Abstract
The utility model relates to a siphonic vacuum pipe solar water heater, which comprises a heat collecting water tank and a vacuum pipe, wherein the heat collecting water tank is provided with a water inlet and outlet pipe and an overflow pipe, a siphonic device is arranged in the heat collecting water tank, the siphonic device comprises a siphon arranged in each vacuum pipe, and a siphon connector arranged in the water tank, each siphon is connected with the siphon connector simultaneously, and the siphon connector is communicated with the water inlet and outlet pipe. A short-range siphon can also be arranged between the upper end of each vacuum pipe and the bottom of the heat collecting water tank. By a siphon principle, after hot water in the water tank of the solar water heater is used up, the hot water in each vacuum pipe can automatically flow out of the water tank for being used by people, so more than about 30% of hot water use amount can be increased under the same condition, and the effective heat gain in unit area can be increased to 10-14MJ/m2. In addition, when water is charged, the inner wall of the vacuum pipe can be flushed by the siphon so as to improve the heat absorption efficiency and reduce scale formation.
Description
Technical field
The utility model relates to a kind of solar utilization technique, particularly a kind of hydrocone type solar vacuum-tube water heater.
Background technology
Ordinary vacuum tube solar water heater on the present China market, its performance of employed glass-vacuum tube has been very outstanding, the absorptivity of its absorber coatings all reaches more than 90%, and the core technology index unit area of complete machine is effective that heat has only 7.5MJ/m
2About, domestic and international flat solar water heater is much lower for this numeric ratio.Want significantly to improve the effective heat that gets of vacuum pipe solar water heater unit are, just must consider to give full play to the thermal-arrest effect of each glass-vacuum tube.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of effective high energy efficiency hydrocone type solar vacuum-tube water heater that gets heat of unit are that can increase substantially under the same conditions.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of high energy efficiency hydrocone type solar vacuum-tube water heater, comprise heat collection water tank and vacuum tube, heat collection water tank is provided with water inlet pipe and water outlet pipe and overflow pipe, be characterized in: in heat collection water tank, be provided with siphoning installation, siphoning installation comprises and is located at the siphon pipe in every vacuum tube and is located at siphon pipe coupling device in the water tank, each siphon pipe joins with the siphon pipe coupling device simultaneously, and the siphon pipe coupling device is connected with water inlet pipe and water outlet pipe.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that siphon pipe inserts the interior length of vacuum tube more than or equal to 90 percent of vacuum tube length.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, is provided with the short distance siphon pipe between the bottom of the upper end of every vacuum tube and heat collection water tank.
The utility model compared with prior art, in every vacuum tube, all be provided with siphon pipe, utilize siphon principle, behind the hot water in using solar water heater water tank, it is for people to use to make hot water in every vacuum tube flow out water tank automatically, can increase about hot water use amount more than 30% so under the same conditions, its complete machine core technology index unit area is effective that heat can be brought up to 10～14MJ/m
2, surpass national standard more than 30%, significantly surpass GB one-level efficiency technical indicator simultaneously.When last water, can wash the vacuum tube inwall in addition, with heat absorption efficiency that improves vacuum tube and the generation that reduces incrustation scale by siphon pipe.

The specific embodiment
A kind of high energy efficiency hydrocone type solar vacuum-tube water heater, comprise heat collection water tank 5 and vacuum tube 1, heat collection water tank 5 is provided with water inlet pipe and water outlet pipe 6 and overflow pipe 3, in heat collection water tank 5, be provided with siphoning installation, siphoning installation comprises and is located at the siphon pipe 2 in every vacuum tube and is located at siphon pipe coupling device 4 in the water tank, each siphon pipe joins with siphon pipe coupling device 4 simultaneously, and siphon pipe coupling device 4 is connected with water inlet pipe and water outlet pipe 6.The siphon pipe coupling device can adopt down water flowing out structure as shown in Figure 1, also can adopt the upper water-out structure as shown in Figure 2; Can also adopt mode as shown in Figure 3 in the water outlet of the side of water tank.
The length optimum value that siphon pipe 2 inserts in the vacuum tube 1 is more than or equal to 90 percent of vacuum tube length.Siphon pipe 2 can be a metal, also can be nonmetal, as flexible pipes such as copper pipe, stainless steel tube or rubber plastics.
In order to guarantee that the hot water in the heat collection water tank all is utilized, between the bottom of the upper end of every vacuum tube and heat collection water tank, be provided with short distance siphon pipe 7.Can guarantee that hot water water level in heat collection water tank drops to the upper shed of each vacuum tube when following, the water tank bottom surplus hot water is extracted in each vacuum tube, thereby extract out by siphon pipe again, for people to use.Each short distance siphon pipe 7 can be metal also can be nonmetal bend pipe.The utility model can be located in the various sizes vacuum pipe solar water heater heat collection water tank, significantly improves its hot water use amount and the effective heat purpose that gets of unit are to reach.
