Embodiment 1

[0042] Embodiment 1: A leakage-proof pressure-bearing solar collector with holes on one side. See figure 1 , image 3 .

[0043] The so-called single-sided opening means that all liquid ports are opened on one side of the pressure-bearing header.

[0044] The inner tank wall 1 of the pressure-bearing header has several reinforcing ribs 10, and several liquid openings 2 on one side, and the liquid openings 2 have external thread buckles; both ends are connected with inlet (outlet) liquid pipes 3 .

[0045] The open end 7 of the metal heat collecting tube 6 has an internal thread buckle, which is matched with the external thread of the liquid port 2 .

[0046] The heat-resistant sealing gasket 9 of the root of the liquid port 2. After the open end 7 of the metal heat collecting tube 6 is screwed onto the liquid port 2, the sealing purpose is achieved by extruding the heat-resistant sealing gasket 9.

[0047] 8 glass vacuum insulation tubes are set on the outside of the met...

Embodiment 2

[0050] Embodiment 2: A leakage-proof pressure-bearing solar collector with holes on both sides. See image 3 , figure 2 .

[0051] The so-called double-sided opening means that the liquid opening is opened on both sides of the pressure-bearing header, and there is a pressure-bearing inner tank 1 and a pair of inlet (outlet) liquid pipes 3.

[0052] The connection mode between the metal heat collecting tube 6 and the pressure header is the same as in Embodiment 1;

[0053] And the connection mode of glass vacuum insulation pipe 8 and pressure header is the same as embodiment 1;

[0054] Solar heat collection mode is the same as embodiment 1.

Abstract

The invention discloses a liquid-leakage preventing and bearing type solar heat collector, which is formed by the combination of a belt bearing union collection box, a plurality of metal heat collecting pipes and a plurality of glass vacuum insulating pipes. A bearing inner container is provided with a container wall reinforcing bar, a liquid inlet, a liquid outlet and a plurality of liquid-passing ports; the opening end of the metal heat collecting pipe is hermetically connected with the liquid-passing ports of the bearing union collection box through screw threads or other ways; and the glass vacuum insulating pipe is a transparent glass vacuum pipe which is sleeved outside the metal heat collecting pipe and is inserted into an insulating layer of the bearing union collection box.

Description

technical field [0001] The invention relates to a leakage-proof pressure-bearing solar heat collector. Specifically, the traditional vacuum tube solar heat collector is improved, and metal heat collecting tubes are used to collect heat, and glass vacuum insulation pipes are used to prevent heat loss. Change to a pressure-bearing type to achieve high-efficiency heat collection, system pressure and prevent leakage. This solar heat collector can be applied to large-scale or super-large solar heat collection systems, and can also be used in specific solar high-temperature heat collection systems. Background technique [0002] With the advancement of solar thermal utilization technology, the photothermal market is getting bigger and bigger, and the technology is becoming more and more mature. The more mature products include vacuum tube collectors, heat pipe collectors and flat panel collectors, but in market applications, There are also some problems, such as: [0003] (1) Eva...
