Definitions

• the invention relates to solar technology, in particular to devices for converting solar energy into heat, and can be used to heat water in a domestic environment.
• a disadvantage of the known solar collector is that it heats up water from a solar radiation through a light-absorbing coating, i.e. lack of heat storage ability.
• the closest analogue of the claimed device is a flowing solar collector containing a housing with a translucent cover of the lid and a corrugated wall inside. Between the base of the case and the corrugated wall there is a heat accumulator - in the form of a substance with a phase transformation - paraffin. Heated water is fed inside the solar collector into a flow-through heat exchanger formed by a lid and a corrugated wall (Pat. RF Ne 2230263 C2, IPC 7 F24J 2/34, op. 10.06.2004).
• Common essential features of the known and claimed devices are a heat-insulating housing, a translucent enclosure, a heat accumulator in the form of a substance with a phase transformation, and a flow heat exchanger.
• the basis of the invention is the task of improving a flow solar collector, in which by using material to absorb sunlight and changing the design and location of the heat exchanger, heat losses are reduced during its accumulation and heating of the liquid, as a result of which an increase in the efficiency of use of solar energy is achieved.
• the problem is solved in that in a flowing solar collector containing a heat-insulating casing, a translucent enclosure, a heat accumulator in the form of a substance with phase transformation and a flow heat exchanger, in accordance with the invention, at least one surface of the heat accumulator is covered with selective light-absorbing material, elements are installed in the heat accumulator that conduct thermal energy from a selective light-absorbing coating into a substance with a phase transformation, and from it into a liquid of a flowing heat exchanger, and which are flow elements heat exchanger.
• a eutectic mixture is used as a substance with a phase transformation.
• a gel based on sodium acetate hydrate was used as a eutectic mixture.
• fins connected in a package made of heat-conducting material are used as elements of a flow-through heat exchanger.
• a eutectic mixture as a phase-conversion substance, for example, a gel based on sodium acetate hydrate, provides a decrease in the melting energy of a phase-conversion substance due to the fact that the melting temperature of a solid eutectic mixture is always lower than the melting temperature of a mixture of any other composition, which also helps to reduce losses heat.
• FIG. 1 shows a General view of a flowing solar collector; in FIG. 2 - its frontal section.
• the flowing solar collector (Fig. 1, 2) contains a thermally insulated housing 1 with a translucent fence 2. Inside the housing 1 there is a heat accumulator 3 with a filler in the form of a substance with a phase transformation - a eutectic mixture. It can be a gel based on sodium acetate hydrate.
• the heat accumulator 3 is provided with a selective light-absorbing coating 4 and a flow-through heat exchanger 5, through which heated water flows as needed.
• the coating 4 is made of a material with a high absorption coefficient and low reflection coefficient, for example, from blackened copper, and the heat exchanger 5 is placed inside the heat accumulator 3 and has a flow pipe 6 and fins 7 made of a heat-conducting material, such as metal, connected in a package. Water flows through the pipe 6 only when the consumer needs it.
• the process of charge-discharge of the heat accumulator occurs in this way - a quick set of temperature and its stabilization during the charge and, conversely, a long flat phase of the discharge temperature, which does not need additional regulation or stabilization .
• the discharge of the heat accumulator 3 is characterized by two phases: the first discharge is the supercooling of the mixture with heat transfer to the consumer, the second discharge is the recrystallization of the eutectic mixture at the moment that the consumer needs.
