Abstract
The utility model relates to a fatigue resistant protector for a heat exchange pipe of a heat exchanger, which is designed for solve the problems that the case of fatigue damage of a heat exchange pipe can easily occur due to the vibration. The utility model is installed on a plate hole of a baffle plate of a heat exchanger, and the annular wall thereof forms a circular arc shape; the utility model can protect the heat exchange pipe from the shearing and the bumpiness of the edge of the plate hole of the baffle plate, and the problem of the fatigue damage of the heat exchange pipe can be thoroughly solved. The utility model has the advantages of simple structure, easy fabrication, convenient installation, and obvious fatigue resistant effect.
Description
The utility model relates to heat transfer technology.
The heat exchanger tube that heat exchanger uses has types such as bellows, light pipe, screwed pipe, special pipe, wherein coefficient of heat transfer height, high temperature resistant, descaling function is strong surely belongs to bellows.Because of the thin thermograde of bellows tube wall is little, can reduce wall resistance greatly, improve the inside and outside coefficient of heat transfer of pipe, total heat transfer coefficient is improved.Because the bellows wall thickness only is 0.5-1.0mm,, reduce construction cost simultaneously, economize material 50-75%, the economic benefit highly significant so can reduce equipment volume.Bellows is a kind of tangent continuously by big or small circular arc, interior profile such as undulatory thin-walled tube, and the high official post fluid between its crest and trough has been subjected to strong disturbance.This disturbance also from the three-dimensional motion of outer fluid in the pipe, therefore makes the degree of its disturbance more strong and thorough, even rate of flow of fluid is very low, also can make it become turbulence state.Under the duty, heat exchanger tube is installed on the deflection plate.The vibration that is produced of flowing of outer fluid can cause heat exchanger tube tube wall and deflection plate plate hole edge to produce collision, rub and shear in the heat exchanger tube, and heat exchanger tube is damaged because of tired.And bellows approaches the reason that is turbulence state with interior outer fluid because of its wall, so Oscillation Amplitude strengthens, suffered destruction is also bigger.
The purpose of this utility model just provides the anti-tired protector of a kind of heat exchanger heat-exchanging tube.This utility model is achieved in that as shown in drawings, and anti-tired protector 3 is located in the plate hole 2 on the heat exchanger deflection plate 1, and anti-tired protector 3 is annular, and its ring wall is circular-arc, and its two ends bore is all greater than plate hole 2 diameters.
After adding this anti-tired protector 3 on heat exchanger deflection plate 1 all plate holes 2, because of the protective effect of protector 3 circular-arc ring walls, heat exchanger tube can not sheared again because of vibration, anti-tired effect is particularly remarkable.The anti-tired protector structure of this heat exchanger tube is simple in addition, easily processes and location and installation very economical practicality.
Accompanying drawing is this utility model schematic diagram.
