Unter einer „Kühlkreislaufvorrichtung“ soll insbesondere eine Vorrichtung verstanden werden, die Bestandteil zumindest eines Kühlkreislaufs ist.

beispielsweise einem Glykol-Wasser-Gemisch, von einem zu kühlenden Objekt, also einer Wärmequelle, zu einem zu wärmenden Objekt, also einer Wärmesenke, zu transportieren. Hierbei kann in Abhängigkeit von einem Betriebszustand zumindest eines der Objekte entweder als Wärmequelle oder als Wärmesenke fungieren. Insbesondere weist der Kühlkreislauf zumindest einen Kühlkörper auf, der dazu vorgesehen ist, Wärme aus dem Kühlkreislauf abzuführen und beispielsweise an umgebende Luft abzugeben.

A “cooling circuit” is intended, for example, to mean a unit that is intended to generate heat using a coolant, in particular a coolant. For example, a glycol-water mixture, from an object to be cooled, i.e. a heat source, to an object to be warmed, i.e. a heat sink. Depending on an operating state, at least one of the objects can function either as a heat source or as a heat sink. In particular, the cooling circuit has at least one heat sink, which is intended to remove heat from the cooling circuit and, for example, to release it to the surrounding air.

Die Verbindungseinheit 30 weist weiterhin korrespondierende Befestigungselemente 34 auf. Die korrespondierenden Befestigungselemente 34 sind an dem Fluidstromsteuerelement 20 ausgebildet. Die Rast- und/oder Klemmhaken 32 sind jeweils dazu vorgesehen, eines der korrespondierenden Befestigungselemente 34 zu umgreifen. Die korrespondierenden Befestigungselemente 34 sind als Dome ausgebildet, die aus dem Fluidstromsteuerelement 20 seitlich hervortreten. The connection unit 30 is designed as a snap-in and/or clamp connection unit. The connection unit 30 is intended to form and/or produce a bayonet connection. The connection unit 30 has, in the present case four, alternatively another suitable number, latching and/or clamping hooks 32. The latching and/or clamping hooks 32 are formed on the fluid guide unit 22. The latching and/or clamping hooks 32 are made of the same material as the fluid guide unit 22. The connecting unit 30 also has corresponding fastening elements 34. The corresponding fastening elements 34 are formed on the fluid flow control element 20. The latching and/or clamping hooks 32 are each intended to grip around one of the corresponding fastening elements 34. The corresponding fastening elements 34 are designed as domes that protrude laterally from the fluid flow control element 20.
Das Fluidstromsteuerelement 20 ist als Pumpeneinheit ausgebildet. Die Fluidleiteinheit 22 weist eine Ausnehmung 26 auf, die ein Pumpengehäuse bildet. Das Fluidstromsteuerelement 20 bildet gemeinsam mit dem Pumpengehäuse eine Pumpe aus. Die Kühlkreislaufvorrichtung 12 weist ein Dichtelement 28 auf, das zwischen dem Fluidstromsteuerelement 20 und der Fluidleiteinheit 22 angeordnet ist. Das Fluidstromsteuerelement 20 weist einen freiliegenden Impeller 21 auf. Der Impeller 21 ist in dem Pumpengehäuse angeordnet. Der Impeller 21 ist dazu vorgesehen, das Kühlfluid im Kühlkreislauf 11 anzutreiben. The fluid flow control element 20 is designed as a pump unit. The fluid guide unit 22 has a recess 26 which forms a pump housing. The fluid flow control element 20 forms a pump together with the pump housing. The cooling circuit device 12 has a sealing element 28 which is arranged between the fluid flow control element 20 and the fluid guide unit 22. The fluid flow control element 20 has an exposed impeller 21. The impeller 21 is arranged in the pump housing. The impeller 21 is intended to drive the cooling fluid in the cooling circuit 11.
Die Rast- und/oder Klemmhaken 32 sind in regelmäßigen Abständen um die Ausnehmung 26 angeordnet. Die korrespondierenden Befestigungselemente 34 sind ebenso in regelmäßigen Abständen zueinander, insbesondere um das Fluidstromsteuerelement 20, angeordnet. In einer Einbauposition sind die Rast- und/oder Klemmhaken 32 und die korrespondierenden Befestigungselemente 34 deckungsgleich angeordnet. Gemäß alternativen Ausgestaltungen können die Rast- und/oder Klemmhaken in unregelmäßigen Abständen zu einander angeordnet sein, so dass eine eindeutige Einbauposition festgelegt wird, in der die Rast- und/oder Klemmhaken deckungsgleich zu den korrespondierenden Befestigungselementen angeordnet sind. The latching and/or clamping hooks 32 are arranged at regular intervals around the recess 26. The corresponding fastening elements 34 are also arranged at regular intervals from one another, in particular around the fluid flow control element 20. In an installed position, the latching and/or clamping hooks 32 and the corresponding fastening elements 34 are arranged congruently. According to alternative embodiments, the latching and/or clamping hooks can be arranged at irregular distances from one another, so that a clear installation position is determined in which the latching and/or clamping hooks are arranged congruently with the corresponding fastening elements.
Bei einer Montage des Fluidstromsteuerelements 20 wird das Fluidstromsteuerelement 20 in einer ersten Bewegungsphase auf die Fluidleiteinheit 22 zubewegt, bis das Fluidstromsteuerelement 20 in der Ausnehmung 26 angeordnet ist.
In einer zweiten Bewegungsphase wird das Fluidstromsteuerelement 20 gegenüber der Fluidleiteinheit 22 rotiert, bis die korrespondierenden Befestigungselemente 34 von den Rast- und/oder Klemmhaken 32 umgriffen werden. Das Dichtelement 28 kann bei der Montage komprimiert werden und eine rückstellende Kraft auf die Verbindungseinheit 30 bewirken, die eine Klemmkraft verstärkt. When mounting the fluid flow control element 20, the fluid flow control element 20 is moved towards the fluid guide unit 22 in a first movement phase until the fluid flow control element 20 is arranged in the recess 26. In a second movement phase, the fluid flow control element 20 is rotated relative to the fluid guide unit 22 until the corresponding fastening elements 34 are gripped by the latching and/or clamping hooks 32. The sealing element 28 can be compressed during assembly and cause a restoring force on the connection unit 30, which increases a clamping force.
Gemäß alternativen Ausgestaltungen ist das Fluidstromsteuerelement als Ventileinheit ausgebildet. According to alternative embodiments, the fluid flow control element is designed as a valve unit.
Die Kühlkreislaufvorrichtung 12 kann weitere Fluidstromsteuerelemente, insbesondere weitere Pumpeneinheiten und/oder Ventileinheiten, aufweisen, die in gleicher Weise mit der Fluidleiteinheit 22 verbunden sind.

Eine Verbindungseinheit 30a der der Kühlkreislaufvorrichtung 12a ist dazu vorgesehen, eine Bajonettverbindung herzustellen. Die Verbindungseinheit 30a weist, im vorliegenden Fall vier, Rast- und/oder Klemmhaken 32a auf. Die Rast- und/oder Klemmhaken 32a weisen eine gemeinsame Basiskomponente 36a auf (vgl. auch Fig. 5 und 6). Alternativ kann jeder Rast- und/oder Klemmhaken eine eigenen Basiskomponente aufweisen. Die Basiskomponente 36a ist in ein Gehäuse der Fluidleiteinheit 22a eingebettet. Die Basiskomponente 36a ist in das Gehäuse der Fluidleiteinheit 22a eingegossen. Die Basiskomponente 36a ist von einem Metall, insbesondere Edelstahl, gebildet. Die Basiskomponente 36a ist als Ringblech ausgebildet, aus dem mittels eines Stanzbiegeprozesses die Rast- und/oder Klemmhaken 32a
ausgeformt sind. Die Basiskomponente 36a umringt eine Ausnehmung 26a, in der das Fluidstromsteuerelement 20a angeordnet ist und/oder die ein Pumpengehäuse für einen Impeller des Fluidstromsteuerelements 20a bildet. Die Rast- und/oder Klemmhaken 32a beginnen an der Basiskomponente 36a und ragen aus dem Gehäuse hervor. Die Rast- und/oder Klemmhaken 32a weisen eine intrinsische Federwirkung auf, die dazu vorgesehen ist, das Fluidstromsteuerelement 20a gegen die Fluidleiteinheit 22a zu pressen, um so eine Klemmkraft zu verstärken. Korrespondierende Befestigungselemente 34a der Verbindungseinheit 30a sind an dem Fluidstromsteuerelement 20a ausgebildet. An zumindest einem der korrespondierenden Befestigungselemente 34a und/oder an zumindest einem der Rast- und/oder Klemmhaken 32a kann ein Anschlag ausgebildet sein, der eine Rotation des Fluidstromsteuerelements 20a gegenüber der Fluidleiteinheit 22a begrenzt.
Figure 4 shows a further cooling circuit device 12a with a fluid guide unit 22a and a fluid flow control element 20a. A connection unit 30a of the cooling circuit device 12a is intended to produce a bayonet connection. The connection unit 30a has, in the present case, four latching and/or clamping hooks 32a. The latching and/or clamping hooks 32a have a common base component 36a (see also FIGS. 5 and 6). Alternatively, each latching and/or clamping hook can have its own base component. The base component 36a is embedded in a housing of the fluid guide unit 22a. The base component 36a is cast into the housing of the fluid guide unit 22a. The base component 36a is formed from a metal, in particular stainless steel. The base component 36a is designed as a ring plate from which the locking and/or clamping hooks 32a are made using a stamping and bending process are formed. The base component 36a surrounds a recess 26a in which the fluid flow control element 20a is arranged and/or which forms a pump housing for an impeller of the fluid flow control element 20a. The latching and/or clamping hooks 32a begin on the base component 36a and protrude from the housing. The latching and/or clamping hooks 32a have an intrinsic spring effect, which is intended to press the fluid flow control element 20a against the fluid guide unit 22a in order to increase a clamping force. Corresponding fastening elements 34a of the connection unit 30a are formed on the fluid flow control element 20a. A stop can be formed on at least one of the corresponding fastening elements 34a and/or on at least one of the latching and/or clamping hooks 32a, which limits a rotation of the fluid flow control element 20a relative to the fluid guide unit 22a.
