碩士 / 大同大學 / 機械工程學系(所) / 103 / In recent years, with the advent of technology, most portable electronic goods or even larger volume of other 3C products are made in conjunction with the concept of environmental protection. In order to make the most beautiful, highest performance products with minimized material. While manufacturing the products, heat dissipation has been a very important issue. The temperature of the product will get higher when you use it for a long time. The effectiveness of the product is likely to be lower. So the research continued to be concerned for everyone.
The purpose of this thesis is to figure out the locations of heat fins in the liquid cooling system based on the velocity distributions, the temperature distributions and the direction of liquid cooling flow.
Placing strategies are designed focusing on two factors, pressure differences and quantity of pipes. We use different total pressure between the first part and the second part. The third part in the case of the first two parts of the same volume, increasing the number of heat pipe into four as a group. To compare three methods of heat dissipation efficiency ,we could find out which is the best.
Each section is placed in the best location, the highest average velocity , and with the maximum of the quantity of pipes that we placed one by one according to the highest velocity. We found that the optimal design needs 276 simulations, but the other two strategies are less than 23 times. The difference in the cooling performance between these three part is about 10%.
