Abstract

Thermal dissipater for installations of solar energy collection based on thermal collectors. Intended to prevent the temperature from exceeding a pre-established level in the primary circuit (2-4) of a thermal collector-based installation (1), it consists of a radiator (11) interleaved in a branch (10) of the primary circuit (2). -4) provided with a safety valve (15), said branch (10) having a branch (12) in which a two-way valve (13) is established, controlled by a thermostat (14) that detects the temperature in the primary circuit (2), radiator (11) that at its outlet (16) incorporates a check valve (17) before connecting to the return (4) of the primary circuit, bypassing the plate exchanger (3). In this way, a static dissipator is obtained, which does not require the classic fans, which consequently do not consume energy, controlled by valves acting by pressure difference, so that they do not need electrical power either.

Description

Disipador térmico para instalaciones de captación de energía solar a base de colectores térmicos.Heatsink for installation of solar energy collection based on thermal collectors.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un disipador térmico, aplicable en instalaciones de captación de energía solar que utilizan como captadores colectores térmicos en los que la captación se lleva a cabo mediante un líquido calo-portador que circula por una serie de tubos debidamente intercomunicados.The present invention relates to a heatsink thermal, applicable in solar energy collection facilities which use thermal collectors as collectors in which the uptake is carried out by a liquid calo-carrier that circulates through a series of tubes duly intercommunicated

El objeto de la invención es conseguir evitar que la temperatura en la instalación supere una cota preestablecida, como por ejemplo los 60º, y que esto se produzca de forma automática, en ausencia de consumo energético.The object of the invention is to avoid that the temperature in the installation exceeds a level preset, such as 60 degrees, and that this occurs in automatically, in the absence of energy consumption.

Antecedentes de la invenciónBackground of the invention

Convencionalmente los colectores solares térmicos están constituidos mediante una carcasa, a modo de cajón, generalmente de aluminio, con su fondo convenientemente termo-aislado, mediante lana de roca u otro material apropiado, estableciéndose sobre dicho material aislante una pluralidad de tubos, generalmente paralelos y de cobre, que relacionan un colector de entrada y un colector de salida, conectándose varios colectores térmicos en paralelo a un circuito cerrado, por el que circula un líquido calo-portador, pasante a través de un intercambiador que transmite la temperatura, mas concretamente el calor de que es portador el citado líquido, a un circuito de agua donde se sitúan acumuladores que permiten el consumo de la misma, como medio de calefacción, agua sanitaria, etc.Conventionally solar collectors thermal are constituted by a housing, as a drawer, usually aluminum, with its bottom conveniently thermo-insulated, by rock wool or other appropriate material, settling on said insulating material a plurality of tubes, generally parallel and of copper, which relate an input manifold and an output manifold, connecting several thermal collectors in parallel to a circuit closed, through which a liquid circulates heat carrier, through an exchanger  which transmits the temperature, more specifically the heat of which it is carrier said liquid, to a water circuit where they are located accumulators that allow the consumption of it, as a means of heating, sanitary water, etc.

Estas instalaciones para captación de energía solar están previstas para trabajar en un rango de temperaturas que no debe de sobrepasar ciertas cotas, generalmente la cota de los 60ºC, ya que por encima de tales temperaturas existen riesgos de daño tanto para los propios paneles solares como para el resto de la instalación, sobre todo teniendo en cuenta que en condiciones de radiación solar muy favorables la temperatura en el circuito primario podría llegar a alcanzar los 300ºC.These facilities for energy collection solar are planned to work in a range of temperatures that must not exceed certain levels, usually the level of 60 ° C, since above such temperatures there are risks of damage to both the solar panels themselves and the rest of the installation, especially considering that in conditions of solar radiation very favorable temperature in the circuit Primary could reach 300ºC.

Hasta la fecha y para conseguir controlar este incremento indeseado de la temperatura de la instalación, se utilizan aero-termos, consistentes en una batería de agua que se calienta a expensas de la temperatura del sistema, y un ventilador que disipa el calor acumulado en dicha batería de agua.To date and to get control of this unwanted increase in installation temperature, it they use aero-thermos, consisting of a battery of water that is heated at the expense of the system temperature, and a fan that dissipates the heat accumulated in said battery of Water.

Esta solución si bien resulta viable desde el punto de vista de los resultados prácticos obtenidos, presenta como problema fundamental el hecho de que requiere ineludiblemente de aportación de energía eléctrica para alimentar tanto al ventilador como a la válvula que permite o cierra el paso de agua a través del mismo.This solution although it is viable from the point of view of the practical results obtained, presents as fundamental problem the fact that it inevitably requires contribution of electrical energy to power both the fan as to the valve that allows or closes the passage of water through the same.

Descripción de la invenciónDescription of the invention

El disipador térmico que la invención propone resuelve de manera plenamente satisfactoria la problemática anteriormente expuesta, al no requerir de energía eléctrica para su funcionamiento, puesto que tampoco requiere de la presencia de un ventilador, y el necesario sistema valvular utiliza, en lugar de las clásicas electroválvulas, válvulas que actúan por diferencia de presión.The heatsink that the invention proposes solves the problem fully satisfactorily previously exposed, not requiring electrical energy for operation, since it also does not require the presence of a fan, and the necessary valve system uses, instead of the classic solenoid valves, valves that act by difference of Pressure.

La estructura descrita se complementa con una válvula de retención situada a la salida del radiador, en un conducto de retorno hacia los colectores térmicos, que puentea el intercambiador de placas, desembocando en la conducción de retorno hacia los citados colectores térmicos, entre el intercambiador de placas y la clásica bomba de recirculación de agua del circuito primario de la instalación.The structure described is complemented by a check valve located at the outlet of the radiator, in a return duct to the thermal collectors, which bridges the plate exchanger, leading to return conduction towards said thermal collectors, between the heat exchanger plates and the classic circuit water recirculation pump Primary installation.
