  1. CHE/ME 109 Heat Transfer in Electronics LECTURE 1 - INTRODUCTION

  2. PRELIMINARY INFORMATION • PRE-REQUISITE CHECK SHEET • WEB SITE IS USED TO TRANSMIT INFORMATION http://www.engr.sjsu.edu/~jennimi/Classes/CHEME109/

  3. GREENSHEET REVIEW • SCHEDULE • TEXT • TEXT IS THE BASIS FOR HOMEWORK PROBLEMS • BE CERTAIN TO REVIEW ALL EXAMPLES • CONCEPT PROBLEMS ARE MARKED WITH A C • YOU SHOULD BE ABLE TO ANSWER ALL OF THOSE • THESE PROBLEMS PROVIDE A GOOD PRE-TEST REVIEW SET

  4. GREENSHEET REVIEW • HOMEWORK • IS A SIGNIFICANT PART OF THE GRADE • FOLLOW THE FORMAT TO GET CREDIT • MAKE IT LEGIBLE • USE SIGNIFICANT FIGURES • WILL NOT BE ACCEPTED LATE

  5. HOMEWORK SOLUTIONS • COMPUTER BASED SOLUTIONS ARE ALLOWABLE • SPREADSHEET • MAKE SURE TO USE VARIABLE NAMES IN EQUATIONS - NOT CELL NUMBERS • DO NOT USE AUTOMATIC CURVE FITS OR SMOOTHING ON GRAPHS • MATLAB • MATHCAD • EES - IS AN EQUATION SOLVER THAT COMES WITH THE TEXT. THIS MAY BE USED BUT THERE WILL NOT BE ANY SEPARATE TRAINING PROVIDED IN THE CLASS • MUST BE INDIVIDUAL SOLUTIONS - COPIES ARE NOT ACCEPTABLE • SAME SOLUTION = SAME GRADE = 0

  6. OBJECTIVES FOR THIS COURSE H • A GROUP OF COURSE LEARNING OBJECTIVES (CLO’s) HAS BEEN DEVELOPED AND IS ATTACHED TO THE GREENSHEET. • IN SIMPLE TERMS, YOU SHOULD LEARN ABOUT ENERGY MANAGEMENT FOR ELECTRONIC SYSTEMS • PRIMARILY HEAT MANAGEMENT • HEAT INCREASES RESISTANCE AND DECREASES EFFICIENCY AND RELIABILITY • OVERHEATING CAN RESULT IN FAILURES

  7. OVERHEATING FACTORS

  14. OBJECTIVES FOR THIS COURSE • OTHER CONCEPTS IN THE COURSE WILL MAKE IT EASIER FOR YOU TO WORK WITH OTHER DISCIPLINES • THIS IS IMPORTANT WITH REGARD TO CONTROL SYSTEM INTERFACES AND RESPONSE TIMES • IT ALSO ALLOW AN APPRECIATION FOR HOW THE PHYSICAL COMPONENTS CAN AFFECT THE PERFORMANCE OF THE DEVICES.

  15. COURSE STRUCTURE • HOMEWORK AS A LEARNING TOOL • HOMEWORK IS COMPLETED AHEAD OF THE LECTURE • HOMEWORK SOLUTIONS ARE DISCUSSED DURING THE LECTURE TO DETERMINE AREAS THAT NEED DISCUSSION • EXAMS WILL NOT BE REPEATS OF HOMEWORK PROBLEMS • THE SAME CONCEPTS WILL BE INCLUDED, BUT THE SOLUTIONS WILL REQUIRE UNDERSTANDING THE CONCEPTS IN A NON-LINEAR FASHION • IF YOU CAN ONLY UNDERSTAND A CONCEPT IN ONE APPLICATION, THEN YOU WILL NOT RECEIVE A HIGH TEST SCORE
