Description

Technical Field

[0001] The invention relates to a motor vehicle, comprising a thermal management system and an at least partially electrified power unit, the thermal management system being configured to condition / control the temperature of the interior air of the motor vehicle and / or to condition the temperature of at least one electrified vehicle component, in particular a battery storage unit, assigned to the electrified power unit, wherein the thermal management system can be coupled to at least one separate transport container in such a way that the temperature-controlled air can be introduced into the container interior through a corresponding air inlet section and can be drawn out of the container interior through a corresponding air outlet section, wherein the thermal management system is configured to cool the air introduced into the container interior to an air temperature below 0° C., in particular below −5° C., and the thermal management system is configured to heat the air introduced into the container interior to an air temperature above 50° C. The invention also relates to a transport container, in particular a thermostatic compartment / insulated box, for a motor vehicle. Background Art

[0002] Such a motor vehicle is known from German patent application DE 10 2023101 009 by the same applicant which was not published at the time of filing the present application.

[0003] In addition, with regard to thermostatic compartments, reference is made to DE 10 2020 204 510 A1, DE 41 03 044 A1 and KR 20140 089 215A.

[0004] With known transport containers, it has been found that contamination can occur at the connection between the transport container and the thermal management system or at the air inlet or air outlet in the container interior. In addition, there is the problem that the transported goods can at least partially cover such air openings, thereby impairing the desired thermal effect (cooling or heating). Summary of the invention

[0005] It is therefore an object of the present invention to provide a motor vehicle or a transport container with which the above-mentioned disadvantages can be avoided.

[0006] This object is achieved by a motor vehicle and a transport container having the features of the respective independent claims. Advantageous embodiments with expedient developments are given in the dependent claims.

[0007] The invention therefore proposes a motor vehicle, comprising a heat management system and an at least partially electrified power unit, the heat management system being configured to temperature the interior air of the motor vehicle and / or temperature the at least one electrified vehicle component, in particular a battery storage unit, associated with the electrified power unit, wherein the heat management system can be coupled to at least one separate transport container in such a way that the temperature-conditioned air can be introduced into the container interior via a corresponding air inlet section and can be removed from the container interior via a corresponding air outlet section, wherein the heat management system is configured to cool the air introduced into the container interior to an air temperature below 0° C., in particular below −5° C., and the heat management system is configured to heat the air introduced into the container interior to an air temperature above 50° C. It is provided that the air inlet section and the air outlet section have an air-permeable cover facing the container interior, the cover being configured to provide an intermediate space between at least one inner wall of the transport container and the transported goods received in the transport container, in which intermediate space the temperature-conditioned air can diffuse / disperse, in particular can be introduced into the transport container and / or can be removed from the transport container.

[0008] By means of such a covering device, the transported object can be kept at least at a small distance from the air inlet section or the air outlet section, so that the air inlet or the air outlet is not disturbed or is only slightly disturbed. It should be noted in this context that the intermediate space formed by means of the covering element can be designed in different ways depending on the transported object, in particular its properties or dimensions.

[0009] In a motor vehicle, the covering device can be a grid element that protrudes into the interior of the container.

[0010] The grid element can be arranged in the region of the inner wall of the transport container at or beside the relevant openings of the air inlet section and / or the air outlet section. This provides a locally arranged grid element.

[0011] In this case, the grille elements can have a shape that enables the temperature-controlled air to be introduced or removed in a plurality of directions, in particular in a direction substantially orthogonal to the relevant inner wall and in a direction substantially parallel to the relevant inner wall.

[0012] In a motor vehicle, the covering device can be supported on the relevant inner wall by a plurality of spacers and / or the covering device can be designed to be self-supporting.

[0013] Alternatively, the covering device can also be formed by a planar grid element which has essentially the same area as the inner wall and is arranged at a desired distance from the inner wall.

[0014] In the motor vehicle, the air inlet section can have at least one access to the container interior, which is arranged in a first side wall of the transport container, and the air outlet section can have at least one access to the container interior, which is arranged in a second side wall of the transport container. This reduces the risk of contamination of the accesses compared to arranging the accesses in the bottom of the transport container.

[0015] The first side wall and the second side wall can be opposite to each other. This ensures that the temperature-controlled air flows through the entire container interior, thereby achieving a temperature distribution that is as uniform as possible.

[0016] In a motor vehicle, for coupling to a vehicle-side air duct of a thermal management system, the air inlet section and the air outlet section have corresponding coupling sections arranged in the bottom of the transport container, wherein the air inlet section and the air outlet section extend between the coupling section and the opening inside the container bottom and the associated side wall.

[0017] In a motor vehicle, the transport container can have at least one thermal storage element. Such a storage element is particularly designed to be able to heat or cool to a desired temperature for the transported goods during travel and when the transport container is in use in such a way that the storage element continues to function as a heating element or cooling element after the travel has ended and the transport container has been removed from the motor vehicle.

[0018] A transport container, in particular a thermostatic compartment, for the above-mentioned motor vehicle is also proposed. It is provided that the air inlet section and the air outlet section of the transport container have an air-permeable cover facing the container interior, which is configured to provide an intermediate space between at least one inner wall of the transport container and the transported goods received in the transport container, in which intermediate space the temperature-controlled air can diffuse unhindered, in particular can be introduced into the transport container and / or can be drawn out of the transport container.

[0019] Furthermore, with regard to the transport container itself, the transport container can have at least one of the above-mentioned features. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] exist Figure 1 The motor vehicle 10 is shown in simplified and schematic form as a dashed rectangle in FIG. The motor vehicle 10 has an at least partially electrified drive unit 12 , which is likewise shown only schematically as a rectangle.

[0028] The motor vehicle 10 further comprises a thermal management system 14, which is configured to control the temperature of the interior air IL of the motor vehicle, as indicated by corresponding outline arrows. In addition, the thermal management system 14 is configured to control the temperature of at least one electrified vehicle component 16 assigned to the electrified power unit 12. The electrified vehicle component 16 may be, for example, a battery storage unit or an electrical control unit or the like.

[0029] The thermal management system 14 is coupled or can be coupled to a separate transport container 20 that is Figure 1 2 is shown in a simplified and schematic cross-sectional view.

[0030] The transport container 20 can also be referred to as a constant temperature compartment. It is essentially formed by a container bottom 22, a container wall 24 and a container cover 26, which together define a container interior 28. The container cover 26 is connected to the container wall 24, for example, in a form-fitting and / or force-fitting manner. Instead of the container cover, one or more covers for opening the container can also be mounted on the side.

[0031] The heat management system 14 is coupled to the transport container 20 in such a way that temperature-controlled air can be introduced into the container interior 28 via the air supply section 30 and can be discharged from the container interior 28 via the air discharge section 32. The heat management system is configured to cool the air introduced into the container interior 28 to an air temperature below 0° C., in particular below −5° C. The heat management system is also configured to heat the air introduced into the container interior 28 to an air temperature above 50° C.

[0032] The transport container 20 has a container wall, in particular an air inlet coupling 34 and an air outlet coupling 36 on the container bottom 22. Figure 1 As can be seen, the air inlet coupling and the air outlet coupling are coupled or can be coupled to an air supply section 30 and an air discharge section 32 of the thermal management system 14 .

[0033] exist Figure 1 The coupled state of the transport container 20 in the motor vehicle 10 is shown in FIG. Figure 2 The state is shown in which the transport container 20 is removed from the motor vehicle 10 or inserted therein, but is not coupled to the thermal management system 14 . Figure 2 Use in Figure 1 Correspondingly, the above Figure 1 The description also applies to Figure 2 .

[0034] from Figure 1 and Figure 2 It can be seen that the air inlet section 30 and the air outlet section 32 have corresponding closure elements 38, which are configured to close the air inlet section 30 and the air outlet section 32 when the transport container 20 is not coupled, which can be seen in particular from Figure 2 see.

[0035] The air inlet section 30 and the air outlet section 32 may be arranged inside the motor vehicle 10 in the rear region of the motor vehicle 10 , in particular between the rear seat arrangements or in the luggage compartment of the motor vehicle 10 . Figure 1 and Figure 2 , a luggage compartment floor 42 is shown in simplified form on which the transport container 20 is supported or can be supported. As can be seen from the figure, the air inlet section 30 and the air outlet section 32 extend through the luggage compartment floor 42, so that the air inlet section and the air outlet section can be accessed from the upper side of the luggage compartment floor.

[0036] As an alternative to the luggage compartment floor, the transport container can also be connected to other structural components, such as the side of the interior panel, wherein the air inlet and the air outlet are arranged accordingly on / in the relevant component. In addition to the fluidic coupling between the transport container 20 and the thermal management system 14, the transport container can also be connected to other vehicle components, which is simplified by the rectangle 60 and the connection point 62. For example, the transport container 20 can also be connected to a seat back and / or an interior panel element of the motor vehicle 10.

[0037] The thermal management system 14 is configured to compensate for air pressure differences resulting from air temperature differences between the temperature in the container interior 28 and the temperature in the vehicle interior. For this purpose, a pressure equalization device 40, such as a pressure equalization valve fluidically connected to the interior or body space of the motor vehicle, can be assigned to the air inlet section 30 and / or the air outlet section 32.

[0038] Depend on Figure 1 and Figure 2 It can also be seen that corresponding closure elements 44 are arranged on the transport container 20 at the air inlet coupling 34 and the air outlet coupling 36 in order to separate the container interior 28 from the environment in a fluidic manner when not coupled to the thermal management system 14, which is particularly important in the case of Figure 2 Shown in.

[0039] At least one pressure equalization device 46 can be assigned to the transport container 20, which is configured to equalize air pressure differences arising from air temperature differences between the temperature in the container interior 28 and the temperature in the vehicle interior. Such a pressure equalization device 46, for example in the form of a pressure equalization valve, can be arranged, for example, in the container wall 24.

[0040] In the transport container 20, at least one fastening device 50 for transported objects and / or at least one partitioning device 52 for transported objects may be arranged in the container interior 28. The fastening device 50 may be, for example, a bottle rack or a device such as a belt for fixing the transported objects. The partitioning device 52 may be, for example, a vertical or horizontal partition wall that divides the container interior 28 into different areas.

[0041] Figure 3 The transport container 20 is shown without the thermal management system 14. Figure 3 In the transport container, the air input section 30 and the air outlet section 32 have an air-permeable covering device 70 facing the container interior 28, which is configured to provide an intermediate space ZR between at least one inner wall 22i of the transport container 20 (here for example the bottom 22) and the transported goods 72 received in the transport container (which are simplified as a rectangle with rounded corners), in which the temperature-controlled air KL can diffuse unhindered, in particular can be introduced into the transport container 20 and / or can be extracted from the transport container 20.

[0042] exist Figure 3 In the example of FIG. 2 , the covering device 70 is designed as a grid element protruding into the container interior 28 , which is indicated by the dashed illustration.

[0043] The grid element as the covering device 70 can be, for example, a profile made of metal or plastic. Figure 3 As shown in FIG. , the covering device can be shaped in a self-supporting manner so that the transport object 72 can be supported on the covering device.

[0044] like Figure 3As shown, grid elements are arranged as covering devices 70 in the region of the inner wall 22 i of the transport container 20 at the respective openings 30 m , 32 m of the air inlet section 30 and / or the air outlet section 32 .

[0045] The grille element as covering device 70 can have a shape that enables temperature-controlled air KL to be introduced or removed in multiple directions, in particular in a direction substantially orthogonal to the relevant inner wall 22i and in a direction substantially parallel to the relevant inner wall 22i.

[0046] exist Figure 4 , an example of a transport container 20 is shown with a flat grid element as a cover 70. The grid element rests on a plurality of spacers 74 which are supported on the associated inner wall 22i, here on the bottom 22 of the transport container 20.

[0047] exist Figure 5 , an example of a transport container 20 is shown, wherein an air inlet section 30 has a plurality of openings 30m leading to a container interior 28, which are arranged in a first side wall 24 (shown here on the left) of the transport container 20. An air outlet section 32 has a plurality of openings 32m leading to a container interior 28, which are arranged in a second side wall 24 (shown here on the right) of the transport container 20. In this case, the two side walls 24 are arranged opposite one another.

[0048] exist Figure 5 In the example of , a covering device 70 in the form of a flat grid element is arranged along each of the two side walls 24. The respective grid element is supported or held on the respective side wall 24 by means of spacers 74. In this structure, an intermediate space ZR is also formed between the transported object 72 and the inlet 30m, 32m, so that the temperature-controlled air KL can flow or circulate relatively freely.

[0049] Above Figures 3 to 5 The transport container 20 can be used in the same manner as Figure 1 and Figure 2 The thermal management system 14 is shown connected or coupled. Figure 5 As shown, the air input section 30 and the air outlet section 32 can have coupling sections 34, 36 respectively arranged in the bottom 22 of the transport container 20 so as to be coupled to the vehicle-side air channel of the thermal management system 14, wherein the air input section 30 and the air outlet section 32 extend inside the container bottom 20 and the relevant side wall 24 between the coupling sections 34, 36 and the inlet portions 30m, 32m.

[0050] according to Figure 4 of transport containers, Figure 6It is shown that the heat storage element 76 can optionally be arranged in or on the transport container 20. In the example shown, the corresponding heat storage element 76 is arranged in the two side walls 24. It should be noted that such a storage element 76 can also be arranged in the cover 26 or in the bottom 20 of the transport container 20. In addition, such a storage element 76 can be arranged with reference to Figures 1 to 5 Each shipping container combination in the described shipping containers.
