Tube type heat collector capable of efficiently collecting heat

Abstract

The invention relates to a tube type heat collector capable of efficiently collecting heat. The tube type heat collector capable of efficiently collecting the heat comprises a heat collector frame, a vacuum pipe, a U-shaped heat collecting pipe, a metal fin, a medium circulation inlet and outlet opening, a medium heat collecting inlet and a seal ring. The tube type heat collector capable of efficiently collecting the heat is characterized in that the vacuum pipe is installed inside the heat collector frame, the vacuum pipe is connected with the heat collector frame through the seal ring, the U-shaped heat collecting pipe is inserted into the vacuum pipe, the upper pipe body of the U-shaped heat collecting pipe is a heat collecting pipe body, the lower pipe body of the U-shaped heat collecting pipe is a heat collecting cooling pipe body, the metal fin is inserted into the heat collecting pipe body on the U-shaped heat collecting pipe, two end portions of the U-shaped heat collecting pipe are connected with a heat collecting outlet and a heat collecting inlet respectively, and the heat collecting outlet and the heat collecting inlet penetrate through the heat collector frame and are connected with the outer portion of the heat collector frame. The metal fin is additionally arranged, therefore, heat energy transmission efficiency is improved, and medium circulation speed and heat collecting efficiency are improved.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a high-efficiency heat-collecting tubular heat collector. Background technique [0002] The heat collection methods currently used are U-tube heat collectors, vacuum heat pipe heat collectors and flat plate heat collectors. U-shaped tube collectors have insufficient heat absorption due to the small external area of ​​the U-shaped tubes, which causes the heat in the vacuum tube to be lost and the overall heat collection efficiency is low; the heat collection efficiency of the vacuum heat pipe collector is high, but with the increase of the service life The vacuum gradually decreases, making the heat collection efficiency insufficient, and the damage of individual heat collection tubes will affect the operation of the entire collector; the flat plate heat loss is large and is not suitable for cold regions, and the overall thermal efficiency is not high.
