Embodiment Construction

[0015] Examples see figure 1 As shown, a double-metal channel solar vacuum heat collecting tube includes an ordinary glass vacuum heat collecting tube 1, and the ordinary glass vacuum heat collecting tube 1 is internally covered with a metal heat-conducting tube 2 communicating with a hot water inner tank, and the metal heat-conducting tube 2 It is a blind pipe, and its inner sleeve is a diversion pipe 3 connected with the cold water tank. The diversion pipe 3 is a metal pipe with two ends open, and hot water is reserved between the metal heat conduction pipe 2 and the diversion pipe 3 Passage 4, after the combination of the above three tubes, the axis coincides, and at the same time, the open end of the metal heat-conducting tube 2 is exposed from the guide tube 3, the ordinary glass vacuum heat-collecting tube 1 is inserted into the insulation layer of the double-liner header, and the metal heat-conducting tube The tube 2 exposes the open end of the ordinary glass vacuum hea...

Abstract

The invention relates to a double-metal channel solar vacuum heat collecting tube, in which a metal heat conducting tube is set inside an ordinary glass vacuum heat collecting tube, the metal heat conducting tube is a blind tube, and a flow guide tube is set inside it, and the flow guide tube is two ends An open metal tube, a hot water channel is reserved between the metal heat conduction tube and the flow guide tube, the axes of the above three tubes coincide after being combined, and at the same time, the open end of the metal heat conduction tube is exposed from the flow guide tube, and the metal heat conduction tube The tube exposes the open end of a common glass vacuum collector tube. By setting the metal heat pipe, the contact between water and the heat collecting pipe is avoided, which facilitates the replacement of the heat collecting pipe. At the same time, the setting of the guide pipe can separate the incoming cold water from the heated hot water, avoiding repeated heating of cold and hot mixed water, and improving the efficiency. Utilization of thermal energy. It can be widely used in solar headers.

Description

technical field [0001] The invention relates to a heat collecting tube, in particular to a vacuum heat collecting tube used in solar energy. Background technique [0002] Most of the heat collecting tubes used in the solar heat collectors used in my country are filled with water in the tubes, and the heat collecting tubes directly heat the water in the tubes, and then the heat is transferred to the water tank by the water in the tubes. Its advantages are fast heat collection and high heat collection efficiency, but its biggest disadvantage is that if any heat collection tube breaks, the entire heat collector will be paralyzed. Only drain the water from the heater, replace it with a new heating tube, and heat up. to restart the machine. This is very water-consuming and time-consuming. Contents of the invention [0003] The purpose of the present invention is to provide a kind of bimetal runner solar vacuum heat collecting tube, to solve the technical problem that the hea...
