Embodiment 1

[0028] Such as figure 1 , figure 2 The flow path of the pressure-bearing glass heat pipe solar heat collector shown includes the inlet water nozzle 1, the first branch flow channel 2, the second branch flow channel 3 and the outlet water nozzle 6 connected in sequence; the two branch flow channels are wave Shaped metal flow channel, the inner side of the crest is in close contact with the outer side of a heat conduction ring 4; the heat conduction ring 4 is provided with a narrow gap 5. The condensing end of the glass heat pipe is inserted into the heat conduction ring 4 and tightly fitted with the inner side of the heat conduction ring.

[0029] The working process of this embodiment is: the glass heat pipe transfers the heat converted from solar energy to the heat conduction ring 4, and the heat conduction ring 4 transfers the heat to the first branch channel 2 and the second branch channel 3, and the inlet water The fluid entering the wave-shaped flow channel through the...

Abstract

The invention discloses a pressure-bearing type glass heat pipe solar heat collector runner and a heat collector. The pressure-bearing type glass heat pipe solar heat collector runner comprises an inlet water nozzle, a waveform runner and an outlet water nozzle which are connected in sequence, wherein the inner side of the wave crest of the waveform runner is in tight contact with the outer side of a heat conduction ring; a condensed end of a glass heat pipe is inserted into the heat conduction ring and is in tight fit with the inner side of the heat conduction ring; the pressure-bearing type glass heat pipe solar heat collector adopts the heat collector runner. By adopting the pressure-bearing type glass heat pipe solar heat collector runner, the pressure-bearing capability of the pressure-bearing type glass heat pipe solar heat collector runner is greatly improved; the heat transferring speed of the glass heat pipe is improved to some extent; the heat conduction ring can guarantee that the glass heat pipe is not broken when the heat collector is assembled.

Description

technical field [0001] The invention relates to a flow path and a heat collector of a pressure-bearing glass heat pipe solar heat collector. Background technique [0002] Most of the current heat pipe vacuum tube collectors are non-pressurized collectors, and the flow channel of the collector is generally in-line, that is, the condensing end of the glass heat pipe is directly inserted into the flow channel of the header, and directly exchanges heat with the medium in the flow channel. , The connection between the glass heat pipe and the flow channel is sealed by a rubber ring. But this kind of flow path is not suitable for pressure-bearing heat collectors, because when the fluid pressure is high, the connection is easy to leak, and the safe operation of the heat collector cannot be guaranteed. And because the glass is a fragile product, the glass heat pipe is easy to break when it is closely matched with this flow channel, so the heat collector is very difficult to assemble...
