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 temperature-regulate / control the interior air of the motor vehicle and / or temperature-regulate at least one electrified vehicle component, in particular a battery storage unit, associated with the electrified power unit, wherein the thermal management system can be coupled to at least one separate transport container. Furthermore, the invention 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, regarding the constant temperature compartment, reference is made to CN 108 413 697A, US 4 841 742 A and KR 101166 667B1.

[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. There is also 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 present invention therefore proposes a motor vehicle, which includes a thermal management system and an at least partially electrified power unit, wherein the thermal management system is configured to temperature the interior air of the motor vehicle and / or temperature control at least one electrified vehicle component associated with the electrified power unit, in particular a battery storage unit, wherein the thermal management system can be coupled to at least one separate transport container in such a way that a container fluid circulating in the container walls of the transport container can be temperature controlled so that the air volume and / or the transported goods present in the container interior defined by the container walls can be temperature controlled by heat conduction and / or by natural convection or forced convection, wherein the air volume in the container interior is separated from the container fluid.

[0008] Thus, in such a transport container, air openings through which the temperature-controlled air must be introduced or removed can also be omitted. Accordingly, there are no openings that could contaminate and affect efficient operation. Instead, the inner wall of the transport container is heated or cooled by means of the container fluid, so that the desired temperature can be achieved in the container interior.

[0009] In the motor vehicle, the thermal management system can be coupled or can be coupled to the transport container in such a way that the container fluid is formed by the air temperature-controlled by the thermal management system. In other words, the transport container is connected with its fluid lines formed in the container wall to the circulation circuit for the temperature-controlled air of the thermal management system, so that the transport container or its container fluid lines themselves (temporarily) are part of the circulation circuit for the temperature-controlled air.

[0010] Alternatively, in a motor vehicle, the thermal management system and the transport container can be thermally connected via a heat exchanger arranged on the transport container, wherein the heat exchanger is configured to provide heat exchange between the container fluid and a working fluid of the thermal management system that is separated from the container fluid, wherein the working fluid is in particular temperature-controlled air.

[0011] The container fluid can therefore be different from the working fluid of the thermal management system. In particular, it is conceivable that the container fluid is a liquid which can be quickly heated or cooled by means of a heat exchanger.

[0012] It is also conceivable here that the container fluid can circulate within the container wall, in particular when using a container fluid pump or the like.

[0013] In the motor vehicle, at least one blower device may be arranged in the container interior, which blower device is configured to move an air volume present in the container interior.

[0014] If, for example, the container fluid circulates once along the circumference in the container wall, the blower device can be arranged in particular on the first side wall or the second side wall, through which the container fluid flows at a temperature that is (still) as high as possible or (still) as low as possible. Accordingly, the air that is heated or cooled more strongly at the side wall is distributed in the container interior, so that the air is heated or cooled as effectively and evenly as possible.

[0015] In a motor vehicle, thermal ribs / cooling fins can be arranged on at least one container wall, which protrude into the interior of the container. Such thermal ribs can be understood or referred to as heating ribs or cooling ribs, depending on their function. With the aid of such thermal ribs, the effective thermal surface in the interior of the container is enlarged, so that the air in the interior of the container can be heated or cooled more effectively.

[0016] In a motor vehicle, the transport container can have at least one heat storage element which is thermally connected to the container fluid. 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.

[0017] In a motor vehicle, the transport container can have a coupling section arranged in the bottom for coupling to a vehicle-side working fluid channel of a thermal management system. The coupling section can either be fluidically connected to a container fluid line, if the working fluid of the thermal management system (temperature-controlled air) is to be used as container fluid, or the coupling section can be fluidically connected to a heat exchanger, which enables heat transfer to the container fluid.

[0018] A transport container, in particular a thermostatic compartment, for a motor vehicle is also proposed. It is provided that the transport container contains a container fluid that circulates in the container walls, so that the air volume and / or the transported goods present in the container interior bounded by the container walls can be temperature-controlled by heat conduction and / or by natural or forced convection, wherein the air volume in the container interior is separated from the container fluid.

[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

[0020] Further advantages and details of the present invention are obtained from the following description of embodiments with reference to the accompanying drawings. The drawings show:

[0023] Figure 3 A motor vehicle is shown in a simplified and schematic manner with a transport container having a heat exchanger. DETAILED DESCRIPTION

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] The transport container 20 has an air inlet coupling 34 and an air outlet coupling 36 on the container wall, in particular 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 .

[0029] 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 .

[0030] 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.

[0031] 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.

[0032] 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.

[0033] The transport container 20 has fluid lines 70 in its container wall 24, ie, in particular in its container bottom 22 and side walls 24, in which the container fluid can circulate. The container fluid is guided into the fluid lines 70 so that the container fluid is separated from the air volume present in the container interior 28.

[0034] exist Figure 1 In the example of FIG. 1 , the fluid line 70 is connected to the air inlet coupling 34 and the air outlet coupling 36 , so that the fluid line 70 is fluidically connected or can be fluidically connected to the air supply section 30 and the air discharge section 32 of the thermal management system 14 .

[0035] The air KL which is temperature-controlled, in particular heated or cooled, by the heat management system 14 is referred to below as the working fluid of the heat management system 14 .

[0036] exist Figure 1 In the example of FIG. 5 , the working fluid of the thermal management system 14 is the same as the container fluid circulated in the fluid line 70. In other words, the working fluid of the thermal management system 14 is transported through the fluid line 70 of the transport container as the container fluid.

[0037] Thus, the container fluid circulating in the fluid lines 70 of the container walls 22, 24 of the transport container 20 can be temperature-controlled, so that the air volume present and / or the transported goods 72 present in the container interior 28 delimited by the container walls 22, 24 can be temperature-controlled by heat conduction and / or by natural or forced convection. As already described, the air volume of the container interior 28 is separated from the container fluid present or circulating in the fluid lines 70.

[0038] Figure 2The transport container is shown disconnected from the heat management system 14. The air-conducting sections in the transport container 20 and in the heat management system 14 are closed by corresponding manually or automatically actuatable closing elements 38 so that air cannot escape or contaminate unused air line sections.

[0039] Figure 3 Another example of a transport container 20 is shown. Figure 1 The transport containers 20 are constructed substantially the same. Figure 2 The fluid lines 70 in the transport container 20 form a closed system or a closed circulation loop for the container fluid BF contained therein.

[0040] When a heat exchanger 74 (which can also be referred to as an integrated heat exchanger) is arranged on or in the transport container 20, a thermal interaction or heat exchange is achieved between the container fluid BF (white outline arrow) and the working fluid KL of the thermal management system 14 (black arrow with double tips). Figure 3 In the example of FIG. 1 , the working fluid (temperature-controlled air KL) of the thermal management system 14 is different or inconsistent with the container fluid BF of the transport container 20. In particular, the container fluid BF may be a liquid, and the working fluid KL of the thermal management system 14 may be (temperature-controlled) air.

[0041] exist Figure 3 In the example of FIG. 2 , the fluid line 70 can be connected to a pump 76 , which is only schematically shown. With the help of such a pump 76 , the container fluid BF can circulate in the fluid line 70 of the container wall 22 , 24 .

[0042] In other words, the thermal management system 14 and the transport container 20 are thermally connected via a heat exchanger 74 arranged on the transport container 20, wherein the heat exchanger 74 is configured to provide heat exchange between the container fluid BF and a working fluid KL of the thermal management system 14 that is separated from the container fluid BF, wherein the working fluid KL is in particular temperature-controlled air.

[0043] From all Figures 1 to 3 It can be seen that at least one blower 78 is optionally arranged in the container interior 28, which is configured to move the air volume present in the container interior. The blower 78 can be mounted on the side wall 24, for example. Alternatively, it is also conceivable that the blower 78 is arranged on the container cover 26.

[0044] Also from all Figures 1 to 3It can be seen that the transport container 20 optionally has at least one heat storage element 80, which is directly or indirectly thermally connected to the container fluid BF. In the example shown, a corresponding heat storage element 80 is arranged in the side wall 24. It should be pointed out that such a storage element 80 can also be arranged in the cover 26 or the bottom 20 or in other side walls 24 of the transport container 20.
