Corrugated tube heat exchanger

High heat transfer coefficient The enhancing of heat transfer of Corrugated Tube Heat Exchanger depends on its unique heat transfer element—corrugated tube. The corrugated tube is a thin-wall tube formed by tangent circle arc connected with each other in the shape of wave. The radius of the circle arc and the pitch of the corrugation are produced following specific design. Because of the continuous changing of the cross section of pipe, the heat transfer coefficient is two or three times of that of conventional shell and tube heat exchanger. Small flow resistance As the improving of heat transfer ability mainly depends on the breaking up of liquid boundary layer by the field energy, the flow speed is not very high. When the transferred heat quantity is same, the flow resistance of this type of heat exchanger is smaller than that of other types, thus has a distinct energy conservation effect. Hard to scale on the surface of heat transfer element During operation, the corrugated tube, with the influence of difference of medium’s temperature, will have a little axial extension and frequent change in the curvity inside and outside the pipe. Because the coefficients of linear thermal expansion of scale layer and corrugated pipe are differ greatly, under the effect of differential temperature, between scale and pipe a pull-out force will be generated strong enough to drop the scale off. As for heat supplying and air conditioning system, this advantage can ensure a continuous operation. Keep the high temperature and high pressure resistance features as in conventional tubular exchanger. With the ability of self-compensation for heat stress The special structure of corrugated tube makes it flexible under high temperature so as to compensate the heat stress and prolong the equipment’s service life.
