RU2330217C2 - Solar collector - Google Patents

Abstract

FIELD: heating.

SUBSTANCE: invention refers to energy conservation techniques by means of using solar energy for heating of a heat carrier in operating systems and systems being under development designed for hot water supply and heating with a forced circulation of liquid facilitating an intensive heat-and- mass transfer. A collector-distributor included in the structure of the solar collector is made out of non ferrous metals (aluminium, copper and others) by method of pressure die casting; the collector is connected to heat collecting pipes and to pipes of the system of heat carrier transfer to consumers through joining of attached parts along contacting surfaces by means of isolating them from one another with a thin adhesive film of 0.1 to 0.5 mm thickness.

EFFECT: reduction of prime cost and labour input at fabricating and assembly of a solar collector.

Description

The invention relates to energy saving through the use of solar energy for heating a coolant located in existing and planned hot water supply and heating systems with forced circulation of the liquid, providing intense heat and mass transfer.

Currently known solar collectors (SC) are made in the form of solid metal panels, the working surface of which has a light-absorbing coating (blackening, etc.), to which are attached separate heat-collecting tubes of non-ferrous metals (aluminum, copper and their alloys) with welded to them by the pipes of the input and output collector-distributor, providing the transfer of the heated and reception of the cooled mass of liquid from consumers.

A disadvantage of the known SK is:

- technological complexity and high complexity of welding of structural elements from non-ferrous metals;

- the irrationality of the design, which necessitates the creation of a complex system of pipeline connections, coupled with heat losses in them and causing additional energy losses to overcome hydraulic resistance.

The technical problem to which the invention is directed is to reduce the cost and complexity of manufacturing and assembling SC, increasing the heat capacity of the liquid circulating in the SC. The problem is solved in the fact that in the design of the SK collector-distributors are made of non-ferrous metals (aluminum, copper, etc.) by injection molding, and for pairing with heat-collecting tubes and pipes of the heat transfer system to consumers, special quick-mount threadless coupling connectors are used that provide the ratio deformations between the contacting surfaces of parts within elastic deformation, and in order to eliminate the risk of depressurization of compounds in conditions of temperature fluctuations and violation of dimensional ratios in the connection zone, the mating parts along contacting surfaces are insulated from each other by adhesive film with a thickness of 0.1 to 0.5 mm.

The drawing shows an SC consisting of a working panel 1, heat-collecting tubes 2, a manifold-distributor 3 with nozzles 4, 5, connectors 6, a protective screen 7, a heat transfer pipe to consumers 8.

Preparation of the SC for work starts from the moment it is delivered to the place of operation; installation and orientation in accordance with the design requirements; connecting the nozzles 5 of the collector-distributor to the coolant supply-reception system; filling the system with coolant and turning on the system of its automatic pumping when the set temperature is reached.

After heating the coolant to a predetermined temperature, its movement to consumers begins.
