For a first try I used 2 copper canals (3mmx10mm) with a source term (fitting to the power dissipation through the current with J=40A\/mm&sup2; and a filling factor of 0.6) and a cooling canal (2,4mmx10mm) in between. The length of the system is 170mm.<\/p>\n<p>For the cooling fluid I took an oil-like fluid with a starting temperature of 120&deg;=393.15K. I used different velocities from 1 m\/s to 5m\/s in the cooling canal.<\/p>\n<p>The result is, that the copper has a difference of temperatures in those 170mm of about 3,7 K with 1m\/s and about 1,8K with v=2m\/s. The fluid has differences in temperature of 3K with 1m\/s and 1,4K with 2m\/s .<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/O7XYKWOWA6KT\/initial-7-teil-6xcu3-fluid2-4-v1-png.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/O7XYKWOWA6KT\/initial-7-teil-6xcu3-fluid2-4-v1-png.png\" alt=\"Initial_7_Teil_6xCu3_Fluid2.4_v1.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-50114","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["22357"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["???t"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["204"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["50114"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","183585"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["134108"],"_bbp_last_active_id":["134108"],"_bbp_last_active_time":["2020-11-25 14:22:04"]},"test":"yakumo"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50114","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50114\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=50114"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
