  • the first and the second heat exchange fluid is uniformly distributed to the first and the second fluid flow passages "A" and "B" respectively.
  • the pressure drop of first fluid, for example, refrigerant across the first inlet and out is increased, similarly, the pressure drop of second fluid, for example, the coolant is also increased. Accordingly, more time is available for the heat exchange between the first fluid and the second fluid. Further, the mass flow rate of coolant and the refrigerant is increased. Accordingly, the cooling power of the heat exchanger configured with the plates in accordance with the present invention is higher than the heat exchanger configured with conventional plates.
  • a heat exchanger 100 is disclosed in accordance with an embodiment of the present invention.
  • the heat exchanger 100 includes a plurality of plates 10, 20, particularly, a first set of plates 10 and a second set of plates 20, a first inlet and outlet and a second inlet and outlet.
  • FIG. 4 illustrates an isometric view of a heat exchanger, particularly, a water-cooled condenser 100 configured by assembling a plurality of plates, at least one plate being configured with blocking element 14a.
  • the blocking element 14a extends from at least one of the corrugations 14 to the corresponding peripheral rib 12, in order to block the gap between the corrugation 14 and the corresponding peripheral rib 12. Referring to FIG.
  • each plate 10, 20 includes a peripheral rib 12, 22, a plurality of corrugations 14, 24, a first set of inlet and outlet holes 16a, 26a and 16b, 26b, a second set of inlet and outlet holes 18a, 28a and 18b, 28b.
  • the peripheral rib 12, 22 defines the boundary of the plate 10, 20.
  • the corrugations 14, 24 formed on the plate 10, 20 in conjunction with corrugations 14, 24 on adjacent overlapping plate 10, 20 define first fluid flow passages "A” and second fluid flow passages "B" on opposite sides of the plate 10, 20, the second fluid flow passages "B” being adjacent to the first fluid flow passages "A".
  • the first inlet and outlet is defined by the first set of inlet and outlet holes 16a, 26a and 16b, 26b formed on the corresponding plate 10, 20.
  • the first inlet and outlet is in fluid communication with the first fluid flow passages "A” for ingress and egress of first fluid with respect to the first fluid passages "A”.
  • the second inlet and outlet is defined by the second set of inlet and outlet holes 18a, 28a and 18b, 28b.
  • the second inlet and outlet is in fluid communication with the second fluid flow passages "B” for ingress and egress of second fluid with respect to the second fluid passages "B"
  • the first inlet and outlet is defined by aligning a first set of inlet and outlet holes 16a, 26a and 16b, 26b formed on the respective adjacent plates 10 and 20. More specifically, the first set of inlet and outlet holes 16a and 16b formed on the first set of plates 10 are arranged alternatively with respect to the first set of inlet and outlet holes 26a and 26b formed on the second set of plates 20 to define the first inlet and outlet.
  • the second inlet and outlet is defined by aligning the second set of inlet and outlet holes 18a, 28a and 18b, 28b formed on the respective adjacent plates 10 and 20.
  • the second set of inlet and outlet holes 18a and 18b formed on the first set of plates 10 are arranged alternatively with respect to the second set of inlet and outlet holes 28a and 28b formed on the second set of plates 20 to define the first inlet and outlet.
