EVAPORADOR PARA UN APARATO REFRIGERADOR EVAPORATOR FOR A COOLING DEVICE
La invención se refiere a un evaporador para un aparato refrigerador, en particular un aparato refrigerador doméstico, con al menos una placa y al menos un canal de medio refrigerante, a través del que durante el funcionamiento circula el medio refrigerante. La invención está orientada también a un aparato refrigerador, en particular aparato refrigerador doméstico. The invention relates to an evaporator for a refrigerating apparatus, in particular a domestic refrigerating apparatus, with at least one plate and at least one channel of cooling medium, through which the cooling medium circulates during operation. The invention is also directed to a refrigerating apparatus, in particular domestic refrigerating apparatus.
Las placas de un evaporador se conocen por el estado de la técnica. Por ejemplo se trata al respecto de una placa de al menos dos capas, estando unidas ambas capas de la placa entre sí por laminación o procedimientos similares. No obstante mediante procedimientos especiales pueden estamparse o "insuflarse” canales entre ambas capas de la placa. De esta manera puede elaborarse un modelo adecuado de canales de refrigerante, la llamada "imagen de canal" en la placa. Si se unen entre sí las capas de la placa mediante laminación, se habla también de placas Rollbond. The plates of an evaporator are known from the prior art. For example, it is about a plate with at least two layers, both layers of the plate being joined together by lamination or similar procedures. However, by special procedures, channels between both layers of the plate can be stamped or "insufflated". In this way an appropriate model of refrigerant channels, the so-called "channel image" on the plate can be developed. If the layers are joined together of the plate by lamination, it also speaks of Rollbond plates.
Por diversas razones puede ser necesario fijar sobre un evaporador un tubo, por ejemplo un tubo de protección para un sensor de temperatura o un sensor de temperatura con forma tubular. Según el estado de la técnica se fijan tales tubos mediante pegado junto con otras piezas de sujeción adicional para la fijación a una placa. También se conoce ya la utilización de grapas para atornillar el tubo a la placa. No obstante esto exige varias etapas del trabajo. For various reasons it may be necessary to fix a tube on an evaporator, for example a protection tube for a temperature sensor or a tubular shaped temperature sensor. According to the state of the art, such tubes are fixed by gluing together with other additional fasteners for fixing to a plate. The use of clips to screw the tube to the plate is also known. However, this requires several stages of work.
El documento de publicación DE 39 28 471 A1 muestra una placa de evaporador para una instalación frigorífica en la que la placa está compuesta por dos chapas unidas entre sí con canales de medio refrigerante estampados con forma de meandro y adicionalmente un canal del sensor abierto por ambos lados para alojar un sensor de termostato. Publication document DE 39 28 471 A1 shows an evaporator plate for a refrigeration installation in which the plate is composed of two plates joined together with channels of coolant stamped with meander shape and additionally a sensor channel opened by both sides to accommodate a thermostat sensor.
El documento de publicación DE 1 751 713 A1 muestra una configuración de un sensor de temperatura de un termostato que presenta un líquido de expansión. Publication document DE 1 751 713 A1 shows a configuration of a thermostat temperature sensor that has an expansion liquid.
El documento de publicación WO 2008/071731 A1 muestra un evaporador que incluye una placa inferior y una placa superior. En la placa superior está formado un canal para un medio refrigerante en forma de vapor. Publication document WO 2008/071731 A1 shows an evaporator that includes a bottom plate and a top plate. In the upper plate a channel is formed for a cooling medium in the form of steam.
La invención se ha formulado por lo tanto el objetivo de proporcionar un evaporador con una placa a la que pueda fijarse de manera sencilla y duradera un tubo. The invention has therefore been formulated with the aim of providing an evaporator with a plate to which a tube can be fixed easily and durably.
Este objetivo lo logra la invención con las características de la reivindicación 1 y de la reivindicación 2. Formas de realización preferentes de la invención se indican en las reivindicaciones secundarias 3 a 9. This objective is achieved by the invention with the features of claim 1 and claim 2. Preferred embodiments of the invention are indicated in secondary claims 3 to 9.
La placa presenta según la invención un receptáculo para posicionar el tubo, formado mediante al menos un resalte que constituye una guía longitudinal del tubo en la placa, de las que al menos hay una, a lo largo de la cual está sujeto el mismo. Mediante la guía longitudinal se fija la posición del tubo y el tubo puede oprimirse contra el resalte durante la fijación, con lo que el mismo no puede resbalar sobre la placa durante la fijación. De esta manera se facilita considerablemente la fijación del tubo a la placa. The plate according to the invention has a receptacle for positioning the tube, formed by at least one shoulder that constitutes a longitudinal guide of the tube on the plate, of which there is at least one, along which it is attached. The position of the tube is fixed by means of the longitudinal guide and the tube can be pressed against the shoulder during fixing, so that it cannot slide on the plate during fixing. In this way, the fixing of the tube to the plate is considerably facilitated.
La guía longitudinal se forma mediante al menos un canal estampado en la placa, en cuya pared del canal se apoya el tubo en dirección longitudinal, al menos por segmentos. Un tal canal puede ser parte del canal de medio refrigerante, de los que al menos hay uno, o también un canal realizado especialmente como receptáculo para posicionar el tubo. El canal puede estar estampado en la placa o bien, tal como es usual en placas Rollbond, estar "insuflado" entre dos capas de placa. El canal presenta preferentemente en dirección longitudinal, al menos por segmentos, la misma forma que el tubo que se apoya en su pared del canal, siendo preferiblemente ambos aproximadamente rectos al menos en el segmento en el que se apoyan uno en otro. The longitudinal guide is formed by at least one channel stamped on the plate, on whose channel wall the tube is supported in the longitudinal direction, at least by segments. Such a channel can be part of the cooling medium channel, of which there is at least one, or also a channel made especially as a receptacle for positioning the tube. The channel may be stamped on the plate or, as usual on Rollbond plates, be "insufflated" between two layers of plate. The channel preferably has a longitudinal direction, at least in segments, the same shape as the tube that rests on its channel wall, preferably both being approximately straight at least in the segment on which they rest on each other.
Para configurar la guía longitudinal se han ideado actualmente dos formas de realización preferentes: Según una primera forma de realización se forma la guía longitudinal mediante un canal en el que está estampada una cavidad que discurre en la dirección longitudinal del canal, en la que se apoya el tubo en dirección longitudinal al menos por segmentos. En esta forma de realización está previsto por ejemplo un canal cuya forma se corresponde con la del tubo. Este canal se configura por ejemplo primeramente como una sobreelevación longitudinal en un lado de la placa. A lo largo del grado de la sobreelevación se genera una cavidad alargada estampada. En el receptáculo así generado se aloja el tubo. In order to configure the longitudinal guide, two preferred embodiments are currently devised: According to a first embodiment, the longitudinal guide is formed by a channel in which a cavity that runs in the longitudinal direction of the channel, on which it rests, is stamped the tube in the longitudinal direction at least by segments. In this embodiment, for example, a channel is provided whose shape corresponds to that of the tube. This channel is configured, for example, first as a longitudinal elevation on one side of the plate. An elongated stamped cavity is generated along the degree of over-elevation. The tube is housed in the receptacle thus generated.
Según una segunda forma de realización se forma la guía longitudinal mediante dos canales al menos esencialmente paralelos, entre los que se apoya el tubo en dirección longitudinal al menos por segmentos. Ambos canales paralelos forman entonces preferiblemente dos sobreelevaciones que discurren aproximadamente en paralelo en un lado de la placa, apoyándose el tubo en el "valle" entre According to a second embodiment, the longitudinal guide is formed by two channels at least essentially parallel, between which the tube is supported in longitudinal direction at least by segments. Both parallel channels then preferably form two over-elevations that run approximately parallel on one side of the plate, the tube resting on the "valley" between

ambas sobreelevaciones. El tubo se apoya por tanto en la cara exterior de las paredes del canal. Ambos canales son preferiblemente paralelos entre sí, pero pueden presentar – en función de la forma y tamaño del tubo a fijar -un ángulo de hasta 10° entre sí. Ambos canales son preferiblemente rectos al menos en un segmento. Both over elevations. The tube therefore rests on the outer face of the canal walls. Both channels are preferably parallel to each other, but may have - depending on the shape and size of the tube to be fixed - an angle of up to 10 ° to each other. Both channels are preferably straight in at least one segment.
Mediante una guía longitudinal así generada puede tenderse un tubo en un lugar definido de la placa. Allí se fija el mismo preferiblemente pegado apoyado en la guía longitudinal sobre la placa, de las que al menos hay una. Esto puede realizarse por ejemplo mediante adhesivo o también mediante otras uniones por material líquido, como por ejemplo soldadura con o sin aportación. By means of a longitudinal guide thus generated, a tube can be laid in a defined place on the plate. There it is fixed, preferably glued, supported by the longitudinal guide on the plate, of which there is at least one. This can be done, for example, by adhesive or also by other joints made of liquid material, such as welding with or without contribution.
De manera especialmente preferente se utiliza para la fijación adhesiva una banda adhesiva. Al respecto se trata preferiblemente de una banda adhesiva de plástico o de una banda adhesiva con un enfundado de aluminio. Especially preferably an adhesive strip is used for adhesive fixation. In this regard, it is preferably a plastic adhesive strip or an adhesive strip with an aluminum sheath.
Preferiblemente forma el tubo un tubo de protección para un sensor de temperatura. En un tal tubo de protección se inserta el tubo capilar de un interruptor térmico, que conecta y desconecta el compresor del aparato refrigerador. Alternativamente puede servir el tubo también para proteger líneas eléctricas o similares. Además puede ser el propio tubo un sensor de temperatura. Preferably the tube forms a protective tube for a temperature sensor. In one such protection tube the capillary tube of a thermal switch is inserted, which connects and disconnects the compressor from the cooling apparatus. Alternatively, the tube can also be used to protect power lines or the like. In addition, the tube itself can be a temperature sensor.
La placa está compuesta preferentemente por dos capas de placa, apoyadas esencialmente una en otra, pero que en al menos una capa de la placa están abombadas en el lugar del canal, de los que al menos hay uno, para formar el hueco del canal. Preferiblemente están compuestas ambas capas de la placa entre las que está conformada la imagen del canal por hierro o bien, con especial en preferencia, aleación de aluminio. La placa según la invención puede fabricarse de forma conocida, en particular mediante unión por laminación. The plate is preferably composed of two layers of plate, supported essentially one on the other, but which in at least one layer of the plate are domed in the place of the channel, of which there is at least one, to form the hollow of the channel. Preferably both layers of the plate are composed between which the image of the channel is formed by iron or, especially preferably, aluminum alloy. The plate according to the invention can be manufactured in a known manner, in particular by rolling bonding.
Preferiblemente está configurado el evaporador como evaporador Rollbond o Z-Bond, en el que junto al canal de medio refrigerante, de los que al menos hay uno, está realizado al menos un canal que sirve como guía longitudinal para el tubo y configurado como canal ciego. Esto tiene la ventaja de que el canal que constituye la guía longitudinal para el tubo puede fabricarse de la misma manera y a la vez con la figura del canal de los canales de medio refrigerante. La expresión "canal ciego" significa que este canal o bien estos canales no está/n unido/s con la imagen del canal para el medio refrigerante. No obstante los mismos se generan preferiblemente de la misma manera que el canal de medio refrigerante, de los que al menos hay uno, con lo que no es necesaria ninguna etapa de trabajo adicional. Preferably the evaporator is configured as a Rollbond or Z-Bond evaporator, in which next to the cooling medium channel, of which there is at least one, at least one channel is used that serves as a longitudinal guide for the tube and configured as a blind channel . This has the advantage that the channel that constitutes the longitudinal guide for the tube can be manufactured in the same way and at the same time with the figure of the channel of the cooling medium channels. The expression "blind channel" means that this channel or these channels is not connected with the image of the channel for the cooling medium. However, they are preferably generated in the same manner as the cooling medium channel, of which there is at least one, so that no additional work stage is necessary.
Otras ventajas de la invención son que la placa ya no tiene que mecanizarse tras el proceso de insuflado y estampado, que la configuración plana de los canales ciegos origina menos daños en el transporte y que no es necesario impermeabilizar los extremos de los canales. Así pueden reducirse considerablemente los costes totales. Other advantages of the invention are that the plate no longer has to be machined after the insufflation and stamping process, that the flat configuration of the blind channels causes less transport damage and that it is not necessary to waterproof the ends of the channels. Thus, total costs can be significantly reduced.
La invención está orientada también a un aparato refrigerador que presenta un evaporador según la invención. Con especial preferencia es el aparato refrigerador un aparato refrigerador doméstico, en particular un armario frigorífico, un armario congelador o un arcón congelador. The invention is also directed to a cooling apparatus having an evaporator according to the invention. With particular preference is the refrigerating apparatus a domestic refrigerating apparatus, in particular a refrigerating cabinet, a freezer cabinet or a freezer chest.
