Abstract
The utility model relates to a high efficiency composite laminated tabulate heat exchange device, comprising an exchanger tube, a housing, a support saddle, an end enclosure, a fin, a traverse baffle and a fixed tube sheet. The exchanger tube is fixed on the fixed tube sheet, the housing and the end enclosure are provided with conduit coupling, and the fin and the traverse baffle is tightly sleeved on the exchanger tube. The heat interchanging efficiency of the utility model is high, the same bulk is increased by 40 to 100 percent of heat interchanging area, the short pass of the thermal medium is reduced by more than 95 percent, and the heat transfer coefficient is increased by 100 to 150W/m(2) K. The difference in temperature of the thermal medium is increased by 20 percent. The use life can be reached to more 10 years, which is improved by 2 to 3 times when compared with the traditional shell-and tube heat interchanger.
Description
One, technical field
The utility model relates to a kind of lamination tubular heat exchanger, especially efficient composite laminate tubular heat exchanger.
Two, background technology
The kind of heat exchanger is a lot, and as naked pipe formula heat exchanger and lamination tubular heat exchanger, existing lamination tubular heat exchanger is commonly used welding lamination tubular heat exchanger and screwed pipe tubular heat exchanger.The cooling volume of naked pipe formula heat exchanger is big, the short circuit phenomenon of thermal medium is serious, heat transfer coefficient is poor, service life short (being generally about 3 years), screwed pipe tubular heat exchanger oil cooling but can be strengthened oil and be sidelong hot coefficient, increase the heat exchange area of unit volume, improve cooling effect, but facts have proved, because the restriction of processing technology, gap between tubulation and deflection plate is bigger, and the thermal medium short circuit phenomenon is even more serious, especially along with the prolongation of service time, grease accumulates in the narrow and small groove, thermal resistance is along with increase, and cooling effect descends, and causes heat transfer property poorer.The thermal resistance of welding lamination tubular heat exchanger is also bigger.The deflection plate that supports tubulation in the heat exchanger of said structure also easily becomes flexible, and liquid flows and the impact of oil stream is become flexible tubulation and tube sheet, causes the fluid mixed flow, and service life is short, influences heat exchanger overall structure performance.
At high temperature season, water temperature raises, and the oil temperature of oil cooler is higher to cause drive disk assembly fault rate height, even causes the phenomenon of equipment major accident.
The purposes of heat exchanger is a lot, industries such as iron and steel, oxygen, mine, electric power especially, and running gear friction heat is a lot, must lubricating oil be cooled off with heat exchanger, and heat exchanger is important building block.
Three, summary of the invention
The purpose of this utility model is: a kind of efficient composite laminate tubular heat exchanger is provided, and no thermal medium short circuit, no grease gathers, and thermal resistance is little, and is easy to process, the composite laminate tubular heat exchanger that overall structure and performance are good.
The purpose of this utility model is achieved in that a kind of efficient composite laminate tubular heat exchanger, comprise that heat exchanger tube, housing, bearing, end socket, fin, deflection plate, fixed tube sheet constitute, heat exchanger tube is fixed on fixed tube sheet, housing and end socket are provided with pipe joint, it is characterized in that fin and deflection plate tightly are enclosed within on the heat exchanger tube.
Improvement of the present utility model also comprises: in heat exchanger, connects positive cuboid and partly installs lamination additional on the tubulation between deflection plate, and the spacing 2-3mm between the lamination, heat exchange area per unit volume can improve a lot.The utility model can be that the medium that is cooled is outer and circulate between lamination at pipe, and common heat exchanger is mobile in pipe.
Characteristics of the present utility model are: adopt advanced interior expansion tube process, make tubulation and lamination, deflection plate and tube sheet and other support plate be expanded into an integral body, basic gap of eliminating between tubulation and baffling pipe, reduce the short circuit phenomenon of thermal medium significantly, tubulation rigidity greatly improves, thereby increases the service life.
Heat exchange efficiency of the present utility model improves, and the equal volume heat exchange area increases 40-100%, and the thermal medium short circuit phenomenon reduces more than 95%, and heat transfer coefficient increases 100-150W/m
2K.The temperature difference of thermal medium increases more than 20%.Can reach service life more than 10 years, improve 2-3 doubly than traditional tubular heat exchanger.Take out stains and be better than traditional rolling tubular heat exchanger and screwed pipe tubular heat exchanger.The utility model can also be changed the existing composite laminate formula of user heat exchanger core, for the user saves investment.
Four, description of drawings
Fig. 1 is the cross section structure schematic diagram of the utility model structure.
Five, the specific embodiment
As shown in the figure, efficient composite laminate tubular heat exchanger, similar to traditional heat exchanger, comprise that heat exchanger tube 1, housing 2, bearing 3, end socket, fin 4, deflection plate, fixed tube sheet constitute, heat exchanger tube is fixed on fixed tube sheet, fixed tube sheet in the end near the end socket place.Housing and end socket are provided with pipe joint, and end socket is provided with pipe joint and connects the cooling medium that imports tubulation.And the pipe joint on the housing connects the medium that is cooled.Fin and deflection plate are enclosed within earlier on the heat exchanger tube, expansion tube process in the utility model adopts, promptly with balls such as steel ball under the atmospheric pressure effect in tubulation the distending tubulation, original fin and deflection plate are enclosed within to have little gap and is filled with on the heat exchanger tube.Thereby fin and deflection plate tightly are enclosed within on the heat exchanger tube.In heat exchanger, connect positive cuboid and partly add folding fin 4 on the tubulation between deflection plate, the spacing 2-3mm between the lamination, heat exchange area per unit volume greatly improves.Adopt advanced interior expansion tube process, make tubulation and lamination, deflection plate and tube sheet and other support plate be expanded into an integral body, eliminate the gap between tubulation and baffling pipe at all, reduce the short circuit phenomenon of thermal medium significantly, tubulation rigidity greatly improves, thereby increases the service life.As shown in the figure, generally be circular in the heat exchanger cross section, connect rectangle or square in the circle, connect rectangle among the figure, add the folding fin on the tubulation in it between spreading side's body part deflection plate, remainder is the tubulation of not folding fin.
Claims (3)
1, a kind of efficient composite laminate tubular heat exchanger, comprise that heat exchanger tube, housing, bearing, end socket, fin, deflection plate, fixed tube sheet constitute, heat exchanger tube is fixed on fixed tube sheet, and housing and end socket are provided with pipe joint, it is characterized in that fin and deflection plate tightly are enclosed within on the heat exchanger tube.
2,, it is characterized in that on the tubulation between the interior spreading side in heat exchanger cross section body part deflection plate, adding the folding fin by the described efficient composite laminate tubular heat exchanger of claim 1.
