In the vacuum heat industry, air-cooling vacuum furnace has obtained application more and more widely.Circulation and two kinds of structures of outer circulation in air-cooling vacuum furnace is divided into by the air-flow endless form.In the internal-circulation type air-cooling vacuum furnace, air-flow and heat exchanger because of exist the temperature difference with heat conducting mode by air-flow with the heat transferred heat exchanger, the characteristics of this mode are exactly that both contacts area are big more, the efficient of transmission is high more.But existing heat exchanger is a square structure, because of fault of construction makes the heat exchanger surface area to be utilized effectively, causes heat transference efficiency not high, and heat exchange effect is not ideal enough.
Summary of the invention
The present invention is directed to the problems referred to above, provide the air-cooling vacuum furnace that a kind of heat exchange area is big, heat exchange efficiency is high to use heat exchanger.
According to technical scheme of the present invention: a kind of air-cooling vacuum furnace is used heat exchanger; Comprise water tank and heat exchanger tube; Said water tank is fixed between the bleeding point deep bead of circular preceding deep bead and circle, and is positioned at the said circle outside radially, and the center of said bleeding point deep bead has bleeding point; Said heat exchanger tube is arranged between said preceding deep bead and the said bleeding point deep bead; And be positioned at the outside of said water tank; Said heat exchanger tube be connected between two sidewalls of said water tank, with many circles ring tube of the concentric setting of said bleeding point; The said ring tube of every circle comprises the ring tube that multilayer is identical, and the center of the said heat exchanger tube of inner ring constitutes air collecting chamber.
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.
Technique effect of the present invention is: heat exchanger of the present invention 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.
