Definitions

  • the object of the present invention is to provide improved means for sealing the high pressure passages of a heat exchanger unit of the loosely stacked component type described above.
  • the invention is characterized by the provisionin a heat exchanger unit having spacer strips each provided with a first surface bonded to a heat exchanger plate-of auxiliary means sealing the opposed second surfaces of those outermost spacer strips which lie between alternate pairs of plates.
  • the auxiliary sealing means comprises a continuous layer of a suitable adhesive such as glue.
  • the sealing means comprise strips of a resilient compressible material, such as rubber, that are compressedbetween said alternate pairs of plates inter-.
  • the heat exchanger unit consists of a plurality of loosely stacked components rather than a unitary assemblage, theunit may readily be assembled and mounted within the heat exchanger housing.
  • FIGS. 1 and 2 are perspective and exploded views, respectively, of the heat exchanger unit of the prior art
  • FIGS. 3 and 4 are exploded views of two embodiments of the heat exchanger unit of the present invention.
  • F168. 5 and 6 are elevational and end views, respectively, of another modification of the heat exchanger unit using resilient sealing strips. l 1
  • the heat exchanger unit consists of a stack of spaced, parallel plates 11,12, 13, 14, 15, 16 and 17 betweenwhich are arranged spacerstrips 18, 19, 28, 21, 22. and 23. Both the plates and .thespacer strips are formed from a brittle silicate, such as glass Spacer strips '18, 2d and 22 are arranged to define parallel passages between alternate pairs of plates for conducting a first heat exchanging fluid M in a given direction through the unit.
  • Spacer strips 19, 21 and 23 are arranged to define passages between the remaining pairs of plates through which a second heat exchanging fluid M is directed normal to the direction of fluid M
  • the heat exchanger unit is so mounted in a housing, not shown, that an axial compressive force p is developed to press the'elements of the stack into tight sealing engagement.
  • This compressive force maybe developed by auxiliary clamping means or, when the stack is mounted vertically, by the respective weights of the elements together with additional loading forces applied to the upper plate of the stack.
  • FIG. 2 presents the drawback that the pressure forces may lift (or deform by fiexure) portions of one or more of the plates off of the outer spacer strips against which they are pressed, thus causing undesirable leakage of the higher pressure medium into the flow stream of the lower pressure medium.
  • fluid Mi has a greater pressure than that of fluid M
  • the outermost high pressure passage spacer strips and 22" are bonded to both of the plates between which they are arranged, and the low pressure spacer strips 19" and 21" are bonded only to plates 13" and 15", respectively.
  • the innermost spacer strips Zil" and 22" need only be bonded to plates 14 and 16', respectively.
  • the means for bonding the spacer strips to the plates consists preferably of uniform continuous layers of an adhesive such as glue. 7
  • sealing of the high pressure fluid passages may be achieved by the use of compressed, resilient sealing strips as shown in the embodiment of FIGS. 5 and 6.
  • the spacer strips 32 that define the high pressure passages are bonded to plate 31 and the spacer strips 34 that define the low pressure passages are bonded to plate 33.
  • Cylindrical resilient sealing strips are positioned between and contiguous with the outermost spacer strips 32.-
  • Each sealing strip is formed of a resilient compressible material such as rubber, and has-in the normal uncompressed state-a diameter that is greater than the spacing height of spacer strips 32. Consequently, when plates 31 and 33 are pressed toward each other to cause engagement between spacer strips 32 and plate 33, sealing strips 35 are compressed into tight sealing engagement with plates 31 and 33 and the outermost spacer strips 32. Furthermore, upon flow of high pressure fluid through the passages defined by strips 32, sealing strips 35 are deformed outwardly'against the outermost spacer strips 32 to tightly seal the unbonded surface contact joint between the outermost spacer strips and plate 33.
  • sealing strips having non-circular cross-sectional configurations may be used equally as Well, the only limitation being that the thickness of the sealing strips is greater than the spacing dimension of the spacer strips so that, upon assembly of the 'stack, said sealing strips will be compressed between the plates.
  • sealing of the innermost spacer strips that define the high pressure passages is not as critical as the sealing of the outermost spacer strips, since leakage of fluid from one high pressure passage to CHARLES 4 another does not adversely affect the operation of the heat exchanger.
  • the thicknesses of the platesand strips have been greatly exaggerated. In actual practice the elements of the heat exchanger unit are rather thin and, owing to the large surface dimensions of the plates, are extremely brittle.
  • a heat exchanger unit comprising i a first horizontal massive thick brittle plate
  • first spacer strips each of which is bonded in fluid-tight sealing engagement with the upper surface of said first plate, the outermost pair of said first spacer strips being adjacent the corresponding edges of said first plate;
  • third horizontal plate means in contiguous unbonded engagement with the upper surfaces of said second spacer strips and cooperating with said second strips and said second plate to define parallel low-pressure passages extending normal to the axes of said high pressure passages, whereby when a plurality of the heat exchanger unit components are stacked upon each other, the weight of the components eifects sealing contact between the contiguous unbonded surfaces thereof.
