Main body includes heat transfer zone and gas chamber, and gas chamber is arranged above heat transfer zone, and the heat exchanger tube is arranged in heat transfer zone and passes through gas chamber,
The heat exchanger tube includes tube body, spoiler and sleeve, and the spoiler is arranged in tube body one end, and sleeve is connect with tube body, flow-disturbing
Part is arranged between sleeve and tube body, and spoiler has a plurality of gas channel, and gas channel is parallel and interval is arranged, the tube body
Including the first air inlet and the second air inlet, the first air inlet is connected to gas channel, and second air inlet is arranged in tube body
Side, gas blow pipe one end are connected to the second air inlet, and the other end is connected to gas chamber.
It is the attached technical scheme of the utility model below.
Preferably, the sleeve is equipped with compressed part and accommodating chamber, accommodates inner cavity surface and is equipped with internal thread, described to disturb
Part is flowed to be arranged in accommodating chamber.
Preferably, the tube body end is equipped with external screw thread, and external screw thread is coupled with the internal thread.
Preferably, the gas blow pipe is obliquely installed, and the position of second air inlet is less than gas chamber.
The technique effect of the utility model：A kind of boiler phase-change heat-exchanger of the utility model can enhance changing for heat exchanger tube
