Abstract

The utility model relates to a burble mixing heat exchange tube used on a chemical equipment heat exchanger; the heat exchange tube comprises a shell tube and a burble mixing part; the burble mixing part is arranged in the shell tube. The burble mixing part consists of a plurality of burble mixing units which are linked together; all burble mixing units rotate for 20 degrees to 40 degrees in the same direction from head to tail. Each burble mixing unit consists of a left fin, a right fin and a crossed rib; the lower end of the left fin and the lower end of the right fin are connected with a transverse sheet of the crossed rib; the angles between the left fin and a vertical sheet of the crossed rib and between the right fin and the vertical sheet of the crossed rib are 20 degrees to 40 degrees, one is forward (backward), and the other is backward (forward); the angles between the left fins of adjacent two burble mixing units and the vertical sheet of the crossed rib and between the right fins of the adjacent two burble mixing units and the vertical sheet of the crossed rib are the same but in the opposite directions; the burble mixing units of the burble mixing part are processed with the same plate. The heat exchange tube has the advantages that during work, the left fins and the right fins are slightly stretched in the shell tube and tightly adhered with the tube without any gap, to prevent laminar flow inner layer on the tube wall, so that the heat exchange efficiency is high.

Description

Flow-disturbing mixed heat transfer pipe

Affiliated technical field

The utility model relates to the heat exchanger tube of using in a kind of heat exchanger of chemical industry equipment

Technical background

The heat exchanger tube of using in the heat exchanger of chemical industry equipment has various ways at present, the simplest a kind of be hollow pipe, heating agent or refrigerant are in the outside of pipe, need the fluid of heat exchange in hollow pipe, to flow, reach the purpose of heat exchange, the weak point of this heat exchanger tube is: the fluid of heat exchange flows in pipe, flow velocity in the pipe is parabolic shape, heat exchanging fluid is in the flow velocity maximum at place, pipe axle center, press close to the flow velocity minimum at tube wall place, if high viscosity fluid carries out fluid interchange in pipe, the flow velocity of then pressing close to the tube wall place is near zero, caused tube wall near an almost immobilising viscous flow internal layer is arranged, cause very big thermal resistance to heat exchanging fluid, heat exchange efficiency is reduced greatly, be not suitable for the heat exchange of high viscosity fluid, the patent No. is ZL200420027397.5 " high viscosity fluid high-performance heat exchanger " patent, though in hollow pipe, loaded onto heat exchange element, but this heat exchange element is a matched in clearance with cooperating of pipe, certain clearance is arranged, still have an almost immobilising viscous flow internal layer at this gap location, only should the viscous flow internal layer a little thin than hollow pipe, still cause bigger thermal resistance to heat exchanging fluid, its heat exchange efficiency is still undesirable.

The utility model content

The purpose of this utility model is the weak point that overcomes the heat exchanger tube of at present used hollow heat exchanger tube and dress heat exchange element, and a kind of high flow-disturbing mixed heat transfer pipe of heat exchange efficiency that the flow-disturbing mixer element is housed in pipe is provided.

The purpose of this utility model is achieved through the following technical solutions.Flow-disturbing mixed heat transfer pipe is made up of package and flow-disturbing mixer element, in the flow-disturbing mixer element dress package, the flow-disturbing mixer element is linked by a plurality of flow-disturbing mixed cells and forms, and each flow-disturbing mixed cell is from first to last to 20～40 ° of same direction (simultaneously to clockwise or simultaneously to counterclockwise) rotations.The flow-disturbing mixed cell is made up of left fin, right fin and cross muscle sheet, the left side fin and the lower end of right fin and the transverse sheet of cross muscle sheet link, the angle of the riser of left side fin and right fin and cross muscle sheet is respectively 20～40 °, and a slice is (back) forward, and another sheet is (preceding) backward.The corner dimension of the left fin of adjacent two flow-disturbing mixed cells, right fin and the riser of cross muscle sheet is identical but direction angle is opposite.A plurality of flow-disturbing mixed cells on the flow-disturbing mixer element are to be processed into and on same axis with same sheet material.

The heat exchanger tube that heat exchange element is housed in the utility model and at present used hollow heat exchanger tube and the pipe is compared, left side fin and right fin have opening of a small amount of when having work in package, make the tube wall of flow-disturbing mixer element and package be adjacent to no gap, make the tube wall place not have the viscous flow internal layer and the heat exchange efficiency height, or in a small amount gathering arranged, each flow-disturbing mixed cell can be packed in the package at an easy rate, the advantage of can be at an easy rate during cleaning releasing in the package.When fluid flows in package 1, run into left fin 3 and right fin 4 on the flow-disturbing mixer element 2, make the direction of flow pipe central authorities at tube wall place, the direction of flow tube wall place of pipe central authorities, all there is ripple fluidised form radially uniformly at each place, unit, the thermal resistance that this flow-disturbing mixes when it is conducted heat reduces significantly, and heat exchange efficiency is improved greatly.

Description of drawings

Accompanying drawing 1 structural representation that to be flow-disturbing sub-assembly some of the present utility model extract out in the package, Fig. 2 is the left view of Fig. 1, and Fig. 3 is each flow-disturbing mixed cell of flow-disturbing mixer element structural representation when not reversing, and Fig. 4 is the left view of Fig. 3.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.In the accompanying drawing: 1---package; 2---the flow-disturbing mixer element; 3---left fin; 4---right fin; 5---cross muscle sheet transverse sheet; 6---cross muscle sheet riser.When implementing, package 1 can be made of tubing, flow-disturbing mixer element 2 can be used board making, become the strip of thin-and-long according to the internal diameter blanking of package, then the strip boards of thin-and-long is packed into and strike out shape shown in Fig. 1 (Fig. 2) in the punch die, then with the flow-disturbing mixer element that does not reverse of drawing with the transverse sheet of the cross muscle sheet of the adjacent flow-disturbing mixed cell of clamp clamps successively clockwise (counterclockwise) reverse 20～40 °, with pack into the upper end of package 1, the lower end of reversing the flow-disturbing mixer element 2 of shaping, with the lower end of clamp clamps flow-disturbing mixer element 2, flow-disturbing mixer element 2 drawn in the package 1.The fluid that need carry out heat exchange during use flows into from upper end of the present utility model, and the outside of package 1 is heat (cold) matchmaker, can carry out heat exchange.
