Description of drawings
Fig. 1 is shell heat exchanger one embodiment schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in further detail.
as shown in Figure 1, be shell heat exchanger one embodiment schematic diagram of the present invention, shell-and-tube heat exchanger of the present invention, it comprises tube sheet (not indicating), be positioned at the housing (not indicating) of tube sheet periphery, be distributed in the heat exchanger tube 10 that connects described tube sheet in housing, end cap 6 and flange 1, described tube sheet comprises upper perforated plate 5 and lower perforated plate 2, described housing comprises cylindrical shell 3, the thermometric joint chair 7 affixed with upper perforated plate 5, the central tube 4 that connects described cylindrical shell 3 and described upper perforated plate 5, the tube side joint 9 that is positioned at the shell side joint 8 of cylindrical shell 3 one ends and is positioned at cylindrical shell 3 other ends, described upper perforated plate 5 is connected with described end cap 6 and forms the first cavity (not shown), described lower perforated plate 2 is connected with described flange 1 and forms the second cavity (not shown).
Flange 1 be connected by heat exchanging piece, size between Φ 10mm～Φ 10000mm, flange 1 be connected by screw by heat exchanging piece, replacing maintenance for convenience detach.
Upper perforated plate 5 respectively and adopt between central tube 4 and cylindrical shell 3 and be welded to connect adopts screw to be connected between described end cap 6 and described upper perforated plate 5, sealing employing O type circle or sealing gasket pattern.
Lower perforated plate 2 is welded to connect with cylindrical shell 3 and central tube 4 respectively; Described lower perforated plate 2 adopts screw to be connected with flange 1, adopts the sealing of O type circle or sealing gasket between the two.
Upper perforated plate 5 is connected with end cap 6 and forms the first cavity, and the tube side medium enters the first cavity by tube side joint 9, enters heat exchanger tube 10 after medium is all pressed and carry out heat exchange with the shell side medium in the first cavity.
Lower perforated plate 2 is connected with flange 1 and forms the second cavity, and medium is taken over by tube side and entered the second cavity, after all pressing in the second cavity, evenly enters tube side and shell side media for heat exchange.
On lower perforated plate 2 inboards and flange 1, through hole is shell side medium intake channel, and inducer flow area is adjusted according to central tube 4 sectional areas, guarantees that the shell side medium runner is unimpeded.
Central tube 4 upper end perforates, perforated area is identical with the interior sectional area of central tube 4, guarantees that medium runner is unimpeded.Central tube 4 upper end perforate patterns can be the multiple patterns such as circular hole, the one word hole.
Tube side joint 9 is welded to connect with adpting flange 1 with end cap 6 and tube side joint 9.Shell side joint 8 and cylindrical shell 3 welding when in shell side, pressure medium is too high or too low, discharges or replenish by medium in shell side joint 8 shell sides.
Heat exchanger tube 10 radicals and length are calculated acquisition by heating power.Heat exchanger tube 10 must guarantee that each root length is identical, obtains identical tube side pipe resistance, so that the tube side medium is evenly distributed in tube side.
Heat exchanger tube 10 can according to the heat exchanger structure size characteristic, be arranged to 1 layer to 50 layers coil pipe pattern.After heat exchanger tube 10 is arranged and completed, if there is remaining space in the shell side space, adopt coil pipe, two ends block, and make false heat exchanger tube, fill up the tube side space, guarantee area and the length of shell side medium channel, prevent medium " short circuit " in tube side, affect heat transfer effect.
Heat exchanger tube 10 adopts copper pipe, and copper pipe can be helical form light pipe or helical form finned tube.The heat exchanger miscellaneous part adopts stainless steel or other steel grades.
Whole weld seam that has different mother metals of heat exchanger, weld seam welding fusing point differs greatly, and needs to adopt different welding means and reasonable layout welding sequence, and the mother metal weld seam that fusing point is high welds in advance, welds at last low-melting weld seam.
Upper perforated plate 5 welds in advance with central tube 4, and heat exchanger tube 10 1 ends insert in upper perforated plate 5 welding holes, make heat exchanger tube 10, and lower perforated plate 2 changes in central tube 4 and heat exchanger tube 10, fixes the relative position of heat exchanger tube 10 and upper perforated plate 5 lower perforated plates 2, but does not weld.
Heat exchanger tube 10 and upper perforated plate 5, heat exchanger tube 10 adopts gas brazing with lower perforated plate 2, and welding wire adopts silver wire.Heat exchanger tube 10 and upper perforated plate 5 lower perforated plate 2 front strict cleanings of welding position weldering, wipe oil and oxide skin.Heat exchanger tube 10 and upper perforated plate 5 and lower perforated plate 2 mating holes gaps guarantee within 0.001mm～1mm.
During heat exchanger tube 10 welding, adopt the wielding neck order, reduce between weld seam influencing each other, improve welding quality.
The invention provides a kind of compact conformation, the shell-and-tube heat exchanger of heat transfer efficient and the manufacture craft of heat exchanger: the contactless air stream drives of novel high speed, dynamic balancing that can the rotating band vane rotor detects drive unit; Compact conformation of the present invention, heat transfer efficient can with fine integrated by heat exchanging piece, reduce the occupation of land vacant lot of overall apparatus; The present invention with integrated by heat exchanging piece after, the shell side medium forms closed cycle in heat exchanger, reduce the contaminated possibility of shell side medium; The mechanism form of this device can be similar compact heat exchanger reference is provided.
