Description
Technical field
The utility model relates generally to a kind of arrangement of heat exchanger tube, relates in particular to a kind of pipe heat exchanger.
Background technology
In recent years, along with the rise of material cost, pipe with small pipe diameter copper pipe heat exchanger has the huge advantage of material cost.Suppose caliber to be decreased to 4mm by 7mm, the surface area of unit pipe range copper pipe will reduce 46.1%.This behave means, even if copper pipe thickness is constant, the copper consumption of unit pipe range reduces 46.1%.In fact, because the attenuation of copper pipe wall thickness, compressive resistance increase, the copper material consumption of unit pipe range can reduce more.Therefore,, if pipe with small pipe diameter heat exchanger tube can be applied to heat exchanger, can significantly reduce material consumption.After but the heat exchange caliber of heat exchanger reduces, need to increase heat exchanger tube and prop up the drag losses that way reduces to manage interior sharp increase, and too much heat exchanger tube props up way, can cause the fluid that flows to each heat exchanger tube how much to differ, make the degradation of heat exchange performance of heat exchanger.In order to address this problem, the utility model has proposed a kind of new version for this heat exchanger.
Utility model content
The utility model will solve to such an extent that technical problem is for above-mentioned the deficiencies in the prior art, and a kind of balance heat exchanger tube inner fluid flow and fluid resistance are provided, thereby improves the pipe heat exchanger based on pipe with small pipe diameter heat exchanger tube of heat exchange property.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of pipe heat exchanger, comprise housing and be arranged on the heat exchanger tube in housing, it is characterized in that: in described housing, be also provided with at least two-layer dividing plate, in described housing, by described dividing plate, be divided into the runner of the one-tenth S shape of at least three layers, entrance at the superiors' runner is provided with shell-side outlet, outlet at orlop runner is provided with shell-side inlet pipe, in the upper end of described housing, be provided with pipe side separating liquid pipe, in the lower end of described housing, be provided with pipe side collector tube, at described pipe side separating liquid pipe and pipe side collector tube, in axial direction go up the set of heat exchange tubes that at least two rows arrange along described runner that is provided with at interval, described every row's set of heat exchange tubes comprises and is arranged on described pipe side separating liquid pipe and pipe side collector tube axial direction same position and becomes two described heat exchanger tubes arranged side by side up and down.
Total caliber of heat exchanger tube with the ratio of the caliber of pipe side separating liquid pipe is: 1:5～10.
The heat exchanger tube body that is positioned at the heat exchanger tube body of described dividing plate top runner and is positioned at dividing plate below runner with described dividing plate for being symmetrical arranged.
Described set of heat exchange tubes is 12 rows, and described dividing plate is six layers.
The utility model pipe heat exchanger, wherein heat exchanger tube is pipe with small pipe diameter, pipe external diameter≤4mm.In heat exchanger inside, be provided with dividing plate, the effect of this dividing plate is the mobile path of fluid formation to shell-side, the fluid of shell-side is flowed along internal heat exchange tubes, guarantee that the fluid of shell-side and the fluid of heat exchanger tube side remain the form of pure adverse current, strengthen heat transfer effect.Because the utility model for be the heat exchanger tube of pipe with small pipe diameter, after the heat exchange caliber of heat exchanger reduces, need to increase heat exchanger tube and prop up the drag losses that way reduces to manage interior sharp increase.This heat exchanger branch road number determination method is: heat exchange amount and the pipe internal resistance loss of heat exchange caliber 7mm heat exchanger of take is standard, guarantee the heat exchanger that caliber is reduced to 4mm and heat exchange amount reaches or approach (in 5%) former heat exchanger tube 7mm when following, and pipe internal resistance loses increase within reason (in 2 times).Therefore, after the caliber of heat exchanger reduces, the heat exchanger tube of heat exchanger props up way can be increased a lot, the way of propping up too much heat exchanger tube can cause the fluid that flows to each heat exchanger tube how much to differ, make the degradation of heat exchange performance of heat exchanger, because, the present invention by control the size of total caliber of heat exchanger tube control heat exchanger tube quantity number, thereby on the basis that guarantees heat exchange property, maintain heat exchanger tube internal resistance equilibrium of forces.Because the utility model for the caliber of heat exchanger tube than connecting the separating tube of these heat exchanger tubes, the caliber of collector tube is little a lot, so the utility model proposes a kind of new heat exchanger tube arrangement mode, be about to two heat exchanger tubes and be arranged above and below.The advantage of this mode is: shorten the length of separating tube, collector tube, make the structure of heat exchanger compacter, reduce the disequilibrium that heat exchanger tube side liquid distributes.In heat exchanger, the quantity of pipe with small pipe diameter heat exchanger tube and pipe range adopt the method for numerical simulation to determine according to the heat exchange amount of heat exchanger and the loss of pipe internal resistance.

Wherein: 1-housing; 2-heat exchanger tube; 3-dividing plate; 4-pipe side separating liquid pipe; 5-pipe side collector tube; 6-shell-side inlet pipe; 7-shell-side outlet.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated, as shown in Figure 1, the utility model pipe heat exchanger is mainly comprised of: the housing 1 of steel and plastic composite material, heat exchanger tube 2, dividing plate 3, pipe side separating liquid pipe 4, pipe side collector tube 5, shell-side inlet pipe 6 and shell-side outlet 7.First the heat exchanger tube 2 of heat exchanger inside is two formation set of heat exchange tubes that are arranged above and below, then each group is connected in parallel on pipe side separating liquid pipe 4, collector tube 5.Fluid enters into a heat exchanger from pipe side separating liquid pipe 4, then divides and flows in each heat exchanger tube 2, then flow in pipe side collector tube 5 last outflow heat exchanger.Pipe external diameter≤the 4mm of heat exchanger tube, total caliber of heat exchanger tube is 1:5～10 with the ratio of the caliber of pipe side separating liquid pipe 4, when the ratio of both calibers is 1:7, heat transfer effect is best.One other fluid enters in heat exchanger from shell-side inlet pipe 7, flows, finally from pipe side outlet pipe outflow heat exchanger under the guide functions of the dividing plate 3 of heat exchanger inside along heat exchanger tube 2.Two kinds of heat exchanging fluids keep the liquid form of pure adverse current substantially in heat exchanger inside.
