Abstract
The utility model relates to the field of solar energy utilization, and particularly discloses a solar vacuum heat collecting middle pipe, which comprises a transparent outer pipe, an inner pipe and a fixing clamp, wherein a black film is coated on the outer wall of the inner pipe, and the fixing clamp is arranged between the outer pipe and the inner pipe. The solar vacuum heat collecting middle pipe is characterized in that the tail end of the inner pipe is recessed inwards to form an extending pipe, a gap is reserved between the pipe walls of the extending pipe and the inner pipe, and vacuum is arranged between the outer pipe and the inner pipe. The solar vacuum heat collecting middle pipe has the advantages of simple structure, convenient utilization, reasonable design, capabilities of effectively increasing sunlight absorption area and improving heat conduction efficiency, and suitability for popularization and application.
Description
(1) technical field
The utility model relates to field of solar energy utilization, manages in particularly a kind of solar vacuum heat-collecting pipe.
(2) background technology
Solar energy Transform Sets heat pipe is one of core technology of solar water heater.Existing vacuum heat collection pipe is that an a kind of end is uncovered, the double-layer glass tube of end sealing, the inner tube outer surface coated black film of glass tube, the space sealing vacuum of inside and outside layer pipe; Blind end is positioned in the bottom bracket hole, and open-mouth section inserts in the storage tank by sealing ring, and the water in the thermal-collecting tube reaches the purpose of heating with the cold water convection current of storage tank behind the solar radiation heat temperature raising.
Because the contact area of the water of vacuum heat collection pipe inside and tube wall is limited, under or the state that current are too fast bad at sunlight, the heat transmission function of vacuum heat collection pipe is limited, and the heated efficient of water is very low.
(3) summary of the invention
The utility model provides in a kind of solar vacuum heat-collecting pipe simple in structure, easy to use and has managed in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Manage in a kind of solar vacuum heat-collecting pipe, comprise the interior pipe of transparent outer tube, outer wall coated black film and the fixedly card between outer tube and interior pipe, it is characterized in that: the pipe end formation extension that caves inward in described, have between the tube wall of extension and interior pipe at interval, be vacuum between outer tube and interior pipe.
The utility model is at water and the limited shortcoming of tube wall contact-making surface in the existing vacuum heat collection pipe, pipe in it is improved, and the area of the interior pipe of increase reduces the capacity of water in the vacuum heat collection pipe, and then the contact area of increase water and inner pipe wall, improve its efficiency of heating surface.
More excellent scheme of the present utility model is:
In order to keep the vacuum in the vacuum heat collection pipe, on the fixedly card between outer tube and interior pipe, getter is set.
In order to guarantee the stability of extension and interior pipe, strengthen its bearing capacity, fixing card is set between extension and interior pipe, prolong its service life.
Because the water capacity in the vacuum heat collection pipe reduces, for being fit to resident's daily user demand, the outer tube caliber is set at 70mm, corresponding inner tube diameter is set at 58mm, and the extension caliber is set at 47mm.
The utility model is simple in structure, and is easy to use, reasonable in design, can effectively increase to absorb the sunshine area, improves heat transfer efficiency, is suitable for applying.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 outer tube, 2 interior pipes, 3 fixing cards, 4 extensions, 5 getters.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises the fixedly card 3 of 2 of the interior pipe 2 of transparent outer tube 1, outer wall coated black film and outer tube 1 and interior pipes, described in pipe 2 ends cave inward and form extension 4, have between the tube wall of extension 4 and interior pipe 2 at interval, 2 of outer tube 1 and interior pipes are vacuum; The fixedly card 3 that described outer tube 1 and interior pipe are 2 is provided with getter 5; 2 of described extension 4 and interior pipes are provided with fixing card 3; Described outer tube 1 caliber is 70mm; Pipe 2 calibers are 58mm in described, and extension 4 calibers are 47mm.
Under the solar radiation, interior pipe 2 absorbs heats, the vacuum zone temperature of 2 of outer tube 1 and interior pipes is raise, be connected with cold water in the space that interior pipe 2 inwalls form, cold water contacts with interior pipe 2 tube walls and carries out heat exchange and be heated, cold water in heated hot water and the solar storage water tank forms convection current, thereby reaches the purpose of heat exchange.
Claims (5)
