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 is exposed to atmospheric pressure in the embodiment being described. The venturi, when used with a pressure switch, can operate to determine a flow rate which can be used to generate a signal which in turn is used to activate or deactivate one or more of the components, such as the heat-generating component, in the system. Advantageously, the design of the embodiment described has a convenient system which utilizes a pressure switch, thereby eliminating the need for a differential pressure switch of the type used in the past.
Claims57
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.
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.
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 component;
- 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.
The X-ray system as recited in claim 33 wherein said switch is located either upstream or downstream of said venturi and upstream of said pump.
A method for cooling a component situated in a system;
- said method comprising the steps of:
- providing a conduit coupled to said component;
- coupling said component casing to a pump for pumping a cooling fluid through said conduit and to a heat-rejection component;
- increasing a boiling point of said cooling fluid, thereby increasing an operating temperature of said X-ray system.
A method for cooling a component situated in a system;
- said method comprising the steps of:
- providing a conduit coupled to said component;
- coupling said component casing to a pump for pumping a cooling through said conduit and to a heat-rejection component;
