Progressive guide pipe

Abstract

The invention discloses a progressive guide pipe, belongs to the technical field of solar photo-thermal utilization, and particularly belongs to a wall-mounted solar heat collection device. The progressive guide pipe consists of a gathering and conveying pipe, a buffer pipe and a positioning pipe, and is characterized in that a sub-pipe of the gathering and conveying pipe is embedded into a clamping cavity of an all-glass heat collecting core, and a main pipe is connected with the buffer pipe; the other end of the buffer pipe is connected with the positioning pipe, the positioning pipe leads out a frame body of a heat-absorbing medium all-glass solar heat collecting plate, and the positioning pipe is fixed on the frame body. The progressive guide pipe can be combined with the all-glass heat collecting core of the heat absorbing medium all-glass solar heat collecting plate, and under the condition that the clamping cavity of the all-glass heat collecting core is very thin, medium circulation is not affected by utilizing the principle of multi-path collection; and moreover, the deformation coefficient is increased by utilizing the buffer pipe, and the vulnerability in the assemblingand transporting process is avoided.

Description

technical field [0001] The invention belongs to the technical field of solar light and heat utilization, in particular to a wall-mounted solar heat collecting device. Background technique [0002] Stand-alone solar water heaters occupy a large market share as the most energy-efficient household water heaters. Especially with the increasing number of high-rise buildings, balcony wall-mounted solar water heaters have gradually become the mainstream; the core technology of the current balcony wall-mounted solar water heaters is wall-mounted solar heat collectors, and wall-mounted solar heat collectors are mainly welded copper coils with coated heat collectors As a heat collecting core, the front is laid with textured glass, and the back is laid with an insulation layer; the heat transfer medium circulates in the coil, and the heat conduction medium transfers heat to the jacket of the pressure-bearing heat preservation water tank, and heats the water in the inner tank through th...

Problems solved by technology

According to the original design plan, both the medium inlet pipe and the medium outlet pipe use glass nozzles, which are formed on the all-glass heat collector at one time, but in actual operation, due to the thick nozzle and the thinner all-glass heat collector, The process is complicated; moreover, the medium inlet pipe and the medium outlet pipe are made of glass, which is easily damaged during the assembly process. Once damaged, the entire all-glass heat collector core will be scrapped
