Description

Device for tempering objects

The present invention relates to a device for controlling the temperature of

Objects, in particular a temperable holding device such as beverage containers or the like.

It is known to provide a plurality of receptacles for beverage containers in interiors of motor vehicles to provide the vehicle occupant with the desired comfort, which is formed by such storage facilities for beverage containers such as cups, bottles or cans. These receptacles may optionally have insulating properties. To store beverage containers or other items to be tempered at the desired temperature, many vehicles are equipped with temperature-controlled devices for receiving beverage containers or other objects. The recording devices can

Beverage containers or objects warm and / or cool. There are already recording devices for objects known in which the

Heat input or heat removal is carried out via areal air conditioning units, which can be placed on side or bottom portions of the receiving device. The recording device is for this purpose completely made of a most expensive material with high thermal conductivity, such as aluminum or thermally conductive

Plastic, made. As a result, heat and / or cold can be transmitted via conduction, convection or radiation. Here is a large-scale, full-scale

Enclosing the recording device with temperature-controlled surfaces of the

Recording device necessary to achieve the desired temperature of the

Beverage container to provide. The recording device is for

Beverage stabilization in their temperature-controlled surface only interrupted by holding elements. In this approach, however, is disadvantageous that a large thermal mass must be heated or cooled. This prolongs the reaction time of the entire system. In addition, the positioning of the flat

Air conditioning units on side or bottom portions of the receiving device have an inhomogeneous temperature of the receiving device result. Therefore, often a high energy consumption may be required to heat or cool the respective beverage container. Also, in many cases, an additional insulating layer of a poor thermal conductivity material is necessary, which surrounds the entire layer with high thermal conductivity. An object of the present invention can therefore be seen to provide a device for controlling the temperature of objects, which allows improved temperature control of the objects. Next to be heated or cooled by the device objects with less energy. The device should also be easy and inexpensive to produce.

The above object is achieved by a device comprising at least two layers for the temperature control of objects such as beverage containers or the like, which comprises the features of patent claim 1. Further advantageous

Embodiments are described by the subclaims. Thus, in order to achieve the stated object, the invention proposes a device comprising at least two layers for the temperature control of objects, such as

Beverage containers or the like, which comprises a first inner layer, which first inner layer provides a receptacle for a respective object to be tempered. The receptacle provided by the first inner layer can be designed with regard to its shape such that the respective beverage container in the

Substantially immobile and preferably held by positive engagement and / or clamping by the recording. Also, the attachment of the object to be tempered centering holding elements in the recording is conceivable. Furthermore, the device has a second outer layer, which surrounds the first inner layer at least in sections and preferably all around and has a lower thermal conductivity than the first inner layer. A further component of the device is at least one tempering element for providing heat energy and / or cooling energy for the respective object to be tempered. The at least one tempering element is directly in surface contact with the first inner layer.

If in the present context of layers is mentioned, so it may be meant in particular surfaces or functional surfaces, eg. In the form of trough-shaped receptacles or open-top hollow cylindrical receiving troughs for receiving and a heat-conducting surface contact producing fixation of beverage containers of all kinds, eg Cups or bottles o. The like. Therefore, if in the following context of outer shell surfaces or inner shell surfaces is mentioned, this may in particular be the respective inner or outer surfaces of the hollow cylindrical, open-top receiving troughs. Such a device for tempering objects has a

comparatively simple construction with only a few to combine

Function elements on. For the preparation of the device are only a few

Components necessary, which can save costs compared to the production of conventional devices for temperature control.

In a first embodiment variant of the device for tempering objects, the at least one tempering element is formed from at least one tempering strand. In this case, the at least one Temperierlitze can be wound around an outer circumferential surface of the first inner layer. In the outer circumferential surface of the first inner layer can be introduced in this case, at least one trough, within which runs the at least one Temperierlitze. The trough preferably has a constant cross section in its course. Through the hollow, the at least one

Temperierlitze be positioned or stabilized in a planned course. Preferably, the at least one trough or the at least one

Temperierlitze a spiral or circular course. In this case, the at least one Temperierlitze or the trough in several spiral or

run circular turns, which turns preferably extend at a constant distance from each other over the outer circumferential surface of the first inner layer. In this way, a homogeneous temperature of the object to be tempered or recording can be made possible. The second outer one

Layer may be in surface contact with the first inner layer and the at least one Temperierlitze.

In a second embodiment variant of the device for tempering objects, the at least one tempering element is also at least one

Temperierlitze formed. Here, the at least one Temperierlitze is fixed and / or positioned by means of a support member to the first inner layer. The support element can be, for example, a nonwoven fabric, scrim, fabric or the like, on which the at least one tempering strand is sewn on. The at least one Temperierlitze can be held by a sewing thread used in this position. It is conceivable to use a nonwoven fabric, scrim or fabric of a non-decomposable material which does not decompose, for example, when injecting or attaching a material of the second outer layer and thus remains as an intermediate layer. Here, the application of glass, carbon, graphite or plastics with a high melting point is conceivable. Furthermore, a decomposable material for the nonwoven, scrim or fabric can be used, which For example, decomposed or volatilized during or after injection or application of a material of the second outer layer. In this case, a gas or air layer can form between the first inner layer and the second outer layer, as a result of which an additional thermal barrier or insulating layer can arise between the first inner material or the at least one tempering strand and the second outer material. With such an embodiment of the decomposable nonwoven, fabric or fabric, the diameter of the material of the second outer layer can be reduced compared to the first embodiment variant. As suitable materials for the decomposable nonwoven, scrim or fabric here, for example, plastics with a low melting point or natural fibers have been found.

Furthermore, it is conceivable that the carrier element is a net, a grid or the like, on which net or grid or on its mesh, the at least one Temperierlitze is sewn. Here, the at least one

Temperierlitze be held in position by means of a used sewing thread. Also, the at least one Temperierlitze can be threaded through the net or grid or its mesh, leaving them in the intended position.

The use of a film as a carrier element for the at least one Temperierlitze is conceivable. In this embodiment, the at least one

Temperierlitze be glued to the film. The film may consist of a non-decomposable material, which does not decompose, for example, when injecting or attaching a material of the second outer layer, so that an intermediate layer is maintained between the first inner layer and the second outer layer. A suitable material for a non-decomposable film is a plastic with a higher melting point. Furthermore, as a carrier element for the at least one Temperierlitze to be adhered a decomposable film may be provided, which decomposes or volatilizes, for example, during or after injecting or attaching a material of the second outer layer. As a result, a gas or air layer may form between the first inner layer or the at least one Temperierlitze and the second outer layer. By the gas or

Air layer may form a thermal barrier or an additional insulating layer, whereby the diameter of the material of the second outer layer compared to the first embodiment can be further reduced. Suitable materials for such a decomposable film are in particular plastics with a low melting point. Also in the previously illustrated embodiments of the device, which provide a support element in the form of a nonwoven, Geleges or fabric, a network or grid, or a film, is for the provision of a homogeneous

Temperierung the recording, in particular a spiral or circular arrangement of the at least one Temperierlitze on the

Outer shell surface of the first inner layer advantageous.

In a further embodiment, the at least one tempering element can be designed as at least one positive temperature coefficient element (PTC element). For fixation and / or positioning of the at least one PTC element on the first inner layer, a carrier element may likewise be provided here. This carrier element may in particular be a foil to which the at least one PTC element is glued, printed, etched or arranged in another way. The film may be formed of a non-decomposable material which does not decompose upon injection or attachment of a material of the second outer layer, for example, and thus remains as an intermediate layer between the first inner layer and the second outer layer. Preferably, plastics with a higher melting point are suitable as the material for the non-decomposable film. It is also conceivable to use a decomposable film which decomposes or volatilizes, for example, during injection or application of a material of the second outer layer, as a result of which a gas or air layer is interposed between the first inner layer or the at least one PTC element and the second outer layer Layer can arise. Through the gas or air layer, a thermal barrier or an additional thermally insulating layer can be formed, which is why a reduction of the material of the second outer layer compared to the first embodiment is conceivable. In particular, a material such as a plastic having a low melting point is suitable for the decomposable film.

A further embodiment variant of the device provides for the at least one tempering element to be applied or positioned on the first inner layer by means of a process of so-called digital direct metallization (DDM technology). It is also conceivable to use at least one tempering element in the form of at least one tempering foil. The tempering film may at least partially, but preferably completely cover the outer circumferential surface of the first inner layer and thereby be in contact with the surface of the first inner layer. When using a tempering is for positioning and / or fixation of at least one Temperierelements on the outer circumferential surface of the first inner layer no

additional support element necessary.

Furthermore, according to a further embodiment variant of the device, it can be provided that the at least one tempering element is completely accommodated in the first inner layer. In this case, the at least one tempering element can be injected into the first inner layer. The at least one tempering element may be, for example, at least one tempering strand or at least one PTC element. Also in these two embodiments of the device can by a spiral or circular arrangement of the at least one

Tempering be provided a homogeneous temperature of the object to be tempered or recording. Furthermore, a use of at least one tempering in the form of a tempering is conceivable.

In a preferred embodiment of the device according to the invention, the first inner layer at least partially has a smaller cross-section than the second outer layer. Preferably, the material of the first inner layer is a highly thermally conductive material, such as aluminum or a highly thermally conductive plastic, or a material which is a larger

Thermal conductivity has as the second outer layer. Furthermore, the material of the first inner layer can be an electrically conductive material or an electrically nonconductive material. As an electrically non-conductive material, for example, an electrically and thermally conductive plastic, such as a plastic with graphite filling or a metal such as aluminum or copper is suitable. For electrically non-conductive materials in particular an electrically non-conductive and thermally conductive plastic such as a plastic with mineral filling has proven to be applicable. If an electrically conductive material is used for the first inner layer, it may possibly

be necessary to make an electrical insulation of the at least one tempering of the material of the first inner layer. This can be done, for example, by means of a coating of the material of the first inner layer, an introduction of an electrically insulating film or a coating of the at least one

Tempering, for example by means of a lacquer layer done. When using an electrically non-conductive material for the first inner layer usually no additional electrical insulating layer between the material of the first inner layer and the at least one tempering is necessary. The material of the second outer layer may be a material which is only slightly thermally conductive, such as a plastic having poor thermal conductivity, or a material which has a lower thermal conductivity than the first inner layer. It is conceivable to choose a material which, in addition to an insulating effect, has a supporting effect for the one inner layer. For example, as the material of the second outer layer, a plastic can be selected, by means of which the first inner layer is overmolded. By means of the plastic, further regions surrounding the first inner layer can also be filled. Furthermore, for the second outer layer, a material can be selected which has no supporting effect for the first inner layer, but merely provides an insulating function for the first inner layer or the receptacle. Such a material may, for example, be a foam which is glued all over to the outer circumferential surface of the first inner layer. The use of a polyurethane foam is conceivable. The polyurethane foam can be injected into a mold in which the material of the first inner layer and the at least one tempering element are inserted. Alternatively, a surface-spraying of a polyurethane foam onto the material of the first inner layer and of the at least one tempering element by means of nozzles is also possible. In these ways, the device can be adapted to countless different environments or conditions, resulting in a universally applicable device for temperature control of objects such as in particular beverage containers.

It is also conceivable to design the device such that several, but in particular two objects such as beverage containers tempered or

can be included. For this purpose, the first inner layer may have two

form independent recordings for the respective object to be tempered. For tempering the two objects, it may be that each of the at least two positions independent of the other tempering element

Tempering element has, so that a different temperature control of the two objects can be made possible. By means of a separating element, a first receptacle can be formed, which is designed for preferably positive reception of a first object with a first maximum cross-sectional diameter and a second receptacle, which is designed for preferably positive reception of a second object with a second maximum cross-sectional diameter, wherein the second maximum cross-sectional diameter opposite the first maximum

Cross-sectional diameter can be increased or decreased. That way you can a plurality of objects with different geometries or sizes are recorded by means of a recording device.

In the following, embodiments of the invention and their advantages with reference to the accompanying figures will be explained in more detail. The proportions of the individual elements to one another in the figures do not always correspond to the actual size ratios, since some shapes are simplified and other shapes are shown enlarged in relation to other elements for better illustration.

The illustrated embodiments are only examples of how the device according to the invention can be designed and do not represent a final limitation.

In Fig. 1 a, a first embodiment of a device 2 for temperature control of objects such as beverage containers is shown. In this case, the device 2 comprises a first inner layer 4 and a second outer layer 6 surrounding the first inner layer 4 on an outer circumferential surface 4 '. The first inner layer 4 forms an upwardly open receiving unit 8 for receiving objects in the exemplary embodiment shown. Preferably, the material of the first inner layer 4 is a highly thermally conductive material, such as aluminum or a highly thermally conductive plastic, or to a material which has a greater thermal conductivity than the second outer layer 6 of the device 2. In the The material of the second outer layer 6 is preferably a material which is only slightly thermally conductive, such as a plastic with poor thermal conductivity, or a material which has a lower thermal conductivity than the first inner layer 4. A tempering element 10 is in the first inner layer 4 is injected or received in the first inner layer 4, so that the tempering 10 is completely within the first inner layer 4. Usually, the first inner layer 4 has a smaller cross-section than the outer second layer 6 in order to ensure an ideal transfer of the heat and / or cooling energy provided by the tempering element 10 to the object or the receiving unit 8 to be tempered. The tempering element 10 may be, for example, a tempering strand

12, which is injected into the first inner layer 4 and encloses the receiving unit 8 therethrough. The temperature-controlling strand 12 can be completely accommodated in the first inner layer 4. In this case, the Temperierlitze 12 is a single strand be formed, which spirally wound at constant intervals several times around the first inner layer 4. Furthermore, the use of a plurality of individual strands of Temperierlitze 12 is conceivable, which in each case at preferably constant intervals to each other enclose the first inner layer 4 and each may be coupled together. In this way, a homogeneous tempering of the object to be tempered or the receiving unit 8 can take place. In the embodiment of FIG. 1 b, instead of a tempering strand 12, a tempering foil 14 is injected or taken up in the material of the first inner layer 4. Because of the strong

Thermal conductivity of the first inner layer 4 can be easily transferred heat and / or cooling energy from the Temperierlitze 12 to the receiving unit 8. To control the heat and / or cooling energy to be transmitted to the receiving unit 8, a control device, not shown, may be provided.

2, a second embodiment of a device 2 for temperature control of objects such as beverage containers is shown. According to the

Embodiment of Figs. 1a and 1b, the device 2 comprises a first inner

Layer 4 and a first outer layer 4 surrounding all surrounding second outer layer 6. The first inner layer 4 forms an upwardly open receiving unit 8 for receiving objects. Preferably, the first inner layer 4 has a smaller cross-section than the second outer layer 6. On the outer lateral surface 4 'of the first inner layer 4 is a tempering element 10 or a plurality of individual tempering elements 10 coupled together (abbreviated to a tempering element 10). so that the tempering element 10 is located between the first inner layer 4 and the second outer layer 6 of the device 2 and is in surface contact with the first inner layer 4. The tempering element 10 extends over the outer circumferential surface 4 'of the first inner layer 4, as indicated by the reference numeral 10', and is positioned by means of a carrier element 20 (see Fig. 3a to 6c) or on the material of the first inner Layer 4 fixed.

FIGS. 3a and 3b each show a first embodiment of the second

Embodiment of the device 2. Here, a cross section through the first inner layer 4, the second outer layer 6 and the temperature control element 10 is shown. In this embodiment, the tempering 10 is formed as a Temperierlitze 12. Here, too, the temperature-controlling strand 12 can be formed as a single strand, which spirally winds around the first inner layer 4 several times. However, the use of a plurality of individual strands of Temperierlitze 12 is also conceivable, each spaced from each other, the first inner layer 4 at the Outer jacket surface 4 'enclose circular and can be coupled together. For positioning or fixing the Temperierlitze 12 on the outer circumferential surface 4 'of the first inner layer 4, a support member 20 is provided.

According to FIG. 3 a, the support element 20 is a fleece, scrim or fabric 22. The tempering strands 12 can be sewn onto the nonwoven, scrim or fabric 22. Here, the Temperierlitze 12, as shown in Fig. 3c, fixed by a sewing thread 40 used and held in position. The material of the nonwoven, fabric or web 22 may be a material which does not degrade upon injection or application of a material of the second outer layer 6, and thus remains intact as an intermediate layer 22 '. Here is the

Application of glass, carbon, graphite or plastics with a high

Melting point as a material for the non-decomposable nonwoven, scrim or fabric 22 conceivable.

Furthermore, the use of a material for the nonwoven, scrim or fabric 24 is also conceivable, which decomposes or volatilizes during or after injecting drier attaching a material of the second outer layer 6. As a result, the formation of a gas or air layer 24 ', as shown in FIG. 3 b, is conceivable, whereby an additional thermal barrier or insulating layer is formed between the first inner material 4 or the tempering strand 12 and the second outer material 6. With such an embodiment of the decomposable nonwoven, fabric or fabric 24, the diameter of the material of the second outer layer 6 can be reduced in comparison, for example, to the first embodiment variant of the device 2 (compare FIGS. 1a and 1b). As suitable materials for the decomposable nonwoven, scrim or fabric 24 in this case, for example, plastics with a low melting point or natural fibers have been found.

A second embodiment of the second embodiment of the device 2 can be seen in Figs. 4a and 4b. As tempering 10 is also a here

Temperierlitze used 12, which by means of a support member 20 at the

Outer shell surface 4 'of the first inner layer 4 is positioned or fixed. Fig. 4a provides as a support member 20 before a network or grid 26. Here, the Temperierlitze 12 is threaded through the mesh 26 'of the network or grid 26, as shown in particular Fig. 4c, and thus remains in the intended position. Furthermore, it is also conceivable to sew the tempering strand 12 onto the mesh 28 'of a net or grid 28, as illustrated by FIG. 4b, in particular by FIG. 4d. By sewing thread 40 is the Temperierlitze 12 fixed on the mesh 28 'of the network or grid 28 and held in position.

In a third embodiment of the second embodiment of the device 2, as shown in Fig. 5a and 5b, in turn, a tempering 10 is provided in the form of Temperierlitze 12, which by means of a support member 20 at the

Outer shell surface 4 'of the first inner layer 4 is positioned or fixed. According to FIG. 5a, a foil 30 is used as the carrier element 20, onto which the tempering strand 12 is glued (see FIG. 5c). The film 30 decomposes upon injection or

Attaching a material of the second outer layer not, so that a

Intermediate layer 30 'is maintained between the first inner layer 4 and the second outer layer 6. As a suitable material for the non-degradable film 30, a plastic with a higher melting point is suitable here.

Furthermore, as the carrier element 20 for the Temperierlitze 12 to be adhered also a film 32 may be provided, which decomposes or volatilizes during or after injecting or attaching a material of the second outer layer 6.

In this way, a gas or air layer 32 'between the first inner layer 4 and the Temperierlitze 12 and the second outer layer 6 arise, as Fig. 5b shows.

The gas or air layer 32 'can form a thermal barrier or additional insulating effect, as a result of which the diameter of the material of the second outer layer can be further reduced in comparison to the first embodiment variant of the device 2. As a material for such a decomposable film 32 are particularly suitable plastics with a low melting point.

Figs. 6a and 6b show a fourth embodiment of the second

Embodiment of the Device 2. In this case, instead of a tempering wire 12, a positive temperature coefficient element 16 or a plurality of positive temperature coefficient elements 16 (PTC element 16 for short) is used as tempering element 10. Also in this embodiment, a support member 20 is provided. In the event that a single PTC element 16 is provided, this can lie in a spiral on the outer circumferential surface 4 'of the first inner layer 4. If a plurality of PTC elements 16 are provided, a circular arrangement of the individual PTC elements 16 at at approximately approximately constant intervals on the outer circumferential surface 4 'of the first inner layer 4 is appropriate. As a support member 20 in this case also a film 30 is provided. The PTC element 16 or the plurality of PTC elements 16 can, as shown in FIG. 6 a and in particular FIG. 6 c, be glued to the film 30. The film 30 is made of a Material formed which does not decompose upon injection or attachment of a material of the second outer layer 6 and therefore as an intermediate layer 30 'between the first inner layer 4 and the second outer layer 6 is maintained. Preferably, plastics having a higher melting point are used here as material for the non-decomposable film 30.

According to FIG. 6b, it is also conceivable to use a film 32 which decomposes or volatilizes when injecting or attaching a material of the second outer layer 6, as a result of which a gas or air layer 32 'is interposed between the first inner layer 4 and the PTC. Element 16 or the plurality of PTC elements 16 and the second outer layer 6 may arise. A thermal barrier or additional thermally insulating layer can be formed by the gas or air layer 32 ', which is why it is conceivable to reduce the material of the second outer layer in comparison to the first embodiment variant of the device 2. In particular, suitable for the film 32 is a material such as a plastic with a low melting point. A third embodiment variant of the device 2 is shown in FIGS. 7a and 7b.

As tempering 10 here a Temperierlitze 12 is provided. To provide a temperature control of the receiving region 8 of the device 2, this is wound around the first inner layer 4. In order to fix and stabilize the tempering strands 12, depressions 34 are introduced into the material of the first inner layer 4 in the area of the outer jacket surface 4, within which the tempering strands 12 are placed. The troughs 34 preferably have an at least approximately constant cross-section. It can be provided that the temperature strand 12 is formed as a single strand, which spirally winds several times around the outer circumferential surface 4 'of the first inner layer 4. It is also conceivable to use a plurality of individual strands of the tempering strands 12, which are each arranged in a circle on the outer circumferential surface 4 'of the first inner layer 4 and enclose the first inner layer 4 at least approximately uniformly spaced from one another. The several strands of the

Temperierlitze 12 can be coupled together. Corresponding to the configuration of the temperature-controlling strand 12, the depressions 34 can also be formed as a single depression 34 surrounding the first inner layer several times or as a plurality of individual circumferential grooves 34. After wrapping the first inner layer 4 with the Temperierlitze 12 material of the second outer layer can be injected or attached to or on the first inner layer 4 and the Temperierlitze 12. Fig. 8 shows a fourth embodiment of the device 2. Here is a

Temperierelement 10 by means of a process of digital direct metallization (DDM method) to the first inner layer 4 and the outer circumferential surface 4 'of the first inner layer 4 applied. The second outer layer 6 preferably surrounds the first inner layer 4 all around.

The invention has been described with reference to a preferred embodiment. However, it will be apparent to those skilled in the art that modifications or changes may be made to the invention without departing from the scope of the following claims.

The holding device is intended for the interior of a vehicle.

To be tempered objects are in particular beverage containers, electrical

Charging devices or mobile phones.

The distribution layer preferably has a higher thermal conductivity than the support layer.

"Layer" means any structure having a predominantly 2-dimensional extent, even if this extension is not flat but curved in space, for example as a hollow cylinder or hollow sphere. "Layer" also includes fabrics with breaks, e.g. Fiber composite materials, nets or similar It is expedient if heat is preferably exchanged with the object to be tempered via the distribution layer. A heat flow through the support layer should be prevented as possible in the standard case. Therefore, it is appropriate if

the thermal conductivity of the distribution layer is higher than that of the support layer,

the thermal conductivity of the material of the distribution layer is higher than that of the material of the support layer and / or

- The specific thermal conductivity of the material of the distribution layer is higher than that of the material of the support layer.

All three properties apply in particular in the direction radial to

tempering object, or perpendicular to the respective local interface between distribution and support layer. Preferably, the tempering (10) is at least partially directly to the distribution layer (4) or is connected to this.
