Adopt the spiral spring support turbulence structure equally spaced be installed between the heat exchanger tube and with the heat exchanger tube close contact, support heat exchanger tube in the multi-point support mode, the supporter voidage is high between pipe, disturbance and the confusion of shell fluid have effectively been increased, attenuate the thickness in boundary layer, the resistance of convection cell is little, has improved heat transfer efficiency.Pipe side liquid entrance, the outlet of pipe side liquid and heat exchanger tube consist of the tube side runner, and shell fluid entrance, shell fluid export the shell fluid passage that jointly consists of heat exchanger with spiral spring supporting construction.
Described exchanger head bobbin carriage is made of exchanger head, dividing plate and the first tube sheet, and exchanger head bobbin carriage and dividing plate are welded into one, and dividing plate is horizontally placed between exchanger head and the first tube sheet.The inside and outside advection heat of enhanced tube changes, and improves Composite Walls, improves the heat transfer property of whole heat exchanger.Spiral spring supporter can be the Si-Mn steel or stainless steel, also can pass through the method manufacturings such as continuous casting, die casting by other high strength or corrosion-resistant material.
It is gradually-reducing-expanding type spiral spring that described spiral spring supports turbulence structure.Gradually-reducing-expanding type spiral spring structure rigidity is larger, can bear than heavy load, and flat segments is supporting construction, and the convergent divergent segment is turbulence structure, and supporter is according to the tubular layout of heat exchanger tube, and supporting section is selected suitable pitch.
Described spiral spring supports turbulence structure and is connected with heat exchanger tube with a way of contact.Attenuate the thickness in boundary layer, improve heat transfer efficiency.
Described heat exchanger tube can be taken over for light pipe, shaped telescopic tube, band bellows, helical bellows, twisted tube spiral grooved tube or ripple.
The connected mode of described heat exchanger tube and the first tube sheet and the second tube sheet is intensity weldering or intensity expanded joint.Strengthen fastness.
The connected mode of described convex head and the second tube sheet is built-up welding, and built-up welding thickness is 4mm-6mm, and convex head is connected with housing by flange arrangement.
The beneficial effect that the utility model has is: the shell and tube exchanger that described spiral spring supports heat exchanger tube utilizes special spiral spring formula structure as the high characteristics of supporter voidage between pipe, the disturbance that can effectively increase shell fluid with mix, attenuate the thickness in boundary layer, and the resistance of himself convection cell is very little, has improved the efficient of conducting heat.In addition, replace existing smooth heat transfer tube with special pipe, but enhanced tube inside and outside heat convection, improve Composite Walls, improve the heat transfer property of whole heat exchanger.Compared with prior art, in the constant situation of heat transfer technique, this method for designing can be saved the consumption of metal material greatly, reduces and makes production cost, and energy savings consumption has considerable economic benefit and social benefit in today of energy worsening shortages.
