Description

The invention relates to a tempering module for an electric module, in particular for a battery module or for an electric motor, according to claim 1 or an arrangement of tempering modules according to claim 15.

In addition, the invention relates to a temperature control device comprising a plurality of temperature control modules according to claim 17 and an electric module, in particular battery module or electric motor, with a temperature control module according to the invention as claimed in claim 18.

Furthermore, the invention relates to arrangements of at least two or three electric modules with a tempering module according to the invention or a tempering device according to the invention according to claim 19, claim 20 or claim 21.

Finally, the invention relates to a method for tempering an electric module, in particular a battery module or an electric motor, using a temperature control module according to the invention or a temperature control device according to the invention.

From the EP 3 056 847 A1 It is known to temper a body by means of a device for flowing around the body with a tempering medium. The known device is characterized in that the tempering device comprises at least one wound from a metallic tape wound hose, which winding tube is disposed on a lateral surface of the body and surrounds them at least partially. The winding tube forms inside of its profile a clear, helical flow space for the temperature control medium. Since a winding tube is not fully fluid-tight due to the design, an additional outer tube is provided for sealing.

In the prior art described above has proved to be disadvantageous that - in the case of a cooling application - dissipated heat must pass through walls of the winding tube partially, which wall is formed in sections even double-layered. Due to the required multi-part solution with outer tube results in a relatively high material and cost. In addition, due to the fact that the flow guidance takes place via a single, long flow channel, relatively high pressure losses occur.

In 1 For example, the prior art solution described above is illustrated in the drawings. reference numeral 1 denotes a body to be tempered with surface 1a ; reference numeral L denotes the longitudinal axis of the body. With reference numerals 2 the said winding tube is shown, which consists of a metallic band 2a is wound. reference numeral 3 denotes the said outer tube for sealing. With reference numerals 4 the helical flow space for the temperature control medium is shown.

To counteract the disadvantages mentioned, the temperature control device according to 1 be modified as in 2 shown. Like reference numerals designate here - as in all figures - the same or equivalent elements. For flow guidance for the temperature control is according to 2 one to the body 1 open U-wrap profile 5 used, with adjacent windings spaced from each other in the direction of the longitudinal axis L are arranged. Again, an outer tube 3 needed for sealing, and the fluid guide is helical. The material insert is opposite to the solution in 1 reduced, which means a cost and weight savings. In addition, there are no areas with double wall of the winding tube, which facilitates the heat transfer. However, a disadvantage here too is the multi-part solution due to the presence of an outer tube and the relatively high pressure loss. In addition, it comes in the area between the surface (lateral surface) 1a of the body to be tempered 1 and the free legs of the U-winding profile to a mass flow slip of the tempering, which can adversely affect the tempering.

3 shows the embodiment according to 2 in a perspective view with partially omitted outer tube 3 and a supply line 6 for the tempering medium to the flow space 4 (see 2 ).

To certain disadvantages of the embodiment according to 2 to avoid their subject matter according to 4a be further educated. 4a shows instead of a winding tube or winding profile with outer tube at least in longitudinal sections helically corrugated cooling sleeve 7 , which correspond to a helical flow space 4 provides for a tempering medium. This is found inside (at the top of each flattened) wave mountains 7a while the intervening troughs 7b are formed relatively narrow. Particularly advantageous in the embodiment according to 4a is that this is a one-piece solution, because a sealing outer tube 3 (see 1 to 3 ) is no longer necessary. Due to the flattened wave mountains 7a results in a cylindrical binding geometry, which represents a further advantage. A specific disadvantage may be that the machine production of the cooling sleeve 7 according to 4a is relatively expensive. In addition, the design suffers according to 4a under a similar mass flow slip, as the embodiment according to 3 , In addition, the pressure loss is also in the embodiment according to 4a relatively large, as it is in the flow space 4 again is a single, continuous flow space of considerable length (see also 1 and 2 ).

4b shows a further development of the embodiment according to 4a with optional frontal cooling coil 7 ' with addition or discharge 13 . 14 for a tempering medium.

From the German patent application DE 10 2017 117 263 is a temperature control device for an electric module, in particular for a battery module or for an electric motor, having the following features: It comprises a substantially complete recording of the electric module, with the exception of electrical connection contacts and / or an output shaft thereof formed shell, which sheath a comprising tubular wall section. In the tubular wall section, it has at least one corrugated region in which the casing has a plurality of shafts running parallel to each other, which corrugations extend substantially transversely to a longitudinal axis of the tubular wall section and together on at least one of their respective first and second end sections go over an associated distribution and collection channel of the jacket. It comprises at least one supply line for a tempering fluid, which feed line opens into the distribution and collection channel. And it includes a derivative of the tempering fluid, which derivative is discharged or diverted from the distribution and collection channel.

The revelation of DE 10 2017 117 263 is hereby incorporated by reference in the present application in full.

On this basis, there is a need for a tempering generally for tempered (i.e., to be heated or cooled) body, with which a uniform temperature control can be done with the lowest possible pressure loss, while the material and cost should be minimized with flexible adaptability to different Temperieranforderungen.

This object is achieved by a Temperiermodul with the features of claim 1, by an arrangement of Temperiermodulen with the features of claim 15, by a tempering with the features of claim 17, by an electric module with the features of claim 18, by an arrangement of electric modules with the features of claim 19, 20 or 21 and by a method with the features of claim 22.

Advantageous developments of the idea according to the invention are the subject of dependent claims.

A tempering module according to the invention for an electric module, in particular for a battery module or for an electric motor, comprising: a casing designed to substantially completely accommodate the electric module, with the exception of electrical connection contacts and / or an output shaft thereof, which casing comprises a tubular wall section; in the tubular wall portion, at least one corrugated portion, in which the sheath comprises a plurality of shafts parallel to each other, which shafts extend substantially transverse to a longitudinal axis of the tubular wall portion and collectively at least one of their respective first and second end portions into an associated manifold - and collecting channel of the casing go over; at least one supply line for a tempering fluid, which supply line opens into the distribution and collection channel; and a discharge for the tempering fluid, which discharge is discharged or branched off from the distribution and collection channel; wherein the discharge line is designed and provided to be fluid-conductively connected to the supply line of a further, substantially identical tempering module, preferably by directly connecting the discharge line to the supply line, e.g. by engaging (inserting) or by preferably integrally bonding (for example gluing) over the edge regions of the supply line of a temperature control module to the outlet of another, adjacent temperature control module.

In the present case, the term "electric module" generally refers to a body to be tempered, which is supplied with or provides electrical energy and which accordingly has electrical connection contacts (terminals). In the case of an electric motor, an output shaft may also be present.

The distributor and collecting channels can preferably be designed as smooth tube regions, in which the sheath consequently does not have any corrugation. This is advantageous for reasons of flow guidance; however, the invention is not limited to such embodiment.

The distribution and collection channels may be formed integrally with the rest of the tempering module or the sheath, or they may be formed as separate components and preferably cohesively connected to the rest of the tempering (the sheath). Preferably then the supply line and the drain are formed as elements of these separate components.

A tempering module according to the invention or a tempering device according to the invention, which comprises a number of tempering modules according to the invention, serves for essentially completely accommodating such an electric module. In this context, "essentially completely" means that at least the said electrical connection contacts and / or the output shaft of the electric module can protrude out of the casing, in order in particular to attach electrical connecting lines or to make use of the generated driving force of the electric motor. Said casing comprises a tubular wall portion, which means that this wall portion is formed circumferentially closed. In the tubular wall section is at least one corrugated region in which the sheath has a plurality of parallel to each other extending waves. Such embodiments are known for example from bellows or corrugated pipes or corrugated hoses. The said shafts extend, with the exception of their end portions, transversely to a longitudinal axis of the tubular wall portion. At the end sections mentioned, the shafts - preferably with a constant change in their course - merge into an associated distributor and collecting channel (without shafts) of the sheathing. In this context, the term "under constant change" means that only a gradual change of the wave path from said extension transversely to the longitudinal axis of the tubular wall portion into the distribution and collection channel takes place. This should be avoided with appropriate (optional) embodiment of the temperature control according to the invention a vortex formation, which limits pressure losses and improves the tempering. Furthermore, the tempering module according to the invention also comprises a supply line for a tempering fluid, which supply line opens into the distribution and collection channel. Finally, there is a derivative of the tempering fluid, which branch is discharged or branched out of the distribution and collection channel. The tempering fluid thus passes through the supply line in the first distribution and collection channel and is distributed from there to the mutually parallel waves. In addition to the flow through these waves, the tempering fluid from the distribution and collection channel enters the said discharge line. In this way, there is a mass flow distribution for the tempering fluid, which is partially passed through the shafts connected in parallel and partly for discharge. Since the discharge is designed and intended to be fluid-conductively connected to the supply line of a further, essentially identical temperature control module, a plurality of temperature control modules according to the invention can be interconnected (plugged together) or combined to form a larger arrangement of temperature control modules (a temperature control device). The result is, with a lower pressure loss and uniform tempering effect, a flexible applicability of the temperature control module according to the invention.

Due to the similarity of the tempering module according to the invention with a (metal) bellows known as such, the solution according to the invention can also be referred to as a "cooling bellows" or generally "tempering bellows". Since the machines and processes required for its production are known, there is also a simple and consequently inexpensive manufacturability. An additional outer seal is not required.

A method according to the invention for controlling the temperature of at least one electric module, in particular a battery module or an electric motor, with a tempering module according to the invention, an arrangement of tempering modules according to the invention or a tempering device according to the invention comprises that a tempering fluid, preferably water, optionally with additives, an oil or a dielectric, for example 3M ™ Novec ™ High-Tech Liquids, is directed to the drain via a feed line through the corrugations in the corrugated region of the tubular wall section. In the course of the waves, a parallel flow guidance of the tempering fluid takes place, as already mentioned.

According to a development of the tempering module according to the invention, it is provided that a main flow direction of the tempering fluid in the distribution and collection channel in the region of the supply line and / or in the region of the discharge is substantially parallel to the longitudinal axis of the tubular wall section. In this way, the tempering fluid can be introduced axially parallel with appropriate space reduction in the distribution and collection channel or discharged from the distribution and collection channel.

Accordingly, in another development of the tempering module according to the invention, provision may be made for the supply line and / or the discharge to be oriented essentially transversely to the longitudinal axis of the tubular wall section. This results in an improved combinability of the temperature control modules.

In particular, according to another embodiment of the tempering module according to the invention, in which the supply line and the discharge are aligned with each other, the Temperiermodule can be arranged side by side with parallel longitudinal axis and fluid-conducting connect to each other, preferably by inserting the instructions of a tempering in the supply of another temperature control module.

According to yet another development of the tempering module according to the invention can be provided that the tubular wall portion has two preferably diametrically opposed corrugated regions and two preferably diametrically opposite distribution and collection channels. As a result, it is possible to achieve a cooling effect which is as uniform as possible relative to the circumference of the electric module. However, the invention is in no way limited to such embodiments: for example, it may be advantageous not to arrange the distribution and collection channels diametrically opposite each other but together on one side of the electric module. The waves on one side of the electric module are then significantly longer than the waves on the other side of the electric module. Thus, the tempering effect can be specifically influenced. For example, the power electronics of an electric motor can be arranged in the region of the shorter waves in order to optimize the local temperature control in a targeted manner.

Another development of the temperature control module according to the invention provides that each of the two distribution and collection channels has a supply line and a drain. As a result, the flow behavior is improved. It is also possible to provide an outflow and a return flow of the tempering fluid in the case of an arrangement of a plurality of tempering modules according to the invention.

Yet another refinement of the tempering module according to the invention provides that the supply lines and the leads are arranged parallel to one another and preferably essentially in a common plane in order to further improve the (direct) combinability of the tempering modules.

Yet another development of the tempering according to the invention provides that the tubular wall portion has a round, specially circular, cross-section, an oval cross-section or a substantially (for example, rounded corners) rectangular cross-section and preferably formed either in one piece or composed of at least two half-shells is. In this case, the two half-shells can be composed by cohesive connection in the distribution and collection channels. The mentioned round, specially circular, oval or rectangular cross-section of the tempering device is well suited for receiving rotationally symmetrical bodies or prismatic cells (prismatic cells), which describes a common geometry of currently used battery cells or battery modules in the field of electromobility. If the tubular wall section is composed of half-shells, these can be produced particularly cost-effectively as simple deep-drawn parts.

A specific refinement of the tempering module according to the invention provides that the supply line has a clear internal diameter which substantially corresponds to an outside diameter of the discharge, or vice versa. This can in particular bring about a particularly easy connectability of the tempering device (by plugging in the discharge of one module into the supply line of another module, or vice versa). The derivative can also be expanded terminally (conically). Accordingly, the supply line can be tapered conically. A reverse embodiment is possible in each case.

In another development of the tempering module according to the invention, it is provided that at least one sealing element for sealing a connection with a further tempering module is arranged on the supply line and / or on the discharge line in order to fluidly seal an arrangement of a plurality of tempering modules according to the invention.

In yet another further development of the tempering module according to the invention, on the other hand, it can be provided that the supply line and / or the discharge line is / are arranged in a middle region of the tubular wall section with respect to a longitudinal extension thereof. This also makes it possible to specifically influence the tempering effect.

In order to improve the tempering even further, it may be provided in a further development of the tempering module according to the invention that the casing has an end wall section closing off the tubular wall section at least on one end side, preferably with the exception of a passage of electrical connection contacts or an output shaft. This end wall section may comprise at least one further corrugated region, in which the sheath has a plurality of end-side shafts running parallel to one another. These end-side shafts may extend transversely to a longitudinal axis of the tubular wall section and pass into the distribution and collection channel anal. In this way, the tempering module according to the invention is supplemented by end-side tempering devices, which are formed essentially analogously to the tempering device in the tubular wall section in order to further improve the tempering effect.

In order to enable the most space-saving arrangement of Temperiermoduls invention, another embodiment provides that the corrugated region is formed such that wave crests of the corrugated region in troughs of a same corrugated area can be accommodated, with the respective wave crests and troughs preferably over the entire surface Touch to allow a close arrangement. In this way, two appropriately designed Temperiermodule invention closely adjacent (quasi toothed) can be arranged by quasi nestled in the region of their wave crests and troughs.

It has proven to be particularly advantageous to further develop the tempering module according to the invention in such a way that two different variants thereof exist, which essentially differ from one another only with regard to an axial position of the corrugated region or corrugated regions. In this case, the corrugated region according to one variant is preferably displaced by half a wavelength with respect to the corrugated region according to the other variant. If a tempering module according to the first variant and a tempering module according to the second variant with their wave crests and their troughs (and their respective inlets and outlets) are plugged together, as described above, thereby said offset with respect to the axial position of the corrugated areas straight be compensated so that - with the same overall length - neither of the two tempering protrudes in the axial direction relative to the other. This in turn contributes to an extremely compact space utilization, which plays a major role especially in the automotive sector. If the cooling bellows designed in another special development such that the waves are asymmetrical, one and the same part can be installed reciprocally. The two-way construction requires only two equal parts compared to two different ones, which simplifies production.

Yet another refinement of the tempering module according to the invention provides an arrangement of tempering modules in which at least one copy of the two differently designed variants is provided, which are arranged adjacent to one another such that wave crests of the wavy region of one variant with wave troughs of the corrugated region of the other variant in FIG Are engaged. The achievable advantages have already been mentioned above.

In a further development of the tempering module according to the invention, the tubular wall portion has two preferably diametrically opposed corrugated areas and two preferably diametrically opposite distribution and collection channels, can still be provided that at least two tubular wall sections arranged parallel to each other and with a lateral distance and in the manifold - And collecting channels are each fluid-tightly interconnected. This can for example arise from the fact that a corresponding connection part (for example, a metal sheet) is materially connected from the outside in said distribution and collection channels. In this way, between the two tubular wall sections, a further tubular line section for receiving an electric module, again with the exception of electrical connection contacts or a drive shaft thereof. By cleverly connecting two spaced-apart tempering modules, a further tempering module is thus provided in an area between these tempering modules, so that an extremely compact arrangement results for accommodating a multiplicity of electric modules.

According to another aspect, the invention also relates to a tempering device comprising a plurality of tempering modules according to the invention or correspondingly developed, in which at least one derivative of a tempering module is connected fluidically (directly) to a feed line of another tempering module, wherein preferably one terminal tempering module does not conduct a discharge for connecting a further tempering module has to complete the temperature control device fluidly.

In yet another aspect, the invention also relates to an electric module, in particular a battery module or an electric motor, with a tempering module according to the invention. The electric module is accommodated in the tubular wall section or one of the tubular wall sections or the further tubular line section and can rest against the respective tubular wall section at least in the corrugated area and / or in the further corrugated area (as defined above). In order in particular to prevent mass flow slippage of the temperature control medium and also to effect stiffening of the accommodated electric module, it may additionally be provided that the electric module and the temperature control module are fixedly connected to one another, in particular by cohesive connection in the region of wave troughs in the corrugated area and / or in the further corrugated area. This can be counteracted in battery cells deformation by chemical and thermal influences.

To be extremely advantageous, an arrangement of at least two electric modules with an arrangement of Temperiermodulen has proven, which Tempering modules at least each include a copy of the two differently designed variants, which are arranged as defined above adjacent and in engagement, in each of which an example of the two differently designed variants an electric module is arranged.

Likewise highly preferred is an arrangement of at least three electric modules with a special tempering module, as described above, in which between the two tubular wall sections, a further tubular conduit section is formed, received in each of which an electric module in the two tubular wall sections and in the other tubular conduit section is.

Also particularly preferred is an arrangement of a plurality of electric modules with a temperature control device according to the invention, in each of which an electric module is preferably accommodated in each temperature control module.

1 shows a tempering according to the prior art according to EP 3 056 847 A1 , which has already been discussed in more detail in the introductory part of the description. The invention has for its object to further develop such a configuration advantageous.

A first possibility of such an advantageous development is in 2 already discussed above. The object of 2 is not part of the present invention, but may constitute a further invention claimed separately if desired.

In 3 is a perspective view of the embodiment according to 2 shown. This has already been pointed out above.

Also the embodiment according to 4 is not the subject of the present invention, but if desired claimable as a separate, further invention. Also the solution according to 4 achieved - as the solution according to 2 - An advantageous development of the subject 1 , This was pointed out in detail in the introductory part of the description.

The following 5 to 25 according to DE 10 2017 117 263 show features of the present invention, which are also feasible in their implementation. In the 26 ff additional features are included, which are the subject of the present invention from the disclosure of DE 10 2017 117 263 delimit.

5 shows in longitudinal section a detail of a tempering according to DE 10 2017 117 263 , which can be referred to as "cooling bellows" or generally as "tempering bellows" according to the explanations in the introductory part of the description. A bellows regularly has - in addition to smooth cylindrical connecting ends - a tubular, corrugated wall section which in 5 at reference numerals 10a is shown. The entire tempering is denoted by reference numerals 10 designated. It points in the wavy area 10a a plurality of waves, of which in 5 for reasons of clarity, only a few respective peaks with the reference numeral 10b are provided. The tempering bellows 10 surrounds a body to be tempered 1 (in the present case a so-called electric module), in the area of its surface (lateral surface) 1a , This is the tempering bellows 10 in the area of its troughs 10c on the surface mentioned 1a and there may be fixed in particular materially. As a result, the mentioned mass flow slip can be prevented; In addition, the cohesive connection of the Temperierbalgs 10 to the body to be tempered 1 lead to a stiffening of the latter, which in particular in the case of an embodiment of the body 1 in the form of a battery module or a battery cell (especially in the form of prismatic, deep-drawn or extruded battery cups) may be advantageous and desirable.

In the context of the disclosure according to DE 10 2017 117 263 is a tempering or tempering fluid through the between body surface 1a and an inside of the tempering bellows 10 defined flow space 4 directed. Unlike the prior art, the flow space is 4 but not a single, continuous, helical flow space, but a plurality of parallel flow chambers, which will be discussed in more detail below. As a result, the tempering effect can be improved, and pressure losses are reduced.

6 shows, in the form of a longitudinal section, a tempering device (tempering bellows) 10 according to DE 10 2017 117 263 with integrated electric module in the form of a battery module (prism cell) 20 , With reference numerals 20a and 20b are electrical connection contacts of the electric module 20 symbolically represented. reference numeral 11 denotes a jacket of the tempering device 10 , Which sheath is designed to the electric module 20 - with the exception of the connection contacts 20a . 20b - to record completely. The tempering bellows 10 or the sheath 11 already includes the basis of 5 illustrated tubular wall section 10a or the corrugated area in which the sheath 11 or the tempering bellows 10 a plurality of parallel shafts, of which in 6 only the (crest lines) of the mountains 10b symbolic are shown. These waves extend (with the exception of the right and left in 6 illustrated end sections, in 6 with reference number 10d respectively. 10e are designated) transverse to the longitudinal axis L the arrangement or the tubular wall section 10a , At the mentioned end sections 10d . 10e of which the former also as first end sections 10d and the latter also as second end portions 10e are designated, the respective course of the waves or wave crests changes 10b at the transition into an associated distribution and collection channel (without waves). Accordingly, in 6 a first distribution and collection channel with the reference numeral 12.1 and a second distribution and collection channel with the reference numeral 12.2 , The mentioned continuous change of the respective course is such that the waves or wave peaks in the respective distribution and collection channel 12.1 . 12.2 are curved so that their course to a course or a longitudinal extent of the respective distribution and collection channel 12.1 . 12.2 approaches. In addition, the wave height can gradually decrease to zero. reference numeral 13 denotes a supply line for a tempering fluid, wherein an associated arrow denotes a mass flow of the tempering. reference numeral 14 stands accordingly for a derivative of the tempering fluid. The supply line 13 flows into the first distribution and collection channel 12.1 while the derivative 14 from the second distribution and collection channel 12.2 is diverted or branched off. Thus, the first distribution and collection channel could be 12.1 also refer to as a pure distribution channel, and the second distribution and collection channel 12.2 as a pure collection channel, which distinction is not made here and in the following.

The vertical dotted lines in 6 interpret a corresponding lateral boundary of the electric module 20 at. This is so the side of the said distribution and collection channels 12.1 . 12.2 limited. The peripheral area between said distribution and collection channels 12.1 . 12.2 is occupied by the tubular wall portions having corrugated portions, as in FIG 5 shown. In other words, the embodiment according to 5 provides a view of the subject in 6 in a sectional plane which is at 90 ° to the cutting plane in 6 is arranged twisted. Accordingly, the reference numeral 1 in 5 denote the same element as the reference numeral 20 in 6 ,

An at reference numerals 13 inflowing tempering medium is correspondingly from the first distribution and collection channel 12.1 acting as a kind of distributor, through the flow spaces 4 within the waves (compare 5 ) around the electric module 20 passed around and then in the distribution and collection channel 12.2 collected again. Subsequently, the derivation at reference numerals 14 , The flow around the electric module 20 according to 6 takes place in a plurality of parallel flow channels 4 (see 5 ). The curvature of the waves in the first and second end sections 10d . 10e ensures that vortex and turbulence formation are avoided, which helps to minimize pressure losses and to improve the tempering effect.

6 shows a particularly preferred embodiment of the temperature control according to DE 10 2017 117 263 in which the supply line and the discharge of the tempering takes place at different (front) sides of the arrangement. On the other hand shows 7 a modification of this embodiment, wherein the supply line 13 and the derivative 14 each approximately centrally on opposite sides of the casing 11 are arranged as shown. Accordingly, the waves or wave peaks 10b of the tempering bellows in the end sections 10d . 10e designed differently than in the embodiment in 6 , Specifically, they are symmetrical with respect to a connection line of lead 13 and derivative 14 curved to this (imaginary) connecting line, as shown.

8th shows another embodiment, in the supply line 13 and derivative 14 are arranged on a same end face of the arrangement. Accordingly, here are the waves or wave peaks 10b at their end sections 10d . 10e in the same direction (upwards in each case 8th ) curved.

9 shows the embodiment according to 8th in cross section. Here you can see how the electric module 20 on both sides in the wavy areas 10a of the tubular wall portion is acted upon by the temperature control, which in the distribution and collection channel 12.1 fed and in the distribution and collection channel 12.2 is discharged again.

10 shows an overall perspective view of the arrangement according to 8th or 9 , The wavy areas 10a or wave mountains 10b are particularly easy to recognize here. It is also in 10 to recognize that the sheath can be composed of a plurality of partial shells or half-shells, as symbolized by corresponding joint lines VL. In this way, the individual components of the casing can be manufactured in a simple and cost-effective manner as deep-drawn parts, which subsequently (cohesively) to the casing 11 can be connected.

11 shows in plan view a detail of the article 10 , Here is particularly easy to see how the waves or wave mountains 10b in the distribution and collection channel 12.2 lead or expire, so that at least in the apex S actually results in a completely smooth wall course.

12 shows a side view of the embodiment according to in particular 10 ,

In 13 is one opposite 8th ff. Modified arrangement shown in which the electric module 20 is designed as an electric motor, the front side, in particular with its output shaft 21 or the like, from the jacket 11 protrudes. This is otherwise formed similar to in 8th ff., However, has a total of a rather circular cross-section, while the embodiment according to 8th ff. is rather oval. The supply line 13 and the derivative 14 are designed as radially outwardly bent connection piece.

14 shows isolated only the resulting flow space, ie the supply line 13 , the first distribution and collection channel 12.1 , the wavy area 10a , the second distribution and collection channel 12.2 as well as the derivative 14 along with the end sections 10d . 10e , The between the wave crests 10b shown interstices are those areas in which the tubular wall portion on the surface or outside of the electric module (in 14 not shown) is applied and preferably connected to this material fit, so that in these areas no flow of the temperature control (Temperierfluid) takes place.

15a shows an extremely preferred embodiment of the temperature control according to DE 10 2017 117 263 in the context of an arrangement with four electric modules 20 , The second electric module 20 from above and the fourth electric module 20 from above are each again in a sheath 11 according to, for example 8th or 10 recorded, which sheath 11 a tubular wall section 10a includes. The tubular wall section 10a again comprises at least one corrugated area, which in 15a for reasons of clarity is not separately designated. The dotted lines in 15a symbolize the course of the wave mountains 10b in the respective corrugated area. reference numeral 12.2 denotes - as before - the second smooth tube region, which merges into the (not shown) derivative.

The mentioned second and fourth electric modules 20 are so within the respective sheath 11 arranged that a directly adjacent electric module 20 the jacket 11 in the area of the wave mountains 10b touches as shown. For example, the third electric module 20 from above between the waves of the tempering bellows for the second electric module 20 from above and the fourth electric module 20 enclosed from above, so de facto the troughs of the second and fourth electric module 20 as wave mountains for this third electric module 20 act. To the thus created flow space for the third electric module 20 from above (and accordingly for the first electric module 20 from the top) to the outside, are connecting parts 15 provided (for example, from sheet metal), which preferably cohesively with the sheaths 11 in the area of the apex S (cf. 11 ) in the distribution and collection channel 12.2 (and accordingly in the distribution and collection channel 12.1 , not shown). Of course, the individual connecting parts 15 be formed in the form of a single, continuous connection part. This results in each case a closed flow space 16 , for tempering the first, third, ... electric module 20 can be used. In this way is only for every second electric module 20 the use of a complete cooling bellows or Temperierbalgs required, which means a corresponding material and cost savings.

According to the variant in 15b are at reference numerals 16 ' one (or more) holes (holes) in the distribution and collection channel 12.2 intended. This can be in the range 10b an internal series connection of the cell cooling can be realized. An external transfer of the tempering medium flow is not required, whereby the implementation is simple, small, light and inexpensive.

16 shows an embodiment in which two temperature control according to DE 10 2017 117 263 staggered and with respect to the corrugated areas 10a are configured such that the wave crests of an arrangement just intervene in the troughs of the other arrangement. In this way, two temperature control according to the invention can be arranged in a confined space. It is particularly advantageous in this context if the temperature control device according to the invention is present in two variants, which differ with respect to the axial position of the corrugated region with respect to the longitudinal extent of the sheath - preferably so that the corrugation in the one variant just by half a wavelength shifted from the other variant. Then let the two corrugations according to 16 engage, without the one arrangement of tempering and electric module would protrude in the axial direction relative to the other arrangement, which allows an extremely compact design.

In 17 is again an embodiment substantially according to 13 without the corresponding electric module 20 (see 13 ) is shown in a plan view. The letter Q denotes a discharged heat quantity.

18 shows a variant of the embodiment according to 17 in which - unlike in 13 . 14 or 17 - Only a single radial bulge is provided, which both the supply line 13 as well as the derivative 14 and the corresponding distribution and collection channels 12.1 . 12.2 receives. In between is at reference numerals 17 provided a kind of partition, which is the area of the supply line 13 from the area of the derivative 14 fluidically and preferably also thermally separated.

19 shows another development of the embodiment according to 17 , While in 17 supply 13 and derivative 14 or the corresponding distribution and collection channels 12.1 . 12.2 are arranged diametrically opposite, this is the subject of 19 not the case: supply line 13 and derivative 14 are shifted towards each other, ie arranged asymmetrically. In this way, two flows of Temperierfluids (tempering), resulting in 19 with ① or ② are designated. These include flow rates v ₁ respectively. v ₂ that can be different from each other. While an electric module 20 inside the casing a quantity of heat Q ₁ is outside the shell 11 at reference numerals 18 a further heat source, for example in the form of a power electronics or control electronics provided, the amount of heat Q ₂ generated, which additionally acts on the arrangement from the outside (compare the arrows in 19 ). Due to the shorter flow path in the area ① there is an increased flow velocity v ₁ of the temperature fluid, which means improved heat dissipation. It is therefore advantageous if - as in 19 shown - the additional heat source 18 is arranged in the region of this shorter flow path, ie in the region in the supply line 13 and derivative 14 circumferentially closer together, as shown. In area ②, a lower speed results due to the larger flow path length v ₂ so that the heat dissipation is lower. However, this is sufficient, because in area ② no additional heat source 18 is available.

20 shows a longitudinal section through an electric module 20 that with a sheath 11 a tempering device is surrounded, as described above by way of example with reference to a plurality of embodiments. Essential in the embodiment according to 20 is now that even the front side a sheath is provided - in particular by the sheathing 11 through a kind of lid 11 ' closed at the front. This cover or end wall section 11 ' also comprises at least one corrugated area, which in 20 with reference number 11a ' is designated. The dashed lines 11b ' indicate different courses of wave crests in this area. The corresponding shafts are parallel to each other transversely to the longitudinal axis L the sheath 11 or the electric module 20 and the associated tubular wall portion (not designated). At their respective first and second end portions 11d ' . 11e ' go the waves in the respectively associated first distribution and collection channel 12.1 or second distribution and collection channel 12.2 the sheath 11 over, as shown. In the area of the troughs (not marked) of the front section 11 ' this is located on the front side of the electric module 20 on, as in 20 shown.

In 21 is a plan view of the end wall portion 11 ' according to 20 shown. As you can see, those through the wave crests 11b ' symbolized flow channels either from the first distribution and collection channel 12.1 to the second distribution and collection channel 12.2 be trained consistently, or they can branch on the way.

The end wall section 11 ' according to 20 . 21 can with the rest of the sheathing 11 (Tempering or cooling bellows) soldered or welded. Preferably, it is designed as a simple sheet-metal deep-drawn part or -Prag part.

22 shows a variant of the embodiment according to 20 , Shown is an electric module 20 in the manner of an electric motor with projecting output shaft 20c , According to 22 has the end wall portion 11 ' a wavy area 11a ' with parallel waves or wave crests 11b ' on (looking in the direction of the wavelength extension). The wave height and thus the cross section of the flow channel can increase in the radial direction from the inside to the outside in order to achieve a more uniform tempering effect. The same is true in the shaft arrangement according to 21 possible. Opposite the representation in 20 is the representation in 22 turned 90 °: while in 20 the viewing direction across the course of the waves or wave crests 11b ' is, you look in 22 in the direction of this wave mountains 11b ' ,

23 shows a frontal plan view of the arrangement according to 22 ,

24 shows an embodiment of the cooling bellows as Vollbalg (waves with constant cross-section over the entire circumference) in an arrangement of five to be tempered electric modules 20.1 - 20.5 (eg battery cells). This allows a more even temperature to be set. This can be achieved by a coolant flowing into the cooling bellows (generally a tempering fluid) via external connecting pipes 30 and one outside the cooling bellows (in the flow space 16 ) flowing cooling fluid is transferred through the waves. Now become the different cooling currents fed in the opposite direction, the temperature gradient can be smaller due to the heating of the cooling liquid, resulting in a more uniform cooling result. Thus, a countercurrent cooling can be achieved.

25a to 25c show views of a variant of the embodiment according to 10 , Here are the supply line 13 and the derivative 14 as lateral Aushalsungen the sheath 11 trained, in particular the 25c good to see.

In 26 is an overall perspective view of an inventive tempering shown, the analogous to the above total with the reference numeral 10 is designated. The tempering module 10 In this respect corresponds functionally to the tempering device or the tempering bellows according to DE 10 2017 117 263 , see. above figures 5ff.

The tempering module 10 comprises a tubular, corrugated wall section, in turn with the reference numeral 10a is designated. It points in the corrugated area 10a a plurality of waves, again for reasons of clarity, only a few peaks with the reference numeral 10b are provided. The tempering bellows 10 forms - analogous to the above - a sheath 11 into which a tempering fluid (not shown) is introduced according to the invention.

Analogous to the above description of 6 is in 26 a first distribution and collection channel with the reference numeral 12.1 and a second distribution and collection channel with the reference numeral 12.2 , Due to the selected perspective view, only the second distribution and collection channel 12.2 (partially) recognizable. The first distribution and collection channel 12.1 is in 26 recognizable by the fact that the tempering 10 has a bulge on the outside, which accommodates said distribution and collection channel (inside).

As in 6 also referred to in 26 reference numeral 13 a supply line for a tempering fluid, while reference numerals 14 accordingly stands for a derivative of the tempering fluid. The supply line 13 flows into the first distribution and collection channel 12.1 while the derivative 14 is derived from this or branched off. According to 26 there is an identical supply line 13 and an identical derivation 14 also in the region of the second distribution and collection channel 12.2 , of which, for the sake of the selected representation, only the supply line 13 is recognizable.

A through the supply lines 13 in the first and second distributor collecting channel 12.1 . 12.2 initiated tempering fluid is distributed in this distribution and collection channels 12.1 . 12.2 and from there into the area of the bellows or wave crests 10b , with the exception of the aforementioned distribution and collection channels 12.1 . 12.2 - Completely around the temperature control module or the Temperierbalg 10 are arranged around and formed. In this way, one inside the tempering bellows 10 absorbed electric module (not shown) in full contact with the tempering fluid in contact. This has already been explained in detail above with reference to FIGS. 5ff.

Notwithstanding this is the subject according to 26 not or only insignificantly provided that the wave crests 10b in the area of distribution and collection channels 12.1 . 12 , 2 undergo a course change, as for example in 6 . 8th or 10 is shown explicitly. Although such a change in course, of course, in the subject of 26 (and the following figures) is possible, also simply a discharge from the relevant distribution and collection channel 12.1 . 12.2 take place in the circumferential direction.

As 26 can still be seen, have the leads 13 a clear inside diameter DI which essentially has an outer diameter DA in the region of the discharges 14 equivalent. In addition, the derivatives have 14 at reference numerals 14a a circumferential recess or groove, which is designed and provided for receiving a (not shown) sealing element, for example an O-ring. The supply lines 13 are to their free end 13a extended conically, while the derivatives 14 to their free end 14b are conically tapered. In this way, the tempering 10 according to 26 with its derivatives 14 into the supply lines 13 an adjacent, identical Temperiermoduls 10 be plugged to connect the said temperature control fluid-conducting.

For this purpose, the supply lines 13 and the derivatives 14 along a common axis FA arranged in alignment.

According to the embodiment in 26 are the supply lines 13 and the derivatives 14 approximately at the middle height of the entire tempering module 10 relative to its longitudinal axis LA. The escape axis FA of the derivatives 13 and supply lines 14 is arranged at a right angle with respect to the longitudinal axis LA as shown, and they are also perpendicular to an outer surface of the Temperiermoduls 10 in the area between the distribution and collection channels 12.1 . 12.2 extends.

Reference character FL designates - such as in 10 - in turn joint lines, along which the sheathing 11 is composed of a plurality of partial shells or half shells.

In 27 is the tempering module 10 according to 26 illustrated in a plan view, in particular the embodiment in the supply lines 13 and derivatives 14 easy to recognize. For more details is not to enter.

28 is the tempering module 10 according to 26 in a longitudinal section, that is, in a sectional plane transverse to the longitudinal axis LA according to 26 shown. You can see how the supply lines 13 into the distribution and collection channels 12.1 . 12.2 lead and how the derivatives 14 from the mentioned distribution and collection channels 12.1 . 12.2 are discharged. In the area of distribution and collection channels 12.1 . 12.2 There are no flow guide elements that could influence the flow of the tempering fluid (not shown). Rather, a partial flow of Temperierfluids passes directly from the supply line 13 for derivation 14 from there into an adjacent tempering module 10 to be able to flow. However, due to an adjusting dynamic pressure, a partial flow of the tempering fluid into the distribution and collection channel 12.1 respectively. 12.2 and from there into the interior of the wave crests (not shown; 26 ) of the tempering, in order for a circumferential temperature of one in the tempering 10 used to provide electrical module (not shown).

29 shows the tempering according to 10 in a side view. Here are the wave mountains 10b to recognize the tempering bellows particularly well. It stands out that the wave mountains 10b on one side of the tempering module 10 straight with troughs 10c on the other side of the tempering module 10 correspond. The particular advantages of such an embodiment have already been mentioned above; it is then possible, two tempering 10 to arrange closely adjacent, with the wave crests 10b on one side of a tempering just in the troughs 10c engage on the facing side of the adjacent Temperiermoduls. This will be explained below using 32 be particularly clear.

As in 29 may be indicated by reference numerals 100 between two adjacent temperature control modules 10 an electrically insulating film (insulating film) or the like may be attached to ensure that adjacent electric modules or Temperiermodule 10 electrically (galvanically) are separated from each other.

30 shows the temperature control module 10 according to 26 in a frontal view overlooking the free ends 14b the supply lines 14 , Especially the outwardly bulging wall course in the area of distribution and collection channels 12.1 . 12.2 falls into the eye.

In 31 is now an electric module arrangement of a total of seven electric modules 20 shown, each electric module 20 from a temperature control module 10 is surrounded according to Figure 26ff. According to 31 are the electrical modules 20 designed as battery modules (so-called prism cells). reference numeral 20a denotes a first electrical arrester and reference numerals 20b denote a second electrical arrester of a respective electric module 20 , The arresters 20a . 20b have mutually opposite electrical polarity (+/-). For adjacent electric modules (battery cells) 20 can the arresters 20a . 20b can be arranged interchanged, as shown, in order to be able to accomplish in particular a series connection of the battery cells in a simple manner. With reference numerals 20c For each battery cell (each electric module) 20 a (closed) filling opening is shown, which is usually intended for filling the respective cell with an electrolyte or the like. This is familiar to the person skilled in the art.

Essential to the invention in the illustration according to 31 is now that the individual tempering modules 10 fluidly connected to each other, in each case the derivatives 14 a tempering module 10 directly into the supply lines 13 an adjacent tempering module 10 are plugged in, as already described above. According to the arrows FL in the first temperature control module 10 initiated tempering fluid thus passes gradually into all Temperiermodule 10 until it's out of the derivatives 14 of the last in the flow direction Temperiermoduls exits again. However, it is within the scope of the invention that in the flow direction last Temperiermodul 10 deviating form, so that this tempering either has no derivatives or properly sealed discharges. In this way, the tempering fluid introduced remains in the temperature control modules connected in series 10 formed tempering. However, it is in a modification of the embodiment according to 31 also possible, the tempering fluid only one of the supply lines 13 of the first temperature control module 10 according to 31 initiate. If now the last in the flow direction tempering 10 has no derivatives, as described, the tempering is after flowing through said temperature control at the other supply line 13 of the first temperature control module 10 re-emerge after all tempering modules 10 flows through and thus for effective cooling of the electrical shell 20 has taken care of. This is in 31 by the reference numeral FL ' symbolized arrow symbolizes.

32 shows the arrangement of tempering 10 according to 31 in longitudinal section. It is easy to see how neighboring tempering modules 10 with their wave mountains 10b and troughs 10c interlock, as described above. In addition, it is easy to see how the electric modules 20 with their outer module walls 20a from the inside to the wave mountains 10c the temperature control modules 10 issue. This ensures inside the wave mountains 10b the temperature control modules 10 for defined flow spaces for the tempering fluid, as well as results in a stiffening of Temperiermodule 10 ,

Finally shows 33 the arrangement according to 31 in another longitudinal section in the area of the supply lines 13 and derivatives 14 or in the area of distribution and collection channels 12.1 . 12.2 , As a result, the inventively created, continuous and contiguous flow space for the tempering fluid is again particularly clearly visible.

As those skilled in the art will readily appreciate, the invention is by no means limited to the fact that the leads 13 and derivatives 14 the individual Temperiermodule must be arranged centrally, in alignment or on both sides. In particular, supply line can 13 and derivative 14 be arranged at different heights, but this would mean that different variants of Temperiermoduls would have to be made. In addition, it is not mandatory that on both sides of the temperature control cable supply 13 and derivative 14 are formed, although an improved flow through the Temperiermodule with a tempering fluid and in particular the formation of a closed fluid circuit is made possible by this configuration.

In 34 an embodiment is shown in which the distribution and collection channels (only distribution and collection channel 12.1 is marked) are realized as separate components, in the figure with reference numerals 110 You have - without limitation - the shape of pipe sections with a specially oval cross-section and form the supply lines at their ends 13 and the derivatives 14 out. On their inside they also have a - without limitation - oval hole (not recognizable), the same with a breakthrough 111 in the shell corresponds, cf. 35 , This variant, in which the individual cells (electric modules, battery cells) 20 be connected by means of a laterally perforated distribution channel, therefore, includes that the horizontal and vertical distribution / collection channels in the form of a laterally connected oval, horizontal distribution channel, which is designed as a separate component, are executed. A similar distribution channel may preferably be provided on the rear side of the arrangement.

The choice of material is very free in this embodiment and can - both for the components 110 as well as for the rest of the sheathing 11 - go towards plastic. As a sealing, insulating and fixing element between sheathing 11 and distribution channel component 110 on the one hand and between the distribution channel components 110 on the other hand, a cohesive connection (adhesive bond) comes into consideration.

In 36 an embodiment is shown in which the distribution and collection channels 12.1 . 12.2 as bulges 112 the sheath 11 are realized and which works without the said horizontal distribution channel as a separate component, the bulges 112 have - without limitation - a specially about D-shaped cross-section and form at their ends the leads 13 and the derivatives 14 with flat edge areas 113a (only for the derivation 13 visible; see. 37 ) out. At their (concave) inside form the bulges 112 the distribution and collection channels 12.1 . 12.2 go out and go directly into the corrugated areas of the sheath 11 above. This variant therefore includes that the individual temperature control modules 10 be directly (cohesively) connected to one another via the aforementioned edge regions, preferably glued.

Again, the choice of materials is very free and can go in the direction of plastic. As a sealing, insulating and fixing element between the individual Temperiermodulen with each other is a cohesive connection (adhesive bond) into consideration. Unlike, for example, the variant according to 26 ff no separate seal is required.
