Description

[0001] The invention relates to a component module for a vehicle's heat pump system, in particular for a battery-electric vehicle's heat pump system. The component module comprises several components of a heat pump system and is suitable for heating and / or cooling.

[0002] Heat pumps offer an efficient method for transferring thermal energy, which is why they are preferred in battery electric vehicles (BEVs). Heat pumps serve both to regulate the temperature of the vehicle interior and to regulate the temperature of the vehicle batteries. Regulating the battery temperature ensures optimal operating conditions, leading to improved performance and extended battery life. This is crucial for increasing the range and reliability of battery electric vehicles. Regulating the temperature involves either heating or cooling, and the heat pump can utilize various heat sources and heat sinks in different fluid circuits. For example, starting a BEV at low ambient temperatures requires first warming the vehicle batteries, with ambient air serving as the heat source.During electrical charging and discharging, however, cooling of the vehicle batteries may be necessary to counteract overheating due to heat generation. The heat generated in the batteries can be dissipated to the environment or used to heat the vehicle interior via coolant circuits.

[0003] A heat pump system comprises various components fluidly connected within a refrigerant circuit. These typically include a compressor for compressing the refrigerant, a primary heat exchanger acting as an evaporator, a secondary heat exchanger acting as a condenser, and an expansion device to change the pressure of the circulating refrigerant. The heat pump system utilizes the principle of refrigerant evaporation and condensation, whereby heat is transferred between the refrigerant and another fluid, such as a coolant in a separate coolant circuit, within the heat exchangers. The coolant then serves to transport the heat to the desired location in or on the vehicle.

[0004] In the past, the large space requirements of heat pump systems often conflicted with the arrangement of other vehicle components. This prompted further developments towards more compact component arrangements, in which several components of the heat pump system are fluidically connected within a common module. An example of such an arrangement is described in EP 4 144 549 A1. The heating and / or cooling module described therein comprises a compressor with a heat exchanger for heat transfer between a refrigerant and a coolant, as well as a storage device for storing refrigerant. The individual components are fluidly connected in such a way that a refrigerant can circulate.The components are arranged along a spatial axis system consisting of an L-direction, a T-direction orthogonal to the L-direction, and a V-direction orthogonal to both the L- and T-directions. The heat exchanger extends parallel to the L-direction with its longest dimension, or length, while the compressor extends essentially along the T-direction with its longest side, corresponding to the orientation of its axis of rotation, and is thus orthogonal to the heat exchanger. This arrangement allows for a space-saving configuration of the components but results in an increased installation space requirement in the LV plane spanned by the L- and V-directions, particularly in the L-direction.This component arrangement necessitates that connecting lines, such as the refrigerant line between the compressor and the heat exchanger, extend across the entire LV level due to the design. This partially obstructs access to other cooling or refrigerant lines, as well as electrical connectors. Furthermore, the extended arrangement within the LV level requires additional supports, as the heat exchanger must be braced against the compressor. This entails additional costs and increases the module weight.

[0005] Against this background, the invention is based on the objective of proposing a component module for a heat pump system of a motor vehicle / BEV which requires an even smaller installation space volume for the arrangement of the various components and ensures better accessibility to refrigerant and coolant fluid lines as well as electrical connection devices.

[0006] The problem is solved by a refrigerant module with the features according to claim 1. Further developments are specified in the dependent claims.

[0007] A space-saving spatial arrangement of components of a heat pump system within a component module is proposed. The component module according to the invention comprises at least the following components: a compressor for compressing a refrigerant, wherein the compressor is housed in a compressor casing whose length extends along a compressor rotation axis. The component arrangement also includes a first heat exchanger and a second heat exchanger. The heat exchangers are designed for transferring heat between a refrigerant and a coolant and have a length greater than their width. Furthermore, a refrigerant storage tank is provided to store at least part of the refrigerant in liquid form during the refrigerant cycle.A further component is a fluid distribution system designed to influence the refrigerant flow path. The components have fluid interfaces for refrigerants and / or coolants, as well as fluid lines that connect them fluidically. In the following, fluid lines for refrigerants are referred to as refrigerant fluid lines. Similarly, fluid interfaces for refrigerants or coolants are referred to as refrigerant fluid interfaces or coolant fluid interfaces.

[0008] According to the invention, the components are arranged within the component module as follows: The first heat exchanger is oriented with its body length along a first principal direction, while the second heat exchanger is oriented with its body length orthogonal to the first principal direction along a vertical direction. The body length of the first heat exchanger thus extends perpendicular to the body length of the second heat exchanger, with an air gap between the first and second heat exchangers to prevent thermal bridging. The compressor housing is oriented with its body length along a second principal direction, which coincides with the compressor's axis of rotation and is parallel to the first principal direction but offset in a longitudinal direction.This results in the first heat exchanger and the compressor housing being arranged parallel to each other with their body lengths, which reduces the expansion of the component module in the longitudinal direction oriented transverse to the main directions.

[0009] According to the invention, the two parallel principal directions, the longitudinal direction and the vertical direction, are spatial axes, of which the two principal directions and the longitudinal direction oriented perpendicular to the two principal directions can lie in a plane, the vertical axis being oriented perpendicular to the plane formed by the two principal directions and the longitudinal direction. According to a further embodiment, one of the two principal directions and the longitudinal direction form a plane, with the other principal direction being shifted in the direction of the vertical axis.

[0010] According to a preferred embodiment, the heat exchangers are essentially in the form of a cuboid, the length of which is greater than the width. The cuboid shape can have two different widths, each of which is smaller than the length.

[0011] The spatial extent of the component module in the first principal orientation is achieved by arranging the second heat exchanger with its body length oriented along the vertical axis. Thus, the first and second heat exchangers can be arranged side by side along the first principal direction without significantly exceeding the length of the compressor housing. Preferably, however, the heat exchangers are dimensioned such that, when arranged side by side along the first principal direction, they do not exceed the length of the compressor housing.

[0012] The arrangement of the components of the component module according to the invention is conceptually based on a uniform expansion in the available spatial directions, with the aim of achieving the smallest possible installation volume. The components are advantageously arranged within the component module with their body lengths such that the spatial expansion of the component module in the relevant spatial directions is minimal. This design avoids a spatial expansion, as described in the prior art, which is significantly larger in a single spatial direction compared to the expansion in other spatial directions, thereby advantageously reducing the required installation volume.

[0013] Within the component module, the first heat exchanger and / or the second heat exchanger can be attached to the compressor housing. Alternatively, the first heat exchanger can be attached to the second heat exchanger, in which case the second heat exchanger is attached to the compressor housing. Preferably, the first heat exchanger is bolted securely to the compressor housing.

[0014] The fluid distribution device can have a valve block with at least two, preferably three, and particularly preferably four valves, wherein the valves in the valve block are oriented parallel to the vertical direction. The valves allow for different flow paths for refrigerants and thus different operating modes for temperature control. While in configurations with two valves these serve as expansion valves, configurations with three or four valves can implement further operating modes, such as an (inefficient) boost heating mode.

[0015] The valve block of the fluid distribution system and the first heat exchanger can be connected in such a way that they form a fluid flow connection for the refrigerant, eliminating the need for external refrigerant lines between the first heat exchanger and the valve block. In this case, the fluid flow connection is provided by corresponding refrigerant interfaces formed in the housings of the opposing components. For this purpose, the first heat exchanger and the valve block can be contacted on their facing sides in such a way that no external fluid lines are required between them.The corresponding openings of opposing refrigerant fluid interfaces thus allow refrigerant to flow from the valve block of the fluid distribution unit into the first heat exchanger. To prevent leaks, seals, such as a surface gasket, can be installed between the valve block of the fluid distribution unit and the first heat exchanger.

[0016] An air gap can be formed between the compressor housing and the second heat exchanger to avoid a thermal bridge.

[0017] Attaching the components to and with the compressor housing is preferred, because the compressor housing has high rigidity and sufficient material volume to form threaded holes into which fastening screws can be screwed to attach the other components.

[0018] In the configuration according to the invention, the component module is particularly intended for battery electric vehicles (BEVs), as it is designed for heating and / or cooling.

[0019] According to a preferred embodiment of the component module according to the invention, the first heat exchanger and the second heat exchanger are fluidically connected such that the first heat exchanger is configured as an evaporator (chiller) for refrigerant, and the second heat exchanger is configured as a condenser for refrigerant. The second heat exchanger can be designed as a combination of a condenser and an internal heat exchanger (IHE) and can thus be used for different operating modes. In this regard, a refrigerant fluid line can be provided between the second heat exchanger and the valve block of the fluid distribution device. An internal heat exchanger refers to the function of a refrigerant circuit within an internal heat exchanger.

[0020] Both heat exchangers are suitable for transferring heat between a refrigerant and a coolant. The fluid-flow connection between the heat exchangers enables heating and / or cooling operation, making the component module suitable for both heating and / or cooling. The first and second heat exchangers are thus directly connected fluid-wise.

[0021] Following the concept of space-saving arrangement, the fluid distribution device, which is designed to influence the refrigerant flow paths within the component module, can preferably be attached to the compressor housing along its length, next to the second heat exchanger, such that it does not extend beyond the length of the second heat exchanger in the vertical direction. The installation height of the fluid distribution device is thus advantageously at the same height as, or below, the length of, the second heat exchanger when attached to the compressor housing. An air gap can be formed between the fluid distribution device and the second heat exchanger in the longitudinal direction, preventing direct contact between these components. The fluid distribution device can be bolted to the compressor housing for mounting.

[0022] The refrigerant receiver is designed to store refrigerant in liquid form. Its length, which preferably has a circular cylindrical shape, can be greater than its width. The receiver is positioned next to the second heat exchanger with its length oriented parallel to the vertical direction. Preferably, the receiver is positioned next to the second heat exchanger along the first principal direction, such that the second heat exchanger is located between the receiver and the first heat exchanger along the first principal direction. The receiver can be dimensioned so that it does not extend beyond the second heat exchanger in the vertical direction.

[0023] To reduce noise, a muffler can be provided as an additional component along the refrigerant circuit of the component module. The muffler can have a body length greater than its body width, and according to one embodiment of the component module, its body length can be oriented essentially parallel to the longitudinal direction within the component module next to the receiver. In this orientation, the muffler is offset from the receiver in the direction of the main directions and arranged transversely to the receiver. Preferably, the muffler's body length is dimensioned such that it does not extend beyond the other components of the component module arranged side by side in the longitudinal direction. Due to its relatively small dimensions, the muffler can also be arranged in other space-saving positions within the component module.

[0024] The component module features fluid interfaces as fluid connections for integration into a coolant circuit and further fluid interfaces as fluid connections for a refrigerant circuit. According to a preferred embodiment of the component module, all coolant fluid interfaces are located on one side of the component module. This means that the coolant connections of the first heat exchanger and the second heat exchanger are oriented towards one side of the component module. Advantageously, all coolant fluid interfaces are accessible from one side of the component module.

[0025] According to a particularly preferred embodiment, the second heat exchanger in the component module has an inner and an outer surface, with at least one refrigerant fluid interface on the inner surface oriented parallel to the first main direction. A refrigerant fluid line connecting the compressor housing and the second heat exchanger can be connected to this at least one refrigerant fluid interface. This has the advantage that the refrigerant fluid line can be connected parallel to the first main direction and thus does not extend beyond the second heat exchanger vertically. This protects the refrigerant fluid lines and allows for a compact installation. The inner surface of the second heat exchanger faces the inner surface of the first heat exchanger, which is arranged opposite it.The heat exchangers arranged side by side along the first main direction thus have opposing inner surfaces, between which an air gap is formed.

[0026] On its outer side opposite the inner side, the second heat exchanger can also have refrigerant fluid interfaces, whereby the refrigerant fluid interfaces formed on the outside can be oriented parallel to the first main direction.

[0027] The component module according to the invention enables an even more compact arrangement of components for a heat pump system, thus advantageously achieving a further reduction in installation volume. Because the components are attached to each other, the component module is given sufficient stability and rigidity without the need for additional supports or node elements. This contributes to a reduction in weight and ultimately to a reduction in costs.

[0028] Further details, features, and advantages of embodiments of the invention will become apparent from the following description of exemplary embodiments with reference to the accompanying drawings. These show: Fig. 1: A schematic perspective view of an exemplary embodiment of the component module for a vehicle heat pump system, and Fig. 2: a top view of the in Fig. 1 shown embodiment of the component module for a vehicle heat pump system.

[0029] In the figures, recurring features of the component module for a vehicle's heat pump system are marked with the same reference symbols.

[0030] The Fig. Figure 1 shows a schematic perspective view of an embodiment of component module 1 for a vehicle heat pump system. Component assembly 1 comprises a compressor for compressing a refrigerant, the compressor being housed in a compressor casing 2, the length of which extends along a compressor rotation axis R. Component assembly 1 also includes a first heat exchanger 3 and a second heat exchanger 4. Both heat exchangers 3 and 4 are cuboid in shape, with a length greater than a width. The cuboid shape can have two different widths, each of which is smaller than the length.

[0031] The first heat exchanger 3 is oriented with its body length along a first principal direction T1, while the second heat exchanger 4 is oriented with its body length orthogonal to the first principal direction T1 along a vertical direction V. The body length of the first heat exchanger 3 thus extends perpendicular to the body length of the second heat exchanger 4, with an air gap between the first heat exchanger 3 and the second heat exchanger 4. The first heat exchanger 3 is designed for transferring heat between a coolant and a refrigerant and has two coolant fluid interfaces 3.1 and 3.2. The coolant fluid interfaces 3.1 and 3.2 serve as fluid connections for integration into a coolant circuit. For integration into the refrigerant circuit, the first heat exchanger 3 has two refrigerant fluid interfaces, of which only one is shown in the illustration. This is labeled with reference numeral 3.3. A first fluid interface 3.3 for refrigerant of the first heat exchanger 3 leads via a refrigerant fluid line 8.1 to a fluid connection at a refrigerant fluid interface 4.4 of the second heat exchanger 4. According to an advantageous embodiment, the refrigerant fluid line 8.1 is formed as an integral part of the first heat exchanger 3, without projecting beyond the dimensions of the first heat exchanger 3 to any outer surface of the component module 1. The refrigerant fluid interface 4.4 is formed on an inner surface 11 of the second heat exchanger 4 and is oriented parallel to the first main direction T1. The fluid interfaces 3.3 and 4.4 are bolted together.

[0032] The second refrigerant fluid interface of the first heat exchanger 3 is located on a side facing the compressor housing 2, where the first heat exchanger 3 is advantageously bolted to the compressor housing 2 by means of two screws. In the illustrated embodiment, only one of the two screws 10 is visible due to the perspective view. The compressor housing 2 is oriented along a second principal direction T2, which coincides with the compressor rotation axis R and is parallel to the first principal direction T1, offset in a longitudinal direction L. The second refrigerant fluid interface of the first heat exchanger 3 leads directly to the valve block 6.1 via a refrigerant fluid line.

[0033] A refrigerant fluid line 8.2 leads from the compressor housing 2 to a further refrigerant fluid interface 4.3 for refrigerant formed on the inside 11 of the second heat exchanger 4, wherein the refrigerant fluid line 8.2 is screwed to the refrigerant fluid interface 4.3. This further refrigerant fluid interface 4.3, like the refrigerant fluid interface 4.4, is oriented parallel to the main direction T1.

[0034] The refrigerant fluid lines 8.1 and 8.2 are rigid. Optionally, refrigerant fluid line 8.2 can be flexible in certain sections. The second heat exchanger 4 is attached to the component module 1 by screwing the refrigerant fluid lines 8.1 and 8.2 to the refrigerant fluid interfaces 4.4 and 4.3. A component module holder 14 is also provided, to which the second heat exchanger 4 is attached, and the component module holder 14 is screwed to the compressor housing 2. Optionally, the second heat exchanger 4 can also be screwed to the first heat exchanger 3 and / or the compressor housing 2.

[0035] On an outer surface 12 of the second heat exchanger, further refrigerant fluid interfaces 4.5 and 4.6 are formed. These further refrigerant fluid interfaces 4.5 and 4.6 are also oriented parallel to the first main direction T1.

[0036] Furthermore, the second heat exchanger 4 has two coolant fluid interfaces, 4.1 and 4.2, to enable its integration into a coolant circuit. Coolant fluid interfaces 4.1 and 4.2 are oriented towards the outside of component module 1. Thus, coolant fluid interfaces 3.1 and 3.2 of the first heat exchanger 3 and coolant fluid interfaces 4.1 and 4.2 of the second heat exchanger 4 are accessible from one side of component module 1.

[0037] In the illustrated embodiment, the first heat exchanger 3 functions as an evaporator (chiller) for refrigerant, while the second heat exchanger 4 functions as a condenser for compressed refrigerant. Optionally, the second heat exchanger 4 can be configured as a combined heat exchanger with the functions of a condenser and an internal heat exchanger.

[0038] As a further component, the component module 1 includes a fluid distribution device 6 for influencing the flow paths of the refrigerant within the component module 1. The fluid distribution device 6 is attached to the compressor housing 2 along the body length of the compressor housing 2 next to the second heat exchanger 4. Two threaded holes (concealed) are provided on the circumference of the compressor housing for fastening. In the illustrated embodiment, the fluid distribution device 6 comprises a valve block 6.1 (see figure). Fig. 2) with four valves 6.2.1 to 6.2.4, which are oriented parallel to the vertical axis V in the valve block 6.1. The orientation of the valves 6.2.1 to 6.2.4 is thus transverse to the body length of the compressor housing 2 and parallel to the vertical direction V. The height of the fluid distribution unit 6 is equal to the body length of the second heat exchanger 4 in the vertical direction V. The valves 6.2.1 and 6.2.2 serve as expansion valves. The valve block 6.1 has a direct refrigerant connection to the compressor or the compressor housing 2, so that no additional external refrigerant lines are required.

[0039] A refrigerant collection tank 5 also forms a component of component module 1. Fluidically connected to the second heat exchanger 4, the collection tank 5 is designed to store refrigerant in liquid form. Its length, which has a circular cylindrical shape, is greater than its diameter. The collection tank 5 is positioned next to the second heat exchanger 4 with its length oriented parallel to the vertical direction V. Since the length of the collection tank 5 and the length of the second heat exchanger 4 are parallel, the collection tank 5 is thus oriented perpendicular to the first principal direction T1 and consequently perpendicular to the length of the first heat exchanger 3.In the illustrated embodiment, the collection tank 5 is thus arranged transversely to the first principal direction T1 next to the second heat exchanger 4, such that the second heat exchanger 4 is located between the collection tank 5 and the first heat exchanger 3 along the first principal direction T1. The collection tank 5 is dimensioned such that it does not project beyond the second heat exchanger 4 in the vertical direction V.

[0040] To reduce noise, a muffler 7 is provided as an additional component of component module 1. The muffler 7 is designed as part of a refrigerant fluid line 8.3 that is fluidically connected to the valve block 6.1 and has a body length greater than its body width. Within component module 1, the muffler 7 is positioned next to the receiver 5, with its body length oriented essentially parallel to the longitudinal direction L. In this orientation, the muffler 7 is offset from the receiver 5 in the directions T1 and T2 and arranged transversely to the receiver 5. The length of the muffler 7 is dimensioned such that it does not extend beyond the second heat exchanger 4 or the compressor housing 2 in the longitudinal direction L. Due to its relatively small dimensions, the muffler 7 can also be arranged in other positions within component module 1 to save space.For the flow-related connection, the muffler 7 has a refrigerant fluid interface 7.1, the opening of which is oriented parallel to the longitudinal direction L.

[0041] Another refrigerant fluid line 8.4, which is fluidically connected to the valve block 6.1, has a refrigerant fluid interface 13 which is offset in a direction parallel to the vertical direction V with respect to the refrigerant fluid interface 7.1 of the muffler 7, wherein the opening of the refrigerant fluid line 8.4 is oriented parallel to the longitudinal direction L.

[0042] The spatial extent of component module 1 is limited in the two principal directions T1 and T2 on one side by an end face of the compressor housing 2 and on the opposite side by the muffler 7. In the longitudinal direction L, the spatial extent of component module 1 is limited by one length of the compressor housing 2 and on the opposite side by the first heat exchanger 3. The spatial extent of component module 1 in the vertical direction V is limited by the second heat exchanger 4.

[0043] Reference numbers 9.1 to 9.4 identify electrical interfaces of component module 1.

The top view illustrates the positions of the individual components of component module 1. The arrangement of the second heat exchanger 4 in relation to the compressor housing 2 and the fluid distribution unit 6 forms an intermediate space or air gap.
