Abstract
The utility model discloses an automatic solar energy temperature difference cycling device of a solar water heater and belongs to the technical field of accessories of solar water heaters. The automatic solar energy temperature difference cycling device is connected with a lower water pipe and an upper circulating pipe of a water storage tank of the solar water heater. The automatic solar energy temperature difference cycling device is characterized by comprising a solar heating tank which is composed of a tank body made of thermal insulation materials and a transparent glass cover plate, a bent black metal heat collecting tube or a vacuum glass heat collecting tube is internally arranged, an inlet of the heat collecting tube 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 collecting tube is communicated with upper layer water body of the water storage tank of the solar water heater through the upper circulating pipe, and the device can operate without driving by a power supply. The automatic solar energy temperature difference cycling device is simple in structure, reliable in operation, convenient to use and fast in hot water discharging.
Description
Technical field:
The utility model 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 for vast resident family, is also that country actively advocates the Green Product of promoting, it further be 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 effective heat-insulation and heat-preservation and process, heat radiation is serious.On the other hand because the 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 cold water that the bottom of storage barrel always has the insufficient heating of a certain amount of convection current conduction exists.Cause like this except discontinuous use water outlet, when use at the interval, 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 the circulating pump forced circulation to reach up and down 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 purpose that efficient is the present invention.
The utility model content:
In order to address the above problem, the utility model provides a kind of 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 scheme that adopts of the utility model is:
Solar water heater solar energy temperature difference automatic circulation device, it is connected with upper circular tube with the downcomer of solar water heater water storage tank.It is characterized in that comprising a solar energy heating case, casing and the clear glass cover plate made by heat-barrier material consist of; 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; Outlet is communicated with the upper strata water body of solar water heater water storage tank by upper circular tube, and the device operation need not power drives.
Effective effect of the present utility model 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, need not power drives.
Below in conjunction with the drawings and specific embodiments to further detailed explanation of the utility model.
Description of drawings:
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment:
As shown in Figure 1, one embodiment of the utility model solar water heater solar energy temperature difference automatic circulation device, 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 consist of with clear glass cover plate 6, built-in black bending metals thermal-collecting tube 7 or glass heat-collecting vacuum tube, its import and solar water heater water storage tank 1 downcomer 2 bottoms are connected, 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 subjected to hot water because action of thermal difference moves upward, enter the upper water body of solar water heater water storage tank 1 by upper circular tube 3, also there is the natural temperature differential of upper heat and lower cold due to the water body of water storage tank 1, the next colder water body of water storage tank, equally enter black bending metals thermal-collecting tube 7 due to action of thermal difference by downcomer 2 or glass heat-collecting vacuum tube is filled up the space that shifted out by hot water, again by the backward upper motion of solar energy heating of black bending metals thermal-collecting tube 7 or glass heat-collecting vacuum tube absorption, continuous automatic cycle, last reach gradually forgive in water storage tank 1 interior up and down water body and circulating line water body etc. temp effect, as long as solar energy and the existence of the temperature difference at sunshine is arranged, this automatic cycle will can not stop, need not power drives.Simultaneously, because the collector area that has enlarged solar water heater also can play gain of heat effect.
