Abstract
(DE)
Die Erfindung betrifft einen Verdampfer für eine hermetische, mit einem phasenwechselnden Kältemittel befüllte Kühleinrichtung sowie dessen Verwendung vorzugsweise zur Kühlung von Halbleiterbauelementen oder Photovoltaikmodulen. Die Aufgabe der Erfindung besteht darin, den Herstellungsaufwand für flächig ausgebildete Verdampfer zu reduzieren und die Effizienz von Kühleinrichtungen mit Flächenverdampfern zu verbessern. Der erfindungsgemäße Verdampfer für eine mit einem phasenwechselnden Kältemittel befüllte hermetische Kühleinrichtung umfasst einen Träger, der mit Kältemittelkanälen versehen ist. Eine erste Folie (1), die mit wenigstens einer ersten, einen Expansionsraum bildenden Ausprägung (3) sowie wenigstens einer weiteren, einen in den Expansionsraum mündenden Zuführkanal (4) bildenden Ausprägung und wenigstens einer dritten, einen vom Expansionsraum ausgehenden Ableitkanal (5) bildenden Ausprägung versehen ist, ist mit wenigstens einer zweiten Folie (2) flächig die Ausprägungen hermetisch abdeckend verbunden. Jede einen Zuführkanal (4) bildende Ausprägung ist über eine hermetisch anschließbare Verbindungsleitung an den Ausgang eines Verflüssigers und jede einen Ableitkanal (5) bildende Ausprägung ist über eine hermetisch anschließbare Verbindungsleitung an den Eingang eines Verdichters anschließbar.

The invention relates to an evaporator for a hermetic cooling device filled with a phase-changing refrigerant and to the use of said evaporator preferably to cool semiconductor components or photovoltaic modules. The problem of the invention is to reduce the manufacturing expense for flatly designed evaporators and to improve the efficiency of cooling devices having flat evaporators. The evaporator according to the invention for a hermetic cooling device filled with a phase-changing refrigerant comprises a substrate that is provided with refrigerant channels. A first film (1), which is provided with at least one first stamping (3) that forms an expansion chamber and at least one further stamping that forms a feed channel (4) that opens into the expansion chamber and at least one third stamping that forms a drain channel (5) coming out of the expansion chamber, is connected to at least one second film (2) so as to hermetically cover the stampings extensively. Each stamping that forms a feed channel (4) can be connected to the outlet of a condenser by means of a hermetically connectible connecting line, and each stamping that forms a drain channel (5) can be connected to the inlet of a compressor by means of a hermetically connectible connecting line.

L'invention concerne un évaporateur pour un dispositif frigorifique hermétique rempli d'un fluide frigorigène à changement de phase, ainsi que son utilisation, de préférence pour le refroidissement de composants semiconducteurs ou de modules photovoltaïques. L'objectif de l'invention est de réduire le coût de fabrication des évaporateurs plats et d'améliorer l'efficacité des dispositifs frigorifiques équipés d'évaporateurs plats. L'évaporateur selon l'invention pour un dispositif frigorifique hermétique rempli d'un fluide frigorigène à changement de phase comprend un support qui est doté de canaux pour le fluide frigorigène. Un premier film, qui comprend au moins un premier gaufrage formant un espace d'expansion et au moins un autre gaufrage formant un canal d'amenée débouchant dans l'espace d'expansion et au moins un troisième gaufrage formant un canal d'évacuation quittant l'espace d'expansion, est recouvert d'au moins un deuxième film sur sa surface, en fermant de manière hermétique les gaufrages. Chaque gaufrage formant un canal d'amenée peut être relié à la sortie d'un condenseur par une conduite de liaison raccordée hermétiquement et chaque gaufrage formant un canal d'évacuation peut être relié à l'entrée d'un condenseur par une conduite de liaison raccordée hermétiquement.
