Description
Technisches GebietTechnical area
Die Erfindung betrifft ein Kreislaufwärmerohr, das die Effizienz des Arbeitsfluidkreislaufs erhöhen kann.The invention relates to a cycle heat pipe that can increase the efficiency of the working fluid circuit.
Stand der TechnikState of the art
Mit der Erhöhung der Arbeitsleistung der elektronischen Produkte steigt auch die Wärme der elektronischen Bauelemente für die Signalverarbeitung und Berechnung. Die häufig verwendeten Kühlelemente sind Wärmerohr, Kühlkörper, Vapor-Chamber-Kühler usw., die durch den Kontakt mit den elektronischen Bauelementen die Wärme der elektronischen Bauelemente ableiten, um eine Übertemperatur der elektronischen Bauelemente zu vermeiden.As the performance of electronic products increases, so does the heat of electronic components for signal processing and calculation. The commonly used cooling elements are heat pipes, heat sinks, vapor-chamber coolers, etc., which dissipate the heat of the electronic components through contact with the electronic components in order to avoid overheating of the electronic components.
Der Kühlventilator erzeugt zwangsläufig einen Luftstrom, der die Wärme der Kühlelemente abführen kann. Wenn der Raum begrenzt ist, kann der Kühlventilator nicht verwendet werden.The cooling fan inevitably generates an air flow that can dissipate the heat of the cooling elements. If space is limited, the cooling fan can not be used.
Das Kreislaufwärmerohr weist einen Verdampfungskörper und einen Kondensationskörper auf, die durch ein Rohr miteinander verbunden sind. Dadurch ist die Wirkung des Arbeitsfluidkreislaufs besser. Im Verdampfungskörper ist eine Kapillarstruktur angeordnet, durch die das Arbeitsfluid zurückfließen kann. Die Kapillatrstruktur besitzt eine Vielzahl von Nuten, entlang denen der Dampf fließen kann. Der Verdampfungskörper steht mindestens an einer Seite mit der Wärmequelle in Kontakt. Das Arbeitsfluid im Verdampfungskörper wird durch die Wärme der Wärmequelle verdampft. Der Dampf fließt entlang den Nuten aus dem Verdampfungskörper und durch das Rohr in den Kondensationskörper. Dort wird der Dampf kondensiert. Das kondensierte Arbeitsfreid fließt in den Verdampfungskörper zurück.The cycle heat pipe has an evaporation body and a condensation body which are connected to each other by a pipe. As a result, the effect of the working fluid circuit is better. In the evaporation body, a capillary structure is arranged, through which the working fluid can flow back. The capillary structure has a plurality of grooves along which the vapor can flow. The evaporation body is in contact with the heat source at least on one side. The working fluid in the evaporator body is vaporized by the heat of the heat source. The steam flows along the grooves from the evaporation body and through the tube into the condensation body. There the steam is condensed. The condensed Arbeitsfreid flows back into the evaporation body.
Der herkömmliche plattenförmige Verdampfungskörper weist im Inneren einen Kompensationsraum und einen Dampfkern (Kapillarstruktur mit Dampfkanal) auf, die aufeinander oder nebeneinander angeordnet sind.The conventional plate-shaped evaporation body has inside a compensation space and a steam core (capillary structure with steam channel), which are arranged on or next to each other.
Wenn der Kompensationsraum und der Dampfkern aufeinander angeordnet sind, wird die Dicke des Verdampfungskörpers vergrößert. Dies ist ungünstig für eine kompakte Form.When the compensation space and the steam core are arranged on each other, the thickness of the evaporation body is increased. This is unfavorable for a compact form.
Wenn der Kompensationsraum und der Dampfkern in der horizontalen Richtung nebeneinander angeordnet sind, ist der Abstand des Kompensationsraums von der Verdampfungsfläche des Dampfkerns zu groß, wodurch eine Trockenverbrennung auftreten kann.When the compensation space and the steam core are arranged side by side in the horizontal direction, the distance of the compensation space from the evaporation area of the steam core is too large, whereby dry combustion may occur.
Daher zielt der Erfinder darauf ab, ein Kreislaufwärmerohr anzubieten, das die obergenannten Nachteile der herkömmlichen Lösung überwinden kann.Therefore, the inventor aims to offer a cycle heat pipe that can overcome the above disadvantages of the conventional solution.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Kreislaufwärmerohr schaffen, das eine Trockenverbrennung beim plattenförmigen Verdampfungskörper vermeiden kann.The invention has for its object to provide a Kreislaufwärmerohr that can avoid dry combustion in the plate-shaped evaporation body.
Diese Aufgabe wird durch das erfindungsgemäße Kreislaufwärmerohr gelöst, das umfasst:
- • einen Verdampfungskörper, der eine Austrittsöffnung, eine Eintrittsöffnung und einen Aufnahmeraum aufweist, wobei im Aufnahmeraum eine Kapilllarstruktur, ein Kompensationsraum und mindestens ein Dampfkanal vorgesehen sind, wobei der Dampfkanal an einem Ende mit der Austrittsöffnung verbunden ist,
- • ein Rohr, das ein erstes Ende und ein zweites Ende aufweist, die mit der Austrittsöffnung und der Eintrittsöffnung des Verdampfungskörpers verbunden sind, und
- • eine Kondensationseinheit, die sich zwischen dem ersten und zweiten Ende des Rohrs befindet.
- An evaporation body having an outlet opening, an inlet opening and a receiving space, wherein a capillary structure, a compensation space and at least one steam channel are provided in the receiving space, wherein the steam channel is connected at one end to the outlet opening,
- • A tube having a first end and a second end, which are connected to the outlet opening and the inlet opening of the evaporation body, and
- • a condensation unit located between the first and second ends of the pipe.
Die Eintrittsöffnung des Verdampfungskörpers oder ein Ende des Rohrs befindet sich nahe an der Kapillarstruktur, wodurch die Rückflusswirkung des Arbeitsfluids verbessert wird, so dass eine Trockenverbrennung vermieden werden kann.The inlet opening of the evaporation body or one end of the tube is located close to the capillary structure, whereby the reflux effect of the working fluid is improved, so that dry combustion can be avoided.
