Abstract
The utility model relates to a metal flow passage matched with a glass solar collecting tube, which serves an upper flow passage and a lower flow passage as the main body, and a seal cavity room is respectively matched with lower end openings of upper flow passage and the lower flow passage. The seal cavity room effectively increases the flowing space at the connecting position of the lower end openings of the upper flow passage and the lower flow passage, and thus, the flow rate of the transmitting medium in the tube is increased, and the temperature rise is fast, which increase the integral heat-transfer efficiency of the transmitting medium, and simultaneously the flowing space at the connecting position of the lower end openings of the upper flow passage and the lower flow passage is enlarged, which can effectively prevent the blocking phenomenon at the position happening and extend the usage time of free maintenance for a solar energy water heater.
Description
The utility model relates to a kind of and the matching used metal flow passage of glass solar heat collection pipe.
The metal flow passage that is used for glass solar heat collection pipe at present mostly adopts " U " type tubular construction that is made of upper runner, and this kind structure makes the heat transfer substance flow resistance in its pipe big because the runner of " U " type pipe bottom is narrower and small, has a strong impact on its heat transfer efficiency." U " type pipe bottom scaliness very easily can make pipeline blockage when serious simultaneously, causes the overall thermal hydrophone out of service.
The purpose of this utility model is to provide a kind of conductivity of heat height, the glass solar heat collection pipe metal flow passage of long service life.
The purpose of this utility model is achieved in that its above lower flow channel is a main body, connects a sealing chamber in the lower port of last lower flow channel.
In order to improve the heat absorption capacity of runner, equipped heat absorption fin on upper runner.
The technological progress that the utility model is obtained: the chamber that installs a sealing in the lower port of last lower flow channel additional, enlarged the flowing space of last lower flow channel lower port junction effectively, thereby the flow velocity of transmitting medium increases in the pipe, and temperature rise speed is fast, improves its whole heat transfer efficiency.This place also is difficult for stopping up simultaneously, can prolong the freedom from repairs service time of overall thermal hydrophone effectively.This utility model can be widely used in the solar water heater of drowning formula or pressure-bearing top ability of swimming structure.
Be that embodiment further describes the utility model below with the accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of another embodiment of the utility model.
As shown in Figure 1, lower flow channel 1,2 parallel arranged on two, the two leaves the space, and its two lower port is affixed sealing chamber 3 respectively.In order to improve the heat absorption capacity of runner, make up and down and produce the temperature difference between two runners, on upper runner 2, be fitted with the heat absorption fin, and do not adorn the heat absorption fin on the lower flow channel.The upper port that goes up lower flow channel 1,2 during use is inserted in the storage tank of solar water heater, and last lower flow channel 1,2 and sealing chamber 3 constitute a peripheral passage with storage tank.
Fig. 2 is another embodiment of the present utility model, is that with above-mentioned difference lower flow channel 1,2 selects the disjunctor pipe for use, and installs the heat absorption fin additional on a sidewall of upper runner 2, also can finish above-mentioned functions.
Claims (2)
1, a kind of glass solar heat collection pipe metal flow passage, its above lower flow channel is a main body, it is characterized in that the lower port of lower flow channel connects a sealing chamber.
2, the effective metal flow passage of solar energy heating according to claim 1 is characterized in that equipped heat absorption fin on the upper runner.
