Each layer ring tube of the adjacent said heat exchanger tube of two circles is crisscross arranged.
The cross section of said water tank is an isosceles trapezoid, and two waists of said isosceles trapezoid are through the center of circle of said circle.
Be equipped with a plurality of sleeve pipes between the circumference of deep bead and said bleeding point deep bead before said, be penetrated with the bolt that stretches out said preceding deep bead and said bleeding point deep bead in each said sleeve pipe, the two ends of said bolt are fastened with nut.
Be fixed with the flange base on the water inlet of said water tank and the delivery port respectively, be equipped with lap joint flange on each said flange base.
Said heat exchanger is provided with mount pad, and said mount pad is fixed on said preceding deep bead and the said bleeding point deep bead.
The technique effect of the utility model is: the heat exchanger of the utility model is for circular, and the design of the many circles of heat exchanger tube employing multilayer ring tube, helps utilizing furnace inner space, and heat exchange area increases greatly, and exchange capability of heat has obtained reinforcement, and heat exchange efficiency is high.
