    Modelación de tubos de calor tipo sifón mediante el uso de un software computacional para disipar calor en el procesador de una computadora de escritorio

    His first studies of heat pipes began in 1944, his first applications were in satellites with the aim of maintaining a uniform and distributed temperature throughout the structure, then he focused more on the branch of electronics. The investigations were carried out in heat pipes that are elements of great thermal conductivity, their structure is completely closed, they state; of an evaporator, an adiabatic section and a condenser section were used; various working fluids, distilled water having a range of 30 to 200 degrees centigrade, ammonia -60 to 100 degrees centigrade, sodium 600 to 1200 degrees centigrade, mercury 250 to 650 degrees centigrade, methanol 10 to 104 degrees centigrade. Round copper, aluminum and stainless-steel heat pipes were used that are designed between 0.6 x 0.6 mm in their cross section and their length can vary between 25 and 100 mm according to their use, inside they are formed without a wick or with an enveloping fine mesh wick, sintered powder metal, axial groove and among others. The operation was applied to the evaporator that leads through the wick and the tube that vaporizes the working fluid, the pressure of the vapor is driven towards the condenser where the vapor is condensed, the capillary pressure created in the wick pumps the condensed liquid towards behind this process is continuous as long as there is capillary pressure.

    Análisis del material de la mecha en los tubos de calor y su influencia sobre la temperatura en la zona de condensado
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Diseño Mecánico, 2014) Escobar Luna, Luis Eduardo; Moreno Romero, Telmo Jesús Gerardo
    Los tubos de calor son elementos altamente conductivos, en su interior están conformados por diferentes tipos y formas de materiales, comúnmente llamados “mecha”, por el cual se conduce el fluido de trabajo. Una de las características fundamentales de este tipo de intercambiador de calor, es que en su interior se realiza el vacío, lo que imposibilita que se formen condensados no deseable que afectan a las propiedades del fluido de trabajo y por tal motivo el flujo de transferencia de calor se ve afectada; adicionalmente pueden ser usados en sistemas donde la ingravidez este presente. La búsqueda de procesos alternativos que mejoren la eficiencia térmica y que consecuentemente produzcan una huella ambiental menor han motivado este estudio investigativo.
