It not only has the ability to regulate the temperature of electronic equipment, but also prevents the computer processor from overheating. Traditionally, radiators are manufactured using techniques such as casting, welding, and metal extrusion, and products can only make a compromise between manufacturing limitations and equipment performance. Based on this, the 18th Organizing Committee of the American Society for Thermodynamics of Electronic Systems launched a student radiator design challenge based on new technologies in additive manufacturing, and received GE sponsorship. In this issue, we will look at the outstanding designs of this competition.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-93966 size-full\" title=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" src=\"https:\/\/facfox.com\/wp-content\/uploads\/2020\/04\/20200411_5e91285ff11d0-1.jpg\" alt=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" width=\"800\" height=\"381\"   style=\"display:none\"><\/p>\n<p>The organizing committee finally selected five teams from 21 participating teams all over the world to enter the finals. They were Arizona State University, Purdue University, University of Maryland, Pennsylvania State University, and Trinity College Dublin. The new 3D printed metal heat sink they designed can effectively cool electronic equipment.<\/p>\n<p>The design of the Arizona State University team focused on increasing the surface area of the heat sink so that the hot air from the electrical components can flow without affecting its efficiency, which is a common design limitation in traditional manufacturing. They used engineering concepts to propose various methods to take full advantage of their newly discovered design freedom and maximize efficiency, and finally adopted a design that better mixes and generates turbulence when air flows to enhance heat transfer. The design freedom of this product when applying additive manufacturing technology is huge.<\/p>\n<figure id=\"attachment_93967\" aria-describedby=\"caption-attachment-93967\" style=\"width: 850px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-93967 size-full\" title=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" src=\"https:\/\/facfox.com\/wp-content\/uploads\/2020\/04\/20200411_5e912860a4214-1.jpg\" alt=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" width=\"850\" height=\"425\" \/><figcaption id=\"caption-attachment-93967\" class=\"wp-caption-text\">The design work of the Arizona State University team<\/figcaption><\/figure>\n<figure id=\"attachment_93968\" aria-describedby=\"caption-attachment-93968\" style=\"width: 850px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-93968 size-full\" title=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" src=\"https:\/\/facfox.com\/wp-content\/uploads\/2020\/04\/20200411_5e912861bb7b2-1.jpg\" alt=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" width=\"850\" height=\"425\" \/><figcaption id=\"caption-attachment-93968\" class=\"wp-caption-text\">Design works of Trinity College Dublin<\/figcaption><\/figure>\n<p>The Purdue University team uses topology optimization to find the best material distribution for a given radiator design size. The 3D printed radiator has a gently inclined &#8220;L&#8221; shape on one side and a convex &#8220;d&#8221; shape on the other side, which allows the airflow to recirculate and recirculate, thereby staying on the radiator for more time. Serdar Ozguc, a PhD student in the team \u2019s Cooling Technology Research Center, said: \u201cToday\u2019s electronic components are facing huge heat dissipation challenges. Computers and phones are getting smaller and smaller, but they consume more and more power. The heat generated by these CPUs can affect performance The safe and effective distribution can ensure the normal operation of the product. The results of topology optimization are often very complex and shocking. Traditional methods are difficult to manufacture, and additive manufacturing can be easily achieved. &#8221;<\/p>\n<figure id=\"attachment_93969\" aria-describedby=\"caption-attachment-93969\" style=\"width: 640px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-93969 size-full\" title=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" src=\"https:\/\/facfox.com\/wp-content\/uploads\/2020\/04\/20200411_5e91286427a87-1.gif\" alt=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" width=\"640\" height=\"320\" \/><figcaption id=\"caption-attachment-93969\" class=\"wp-caption-text\">The design work of the Purdue University team<\/figcaption><\/figure>\n<figure id=\"attachment_93970\" aria-describedby=\"caption-attachment-93970\" style=\"width: 850px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-93970 size-full\" title=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" src=\"https:\/\/facfox.com\/wp-content\/uploads\/2020\/04\/20200411_5e91286513075-1.jpg\" alt=\"\u7531GE\u8d5e\u52a9\u7684\u589e\u6750\u5236\u9020\u8bbe\u8ba1\u6311\u6218\u8d5b\u6709\u54ea\u4e9b\u5148\u8fdb\u7ed3\u6784\" width=\"850\" height=\"425\" \/><figcaption id=\"caption-attachment-93970\" class=\"wp-caption-text\">University of Texas design works<\/figcaption><\/figure>\n<p style=\"max-width: 100%; min-height: 1em; font-family: -apple-system-font, BlinkMacSystemFont, 'Helvetica Neue', 'PingFang SC', 'Hiragino Sans GB', 'Microsoft YaHei UI', 'Microsoft YaHei', Arial, sans-serif; letter-spacing: 0.544px; white-space: normal; box-sizing: border-box !important; overflow-wrap: break-word !important;\">The lattice structure is not only lightweight, but also has a large specific surface area, which has great advantages for promoting heat exchange and chemical reactions. <span style=\"letter-spacing: 0.544px;\">The radiating fins of traditional radiators are mostly separate, and they form a whole by brazing.
