Description

MANIFOLD FOR A THERMAL CIRCUIT OF AN ELECTRIC VEHICLE AS WELL AS
THERMAL CIRCUIT
FIELD OF THE INVENTION
[0001] The invention relates to a manifold for a thermal circuit of an electric vehicle. Moreover, the invention relates to a thermal circuit for an electric vehicle.
BACKGROUND INFORMATION
[0002] DE 10 2018 216 600 Al shows an arrangement for cooling components in a cooling circuit in an electric vehicle or a hybrid vehicle. Furthermore, US 2015/0135742 Al shows a liquid cooling circuit for a storage battery of an electric or hybrid motor vehicle. Moreover, WO 2020/089152 Al shows a heating or cooling circuit for an electric vehicle.
SUMMARY OF THE INVENTION
[0003] It is an object of the present invention to provide a manifold for a thermal circuit of an electric vehicle as well as a thermal circuit for an electric vehicle such that a fluid for cooling and/or heating at least one battery of the vehicle may be guided in a particularly advantageous way.
[0004] This object is solved by a manifold having the features of patent claim 1 as well as a thermal circuit having the features of patent claim 5. Advantageous embodiments with expedient developments of the invention are indicated in the other patent claims.
[0005] A first aspect of the present invention relates to a manifold for a thermal circuit of an electric vehicle. For example, the electric vehicle may be a commercial vehicle such as a truck. A fluid for cooling and/or heating at least one battery of the vehicle may flow through the thermal circuit which may act or function as a cooling circuit for cooling the battery and/or a heating circuit for heating the battery. The manifold according to the present invention comprises a delivery pipe through which the medium for cooling and/or heating the battery may flow. The delivery pipe comprises a first inlet by which at least one chiller for cooling the fluid is fluidically connectable with the delivery pipe such that the fluid may be introduced from the chiller into the delivery pipe via the first inlet. The delivery pipe further comprises a second inlet by which at least one heating device for electrically heating the fluid is fluidically connectable with the delivery pipe such that the fluid may be introduced from the heating device into the delivery pipe via the second inlet. For example, the heating device may be configured as or may comprise at least one Positive Temperature Coefficient (PTC) which is also referred to as a PTC element.
[0006] The delivery pipe further comprises a third inlet by which at least one radiator for cooling the fluid is fluidically connectable with the delivery pipe such that the fluid may be introduced from the radiator into the delivery pipe via the third inlet. Moreover, the delivery pipe comprises a first outlet by which the delivery pipe is fluidically connectable with a pump for conveying the fluid such that the fluid may be introduced from the delivery pipe into the pump via the first outlet. For example, the pump is configured to convey the fluid through the thermal circuit and thus through the delivery pipe. Preferably, the pump is configured as an electric pump. The first inlet, the second inlet, the third inlet and the first outlet are arranged in series along the delivery pipe.
[0007] The manifold according to the present invention further comprises a supply pipe through which the fluid may flow. Thus, the delivery pipe and the supply pipe are configured to guide the fluid. Preferably, the fluid is a liquid. The supply pipe comprises a second outlet by which the chiller is fluidically connectable with the supply pipe such that the fluid may be introduced from the supply pipe into the chiller via the second outlet. This means that the chiller may be supplied with the fluid by the supply pipe and the second outlet. Furthermore, the supply pipe comprises a third outlet by which a surge tank is fluidically connectable with the supply pipe such that the fluid may be introduced from the supply pipe into the surge tank via the third outlet. Thus, the surge tank may be supplied with the fluid by the supply pipe and the third outlet. Moreover, the supply pipe comprises a fourth outlet by which the heating device is fluidically connectable with the supply pipe such that the fluid may be introduced from the supply pipe into the heating device via the fourth outlet.
[0008] The supply pipe also comprises a fourth inlet by which a valve such as, for example, a 3/2 valve, is fluidically connectable with the supply pipe such that the fluid may be introduced from the valve into the supply pipe via the fourth inlet. The second outlet, the third outlet, the fourth outlet, and the fourth inlet are arranged in series along the supply pipe.
[0009] Moreover, the manifold according to the present invention comprises a bypass which is also referred to as a bypass pipe. The fluid may flow through the bypass such that the bypass is configured to guide the fluid. The bypass is fluidically connected with the delivery pipe and the supply pipe such that the fluid may be introduced from the supply pipe into the delivery pipe via the bypass thereby bypassing the chiller, the heating device and the surge tank. In other words, the fluid flowing through the bypass bypasses the chiller, the heating device and the surge tank (i.e., does not flow through the chiller, the heating device and the surge tank). By the manifold according to the present invention, the fluid may be guided in a particularly advantageous way. Moreover, the manifold can be installed, for example, on a component of the vehicle particularly easily. Preferably, the delivery pipe, the supply pipe and the bypass are connected with each other such that the manifold according to the present invention is an assembled module which may be handled and thus installed as a whole and thus particularly easily. In particular, an advantageous design with no or minimal scope of manual error may be realized. Moreover, by the manifold, the chance of air pockets in the manifold or the thermal circuit can be kept particularly low. For example, respective duct elements such as, for example, hoses may be fluidically connected with the respective inlets and outlets. Moreover, said ducked elements may be mechanically connected with the supply and delivery pipes thereby forming an assembly for guiding the fluid, wherein said assembly may be handled and installed as a whole and thus in a particularly easy and time-effective way. Moreover, failures in installing the manifold or said assembly may be avoided. Since the outlets and inlets are arranged in series, said duct elements may be placed or arranged tangentially in relation to the supply and delivery pipes which are also referred to as main pipes. Thus, a volume of the fluid, which is also referred to as a coolant, may be maximized and the chance of air pockets can be kept particularly low. Alternatively or additionally, the delivery pipe and/or the supply pipe may be designed with a variable diameter to achieve a particularly advantageous flow rate.
[0010] The invention also relates to a thermal circuit for an electric vehicle, the thermal circuit comprising a manifold according to the present invention. Advantages and advantageous embodiments of the manifold according to the present invention are to be regarded as advantages and advantageous embodiments of the thermal circuit according to the present invention and vice versa.

The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone can be employed not only in the respectively indicated combination but also in any other combination or taken alone without leaving the scope of the invention.

[0021] Fig. 1 shows part of a thermal circuit 10 for an electric vehicle. The electric vehicle may be configured as a commercial vehicle, in particular a truck. The electric vehicle comprises at least one electric machine configured to electrically drive the vehicle.
Moreover, the electric vehicle comprises at least one battery by which electrical energy is stored or may be stored. The electric machine may be supplied with the electrical energy stored in the battery such that, for example, the electric machine may be operated as an electric motor for electrically driving the electric vehicle. The battery may be a component which is arranged in the thermal circuit 10 through which a fluid may flow. Preferably, said fluid is a liquid. The fluid is also referred to as a coolant. As will be described in greater detail below, the fluid may be used to cool and/or heat the battery. For example, at least one further component or several further components may be arranged in the thermal circuit 10 such that, for example, the respective further component may be heated and/or cooled by the fluid.
[0022] The thermal circuit 10 comprises a manifold 12 which is shown in Fig. 2 in a schematic perspective view. The manifold 12 comprises a delivery pipe 14 through which the fluid for cooling and/or heating the battery may flow. As shown in Fig. 1, the thermal circuit 10 comprises a chiller 16 configured to cool the fluid. The delivery pipe 14 comprises a first inlet 18 by which the chiller 16 for cooling the fluid is fluidically connected with the delivery pipe 14 such that the fluid may be introduced from the chiller 16 into the delivery pipe 14 via the first inlet 18. In the embodiment shown in Fig. 1, a first duct element 20 is fluidically connected with the inlet 18 and the chiller 16 such that the fluid may be guided from the chiller 16 to the inlet 18 by the duct element 20 such that the fluid may flow from the chiller 16 through the duct element 20 and through the inlet 18 and into the delivery pipe 14 thereby guiding the fluid from the chiller 16 via the duct element 20 and the inlet 18 into the delivery pipe 14. The thermal circuit 10 further comprises a first heating device 22 and a second heating device 24 which are also referred to as FTC heaters. The heating devices 22 and 24 are also referred to as PTC. The heating device 22, 24 is an electric heating device configured to electrically heat the fluid. The delivery pipe 14 comprises a second inlet 26 by which the heating device 22 for electrically heating the fluid is fluidically connected with the delivery pipe 14 such that the fluid may be introduced from the heating device 22 into the delivery pipe 14 via the second inlet 26. In the embodiment shown in Fig. 1, a second duct element 28 is fluidically connected with the inlet 26 and the heating device 22 such that the fluid may be guided from the heating device 22 to the inlet 26 and into the delivery pipe 14 by or via the duct element 28. Moreover, the thermal circuit 10 comprises at least one radiator which is not shown in the figures. Thus, the fluid may flow through the radiator. Moreover, air such as, for example, ambient air may flow around the radiator thereby cooling the fluid flowing through the radiator. The delivery pipe 14 comprises a third inlet which cannot be seen in the figures. By the third inlet, said radiator for cooling the fluid is fluidically connected with the delivery pipe 14 such that the fluid may be introduced from the radiator into the delivery pipe 14 via the third inlet. In the embodiment shown in Fig. 1, a third duct element 30 is fluidically connected with the third inlet and the radiator such that the fluid flowing through the radiator may be guided from the radiator to the third inlet by the duct element 30. The delivery pipe 14 also comprises a first outlet 32 by which the delivery pipe 14 is fluidically connected with a pump 34 of the thermal circuit 10. This means that the thermal circuit 10 comprises the pump 34 configured to convey the fluid through the thermal circuit 10 and thus the manifold 12 which is also referred to as a PTC manifold. Preferably, the pump 34 is an electric pump (i.e., an electrically operable pump). Thus, the fluid may be introduced from the delivery pipe 14 into the pump 34 via the first outlet 32. As shown in Fig. 1, the first inlet 18, the second inlet 26, the third inlet, and the first outlet 32 are arranged in series along the delivery pipe 14, in particular along a flowing direction in which the fluid flows through the delivery pipe 14 (i.e., is conveyed through the delivery pipe 14 by the pump 34).
[0023] The manifold 12 further comprises a supply pipe 36 through which the fluid may flow. Thus, the delivery and supply pipes 14 and 36 are configured to guide the fluid. The supply pipe 36 comprises a second outlet which cannot be seen in the figures. By the second outlet, the chiller 16 is fluidically connected with the supply pipe 36 such that the fluid may introduced from the supply pipe 36 into the chiller 16 via the second outlet. For example, a duct element 38 is fluidically connected with both the chiller 16 and the second outlet such that, by the duct element 38, the fluid may be guided from the supply pipe 36 to the second outlet and via the second outlet into the chiller 16 thereby supplying the chiller 16 with the fluid. Furthermore, the supply pipe 36 comprises a third outlet 40 by which a surge tank of the thermal circuit 10 is fluidically connected with the supply pipe 36 such that the fluid may be introduced from the supply pipe 36 into the surge tank via the third outlet 40. Thus, the thermal circuit 10 comprises said surge tank. Moreover, the supply pipe 36 comprises a fourth outlet 42 by which the heating device 22 is fluidically connected with the supply pipe 36 such that the fluid may be introduced from the supply pipe 36 into the heating device 22 via the fourth outlet 42. As shown in Fig. 1, a duct element 44 is fluidically connected with both the outlet 42 and the heating device 22 such that, by the duct element 44, the fluid may be guided from the supply pipe 36 to the heating device 22 thereby supplying the heating device 22 with the fluid.
[0024] The thermal circuit 10 further comprises a valve 46 which is configured as a 3/2 valve in the embodiment shown in the figures. In this regard, the supply pipe 36 comprises a fourth inlet 48 by which the valve 46 is fluidically connected with the supply pipe 36 such that the fluid may be introduced from the valve 46 into the supply pipe 36 via the fourth inlet 48 thereby supplying the supply pipe 36 with the fluid. The second outlet, the third outlet 40, the fourth outlet 42 and the fourth inlet 48 are arranged in series along the supply pipe, in particular along a flowing direction in which the fluid flows through the supply pipe 36 (i.e., the fluid is conveyed through the supply pipe 36 by the pump 34).
[0025] Moreover, the manifold 12 comprises a bypass 50 which is fluidically connected with the delivery pipe 14 and the supply pipe 36 such that the fluid may be introduced from the supply pipe 36 into the delivery pipe 14 via the bypass 50 thereby bypassing the chiller 16, the heating device 22 and the surge tank.
[0026] As shown in Fig. 1, the pump 34 has a pump outlet 52 by which a duct element 54 is fluidically connected with the pump 34. Moreover, the duct element 54 is at least indirectly fluidically connected with the battery such that the battery may be supplied with the fluid conveyed by the pump 34 via the duct element 54. In other words, the duct element 54 is configured to guide the fluid conveyed by the pump 34 from the pump 34 to the battery. Moreover, the valve 46 comprises a first valve inlet 56 via which the fluid coming from or flowing away from the battery may be introduced into the valve 46. As shown in Fig. 1, a duct element 58 may be fluidically connected with both the valve inlet 56 and the battery such that the fluid may be guided from the battery to the valve 46 by or via the duct element 58. Moreover, the valve 46 has a valve outlet 60 via which the fluid may be guided from the valve 46 to said radiator. For example, a duct element 62 is fluidically connected with both the valve outlet 60 and the radiator such that, by the duct element 62, the fluid may be guided from the valve 46 to the radiator. In other words, the radiator may be supplied with the fluid from the valve 46 via or by the duct element 62.
[0027] In the embodiment shown in the figures, the delivery pipe 14 and the supply pipe 36 are configured as separately manufactured components, wherein the delivery and supply pipes 14 and 36 are mechanically connected with each other thereby forming, for example, an assembly or an assembled module which may be handled and installed in a particularly easy way. Moreover, at least respective length areas L-1 and L2 of the delivery pipe 14 and the supply pipe 36 extend parallel to each other.
[0028] Preferably, the manifold 12 comprises fastening elements 74 which are at least indirectly connected with the delivery pipe 14 and/or the supply pipe 36. By the fastening elements 74, the manifold 12 may be connected with a component of the vehicle. For example, the fastening elements 74 may be screwed and/or welded to said components, thereby attaching the manifold 12 to said component. Particularly, the fastening elements 74 are configured to be directly used on the component and thus the vehicle. For example, the respective fastening element 74 is configured as a weldment.
[0029] As shown in Fig. 1, the delivery pipe 14 comprises a fifth inlet 64 by which the surge tank is fluidically connected with the delivery pipe 14 such that the fluid may be introduced from the surge tank into the delivery pipe 14 via the fifth inlet 64. The first inlet 18, the second inlet 26, the third inlet, the fifth inlet 64 and the first outlet 32 are arranged in series along the delivery pipe 14 (i.e., along said flowing direction in which the fluid flows or is conveyed through the delivery pipe 14).
[0030] In the embodiment shown in the figures, the thermal circuit 10 comprises the heating device 24. In this regard, the delivery pipe 14 comprises a sixth inlet 66 by which the heating device 24 for electrically heating the fluid is fluidically connected with the delivery pipe 14 such that the fluid may be introduced from the heating device 24 into the delivery pipe 14 via the sixth inlet 66. In this regard, a duct element 68 is fluidically connected with both the sixth inlet 66 and the heating device 24 such that the fluid may be guided from the heating device 24 to the inlet 66 and via the inlet 66 into the delivery pipe 14 by or via the duct element 68. Furthermore, the supply pipe 36 comprises a fifth outlet 70 by which the heating device 22 is fluidically connected with the supply pipe 36 such that the fluid may be introduced from the supply pipe into the heating device 24 via the outlet 70. As shown in Fig. 1, a duct element 72 is fluidically connected with both the outlet 70 and the heating device 24 such that the fluid may be guided from the supply pipe 36 to the heating device 24 by the duct element 72. In other words, the heating device 24 may be supplied with the fluid from the supply pipe 36 via the duct element 72. In the embodiment shown in the figures, the bypass 50 is fluidically connected with the delivery pipe 14 at a first connection point P1. Moreover, the bypass 50 is fluidically connected with the supply pipe 36 at a second connection point P2. With respect to the flowing direction of the fluid flowing through the delivery pipe 14, in particular when conveyed by the pump 34, the connection point P1 is arranged downstream of the inlet 26 and upstream of the inlet 66. Moreover, with respect to the flowing direction of the fluid flowing through the supply pipe 36, in particular when conveyed by the pump 34, the connection point P2 is arranged downstream of the outlet 70 and upstream of the outlet 42. The bypass 50 is an integrated bypass by which the fluid may be guided in a particularly advantageous way. By the manifold 12, the chiller 16, the heating devices 22 and 24 and the bypass 50 are connected or arranged in parallel connection along with the pump 34, the valve 46, the surge tank and the radiator are arranged or connected in series connection, in particular in such a way that, for example, the pump 34 and the valve 46 are arranged in series connection with respect to each other, wherein, for example, the radiator and the second receptacle are arranged in series connection with respect to the valve 46 and, for example, wherein the surge tank and the radiator are arranged in parallel connection with respect to each other such that, for example, the surge tank is arranged or connected in series connection with the pump 34 and/or the radiator is arranged or connected in series connection with respect to the pump 34. The manifold 12 has a design by which said connections may be realized in a particularly easy way, wherein the fluid may flow through the manifold 12 in a particularly advantageous way. In particular, the manifold 12 itself may be realized without any mechanical or movable part so that a chance of part failure may be kept particularly low. In the embodiment shown in the figures the supply and delivery pipes 36 and 14 are joined together by the bypass 50 at a particularly advantageous location to allow a particularly effective flow of the fluid. Moreover, said duct elements are used as inlet and outlet pipes which are placed or arranged tangentially to the delivery and supply pipes 14 and 36 in order to maximize a volume of the fluid and minimize a change of air pockets in the thermal circuit 10.
