Abstract
The invention provides a solar thermal collector. A tubular fluid flow passage is not adopted by a heat collecting water tank of the thermal collector, and space structure of the heat collecting water tank is improved. The solar thermal collector is high in heat transfer efficiency, and quick in water temperature rise. The solar thermal collector comprises heat collecting plates and the heat collecting water tank, the heat collecting plates are arranged on the upper layer of the heat collecting water tank, the heat collecting water tank has closed space which is defined by the heat collecting plates and galvanized iron sheets which are arranged on the periphery and on the bottom, the heat collecting water tank is provided with a water inlet pipe and a water outlet pipe, partition boards are arranged in water collecting space inside the heat collecting water tank, and an S-shaped water flow passage is formed by the partition boards.
Description
Technical field:
The invention belongs to energy technology field, be specifically related to a kind of solar thermal collector.
Background technology:
Flat-plate solar collector is a kind ofly to absorb solar radiation energy and to the device of working medium transferring heat, it is a kind of special heat exchanger, and the working medium in heat collector is carried out heat exchange with the sun at a distance.Flat-plate solar collector is comprised of absorber plate, shell, transparent cover plate, insulation material and relevant parts.
The basic functional principle of flat-plate solar collector is very simple, puts it briefly, and sunlight sees through transparent cover plate and shines on the absorber that the surface scribbles absorbed layer, wherein most of solar radiant energy is absorbed by absorber, change heat energy into, and pass to ducted water, like this, cold water from the heat collector bottom inlet, heated by sun the subject of knowledge and the object of knowledge in pipeline, temperature raises gradually, the water after heating, with the upper end outlet of useful heat energy from heat collector, hold in water storage tank stand-by.
On the absorber plate of existing writing board shape, usually all being furnished with comb and collector, is all the fluid passage of tubulose, and the passage of this tubulose, heat absorption efficiency are not high, and the speed of heating cold water is slow, and pipe is more, the waste material.
Summary of the invention:
Solar thermal collector of the present invention, the fluid passage of not using tubulose, but directly replaced the fluid passage of tubulose with space structure, and being provided with collecting space in the middle of absorber plate and bottom surface heat-insulation layer, collecting space is snakelike distribution.
Technical solution of the present invention is as follows:
A kind of solar thermal collector, comprise armorplate glass, collecting plate and heat collection water tank, collecting plate is positioned at the upper strata of heat collection water tank, heat collection water tank is the confined space that the galvanized iron sheet by collecting plate and surrounding and bottom surface surrounds, and heat collection water tank is provided with water inlet pipe and outlet pipe, it is characterized in that, the inner collecting space of heat collection water tank is provided with dividing plate, forms snakelike water stream channel by dividing plate.
Described water inlet pipe is located at the lower left of heat collection water tank, and outlet pipe is located at the upper right side of heat collection water tank.
The delivery port position of described outlet pipe is provided with temperature inductor.
The outer surface of the galvanized iron sheet of described surrounding and bottom surface all is provided with heat-insulation layer, and the heat-insulation layer material is phenol formaldehyde foam.
Described collecting plate surface is coated with water-repellent paint.
Also be provided with mineral wool layer or rock wool layer between described heat collection water tank and heat-insulation layer.
Described heat collector also is provided with temperature sensor and controls water outlet device.
Beneficial effect of the present invention:
1. the space structure of heat collection water tank of the present invention has directly replaced the fluid passage of tubulose, and it is snakelike that space structure is, and the water in space structure directly contacts with absorber plate, and heat transfer efficiency is high, and it is fast that water temperature rises.
2. space structure only needs dividing plate to be cut apart, and does not need pipe, and is simple in structure, also saved material simultaneously.
3. the serpentine waterways of heat collection water tank is beneficial to the hot water that will reach gradually temperature and ejects, and the cold water that newly advances continues heating.
