Description

[0001] The present invention relates to a switching system comprising a first and a second switching device for forming and separating a thermal bridge between a first environment and a second environment, having a first heat transfer section for thermally contacting the first environment and a second heat transfer section for thermally contacting the second environment.

[0002] Switching devices for forming and separating a thermal bridge or thermal bridges between two environments are known in the prior art. These can be used, for example, to create a temperature range for batteries in one environment in which good efficiencies can be achieved. For example, DE 103 19 350 A1 discloses a battery box module for a vehicle that has a mechanically robust box for accommodating a vehicle battery. The box has a double-walled construction with switchable vacuum insulation that can be switched between a thermally pass-through state and a thermally insulated state. Such a device is complex and expensive to construct. Furthermore, the range of applications for such a device is relatively limited.

[0003] US 2005 / 0045307 A1 discloses a system for adjusting a thermal bridge between a heat source and a heat sink, in which various wedge bodies stacked on top of each other with different thermal conductivities are movable relative to each other. Such a system is also complicated in design and inflexible in use.

[0004] European patent application EP 2 814 106 A2 discloses a device for forming and separating a thermal bridge between two environments, in which two wedge-shaped guide sections are displaceable relative to one another in order to contact the guide sections to form the thermal bridge between the two environments and to space the guide sections apart to separate the thermal bridge between the two environments. Such a device is inexpensive in construction, but due to its wedge shape, requires a relatively large installation space, particularly if a thermal bridge is to be formed or separated between the two environments over larger surface areas.

[0005] This may be necessary, for example, if the interior of a vehicle needs to be temperature-controlled. In this case, the interior of the vehicle forms a first environment, and the area outside the vehicle forms a second environment. Various temperature control devices are known in the prior art for temperature-controlling the interior of a vehicle.

[0006] Another switching device is also known from US 2014 / 0 137 570 A1.

[0007] The air conditioning of an automotive interior is generally based on the principle of heat exchange through air circulation or the targeted generation of an air flow. This can be achieved through appropriate ventilation nozzles in the area of ​​an instrument panel, the roof lining, or the footwell, or through the integration of air ducts into textile structures, such as the seat. Other typical applications include the integration of appropriate heating conductors into textile fabrics or even 3D structures for heating the seat area or the steering wheel. The use of such heating surfaces is also possible for heating the vehicle interior. In this case, surface heating systems are integrated as a component of a composite component, for example, into the interior door panel or the roof lining. The large surface area is intended to enable particularly advantageous utilization of the generated radiant heat.However, the systems based on heating conductors mentioned above do not have a cooling function due to their principle.

[0008] Another possible method for air conditioning is the integration of hose systems into textile structures. By controlling the temperature of the fluid used, this principle can be used to increase the temperature and cool the seat. However, as with airflow-based air conditioning, such systems require a suitable air conditioning unit.

[0009] The aforementioned active temperature control devices all have the disadvantage that they require temperature control components that generate unusable waste heat when the temperature control device is in operation. If such a temperature control device is used to cool a vehicle, it consumes electrical energy for temperature control, which is very high compared to the primary use of a vehicle as a means of transportation, especially an electric vehicle, and thus significantly reduces the range. Furthermore, the heat exchangers required for a conventional temperature control device in the form of a known air conditioning system, along with various other components, have additional weight, which must be reduced in view of the increasingly important lightweight construction of vehicles in the future.

[0010] In the field of passive thermal management, i.e., the situational modification of the thermal behavior of structural components, approaches exist that alter the thermal conductivity by deliberately aligning particles suspended in a carrier fluid. Such so-called electro- or magnetorheological fluids (ERFs or MRFs) respond to the application of a corresponding field by forming particle chains that conduct heat flows better than fluids with stochastically distributed particles. However, such systems are complex and correspondingly expensive.

[0011] The object of the present invention is to at least partially address the problems described above. In particular, the object of the present invention is to provide a system for improved thermal management between two environments, in particular between the interior of a vehicle and the vehicle's surroundings.

[0012] The above object is achieved by the patent claims. Further features and details of the invention emerge from the description and the drawings. Features described in connection with the switching device naturally also apply in connection with the system according to the invention, and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is always made to each other.

[0013] According to a first, unclaimed, aspect of the present invention, a switching device is provided for forming and separating a thermal bridge between a first environment and a second environment. The switching device has a first heat transfer section for thermally contacting the first environment and a second heat transfer section for thermally contacting the second environment. The first heat transfer section has a plurality of thermally conductive first conducting sections and a plurality of thermally insulating first insulating sections, which are arranged alternately next to one another. The second heat transfer section has a plurality of thermally conductive second conducting sections and a plurality of thermally insulating second insulating sections, which are arranged alternately next to one another. The conducting sections have a higher thermal conductivity than the insulating sections.Furthermore, according to the present invention, the first heat transfer section and the second heat transfer section are arranged to be movable relative to each other for switching between a conducting switching state in which the first conducting sections are in surface contact with the second conducting sections and an insulating switching state in which the first conducting sections are in surface contact with the second insulating sections and / or the second conducting sections are in surface contact with the first insulating sections.

[0014] The design of the switching device provides an at least partially passive temperature control device that is space-saving, cost-effective, reliable and easy to operate.

[0015] In the present case, a thermal bridge is understood to mean, in particular, a heat transport section for good heat conduction between the first environment and the second environment. In the case of a formed thermal bridge, or more precisely a plurality of thermal bridges, heat conduction can accordingly take place through the heat transfer sections or the conducting sections between the first environment and the second environment. In the case of a separate or non-formed thermal bridge, in principle no or only very little heat conduction can take place between the first environment and the second environment through the heat transfer sections or conducting sections, or at least a significantly weaker heat conduction between the first environment and the second environment compared to the case of a formed thermal bridge.

[0016] The first environment and the second environment are each to be understood as an open or closed space, for example. The first environment can, for example, be an external environment outside an object to be temperature-controlled, for example a vehicle. The second environment can, for example, be an internal environment within the object to be temperature-controlled. The first environment and the second environment can each also be designed as solid, liquid, or gaseous masses or a corresponding body. The first environment is delimited by at least a first environmental boundary, and the second environment is delimited by at least a second environmental boundary, wherein the switching device can be arranged between the first environmental boundary and the second environmental boundary.More specifically, the present switching device can be arranged such that the first heat transfer section for thermally contacting the first environment can be arranged at the first environmental boundary and the second heat transfer section for thermally contacting the second environment can be arranged at the second environmental boundary.

[0017] In the case of thermal contact between the first heat transfer section and the first environment or the second heat transfer section and the second environment, the first heat transfer section and the first environment or the second heat transfer section and the second environment are preferably in direct, physical contact. However, it is also possible that in the case of thermal contact between the first heat transfer section and the first environment or the second heat transfer section and the second environment, one or more intermediate elements are arranged between the first heat transfer section and the first environment or the second heat transfer section and the second environment. What is crucial is that in the case of thermal contact between the first heat transfer section and the first environment or the second heat transfer section and the second environment, a corresponding thermal bridge is formed orgood heat conduction is possible.

[0018] The heat transfer sections are preferably plate-shaped. The conducting sections comprise a material with good thermal conductivity, preferably more than 5 W / m*K, for example, metal. The insulating sections comprise a material with poor thermal conductivity, preferably less than 1 W / m*K, for example, a suitable plastic, a foam, or fiber material. Furthermore, it is possible for the insulating sections not to comprise a solid material but to form a substantially empty space that is filled, for example, only with ambient air. In this case, a heat transfer section can be serrated in cross-section, at least in sections, wherein the serrations or the corresponding projections, which are preferably directed toward the other heat transfer section, form the conducting sections, and the spaces or grooves between the projections form the insulating sections.Such projections and / or grooves are preferably rectangular or substantially rectangular in cross section.

[0019] The solution according to the invention is particularly advantageous for electric and plug-in hybrid vehicles, since in such vehicles, not only efficient, active heating and cooling generation but also effective thermal management are crucial. Furthermore, the components of the present switching device can easily be integrated into a thermal management system with the components already present in the vehicle concept. As a result, only a correspondingly small number of additional components are required for effective vehicle air conditioning.

[0020] The possible targeted heat dissipation or heat absorption via components in the interior and / or body area of ​​the vehicle by the present switching device represents an innovative approach in which heat exchange can be realized in a substantially passive manner via the prevailing temperature gradient between the environment inside the vehicle and the environment outside the vehicle. The switching device according to the invention can be easily arranged on large, thermally effective component surfaces, such as in the area of ​​an instrument panel or a textile interior of a vehicle.

[0021] The conducting sections and insulating sections are preferably arranged alternately next to one another such that one conducting section always follows an insulating section. The conducting sections and the insulating sections are preferably arranged flush with one another, with the conducting sections and / or the insulating sections also preferably extending across the entire width of the respective heat transfer section. This makes it possible to achieve a particularly effective temperature control effect. It is also advantageous if the heat transfer sections are each designed to be flexible or elastically deformable, at least in some regions. This allows the heat transfer sections or the corresponding switching device to be placed particularly advantageously in uneven or curved regions between the first environment and the second environment. For this purpose, it can be advantageous if the insulating sections comprise an elastomer or are designed as an elastomer section.

[0022] It is further advantageous if the first heat transfer section and the second heat transfer section are designed as identical or substantially identical heat transfer sections, which are preferably arranged on top of one another in a form-fitting or surface-fitting manner, at least in sections. The first heat transfer section and / or the second heat transfer section preferably each have an axial symmetry in a cross-section.

[0023] According to a further development of the present invention, it is possible for the first heat transfer section and the second heat transfer section to be arranged so as to be displaceable relative to one another for switching between the conducting switching state and the insulating switching state. By displacing the first heat transfer section relative to the second heat transfer section, switching between the conducting switching state and the insulating switching state is particularly easy. In the context of the present invention, displaceability is understood to mean the possibility of a guided linear movement of the heat transfer sections. For this purpose, the first heat transfer section and the second heat transfer section are preferably each mounted in a guide. The guide or the longitudinal direction of the guide is preferably arranged orthogonally or substantially orthogonally to the longitudinal direction of the conducting sections and / or the insulating sections.

[0024] It may be further advantageous within the scope of the present invention if the first heat transfer section and the second heat transfer section are displaceable relative to one another in a displacement direction for switching between the conducting switching state and the insulating switching state, and the first insulating sections and / or the second insulating sections each have a greater width in the displacement direction than the first conducting sections and / or the second conducting sections. This ensures reliable insulation between the first environment and the second environment in the insulating switching state.If the first insulating sections and / or the second insulating sections each have a greater width in the displacement direction than the first conductive sections and / or the second conductive sections, surface contact or other physical contact between the first conductive sections and the second conductive sections, and thus an unwanted thermal bridge in the insulating switching state, can be reliably prevented. Preferably, the first insulating sections have a greater width in the displacement direction than the second conductive sections, and the second insulating sections have a greater width in the displacement direction than the first conductive sections. Particularly preferably, the first insulating sections also have a greater width in the displacement direction than the first conductive sections, and the second insulating sections have a greater width in the displacement direction than the second conductive sections.The width of the insulating sections in the direction of displacement is preferably 10% to 50% larger than the width of the conductive sections.

[0025] Furthermore, according to the present invention, it is possible to provide an actuating mechanism for switching between the conducting switching state and the insulating switching state, by means of which the heat transfer sections can be moved relative to one another. The actuating mechanism enables active switching between the conducting switching state and the insulating switching state. As a result, the switching device can be easily switched between the conducting switching state and the insulating switching state, for example, by a user. For this purpose, at least one user-operable control element for switching between the conducting switching state and the insulating switching state is preferably assigned to the actuating mechanism. The actuating mechanism also preferably has an actuating motor, particularly preferably an electric motor, by means of which the switching device can be switched between the conducting switching state and the insulating switching state.Furthermore, it is preferred if the adjusting mechanism has an adjusting unit for each of the first heat transfer section and the second heat transfer section, so that the first heat transfer section is movable relative to the second heat transfer section and / or the second heat transfer section is movable relative to the first heat transfer section.

[0026] Furthermore, within the scope of the present invention, it is possible for the actuating mechanism to have a preload unit which, when the actuating mechanism is not activated, applies a preload force to the switching device or the respective heat transfer sections in the direction of the conducting switching state or in the direction of the isolating switching state. This makes it possible for the switching device to be mounted in a self-locking manner in a preferred position or a corresponding state and only needs to be actively deflected to deflect it into another position or a corresponding other state. For example, the preload unit can be adjusted depending on the environment in which the switching device or the object containing the switching device is predominantly located.For example, if the master switching state is desired more frequently, the preload unit can apply a preload force to the switching device in the direction of the master switching state when the actuating mechanism is not activated. If, on the other hand, the isolating switching state is desired more frequently, the preload unit can apply a preload force to the switching device in the direction of the isolating switching state when the actuating mechanism is not activated. This can reduce the actuation frequency of the actuating mechanism.

[0027] It can be further advantageous according to the invention if the adjusting mechanism moves the first heat transfer section and the second heat transfer section relative to one another depending on a temperature in the first environment and / or the second environment. As a result, the switching device can be switched into the conducting switching state or the isolating switching state automatically or depending on the temperature in the first environment and / or in the second environment. For this purpose, the adjusting mechanism has, for example, a bimetallic section which expands or contracts depending on the temperature in the first environment and / or in the second environment and switches the switching device accordingly, directly or via a further switching unit, into the conducting switching state or towards the conducting switching state or into the isolating switching state or towards the isolating switching state.Furthermore, it is possible for the actuating mechanism to have a pneumatic unit which is deflected depending on the temperature in the first environment and / or in the second environment and switches the switching device accordingly, directly or via a further switching unit, into the conducting switching state or in the direction of the conducting switching state or into the isolating switching state or in the direction of the isolating switching state.

[0028] According to a further development of the present invention, it is possible for the switching device to have at least one sensor for detecting a temperature in the first environment and / or the second environment, and for the actuating mechanism to move the first heat transfer section and the second heat transfer section relative to one another depending on the detected temperature in the first environment and / or the second environment. This makes it possible to switch the switching device specifically, i.e. depending on the detected temperature, into the conducting switching state or the isolating switching state. If, for example, a temperature higher than an upper threshold value is detected by a sensor for detecting a temperature in the first environment, the actuating mechanism can switch the switching device, for example, to the isolating switching state in order to prevent an undesired strong heat transfer from the first environment to the second environment.If, for example, a temperature sensor in the second environment detects a temperature lower than a lower threshold, the actuating mechanism can, for example, switch the switching device to the conducting switching state to enable greater heat transfer from the first environment to the second environment. Preferably, the switching device comprises a plurality of sensors, more specifically, a first sensor for detecting the temperature in the first environment and a second sensor for detecting the temperature in the second environment.If, for example, the first sensor detects a temperature higher than an upper threshold and the second sensor detects a temperature lower than a lower threshold, the actuating mechanism switches the switching device to the conducting state to enable a correspondingly strong heat transfer from the first environment to the second environment. Particularly preferably, the switching device further comprises a temperature comparison device for comparing a detected temperature in the first environment and a detected temperature in the second environment.If, for example, the first sensor detects a temperature that is higher than an upper threshold value, the second sensor detects a temperature that is also higher than the upper threshold value, and the comparison device determines that the temperature in the first environment is higher than the temperature in the second environment, the actuating mechanism can switch the switching device to the insulating switching state or hold it in the same in order to prevent the first environment from heating up further due to a correspondingly strong heat transfer from the first environment to the second environment.

[0029] According to a further aspect, a switching system is provided with a first switching device and a second switching device, wherein a heat storage medium is arranged between the two switching devices. The heat storage medium is arranged in thermal contact with the first heat transfer section and / or the second heat transfer section of the first switching device and in thermal contact with the first heat transfer section and / or the second heat transfer section of the second switching device. The heat storage device enables a stepped heat transfer from the first environment to the second environment or from the second environment to the first environment.If the switching device according to the invention is arranged, for example, in the roof area of ​​a vehicle, wherein the vehicle environment corresponds to the first environment and the interior of the vehicle corresponds to the second environment, the heat storage medium can be used, for example, to store heat from the interior of the vehicle. For this purpose, the second switching device can, for example, be switched to a conducting switching state and the first switching device to an insulating switching state. If the vehicle is now used in a cold environment, for example in winter, the first switching device can remain in the insulating switching state in order to retain the heat in the heat storage medium and / or in the interior of the vehicle. If, on the other hand, the vehicle is used in a warm environment, for example in summer, the first switching device can be switched to the conducting switching state in order to release the heat to the first environment and thereby cool down the heat storage medium.It is also conceivable that the heat storage medium can be "charged"—i.e., warmed up—independently of the temperature in the first environment and / or the second environment, in order to subsequently release heat into the interior of the vehicle, for example, in winter after leaving the garage. In the switching system according to the invention, the heat storage device is to be understood as an environment within the meaning of the present invention. The first switching device and the second switching device are preferably identical in design or at least have the same functional properties. The heat storage medium can be gaseous, liquid, or solid.

[0030] According to a further aspect of the present invention, a vehicle is provided with a switching system as described above, wherein the switching system is arranged in the body area, in particular in a roof and / or door area, or in the area of ​​an instrument panel of the vehicle. The vehicle according to the invention therefore also offers the same advantages as have been described in detail with reference to the switching device and / or the switching system according to the invention. The vehicle is preferably designed as a motor vehicle, in particular as a road vehicle, rail vehicle, watercraft or aircraft. The switching device and the switching system according to the invention can also be arranged in any other objects to form and separate a thermal bridge between a first environment and a second environment. This means that the present invention is not limited to use in a vehicle.

[0031] Further measures improving the invention will become apparent from the following description of various exemplary embodiments of the invention, which are schematically illustrated in the figures. All features and / or advantages apparent from the claims, the description, or the drawings, including structural details and spatial arrangements, may be essential to the invention both individually and in various combinations.

[0034] The first heat transfer section 20 and the second heat transfer section 30 are formed according to the Fig. 1 and Fig. 2, for switching between the conducting switching state S1, in which the first conducting sections 21 are in surface contact with the second conducting sections 31, and the isolating switching state S2, in which the first conducting sections 21 are in surface contact with the second isolating sections 32 and the second conducting sections 31 are in surface contact with the first isolating sections 22, are arranged so as to be displaceable relative to one another.

In addition, the first insulating sections 22 according to Fig. 1 and Fig. 2 have a greater width in the direction of displacement than the first conducting sections 21 and the second insulating sections 32 have a greater width in the direction of displacement than the second conducting sections 31.
