Detailed description of the invention
Below in conjunction with the preferred specific embodiment of accompanying drawing the present invention, structure of the present invention is further described.
Shown in Fig. 5, the present invention includes shell 1 and bottom 2, shell 1 entirety is that the bottom of cylindrical, described shell 1 is tightly connected by ring flange 11 and bottom 2; According to the material hardness of shell 1, ring flange 11 can be and shell 1 integrative-structure, can be also absolute construction, and during absolute construction, shell 1 bottom outer wall establishes one with shell 1 with the integrative-structure ring flange 10 of material.Shell 1 and bottom 2 form an annular seal space, be provided with heat-exchange tube 3, and be filled with cooling fluid in annular seal space, and cooling fluid absorbs the heat that heat-exchange tube 3 distributes.Conveniently clean and maintenance, the cooling fluid import and export of annular seal space, and the import and export of the cooled medium of heat-exchange tube is drawn by described bottom.
Forming primarily of many group helix tubes referring to figs. 1 through the heat-exchange tube 3 described in Fig. 4, is be described structure of the present invention for two groups in Fig. 1 to Fig. 4.Heat-exchange tube 3 is made up of first group of helix tube 31, second group of helix tube 32, charging house steward 33, discharge header pipe 34 and discharging straight tube 35, first group of helix tube 31 and second group of helix tube 32 are formed by more than two sub-pipes of spiral side by side, in Fig. 1 to Fig. 4, first group of helix tube 31 and second group of helix tube 32 adopt 8 spiral pipes respectively, the sub-pipe bottom of each spiral all connects charging house steward 33, top all connects discharge header pipe 34, each spiral pipe all adopts the conduit of below diameter 10mm, many the sub-pipe of spiral can limited increase radiating surface side by side, it is flat helix tube that many sub-pipes of spiral form a spiral section, first group of helix tube 31 and second group of helix tube 32 are the flat helix tube of two same length, in order to spiral section and the cooling fluid energy uniform contact of first group of helix tube 31 and second group of helix tube 32, the spiral section of the spiral section of first group of helix tube 31 and second group of helix tube 32 is the stacked setting in interval, to that is to say in manufacturing process coiling well wherein after one group of helix tube 31, another group helix tube carries out coiling in the gap of last helix tube 31.Identical radiating effect is reached between the sub-pipe of each spiral in order to first group of helix tube 31 and second group of helix tube 32, first group of helix tube 31 and second group of helix tube 32 medium position be formed one by and come the torsion structure of internal helicoid pipe and the sub-pipe location swap of external helicoid 180 degree, then in first group of helix tube 31, top is close at the sub-pipe 311 of the spiral at center side by side, after revolving turnback, this spiral pipe 311 bottom will and come outermost; Equally, form each spiral pipe of second group of helix tube 32, after the degree revolving turnback, the sub-pipe position of each spiral, interior outside exchanges, and reaches each spiral tube heat exchange effect identical, avoids local temperature difference comparatively large, improves heat exchanger effectiveness.Conveniently form the sub-pipe coiling of spiral of first group of helix tube 31 and second group of helix tube 32, and be convenient to cooling fluid circulation, described first group of helix tube 31 and each helical layer of second group of helix tube 32 is intersegmental is provided with resilient barrier fastener (not shown in FIG.), each helical layer section can establish 2 ~ 4 resilient barrier fasteners to carry out isolation separately, reaches the object positioned spiral section.
With reference to shown in Fig. 5, conveniently see heat-exchange tube 3 winding structure of the present invention clearly, three sub-pipes 311 of spiral are adopted to form single group helix tube 31 in figure, article three, spiral pipe 311 bottom all connects charging house steward 33, top all connects discharge header pipe 34, discharge header pipe 34 connects discharging straight tube 341, article three, list group helix tube 31 medium position that the sub-pipe 311 of spiral is formed revolves turnback, form the torsion structure 30 of 180 degree, after carrying out 180 degree of rotations when the sub-pipe 311 of three spirals that is to say side by side is coiling to middle section position, continue coiling again.
Shown in Fig. 5, import in heat-exchange tube 3 for the ease of the liquid that need be cooled or the gas medium that is cooled, and be convenient to cooling fluid and inject and discharge shell 1 and bottom 2 and form an annular seal space, three-way connection 21 is provided with at the center of described bottom 2, the center line of straight-through section of three-way connection 21 overlaps with the center line of bottom, is socketed with the cooling fluid flow guiding casing tube 22 that is placed in first group of helix tube 31 and second group of helix tube 32 inner ring on the top of three-way connection 21; Described charging house steward 33 draws through described bottom 2 non-central location, is also namely provided with the charging hole 23 of drawing for charging house steward 33 at bottom 2 non-central location, and charging hole 23 is cooled medium entrance; If need consider, cooled medium discharging and charging are in same direction, described discharge header pipe 34 is connected with a discharging straight tube 341 of drawing through the straight-through section of described cooling fluid flow guiding casing tube 22 and three-way connection 21, the bottom mouth of pipe of discharging straight tube 341 is cooled media outlet, in order to better sealed discharging straight tube 341, the bottom end opening of three-way connection 21 is provided with the sealing-plug of a band discharge opening; Bottom 2 is positioned at outside cooling fluid flow guiding casing tube 22 and is arranged with cooling liquid inlet 24, remain with gap between the straight-through section inwall of described discharging straight tube 341 outer wall and three-way connection 21, the side of three-way connection 21 is cooling liquid outlet 25.In use procedure, the liquid that need cool or gas enter from charging house steward 33, flow simultaneously, after discharge header pipe 34 gathers, draw through discharging straight tube 341 from the bottom of first group of helix tube 31 and second group of helix tube 32 to top; Cooling fluid then enters bottom annular seal space from cooling liquid inlet 24, then overflow into from cooling fluid flow guiding casing tube 22 top, the gap retained between the straight-through section inwall finally by discharging straight tube 341 outer wall and three-way connection 21 is that cooling liquid outlet 25 is discharged from the side of three-way connection 21.
Cooling fluid membrane layer 4 is filled with between the inwall of described heat-exchange tube 3 and shell 1, thermal insulation layer 4 stops that cooling fluid directly flows through from heat-exchange tube 3 and the gap of the inwall of shell 1, thus cause the cooling fluid in heat-exchange tube 3 internal clearance not circulate, or circulation is comparatively slow, causes heat-exchange tube 3 to dispel the heat slowly.
In order to better ensure that heat eliminating medium is by regulation requirement flowing, top or the bottom of described heat-exchange tube 3 are provided with sealing ring 5.
