Connecting structure of evacuated solar heat pipe with sealing filler and inner fin-typed manifolder with silicon ring

摘要

The present invention provides a connection structure between a heat pipe and a manifold, which is used in a vacuum tube heat pipe solar collector, that is, between two apparatuses for carrying out the transfer of accumulated solar energy starting through the manifold in the condensation portion of the heat pipe without heat loss. Of the connection structure.;Heat pipe of the vacuum tube solar collector of the present invention is inserted into the connector of the manifold to be bolt-nut coupling, the predetermined length of the outer circumferential surface of the end portion of the heat pipe manifold connection side is helically processed, passing through the spiral processing portion of the heat pipe Filler with a disk-like layered structure, such as overlapping two disks of different diameters, centered on the outer circumferential surface of the heat pipe at a distance corresponding to the depth of the manifold connector from the end of the connection side. It is composed of a structure.;The filler is a two-layer structure in which one layer is in close contact with the silicon ring in the manifold connector and the other layer is firmly attached by welding or the like around the connector inlet to seal the connection portion between the heat pipe and the manifold.;In addition, the manifold of the present invention also has a cylindrical connector inner circumferential surface is a layered structure, a coiled fin that can be coupled to the spiral outer circumferential surface of the heat pipe is attached to the lower inner circumferential surface of the small diameter, the coiled pin is coupled to the heat pipe In addition to the role, the contact area between the two devices is increased to allow efficient heat transfer at the interface between the two devices.;In addition, a silicon ring is seated on the jaw portion where the inner diameter of the large diameter and the inner diameter of the small diameter meet with the inlet side of the manifold connector to be in close contact with the filler surface of the heat pipe, thereby providing a primary seal.;Therefore, in the present invention, the heat transfer between the heat pipe and the manifold is made very efficient by the sealing by the silicone ring, the sealing around the connector by the filler, and the increase in the heat transfer area by the coiled fins.
