<p>The collector is used in solar energy engineering for heating of liquid and gaseous fluids for residential and industrial needs. It operates as an element to a comprehensive heating system. It consists of two semispherical or part of semisphere shells closed by means of a flange connection. The upper shell is made of glass (1) and the lower one is metal (2) with a cock-union for vacuum formation (5). A metal accumulator-radiator (3) is mounted in the space between the two shells through the coil of which the heat carrier is running. The inlet and outlet pipes for cold and hot fluid are welded to the lower metal shell. The surface of the accumulator-radiator is covered by a layer of elementary amorphous carbon - carbonblack, and its exact fixing in the space between the shells is made by means of fixing parts (4) which apart from this function also form part of the atmospheric counter pressure inside the collector. The vacuum in the system is guaranteed from the airtight sealing (8) between the flanges. Brackets (7), the number of which depends on the size of the collector, and the plastic screws (6) secure the flanges of the collector and exercise pressure before the vacuum formation, or in case of vacuum adulteration. The collector can operate as part of a battery system in consecutive connection for increasing the fluid temperature, parallel connection for increasing the discharge and mixed connection. The overall dimensions and the external configuration of the collector can differ and solely depend on the architectural and civil engineering requirements of the space needed for the assembly. 1 claims, 1 figures</p> |
