Abstract

In the design of electronic circuits, stands out the power stage, which is responsible of increasing the signal characteristics, as current and voltage, for an appropriate performance of the device to fabricate. However, this stage is composed of elements like transistors, which may have a low performance, due to the undesired temperature increase, as a result of reaching the desired power. To mitigate the loss of power and with it, the temperature rise, the management of heat sink is proposed, in order to keep the work of the power stage at a stable level and avoid thermal fractures within the circuit. This manuscript presents the obtained results of the thermal analysis in finite elements of the heat sink with fins in the form of a Cesaro curve, for power semiconductors, which evidence the increase in the heat flow, with respect to the commercial ones and so, facilitate the heat evacuation for conditioning the voltage and/or current.

基于cesaro曲线的功率半导体无源散热器设计

在电子电路的设计中，突出的是功率级，它负责增加信号的特性，如电流和电压，以使器件具有适当的性能。然而，这一阶段是由晶体管等元件组成的，由于达到所需功率的结果是不希望的温度升高，这些元件可能具有较低的性能。为了减轻功率损耗和温度升高，提出了散热器的管理，以保持功率级的工作在一个稳定的水平，避免电路内的热断裂。本文以Cesaro曲线的形式介绍了功率半导体带翅片散热器的有限元热分析结果，证明了相对于商用散热器的热流增加，从而有利于调节电压和/或电流的热排出。

期刊介绍： Revista Facultad de Ingenieria started in 1984 and is a publication of the School of Engineering at the University of Antioquia. The main objective of the journal is to promote and stimulate the publishing of national and international scientific research results. The journal publishes original articles, resulting from scientific research, experimental and or simulation studies in engineering sciences, technology, and similar disciplines (Electronics, Telecommunications, Bioengineering, Biotechnology, Electrical, Computer Science, Mechanical, Chemical, Environmental, Materials, Sanitary, Civil and Industrial Engineering). In exceptional cases, the journal will publish insightful articles related to current important subjects, or revision articles representing a significant contribution to the contextualization of the state of the art in a known relevant topic. Case reports will only be published when those cases are related to studies in which the validity of a methodology is being proven for the first time, or when a significant contribution to the knowledge of an unexplored system can be proven. All published articles have undergone a peer review process, carried out by experts recognized for their knowledge and contributions to the relevant field. To adapt the Journal to international standards and to promote the visibility of the published articles; and therefore, to have a greater impact in the global academic community, after November 1st 2013, the journal will accept only manuscripts written in English for reviewing and publication. Revista Facultad de Ingeniería –redin is entirely financed by University of Antioquia Since 2015, every article accepted for publication in the journal is assigned a DOI number.
