Embodiment Construction
[0016] figure 1 and figure 2 An embodiment of the present invention is collectively given. figure 1 and figure 2 Among them, the inner glass-finned plate tube 1 is connected with the barges 3 on both sides of the header box 2 with sealing rings to form a horizontal vacuum inner glass-finned plate tube solar steam generating device. The inner glass-fin plate tube 1 is arranged horizontally; the union box 2 has a casing and heat insulating material, and its axis line has a horizontal inclination angle to ensure that the light-concentrating reflector track changes in the sun's altitude angle. For the sake of brevity, the light concentrating reflector is not shown in the figure. Two multi-valve linkage electric group valves, the high group valve 4 and the low group valve 5, are used. Each valve of electric group valve 4,5 is installed on each dam 6 of multi-level cascade dam respectively, and can be opened and closed synchronously by being connected with link rod 7,8 that is...

The invention provides a solar heat collecting device having an internal glass tube with a finned plate. The device is composed of an internal glass tube with a finned plate and a union box, and is characterized in that the internal glass tube with a finned plate is installed horizontally; through adjusting the state of a heat collecting pipe and arranging water retaining objects in the union boxor the pipe orifice of the heat collecting pipe, water can be retained when flowing out of the heat collecting pipe and gas can be retained through arranging the water retaining objects on the upper part of the heat collecting pipe orifice when water flows in the heat collecting pipe. The invention has the following beneficial effects: the internal glass tube with a finned plate is arranged horizontally and a vapor-water two phase flow heat transfer circulation can be realized in the interior of the tube, thus the heat-transfer capability is strong; water retained in the heat collecting pipe can prevent the empty pipe from sunning and avoid the pipe burst caused by suddenly entered cold water; and the internal glass tube with a finned plate utilizes an internal glass tube and a metal layer outside the internal glass tube to transfer heat directly from a heated region to a water-remaining region instead of using a wicking type material for carrying water, thus the scaling problem of the wicking type material can be avoided. The device provided by the invention has a simple structure and no moving parts in the heat transfer link, is energy-saving and frost-resisting, has high reliability and can output water vapor with the temperature above 100 DEG C and large enough pressure. The invention provides an embodiment combined with a drawing.
Description
technical field [0001] The invention relates to a solar heat collecting device of an inner glass-fin plate tube. Background technique [0002] The existing vacuum heat collecting tube has high heat collecting temperature, small heat loss, and high degree of industrialization, and the intubated water heater manufactured with it can provide domestic hot water above 50°C in winter. But in general, the application products of vacuum heat collecting tubes are not rich and developed enough. Contents of the invention [0003] The object of the present invention is to provide a solar heat collecting device with an inner glass-fin plate tube. [0004] The technical solution adopted by the present invention to solve the technical problem is to use the inner glass-finned tube and the union box matched and connected with the inner glass-finned tube to form an inner glass-finned tube solar heat collection device. The inner glass tube of the inner glass-finned tube has metal fins, an...
