[0033] In one embodiment of the present invention, the means or means are made of a material that differs from the material of the heat transfer body, in particular in the form of a fluid, granulate, mesh, foamed material, powder, fiber, and / or flour or ground material and / or with a sponge structure and / or heat-storing minerals. In particular, the aforementioned means are designed as a composite material, wherein the aforementioned substances are formed in a matrix material such as a resin, preferably in an epoxy resin composite.

[0034] The thermal device can be any device in which heat transfer takes place, for example a heater, a thermos flask, a bathtub, a cold pack, a wine cooler, a radiator, heating pipes, or the like. The thermal device has a heat transfer body. This heat transfer body has a heat transfer fluid chamber and a wall surrounding it. The heat transfer fluid is stored at least temporarily in the heat transfer fluid chamber. Heat transfer takes place via the wall.

On the side facing away from the floor, the pipes are fitted with the insulating thermal material.The invention also includes the technical teaching that, in a concentrate for a thermal device, in particular for a thermal device described here, wherein the concentrate comprises a heat transfer fluid and / or a thermal material described here, the proportion of the base fluid is less than or equal to 50% by weight and the proportion of the additives is correspondingly greater than or equal to 50% by weight, so that the proportions of the base fluid and the additives and / or the thermal material together amount to 100% by weight of the concentrate, with further components not being taken into account. Preferably, the concentrate has a proportion of less than or equal to 1% by weight as the base fluid. In particular, the concentrate is formed with an additive of ethylene glycol - MCT or ethylene glycol - medium-chain triglycerides. The proportion of the additive (ethylene glycol - MTC) is preferably greater than or equal to 99% by weight.The base fluid, which can also be offered separately from the additive in liquid form, is preferably demineralized or distilled water.

[0048] Last but not least, the invention includes the technical teaching that in a method for producing a thermal device, in particular a thermal device described here, the steps are comprised: providing a heat transfer body which has at least one heat transfer fluid space and at least one wall delimiting the heat transfer fluid space, filling the heat transfer fluid space with at least one heat transfer fluid, in particular a heat transfer fluid described here, wherein at least one heat capacity-changing and / or conductivity-changing agent is provided on the inside and / or outside of the heat transfer body, selected from the group comprising: a coating, ribs, recesses, moldings, deflections, fans, insulation, sponges, porous minerals and / or a thermal material described here or the like.

[0049] In one embodiment, the agents are applied to the wall by casting. In another embodiment, the agents are applied by casting a matrix material in which at least one additive, preferably several additives, are embedded, in particular by casting an epoxy resin in which the additives firebrick, volcanic stone, talc, coconut shell, graphite, and / or copper are embedded, preferably in powder form, onto the wall and hardening of the agents, in particular the matrix material.

[0050] The thermal device can be any desired thermal device. The thermal device is preferably a radiator, preferably a radiator with a wall made of metal or a metal compound. The wall surrounds and / or delimits the heat transfer fluid chamber, which is designed to accommodate the heat transfer fluid. Thus, the wall essentially forms the heat transfer body. The heat capacity-modifying and / or conductivity-modifying means are arranged inside and / or outside the heat transfer body, in particular the wall. The means can be arranged detachably or permanently. Preferably, the means are arranged permanently, in particular essentially by means of a material bond. For example, the means can be applied by painting, varnishing, spraying, immersion bathing, gluing, casting, welding, soldering, and the like. A preferred embodiment provides for the means to be applied to the wall by casting.For this purpose, the agents are preferably designed as a curable matrix material into which additives are embedded. The matrix material is preferably a casting resin, in particular an epoxy resin, which can be cured. First, the agents are produced. For this purpose, a flowable material is produced which comprises the matrix material and the additive(s). The mixing ratio of matrix material and additives can be adjusted depending on the application and preferably corresponds to a mixing ratio described here. The additives are added to the liquid matrix material, preferably the liquid epoxy resin, while stirring. The additives are preferably in powder form. The proportion of additives in relation to the matrix material is less than 15% by weight, preferably less than 10% by weight, and most preferably less than 7.5% by weight.The proportions of the additives are preferably at least partially different, so that, for example, 10% of the additives is copper and more or less than 10% of the additives is another additive, for example volcanic stone. After the agent has been mixed, it is applied to the wall. For this purpose, aids such as a frame, depressions, moldings and the like can be provided on the wall. In particular, the aids can be removed from the wall later, provided they do not involve direct deformations of the wall. For example, a pouring frame is provided which, together with the wall, forms a pouring chamber. The liquid agent is poured into the pouring chamber and hardens. After hardening, the pouring frame is removed. The hardened agent is firmly bonded to the wall.

[0051] The thermal material, which sits on the wall - detachably or permanently - has a volume. The volume is designed such that sufficient heat storage and heat radiation can be achieved. In particular, the thermal material has a material thickness or strength greater than 2.5 mm, preferably greater than 5 mm, and most preferably greater than 7.5 mm. Color mixtures can also be incorporated into the liquid material to make the thermal material visually appealing. The thermal material can also be formed separately as a plate, which is subsequently attached to the wall. The plate or thermal material preferably has a wall thickness or strength no greater than 5 cm, preferably no greater than 4 cm, and most preferably no greater than 3 cm. The shape of the thermal material is preferably selected such that one side of the wall is covered.In one embodiment, the thermal material is preferably designed as a thermal conduction and / or thermal radiation material. In another embodiment, the thermal material is designed as a thermal insulator material. The thermal insulator material is preferably applied to the wall by casting, similar to the thermal radiation material. A thermally insulating material such as foam glass, foamed glass, or the like is incorporated into the matrix material. The thermally insulating material is preferably also in powder form or in small pieces and is embedded in the liquid matrix material, then applied to the wall, where it hardens. The method preferably provides for one side or location of the wall to be cast with a thermally insulating material, and another side or location to be cast with a thermally conduction thermal material. Other combinations are also conceivable within the scope of the disclosure.In one embodiment, the thermal conduction material and the thermal insulation material may differ not only in material but also in material thickness. For example, the thickness of the insulating material may be greater than that of the thermal radiation material.
