Abstract
The utility model discloses a high-efficiency U-shaped heat exchanger which comprises a U-shaped pipe assembly, wherein the U-shaped pipe assembly is fixed on a supporting plate (1), the U-shaped pipe assembly comprises a plurality of coaxially arranged U-shaped pipes (2), flow separating plates (3) which are in staggered arrangement at intervals are arranged on the supporting plate (1) obliquely, a movable flow guider (6) is arranged in the straight-pipe segment of each U-shaped pipe, and the flow guider comprises flow dividing rings (4) which are arranged at intervals and flow guiding sheets (5) which are fixed in the flow dividing rings in a staggered way and penetrate through the flow dividing rings. When a fluid enters from one end from each U-shaped pipe, because of the action of a baffle plate at the inlet of each U-shaped pipe, the fluid is dispersed and separated; and after the fluid enters each U-shaped pipe, because of the action of the flow guider, the fluid is blocked by each flow guiding sheet, and the flowing resistance of the fluid is increased, so that a backflow is generated by the fluid in the flow guider, the flowing time of the fluid in each U-shaped pipe is prolonged, and the invention is beneficial to the sufficient heat transfer of the fluid, thereby improving the heat transfer efficiency of the heat exchanger.
Description
Technical field
The present invention relates to a kind of heat exchanger, especially relate to the high U-shaped heat exchanger of a kind of heat exchanger effectiveness.
Background technology
Heat exchanger is the main device that fluid is realized heating or cooling, and is very universal in industry.Heat exchanger mainly can be divided into heat-exchangers of the plate type and tubing heat exchanger by structure, and wherein the tubing heat exchanger range of application is wider, and heat exchanger effectiveness is also higher.And have tubing heat exchanger now owing to the managed length and the influence of shape and structure, and tube cavity is straight-through shape, and the speed that fluid is flowed in pipe is fast, and flow resistance is little, and fluid thermal weak point swap time causes the heat transfer efficiency of heat exchanger high not enough.
Summary of the invention
Problem at tubing heat exchanger in the above-mentioned prior art exists the invention provides the high U-shaped heat exchanger of a kind of heat exchanger effectiveness.
The technical scheme that the technical problem to be solved in the present invention is taked is: described efficient U-shaped heat exchanger comprises the U-shaped pipe assembly that is fixed on the gripper shoe, described U-shaped pipe assembly is made up of the some U-shaped pipes that are coaxially set, gripper shoe is provided with interval-staggered deflector, described deflector is obliquely installed, in U-shaped pipe straight length, be provided with movable air deflector, described air deflector comprises the splitting ring that is provided with at interval and interior and pass the flow deflector of splitting ring because of fixing on splitting ring, and described flow deflector is crisscross arranged.
The present invention when fluid when the U-shaped pipe enters, because the effect of U-shaped pipe import department dividing plate, make fluid be disperseed to isolate, after fluid enters in the U-shaped pipe, because the effect of air deflector, fluid is subjected to flow deflector and hinders, increase the flow resistance of fluid, made fluid in the U-shaped pipe, produce backflow, prolonged the flowing time of fluid in the U-shaped pipe, help the fluid sufficient heat exchange, thereby improved the heat transfer efficiency of heat exchanger.

The specific embodiment
At Fig. 1, Fig. 2, among Fig. 3 and Fig. 4, described efficient U-shaped heat exchanger comprises and is fixed on U-shaped pipe assembly on the gripper shoe 1, described U-shaped pipe assembly is three rows, every row is made up of four U-shaped pipes 2 that are coaxially set, the symmetrical center line that is the U-shaped pipe is positioned on the same axis, described U-shaped pipe is made by stainless steel or other metal material, gripper shoe is provided with interval-staggered cutoff board 3, cutoff board is that metallic plate is 30-60 ° and is obliquely installed, cutoff board preferably is circular arc, also shape linearly, in every U-shaped pipe straight length, be provided with can be in the U-shaped pipe movable air deflector 6, described air deflector is by forming every four stainless steels that are provided with splitting ring of making 4 and the flow deflector 5 that passes in the splitting ring between the upper and lower, flow deflector is fixed in the splitting ring, air deflector is made with stainless steel, the total length of air deflector is slightly less than U-shaped pipe flow development length, the air deflector outside dimension is less than the U-shaped bore, described flow deflector 5 cross sections are cross and are crisscross arranged, also can be the circular arc stagger mode, described flow deflector thickness is identical with the baffle liner wall thickness.
Claims (2)
1. efficient U-shaped heat exchanger, it comprises the U-shaped pipe assembly that is fixed on the gripper shoe (1), described U-shaped pipe assembly and U-shaped pipe (2) that have same symmetry axis identical by some opening directions formed, it is characterized in that: gripper shoe (1) is provided with interval-staggered cutoff board (3), described cutoff board is obliquely installed, in U-shaped pipe (2) straight length, be provided with movable air deflector (6), described air deflector comprises the splitting ring (4) that is provided with at interval and is fixed on splitting ring interior and pass the flow deflector (5) of splitting ring, described flow deflector is fixed in the splitting ring, and the flow deflector cross section is cross or circular arc is arranged in a crossed manner.
2. efficient U-shaped heat exchanger according to claim 1 is characterized in that: described cutoff board (3) is circular arc.
