Definitions
- This invention relates to a heat exchanger. More particularly, this invention relates to a heat exchanger for a nuclear reactor. Still more particularly, this invention relates to a heat exchanger of composite structure which provides a uniform pressure pattern to a medium flowing therethrough.
- the heat exchangers of composite structure have been used in nuclear reactors for absorbing the heat carried by the reactor coolant.
- These heat exchangers have been comprised of a plurality of parallel connected heat exchange units having a heat absorbing medium flowing therein and have been arranged in a casing so that the reactor coolant flows directly through the heat exchanger casing over the heat exchange units.
- the heat exchanger units which may be of any polygonal shape be erected in a plurality of open-ended containers having closed walls for disposition on stilts, a support lattice or a grating so that the containers are arranged alongside each other in situ with the gaps between each pair of adjacent containers bridged by sealing means at top and bottom.
- a positive pressure acts on the container side walls at the sealed ends which is either internal or external to the walls depending on the end of the container involved.
- the lateral walls must be strengthened. This requires not only extra material but also extra space since the walls have generally been made of corrugated plates.
- this invention provides a heat exchanger comprising a plurality of open-ended spaced heat exchanger units for absorbing heat from a flow of coolant passingtherethrough with a throttling means disposed in the spaces between adjacent heat exchanger units for throttling the flow of coolant through the spaces.
- the throttling means includes a plurality of movably mounted spaced throttling elements which are supported on the wall of one heat exchanger unit and which bear against the wall of an adjacent heat exchanger unit at different levels.
- the invention avoids any unbalanced pressure loading on the exterior walls of the units by substantially equalizing the pressures on opposite sides of the exterior walls. Further, the invention allows adjacent heat exchanger units, assuming they are of square shape, to have two opposite walls formed of i mperforate plates or sheets while the other two walls are formed of spaced apart plate strips so as to form perforated walls. In such a modification there is a direct pressure equalization between the interior of the units and the spaces between adjacent units.
- the invention provides some temperature equalization between the coolant flowing through the spaces between adjacent units and the coolant flowing in the units.
- the degree of temperature equalization can be improved by staggering the apertures in the exterior walls of adjacent units relative to each other between adjacent throttling elements so that a flow of coolant can be transversely directed from between the units into the units.
- the transverse flow is substantially smaller than the flow of coolant in the units.
- the heat exchanger units are vertically disposed to each other and each is provided with tu-be bunches for the flow of heat absorbing medium therethrough which are disposed in a scaffold-like structure having longitudinal and transverse struts.
- the transverse struts of adjacent uni-ts are interconnected in a number of stages or tiers by the throttling elements and the longitudinal struts are aligned in parallel relation to the direction of flow of coolant over the tubes.
- the outside units of the heat exchanger are sealed or throttled with respect to the walls of the casing in which the heat exchanger is mounted.
- the throttling elements comprise a sheet metal strip which is mounted on the wall of one unit at a level below the point of contact with the adjacent unit.
- the throttling elements can be formed of bar material of U- or T-shaped sections.
- FIG. 1 illustrates a cross-sectional view of a nuclear reactor having a heat exchanger of the invention disposed therein;
- FIG. 2 illustrates a partial cross-sectional view of a pan of adjacent heat exchange units of the heat exchanger of FIG. 1;
- FIG. 3 illustrates an enlarged cross-sectional view of a throttling means between the heat exchanger units of FIG. 2;
- FIG. 4 illustrates a modification of the invention.
- a nuclear reactor in which the invention can be utilized includes a reactor core R which is received in a pressure-resistant structure, for instance, of concrete.
- a large number of heat exchange units E are disposed below the core R in a passage K which in this particular case forms the casing of the heat exchanger according to the invention and cover plates A are provided to seal the space between the elements and the heat exchanger casing wall.
- those boundary walls of the units which are adjacent the casing wall take the form of strengthened sheetmetal walls while the spaces S between the units are interconnected in stages by throttling elements in the manner clearly apparent from FIG. 2, which will be described hereinafter.
- a reactor coolant e.g. CO flows downwards through the reactor core and passes therefrom to the heat exchanger which is formed by the units E to heat a mediume.g., water, flowing through the units E.
- the coolant is throttled by the tiered throttling elements in the spaces S between the units E.
- the coolant then passes from the heat exchanger through circulating lines L associated with circulating blowers U upwardly to re-enter the reactor core.
- the tubes 3 through which the heat absorbing medium flows are arranged in bunches of parallel flat-type tube coils so that the coolant flows transversely over the tubes.
- FIG. 2 shows the tubes 3 disposed in only one of the heat exchanger units but it is to be noted that all the units have similar tubes mounted therein during use.
- the heat exchanger is of a size which measures 2 m. x 2.5 m. x 10 m. and weighs about 100 tons.
- the straight parallel portions of the tubes 3 are formed with circular ribs 4 and interconnected by unribbed reversing bends 5 to form flat parallel tube panels through which the heat absorbing medium flows.
- the units enclose the tube panels with a scaffold-like structure comprising longitudinal and transverse struts or the like, in the form of four bearing longitudinal struts 6 to which transverse struts 7, 8, embodied as T bearers, are welded in a number of tiers with angle-member bearers 9, 10 forming a top frame and bottom frame respectively.
- the tube panels are secured by flanges 11 to the webs 12 of the transverse struts 7, such webs forming support or bearing edges 12.
- the webs 12 are in turn welded to the arms of the longitudinal struts 6 which are contiguous on the opposite sides. Conveniently, the webs 12 are disposed in staggered relationship to one another on the two opposite sides of each unit.
- the tube panels When the units are assembled, the tube panels are placed in a plane parallel to the plane of the drawing, then introduced between the transverse struts which have the edges 12, and secured by means of the flanges 11 thereto. Only after all the tube panels are secured is the front frame welded on. In the drawing, the visible transverse struts of the rear frames of the units are indicated by reference character 8.
- the transverse struts of adjacent units are interconnected at least in a number of stages by throttling elements.
- the space 13 between the units 1 and 2 is bridged in a number of tiers by throttling elements 14, so that the flow of gas around the pipes is severely throttled in the spaces 13. Since the gas flow is intensively throttled not only by the elements 14 in the spaces 13 between adjacent units but also by the edges 12 near the unribbed tube bends, most of the gas flow is confined to the region of the ribbed straight tube portions 3. Consequently, the temperature distribution of the gas at the end of the heat exchanger is uniform over the whole crosssection. Also, there is pressure equalization in the sections between the various units and between the spaces which exist between adjacent units so that there is no unequal stressing of the insides or outsides of the various units.
- the units can be specially devised to produce, as compared with the lengthwise flow of the heat absorbing medium through the units, a reduced transverse flow between the units and the spaces.
- One way of producing such a transverse flow is for the transverse struts of adjacent units to be vertically staggered relatively to one another.
- inclined baffles can be provided near the tube bends between two transverse struts of the same unit, or else the entry cross-section of that proportion of the medium of one unit which flows through the units can be reduced relatively to the entry cross-section of the other, for instance, by appropriately devising the top frame of the angle-member bearers 9, and the outflow cross-section of another unit separated from the first-mentioned unit by a number of units can be reduced similarly in relation to the other outflow cross-sections by similarly devising the angle-member bearers 10 which form the bottom frame.
- the throttling elements to completely seal off the various space sections from one another; all that is needed is for the flow in the spaces to be intensively throttled.
- the lengthwise gas flow through the spaces which are e.g. 5 cm, wide, is small as compared with the gas flow through the units; also, the lengthwise gas flow through the spaces is mixed in the various sections with cooled gas from the units so that the gas flow from the spaces has substantially the same temperature as the gas flow in the units. Consequently, there is substantially uniform thermal stressing of the constructional elements.
- the transverse struts 7 as well as the transverse struts S of adjacent units are interconnected by throttling elements 14 which are disposed in all tiers of adjacent units to be bridged; however, arrangements are of course possible wherein only some of the transverse struts of adjacent units are interconnected by throttling elements.
- the throttling elements 14 take the form of sheetmetal strips which are borne by continuous projections or troughs 15 contrived on the transverse struts 7 of one unit.
- the strips 14 are wider, preferably about 1.4 times wider, than the longest space 13 between any two adjacent units and extend at an inclination over the space against the corresponding transverse strut 7 of the adjacent unit under a slight positive gas pressure of the coolant.
- the chain-dotted lines in FIG. 3 indicate how the strips 14 are secured to the strut 7 by means of numbered retaining stirrups 16, before and after the various units are slid together. Once the units have been slid together, the stirrups 16 are removed allowing the throttling strips 14 to automatically take up the inclined position shown. It the stirrups 16 are numbered, a continuous check can be made during assembly to see that all the strips 14 have definitely been released by the stirrups 1-6.
- the sealing lines of the strips 14 extend horizontally between the strips 14 and the two adjacent struts 7; however, arrangements are of course possible wherein the sealing lines extend at an inclination to the vertical. This feature depends mainly upon how the various units are disposed and constructed.
- the space 13 is sealed at the top by a T-bar 17 and the pressure of the gaseous heat vehicle on the angle-member bearers 9 of two adjacent units.
- the web of the T-bar 17 in the space centers the bar while the bar flanges bridge the space.
- the transverse struts 7 of adjacent units can be interconnected in stages by U-bars 18 over the space as shown by example in chain-dotted lines in FIG. 2.
- the units are erected on a support grating which is formed from box girders; one such grating 19 being shown in FIG. 2.
- the heat exchanger is so devised in accordance with the invention that the bearing box girders need not be specially sealed 01f from the units at the bottom of the heat exchanger.
- the outer units of the heat exchanger can have, for instance, on their outsides, a strengthened continuous wall (FIG. 1).
- a strengthened continuous wall FOG. 1
- the spaces between the outsides of the outer elements and the heat exchanger casing wall is bridged in tiers or stages by sealing elements, similarly to the tiered or stagewise sealing of the spaces between the various units.
- edges 21 are disposed in tiers or stages or stories on the cylindrical casing wall 20 of the heat exchanger for cooperation with the throttling elements 14 of the adjacent units.
- a T-bar 22 Disposed at the top is a T-bar 22 Whose web engages with a centering action in the space between the casing wall and the outer units, while the flanges of the bar bear the one on the top edge 21 of the casing wall and the other on the top bearers 9 of the outer units.
- throttling element is not to be understood in the present context in the sense of an element eifecting a tight sealing effect; rather, the term is intended to indicate an element which serves to throttle the flow of the medium through the spaces so that the pressure pattern of the medium flowing through the spaces is substantially adapted to the pressure pattern of the medium flowing around the flow passages in the units. This effectively prevents the formation of short-circuit flows along the spaces which short-circuit flows would cause thermodynamic losses impairing eflicient heat exchange and also lead to heavy thermal stressing of the materials used for the constructional elements.
- a heat exchanger comprising a plurality of openended heat exchanger units for absorbing heat from a flow of heated coolant passing therethrough, each pair of adjacent heat exchanger units being sealingly connected to each other at the end thereof and being disposed in a freely expandible manner to each other at the opposite end thereof to define a gap therebetween, and throttling means movably mounted across said gap between each said pair of adjacent heat exchanger units for throttling a flow of heated coolant passing through said gap whereby the pressure pattern of the flow of heated coolant passing through each said gap substantially corresponds to the pressure pattern of the flow of heated coolant passing through said heat exchanger units defining said gap.
- each of said heat exchanger units has at least one perforated wall adjacent a perforated wall of an adjacent heat exchanger unit, said throttlingmeans interconnecting the imperforated areas of said adjacent perforated walls in vertical spaced tiers.
- each of said heat exchanger units includes a scaifold-like structure comprising longitudinal struts and T-shaped transverse struts connected together and a plurality of tube panels for conveying a heat absorbing medium therethrough enclosed within said scaffold-like structure, each said tube panel being secured to the web of one of said transverse struts, said throttling means interconnecting said transverse struts of each pair of adjacent heat exchanger units.
- a plurality of spaced apart openended heat exchanger units for absorbing heat from a flow of heated coolant passing therethrough, and throttling elements movably mounted across the spaces between adjacent heat exchanger units for throttling a flow of heated coolant passing therethrough whereby the pressure pattern of the flow of heated coolant passing between said heat exchanger units substantially corresponds to the pressure pattern of the flow of heated coolant passing through said heat exchanger units.
