Definitions

• the present invention relates to improvements to thermal complexes, and more particularly to thermal complexes that can be read with their packaging.
• thermal complexes are called products, and in particular mixtures, exhibiting a solidification plateau or a small temperature variation during the entire solidification period, which allows in particular their use as heat transmitters, at their temperature. solidification (or melting), or the narrow range of temperatures corresponding to this solidification.
• solidification level which corresponds to the constant temperature during the melting or solidification of a pure body
• thermal complexes can be used either to store heat which they then transmit (wraps, for example), or to ensure a maintenance of temperature during the transmission of heat from an external source (bain-marie, for example).
• paraffinic complexes since these are, among the thermal complexes, those whose uses are the oldest and most varied. It is known in particular that the melting point of paraffins is in direct relation with their molecular mass, which offers a very wide range of solidification stages, made even more varied by means of the mixtures.
• the present invention therefore relates to prepackaged complexes which are used directly as such in their packaging.
• this packaging is designed to provide temperature control during use, limit unnecessary heat loss, and allow it to be reused.
• thermo complexes characterized in that they consist of at least one elementary volume and packaged in at least one sheet resistant to the temperature of use of said complexes.
• the latter relates to thermal complexes characterized in that they consist of at least one elementary volume and packaged in at least one sheet resistant to the temperature of use of said complexes and reflecting the infrared rays on one side and / or on the other side of the complex.
• cylinders of thermal complexes s 1 are inserted between two sheets s 2 and 3, the sheet s being welded to the peripheral part around the entire periphery of the set of s cylinder. s arranged parallel to each other, and between the cylinders, at 4.
• the sheets enveloping the cylinders can be made of any thermoplastic material that is resistant to temperature. Excellent results have been obtained with polyvinyl chloride sheets.
• the welds between the two sheets can be made thermally or by high frequency, for example.
• s holes 5 are provided, which makes it possible, using a cord, to attach assemblies s, such as those represented in FIG. 1, side a. side or end to end. It is, of course, possible to use all the means of attachment: pressures, staples, sliding closures and the like.
• the user takes a plate, such as that shown in Figure 1; he can dip it directly in hot water to reach the desired temperature, and, when it s ort, he can apply it directly to the place of use, for example on a part of the body, in the case therapeutic use.
• the intermediate weld between two cylinders, indicated at 4 in FIGS. 1 and 2, may not be continuous from end to end until the peripheral weld, which allows certain communications between the chambers containing each of the cylinders; this can make it possible, in particular, to facilitate the elimination of bubbles, if the sheets have been welded under vacuum.
• prisms are used, of general trian ⁇ gular, hemispherical, semi-elliptical or trapezoidal section, which corresponds more precisely for the desired use, notably improving the contact between the subject and the thermal unit. It may also be advantageous, as shown in Figure 3, to add one or more layers 6 of insulating material; this can avoid heat losses, or at least limit them.
• prisms of thermal complexes 10 are inserted between two sheets 12 and 13, the sheets being welded to the peripheral part around the entire periphery of the set of prisms arranged parallel to each other, and between the prisms, at 14.
• the sheets surrounding the prisms can be made of any thermoplastic material resistant to the temperatures of use. Excellent results have been obtained with polyvinyl chloride sheets.
• a metal sheet 16 is fixed, for example, by bonding to the sheet 12.
• this sheet 16 is preferably health reflected, for example on the side of the sheet 12.
• this reflective sheet 16 serves then envelope, and simultaneously it re ⁇ reflects the infrared which is emitted by the complex.
• the sheet 16 can be made reflective on the side opposite to the sheet 12, or even on both sides of this sheet.
• s holes 15 are also provided, making it possible to attach assemblies s such as those shown in FIG. 4, either side by side or end to end.
• assemblies s such as those shown in FIG. 4, either side by side or end to end.
• the implementation of this variant of the invention is carried out in the manner described above, with reference to Figures 1 to 3.
• an additional reflective sheet 19 placed on the side of use. It will be noted, in this regard, that one and / or the other of these health reflective sheets 16 or 19 can be placed outside or inside with respect to sheets 12 and 1.3. It is also possible to provide at least one additional insulating sheet, which is placed on the outside with respect to use (side 12, 16).
• the reflection effect can be obtained by any suitable means, and in particular by metallization of s sheets such as 12 and 13 or of insulating sheets.
• s sheets such as 12 and 13 or of insulating sheets.
• the advantage of such a reflection of infrared radiation is multiple:
• the temperature gradient is flattened, which causes a delay in the solidification of the surface of the complex, and which, in the case of a double reflection ( Figure 5), delays the hardening or crystallization of the thermal complex, on the side of the body to warm up,
• the system then behaving like a mirror which reflects the calories
• the external heat radiation is considerably reduced, which makes it possible to concentrate the transmission of heat on the only conduction, thus making it possible to eliminate in part, and even entirely, the use of conductors such as, for example, metallic charges or metal oxides within the complexes.
• thermometric device for example with liquid crystals, placed in any zone of the assembly and on the outside, during use, making it possible to control the temperature of the thermal complex.
• This characteristic can also be useful when heating the thermal complex, to avoid going beyond the melting stage and reaching dangerous temperatures for the intended use, or even not to risk damaging the materials constituting the complex.
• temperature control is also desirable during use on the subject, in order to avoid holding complexes that have been over-cooled for too long.
• thermal complexes are not arranged in parallel, but according to a curve, a broken or polygonal line, or even according to isolated shelves s one of s s others using a weld bead giving the 'together an aspect of the type "chocolate bar" or similar product.
• the thermal complexes according to the present invention can also be used for wraps in areas where the plates are difficult to use, even by giving them significant curvature. It is then possible to use s tubes which may or may not be linked together.
• the thermal complexes can be extruded in a casing, according to a technique well known in the food industry.
• the strand thus obtained can be continuous or separated with the aid of strings, or it can be cut into closed sections at both ends, for example by a ligature or by a weld. It is thus possible to use the complexes on surfaces which are very uneven or of relatively difficult access, for plates such as those shown in the drawings.
• thermo ⁇ plastic sheets with an optional insulator. It is obvious that these sheets can be complex and have several layers. For example, one can glue one on the other several plastic or metallic layers to form the sheet. Flexibility and the ability to weld thermoplastic materials are thus associated with the mechanical resistance and the thermal properties of the metal.
• sheet 6 ( Figure 3) or 16 ( Figures 4 and 5), which is glued on the planar side to sheet 2 or 12, respectively, allows the application of the opposite face 3 or 13, respectively, on an uneven surface.
• the short side of the trapezoids 8 makes it possible to obtain a curvature of the en ⁇ seems to conform to the shape to be covered, the external face having the sheet 6 or 16 which, in section, follows in a substantially parallel fashion the contour of the surface receiving the application of the complex. It is understood that, depending on the uses, it is possible to have recourse to such and such a sectional configuration, allowing, on the one hand, an optimal thermal transmission, and, on the other hand, a minimum thermal transmission.
• thermotherapy for example the transmission of calories or frigories to the human body, by contact, in particular for thermotherapy or cr otherapy treatments, the complexes according to the invention constituting elements - me ts thermo-diffused.
• the thermal complexes can be divided into elementary volumes and packaged in one or more sheets resistant to the use temperature, preferably arranged so as to present the largest surface on the side of the transmission. thermal, and. on the other side, the best insulation, as much as possible.
