The project of Electronic Cooling System was presented for the Optimization of Thermal System class in April 2009.

1. Design and Evaluation of Electronic Cooling Systems By SuabsakulGururatana Prashant Ghadge Serkan Ongun Jatin Lad Mechanical Engineering Department Lamar University

2. Introduction Problem Statement: A piece of electronic equipment dissipates a total of 400 W. Its base dimension must not exceed 40 cm x 30 cm, and high must be less than 15 cm. Six boards are employed to mount the component. The temp. should not go beyond 120 ºC anywhere in the system. The Electronic Equipment

4. Comparative study between two systems.

5. Consideration of Design and Optimization criteria.

7. Model - Forced Air-Cooled System Forced Air-Cooled System

8. Model- Refrigeration System Refrigeration System

10. Fluent software – Simulation

11. Temperature of the board fixed to 120F

12. Temperature of the incoming air 77F

13. Velocity inlet is changed for several trials to get the rate of heat transfer (Q) = 400W

14. We get the performance relation.

16. Analysis- Refrigeration System Temperature distribution over equipment for Refrigeration System

17. Optimization

18. Forced Air-Cooled System Q-V diagram for forced air cooled system

20. Constraint Q = AV

21. Total Q = 0.86 m3/s

22. For single fan Q = 0.29 m3/s

25. Constraint Q = AV

26. Total Q = 0.27 m3/s

27. For single fan Q = 0.09 m3/s

30. Constraint Q = AV

31. Total Q = 0.83 m3/s

32. For single fan Q = 0.27 m3/s,

35. Constraint Q = AV

36. Total Q = 0.84 m3/s

37. For single fan Q = 0.28m3/s,

40. Unconstraint

41. Therefore, t = 11.03° C

43. Better system – Forced Air Cooled

44. Special purpose – Refrigeration systems
