Description

The invention relates to a temperature control device for an electric module, in particular for a battery module or for an electric motor, according to claim 1.

Moreover, the invention relates to an electric module, in particular battery module or electric motor, with a tempering device according to the invention according to claim 17.

Furthermore, the invention relates to an arrangement of at least two or three electric modules with a tempering device according to the invention according to claim 25 or claim 26.

Finally, the invention relates to a method according to claim 27 for tempering an electric module, in particular a battery module or an electric motor, using 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 embodiment 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, since it is at the flow chamber 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 In order to avoid most of the problems listed above, there is still a need for a tempering generally for tempered (ie to be heated or cooled) body, with which a uniform temperature can be carried out at the lowest possible pressure loss and without mass flow slip, while the material and cost should be reduced.

This object is achieved by a tempering with the features of claim 1, by an electric module having the features of claim 14, by an arrangement of electric modules with temperature control device according to claim 15 or claim 16 and by a method having the features of claim 17.

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

A tempering device according to the invention for an electric module, in particular for a battery module or for an electric motor, comprises: 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 has a plurality of shafts parallel to each other, which shafts, except for their end portions, extend transversely to a longitudinal axis of the tubular wall portion and at their respective first and second end portions with continuous change their respective course in an associated first distribution and collection channel or second distribution and collection channel of the casing go over; a supply line for a tempering fluid, which feed line opens into the first distribution and collection channel; and a derivative of the tempering fluid, which derivative is discharged or branched off from the second distribution and collection channel.

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.

A tempering device according to the invention serves for substantially complete reception of 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, 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. As a result, a vortex formation should be avoided, which limits pressure losses and improves the tempering. Furthermore, the tempering device according to the invention also comprises a supply line for a tempering fluid, which supply line opens into the first distribution and collection channel. Finally, there is a discharge for the tempering, which branch is discharged or branched from the second 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. After parallel flow through these waves, the tempering enters the second distribution and collection channel and from there into the said derivative. In this way, there is a mass flow distribution for the tempering fluid, which is passed through the shafts connected in parallel. The result is a lower pressure loss and a more uniform tempering effect.

Due to the similarity of the temperature control device according to the invention with a (metal) bellows known as such, the solution according to the invention can also be referred to as "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.

An inventive method for controlling the temperature of an electric module, in particular a battery module or an electric motor, with a tempering device according to the invention, that a tempering fluid, preferably water, optionally with additives, an oil or a dielectric, such as 3M ™ Novec ™ high-tech fluids over a supply line is guided by the waves in the corrugated region of the tubular wall portion to the discharge. 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 device according to the invention, it is provided that a main flow direction of the tempering fluid in the first distribution and collection channel in the region of the supply line and / or in the second distribution and collection channel in the region of the discharge is substantially parallel to the longitudinal axis of the tubular wall portion. In this way, the tempering fluid can be introduced axially parallel with a corresponding reduction in space in the first distribution and collection channel or discharged from the second distribution and collection channel.

Accordingly, in another development of the temperature control device according to the invention can be provided that the supply line and / or the discharge is oriented substantially parallel to the longitudinal axis of the tubular wall portion or are.

According to yet another embodiment of the temperature control device according to the invention can be provided that the tubular wall portion has two preferably diametrically opposed corrugated areas 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.

Yet another refinement of the tempering device according to the invention provides that the tubular wall section has a round, especially circular, or an oval cross section and is preferably formed either in one piece or composed of at least two half shells. In this case, the two half-shells can be composed by cohesive connection in the distribution and collection channels. The mentioned round, especially circular or oval cross-section of the tempering device is well suited for receiving rotationally symmetrical bodies or so-called 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 development of the tempering device according to the invention provides that the supply line and the discharge line are arranged at a common end of the tubular wall section. This can in particular cause a particularly easy connectability of the temperature control.

In another development of the tempering device according to the invention, however, it is provided that the supply line and the discharge line are arranged at different ends of the tubular wall section. As a result, a more homogeneous tempering effect can be achieved.

In another embodiment of the tempering device according to the invention, on the other hand, provision may be made for the supply line and / or the discharge line to be arranged in a middle region of the tubular wall section with respect to a longitudinal extent thereof. This also makes it possible to specifically influence the tempering effect.

In a further development of this last-mentioned variant of the temperature control device according to the invention can be provided that the supply and / or the derivative are fan-shaped expanded to the first distribution and collection channel or to the second distribution and collection channel of the jacket and go into the waves , As a result, the temperature control effect can be influenced in a targeted manner via the flow conditions.

In a further development of the tempering device according to the invention, it can further be provided that the supply line and the discharge line are arranged offset at approximately the same circumferential position of the tubular wall section and, relative to a longitudinal extent thereof. This creates a preferred port configuration.

In a further development of this last-mentioned variant of the temperature control device according to the invention can also be provided that a dividing line between the first distribution and collection channel and the second distribution and collection channel between supply and discharge is bent, preferably approximately S-shaped, with the relevant distribution and Collecting channel runs along the dividing line and has a to the supply line or discharge towards changing cross-section. For example, the cross-section may flatten and / or broaden towards the inlet and outlet, while it is splitting and / or narrowing in the opposite direction. In this way, the temperature control effect can be influenced in a targeted manner via the flow conditions.

In order to further improve the tempering effect, in another development of the tempering device according to the invention, it can be provided 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 portion and merge at their respective first and second end portions in the respectively associated first distribution and collection channel or second distribution and collection channel. In this way, the tempering device according to the invention is supplemented by end-side tempering, which are formed substantially in analogy to the tempering in the tubular wall portion in order to further improve the tempering.

In order to enable the most space-saving arrangement of temperature control device according to the invention, another embodiment provides that the corrugated region is formed such that wave crests of the corrugated region in wave 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 suitably designed temperature control according to the invention can be arranged closely adjacent (quasi-toothed) by quasi nesting in the region of their wave crests and wave troughs.

It has proved to be particularly advantageous to further develop the tempering device according to the invention in such a way that two different variants thereof exist, which essentially differ from one another only with respect to an axial position of the corrugated region or the 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 device according to the first variant and a tempering device according to the second variant are plugged together with their wave crests and their troughs, as described above, this offset can be compensated with respect to the axial position of the corrugated areas just so that - with the same overall length - no 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 device according to the invention provides accordingly that at least one copy each of the two differently configured 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 are engaged , The achievable advantages have already been mentioned above.

In a further development of a tempering device according to the invention, the tubular wall portion has two preferably diametrically opposed corrugated areas and two preferably diametrically opposed distribution and collection channels, can still be provided that at least two tubular wall sections arranged parallel to each other 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 arises between the two tubular wall sections another tubular line section for receiving an electric module, in turn, except for electrical connection contacts or a drive shaft thereof. By cleverly connecting two spaced-apart temperature control devices, a further temperature control device is thus provided in a region between these temperature control devices, so that an extremely compact arrangement results for accommodating a multiplicity of electric modules.

According to another aspect, the invention also relates to an electric module, in particular a battery module or an electric motor, with a temperature control device 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 device are firmly connected to each other, in particular by cohesive connection in the region of wave troughs in the corrugated region and / or in the further corrugated area. This can be counteracted in battery cells deformation by chemical and thermal influences.

A first development of the electric module according to the invention, preferably in the form of an electric motor, comprises a sleeve-shaped, in particular substantially straight, circular-cylindrical module housing, which module housing is closed on at least one side, preferably on both sides, by means of a cover plate or a bearing plate, wherein on the outside of the module housing the temperature control device is arranged and wherein the module housing, the cover plate or the bearing plate and the jacket of the temperature control device are connected together in a fluid-tight manner, in particular cohesively and / or non-positively. This results in a manufacturing technology favorable overall arrangement.

According to another development of the electric module according to the invention can be provided that the cover plate or the bearing plate has a circumferential axial projection with which he / he radially overlaps the module housing and the jacket. The projection can serve as an axial stop for the stator of an electric motor.

According to yet another development of the inventive electric module can be provided that the cover plate or the bearing plate for mounting stator and / or rotor of an electric motor divided or divisible, preferably in an outer cover part / bearing plate part (ring member) and a (removable) inner cover part / bearing plate part.

According to a preferred embodiment of the inventive electric module can be provided that the cover plate or the bearing plate is designed as a bearing shell for supporting an output shaft or the like., Or is connected to such a bearing shell, preferably cohesively. This results in a space and cost functional integration.

According to another preferred development of the electric module according to the invention can be provided that the module housing is made of aluminum or steel, preferably in a thermoforming process to allow a simple and cost-effective production.

According to yet another preferred development of the electric module according to the invention can be provided that the cover plate or the bearing plate and / or the bearing shell is formed as a cast or forged part. This can be done in a single manufacturing step, the fluid-tight connection of temperature control, module housing and cover plate or end shield, e.g. by friction stir welding or the like

To be extremely advantageous, an arrangement of at least two electric modules has proven with a tempering, which tempering at least each includes a copy of the two differently designed variants, which are arranged as defined above adjacent and engaged, in each of the two differently shaped Variants each an electric module is arranged.

Also highly preferred is an arrangement of at least three electric modules with a tempering, in which between the two tubular wall sections, a further tubular conduit section is formed, in which in each case an electric module is accommodated in the two tubular wall sections and in the further tubular line section.

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.

5 now shows in longitudinal section a detail of a tempering device according to the invention, 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 present invention, a tempering medium or tempering fluid is introduced 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 according to the invention (tempering bellows) 10 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 symbolically represented. 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 suggest 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 device according to the invention, 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 may be composed of a plurality of partial shells or half-shells, as by corresponding joint lines VL is symbolized. In this way, the individual components of the sheath can be manufactured in a simple and cost-effective manner as deep-drawn parts, which then (cohesively) to the sheath 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 connecting piece, without the invention being limited thereto.

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 development of the temperature control device according to the invention 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 respectively 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 devices according to the invention arranged offset 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 dissipated amount of heat.

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 velocities v ₁ and v ₂ , which may 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 tempering 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 lie 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, if the different cooling currents are fed in opposite directions so 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.

26 shows a perspective view of a further embodiment of the temperature control device according to the invention. This has a total of approximately the shape of a straight circular cylinder and is at their ends with one cover element (bearing plate) 11 ' locked. reference numeral 11b again denotes the in the sheath 11 the temperature control device formed wave crests. As 26 can still be seen, are the supply line 13 or the derivative 14 of which in 26 due to the selected representation only one can be seen, arranged approximately centrally with respect to a longitudinal axis of the temperature control device. The wave crests are at their ends to the supply line 13 or derivative 14 curved, the curvature being stronger, the farther on the wave crest 11b from the supply line 13 or derivative 14 is removed. Overall, this results for the wave crests 11b in the area of their ends a pleasant fan-shaped course.

27 shows a substantially the representation in 26 corresponding embodiment in another presentation format.

In 28 is a frontal plan view of an electric module 20 shown, which specifically as Electric motor is formed. The electric module 20 has a tempering device according to the 26 and 27 is trained. reference numeral 20c denotes the output shaft of the electric motor.

In 29 is the electric module 20 shown in longitudinal section and partially enlarged. The output shaft 20c of the electric module 20 is in camps 50 stored, in turn, in bearing shells 51 are arranged in the bearing plate 11 ' go over or part of the end shield 11 ' are. The bearing shells 51 and the end shield 11 ' can be integrally formed or manufactured as separate components and then connected (cohesively). reference numeral 30 denotes the rotor and reference numerals 40 the stator of the electric motor. The cutting plane in 29 is chosen so that they - as shown - through the supply line 13 and derivative 14 as well as the associated distribution and collection channels 12.1 . 12.2 extends. From the copied-in detail magnification is still recognizable that the electric module (the electric motor) 20 outside a module housing in the form of a straight circular cylinder has, which module housing by the reference numeral 60 is designated. The bearing plate 11 ' has an axial projection at its outer edge 111 on, the sheath 11 the temperature control device and the module housing 60 radially overlaps, as shown. In a connection area at reference numerals V are module housing 60 , Sheath 11 and end shield 11 ' together preferably cohesively connected to each other, for example, welded, soldered or glued. In this way, in a single processing step for closing and allowing a temperature of the electric module 20 be taken care of.

The module housing 60 may be formed in a metal, preferably in aluminum or in steel. At the bearing shells 51 or end shields 11 ' it can be cast or forged parts. The same applies if necessary for the bearing shells 51 ,

In 30 is an alternative embodiment of the electric module 20 or the temperature control device shown. Here are supply line 13 and derivative 14 essentially offset on a line parallel to a longitudinal axis of the arrangement or in the direction of this longitudinal axis to each other. The supply line 13 and the associated first distribution and collection channel 12.1 , which at the relevant reference numeral below the with 11 designated sheath is located on the derivative 14 and the associated second distribution and collection channel 12.2 by a substantially S-shaped dividing line TL separated, as can be seen from the perspective view in 31 can be removed. The wave mountains 11b the sheath 11 the tempering are in turn at their ends slightly towards the respective distribution and collection channel 12.1 . 12.2 or the associated supply line 13 or derivative 14 curved towards, as in 31 shown. As the presentation in 31 only hinted at, widening a cross section of the distribution and collection channels 12.1 . 12.2 towards the relevant supply line 13 or derivative 14 , wherein a clear height of the respective distribution and collection channel 12.1 . 12.2 can lose weight. Strictly speaking, this is the dividing line TL around a dividing surface, like the 30 and also the 31 good to see, because in this area the sheathing 11 flat on an underlying module housing (see reference numeral 60 in 29 ) is applied to a fluid intake region of the supply line 13 from a fluid intake region of the drain 14 to separate.

In 32 is an enlarged detail of the embodiment according to the 30 and 31 shown. For an explanation, see the detailed description of the 29 , in particular the local detail section be referenced to avoid repetition.
