Definitions
- the invention relates to a heat exchanger of the desk type, having a core made of planparallelly and mutually in distance arranged plates, defining passages for heat exchanging fluids, the core being compressed between end panels by means of tie rods.
- Heat exchangers of the known construction have a core consisting of plates compressed between rigid end panels by means of tie rods fixing their position and a rigidity of the whole assembly. Individual adjacent plates are mutually separated by spacing elements of various shapes, the elements defining pluralities of parallelly arranged channels for which it applies that channels in one layer are perpendicular to the channels in adjoining layers. Such embodiments with end panels in direct contact with the plate core are satisfactory for low temperature applications showing only low level of
- a heat exchanger of the desk type having a core made of planparallelly and mutually in distance arranged plates, defining passages for heat exchanging fluids, the core being compressed between end panels by means of tie rods in an embodiment in accordance with the present invention comprising spacers filled with insulation, the spacer being arranged between the core and each of the end panels.
- the end panels are sprung away from the core, advantageously by means of elastic elements located between the end panels and the spacers and/or located on the tie rods.
- the spacer comprises a plurality of crossbars and in a preferred embodiment the the spacer is of a honeycomb construction.
- the spacer further provides for uniform distribution of the temperature gradient between the core and the end panel. It results in negligible temperature difference between- the spacer and the adjoining core plate and the end plate respectively, which practically eliminates friction and fretting at contact surfaces of these parts. It is a further object of the invention to achieve a uniform distribution of compressiwe forces applied upon the core by the end panels which results in lower mechanical stress of tie rods and the core as well.
- FIG. 1 illustrates completely assembled heat exchanger.
- Fig. 2 shows the same in partially dismantled setup
- Fig- 3 presents particular parts of the heat exchanger
- Fig. 4 offers details of the core according to the Fig. 3-
- the heat exchanger similarly to those already existing ones, comprises plate core 1, which is compressed between two end panels 2 by means of tie rods.
- the tie rods are provided for by bolts 3 passing through sleeves 4 which are distributed along end panel 2 edges.
- the position of end plates 2 and pressure applied by them upon the core 1 are secured by nuts 5-
- Each end panel 2 is on its outside surface provided with crossbars 6-
- the core 1 consists of flat plates 7, arranged in a planparallel layout and mutually separated by spacing elements 8 being set apart at regular intervals.
- the spacing elements 8 define intermediate space between adjoining plates 7, thus allowing for flow of heat-exchanging fluids and preventing excessive mechanical stress and the plate 7 deformation.
- the edge bars 9 located along the plate 7 edges are well sealed against the adjoining plates 7, advantageously by welds, thus providing for enclosure of the inner core 1 space.
- Distribution heads 14 provide for particular inlets and outlets of heat-exchanging fluids into and out of the intermediate spaces of the core 1 plates 7.
- spacers IO which are of a honeycomb construction. The said spacers IO are placed between the core 1 and respective end plates 2.
- Space between spacing bars 11 of the spacers IO is filled with thermal insulation 12-
- the spacers IO allow for uniform distribution of pressure forces applied upon the core 1 by the end panels 2 and for uniform distribution of a thermal gradient showing maximum values at the core 1 surface and minimum val es at the outer surface of the end panels 2.
- the temperature of the spacers IO and the core 1 in their contact area is nearly the same for both elements and their thermal expansion being virtually equal is thus accompanied by very little or no friction. This applies similarly for the spacers IO and the end panels 2.
- Uniform temperature gradient existing across the spacer IO provides for low thermal and mechanical stress not only of these parts but also of adjoining core 1 and the end plate 2.
- the core 1 can be sprung away from the end panels 2 also by resilient elements placed between the end panels 2 and the spacer IO- Bolts 3 or any similar tying rods can be attached to end panels 2 also by means of welding.
- the present invention is designed for any application of heat exchangers operating at high temperatures and pressures-
