DATA PROCESSING MODULE WITH HEAT INSULATING HOUSING AND HEAT TRANSFER ELEMENT

The invention relates to a data processing module with an electronic data processing unit for digital data and with a housing in which the

Data processing unit in a predetermined

Operating position is arranged, wherein the

Data processing unit of one in the housing

is arranged surrounded heat-insulating material, wherein in the housing a made of a thermally conductive solid heat transfer element is arranged, which forms a heat transferring connection from a heat conductive housing interface in a housing wall to the distance from the interface arranged data processing unit, so that waste heat

Data processing unit can be removed via the heat transfer element from the housing.

Reliable processing, and in particular storage and storage of digital information, is of great importance in many areas. Most electronic data processing systems are designed for indoor operating conditions and can withstand neither humidity nor large humidity

Temperature fluctuations. If unusual loads or operating conditions occur, such as a high heat impact due to a fire or contact with water during fire extinguishment, the - -

Data processing equipment damaged and the stored data often can not be read or

continue to be used. In many cases, the

digital information may be copied and stored elsewhere in order to provide reliable access to that information in the event of damage or failure of a data processing system

enable. Suitable backup solutions may copy the copied information in addition to the

Data processing system connected storage units or often far away

Store storage units to which the copied data is wired or wireless

be transmitted.

By means of a suitable data backup, in particular in a spatially remote storage unit or in the cloud, the digital information of a

Data processing system can be reused even after their damage or failure, so that, for example, data processing systems with multiple

Data processing systems, each accessing the data stored in a separate storage unit, can be operated fail-safe. However, this requires that if there is a threat of failure of a single data processing system both enough time available as well as the ability to copy the digital information and transmit it to a remote storage unit.

From practice, data processing systems or individual data processing modules are known, the one - -

additional work for demanding operating or environmental conditions. So can

Data processing equipment such as portable

Computer or mobile devices are designed to be particularly impact and break resistant or have a separate seal against moisture or be waterproof. By

additional insulation and insulation can be used

correspondingly protected data processing systems or modules survive at least over a period of time a greater heat impact. In US 2004/0012316 AI, US 5,479,341 or WO 2007/055716 A2 are various

Embodiments of data processing modules, or

Data storage units are described, which are arranged in a housing and protected by various measures against fire or water.

Such as well protected against extraordinary environmental conditions data processing modules are currently used, for example, in a so-called black box, a storage device for digital data stores information during operation of an aircraft or a vehicle, in the event of an accident, a subsequent evaluation of the recorded

To allow information and a reconstruction of the accident.

The shielding of the data processing unit arranged in a housing from the effects of heat, which is in many cases particularly important, usually requires the most efficient and effective possible insulation and insulation of the data processing unit, so that there is no heat - -

to penetrate from outside the case and the

Data processing unit can damage.

However, if the data processing unit itself generates heat during operation, that heat must be dissipated to overheat the

Prevent data processing unit during normal use. From practice it is known that a heat transfer element the

Data processing unit connects to the surrounding housing or with a housing interface arranged on the housing in order to be able to dissipate the heat generated by the data processing unit during operation, despite the insulation, via the heat transfer element. However, for example, in case of fire or at high

Outside temperatures via the heat transfer element also heat from outside the housing to the

Data processing unit transferred, so that a

any existing insulation is ineffective. In a thermally insulated or insulated housing, therefore, only such data processing units can be used, which only produce such a small amount of waste heat during operation, despite the thermal insulation does not overheat and damage the

Data processing unit can lead. But also at

Data processing units that produce only a small amount of waste heat at current scales, this can

Heat generation in a small footprint lead to problems, for example, if the usable interior of a housing is only slightly larger than the data processing unit or a large number of data processing modules are arranged and operated spatially close together. - -

In a data processing module described, for example, in US Pat. No. 5,623,597, a passively cooled

Data processing unit in case of external

Displaced heat action together with the heat transfer element away from the housing wall in the interior of the housing and then by a if necessary introduced heat insulating material of the

Housing wall thermally insulated. In a further embodiment variant described in this document, an active cooling of the data processing unit is provided in the housing, wherein a cooling fluid by a heat generated by the data processing unit

Coolant channel discharges to the outside and the

Coolant channel with an external heat effect

can be closed to prevent heat transfer from the outside into the housing inside. Such a data processing module requires a comparatively large interior in the housing in order to enable a displacement of the data processing unit in the housing or an active cooling of the data processing unit with a cooling fluid. In addition, such requires

Data processing module active control and

Actuating device, which in case of need the

Data processing unit relocated or the

Coolant channel closes. However, a data processing module with a controlled actuator is not suitable for a black box, which should take up as little space. In addition, could be an active

Actuator may be damaged in a sudden event, such as an accident, so that the of the actuator - -

causing thermal foreclosure of the

Data processing unit is no longer or only insufficiently done.

In a black box as possible electronic

Components used that have no or hardly any waste heat

generate, and these components together with the insulation or insulation in a sufficiently large housing

arranged to overheat the

To avoid data processing unit both during operation and in the event of an accident of the vehicle.

It is considered an object of the present invention

a data processing module in which the data processing unit is connected via a heat transfer element with a housing interface, so

to design that the most effective protection of the data processing unit arranged in the housing can be achieved. In addition, the space required for this should be as low as possible.

This object is achieved in that the heat transfer element between the housing interface and the data processing unit comprises a separation device, the heat transferring connection of the heat transfer element between the housing interface and in the in the case of excessive heat input from the housing interface to the data processing unit

Operating position arranged data processing unit interrupts. During normal operation, the heat generated by the data processing unit via - -

the heat transfer element to the housing interface and away from the data processing unit are removed from the housing. By the separation device is achieved that in the event of an extraordinary heat from the outside, the heat transfer through the

Heat transfer element interrupted and thereby

prevents excessive heat input from the outside directly to the data processing unit

can be transferred. After the interruption of the

Heat transfer element is the

Data processing unit protected by the thermal insulation in the housing and this thermal insulation is no longer bypassed by the heat transfer element.

The heat transfer element may be made of any material which, if possible, a good

Heat transfer allowed. Suitable materials are, for example, metals. The heat transfer element requires little space and can save space, for example, as a flat strip or as a flexible metal strip

be formed so that the data processing unit can be almost completely surrounded by an insulating material. A displacement of the data processing unit within the housing is at an outer

Heat is not required. The thermal

Insulation can be permanently arranged in the housing and designed such that the highest possible insulation. Also for these reasons, a very effective thermal insulation can be effected, which only a small

Requires space and protects the data processing unit from external heat. - -

The separating device can be designed such that the separating device is activated as needed and the

Can interrupt heat transfer element. For this purpose, a temperature sensor may be arranged, for example, in the region of the housing interface or on an outer side of the housing, the measuring signals of which are evaluated and trigger an active actuation of the separating device, if a threshold value for the temperature is exceeded. The separating device may, for example, have a displaceable separating element, which is the

Cut heat transfer element or displaced a portion of the heat transfer element, so that the

Heat transfer element is broken and no

Heat transfer can take place more. The energy for active actuation of the separator may be provided in an electrical energy storage device or in a capacitor, for example, which are disposed within the housing and may optionally be charged during normal operation of the data processing unit.

According to one embodiment of the inventive concept it is provided that the separating device has an electrically operated actuating device, with which the heat transfer element is interrupted. The electrically operated actuating device can, for example, have a separating element designed as a cutting edge or cutting disk, which does not have any or only a small amount

thermally conductive material such as plastic or ceramic. The separating element can be electric

driven, for example, driven by an electric motor drive and can be relocated, so that the _ _

Separating element upon actuation of the

Actuator the heat transfer element

severed and the heat transferring compound

interrupts.

It is also possible that the electrically operated actuator a displaceable switching or

Has latching element. The heat transfer element may for example have a production-related or by means of a spring device biased separating element, which is arranged on or in the heat transfer element, that the separator without the action of external forces in such a vorspannungsfreie

Rest position shifted or deformed, that no

heat transferring compound via the

Heat transfer element is possible. By bias, the separator is in contrast to a

Heat transfer position shifts or deforms that a heat transferring compound through the

Heat transfer element allows and causes.

The separating element can be retained by means of a switching element or a latching element in the prestressed arrangement or in the heat transfer position. Once the switching element or locking element of the electric

operated actuator is displaced,

For example, by an electric motor actuation or by the electrical activation of a switch or latching means, the biased separating element is released and can be in the bias-free rest position

return, whereby the heat transfer is interrupted. - -

A particularly advantageous embodiment of

According to the invention, it is provided that the electrically operated actuating device a

Electromagnet device, with which during operation of the electromagnetic device, the

made heat-transmitting connection and with which by switching off the electromagnet means, the heat-transmitting connection via the

Heat transfer element is interrupted. The

Electromagnet device may comprise a magnetic or provided with a magnet separator, which can be retained in a heat-transmitting arrangement, if and as long as the separator is attracted to the magnetic field generating magnetic field. As soon as the electromagnet device is switched off or is no longer operated as a result of a termination of the electrical supply and no more magnetic field is generated, the separating element can be transformed by a suitably generated bias into a heat transfer

shifting arrangement or in a

appropriate shaping deformed. In this way it can be achieved that even in the case of a sudden or unexpected interruption of the power supply, as may occur, for example, in a fire or accident, the heat transfer element and thus a

unwanted heat transfer to the

Data processing unit is reliably interrupted.

The activation or actuation of the electrically operated actuating device can via a control device - -

carried out, which is connected to a temperature sensor and activates or actuates the actuating device as soon as a measured value measured with the temperature sensor exceeds a predetermined threshold value. It can the

Threshold can be set almost arbitrarily and very precisely.

It is also conceivable and with regard to the most reliable interruption of heat transfer

advantageous that the separator without a

additional power supply can be activated and that

Can interrupt heat transfer element. For this purpose, it is provided according to a particularly advantageous embodiment of the inventive idea that the separating device has a form-changing by heat influence separating element, wherein by a change in shape of the

Separating element, the heat transfer element is interrupted. A separate activation and the one for this

required components are not required. Once the ambient temperature exceeds a predetermined

Threshold increases and the generated thereby

Heat action on the separator whose form changed, can be interrupted with the separating element, the heat transfer element. In this case, for example, a region or a portion of the heat transfer element can be displaced, so that the heat transfer is prevented. It is also possible that the heat transfer element has a weak point formed as a predetermined breaking point and the separating element in the shape change the

Heat transfer element at the point of weakness

cut so that the heat transfer along the severed heat transfer element is prevented. - -

By using a suitable separator, which changes its shape when exposed to heat, can without a separate temperature monitoring and

Control and in particular without a separate

Actuating the heat transfer element

interrupted and an undesirable heat input of

be prevented outside the housing to the data processing unit out. However, it is also conceivable that an electrically operated actuator is combined with a first and optionally biased separating element with a second form-changing by heat action separator, which interrupts the heat transfer without a separate actuator as soon as a threshold for the temperature is exceeded.

According to an optional embodiment of the

The idea of the invention is that the

Separating device comprises a bimetal strip whose shape below a threshold temperature

allows heat transfer connection from the housing interface to the data processing unit and above a threshold temperature assumes a different shape, so that the heat-transmitting

Connection from the housing interface to the

Data processing unit is interrupted. A bimetal strip is commercially available and inexpensive. The bimetallic strip may be designed such that the bimetallic strip during the intended use of the data processing module in a designated temperature range to, for example, 80 ° C in the - -

Has substantially planar shape. The

planar bimetal strips may form a portion of the heat transfer element. As the ambient temperature rises above a threshold temperature set, for example, at 100 ° C., the bimetallic strip changes shape and has an increasing curvature with increasing temperature, so that at least one end portion of the bimetallic strip bends away from the adjacent region of the heat transfer element and thereby Heat transfer breaks. The curving one

Bimetal strips can also be applied to a section of the

Act heat transfer element and the

Move heat transfer element away from the data processing unit to heat transfer over the

To prevent heat transfer element.

According to one embodiment of the inventive concept can also be provided that the

Heat transfer element has at least two spaced apart heat transfer sections and a separator made of a thermally conductive material, the spaced heat transfer sections together thermally conductively, the separator melts above a threshold temperature and the

Heat transfer along the heat transfer sections interrupts. The separating element can be made of fused solder

be prepared, wherein the melting solder comprises a metal such as bismuth or a metal alloy, which

comparatively low temperatures of, for example, 110 ° C melts. Once the temperature is up

Threshold temperature of 110 ° C, the separator melts, whereby the heat-transferring compound of - -

two heat transfer sections of the

Heat transfer element destroyed and the heat transfer is interrupted.

Optionally, it is provided that the heat transfer element has a weakening separation point and a through

Heat change shape-changing separator above a threshold temperature changes its shape and thereby the heat transfer element to the

Weakening separation point separates and thereby the

interrupts heat transferring connection. For the

Cutting the heat transfer element requires only a comparatively small space. The

Weakening separation point can along the

Heat transfer element may be disposed at any position within the housing. Optionally, it may be provided that the attenuation separation point has a sufficient distance from the data processing unit to prevent unwanted mechanical stress on the data processing unit as a result of deformation of the shape-changing separation element or during the process

To be able to reliably avoid severing the heat transfer element.

The weakening separation point can, for example, a

Perforation in the formed as a metal foil

Be heat transfer element. It is also possible that the weakening separation point is formed by a constriction or taper in the heat transfer element. A two- or multi-part design of the heat transfer element is conceivable, the individual sections during normal operation - -

abut each other and can transfer heat. The

Weakening separation point can then be formed by a transition of a first section to a second section, wherein the separating element, the first section

displaced or deformed, so that the first portion has no contact with the second portion and heat transfer is prevented.

According to one embodiment of the inventive idea, it is provided that the shape-changing separating element has an intumescent material which expands upon heating and thereby acts on one of the

Weakening separation adjoins the deformation portion of the heat transfer element, so that the

Deformation deformed section and the

Heat transfer element is interrupted at the weakening separation point.

According to an alternative embodiment of the inventive concept, it can also be provided that the shape-changing separating element has a heat-shrinkable material which contracts when heated and thereby adjacent to the weakening separation point

Deforming section of the heat transfer element

acts so that the deformation portion is deformed and the heat transfer member is interrupted at the weakening separation point.

In both cases, the change in shape of the separating element forced by the action of heat is used to transfer the heat transfer element to the space provided

Severing weak point and the - -

Interrupt heat transfer. The separator may be directly adjacent to or fixed to the heat transfer element. It is also possible that the separating element acts indirectly on the heat transfer element and, for example, a cutting edge or a

Shifting element displaced so that the

To cut heat transfer element.

According to an advantageous embodiment of

The idea of the invention is that the

shape-changing separator is a shrink tube, one adjacent to the weakening separation point

Surrounding deformation portion of the heat transfer member and which contracts when heated, thereby contracting the deformation portion of the heat transfer member, thereby the heat transfer member is interrupted at the Schwächungspennstelle. The

Deforming portion of the heat transfer element is formed for example as a metal foil. The

Shrink tubing surrounds the deformation section. When heating the shrink tube over a

Threshold temperature, the shrink tube pulls

together, so that the deformation section is also pulled together and thereby torn off at the weakening separation point. The deformed together with the shrink tube deformation section has no contact with one beyond the weakening separation

adjacent area of the heat transfer element, so that the heat transfer is interrupted. A shrink tube with suitable properties, in particular with regard to the threshold temperature and the heat-related deformation is commercially available and inexpensive. The one for one - -

Such configuration of the partition element required space is small.

It has been found that in an embodiment of the data processing module according to the invention it is possible to effect effective heat protection in a very small housing for a data processing unit such as a microprocessor or a storage unit. For example, a storage device that can store several gigabytes of digital data can be housed in a 3.5-inch hard-disk enclosure and protected from heat. This makes it possible to use the present invention protected against heat data processing modules in place of the standard 3.5-inch hard disks or storage units. In data processing systems, the unprotected

Disk housing removed and replaced by protected according to the invention data processing modules, so that a retrofitting of data processing systems is possible.

In an advantageous manner, it is optionally provided that at least one electrical connecting line is arranged on or in the heat transfer element, which electrically conducts the data processing unit with the data processing unit

Enclosure interface connects. The electrical

Connecting cables can be placed on a surface of the

Be transferred heat transfer element. In a forced by heat separation of the

Heat transfer element, the electrical

Connecting lines are also severed to also unwanted heat transfer via the electrical - -

Interrupt connection lines through the interior of the housing to the data processing unit. In addition, by interrupting the electrical

Connecting cables additionally prevent unwanted voltage peaks on the

Data processing unit act and this could possibly damage or destroy.

The heat transfer element may be at least partially made of an electrically conductive material. The electrically conductive material may be the electrical

Form connecting lines. The electrically conductive material may also be on an outside of the

Heat transfer element, for example, vapor-deposited or printed. If the heat transfer element is made of a metal, an electric

Appropriately, it can be provided that the

Data processing unit has a storage device for digital data. According to a special

advantageous embodiment of the inventive concept is provided that the memory device comprises a solid-state disk. An inventive

Data processing module with a storage device for digital data is extremely advantageous for use as a black box, for example, in aircraft as a flight data recorder or any vehicle as

One in Figures 1 to 14 in different

Embodiments illustrated data processing module 1 has a housing 2, in which a

Data processing unit 3 is arranged. The

Data processing unit 3 is approximately centrally positioned in an inner space 4 of the housing 2 and

established. The data processing unit 3 is almost completely surrounded by a thermal insulation material indicated only schematically in FIG. The thermal insulation material 5 forms a thermal insulation and reduces a - -

Heat transfer between the environment outside the housing 2 and the data processing unit 3. Ideally, in an exceptional heat exposure, for example by a fire accident, the data processing unit 3 are thermally shielded and protected by the thermal insulation material 5, so that the data processing unit 3 survives the fire accident and then in the

Data processing unit 3 stored digital data can still be read and reused. The thermal insulation material 5 may additionally provide protection against mechanical stress and possibly also

Provide moisture. It is also possible that in addition to the thermal insulation material 5, a separate protective device or protective cover is provided within the housing in order to protect the data processing unit 3 from shocks and vibrations and from moisture.

The data processing unit 3 may comprise, for example, a microprocessor or a data storage unit which generate heat during the intended operation which must be dissipated by the data processing unit 3 in order to prevent undesired overheating of the data

Data processing unit 3 to avoid. For this purpose, the data processing module 1 a from a

thermally conductive solid produced

Heat transfer element 6, which is heat-transmitting both connected to the data processing unit 3 and with a arranged on the housing 2 housing interface 7. The heat generated by the data processing unit 3 during operation can be transferred via the

Heat transfer element 6 to the housing interface. 7 - -

transferred and discharged there in a suitable manner, for example by cooling fins or a cooling medium, which is guided past the housing interface 7. The heat transfer element 6 penetrates the

Data processing unit 3 surrounding thermal insulation material 5 and allows a beneficial during operation

Heat transfer from the data processing unit 3 to the surrounding housing 2 and into the environment. However, as soon as the ambient temperatures rise above a predetermined threshold and must be feared that by a

Heat transfer from outside the housing 2 to the

Data processing unit 3 out overheated and

could be damaged, the heat transfer via the heat transfer element 6 according to the invention

interrupted. With the help of no more of that

Heat transfer element 6 bypassed thermal insulation material 5 can then the data processing unit 3 before a

to be protected from excessive heating.

In that shown in Figures 1 and 2

Embodiment, the heat transfer element 6 has two spaced apart

Heat transfer sections 8, 9, wherein a first heat transfer section 8 is connected to the housing interface 7 and a second heat transfer section 9 is connected to the data processing unit 3. A gap 10 between the two heat transfer sections 8, 9 is bridged by a contact bridge 11. The

Contact bridge 11 is made of a fusible link and melts as soon as the temperature over one through the

Composition of the melt slot predetermined threshold - -

increases. A threshold temperature of, for example, 90 ° C or 110 ° C may be appropriate to one hand to allow undisturbed as possible operation and

on the other hand, at an unexpected temperature rise outside the housing 2, for example at a

Fire accident the heat transfer reliable too

before the data processing unit 3 is seriously damaged. In Figure 1, the contact bridge 11 is shown at low temperatures and allows heat transfer through the two

Heat transfer sections 8, 9, while in Figure 2, the contact bridge 11 is melted due to high ambient temperatures, so that the gap 10 between the two heat transfer sections 8, 9 is no longer bridged and the heat transfer through the

Heat transfer element 6 is interrupted.

In the illustrated in Figures 3 and 4

Embodiment, the heat transfer element 6, a portion 12 which is bridged by a bimetallic strip 13, which serves as a separating element. The

Bimetal strip 13 is formed such that the

Bimetal strip 13 at normal room temperatures in

Essentially planar and has a straight course, so that the bimetal strip the two

Heat transfer sections 8, 9 heat transfer

connects together, as shown in Figure 3. Once the outside temperature is above a predetermined

Threshold increases bends the bimetallic strip 13, so that a free end 14 of the bimetallic strip 13 from the associated heat transfer section 9 is removed and the heat transfer through the - -

Heat transfer element 6 interrupts, as shown in Figure 4. Unlike the previous one

described embodiment, the bimetallic strip 13 may be designed reversible and allow the heat transfer through the heat transfer element 6 again following a brief heat from the outside and a subsequent cooling, so possibly the use of the invention

Data transmission module 1 can be continued.

In the embodiments illustrated in the following figures 5 to 10, the heat transfer element 6 each have a Schwächungspennstelle 15, at which the heat transfer element 6 in the case of an outer

Heat should be severed. The

Weakening separation point 15 can be formed for example by a perforation, by notches or by a taper of the heat transfer element 6. It is also possible that the heat transfer element 6 is already severed at the weakening separation point 15, but the adjacent regions are close to each other during normal operation and form a heat-transferring contact.

In the illustrated in Figures 5 and 6

Embodiment, the heat transfer element 6 a deformation portion 16. The

Heat transfer element 6 is above the

Deformation section 16 across flexible and, for example, sufficiently thin, so that the

Heat transfer element 6 in the region of

Deformation section 16 by the action of a - -

heat shrinkable material can be deformed. Around the deformation portion 16 is a shrink tube 17 made of a suitable heat-shrinkable material

arranged, which the heat transfer element 6 in

Area of the deformation section 16 surrounds.

During normal operation hampered

Shrink tube 17 does not transfer heat through the uninterrupted heat transfer element 6

(Figure 5). Once the outside temperature is over one

Threshold increases, the shrink tube 17 contracts. In this case, the deformation portion 16 is contracted until initially the heat transfer element

6 demolished at the weakening separation point 15 and

is interrupted, and then a then free end 18 of the deformation portion 16 of the

Data processing unit 3 away to the housing interface

7 is pulled, so that a further heat transfer via the now interrupted heat transfer element 6 is prevented (Figure 6).

In the other two exemplary

Embodiments, which are shown schematically in Figures 7 and 8 and 9 and 10, will

Heat transfer element 6 in the region of

Weakening point 15 by in the area of

adjoining deformation portion 16 occurring impact of a heat-form-changing material separated and interrupted when an outside temperature rises above a predetermined threshold and

excess heat would be transferred from the housing interface 7 to the data processing unit 3. - -

In the illustrated in Figures 7 and 8

In the exemplary embodiment, the separating element has a tension element 19 with a heat-shrinkable material 20. As soon as this is in contact with the housing 2

heat shrinkable material 20 over a given

Warms up the threshold, it pulls out

heat shrinkable material 20 together, so that by the tension member 19 a transverse to the orientation of the

Heat transfer element 6 directed tensile force is exerted on the heat transfer element 6 and the

Heat transfer element 6 is interrupted at the weakening separation point 15. In the illustrated in Figures 9 and 10

In the exemplary embodiment, the separating element has a pressure element 21 with an intumescent material 22. As soon as the intumescent material 22, which is in contact with the heat transfer element 6, has a predetermined temperature

As the threshold heats up, it expands

intumescent material 22 out, so through the

Pressure element 21 a transverse to the orientation of the

Heat transfer element 6 directed compressive force is exerted on the heat transfer element 6 and the

Heat transfer element 6 is interrupted at the weakening separation point 15.

In FIGS. 11 to 14, by way of example only, two different variants of the data processing module 1 with a respectively differently configured electrically operated actuating device 23 are schematically illustrated

shown. The heat transferring connection over the - -

Heat transfer element 6 can be interrupted by switching off a permanently activated or actuated during normal operation actuator 23. Alternatively, it is also conceivable that the

heat transferring compound by activation or actuation of otherwise not on the

Heat transfer element 6 act

Actuator 23 is interrupted. In the illustrated in Figures 11 and 12

Embodiment, the heat transfer element 6 on serving as a separating element section 12, on which a permanent magnet 24 is arranged. On a permanent magnet 24 opposite side acts a

biased spring means 25 on the portion 12 and tries to move away an open end 26 of the portion 12 of the adjacent heat transfer portion 9 and thereby interrupt the heat transferring connection via the heat transfer element 6. Through a

Magnetic field, which is generated during normal operation with a solenoid device 27, the open end 26 of the portion 12 against a spring force of the spring means 25 to the adjacent

Heat transfer section 9 used and pressed so that during normal operation or during operation of the solenoid device 27, the

ensures heat-transmitting connection and is interrupted after switching off the magnetic field. Since even with a sudden interrupting electrical supply of the solenoid device 27 generates no more magnetic field and the open end 26 of the section is no longer applied to the heat transfer section 9, then the - -

heat transmitting connection automatically interrupted, without a separate activation of the electrically operated actuator 23 is required. The required for the operation of the solenoid device 27 electrical energy is supplied via the housing interface 7 and separate supply lines.

Instead of a magnetic field, which with a

Electromagnet device 27 is generated, the open end 26 of the section 12 can also be displaced by a

Locking element or locking element are retained in a heat-transmitting arrangement or shaping. Once the heat transferring connection is to be interrupted, the locking element or the locking element can be displaced by the electrically operated actuating device 23 and the open end 26 of the section 12 can be released.

In the illustrated in Figures 13 and 14

Embodiment has the electrically operated

Actuator 23 a formed as a ceramic cutting edge 28 separating element, which by the

electrically operated actuator 23 from one of the heat transfer element 6 spaced

Resting position (Figure 13) can be displaced into a heat transfer interrupting heat interrupting position (Figure 14) and the

Heat transfer element 6 severed at the weakening separation point 15. The separating element is used in the

Heat break position also as a thermal insulation and prevents heat transfer across the separator. For this reason, the separating element is in

advantageously made of a material which - -

only very little or not worth mentioning

Has heat conduction properties.

An energy-supplying and possibly also

data transmission line connection of

Data processing unit 3 and optionally the electrically operated actuator 23 can be effected via electrically conductive connection lines 29 which are arranged on or in the heat transfer element 6 and the housing interface 7, a power supply and data transmission to the

Data processing unit 3 back. In an interruption of the heat transfer element 6 then the electrical contact of the

Data processing unit 3 interrupted and thereby prevents, for example, in exceptional

Ambient conditions voltage spikes or faulty digital data are transmitted to the data processing unit.

FIG. 15 shows a side view and in FIG. 16 a sectional view of a heat transfer element 6 on which electrical connection lines 29 are arranged. The electrical connection lines 29 are connected by an electrical insulation layer 30 of the

Heat transfer element 6 separated. Once with the designed as a bimetallic strip 13 separating element the

heat transferring compound via the

Heat transfer element 6 is interrupted, at the same time, the electrical connection lines 29 are interrupted. - -

All variants of the invention described

Data processing module 1 make it possible within a very small working space with the thermal insulation material 5 a very effective thermal insulation for the

To effect data processing unit 3. During normal operation, that of the

Data processing unit 3 generates heat via the

Heat transfer element 6 are discharged, whereas in an excessive increase in temperature, a heat transfer via the heat transfer element 6 is interrupted to the protective effect of the thermal insulation material 5 not to

subverted.

It has been shown that, for example, a

Data processing module 1 according to the invention

Data processing unit 3 may have a solid-state drive in a conventional 3.5-inch housing 2 with standardized dimensions and interfaces. This data processing module 1 can be used in normal operation with conventional data processing equipment and is sufficiently protected in the event of fire by the appropriate thermal insulation material 5 and the interrupted heat transfer element 6. Such an invention

Data processing module 1 can also be used as black box in

Vehicles or aircraft are used. Due to the small dimensions and high data transfer rates that are possible with the data processing module 1 during normal operation, the data processing module 1 according to the invention is also suitable for use as a tachograph and black box in autonomous driving

Vehicles. In addition to an over the thermal insulation material 5 and the interrupted heat transfer element. 6 - -

thermal insulation and thermal insulation can and should the data processing unit 3 expediently also against mechanical stresses and

Be protected against moisture. For this reason, the data processing module 1 can separate protective measures such as a mechanical damping or decoupling of the data processing device 3 relative to the

have surrounding housing 2 or a watertight seal of the housing 2.

It is currently assumed that a

Tachograph with which a complete monitoring and logging of about 24 hours of continuous operation of a vehicle and in particular a partially or fully autonomously operated vehicle is possible to capture and store a data volume of about 5 terabytes. There have been developed solid-state drives that require little space and

also low heat generation during operation have a storage capacity of 6 terabytes or more and in an advantageous manner as

Data processing unit 3 of an inventive

Data processing module 1 and its use as a black box for autonomously driving vehicles. Such a black box with sufficient protection against fire, water and vibration for most possible accidents can be accommodated in a housing 2 which only has the dimensions of a standardized 3.5-inch housing.
