Definitions
- the present invention relates to the use of a composite material for heat management in the electrical and / or electronic field, in particular in the automobile, comprising a lattice-like structure filled with phase change material (PCM) and a composite consisting of a lattice structure provided with PCM is filled and this filled grid structure is on a cover layer or between two cover layers.
- PCM phase change material
- PCMs latent heat storage materials
- PCMs can both store and release heat in the form of latent heat.
- PCMs undergo a phase transition when heat is applied or released. This can be, for example, a transition from the solid to the liquid phase or vice versa.
- the phase transition point is reached, the temperature remains constant until the material is completely converted.
- the heat supplied or removed during the phase transition which does not cause a temperature change in the material, is called latent heat.
- phase change materials examples include paraffins, waxes, sugar alcohols, alcohols, sugars, polymers, in particular thermoplastic polymers, water, organic acids, such as fatty acids, aqueous salt solutions, such as salt hydrates, or amides (WO2008087032A1, US8580171 B2).
- the elastomeric matrix also has a low thermal conductivity; furthermore, these materials can not be used to build up dimensionally stable components since the entire complex softens when the composite melts.
- the known PCM / graphite composite materials have the disadvantage that a relatively high (at least> 10% by weight) binder content must be used, since otherwise the integrity of the composite material is not given. With a high binder content, conductive additive mixtures of at least 20% by weight must be added, which reduces the storage capacity proportionally but by at least 25%.
- the object of the invention is therefore to provide a composite material, which can be used for thermal management, with which the above-mentioned disadvantages of the prior art are overcome.
- the object is achieved by the use of a composite material for heat management in the electrical and / or electronic field, such as in the automobile in the temperature range up to 600 ° C, preferably up to 150 ° C, comprising a grid structure filled with phase change material (PCM) is solved.
- a composite material for heat management in the electrical and / or electronic field such as in the automobile in the temperature range up to 600 ° C, preferably up to 150 ° C, comprising a grid structure filled with phase change material (PCM) is solved.
- PCM phase change material
- the dimensional changes in all spatial directions, due to the PCM can be reduced to less than 5%, in particular 3%, and thus composite materials can be manufactured with low skill tolerances.
- the heat capacity is less affected by the lattice structure, in contrast to the use of Leitadditiven, with less than 15% and the heat conductivity even due to directed heat flows due to continuous areas of high thermal conductivity, compared to the pure PCM improved by more than 300%.
- a lattice structure As a lattice structure is understood in the context of the present invention, a kind of hole structure consisting of threads, ropes, wires, sheets or the like, which are interconnected so that between the individual nodes / intersections always a gap remains.
- the dimensions such as height, width, depth and shape of the structure is not limited. As forms come polygons, in particular squares, hexagons (such as honeycombs) or circles in question.
- the dimensions of the squares will be determined by the measurement of the length and width and advantageously each have a size of 1 to 40 mm, preferably 2 to 40 mm, particularly preferably 3 to 30 mm.
- the dimensions of the circles are determined by measuring the diameter and would advantageously have a size of 1 to 40 mm, preferably 2 to 40 mm, particularly preferably 3 to 30 mm.
- the dimensions of the honeycombs are determined according to DIN 29970 (1998-09) and advantageously has a size of 1 to 40 mm, preferably 2 to 40 mm, particularly preferably 3 to 30 mm.
- the lattice structure of metal, ceramic, graphite or any mixtures thereof may consist of a mixture of metal and ceramic, metal and graphite, ceramic and graphite or a mixture of metal, ceramic and graphite.
- the grid structure is metal, it is preferably selected from the group consisting of aluminum, copper or steel. Particularly preferably, the lattice structure consists of aluminum.
- the lattice structure is made of ceramic, it is preferably selected from the group consisting of aluminum nitride, aluminum oxide, silicon carbide or carbon fiber reinforced silicon carbide (C / SiC). Particularly preferably, the lattice structure consists of C / SiC.
- the lattice structure is graphite, the graphite is preferably selected from the group consisting of natural graphite, synthetic graphite or expanded graphite. Particularly preferably, the lattice structure consists of expanded graphite.
- graphite such as natural graphite is usually mixed with an intercalate such as nitric acid or sulfuric acid and heat-treated at an elevated temperature of, for example, 600 ° C to 1200 ° C. (DE10003927A1)
- Expanded graphite represents a graphite which, in comparison to natural graphite in the plane perpendicular to the hexagonal carbon layers, for example around the Factor 80 or more is expanded. Due to the expansion, expanded graphite is characterized by excellent formability and good intermeshability. Expanded graphite may be used in sheet form, preferably using a film having a density of 1.3 to 1.8 g / cm 3 . A film having this density range has thermal conductivities of 300 W / (mK) to 500 W / (mK). The thermal conductivity is determined by the Angstrom method ("Angström's Method of Measuring
- the grid structure has a wall thickness of 0.01 to 2 mm, preferably 0.03 to 0.5 mm, particularly preferably 0.05 to 0.2 mm, since thereby the heat generated by operation of the electrical and / or electronic component can be derived faster and the influence on the heat capacity is still low.
- a horizontal thickness of the lattice structure of 0.5 to 50 mm, preferably 1 to 30 mm, particularly preferably 2 to 20 mm.
- the dimensioning of the thickness allows tailor-made thermal management for various electronic and / or electrical components.
- Electronic components are, for example, laptops, smartphones, LCDs (liquid crystal screens), LEDs (light-emitting diode screens), OLEDs, (organic light-emitting diode screens), etc.
- Electrical components are, for example, power modules, printed circuit boards or the like.
- the composite is divided into many small areas, each self-contained. This significantly reduces the leakage of large amounts of PCM in the event of damage.
- the strength of the composite by more than 200% and the modulus of elasticity increased by more than 400%, while the amount of binder can be reduced to a maximum of 2 wt.% At the same time.
- Another advantage of the lattice structure is that, in addition to can be omitted and thus the heat capacity only slightly, but not more than 15%, is lowered.
- the thermal conductivity and thus the transmittable heat flow can be adjusted specifically. It is also possible to use unbalanced lattice structures. This allows the provision of a custom PCM material for the component.
- Particularly suitable PCMs are sugar alcohols, paraffins, waxes, salt hydrates, fatty acids, preferably paraffins, salt hydrates and waxes.
- sugar alcohols there may be used, for example, pentaerythritol, trimethylolethane, erythritol, mannitol, neopentyl glycol and any mixture thereof.
- paraffins saturated hydrocarbons having the general empirical formula C n H 2n + 2 may be used, where the number n may be between 18 and 32. The molar mass of such paraffins is thus between 275 and 600 grams per mole.
- the salt hydrates used can be, for example, calcium chloride hexahydrate, magnesium chloride hexahydrate, lithium nitrate trihydrate and sodium acetate trihydrate.
- capric, lauric, myristic, palmitic, stearic and any mixture thereof may be used as fatty acids.
- the salt hydrates can be used, for example, calcium chloride hexahydrate, magnesium chloride hexahydrate, lithium nitrate trihydrate and sodium acetate trihydrate.
- the choice of PCM depends on the temperature range of the application.
- the preferred use of the composite in the electrical and / or electronic field of the automobile is in the temperature range up to 600 ° C, preferably using salt hydrates.
- temperature range rich to 150 ° C paraffins and waxes are preferably used.
- the preferred operating temperature range is up to 100 ° C, with paraffins and waxes preferably being used.
- the PCM may be in free, bound, encapsulated or microencapsulated form.
- Suitable encapsulating materials are plastics such as polymethyl methacrylate.
- the encapsulating material forms a plastic sleeve for the PCM.
- microencapsulated is meant an encapsulation of ⁇ 5 mm.
- the PCM in the form of microencapsulated particles has an average particle size of ⁇ 5 mm, preferably 3 to 100 ⁇ m, particularly preferably 3 to 15 ⁇ m. If the particle sizes exceed 5 mm, there is a significant drop in the heat input into the capsule itself and the PCM inside the capsule only melts very slowly. This means that often the entire heat capacity can not be used. If the capsule is too small results in an unfavorable ratio of PCM and non-active capsule shell, which in turn adversely affects the heat capacity.
- a binder is added to the PCM, i. the grid structure is filled with PCM and binder.
- the binder may be selected from the group consisting of epoxy resins (such as Araldite 2000 (2014)), silicone resins or acrylate resins.
- the binder content is 2 to 40% by weight, preferably 5 to 30% by weight, more preferably 5 to 10% by weight. Due to the low binder content, the strength of the composite material can be compared increase the unbound by more than 100% and the heat capacity is only slightly affected. In the most preferred case, the heat capacity is reduced by only 10%.
- a conductive additive is added to the PCM or the PCM and binder. This additionally increases the thermal conductivity. Depending on the conductive additive quantity, the thermal conductivities can be increased up to 20 W / (m-K).
- this conductive additive is selected from the group consisting of synthetic graphite, expanded graphite, boron nitride, aluminum or copper. Expanded graphite is particularly preferably used as a conductive additive.
- the proportion of the Leitadditives 0 to 90 wt.%, Preferably 5 to 30 wt.%, Particularly preferably 10 to 20 wt.%.
- the addition of a conductive additive increases the thermal conductivity in addition to the lattice structure and allows the transmission of larger heat fluxes. With a low admixture of up to 10% by weight, the influence on the heat capacity is still within an acceptable range of less than 10%.
- the mixing ratios of PCM, binder and conductive additive can be adjusted as required, the minimum proportion of the binder being 2% by weight and the minimum amount of PCM being 60% by weight. There is no minimum percentage for the lead additive. In sum, these components always give 100 wt.%.
- Another object of the present invention is a composite material comprising a grid structure filled with PCM, wherein the filled grid structure is on a cover layer or between two cover layers. Also for this composite material, the embodiments as described above for the lattice structure, the PCMs, the binders and the conductive additives can be used.
- the cover layers of this composite material according to the invention can be selected from the group consisting of graphite foils, carbon fiber fabric, carbon fiber fabric, copper foil or aluminum foil, the graphite foils being preferably used.
- the cover layers have a thickness of 10 ⁇ m to 3 mm, preferably from 0.2 to 2 mm, particularly preferably from 0.5 to 1 mm.
- the cover layers of graphite foils consist of expanded graphite with a density of 1.3 to 1.8 g / cm 3 .
- Figure 1 shows a schematic plan view of the PCM / lattice composite material according to the second embodiment of the present invention with broken surface, illustrating the internal, filled grid structure.
- Figure 2 shows a schematic side view according to the second
- FIG. 1 shows a schematic plan view of the second exemplary embodiment.

- On the bottom and top of each graphite foil is attached as a cover layer (3).
- Fig. 2 shows a schematic side view of the sample body of Figure 1 according to the second embodiment of the present invention.
- the thickness (h) of the sample basket is 1 1 mm. It can be clearly seen that the lattice structure (2) filled with PCM (1) is enclosed on both the upper side and the lower side by the cover layers (3).
- a test specimen with the dimensions 140 x 95 x 1 1 mm is produced.
- a honeycomb structure made of 50 layers of aluminum foil with a thickness of 50 ⁇ by staggered selective connecting with a total of 2 g of adhesive (Araldit 2000 (2014)) and then pulled apart produced.
- the desired honeycomb height is cut to length from the resulting block.
- This structure is then filled with 120 g of PCM binder material (100 g Micronal, m.p. 28 ° C and 20 g Araldit 2000 (2014).
- a test specimen with the dimensions 140 x 95 x 1 1 mm is produced.
- This structure is then filled with 120 g of PCM binder material (100 g Micronal, melting point 28 ° C and 20 g Araldit 2000 (2014) and clamped between two layers of graphite foil (500 ⁇ thickness and 1, 8 g / cm 3 density).
- the thermal conductivity perpendicular to the sample plane is 1.5 W / (mK), clearly above the pure PCM sample (reference sample: composition as in Example 1, but without aluminum honeycomb structure) with 0.3 W / (mK) is (see Table 1). If, according to the prior art, conductive additives were admixed, at least 30% by weight would be necessary to achieve the same thermal conductivity as the heat capacity of the But reduce the sample by at least 30%. By using the aluminum honeycomb, however, this is only reduced by 15%.
