Se han planteado modelos t\u00e9rmicos de distinto orden de complejidad que han ido reduci\u00e9ndose de manera sistem\u00e1tica en busca de una mayor eficiencia. Primeramente se ha trabajado con modelos diferenciales detallados analizando las caracter\u00edsticas t\u00e9rmicas y de flujo principales y obteniendo informaci\u00f3n relevante del proceso. En un siguiente paso se ha desarrollado y ajustado un modelo zonal simplificado bas\u00e1ndose en esta informaci\u00f3n clave. El modelo simplificado caracteriza correctamente los aspectos cr\u00edticos del modelo detallado, ofreciendo resultados \u00fatiles en un lapso de tiempo muy reducido. Los resultados t\u00e9rmicos ofrecidos por sendos modelos han sido num\u00e9ricamente verificados, experimentalmente validados y completamente analizados. el modelo simplificado se ha implementado en un software propio que facilita el dise\u00f1o de transformadores de distribuci\u00f3n desde un punto de vista estrictamente t\u00e9rmico. Esta herramienta permite analizar de manera sencilla distintos tipos de configuraci\u00f3n geom\u00e9trica y condiciones de funcionamiento y obtener cu\u00e1l es la respuesta t\u00e9rmica estacionaria del dise\u00f1o planteado. Si el dise\u00f1o no supera las expectativas planteadas de cara a su homologaci\u00f3n se facilita el proceso de redise\u00f1o y optimizaci\u00f3n de sus principales par\u00e1metros, de manera semi-automatizada. Se muestra un estudio param\u00e9trico espec\u00edfico que permite valorar la importancia relativa de distintos aspectos de dise\u00f1o en la respuesta t\u00e9rmica obtenida. Toda esta informaci\u00f3n y la herramienta desarrollada resultan de gran utilidad para el dise\u00f1ador de transformadores de distribuci\u00f3n de tipo onan.  the present thesis is focused on the development of mathematical models to simulate the cooling process that takes place inside onan distribution transformers. Thermal models of different order have been set out reducing systematically their complexity to find a higher efficiency. In a first step, detailed differential models have been used to study the principal flow and thermal characteristics and to obtain relevant information of the cooling process. In a next step, a simplified zonal model has been developed and adjusted based on this key information. The simplified model adequately characterizes all the critical skills of the detailed model, obtaining practical results in a short period of time. The thermal results of both models have been numerically verified, experimentally validated and completely analyzed. the simplified model has been implemented in a software that makes easier the design process of distribution transformers from a thermal point of view. This tool permits to know which the steady thermal response of a proposed design is and allows a straightforward analysis of different kind of geometric configurations and operational conditions. The principal parameters can be redesigned or optimized in a semi-automatized way if the adopted configuration doesn\u00c2\u00bft pass the homologation requirements. A specific parametric analysis that permits the assessment of the relative importance of different design aspects on the obtained thermal response is shown. The developed tool and the obtained information are quite useful for the onan distribution transformer designers.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Modelaci\u00f3n t\u00e9rmica de la refrigeraci\u00f3n por convecci\u00f3n natural de transformadores de distribuci\u00f3n de tipo onan<\/strong>\u00ab<\/h3>\n<ul>\n<li><strong>T\u00edtulo de la tesis:<\/strong>\u00a0 Modelaci\u00f3n t\u00e9rmica de la refrigeraci\u00f3n por convecci\u00f3n natural de transformadores de distribuci\u00f3n de tipo onan <\/li>\n<li><strong>Autor:<\/strong>\u00a0 Jon Gastelurrutia Roteta <\/li>\n<li><strong>Universidad:<\/strong>\u00a0 Navarra<\/li>\n<li><strong>Fecha de lectura de la tesis:<\/strong>\u00a0 12\/12\/2011<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Direcci\u00f3n y tribunal<\/h3>\n<ul>\n<li><strong>Director de la tesis<\/strong>\n<ul>\n<li>Juan  Carlos Ramos Gonzalez<\/li>\n<\/ul>\n<\/li>\n<li><strong>Tribunal<\/strong>\n<ul>\n<li>Presidente del tribunal: jordi Vi\u00f1olas prat <\/li>\n<li>Jes\u00fas Mar\u00eda Blanco ilzarbe (vocal)<\/li>\n<li>Francisco j.
