    [0004] Stabilized thermal collector.
    [0005]
    [0006] FIELD OF THE INVENTION
    [0007] The present invention relates to a stabilized thermal collector in solar thermal applications and installations. The stabilized thermal collector has been conceived and realized to obtain numerous and notable advantages over other existing means of analogous purposes.
    [0008]
    [0009] STATE OF THE PREVIOUS TECHNIQUE
    [0010] Several types of thermal collectors are known for solar thermal installations according to specific purposes, such as continuous generation or cogeneration.
    [0011]
    [0012] In this sense, thermal collectors can be mentioned with a core of melting salts that provide a good way to store solar energy and maintain its transformation overnight.
    [0013]
    [0014] Although these thermal collectors are used as a solution to situations of economic optimization in energy production in large plants, their costs make it unfeasible for any other application. Not to mention, that even despite their cost, these thermal collectors only work in specific thermal and power ranges outside of which not only loses efficiency but also becomes inoperative.
    [0015]
    [0016] Likewise, other thermal collectors based on borosilicate glass vacuum tubes, consisting of two concentric cylinders separated by a vacuum chamber, are known. The use of energy occurs through a fluid that is heated as it travels inside the central cylinder.
    [0017]
    [0018] However, these thermal collectors still do not solve the problem of limiting their temperature ranges since the liquids when heated above the evaporation point as well as the gases increase the pressure inside the cylinder central glass, limiting the temperature to ranges. Not to mention the limitations in its possible applications and its scalability
    [0019]
    [0020] DESCRIPTION OF THE INVENTION
    [0021]
    [0022] The stabilized thermal collector of the invention presents a new strategy when designing thermal collectors: instead of using a conductive energy core in a fluid way that can be exploited, elements oriented to heat collection will be used, performing the rest of the functions such as exploitation dependent on the function and not on the collection.
    [0023]
    [0024] The stabilized thermal collector is intended to collect thermal energy from the sun while remaining stable mechanically and thermally. For this, the stabilized thermal collector has 5 distinct parts that fit together forming a single object that is capable of collecting radiation from the sun while remaining stable mechanically and thermally. These parts are the conductive filament, the stabilizing core, the glass capsule, the plug and the thermal outlet. The conductive filament is formed by a thermo conductive element. And it is characterized by a constant of high thermal conductivity as well as a high melting point, and a broad and practically continuous absorption spectrum.
    [0025] The stabilizing core is formed by a thermo stable element. It is characterized by a constant of medium thermal conductivity, a high melting point, and a broad and practically continuous absorption spectrum.
    [0026] The glass capsule is formed by a transparent element. It is characterized by a virtually non-existent absorption spectrum in the solar spectrum.
    [0027] The plug is formed insulating and structural elements. It is characterized by low thermal conductivity,
    [0028] The thermal output is formed thermal and structural conductive elements. It is characterized by a high thermal conductivity, a mechanical resistance, as well as a large surface.
    [0029]
    [0030] The stabilized thermal collector is designed to collect solar radiation through the conductive filament and the stabilizing core, from the outside through the glass capsule and the containing chamber that it contains. And transport it in the form of heat through the conductive filament to the thermal outlet, where it will blur through its large surface, which in turn will fix the filament. The cap closes the glass capsule creating the container chamber that isolates the conductive filament and the stabilizer core, allowing to create an adsorption of low pressure inert gas.
    [0031]
    [0032] The conductive filament is constituted of a thermoconductive element such as tungsten, whereby the position of the conductive filament is in the inner part of the glass capsule formed of a transparent element such as quartz. Just around the conductive filament and delimited by the glass capsule is the container chamber whose atmosphere is composed of inert gases at low pressure such as krypton and contained by the cap made of insulating elements such as silicone and structural elements such as borosilicate glass, which sits on the thermal outlet formed thermal and structural conductive elements such as Aluminum or Copper. The conductive filament is supported by the thermal output and supports the stabilizing core composed of a thermo stable element such as carbon.
    [0033]
    [0034] The thermal collector collects almost all the solar radiation through the conductive filament and the stabilizing core, as both have a broad and practically continuous absorption spectrum, from the outside through the glass capsule with an almost non-existent absorption spectrum in the spectrum solar and the container chamber that it also contains transparent to the solar spectrum. All that solar radiation absorbed by the conducting filament and the stabilizing core is transformed into heat that is transmitted by the conducting filament while the stabilizing core will vary in temperature more slowly by stabilizing the temperature of the conducting filament. The conductive filament transports the heat to the thermal outlet, where it will diffuse through its large surface area, reducing the temperature, in addition to its larger size and mass, will fix the filament stabilizing it with respect to the rest of the pieces. The cap closes the glass capsule by means of the insulating element that is supported by the structural element creating the container chamber that insulates the conductive filament and the stabilizing core avoiding energy losses by convection, allowing to create an atmosphere of low pressure inert gas that avoids chemical innervations and stabilize the conductive filament and the stabilizing core.
    [0035] BRIEF DESCRIPTION OF THE DRAWING
    [0036] In order to complete the description that will then be carried out, and in order to help a better understanding of the characteristics of the invention, the present descriptive report of a plan is attached, based on whose figure innovations and innovations will be more easily understood. advantages of the device object of the invention.
    [0037]
    [0038] Figure 1 represents the complete diagram of the stabilized thermal collector, where we can distinguish the conductive filament (1), the stabilizing core (2), the glass capsule (3), the cap (4) container chamber (5) and the outlet thermal (6).
    [0039]
    [0040] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0041] At present there are very different materials with which to make the various parts of the stabilized thermal collector, and multiple techniques that could be used in the preparation of the conductive filament and the stabilizing core. However, for simple economy, generalized materials and techniques have been chosen, which resist the thermal conditions to which the collector is subjected. Thus, the conductive filament is a tungsten metal cylinder obtained by compression and winding, the stabilizing core is pyrolytic graphite, the cap is silicone but reinforced with borosilicate glass, the glass capsule is made of molten quartz, the thermal output is Aluminum and the container chamber is filled with Krypton gas.
    [0042]
    [0043] Consequently, to achieve a stabilized thermal collector capable of providing all the energy required by a family capturing it from the sun, we will start from a parabolic mirror of one meter of radius, which will concentrate 6000 w / h on average for 12 hours, in the focus of the parabola, where the stabilized thermal collector is located. The stabilized thermal collector part of a mold where the pyrolytic carbon is deposited which we surround with a tungsten filament from the lighting industry, we will introduce it into a hollow cylinder of molten quartz with low absorbance in the infrared of the used in buckets of spectroscopy with a perimeter of 2 dm and a thickness of 1 mm and 6 dm in length in what constitutes the glass capsule. We will place the thermal outlet at the lower end of the glass capsule and manufactured from a machined aluminum cylinder die cutting channels that facilitate thermal flow to the different applications in which it requires energy through convection of fluids, while those that require energy by conduction will obtain it by direct contact of an aluminum foil that allows to increase and decrease the contact between them. At the junction between the thermal outlet and the glass capsule we will deposit borosilicate glass in both pieces and we will join them with silicone, creating the cap. We will reproduce this same structure in the opposite position of the glass capsule. Before sealing the glass capsule, we fill the container chamber with Krypton gas and lower the chamber pressure to 0.7 Atmospheres. The air passing through one of the perforations will be heated and allows applications such as air cooking, air compression or Stirling generators and motors, floor heating. The water when passing through another of the perforations becomes steam and allows applications such as pressure steam cooking, steam compression or steam generators and engines, hot water or heating. The energy by conduction allows applications such as the pyrolytic cleaning of the oven, the incineration of garbage or ceramic hobs of the kitchen.
    [0044]
    [0045] The materials used in the manufacture of the components of the stabilized thermal collector, their shapes and dimensions, and all the accessory details that may arise, are independent of the object of the invention, as long as they do not affect their essentiality.
