Abstract
The invention discloses a solar water heater and a solar temperature difference automatic cycle device, and belongs to the technical field of matching devices of the solar water heater. The solar temperature difference automatic cycle device is connected with a lower water pipe and an upper circulating pipe of a water storage tank of the solar water heater. The solar temperature difference automatic cycle device is characterized in that the solar temperature difference automatic cycle device comprises a solar heating tank, the solar heating tank is composed of a tank body made of heat insulating material and a transparent glass cover plate, a black bent metal heat collection pipe or a vacuum glass heat collection pipe is arranged in the solar heating tank, an inlet of the heat collection pipe is connected with the bottom end of the lower water pipe of the water storage tank of the solar water heater, an outlet of the heat collection pipe is communicated with upper layer water of the water storage tank of the solar water heater through the upper circulating pipe, and the device can run without being driven by a power source. The device is simple in structure, reliable in running, convenient to use and high in hot water go-out speed.
Description
Technical field:
The invention discloses a kind of solar water heater solar energy temperature difference automatic circulation device, belong to solar water heater corollary apparatus technical field.
Background technology:
The extensive use of solar water heater, cheap energy-conservation bathing equipment being provided to vast resident family, is also that country actively advocates the Green Product of promoting, it be further widely used, have good economic and social benefit, but, because the water storage tank of solar water heater is longer to the distance of delivery port, generally all more than ten meters, the outlet pipe wall of crossing through walls of still needing, full of twists and turns, be difficult to that it is implemented to effective heat-insulation and heat-preservation and process, heat radiation is serious.On the other hand because solar energy water storage tank relies on thermal-collecting tube convection current conduction storage heat, when night, sunlight disappeared, thermal convection current slows down and stops, and forms the distribution of water temperature of upper heat and lower cold, and the bottom of storage barrel always has the cold water existence that insufficient heating is conducted in a certain amount of convection current.Cause like this except discontinuous use water outlet, when interval is used, always have a large amount of cold water and exist, after opening delivery port, hot water delays to flow out like this, and cold water flowed out before this, this cool water quantity has not been a small amount of in extremely hot summer, in the winter of severe cold, even reach a very large amount, at least several liters, tens liters at most, then just have hot water and flow out and can take a shower, this not only causes the waste of valuable water resource, gives and uses the inconvenience that also brings level large.On the other hand, although also there is the temperature difference of utilizing circulating pump forced circulation to reach upper and lower water layer water temperature balanced at present, electric energy, material expend larger, and service life, not long result of use was unsatisfactory.How to solve the technology drawback that this is prevalent in solar water heater, reach easy to use, water saving, improve the result of use of solar water heater and the object that efficiency is the present invention.
Summary of the invention:
In order to address the above problem, the invention provides and a kind ofly can reach easy to use, water-saving a kind of solar water heater solar energy temperature difference automatic circulation device by solar energy temperature difference automatic cycle isothermal, to achieve these goals, the technical solution adopted in the present invention is:
Solar energy automatic temperature difference EGR, it comprises a solar energy heating case, built-in black bending metals thermal-collecting tube, or vacuum glass heat collection tube, the import of thermal-collecting tube is connected with the bottom of solar water heater water storage tank downcomer, and outlet is connected with the water storage tank of solar water heater through upper circular tube.
Effective effect of the present invention is the technology drawback that has solved existing solar water heater, and easy to use, water saving, supports the use with solar water heater, goes out hot water speed fast, without power drives.
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
Accompanying drawing explanation:
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment:
As shown in Figure 1, one embodiment of solar water heater solar energy temperature difference automatic circulation device of the present invention, the solar energy heating case 4 of its device, solar energy heating case 4 has the casing 5 that heat-barrier material is made to form with clear glass cover plate 6, the crooked thermal-collecting tube 7 of built-in ferrous metal or glass heat-collecting vacuum tube, its import is connected with solar water heater water storage tank 1 downcomer 2 bottoms, and its outlet communicates with the upper strata water body of solar water heater water storage tank 1 by upper circular tube 3;
The present embodiment utilizes black bending metals thermal-collecting tube 7 or the glass heat-collecting vacuum tube in solar energy heating case 4 to absorb solar energy, water body in heating black bending metals thermal-collecting tube 7 or glass heat-collecting vacuum tube, be subject to hot water because action of thermal difference moves upward, by upper circular tube 3, enter the upper water body of solar water heater water storage tank 1, because the water body of water storage tank 1 also exists the natural temperature differential of upper heat and lower cold, the next colder water body of water storage tank, equally because action of thermal difference enters black bending metals thermal-collecting tube 7 by downcomer 2 or glass heat-collecting vacuum tube is filled up the space that shifted out by hot water, after the solar energy heating of black bending metals thermal-collecting tube 7 or glass heat-collecting vacuum tube absorption, moved upward again, continuous automatic cycle, last reach gradually in the interior upper and lower water body of water storage tank 1 and circulating line, forgive water body etc. temp effect, as long as there is solar energy and the existence of the temperature difference at sunshine, this automatic cycle will can not stop, without power drives.Meanwhile, owing to having expanded the collector area of solar water heater, also can play gain of heat effect.
