Development of water-cooled heat sink for high-power IGBT inverter

In view of the cooling of Insulated-gate bipolar transistors (IGBTs) in the parallel DC boost chopper, this paper presents a method to calculate the power loss of IGBTs. It involves functions of equivalent heat circuit of liquid cooling system based on the similarity theory, and the design of the parameters in the cooling system for DC boost chopper. It solves the problems of parameters designing of liquid-cooled heat sink. Taking the cooling system of IGBTs as an example, the experiment shows that the cooling system based on this method has excellent performances in the worksite, and the method is practical and effective.

This paper focuses on three level high-power IGBT converter protection against high humidity and high temperature effects. The influences of high temperature and high humidity on the system performances were analyzed and optimized. The protection and cooling systems were designed. The proposed water-cooling type heat sink was designed. Furthermore, the selection of materials for the proposed enclosed container and coating were optimized to achieve high insulation thermal resistance and high humidity insulation. The thermal and fluid analyses emphasized the relevant use of the proposed water-cooling system and improved the performances of the converter remarkably. The proposed method for protecting the converter against high humidity needs to be tested at high humidity environment, to insure its effectiveness.

“…The efficient function of a heat sink depends on a rapid transfer of thermal energy from an object to the heat sink [10]. This can be achieved through an application of forced convection [4,9,[11][12][13][14] or natural convection [8,[15][16][17].…”

El objetivo principal de esta investigación es estudiar y analizar la gestión de la tecnología y la innovación a través de la fabricación de un disipador térmico para transistores de potencia IGBT que se adapten a un convertidor CD/CD. Este trabajo consta de cuatro etapas: planificación, diseño, modelado y fabricación. Se asume que la fabricación de un producto innovador requiere garantizar la satisfacción del cliente, ya que se definieron criterios funcionales (requisitos) como en disminuir la temperatura a menos de 50 ° C, la disipación de calor se realiza por convección natural o convección forzada. Criterios no funcionales, como fácil transporte con un peso inferior a 2,5 kg. dimensiones inferiores a 0,32 m de largo, 0,217 m de ancho y 0,09 cm de alto. Además, el material acondicionado es cobre o aluminio o el uso de ambos. Para lograrlo, se utilizó la metodología de Pugh.
