Antecedentes de la invención Background of the invention
Los intercambiadores de microcanales de aluminio soldado. formados principalmente por un tubo extruido de aluminio y aletas corrugadas con o sin ventana, se han usado desde hace tiempo en la técnica como condensadores, radiadores y aplicaciones de aire acondicionado y refrigeración en general Este tipo de intercambiadores proporcionan una serie de ventaja~ en comparación con otros tipos de intercambiadores anteriores;: tales como un menor coste, mayor rendimiento energético, mej 0r; resistencia a la corrosión, menor peso, menor volumen y fácíl' reciclaje. The welded aluminum microchannel exchangers. Formed mainly by an extruded aluminum tube and corrugated fins with or without a window, they have long been used in the art as condensers, radiators and air conditioning and refrigeration applications in general. These types of exchangers provide a number of advantages ~ in comparison with other types of previous exchangers: such as lower cost, higher energy efficiency, better 0r; corrosion resistance, lower weight, lower volume and easy recycling.
Sin embargo, el uso de este tipo de intercambiadores como evaporadores presenta el problema de la condensación de agua en los mismos. En efecto, la humedad del aire que se hace pasar a través de un evaporador para enfriarlo suele depositarse sobre dicho evaporador por efecto de la condensación, lo que produce una serie de inconvenientes tales como pérdida de rendimiento, mayor pérdida de carga en el aire, congelación, arrastre de gotas de agua con el aire (lo que provoca salpicaduras al usuario), crecimiento de bacterias y malos olores, etc. However, the use of this type of exchangers as evaporators presents the problem of water condensation in them. In fact, the humidity of the air that is passed through an evaporator to cool it is usually deposited on said evaporator as a result of condensation, which produces a series of inconveniences such as loss of performance, greater loss of charge in the air, freezing, dragging water droplets with the air (which causes splashing of the user), growth of bacteria and odors, etc.
En la técnica anterior se han propuesto diversas soluciones para intentar evitar la condensación de agua sobre este tipo de evaporadores. Se han propuesto soluciones basadas en cambiar la orientación de los intercambiadores, de tal manera que los Various solutions have been proposed in the prior art to try to avoid water condensation on this type of evaporators. Solutions based on changing the orientation of the exchangers have been proposed, so that the

5 agua condensada permanece en las aletas. Por otro lado, esta configuracion empeorard el funcionamiento del intercambiador como condensador, lo cual seria perjudicial en aplicaciones que requieran la inversion del ciclo frigorifico, tales como por' ejemplo bombas de calor. 5 condensed water remains in the fins. On the other hand, this configuration worsens the operation of the exchanger as a capacitor, which would be detrimental in applications that require the reversal of the refrigeration cycle, such as by example heat pumps.
10 Ademds de los problemas mencionados anteriormente, los intercambiadores de microcanales presentan aim mayores dificultades para su aplicacion en la refrigeracion, ya que las temperaturas de trabajo en este caso son extremadamente bajas y se produce mas rdpidamente una acumulacion de hielo. Est4 In addition to the problems mentioned above, the microchannel exchangers present major targets difficulties for its application in refrigeration, since the working temperatures in this case are extremely low and an accumulation of ice occurs more quickly.

15 Elevaporador/condensador tal como se observa en la figura 1 comprende cuatro tubos 10 por los que circula un fluidt) ref rigerante y conectados entre si por una serie de microcanales multipuerto 12 (visibles en la figura 3). Estos microcanales multipuerto 12 se encuentran dentro de una configuracioh 15 Elevator / condenser as seen in figure 1 it comprises four tubes 10 through which a fluidt circulates) ref governing and connected to each other by a series of microchannels multiport 12 (visible in figure 3). These microchannels multiport 12 are within a configuration
20 aplanada. El evaporador/condensador comprende ademds una multitud dg aletas 14 dispuestas en la misma direccion que los tubos 10 (es decir, en la posicion de uso mostrada en las figuras, en la direccion vertical) y que son transversales a los microcanales 20 flattened. The evaporator / condenser also comprises a multitude of dg fins 14 arranged in the same direction as the tubes 10 (is that is, in the position of use shown in the figures, in the vertical direction) and that are transverse to the microchannels
25 multipuerto 12. Las aletas 14 se unen a los microcanales multipuerto 12, por ejemplo, mediante soldadura. De este modo, la disposicion en vertical de las aletas 14 en la posicion de uso del evaporador/condensador facilita el drenaje de agua condensada sobre las mismas. Puede observarse ademds que cada 25 multiport 12. The fins 14 join the microchannels multiport 12, for example, by welding. In this way, the vertical arrangement of the fins 14 in the position of use of evaporator / condenser facilitates water drainage condensed on them. It can also be seen that each

In this figure you can see, in addition to all the elements described above, a series of eyelashes 18 arranged on fins 14. These eyelashes 18 define the passage between the fins 14. It is easy, depending of the refrigeration application planned for the
10 evaporador/condensador de la invencion, variar la distancia entre dichas aletas 14 en funcion de la geometria de lab pestailas 18. De este modo puede reducirse la distancia entre las aletas 14 para aplicaciones de aire acondicionado (temperaturae >0°C) y aumentarse para aplicaciones de refrigeracion 10 evaporator / condenser of the invention, vary the distance between said fins 14 depending on the lab geometry eyelashes 18. This can reduce the distance between the fins 14 for air conditioning applications (temperature > 0 ° C) and be increased for refrigeration applications
15 (temperaturas <0°C) 15 (temperatures <0 ° C)
Tal como tambien se observa en la figura 3, los microcanales multipuerto 12 de cada par de tubos 10 estan dispuestos a la misma altura, de modo que el flujo de aire indicado por una flecha en la figura 3 pasa entre los microcanales multipuerto 12 As can also be seen in figure 3, the microchannels multiport 12 of each pair of tubes 10 are arranged at the same height, so that the air flow indicated by a arrow in figure 3 passes between multiport microchannels 12
20 produciendose el intercambio de temperatura con el fluido' refrigerante que circula por su interior. El cambio de' temperatura del aire provoca que se condensen gotas 16 de agua sobre las aletas 14 que, por efecto de la gravedad gracias a la disposicion vertical de las mismas, drenan facilmente hacia 20 taking place the exchange of temperature with the fluid ' refrigerant circulating inside. The change of' air temperature causes 16 drops of water to condense on the fins 14 which, due to the effect of gravity thanks to the vertical arrangement of them, drain easily towards

The main difference with respect to the first embodiment
30 descrita anteriormente se encuentra en el hecho de que los microcanales multipuerto 12 de cada uno de los pares de tubos 10 estan dispuestos a alturas alternadas. De este modo se aumenta la turbulencia del aire que pasa entre dichos microcanales multipuerto 12 aumentando asi el intercambio de calor con el 30 described above is found in the fact that the multiport microchannels 12 of each of the pairs of tubes 10 They are arranged at alternate heights. This increases the turbulence of the air that passes between said microchannels multiport 12 thus increasing heat exchange with the
35 fluido refrigerante que circula por el interior de los mismos. 35 refrigerant fluid circulating inside them.
