Description

A combined solar gas-liquid heat collector

technical field

The utility model relates to a solar heat utilization device, in particular to a combined solar gas-liquid heat collector.

Background technique

Solar collectors are an important part of solar thermal utilization systems, which are divided into air collectors and liquid collectors, which directly heat air or liquid working fluid. As an air collector, it is generally used for solar drying, building heating, etc., while a liquid collector is often used for solar water heaters or solar hot water systems. At present, the air collector and the liquid collector are used separately, so the function is relatively single, and the heat energy has not been fully utilized.

Contents of the invention

The technical problem to be solved by the utility model is to provide a combined solar gas-liquid heat collector, which can be used as an air heat collector for solar drying, building heating, etc., and can also be used as a liquid heat collector for solar water heaters or solar hot water system, and its structure is simpler and more reliable, and it is more convenient to realize the building construction of solar collectors integrating solar energy and buildings.

The solution adopted to solve the technical problems of the utility model is: on the basis of conventional solar heat collectors composed of frames, transparent cover plates, insulation layers and plate cores, it is improved to set air heat collecting plate cores and a heat collecting plate core in the frame space at the same time. A series of metal heat-absorbing tubes are combined to form a collector plate core, and the heat-absorbing tubes are connected with the hot water tank. A series of heat-absorbing fins are fixed on the heat-absorbing pipe to increase the heat-absorbing efficiency of the device.

When the collector works, the collector plate core converts solar radiation into heat energy, the air heat collector plate core transmits heat to the air, and the heat-absorbing tube can absorb heat from the hot air while receiving solar radiation. Therefore, the heat collector not only produces hot air, but also provides hot liquid working medium, which can not only lead the hot air into the room for heating, but also generate hot water through the liquid working medium.

The beneficial effect of the utility model is: the plate core mainly adopts the solar air heat collector, which has simple structure, high reliability, and the same service life as the building, and lays a technical foundation for building construction using solar light and heat. In addition, the utility model combines solar building heating with hot water supply, which improves the practicability of the system.

Description of drawings

Accompanying drawing 1 is the side sectional schematic diagram of the utility model embodiment,

Accompanying drawing 2 is the front schematic view of the utility model embodiment.

Each label in the figure indicates: frame 1, transparent cover plate 2, insulation layer 3, heat collector plate core 4, air heat collector plate core 5, heat absorbing pipe 6, air outlet 7, air inlet 8.

Detailed ways

Referring to Figures 1 and 2, the heat collector is assembled from a frame 1, a transparent cover plate 2, an insulation layer 3, and a heat collector core 4, wherein the heat collector core 4 is composed of an air heat collector core 5 and a heat-absorbing plate core 5. Tube 6, which is set in the space of frame 1, and fins are fixed on the heat-absorbing tube 6. When the collector is working, its collector plate core 4 converts solar radiation into heat energy, and the air heat collector plate core 5 converts heat The heat-absorbing pipe 6 can also absorb the heat in the hot air while receiving the solar radiation. Therefore, the collector can adopt the following three operation modes according to different needs: ①Use as a solar water heating system, the hot air The heat in the heat is used to heat the liquid working medium through the heat-absorbing tube 6 to produce hot water. This method is used in non-heating seasons; ②Used as a solar air heat collector, the heat collector only generates hot air, and the hot air passes through the air The outlet 7 leads to indoor heating, which is used in the heating season; ③ Combined application, the collector generates hot air and hot water through the hot water system, and the hot air is introduced into the indoor heating, while supplying hot water, this method It is used for both heating seasons.

The utility model is not limited to the specific embodiments described above.
