Abstract
The utility model discloses a self-cleaning evacuated collector tube solar water heater, belonging to the field of solar thermal applications. The heater mainly solves the problems that the evacuated solar water heater is always accumulated with old water and dirt to lead to water quality deterioration, the water and dirt can not be fully discharged and the hot water utilization is not high. The heater is characterized in that two ends of the evacuated collector tube 2 thereof are open and provided with a heat storage water tank 7, a used water tank 4 and an evacuated tube 3. When water inflows, tap water is injected into the used water tank 4 from an inlet and outlet pipe 5; when water flows out of an exhaust and overflow pipe 6, inflowing is stopped; under the radiation of the sunshine, the hot water in the evacuated collector tube 2 enters the heat storage water tank 7; and the lower-temperature water at the bottom of the heat storage water tank 7 enters the used water tank 4 from the evacuated tube 3, therefore, hot water and clod water can conduct convective heat transfer. When the water is used, the water is discharged from the inlet and outlet pipe 5, high-temperature water flows out through the evacuated collector tube 2 with two ends being opened and the evacuated tube 3. Through the cold and hot water heat transfer and the water using process, the goal of cleaning the evacuated collector tube is achieved automatically by the upper and lower convection of the water.
Description
Technical field
The utility model belongs to solar energy heat utilization field, relates to a kind of energy automatically washing vacuum heat collection tube solar water heater.
Background technology
In the prior art, conventional vacuum heat collection pipe solar water heater mainly is made up of thermal storage water tank, vacuum heat collection pipe and support three parts, the structure of vacuum heat collection pipe is the glass heat-collecting vacuum tube structure that adopts an end to seal an end opening, the openend of each vacuum heat collection pipe inserts the thermal storage water tank respectively, and blind end is mutually independent and can not be communicated with, entery and delivery port all is located on the thermal storage water tank, the hot water that system can only limit to store among the thermal storage water tank with hot water, the hot water of storing in the vacuum heat collection pipe all are difficult to utilization because of discharging.As time goes on, the highest water temperature is but descending year by year under equal sunlit condition, and it is that gathering of vacuum heat-collecting inside pipe wall incrustation scale thickens and make due to its heat transmission function weakens that water temperature descends.Because the structure of existing vacuum heat collection pipe is end sealing, water is difficult to circulation therein, last a very long time, calcium magnesium electrodeposition substance in the water is at the pipe end and tube wall, accumulate over a long period, impurity in incrustation scale and the water will slowly be deposited in the vacuum heat collection pipe, and the initial good solar collecting performance of vacuum heat collection pipe will fade away.Water pipe is contained in the vacuum heat collection pipe upper tank, when water, the hot water in the vacuum heat collection pipe can not be emitted all the time, causes water quality deterioration, breed bacteria in the solar water heater, influences making full use of of solar water heater, has also just reduced the thermal efficiency.
Summary of the invention
A kind of energy automatically washing vacuum heat collection tube solar water heater is provided, by changing the structure of vacuum heat collection pipe and solar water heater, adopt the vacuum heat collection pipe of dual-end, can overcome the deficiencies in the prior art, all flowed out utilization with making in the system on the water tank by the hot water of solar energy heating with what inlet tube and outlet tube was installed in the vacuum heat collection pipe bottom, can make and not accumulate Chen Shui and incrustation scale in the vacuum heat collection pipe, heat energy makes full use of, avoid growing of bacterium, and the raising thermal efficiency makes the vacuum heat collection pipe solar water heater can keep efficient for a long time normal operation.The purpose of this utility model is to quicken water flowing in vacuum heat collection pipe, avoid incrustation scale at the bottom of the vacuum heat collection pipe pipe and the deposition of tube wall, when vacuum heat collection pipe absorbs heat, utilize the principle of hot water come-up, water automatically washing vacuum heat collection tube in heat transfer process in solar water heater inside.Form by the vacuum tube support of the vacuum heat collection pipe of the thermal storage water tank with exhaustion spill, dual-end, dual-end and with water tank, it is characterized in that: the one, its vacuum heat collection pipe both-end is an opening; The 2nd, it has two water tanks, thermal storage water tank and use water tank, the thermal storage water tank is positioned at the top of support, is positioned at the support below with water tank, the vacuum heat collection pipe by several dual-ends arranged side by side, vacuum tube by certain angle and thermal storage water tank be connected with water tank; The 3rd, vacuum tube is installed in the centre position of solar water heater.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Among the figure: 1 is water, and 2 is the vacuum heat collection pipe of dual-end, and 3 is the vacuum tube of dual-end, and 4 for to use water tank, and 5 is inlet tube and outlet tube, and 6 are exhaust, overflow pipe, and 7 is the thermal storage water tank, and 8 is support.
The specific embodiment
As shown in the figure, technical solution of the present utility model is that existing vacuum heat collection pipe water heater structure is improved.Its feature one is that its vacuum heat collection pipe 2 both-ends are openings; Its feature two is that it has two water tanks, thermal storage water tank 7 and with water tank 4, thermal storage water tank 7 is positioned at the top of support 8, is positioned at support 8 belows with water tank 4, presses certain angle and thermal storage water tank 7 and is connected with water tank 4 by vacuum heat collection pipe 2, the vacuum tube 3 of several dual-ends arranged side by side.Its feature three is both sides that vacuum tube 3 is installed in solar water heater, does not possess heat collection function.Because vacuum heat collection pipe 2 of the present utility model and vacuum tube 3 both-ends are openings, thermal storage water tank 7 is inserted in the upper end, insert with water tank 4 lower end, thermal storage water tank 7 and with vacuum heat collection pipe 2, the vacuum tube 3 of water tank 4 and dual-end formed one mobile during for heat exchange by the circular passage shown in the reference arrow.During water inlet, to injecting running water,, stop into water from inlet tube and outlet tube 5 when exhaust, when overflow pipe 6 there are flowing out with water tank 4, under the irradiation of sunlight, hot water in the vacuum heat collection pipe 2 enters thermal storage water tank 7, and the water at low temperature of thermal storage water tank 7 bottoms enters with water tank 4 from vacuum tube 3, and hot and cold water is heat convection so constantly, therefore, calcium ions and magnesium ions compound in the water just is difficult to be deposited in the vacuum heat-collecting inside pipe wall, more can not be deposited in the pipe end, reduces the formation of incrustation scale.During water, discharge water from inlet tube and outlet tube 5, high-temperature water flows out simultaneously by the vacuum heat collection pipe 2 and the vacuum tube 3 of dual-end, finishes the purpose by automatically washing vacuum heat collection tube in heat exchange and the water utilizing process.
The utility model compared with prior art, the vacuum heat-collecting in-tube fouling reduces, and avoids water quality deterioration in the solar water heater, and the vacuum heat collection pipe of prolongation service life is arranged, and forever protects the characteristics such as result of use, especially the relatively poor region of water quality is had more superiority. Because inlet tube and outlet tube is installed in the water tank of using of bottom, is conducive to the combination of building.
