Household photo-thermal device

Technical Field

The utility model belongs to the technical field of the light and heat utilization, especially, relate to a domestic light and heat device.

Background

Under the current situation of the world energy crisis, developed countries and regions increasingly pay more attention to the development and utilization of solar energy, and thus photo-thermal conversion devices are in force. Since 1945 photo-thermal conversion devices are popularized and applied, solar photo-thermal devices are continuously updated.

Solar energy is a clean energy source, and the energy radiated to the earth by the sun per second reaches 1.465 × 10¹⁴Joules, equivalent to the sum of 500 kilotons of coal. Fossil fuels used by mankind since the industrial revolution to date are also derived from solar energy. However, the energy conversion efficiency of nature is extremely low, and it often takes tens of thousands of years to form an energy source which can be applied to industry, so that it is very important to find a high-efficiency solar energy collection and conversion mode.

The photothermal device is a device which converts solar energy into thermal energy through a specific light-gathering device, thereby heating a medium (liquid or gas) in an absorber to a higher temperature, and then directly utilizing the heating medium or driving other devices to generate energy in the form of electric energy, mechanical energy and the like. The photo-thermal structure can be divided into flat plate type and vacuum tube type heat collectors.

The solar photo-thermal device can well convert solar energy into heat energy for utilization, and has the difficulty that how to more efficiently absorb the solar energy and how to convert the solar energy into the heat energy under the condition of reducing loss as much as possible. At present, the heat absorption efficiency of most of the photothermal devices on the market needs to be improved, and the blue film coating produced by the German magnetron sputtering technology has extremely high absorption and conversion efficiency, but is difficult to popularize and apply to the industry.

Disclosure of Invention

The utility model aims to solve the technical problem that a domestic light and heat device is provided, simple structure can carry out high-efficient heat absorption and heat conversion.

The utility model provides a technical scheme that its technical problem adopted provides a domestic light and heat device, including basin, water pump, conduit, heat exchange tube, black backplate, wire, black coating, outlet conduit and water tank, the heat exchange tube is continuous U type, the water pump sets up in the basin, conduit one end is connected with the water pump, the other end and heat exchange tube intercommunication, outlet conduit one end and heat exchange tube intercommunication, the other end and water tank intercommunication, the outer wall of heat exchange tube scribbles black coating, inside and has laid mutual interval between a plurality of wires and a plurality of wire along the tube side, the side of being shaded of heat exchange tube is equipped with the black backplate.

The black back plate is a hard plate, and the heat exchange tube is installed on the black back plate through a connecting fastener and is attached to the plate surface.

And spacing brackets are arranged among the plurality of metal wires at intervals along the extension direction.

The metal wires are three aluminum wires.

Advantageous effects

The utility model discloses in, wire, black coating, the inside rivers of heat exchange tube and external black backplate have formed a hot system altogether, shine when the heat exchange tube when the sunlight, and a large amount of solar energy can be absorbed with the black backplate to can turn into the heat energy of rivers with solar energy. In addition, the built-in metal wire of the heat exchange tube can disperse water flow on one hand, so that the cross section area and the turbulence characteristic of the water flow are increased, and on the other hand, the metal wire has the characteristic of high heat conduction speed, so that the uniformity and the efficiency of water flow heat exchange are improved. Therefore, the utility model discloses simple structure can carry out high-efficient heat absorption and heat conversion.
