Claims
- 1. A method comprising:(a) preparing surfaces of a heat exchanger including one or more first surfaces and one or more second surfaces, said one or more first surfaces positioned to contact a first fluid, said one or more second surfaces positioned to contact a second fluid; (b) accelerating projectiles toward at least a portion of one or both of the one or more first surfaces and the one or more second surfaces of the heat exchanger; and (c) creating pits in at least said portion at locations where the projectiles impinge the surface of the heat exchanger.
- 2. The method of claim 1, wherein the projectiles are shots and step (b) includes accelerating the shots by a shot blast machine.
- 3. The method of claim 2, wherein the heat exchanger is an evaporator.
- 4. The method of claim 3, further comprising:(d) connecting a propelling mechanism to the heat exchanger to propel a refrigerant across the one or more first surfaces.
- 5. The method of claim 4, wherein the propelling mechanism is a compressor.
- 6. The method of claim 2, wherein the heat exchanger is a condenser.
- 7. The method of claim 6, further comprising:(d) connecting a propelling mechanism to the heat exchanger to propel the first fluid across the one or more first surfaces.
- 8. The method of claim 7, wherein the propelling mechanism is a compressor.
- 9. The method of claim 7, further comprising:(e) connecting a fan to the heat exchanger to blow air across the one or more second surfaces.
- 10. The method of claim 2, wherein the heat exchanger is a cooling tower.
- 11. The method of claim 10, further comprising:(d) connecting a pump to the heat exchanger to spray a liquid within the cooling tower.
- 12. The method of claim 2, wherein the heat exchanger is a heat sink.
- 13. The method of claim 12, further comprising:(d) connecting a fan to the heat exchanger to blow air across the one or more first surfaces.
- 14. The method of claim 2, further comprising:(d) connecting a propelling mechanism to the heat exchanger to propel the first fluid across the one or more first surfaces.
- 15. The method of claim 1, further comprising:(d) connecting a propelling mechanism to the heat exchanger to propel the first fluid across the one or more first surfaces.
