Description
- This nonprovisional application claims priority under 35 U.S.C. §119(a) to German Patent Application No. 10 2013 211 505.9, which was filed in Germany on Jun. 19, 2013, and which is herein incorporated by reference.
- 1. Field of the Invention
- The invention relates to a temperature control device for the temperature control of a component, whereby the component is in particular an electrical and/or an electronic component, having a tube and a housing element, whereby a first fluid can flow through the tube and a second fluid can flow around the temperature control device.
- 2. Description of the Background Art
- In order to cool or heat as necessary electrical and electronic components, which are being used increasingly in motor vehicles, devices must be provided that permit this. In order to keep the energy consumption of the systems as low as possible, it is necessary to realize a best possible thermal connection of the components to be cooled and heated.
- At the same time, however, there is the requirement to install the components to be cooled or heated electrically insulated and to connect them to a temperature control device, in order to avoid short circuits and functional interferences.
- Thermoelectrically active materials can be used to supply heat to such a component or to remove heat from it. These include, for example, Peltier elements. These can transport a defined amount of heat either by an applied voltage or by generating a voltage based on a temperature gradient predominating at the interfaces of the Peltier element. Peltier elements can be connected advantageously to a fluid circuit with one of its interfaces. An actively temperature-controllable medium can flow through the fluid circuit. Heat transport from or to the component to be cooled or heated from or to the fluid of the fluid circuit can then be generated via the Peltier elements.
- A particular disadvantage in regard to the solutions in the prior art is that the thermal resistance between the thermoelectrically active materials, such as, for example, the Peltier elements, and the heat source or heat sink is not optimally designed. The connection of the thermoelectrically active materials is also often complex and laborious. In addition, the measures taken against the occurrence or the effect of thermomechanical stress are often not optimal.
- It is therefore an object of the present invention to provide a temperature control device which is optimized compared with the solutions in the prior art. In particular, a better connection of the component to be heated or cooled to a heat source or a heat sink is to be achieved, as well as an increase in the resistance to thermomechanical stress.
- An exemplary embodiment of the invention relates to a temperature control device for the temperature control of a component, whereby the component can be an electrical and/or an electronic component, having a tube and a housing element, whereby the first fluid can flow through the tube and a second fluid can flow around the temperature control device, whereby the housing element is formed by a cup-like cover, which is connected to the tube and forms a receiving area for the component, in which the component is taken up.
- The design is especially advantageous, because an effective temperature control unit can be produced by simply designed and easily producible elements. A temperature control unit in this case can be used both for supplying heat to a component and also for removing heat away from a component. The direction of the heat transport in this case can be influenced, inter alia, by the temperature level of the fluid and the heat generation at the components to be temperature controlled.
- The component can be formed by a thermoelectric module, whereby the thermoelectric module has a module housing having at least two opposite first walls, whereby a plurality of thermoelectric elements is arranged between the first walls of the module housing, whereby the thermoelectric elements have opposite surfaces, which in each case are in thermal contact with one of the first walls of the module housing of the thermoelectric module, whereby the thermoelectric elements are at least partially electrically connected to one another via conductive bridges.
- A thermoelectric module is characterized by the use of thermoelectrically active materials. These have the property of either generating a voltage based on an applied temperature gradient or of generating a temperature gradient by application of a voltage due to the heat transport. The thermoelectric module in this case is formed advantageously as a closed physical unit, whereby the thermoelectrically active materials are enclosed in a module housing.
- It is also advantageous, if the housing element has a first recess, whereby the recess is arranged on a surface of the temperature control device, the surface over which the second fluid flows.
- Further, the tube can have a second recess, whereby the second recess is arranged on a tube surface over which the first fluid flows.
- The thermal connection of the fluid to the component to be temperature controlled can be improved by the recesses. The resistance opposing the heat transfer is reduced thereby, as a result of which the overall efficiency of the device can be increased.
- An exemplary embodiment can have the component connected fluid-tight to the housing element at the edge region of the first recess and/or the housing element can be connected fluid-tight to the tube.
- Unwanted contact between the fluid and components that are not electrically insulated can be avoided by a fluid-tight connection. Areas with no flow can be produced within the temperature control device by a fluid-tight connection.
- The component can have surface-increasing elements, whereby the surface-increasing elements are arranged on a surface over which the first fluid flows and/or are arranged on a surface over which the second fluid flows.
- Surface-increasing elements such as, for example, fins can contribute overall to an improved heat transfer, as a result of which the efficiency of the temperature control device can be increased.
- Also, at least one thermal decoupling element, which restricts the fluid flow of the first fluid to a section of the tube, can be provided in the tube.
- The flow of the fluid within the tube can be influenced by a thermal decoupling element. Regions with no or little flow can be produced, which can serve as a thermal buffer, for example.
- In an embodiment of the invention, it can be provided that the housing element and/or the tube have an electrically insulating layer on at least one surface facing the component.
- Electrically insulating layers can be produced, for example, by ceramic substances, which are applied to the surfaces to be insulated. Short circuits and therefore damage to the temperature control device can be prevented by electrical insulations.
- The module housing can have second walls, which close the module housing fluid-tight with both first walls.
- In this way, the interior of a module housing, particularly the thermoelectric modules and conductive bridges, can be protected from the effects of the fluid. This is helpful in avoiding short circuits.
- At least one of the second walls can be formed by a ceramic wall element or a metallic wall element.
- A fluid-tight sealing of the module housing can be achieved by such wall elements. Ceramic wall elements offer the advantage that in addition an electrical insulation is achieved through their use.
- The second walls can be connected fluid-tight to the first walls and/or are connected fluid-tight to the housing element and/or are connected fluid-tight to the tube.
- This is especially advantageous in order to prevent the formation of short circuits and damage to the temperature control device.
- The first walls can be coated in an electrically insulating manner on one or both sides.
- In an embodiment the first walls can be formed by the housing element and the second of the first walls is formed by the tube or in that one of the first walls is formed by the housing element and the second first wall by a plate-like element.
- Depending on the design of the tube and the housing element, different configurations of the module housing can be realized. When no recesses are provided in the housing element and the tubes, an especially simple structure of the module housing can be achieved. A more cost-effective structure can be achieved overall by minimizing the necessary number of parts.
- In an embodiment, the tube can be formed by a flat tube with two opposite broad sides, which are connected together by two opposite narrow sides, whereby each of the broad sides is connected fluid-tight to a housing element in each case and a receiving area for a component is formed between a broad side and a housing element, into which a component is inserted.
- The provision of elements to be temperature controlled on both sides of the flat tube is especially advantageous, since this allows for an optimized heat transfer. In addition, this type of arrangement is especially advantageous, as there are no boundary surfaces around which the first fluid flows, on the one hand, and the second fluid flows, on the other. In terms of energy this would not be efficient, as the heat transport would only occur via these boundary surfaces and the maximum possible heat performance or cooling performance at the element to be temperature controlled could not be achieved.

However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

FIG. 1 shows a perspective view of a temperature control device 1. Temperature control device 1 is substantially formed by ahousing element 2, which is placed on atube 3.FIG. 1 shows a temperature control device 1, which has ahousing element 2 both on the top side and on the bottom side oftube 3. The following description is limited to the embodiment of the top area of temperature control device 1, the bottom area being made mirror symmetric to the top area. -
Housing element 2 is formed cup-like and at its bottom end has aflange area 10, which is formed circumferential around the cup-like body ofhousing element 2.Flange area 10 serves as a connecting surface totube 3. - A receiving area, in which a component 4 is inserted, is formed between
tube 3 andhousing element 2. Component 4 can be a thermoelectric module or another electrical or electronic component, for example. - Component 4 on a
first wall 30 has two openings 5, through which electrical contacting of component 4 can occur. A connecting layer 7 is provided betweenfirst wall 30 and an inner surface ofhousing element 2. Said connecting layer 7 serves as the fluid-tight connection of component 4 tohousing element 2. Advantageously, connecting layer 7 is formed by a silicone adhesive. The silicone adhesive offers the advantage that it can also absorb the mechanical disturbances and thermomechanical stress, thereby assuring a secure connection between component 4 andhousing element 2. -
Housing element 2 has arecess 6, which is arranged in the shape of a rectangle in the upward facing area ofhousing element 2.Recess 6 is covered completely byfirst wall 30 of component 4. - A
first fluid 8 can flow throughtube 3. Asecond fluid 9 can flow around temperature control device 1 as a whole. -
FIG. 2 shows a section through temperature control device 1, which is already illustrated inFIG. 1 . - The inner structure of component 4 can be seen in particular in
FIG. 2 . A plurality of thermoelectricallyactive materials 20 is arranged in the interior of component 4. These are formed in the shape of rectangles and arranged in rows parallel to one another. In each case, two adjacent thermoelectricallyactive materials 20 are connected to one another in an electrically conductive manner via aconductive bridge 21. In this way, the thermoelectricallyactive materials 20 arranged within component 4 are connected electrically in series to one another. - The thermoelectrically
active materials 20 are connected viaconductive bridges 21 to the oppositefirst walls 30 of component 4. Viaconductive bridges 21 andfirst walls 30, a thermal exchange between the thermoelectricallyactive materials 20 and, for example,fluid 9 can occur outside temperature control device 1 orfluid 8 in the interior oftube 3. - It can be seen further in the section of
FIG. 2 that connecting layer 7 is provided betweenfirst wall 30 andhousing element 2. It runs completely aroundrecess 6 and represents a fluid-tight connection between component 4 andhousing element 2. - The bottom
first wall 30 is also connected to an outer surface oftube 3. In an advantageous embodiment the connection can also be realized by a silicone adhesive, as a result of which a fluid-tight connection forms betweentube 3 and the bottomfirst wall 30. A fluid-tight adhesion betweentube 3 and the bottomfirst wall 30 is not absolutely necessary, however. - A hollow space filled with air, for example, and used for thermal insulation toward the outside, can form between the outer thermoelectrically
active materials 20 and the inner surface ofhousing element 2. - A separation of
first fluid 8, which flows throughtube 3, andsecond fluid 9, which flows around the temperature control device 1 as a whole, results due to the fluid-tight connection betweenflange area 10 and outer surface oftube 3. - A plurality of
fin elements 22 is shown intube 3 ofFIG. 2 . These are cut out of abaseplate 23 and bent at a 90° angle.Baseplate 23 is arranged within arecess 26 oftube 3 at thefirst walls 30 of component 4. A connecting layer can be provided in each case betweenbaseplate 23 andfirst wall 30. - In the illustration of
FIG. 2 , abaseplate 23 withfin elements 22 is arranged both on bottom component 4 and on top component 4. These are formed identical and arranged rotated to one another by 180° on the particular component 4. - Each of the
baseplates 23 is angled at one of its end regions such that a thermal decoupling element is formed, which separates thermally a middle region oftube 3 from an edge region. In the exemplary embodiment ofFIG. 2 , this is achieved by bending ofbaseplate 23. A wall is produced as a result, which separates the central region oftube 3 from thelateral flow regions 25. The separation bythermal decoupling element 24 can be made fluid-tight but need not necessarily be fluid-tight. The thermally separatedregions 25 are advantageously filled with air and thus form a thermal insulation toward the outside. - The
first walls 30 can be advantageously made of a material such as silicon nitride or aluminum oxide or aluminum oxide/zirconium oxide or an aluminum nitride material or an alloy of the aforementioned materials.Housing element 2 can be advantageously made of an austenitic or ferritic stainless steel or of aluminum or of a plastic material.Tube 3 is also advantageously made of an austenitic or ferritic stainless steel or an aluminum material or a plastic material. -
Fluid 8, which flows throughtube 3, is advantageously the fluid with the higher temperature level. Accordingly,fluid 9, which has a lower temperature level in comparison tofluid 8, flows overall around temperature control device 1. This is particularly advantageous because connecting layer 7, which advantageously is a silicone adhesive, is thus not exposed to unnecessarily high temperatures. - The connection between
housing element 2 andtube 3 in the area offlange 10 is advantageously made by laser welding.Fin elements 22 orbaseplate 23 is advantageously connected by brazing or active metal brazing tofirst walls 30.Fin elements 22 orbaseplate 23 andthermal decoupling element 24 is formed of stainless steel. Alternatively, other metallic materials can also be provided or a base material can be coated with a metallic coating. -
Fin elements 22 ofFIG. 2 are only exemplary. In alternative embodiments, for example, a corrugated fin element can also be placed intube 3 or fastened in it. - In order to be able to create a permanent connection between
fin elements 22 orbaseplate 23 andfirst wall 30, it may also be necessary to coat or metallizefirst wall 30 on the side facingfin elements 22. To this end, it can be provided, for example, to apply a copper layer or a nickel layer or a copper-silver layer or a silver layer. Preferably nickel or alloys of silver and copper or titanium-based solder can be used for connection betweenfirst wall 30 andfins 22 orbaseplate 23. -

Athermal decoupling element 24 is formed on the right lateral edge region of the fin element by bending a section upwards by 90°. This is used to separate the inner region oftube 3 in a flown-through region alongfin elements 22 and an adjacent thermally separatedregion 25. - The fin element of
FIG. 4 is an exemplary illustration. Designs different herefrom can also be provided in alternative embodiments. -

Connectinglayer 45, which is, for example, a brazing foil or a brazing paste, follows thereafter in the upward direction. Acoating 46, which is applied toconductive bridges 21, follows on connectinglayer 45.Coating 46 can be made, for example, of nickel or of silver or of gold or of a molybdenum-silver coating or a gold or silver mixture coating. A connectinglayer 47, which is used for connecting the thermoelectricallyactive materials 20 toconductive bridges 21, follows oncoating 46. - The thermoelectrically
active materials 20, for example, can include a material such as cobalt-antimony or bismuth-antimony or bismuth-telluride or zinc-antimony or magnesium silicon or manganese silicon or of a silicon-based material. Combinations of the individual materials with one another are also possible. - The connection of thermoelectrically
active materials 20 toconductive bridges 21 occurs, for example, via a welding or brazing or a sintering pressure process.

As a departure fromtemperature control device 40, tube 3 a now also no longer has a recess. Thermoelectricallyactive materials 20 orconductive bridges 21 can accordingly also be connected to tube 3 a without a downward directedfirst wall 30. - In the exemplary embodiment of
FIG. 8 , thermoelectricallyactive materials 20 orconductive bridges 21 without supplementary walls are connected directly totop housing element 41 or to tube 3 a.
