Description

The invention relates to a temperature control device for an electrical module, in particular for a battery module or for an electric motor, according to the preamble of claim 1, comprising: a casing designed to accommodate the electrical module essentially completely, with the exception of electrical connection contacts and/or an output shaft thereof , which casing comprises a tubular wall section; in the tubular wall section at least one corrugated area, in which the casing has at least one first corrugation formed radially outwards with respect to a longitudinal axis of the tubular wall section, which first corrugation extends at least in sections transversely to a longitudinal axis of the tubular wall section and a boundary for a flow channel for forms a tempering fluid for tempering an electrical module to be accommodated in the casing.

With claim 10, the invention also relates to an electrical module with a temperature control device according to the preamble of claim 1, which electrical module has a housing that is accommodated within the casing and whose tubular wall section makes contact with its housing at least in areas, so that in the area of the first shaft a Flow channel for a tempering fluid for tempering the electrical module is formed between the casing and the housing.

In addition, the invention according to claim 15 relates to a method for controlling the temperature of an electronic module with a temperature control device according to the preamble of claim 1, which electronic module has a housing, or for controlling the temperature of an electronic module according to the invention.

From the DE 10 2018 109 420 A1 (hereinafter “DE'420”) discloses a temperature control device for an electrical module, in particular for a battery module or for an electric motor. 5 of this publication (corresponds to the enclosed 1a) shows a longitudinal section of a detail of such a temperature control device, which can also be referred to as “cooling bellows” or “cooling sleeve” or generally as “temperature control bellows”. A bellows regularly has - in addition to smooth-cylindrical connection ends - a tubular, corrugated wall section, which 5 of DE'420 is shown at reference numeral 10a. The entire temperature control device is denoted by reference number 10 . In the corrugated area 10a, it has a plurality of corrugations, of which in 5 DE'420, for reasons of clarity, only some of the respective wave crests of these waves are provided with the reference symbol 10b. The tempering bellows 10 surrounds a body 1 to be tempered (according to 5 DE'420 a so-called electrical module), in the area of its surface (lateral surface) 1a. The tempering bellows 10 lies in the area of its wave troughs 10c on said surface 1a. A temperature control medium or temperature control fluid is then passed through the flow space 4 defined between the body surface 1a and an inside of the temperature control bellows 10 . The temperature control bellows 10 is applied in the region of its corrugation troughs 10c to the surface 1a mentioned and is regularly fixed there in a materially bonded manner, for example by a thermal pressure bond under pretension and a weld seam. In this way, a mass flow slippage between adjacent flow spaces 4 can be prevented; In addition, the integral connection of the temperature control bellows 10 to the body 1 to be temperature-controlled can lead to a stiffening of the latter, which is particularly advantageous if the body 1 is designed in the form of a battery module or a battery cell (especially in the form of prismatic, deep-drawn or extruded battery cups). and may be desirable.

Although such a configuration is advantageous in many ways, it requires a relatively high input of energy and can lead to thermal distortion due to heating of the components.

The object of the invention is to provide a remedy in this regard and to specify a temperature control device, a temperature-controlled electronic module and an associated production method that requires less energy during production and that no thermal distortion is to be expected.

The object is achieved according to the invention by a temperature control device having the features of claim 1, by an electrical module having the features of claim 10 and by a method having the features of claim 15.

Advantageous developments are defined in the dependent claims.

A temperature control device according to the invention for an electrical module, in particular for a battery module or for an electric motor, has: a casing designed to accommodate the electrical module essentially completely, with the exception of electrical connection contacts and/or an output shaft thereof, which casing comprises a tubular wall section; in the tubular wall section at least one corrugated area, in which the casing has at least one first corrugation formed radially outwards with respect to a longitudinal axis of the tubular wall section, wel The first wave extends at least in sections transversely to a longitudinal axis of the tubular wall section and forms a boundary for a flow channel for a temperature control fluid for temperature control of an electronic module to be accommodated in the casing; the temperature control device is characterized in that the casing also has at least one second shaft, which is designed as an adhesive shaft and has at least one opening to the outside for this purpose.

An electrical module according to the invention with a generic temperature control device according to the preamble of claim 1, wherein the electrical module has a housing that is accommodated within the casing and the tubular wall section of which makes contact with its housing at least in areas, so that in the area of the first shaft there is a flow channel for a temperature control fluid to Temperature control of the electrical module is formed between the casing and the housing, is characterized in that a) the casing is formed according to the characterizing part of claim 1; and/or that b) the casing outside the first shaft is essentially smooth-walled and the housing has at least one channel-shaped recess in this area, which is designed as an adhesive channel and for this purpose has at least one opening to the outside, preferably through the casing .

There are therefore two basic variants, in one of which the adhesive wave is formed in the casing (variant a)), while in the other the housing of the electrical module has a (negative) wave or channel, with the casing preferably being designed with smooth walls ( Variant b)). In principle, however, it is also possible to combine a shaft of the casing and a channel of the housing, although this can mean increased production costs.

In the case of an electric motor, the housing can take the form of a stator housing or stator support.

A method according to the invention for temperature control of an electrical module with a temperature control device according to the preamble of claim 1, which electrical module has a housing, or for temperature control of an electrical module according to the invention includes: i) when using the temperature control device according to the preamble of claim 1, arranging the electrical module within the casing , whereby it contacts its tubular wall section with its housing at least in areas, so that in the area of the first shaft a flow channel for a tempering fluid for tempering the electronic module is formed between the casing and the housing, and is characterized by ii) in a according to the identifier of Claim 1 formed casing (11), filling the adhesive wave, ie the second wave through the at least one opening from the outside with a flowable adhesive, preferably epoxy, polyurethane, phenolic resin, polyimide or polyester, and / or iii) in a according to variant b) ouch sformed casing, filling the at least one adhesive channel, ie the channel-shaped recess through the at least one opening from the outside with a flowable adhesive, preferably epoxy, polyurethane, phenolic resin, polyimide or polyester, iv) curing or setting of the adhesive, and v) flowing through the first Shaft with a tempering fluid, preferably during operation of the electrical module.

The provision of the adhesive shaft or adhesive groove and its filling with adhesive according to the invention makes it possible to produce a temperature control device or an electrical module that requires less energy and does not have any thermal distortion to be expected. Epoxy, polyurethane, phenolic resin, polyimide or polyester is preferably used as the adhesive, without the invention being limited thereto.

Alternatively, the mentioned opening and the filling of an adhesive from the outside into the adhesive shaft or adhesive channel can also be dispensed with. The adhesive/sealant can then be introduced in the form of a sealing tape/adhesive tape, which expands after it has been introduced into the sealing groove/adhesive shaft and the casing and housing have been installed, thereby establishing contact with the electronic module.

For example, adhesive/sealing tapes based on polyurethane (PU), butyl or EPDM can be used. Sealing can take place via mechanical relaxation after previous pre-compression or reaction with atmospheric oxygen or moisture. One- or multi-component systems can also be used, which expand and cross-link, "harden" or seal as a result of a rise in temperature. For example, PU can be applied with added reaction retarders and only connects the parts to be joined after relative positioning within a defined time window under the optional influence of temperature and moisture.

A first development of the temperature control device according to the invention provides that the second shaft has at least one second opening. The second opening can serve as a vent and thus promotes the filling of the adhesive shaft or adhesive channel with adhesive.

A second further development of the temperature control device according to the invention provides that one opening and/or the second opening is/are conical and preferably tapers from the outside inwards. Such an embodiment facilitates the insertion of an adhesive device for filling in the adhesive.

Another development of the temperature control device according to the invention provides that the second shaft(s) has or have a defined width in the longitudinal direction, preferably between 2 and 10 mm, most preferably 3-5 mm. In this way, a preferred dimension of the adhesive connection can be defined and a corresponding security of connection can be achieved.

Yet another further development of the temperature control device according to the invention provides that the second shaft(s) has or have a defined height in the radial direction, preferably 0.1 to 3 mm, most preferably 0.2 to 0.5 mm. A preferred dimension of the adhesive connection can also be defined in this way and a corresponding security of connection can be achieved.

Another development of the temperature control device according to the invention provides that more than one first shaft is provided, with adjacent first shafts being spaced apart axially and the at least one second shaft being arranged axially between two first shafts. In this way, the adhesive shaft separates two flow channels for the tempering fluid from one another and can reliably prevent mass flow slippage.

Yet another further development of the temperature control device according to the invention provides that more than one second shaft is provided, preferably forming an alternating sequence of first and second shafts in the axial direction. This is a logical further development of the idea mentioned above and can prevent a mass flow slip even better.

A preferred development of the temperature control device according to the invention provides that a supply line and an outlet line for a temperature control fluid are arranged in fluid-conducting connection with the at least one first shaft. In this way, a temperature control fluid can flow through the first shaft in order to optimize the efficiency of the temperature control device.

An extremely preferred development of the temperature control device according to the invention provides at least one additional second shaft, which extends essentially, ie mostly in the axial direction, and preferably separates an area of the supply line from an area of the outlet line for a temperature control fluid in order to ensure a far-reaching flow around the encased area to care. Furthermore, this additional second shaft(s) can be used to connect to an end seal of the temperature control device.

In a further development of the electronic module according to the invention, according to variant a), the temperature control device can also be designed as described in detail above in connection with the second shaft(s) designed as an adhesive shaft(s).

In another development of the electrical module according to the invention, according to variant b), the adhesive channel(s) can be arranged and/or designed analogously to the second shaft or shafts. This relates in particular to the arrangement relative to the first waves and the width and height or depth of the adhesive channel(s).

A preferred development of the electrical module according to the invention provides that the second shaft or shafts is/are filled with an adhesive, preferably with epoxy, polyurethane, phenolic resin, polyimide or polyester or with an expandable or expanded adhesive tape, see above. This achieves a secure and intimate connection between the casing and the housing.

In general, the adhesive can be used for materially bonded, mechanically resilient connections and optionally for sealing. Within the framework of a design variant, the use of a pure sealing compound is also possible. In the present case, the term "adhesive" is also intended to cover "sealants".

An extremely preferred development of the electrical module according to the invention provides that the first shaft or shafts is/are filled with a temperature control fluid, e.g. water with and without additives. This allows the temperature control effect to be optimized. Suitable conveying and storage means can be present for the tempering fluid.

On the 1a was already pointed out in detail in the introductory part of the description.

1b corresponds to the representation in 31 the DE'420. This and its importance for the present invention will be discussed in more detail below.

2 shows in a partial longitudinal section a first embodiment of the temperature control device according to the invention, which is denoted overall by the reference numeral 1. Reference number 2 shows part of a housing of an electronic module, not shown in any more detail, for example the housing of a battery cell or the stator support of an electric motor. In the present exemplary embodiment, the housing 2 is in the form of a smooth-walled (circular) cylindrical sleeve, without the invention being limited thereto. The actual temperature control device 1 is formed by a (thin-walled) sleeve, preferably made of a metallic material, which is arranged radially on the outside around the housing 2 in the manner of a jacket. In 2 as well as in the following 3 and 4 L denotes the longitudinal direction (direction of a longitudinal axis) and R denotes the radial direction.

How to show in 2 removes, the casing or the temperature control device 1, which is designed to accommodate the electrical module substantially completely, has a tubular wall section with at least one corrugated area, in which area the casing has at least one first wave 1a formed radially outwards with respect to the longitudinal axis . This first shaft 1a extends transversely to the longitudinal axis, that is, into and out of the plane of the drawing, and forms an outer boundary for a flow channel 1d for a temperature control fluid (not shown) for temperature control of an electrical module accommodated in the casing, from which - as I said - only part of the housing 2 is visible. In addition to the first shaft 1a, the temperature control device 1 or the casing also has at least one second shaft 1b, which is specially designed as an adhesive shaft and has at least one opening 1c to the outside for this purpose. Adhesive can be introduced from the outside through the opening 1c in the area between the adhesive shaft 1b and the housing 2 in order to connect (glue) the temperature control device 1 and the housing 2 to one another in a defined material connection. For this purpose, the second shaft 1b preferably also has at least one second opening, not shown, through which the air contained in the adhesive shaft can escape to the outside when adhesive is poured in. How to 2 still removes, the opening 1c is conical and tapers in cross section from the outside inward in the radial direction, which facilitates the attachment of a tool for filling the adhesive.

In order to achieve a defined bonding of the temperature control device 1 and the housing 2, the second shaft 1b has a defined width B in the longitudinal direction L. The same applies to the height H in the radial direction R. In this way, together with the cross-sectional shape of the second shaft 1b, a defined adhesive surface results, which ensures that the temperature control device 1 and the housing 2 are securely bonded.

In addition to the temperature control device 1, the housing 2 is preferably also made of a metallic material, without the invention being restricted thereto. Aluminum, aluminum alloys and steel in particular come into consideration as suitable metallic materials.

The invention is not limited to 2 shown as an example cross-sectional shapes of the first shaft 1a and the second shaft 1b limited.

3 shows another embodiment of the temperature control device 1 according to the invention, which has several, in this case two, first shafts 1a and second shafts 1b. A second shaft 1b is always provided between two first shafts 1a, which are arranged at a distance from one another in the longitudinal direction L, without the invention being limited to such a configuration. This sequence of first and second waves can be repeated as often as desired in the longitudinal direction L; preferably, the terminal shaft in each case is a second shaft 1b. Advantageously in accordance with the design 3 is that the second shafts 1b, after they are filled with adhesive, ensure efficient suppression of a possible mass flow slip (of the tempering fluid) between the first shafts 1a and the flow spaces 1d. In this way, a particularly good temperature control effect can be permanently ensured.

Otherwise, here and in the following, the same reference symbols designate the same elements or at least elements with the same effect.

In 4 Another development of the temperature control device 1 according to the invention is shown, in which the bonding between the temperature control fluid 1 and the housing 2 does not take place in the area of a second shaft of the temperature control device 1, but in the area of a groove-like or channel-like depression 2a of the housing 2. Again, on the temperature control device 1 An opening 1c is provided in the area of the adhesive channel 2a in order to be able to inject adhesive into the adhesive channel 2a in a simple manner from the outside. In principle, however, it is also possible to provide a corresponding injection opening on the housing 2 in order to inject adhesive from the inside into the adhesive channel 2a. However, under certain circumstances, this can entail disadvantages in production.

It is not necessary for the housing 2 to be drawn inwards in the radial direction R in the area of the adhesive channel 2a, so that the clear inner diameter of the housing 2 is reduced in this area. It is also within the scope of the invention to provide the adhesive channel 2a without reducing the clear housing cross section in this area—for example, by simply removing material from the housing 2 on the outside in the area of the adhesive channel 2a.

Also in accordance with the design 4 At least two openings corresponding to reference numeral 1c can be provided in the temperature control device 1 in order to allow air to escape when injecting adhesive.

Analogously to the design in 3 can also at the subject of 4 several first shafts 1a can be provided spaced apart in the axial direction L, with an adhesive channel 2a being arranged between each two first shafts 1a in order to achieve the same advantages as above with reference to FIG 3 described.

The width and height (depth) of the adhesive channel(s) 2a can be designed like the second shaft 1b according to FIG 2 .

The first shaft 1a or the first shafts 1a are preferably in accordance with the 2 until 4 operatively connected to a feed line and a discharge line (not shown) for a tempering fluid in order to introduce the tempering fluid into the relevant flow chamber 1d and to discharge it again from the flow chamber 1d. The flow spaces 1d can be operatively connected, as shown in FIG 1b is explained.

Another development of the temperature control device according to the invention will now be based on the 1b explains which - as already noted - the 31 from DE'420.

As can be seen from the perspective view in 31 of DE'420 (cf. the attached 1b) can be seen, the crests 11b of the casing 11 of the local temperature control device (temperature control device) of an electrical module 20 are slightly curved at their ends towards a relevant distribution and collection channel 12.1, 12.2 or an associated supply line 13 or discharge line 14, as shown. As can only be inferred from the illustration, a cross-section of the distribution and collection channels 12.1, 12.2 widens towards the feed line 13 or discharge line 14 in question, with a clear height of the distribution and collection channel 12.1, 12.2 in question being able to decrease. Strictly speaking, the separating line TL between the distribution and collecting ducts 12.1, 12.2 is a separating surface, because in this area the casing 11 rests flat against a module housing underneath, in order to separate a fluid intake area of the supply line 13 from a fluid intake area of the discharge line 14.

The mentioned further development of the present invention provides for the temperature control device to be analogous to the embodiment 1b train and along the dividing line TL according to 1b to provide a (further) adhesive shaft (second shaft) or adhesive channel which covers the area of the in 1b shown supply line 13 from the area in 1b derivative 14 shown separates. How to 1b can still be seen, the dividing line TL on the end faces of the electric module 20 shown merges into a circumferential, end-side seal of the temperature control device relative to the internal housing of the electric module. Within the scope of the present invention, this can be achieved by a corresponding configuration or arrangement of the adhesive shaft or adhesive channel.

In the context of the present invention, the 1b The wave crests 11b of the casing 11 shown correspond to the wave crests of the first waves 1a (cf. 2 until 4 ). According to the prior art, the casing 11 touches the outside of the housing of the electrical module in the area of the intervening wave troughs (not labeled) and can be fastened here in particular with a material connection (cf. 1a) . According to the present invention, it is now provided that the already mentioned adhesive shafts 1b or adhesive inners 2a be provided in these connection areas to the electronic module housing. Their arrangement and design can otherwise be done as per 1b known from the prior art, so that the prior art undergoes an advantageous development.

This is achieved by at least one additional second wave, which is analogous to that Separating line TL extends essentially in the axial direction and preferably separates an area of the supply line 13 from an area of the discharge line or discharge line 14 . In a further development, the additional second shaft mentioned can also ensure a connection to the front seals of the temperature control device, as shown.
