Abstract

A supersonic cooling system operates by pumping liquid. Because supersonic cooling system pumps liquid, the compression system does not require the use a condenser. Compression system utilizes a compression wave. The evaporator of 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.

Claims (24)

1. A supersonic cooling system, the system comprising:

a pump that maintains a circulatory fluid flow through a flow path; and

an evaporator that operates in the critical flow regime and generates a compression wave that shocks the maintained fluid flow thereby changing the pressure of the maintained fluid flow and exchanging heat introduced into the circulatory fluid flow, and wherein no heat is added to the circulatory fluid flow before the circulatory fluid flow passes through the evaporator.

2. The supersonic cooling system of claim 1 , wherein the pump and evaporator are located within a housing.

3. The supersonic cooling system of claim 2 , wherein the external surface of the housing effectuates forced convection and further exchanges heat introduced into the compression system.

4. The supersonic cooling system of claim 1 , wherein the pump maintains the circulatory fluid using vortex flow rings.

5. The supersonic cooling system of claim 4 , wherein the pump progressively introduces energy to the vortex flow rings that corresponds to energy being lost through dissipation.

6. The supersonic cooling system of claim 1 , wherein the pump raises the pressure of the circulatory fluid flow from approximately 20 PSI to approximately 100 PSI.

7. The supersonic cooling system of claim 1 , wherein the pump raises the pressure of the circulatory fluid flow to more than 100 PSI.

8. The supersonic cooling system of claim 2 , further comprising a pump inlet that introduces a cooling liquid maintained within the housing to the pump, and wherein the cooling liquid is a part of the circulatory fluid flow.

9. The supersonic cooling system of claim 8 , wherein the evaporator further induces a pressure drop in the cooling liquid to approximately 5.5 PSI, and a corresponding phase change that results in a low temperature of the cooling liquid.

10. The supersonic cooling system of claim 9 , wherein the cooling liquid is water.

11. A cooling method, the method comprising:

establishing a compression wave in a compressible fluid by passing the compressible fluid from a high pressure region to a low pressure region, wherein the velocity of the fluid is greater than or equal to the speed of sound in the compressible fluid, and wherein no heat is added to the compressible fluid before the compressible fluid passes through an evaporator; and

exchanging heat introduced into a fluid flow of the compressible fluid during a phase change of the compressible fluid.

12. The method of claim 11 , further comprising exchanging heat through convection by way of one or more surfaces in contact with a flow of the compressible fluid.

13. The method of claim 11 , wherein the phase change corresponds to a change in pressure of the compressible fluid.

14. The method of claim 13 , wherein a pressure change within a fluid flow of the compressible liquid occurs within a range of approximately 20 PSI to approximately 100 PSI.

15. The method of claim 13 , wherein a pressure change within a fluid flow of the compressible liquid involves a change to an excess of 100 PSI.

16. The method of claim 13 , wherein a pressure change within a fluid flow of the compressible liquid involves a change to less than 20 PSI.

17. The supersonic cooling system of claim 1 , wherein the pump raises the pressure of the circulatory fluid flow from approximately 20 PSI to approximately 300 PSI.

18. The supersonic cooling system of claim 1 , wherein the pump raises the pressure of the circulatory fluid flow from approximately 20 PSI to approximately 500 PSI.

19. The method of claim 13 , wherein a pressure change within a fluid flow of the compressible liquid occurs within a range of approximately 20 PSI to approximately 300 PSI.

20. The method of claim 13 , wherein a pressure change within a fluid flow of the compressible liquid occurs within a range of approximately 20 PSI to approximately 500 PSI.
