Supersonic cooling system
First Claim

1. A supersonic cooling system, comprising:
- a flow path having a high pressure region and a low pressure region;
a pump disposed at the high pressure region of the flow path, the pump facilitating the flow of fluid through the flow path; and
an evaporator that facilitates a phase change of a fluid traversing the flow path, wherein the low pressure region of the flow path is located within the evaporator, the pump feeds the fluid without having passed through a heater into the evaporator, and the flow path transports a flow of fluid at a velocity that is greater than the speed of sound in the fluid when the fluid undergoes the phase change as the fluid is transported from the high pressure region of the flow path to the low pressure region of the flow path.

Abstract
A supersonic cooling system operates by pumping liquid. Because the supersonic cooling system pumps liquid, the compression system does not require the use of a condenser. The compression system utilizes a compression wave. An evaporator of the compression system operates in the critical flow regime where the pressure in an evaporator tube will remain almost constant and then ‘jump’ or ‘shock up’ to the ambient pressure.

7. A cooling system, comprising:
-
a flow path; a pump that circulates a fluid through the flow path; and an evaporator that induces a pressure drop and phase change in the fluid as it is circulated through the flow path, wherein the pump feeds the fluid into the evaporator without passing through an intermediate heater and the evaporator operates in the critical flow regime. - View Dependent Claims (8, 9, 10, 18)

11. A method for supersonic cooling, comprising:
-
flowing a fluid through a flow path, the flow path having a high pressure region and a low pressure region, the fluid flowing through the flow path with the aid of a pump; dropping the pressure of the flowing fluid at an evaporator situated at the low pressure region of the flow path, wherein the flowing fluid is fed into the evaporator by the pump without passing through an intermediate heater; and inducing a phase change of the flowing fluid at the evaporator, the evaporator operating in the critical flow regime. - View Dependent Claims (12, 13, 14, 15, 16, 17, 19)
