be passed to said heat-generating component when said pump is not pumping.
A cooling system for cooling a component comprising:
- a heat-rejection component;
- a pump for pumping fluid to said heat-rejection component and said component;
- a conduit for communicating fluid among said component, said heat-rejection component and said pump, said conduit comprising a venturi having a predetermined pressure applied at a throat of said venturi;
- a closed expansion tank coupled to said conduit;
- and
- a valve coupled to said conduit;
- said valve and said closed expansion tank cooperating to cause flow in said conduit to cool the component when said pump is deactivated.
An X-ray system comprising:
- an X-ray apparatus for generating X-rays, said X-ray apparatus comprising an X-ray tube situated in an X-ray tube casing;
- and
- a cooling system for cooling said X-ray tube, said cooling system comprising:
- a heat-rejection component coupled to said X-ray tube casing;
- a pump for pumping fluid to said heat-rejection component and said x-ray tube casing;
- a conduit for communicating fluid among said X-ray tube casing, said heat-rejection component and said pump, said conduit comprising a venturi having a predetermined pressure applied at a throat of said venturi, an expansion tank;
- a closed expansion tank located between said pump and said heat-rejection component;
- and
- a valve located between said pump and said closed expansion tank.
