Abstract
The utility model relates to a circulation type solar heat collecting pipe, which belongs to an utilization device of solar energy heat. Because the utility model adopts the purpose-made vacuum heat collecting pipe and a water cycle communication device, a water cycle speed is enhanced. Heat transfer is accelerated. Meanwhile, scale deposits in the vacuum heat collecting pipe can be easily removed by chemical methods if the utility model is adopted. The circulation type solar heat collecting pipe has the advantages of work efficiency enhancement and extension of the service life of the vacuum heat collecting pipe.
Description
The utility model relates to application of solar, particularly relates to solar energy heat collector.
At present, in utilizing the heat collector of solar energy, more employing solar energy vacuum tube thermal-arrest mode, as Chinese utility model patent CN2124434U, a kind of focus type vacuum tube solar heating element is disclosed, it is made up of vacuum tube and reflecting condensation cylinder, water is heated in the convection circulation in water tank and vacuum heat collection pipe, but at present in the middle of the mode of the vacuum tube that adopts to the water heating, following shortcomings of ubiquity all: 1. since vacuum tube one end seal, influenced the circulation rate of water, the thermal efficiency is not high.2. because the circulation rate of water is slow, incrustation scale is accumulated on the vacuum tube inwall, use mostly that the thermal efficiency reduces greatly after 1 year.3. the work difficulty of removing vacuum tube inwall incrustation scale is big, because sealing of vacuum tube, water can not flow in the pipe, can not use the cleaning agent scale removal, can only use the mechanical means scale removal, and incrustation scale is difficult for cleaning out.Since in the winter vacuum tube residual water be difficult for emptying, the easy bursting by freezing of vacuum tube.
The purpose of this utility model is that it is main mode that the deficiency at above-mentioned technology provides the special solar vacuum heat-collecting pipe of a kind of employing, and the circulation rate that can accelerate water is easy to the solar energy vacuum tube water heater of scale removal.
The purpose of this utility model is achieved in that employing solar vacuum heat-collecting pipe special, the equal opening in two ends (1), and the top of thermal-collecting tube (1) connects water storage tank (3), and the bottom connects circulating water flow linker (4).Thermal-collecting tube (1), water storage tank (3) and circulating water flow linker (4) are connected in aggregates by support (5).In order to improve solar energy utilization ratio, prevent heat abstraction, also can adopt heat collector with thermal-collecting tube (1) and recirculated water linker (4) encapsulation.
Because the utility model has adopted the solar energy heat collection pipe (1) and the circulating water flow linker (4) of special both ends open, improved water circulating speed, be easy to remove incrustation scale with chemical method, improved the utilization ratio of solar energy, residual water in easy emptying pipe during winter, unlikely pipe bursting by freezing has prolonged service life of vacuum heat collection pipe.
Fig. 1 is vertical cut-away view of solar vacuum heat-collecting pipe special in a kind of circulating type solar energy heat collector of the utility model.
Fig. 2 is the structural representation of a kind of circulating type solar energy heat collector of the utility model.
Fig. 3 is the different embodiment schematic diagrames of the water circulation linker of a kind of circulating type solar energy heat collector of the utility model.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
Select the solar energy heat collection pipe (1) of several special both ends opens for use, thermal-collecting tube top is inserted in the water storage tank (3), and the bottom of thermal-collecting tube is inserted in the square tube shape water circulation linker (4), is attached thereto in aggregates by support (5).Behind water inlet pipe (6) water-filling, because absorbing the solar heat of transmitting between each thermal-collecting tube is not quite similar, cause the interior water temperature of each thermal-collecting tube inconsistent, again because the lower end of thermal-collecting tube communicates with water circulation linker, promoted between thermal-collecting tube and thermal-collecting tube, the circulation and the heat transmission of the water between thermal-collecting tube and the water storage tank.By outlet pipe (7) output hot water.When in the thermal-collecting tube during incrustation, removable thermal-collecting tube down adopts chemical method, removes with the cleaning fluid spary.
As further improvement of the utility model, between water circulation linker (4) and water storage tank, inserted a communicating pipe (8) that promotes the water ringing, like this, during incrustation scale in removing thermal-collecting tube, needn't pull down thermal-collecting tube, cleaning fluid can be squeezed into communicating pipe in (8) and directly be cleaned.
As another kind of improvement the of the present utility model, water inlet pipe (6) can be moved on water circulation linker (4), can directly cleaning fluid be removed the interior incrustation scale of thermal-collecting tube by water inlet pipe (6).Simultaneously, when winter, be easier to the residual water in the emptying vacuum tube, prolonged the service life of vacuum tube.
The utility model is not limited to above embodiment, and water circulation linker also can be made other multiple style, as trapezoidal tube etc., all falls within the utility model protection domain.
Claims (3)
1, a kind of circulating type solar energy heat collector is made up of vacuum tube, water storage tank, support, water circulation linker and inlet tube and outlet tube, it is characterized in that the equal opening in described vacuum heat collection pipe two ends.
2, solar thermal collector according to claim 1 is characterized in that, is connected to water circulation linker in the lower end of vacuum heat collection pipe.
