Pipe tail low heat loss medium transfer sun vacuum energy changing hot pipe

Abstract

The invention discloses a tail pipe low heat loss agent conductance solar vacuum energy changing hot pipe, which is characterized by the following: comprising small diameter inner glass pipe and high diameter outer glass pipe; closing one end of pipe heat with glass weld; setting the outer surface as conversion energy film board; arranging discharge pipe sealing spout on the welded head of the big diameter outer glass pipe; locating mutually of sealing head same end; welding and closing the other end with glass cup shape; arranging glass located pipe sprout at the pipe head of the glass cup shaped welding position; arranging screw thread or fastening tank on the glass locating pipe sprout; arranging hot pipe in heat changing inner glass pipe; filling heat conducting medium between the heat changing inner glass pipe and the hot pipe; closing the hot pipe through closed end lid; connecting to the glass locating pipe sprout of the solar vacuum heat changing hot pipe; arranging heat-proofdevice at the rear end of the solar vacuum energy changing hot pipe; decreasing the loss of heat; arranging the heat-proof device in the small pipe diameter inner glass rear pipe; or arranging out ofthe small pipe diameter inner glass rear pipe. This invention can be used to solar energy application domain.

Description

technical field [0001] The invention relates to a low heat loss medium conduction solar vacuum energy conversion heat pipe at the end of the pipe, which belongs to the field of solar energy application. Background technique [0002] Due to its structural characteristics, the current all-glass solar vacuum heat collection tube cannot operate under pressure, and the steel at the end of the tube is severely heat-dissipated, while the glass-metal heat pipe has different expansion coefficients between glass and metal, and long-term operation will expand with heat and contract with cold, causing metal fatigue. There is a vacuum leak problem. The double vacuum glass heat pipe is not safe enough due to the small pressure bearing capacity of the glass, and the heat loss at the end is serious, especially in solar energy engineering. Once a single pipe bursts, the entire system will be paralyzed. The pressure-bearing operation of the system cannot be satisfied, and the solar vacuum he...
