SISTEMA DE VENTILACIÓN PARA ARMARIOS DE EQUIPOS VENTILATION SYSTEM FOR EQUIPMENT CABINETS
INFORMÁTICOSCOMPUTERS
Sector de la técnicaTechnical sector
La presente invención está relacionada con la disposición de equipamientos informáticos en armarios de organización, proponiendo un sistema de ventilación que permite eliminar con una gran eficacia el calor que genera el funcionamiento de los aparatos informáticos dentro de los armarios en los que se disponen.The present invention is related to the provision of computer equipment in organizational cabinets, proposing a ventilation system that allows to eliminate with great efficiency the heat generated by the operation of computer equipment within the cabinets in which they are arranged.
Estado de la técnicaState of the art
Es conocida la inclusión de los equipos informáticos en armarios donde la disposición de los aparatos y los cableados de conexión se organizan de una manera que favorece el montaje y reduce la interferencia en el entorno.It is known to include computer equipment in cabinets where the arrangement of the devices and the connection wiring are organized in a way that favors assembly and reduces interference in the environment.
Sin embargo, el gran número de transacciones que tienen que desarrollar normalmente los equipos informáticos asi dispuestos y la densidad de los aparatos componentes de los mismos, hace que se genere y concentre una gran cantidad de calor en el interior de los armarios contenedores, siendo necesario eliminar ese calor para asegurar el funcionamiento correcto de los equipos y evitar su deterioro.However, the large number of transactions normally carried out by the computer equipment so arranged and the density of the component devices thereof, causes a large amount of heat to be generated and concentrated inside the container cabinets, being necessary Eliminate that heat to ensure the proper functioning of the equipment and prevent its deterioration.
Los sistemas de ventilación que se vienen aplicando en dichos armarios contenedores de los equipos informáticos, funcionan normalmente introduciendo un flujo de aire por la parte inferior, habitualmente desde un suelo técnico, y empujando dicho flujo hacia arriba por la parte frontal, entre los equipos alojados y la puerta del armario, desde donde los propios sistemas de refrigeración de los equipos lo aspiran para que circule a través de ellos refrigerándolos, expulsándose el aire caliente por la parte posterior, en donde desde una salida superior se aspira mediante extractores.The ventilation systems that are being applied in said container cabinets of the computer equipment, normally operate by introducing an air flow through the bottom, usually from a technical floor, and pushing said flow up the front, between the housed equipment and the cabinet door, from where the equipment's own cooling systems aspirate it to circulate through them, cooling them, expelling hot air from the back, where from an upper outlet it is aspirated by extractors.
Dicho sistema tiene el inconveniente de que el aire tiene mucha velocidad y baja temperatura en la parte inferior del armario, pero esa velocidad y temperatura se pierden en la parte alta, de manera que los equipos situados en esta parte alta no se refrigeran con la misma efectividad que los de la parte baja .Said system has the disadvantage that the air has a lot of speed and low temperature in the lower part of the cabinet, but that speed and temperature are lost in the high part, so that the equipment located in this high part is not cooled with the same effectiveness than those in the lower part.
Y por otra parte, los extractores de evacuación del aire caliente tienen que succionar el aire desde la parte superior del armario, por lo que su rendimiento es difícil, porque el poder de succión disminuye desde la parte alta hasta la parte baja.And on the other hand, the exhaust fans of the hot air have to suck the air from the top of the cabinet, so that its performance is difficult, because the suction power decreases from the top to the bottom.
Existen soluciones en las que el flujo de aire de refrigeración asciende por el interior de la puerta frontal del armario, la cual tiene unas aberturas repartidas por su cara interior para la salida del aire, pero estas salidas no tienen regulación que permita adaptar la salida del aire según se precise en cada zona, siendo además la puerta ciega, de forma que no permite ver las luces indicadoras del funcionamiento de los aparatos instalados en el interior del armario, y cuando se abre la puerta el sistema deja de funcionar.There are solutions in which the flow of cooling air rises through the inside of the front door of the cabinet, which has openings distributed on its inner face for the air outlet, but these outlets have no regulation to adapt the outlet of the air as required in each area, the door being also blind, so that it does not allow to see the indicator lights of the operation of the devices installed inside the cabinet, and when the door is opened the system stops working.
Objeto de la invención Según la invención se propone un sistema de ventilación con unas características constructivas y funcionales que le hacen de fácil aplicación en los armarios contenedores de equipos informáticos, en donde permite una gran efectividad para la refrigeración de los equipos, sin los inconvenientes de las soluciones convencionales .Object of the invention According to the invention, a ventilation system is proposed with constructive and functional characteristics that make it easy to apply in the computer equipment container cabinets, where it allows great effectiveness for the refrigeration of the equipment, without the inconveniences of conventional solutions.
Este sistema objeto de la invención consta de un módulo de impulsión que se dispone en la parte inferior para aspirar aire frió desde un suelo técnico, partiendo de dicho módulo dos conductos verticales que se extienden por los laterales de la parte frontal interior del armario, los cuales conductos poseen una distribución de salidas provistas con difusores regulables en orientación y apertura, mientras que en la parte posterior se establece una distribución de salidas provistas con ventiladores de aspiración, incorporándose dichas salidas en la puerta posterior del armario, por el interior de la cual se determina un conducto de evacuación del aire hasta una salida superior.This system object of the invention consists of a drive module that is arranged in the lower part to draw cold air from a technical floor, starting from said module two vertical ducts that extend along the sides of the inner front part of the cabinet, the which ducts have a distribution of exits provided with adjustable diffusers in orientation and opening, while in the rear part a distribution of exits provided with suction fans is established, said exits being incorporated in the rear door of the cabinet, through which an air evacuation duct is determined to a higher outlet.
Este sistema permite tener aire frió en cualquier altura del armario a la misma temperatura que se introduce por la parte inferior, merced a la distribución vertical de las salidas del aire definidas en los conductos que ascienden desde el módulo de impulsión, siendo impulsado dicho aire en horizontal desde la parte delantera hacia la parte posterior a través de los alojamientos en los que se encuentran dispuestos los aparatos alojados en el armario, con lo cual el aire frió llega de una manera uniforme a los aparatos, los cuales pueden aspirarlo fácilmente, lográndose una refrigeración muy eficaz. Mediante los difusores regulables de las salidas, se puede graduar además el flujo de aire saliente en cada altura, permitiendo adaptar la refrigeración en función de la ocupación del armario, de forma que en las zonas que hay más aparatos o aparatos que generan mayor cantidad de calor, se puede establecer una salida de mayor cantidad de aire, pudiendo incluso anularse la salida de aire en las zonas que no haya instalados aparatos, con lo que se aprovecha de una forma más eficiente en la refrigeración el aire que se hace circular por el armario.This system allows to have cold air at any height of the cabinet at the same temperature that is introduced from the bottom, thanks to the vertical distribution of the air vents defined in the ducts that ascend from the drive module, said air being driven in horizontal from the front to the back through the housings in which the devices housed in the closet are arranged, whereby the cold air uniformly reaches the appliances, which can easily aspirate it, achieving a Very effective cooling By means of the adjustable diffusers of the exits, the flow of outgoing air at each height can also be adjusted, allowing to adapt the cooling according to the occupation of the cabinet, so that in the areas that there are more devices or devices that generate a greater amount of heat, an outlet with a greater amount of air can be established, and the air outlet can even be canceled in areas where there are no devices installed, so that the air that circulates through the air can be used more efficiently in cooling wardrobe.
Con este sistema la distribución del aire de refrigeración es totalmente independiente de la puerta frontal del armario, la cual puede ser acristalada para dejar ver los indicadores del funcionamiento de los aparatos instalados en el interior; y el sistema puede seguir funcionando aunque la puerta se abra, de modo que la refrigeración de los aparatos se mantiene constante.With this system the distribution of the cooling air is completely independent of the front door of the cabinet, which can be glazed to show the indicators of the operation of the devices installed inside; and the system can continue to operate even if the door is opened, so that the refrigeration of the appliances remains constant.
Por todo ello, el sistema de la invención resulta de unas características ciertamente ventajosas, adquiriendo vida propia y carácter preferente respecto de los sistemas de refrigeración convencionales de la misma aplicación.Therefore, the system of the invention results in certain advantageous characteristics, acquiring its own life and preferential character with respect to conventional refrigeration systems of the same application.

Descripción detallada de la invenciónDetailed description of the invention
El objeto de la invención se refiere a un sistema de ventilación destinado para eliminar el calor que se genera en el interior de los armarios de organización de equipos informáticos, para mejorar las condiciones de funcionamiento de los aparatos componentes de los equipos, alargar la vida útil de los mismos y mejorar la eficiencia del consumo energético.The object of the invention relates to a ventilation system designed to eliminate the heat generated inside the organizational cabinets of computer equipment, to improve the operating conditions of the equipment components of the equipment, extend their useful life and improve the efficiency of energy consumption.
El sistema comprende un módulo (1) de impulsión de aire, formado por un cuerpo (1.1) que se dispone en la parte inferior del armario (2) de aplicación, en relación con una entrada (3) de aspiración de aire desde por ejemplo un suelo técnico por el que circula el aire de refrigeración del local de instalación.The system comprises an air supply module (1), formed by a body (1.1) that is arranged in the lower part of the application cabinet (2), in relation to an air intake (3) for example from a technical floor through which the cooling air of the installation room circulates.
En el cuerpo (1.1) se aloja un ventilador (4) que hace la función de impulsor del aire, saliendo desde dicho cuerpo (1.1) unos conductos verticales (1.2) que se extienden por los laterales de la parte delantera interior del armario (2), los cuales conductos (1.2) se hallan provistos con un distribución de salidas (5) orientadas hacia la zona media de la mencionada parte delantera del interior del armario (2) .In the body (1.1) there is a fan (4) that acts as an air impeller, leaving from said body (1.1) vertical ducts (1.2) extending along the sides of the inside front part of the cabinet (2 ), which ducts (1.2) are provided with a distribution of outlets (5) oriented towards the middle area of said front part of the interior of the cabinet (2).
Dichas salidas (5) de los conductos verticales (1.2) se hallan provistas con difusores de aire (6) regulables en orientación y apertura, de manera que en cada una de las salidas (5) se puede graduar selectivamente el paso de la salida de aire y la dirección de proyección del aire saliente, pudiendo incluso anularse por completo el paso de aire por las salidas (5) que corresponden a zonas del armario (2) en las que no hay instalados aparatos que haya que refrigerar.Said outlets (5) of the vertical ducts (1.2) are provided with adjustable air diffusers (6) in orientation and opening, so that in each of the outlets (5) the passage of the outlet of air and the projection direction of the outgoing air, the air passage may even be completely canceled by the outlets (5) corresponding to areas of the cabinet (2) in which there are no devices to be cooled.
El sistema comprende además una distribución de salidas (7) de extracción del aire caliente, definidas en la parte posterior del recinto interior del armario, estando provistas estas salidas (7) con ventiladores de absorción para forzar el paso del aire a través de ellas .The system also comprises a distribution of hot air extraction outlets (7), defined on the back of the interior cabinet enclosure, these outlets (7) being provided with absorption fans to force the passage of air through them.
Dichas salidas (7) de extracción se prevén definidas en la puerta (8) posterior del armario (2), estructurándose dicha puerta (8) con una formación hueca que determina por el interior un conducto de circulación del aire hasta una salida (9) de evacuación en la parte superior.Said extraction outlets (7) are provided defined in the rear door (8) of the cabinet (2), said door (8) being structured with a hollow formation that determines inside the air circulation duct to an outlet (9) of evacuation at the top.
Con ello asi, el ventilador (4) del cuerpo (1.1) aspira el aire frió por la entrada (3) y lo impulsa por los conductos verticales (1.2), desde donde el aire se proyecta por las salidas (5) al interior del armarioThus, the fan (4) of the body (1.1) sucks the cold air through the inlet (3) and drives it through the vertical ducts (1.2), from which the air is projected through the outlets (5) into the interior of the wardrobe
(2) .(2) .
De este modo el aire frió sale a la misma temperatura fria en toda la altura, proyectándose horizontalmente a través de los alojamientos (10) en los que se encuentran los aparatos a refrigerar, desde la parte delantera hacia la parte posterior del armario (2), con lo cual el aire frió pasa uniformemente por todos los alojamientos (10), en donde incide directamente sobre los aparatos instalados, los cuales pueden aspirar fácilmente dicho aire frió mediante sus propios sistemas de refrigeración, consiguiéndose asi una refrigeración muy eficaz de todos los aparatos.In this way the cold air comes out at the same cold temperature throughout the height, projecting horizontally through the housings (10) in which the appliances to be cooled are located, from the front to the back of the cabinet (2) , whereby the cold air passes uniformly through all the housings (10), where it directly affects the installed devices, which can easily aspirate said cold air through their own cooling systems, thus achieving very efficient cooling of all appliances
El aire que pasa por los aparatos produciendo la refrigeración de los mismos, circula hasta la parte posterior del armario (2), en donde es aspirado a través de las salidas (7) por la acción de los ventiladores de éstas, de manera que el aire caliente que pasa por dichas salidas (7) circula por el interior de la puerta posterior (8) hasta la salida superior (9) de evacuación, por la que sale al exterior.The air that passes through the devices producing their cooling, circulates to the back of the cabinet (2), where it is sucked through the outlets (7) by the action of the fans of these, so that the hot air passing through said outlets (7) circulates inside from the rear door (8) to the upper exit (9) of evacuation, through which it goes outside.
El aire de refrigeración circula por lo tanto de una manera forzada por todo el interior del armario (2), circulando el aire frió, como se observa en la figura 9, de una manera uniforme por todos los alojamientos (10) donde se hallan los aparatos a refrigerar, y en la parte posterior el aire caliente es aspirado también de una manera uniforme a través de las salidas (7), para su evacuación, de manera que se evitan concentraciones de aire caliente que puedan perjudicar a la refrigeración, asi como interferencias del aire caliente con el aire frió que puedan dificultar la circulación de paso del aire frió por los alojamientos (10) donde se hallan los aparatos a refrigerar; pudiendo determinarse un sincronismo entre la impulsión frontal y la extracción trasera, controlado de manera electrónica, para establecer diferentes curvas de trabajo.The cooling air therefore circulates in a forced manner throughout the interior of the cabinet (2), the cold air circulating, as seen in Figure 9, in a uniform manner through all the housings (10) where the appliances to be cooled, and in the back the hot air is also sucked in a uniform way through the outlets (7), for its evacuation, so that concentrations of hot air that can damage the refrigeration are avoided, as well as interferences of hot air with cold air that may hinder the circulation of cold air through the housings (10) where the appliances to be cooled are located; being able to determine a synchronism between the front drive and the rear extraction, electronically controlled, to establish different work curves.
El sistema de refrigeración resulta asi totalmente independiente de la puerta frontal (11) del armario (2), de manera que esta puerta (11) puede abrirse sin que se interrumpa el funcionamiento del sistema, y además, la estructura de dicha puerta (11) puede ser acristalada, con transparencia para permitir ver desde fuera los indicadores del funcionamiento de los aparatos del interior. The cooling system is thus completely independent of the front door (11) of the cabinet (2), so that this door (11) can be opened without interrupting the operation of the system, and in addition, the structure of said door (11 ) It can be glazed, with transparency to allow to see from outside the indicators of the operation of the interior appliances.
