Description

[0001] The invention relates to a component module for a heat pump system of a vehicle, in particular for a heat pump system of a battery-electric vehicle. 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 the preferred choice for battery electric vehicles (BEVs). Heat pumps are used to regulate the temperature of the vehicle interior and the vehicle batteries. Regulating the temperature of the vehicle batteries ensures optimal operating conditions, which leads to improved performance and extends the service life of the vehicle batteries. This is important for increasing the range and reliability of battery electric vehicles. Regulating the temperature involves changing the temperature either for heating or cooling, with the heat pump being able to utilize various heat sources and heat sinks in different fluid circuits. For example, starting up a BEV at low outside temperatures first requires heating 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 prevent overheating due to heat generation. The heat generated in the batteries can be dissipated to the environment via coolant circuits or to heat the vehicle interior.

[0003] A heat pump system comprises various components fluidically interconnected in a refrigerant circuit. These typically include a compressor for compressing a refrigerant, a first heat exchanger acting as an evaporator, a second heat exchanger acting as a condenser, and an expansion device for varying the pressure of a circulating refrigerant. The heat pump system utilizes the principle of evaporation and condensation of the refrigerant, with heat being transferred between the refrigerant and another fluid, such as a coolant in a separate coolant circuit, in 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 high 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 to one another in a common module. An example of such an arrangement can be found in the teaching EP 4 144 549 A1. The heating and / or cooling module described therein comprises as components 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 fluidically connected to one another in such a way that a refrigerant can circulate.The arrangement of the components is oriented along a spatial axis system consisting of an L-direction, a T-direction orthogonal to the L-direction, and a V-direction orthogonal to the L- and T-directions. The heat exchanger extends with its longest body size or body length parallel to the L-direction, while the compressor extends with its longest body side, which corresponds to the orientation of the compressor's rotation axis, essentially along the T-direction and is thus oriented orthogonally to the heat exchanger. This arrangement enables a space-saving configuration of the components - but requires more installation space in the LV plane spanned by the L- and V-directions, particularly in the L-direction.This arrangement of components requires that the connecting lines, such as the refrigerant line between the compressor and the heat exchanger, partially extend across the entire LV level due to their design, partially obstructing access to other cooling or refrigerant lines as well as electrical connectors. Furthermore, the expansion of the arrangement in the LV level requires additional mounting brackets, as the heat exchanger must be supported relative to the compressor, which involves additional costs and increases the module weight.

[0005] Patent application number US 2019 / 0 039 440 A1 describes a plate-shaped fluid distribution device for vehicles. The fluid distribution device forms a compact arrangement of fluidically interconnected vehicle components such as compressors, condensers, chillers, or coolant reservoirs. The application describes various embodiments in which the distributor, for example, has a main surface to which motors, sensors, or valves are attached. The distributor can be T-shaped in cross-sectional view or consist of several stacked plates.

[0006] Another compact component arrangement for a vehicle is known from DE 10 2023 118 683 A1. However, the known solutions for compact arrangements are associated with functional limitations.

[0007] Against this background, the invention is based on the object 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.

[0008] The object is achieved by a refrigerant module having the features according to patent claim 1. Further developments are specified in the dependent patent claims.

[0009] 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 has at least the following components: a compressor for compressing a refrigerant, wherein the compressor is accommodated in a compressor housing whose body length extends along a compressor rotation axis. The component arrangement has a first heat exchanger and a second heat exchanger as further components. The heat exchangers are designed to transfer heat between a refrigerant and a coolant and have a body length greater than a body width. Furthermore, a collecting container for refrigerant is provided in order to store the refrigerant at least partially in liquid form over the course of the refrigerant circuit.A fluid distribution device is provided as a further component, which is configured to influence a refrigerant flow path. The components have fluid interfaces for refrigerant and / or coolant, as well as fluid lines with which the components are fluidly connected to one another. In the following, fluid lines for refrigerants are referred to as refrigerant fluid lines. Likewise, fluid interfaces for refrigerants or coolants are referred to as refrigerant fluid interfaces or coolant fluid interfaces.

[0010] According to the invention, the components are oriented in their arrangement within the component module as follows: The first heat exchanger is oriented with its body length along a first main direction, wherein the second heat exchanger is oriented with its body length orthogonal to the first main 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, wherein an air gap is present between the first heat exchanger and the second heat exchanger in order to avoid a thermal bridge. The compressor housing is oriented with its body length along a second main direction, which coincides with the compressor rotation axis and is parallel to the first main direction, offset in a longitudinal direction.As a result, the first heat exchanger and the compressor housing are arranged parallel to each other with their body lengths, which reduces the expansion of the component module in the longitudinal direction oriented transversely to the main directions.

[0011] According to the concept of the invention, the two parallel main directions, the longitudinal direction and the vertical direction, relate to spatial axes, of which the two main directions and the longitudinal direction oriented perpendicular to the two main directions can lie in one plane, with the vertical axis being oriented perpendicularly with respect to the plane formed by the two main directions and the longitudinal direction. According to a further embodiment, one of the two main directions and the longitudinal direction form a plane, with the other main direction being shifted in the direction of the vertical axis.

[0012] According to a preferred embodiment, the heat exchangers are essentially designed in the shape of a cuboid, which has a body length greater than a body width. The cuboid shape can have two different body widths, each of which is smaller than the body length.

[0013] The spatial extension of the component module in the first main direction is achieved by arranging the second heat exchanger with its body length oriented in the direction of the vertical axis. Thus, the first heat exchanger and the second heat exchanger can be arranged next to one another along the first main direction without significantly exceeding the spatial extension of the body length of the compressor housing. However, the heat exchangers are preferably dimensioned such that, when arranged next to one another along the first main direction, they do not exceed the spatial extension of the body length of the compressor housing.

[0014] 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 space. 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 concept 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 space.

[0015] Within the component module, a fastening of the first heat exchanger and / or the second heat exchanger to the compressor housing can be provided. Furthermore, the first heat exchanger can be fastened to the second heat exchanger, in which case the second heat exchanger is fastened to the compressor housing. Preferably, the first heat exchanger is firmly screwed to the compressor housing.

[0016] 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 enable different flow paths for refrigerant and thus different operating modes for temperature control. While designs with two valves serve as expansion valves, designs with three or four valves can implement additional operating modes, such as (inefficient) boost heating operation.

[0017] The valve block of the fluid distribution device and the first heat exchanger can be connected to one another in such a way that the first heat exchanger and the valve block of the fluid distribution device form a fluidic connection for the refrigerant, without the need for external refrigerant fluid lines between the first heat exchanger and the valve block of the fluid distribution device. In this case, the fluidic connection for the refrigerant is provided by corresponding refrigerant fluid interfaces formed in the housing of the opposing components. For this purpose, the first heat exchanger and the valve block of the fluid distribution device can be contacted with one another on mutually facing sides in such a way that no external fluid lines are required between the first heat exchanger and the valve block.The corresponding openings of opposing refrigerant-fluid interfaces thus enable refrigerant flow from the valve block of the fluid distribution device into the first heat exchanger. To prevent leaks, seals, such as a face seal, can be arranged between the valve block of the fluid distribution device and the first heat exchanger.

[0018] An air gap may be formed between the compressor housing and the second heat exchanger to avoid a thermal bridge.

[0019] Fastening the components with and to the compressor housing is preferred because the compressor housing has a high rigidity and a sufficient material volume to form threaded holes into which fastening screws can be screwed to fasten the other components.

[0020] In the configuration according to the invention, the component module is intended in particular for battery electric vehicles (BEVs), since it is designed for heating and / or cooling.

[0021] According to an embodiment not belonging to the invention, the first heat exchanger and the second heat exchanger are fluidically connected to one another such that the first heat exchanger is configured as an evaporator (chiller) for refrigerant, wherein the second heat exchanger is configured as a condenser for refrigerant. According to the invention, the second heat exchanger is designed as a combination of condenser and internal heat exchanger (IWT) and can thus be used for different operating modes. In this regard, a refrigerant fluid line can be formed 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 internal heat exchanger.

[0022] Both heat exchangers are designed to transfer heat between a refrigerant and a coolant. The fluidic connection between the heat exchangers enables heating and / or cooling operation, making the component module suitable for heating and / or cooling. The first heat exchanger and the second heat exchanger are thus directly fluidically connected to each other.

[0023] Following the concept of a space-saving arrangement, the fluid distribution device, which is designed to influence the flow paths of the refrigerant within the component module, can preferably be attached to the compressor housing along the body length of the compressor housing next to the second heat exchanger in such a way that it does not protrude beyond the body length of the second heat exchanger in the vertical direction. The installation space height of the fluid distribution device is thus advantageously at the same height or below the spatial extent of the body length of the second heat exchanger when it is attached to the compressor housing. In the longitudinal direction, an air gap can be formed between the fluid distribution device and the second heat exchanger, which prevents direct contact between these components. For attachment, the fluid distribution device can be screwed to the compressor housing.

[0024] The refrigerant collection tank is designed to store refrigerant in liquid form. Its body length, which preferably has a circular cylindrical shape, can be greater than a body width, wherein the collection tank is arranged next to the second heat exchanger with its body length oriented parallel to the vertical direction. Preferably, the collection tank is arranged along the first main direction next to the second heat exchanger, so that the second heat exchanger is located between the collection tank and the first heat exchanger along the first main direction. The collection tank can be dimensioned such that it does not protrude beyond the second heat exchanger in the vertical direction.

[0025] 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 a body width, wherein, according to one embodiment of the component module, the muffler can be oriented with its body length essentially parallel to the longitudinal direction within the arrangement in the component module next to the collecting tank. In this orientation, the muffler is arranged transversely to the collecting tank, offset in the direction of the main directions with respect to the collecting tank. The body length of the muffler is preferably dimensioned such that it does not protrude beyond the other components of the component module arranged next to one another in the longitudinal direction. Due to its relatively small dimensions, the muffler can also be arranged in other positions of the component module in a space-saving manner.

[0026] The component module has fluid interfaces as fluid connections for connection to 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 toward one side of the component module. Advantageously, all coolant fluid interfaces are thus accessible from one side of the component module.

[0027] According to a particularly preferred embodiment, the second heat exchanger in the arrangement in the component module has an inner side and an outer side, wherein at least one refrigerant fluid interface is formed on the inner side oriented parallel to the first main direction. A refrigerant fluid line connecting the compressor housing and the second heat exchanger can be connected to the 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 protrude beyond the second heat exchanger in the vertical direction. As a result, the refrigerant fluid lines are protected and arranged with little installation space requirement. The inner side of the second heat exchanger faces an inner side of the oppositely arranged first heat exchanger.The heat exchangers arranged next to one another along the first main direction thus have oppositely facing inner sides, between which an air gap is formed.

[0028] On its outer side opposite the inner side, the second heat exchanger can also have refrigerant fluid interfaces, wherein the refrigerant fluid interfaces formed on the outside can be oriented parallel to the first main direction.

[0029] The component module according to the invention realizes an even more compact arrangement of components of a heat pump system, thus advantageously achieving an even further reduction in installation space. Because the components are fastened to one another, the component module is given sufficient stability and rigidity without the need for additional mounting brackets or node elements. This contributes to a reduction in weight and ultimately to a reduction in costs.

[0030] 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. They show: Fig. 1: a schematic perspective view of an embodiment of the component module for a heat pump system of a vehicle, and Fig. 2: a top view of the Fig. 1 shown embodiment of the component module for a heat pump system of a vehicle.

[0031] In the figures, recurring features of the component module for a heat pump system of a vehicle are identified by the same reference numerals.

[0032] The Fig. 1 shows a schematic perspective view of an exemplary embodiment of the component module 1 for a heat pump system of a vehicle. As components, the component module 1 comprises a compressor for compressing a refrigerant, wherein the compressor is accommodated in a compressor housing 2, the body length of which extends along a compressor rotation axis R. As further components, the component module 1 has a first heat exchanger 3 and a second heat exchanger 4. Both heat exchangers 3 and 4 have a cuboid shape with a body length greater than a body width. The cuboid shape can have two different body widths, each of which is smaller than the body length.

[0033] The first heat exchanger 3 is oriented with its body length along a first main direction T1, wherein the second heat exchanger 4 is oriented with its body length orthogonal to the first main 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, wherein an air gap is present between the first heat exchanger 3 and the second heat exchanger 4. The first heat exchanger 3 is designed to transfer 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 visible in the illustration shown. This is designated by the 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 for fluid connection to a refrigerant fluid interface 4.4 of the second heat exchanger 4. According to an advantageous embodiment, the refrigerant fluid line 8.1 is designed as an integral component of the first heat exchanger 3, without projecting beyond the dimensions of the first heat exchanger 3 to an outer side of the component module 1. The refrigerant fluid interface 4.4 is formed on an inner side 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 screwed together.

[0034] The second refrigerant fluid interface of the first heat exchanger 3 is located on a side facing the compressor housing 2, on which side the first heat exchanger 3 is advantageously screwed 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 with its body length along a second main direction T2, which coincides with the compressor rotation axis R and is offset in a longitudinal direction L and parallel to the first main direction T1. The second refrigerant fluid interface of the first heat exchanger 3 leads directly into the valve block 6.1 by means of a refrigerant fluid line.

[0035] A refrigerant fluid line 8.2 leads from the compressor housing 2 to a further refrigerant fluid interface 4.3 formed on the inner side 11 of the second heat exchanger 4. 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.

[0036] The refrigerant fluid lines 8.1 and 8.2 are rigid. Optionally, the refrigerant fluid line 8.2 can be designed to be flexible in some areas. By screwing the refrigerant fluid lines 8.1 and 8.2 to the refrigerant fluid interfaces 4.4 and 4.3, the second heat exchanger 4 is secured in the arrangement of the component module 1. In addition, a component module holder 14 is provided, to which the second heat exchanger 4 is secured, wherein the component module holder 14 is screwed to the compressor housing 2. Optionally, a further screw connection of the second heat exchanger 4 to the first heat exchanger 3 and / or the compressor housing 2 can be provided.

[0037] Further refrigerant fluid interfaces 4.5 and 4.6 are formed on an outer side 12 of the second heat exchanger. These further refrigerant fluid interfaces 4.5 and 4.6 are also oriented parallel to the first main direction T1.

[0038] Furthermore, the second heat exchanger 4 has two coolant fluid interfaces 4.1 and 4.2 to enable integration of the second heat exchanger 4 into a coolant circuit. The coolant fluid interfaces 4.1 and 4.2 are oriented toward an outer side of the component module 1. Thus, the coolant fluid interfaces 3.1 and 3.2 of the first heat exchanger 3 and the coolant fluid interfaces 4.1 and 4.2 of the second heat exchanger 4 are accessible from one side of the component module 1.

[0039] 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. According to the invention, the second heat exchanger 4 is designed as a combined heat exchanger with the function of a condenser and the function of an internal heat exchanger.

[0040] As a further component, the component module 1 has 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. For attachment, threaded holes (concealed) are formed on the circumference of the compressor housing 2. In the illustrated embodiment, the fluid distribution device 6 comprises a valve block 6.1 (see Fig. 2) with four valves 6.2.1 to 6.2.4, which are oriented in the valve block 6.1 parallel to the vertical axis V. 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 overall height of the fluid distribution device 6 ends with 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 connection to the compressor or compressor housing 2 on the refrigerant side, so that no additional external refrigerant fluid lines are required.

[0041] A collecting tank 5 for refrigerant also forms a component of the component module 1. Fluidically connected to the second heat exchanger 4, the collecting tank 5 is designed to store refrigerant in liquid form. Its body length, which has a circular cylindrical shape, is greater than its body diameter, wherein the collecting tank 5 is arranged next to the second heat exchanger 4 with its body length oriented parallel to the vertical direction V. Since the body length of the collecting tank 5 and the body length of the second heat exchanger 4 are oriented parallel, the collecting tank 5 is thus oriented transversely to the first main direction T1 and consequently transversely to the body length of the first heat exchanger 3.In the exemplary embodiment shown, the collecting container 5 is thus arranged along the first main direction T1 transversely thereto next to the second heat exchanger 4, so that the second heat exchanger 4 is arranged along the first main direction T1 in an arrangement between the collecting container 5 and the first heat exchanger 3. The collecting container 5 is dimensioned such that it does not protrude beyond the second heat exchanger 4 in the vertical direction V.

[0042] To reduce noise, a muffler 7 is provided as a further component of the component module 1. The muffler 7 is designed as a component of a refrigerant fluid line 8.3 that is fluidically connected to the valve block 6.1 and has a body length greater than a body width. Within the component module 1, the muffler 7 is oriented next to the collecting tank 5 with its body length essentially parallel to the longitudinal direction L. In this orientation, the muffler 7 is arranged transversely to the collecting tank 5, offset in the direction of the main directions T1 and T2 with respect to the collecting tank 5. The body length of the muffler 7 is dimensioned such that it does not protrude 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 of the component module 1 in a space-saving manner.For the fluidic connection, the muffler 7 has a refrigerant fluid interface 7.1, the opening of which is oriented parallel to the longitudinal direction L.

[0043] A further 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 relation to the refrigerant fluid interface 7.1 of the muffler 7 in a direction parallel to the vertical direction V, wherein the opening of the refrigerant fluid line 8.4 is oriented parallel to the longitudinal direction L.

[0044] The spatial extent of the component module 1 is limited in the two main 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 the component module 1 is limited by a body length of the compressor housing 2 and on the opposite side by the first heat exchanger 3. The spatial extent of the component module 1 in the vertical direction V is limited by the second heat exchanger 4.

[0045] The reference numerals 9.1 to 9.4 indicate electrical interfaces of component module 1.

[0046] The Fig. The embodiment shown in Figure 1 is intended in particular for battery-electric vehicles.

[0047] The Fig. 2 shows a top view of the Fig.1 of the exemplary embodiment of the component module 1 for a heat pump system of a vehicle in the vertical direction V. The top view illustrates the positions of the arrangement of the individual components of the component module 1. The arrangement of the second heat exchanger 4 in relation to the compressor housing 2 and the fluid distribution device 6 forms an intermediate space or air gap. A further refrigerant line 8.5 can be seen here, which connects the second heat exchanger 4 to the valve block 6.1.
