The utility model content
The utility model has solved above-mentioned technical problem, and providing a kind of can increase heat exchange area greatly, improves the heat exchanger of heat exchange effect.
The utility model is achieved in that a kind of energy-efficient heat exchanger; Comprise horizontally disposed cylindrical shell; The left and right upside of this cylindrical shell is respectively equipped with the thermal medium import and export, and the left and right end of this cylindrical shell is respectively equipped with left and right bobbin carriage, on this left and right bobbin carriage respectively correspondence be provided with that cold medium goes out, import; Level is provided with the heat exchanger tube of several cooling media flow in the said cylindrical shell, and each said heat exchanger tube outer wall is being provided with several circular arc nest plates along its length direction spacer sleeve.
The utility model also has following additional technical feature:
Each forward and backward two ends of said circular arc nest plate is the circular-arc of evagination, and upper/lower terminal is shape linearly.
Open several through holes on each said circular arc nest plate, each through hole supplies a said heat exchanger tube to pass.
Said through hole periphery on each said circular arc nest plate is provided with flange, and the length of this flange is the interval of adjacent two circular arc nest plates.
Each said heat exchanger tube inwall forms several fins.
Staggered several deflection plates that is provided with in the said cylindrical shell.
The two ends of each said heat exchanger tube are separately fixed on the tube sheet that is arranged at the left and right two ends of cylindrical shell.
Can know that from above technical scheme the utility model has increased the heat exchanger tube outside and inboard heat exchange area through circular arc nest plate and fin, has greatly strengthened heat-transfer effect, has improved the heat exchange property of heat exchanger.
Description of drawings
Fig. 1 is the cross-sectional schematic of a kind of optimal way of the utility model;
Fig. 2 is the front elevational schematic of the circular arc nest plate of the utility model;
Fig. 3 is the part section signal enlarged drawing that the circular arc nest plate of the utility model cooperates with heat exchanger tube;
Fig. 4 is the sectional stereogram of the heat exchanger tube of the utility model.
The specific embodiment
Specify the utility model below in conjunction with Fig. 1 to Fig. 4:
Said heat exchanger comprises horizontally disposed cylindrical shell 1; The left and right upside of this cylindrical shell is respectively equipped with thermal medium import and export 11,12; The left and right end of this cylindrical shell is respectively equipped with left and right bobbin carriage 13,14; On this left and right bobbin carriage respectively correspondence be provided with that cold medium goes out, import 15,16, level is provided with the heat exchanger tube 2 of several cooling media flow in the said cylindrical shell, the two ends of each said heat exchanger tube are separately fixed on the tube sheet 17 that is arranged at the left and right two ends of cylindrical shell; Each said heat exchanger tube outer wall is being provided with several circular arc nest plates 3 along its length direction spacer sleeve.After thermal medium flow to from the thermal medium import, heat was passed to the circular arc nest plate, and the circular arc nest plate carries out heat exchange through heat exchanger tube and the cold medium in it.This structure is directly compared at heat exchanger tube outer wall moulding fin with existing, and it has increased heat exchange area greatly, has improved the heat exchange effect.
In the utility model, each said circular arc nest plate 3 forward and backward two ends is the circular-arc of evagination, and upper/lower terminal is shape linearly; Circular-arc and the cylinder inboard wall shape approximation of evagination; Can the area of circular arc nest plate be done more; Make the gap smaller of circular arc nest plate and cylinder inboard wall, this structure not only makes the contact area of circular arc nest plate and thermal medium increase greatly, and can prevent the crossfire phenomenon; And circular arc nest plate upper/lower terminal is designed to linearity, helps thermal medium baffling in cylindrical shell, improves the heat exchange effect.In implementation process, open several through holes 31 on each said circular arc nest plate 3, each through hole supplies a said heat exchanger tube to pass, and that is to say that a circular arc nest plate can be set on several heat exchanger tubes simultaneously, not only saves material, and easy for installation.The utility model also said through hole 31 peripheries on each said circular arc nest plate is provided with flange 32, and the length of this flange is the interval of adjacent two circular arc nest plates.Flange length can be made different length according to the medium operating mode, but should guarantee that flow area and medium fluidised form between the circular arc nest plate are the best.
In implementation process, each said heat exchanger tube 2 inwall forms several fins 21, can further increase heat exchange area; Fin can be made various ways, but should rationally make according to difficulty of processing and medium operating mode.Also staggeredly in cylindrical shell 1 be provided with several deflection plates 4, make thermal medium baffling in cylindrical shell, and fully contact the formation PARALLEL FLOW, with further raising heat exchange effect with the circular arc nest plate.The circular arc nest plate of the utility model can be connected through the mode of expanded joint with heat exchanger tube, firm and reliable connection not only, and can avoid the generation of thermal contact resistance.
From the above, the utility model not only increases heat exchange area at the heat exchanger tube outer wall through the circular arc nest plate, and in heat exchanger tube, increases heat exchange area through fin, has strengthened heat-transfer effect to the utmost, has improved the heat exchange property of this heat exchanger.
Above-mentioned embodiment only supplies to explain the usefulness of the utility model; And be not to be the restriction to the utility model; The those of ordinary skill in relevant technologies field; Under the situation that does not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to the category of the utility model.
