Abstract
The invention relates to a novel high-efficiency solar water heater, belonging to the field of the manufacture of solar heaters. The novel high-efficiency solar water heater comprises vacuum pipes, high-efficiency energy-storage materials, a heat exchanger, a clamping seat, a header, and sealing gaskets. When sunlight irradiates to the solar vacuum pipes, the solar energy can be temporarily stored in the high-efficiency energy-storage materials, when the water temperature in the heat exchanger is lower than a set temperature and the temperature of the high-efficiency energy-storage materials is higher than the set temperature, the heat energy in the high-efficiency energy-storage materials can be emitted out to heat water in the heat exchanger to the set temperature, and after the water temperature in the heat exchanger reaches the set temperature, the high-efficiency energy-storage materials stop emitting the heat, and meanwhile, the solar energy absorbed by the vacuum pipes is stored into the high-efficiency energy-storage materials, therefore the purpose of the solar water heater is achieved.
Description
Technical field:
The present invention relates to a kind of high efficiency solar water heater, utilize the high-efficiency energy-storage material directly to absorb solar energy and heat-exchanger rig is changed into hot water water heater for people to use with the heat energy of high-efficiency energy-storage material storage by heat-exchanger rig.Belong to solar heater and make the field.
Background technology:
Raising along with people's environmental protection and energy saving consciousness, various regenerative resources have obtained utilizing widely, solar water heater is exactly wherein a kind of, it is a kind ofly novel can give birth to clean energy resource, be widely used in the daily life, no matter the spring, summer, autumn and winter solar water heater brings a large amount of hot water, daily life easily to us.The whole employing of the solar water heater of Shi Yonging is to utilize solar energy with the direct-fired mode of water in the market, because the thermal capacitance value of water is lower, people are in order to obtain more hot water, adopt large water tank that the heat that solar energy produces is stored, not only increased the cost of solar energy, strengthened taking up room of solar energy simultaneously, the utilization of solar energy is restricted.The invention provides a kind of solar water heater of new property, it utilizes the high-efficiency energy-storage material directly to absorb the heat of solar energy and the heat of solar energy is stored, by heat-exchanger rig with the thermal energy transfer that stores in cold water, the temperature of cold water is improved, reach the purpose that hot water is provided to people, this method has simple in structure, characteristics such as volume is little, reliability is high, long service life, cost are lower.
Summary of the invention
The purpose of this invention is to provide a kind of high efficiency solar water heater, utilize high-efficiency energy-storage material in the vacuum tube to absorb and storage solar energy and by heat-exchanger rig the heat energy of energy storage material storage is changed into the hot water people and use, have stable water outlet, volume is little, reliability is high advantage.
To achieve the object of the present invention, the technical scheme that the present invention uses is: solar water heater is by vacuum tube, deck, header, compositions such as sealing gasket, it is characterized in that: the central interior at vacuum tube is equipped with heat exchanger, filling the high-efficiency energy-storage material around the heat exchanger and between the inwall of vacuum tube, sealing gasket is equipped with in inside on the top of the top of high-efficiency energy-storage material vacuum tube, the delivery port of heat exchanger and the water inlet central authorities by sealing gasket with connect case and be connected, header is positioned at the top of heat exchanger, and the bottom of header is connected with the upper end of vacuum tube.When solar irradiation is mapped to solar energy vacuum tube, the emittance of the sun is absorbed by the high-efficiency energy-storage material, when people use hot water, the cold water that enters from water inlet enters into heat exchanger through header, exchange by heat exchanger with the thermal energy transfer of the solar energy of the absorption in the high-efficiency energy-storage material in cold water, the temperature of water is raise, thereby reach purpose the water heating.
The heat exchanger of vacuum tube inside can be a different shape among the present invention, and its purpose is exactly the water that the heat energy in the high-efficiency energy-storage material is entered into interchanger by exchange.
Among the present invention vacuum tube inside and heat exchanger between the high-efficiency energy-storage material be meant the object that object carries out energy storage by the variation of the crystal grain of phase transformation or object, its form is the mixture of solid, liquid, gas or solid and liquid.
Vacuum tube of the present invention is meant with one or connects into the integral body of forming by a plurality of vacuum tubes that the connected mode of the integral body that a plurality of vacuum tubes are formed is modes such as spiral, welding.
Outside at vacuum tube of the present invention increases cover plate, can play the protective effect to vacuum tube, can improve security of the present invention.
The invention has the beneficial effects as follows: solar energy is stored by the high-efficiency energy-storage material in the vacuum tube and be heated to design temperature, have stable water outlet, volume is little, reliability is high advantage what the water in the heat exchanger continued.
Description of drawings
Figure: side of the present invention is cutd open schematic diagram
Among the figure: 1 vacuum tube, 2 high-efficiency energy-storage materials, 3 heat exchangers, 4 decks, 5 headers, 6 sealing gaskets.
The specific embodiment
At first the bottom of vacuum tube (1) is contained in the inside of deck (4), the bottom of heat exchanger (3) is contained in the central interior of vacuum tube (1), be filled in the space of the bottom of vacuum tube (1) inside and heat exchanger (3) with high-efficiency energy-storage material (2), sealing gasket (6) is equipped with in inside in vacuum tube (1) upper end, the outlet pipe of heat exchanger (3) links to each other with oral siphon with other outlet pipes with the centre that oral siphon is worn sealing gasket (6), be contained in header (5) in the upper end of vacuum tube (1), the header that passes through (5) is connected to form one group of solar energy whole with several vacuum tubes (6).So far solar water heater of the present invention all assembling finishes.
During use, when solar irradiation is mapped to solar energy vacuum tube (1), the radiant energy of the sun will be absorbed at high-efficiency energy-storage material (2), when cold water process heat exchanger (3), the solar energy that high-efficiency energy-storage material (2) absorbs will pass through heat exchanger (3) and discharge, and with the heating of the cold water of heat exchanger (3), when the release temperature of water temperature in the heat exchanger (3) and high-efficiency energy-storage material (2) equates, high-efficiency energy-storage material (2) stops by the release of heat exchanger (3), supplies with people's use by the absorption and the release of high-efficiency energy-storage material (2) heating by the cold water in the heat exchanger (3).Facts have proved that the solar water heater that this kind method produces is easy for installation, volume is less, reliable operation not only, and also cheap.
