Definitions

  • the present invention relates, in general, to a plate heat exchanger and, more particularly, to a plate heat exchanger which can increase the fluidity of a fluid, thereby realizing improved heat exchange efficiency.
  • a heat exchanger is a device for transferring heat from a higher temperature fluid to a lower temperature fluid through a heat transfer wall, and is used in an air conditioning system, a transmission oil cooler, etc. of an automobile. To be accommodated in a limited space in which the heat exchanger is installed, it is required to realize compactness of the heat exchanger and, accordingly, a plate heat exchanger has been widely used.
  • the plate heat exchanger includes a plurality of heat exchange elements that are stacked to define a flow channel between neighboring plates of the elements.
  • the flow channel includes at least two flow channels through which different heat exchange medium can flow.
  • the different heat exchange medium exchange heat with each other through the heat exchange elements when the medium pass through the respective flow channels.
  • each of the respective plates of the heat exchange elements has an inlet port and an outlet port in opposite ends thereof, wherein the inlet ports and the outlet ports of the respective plates communicate with each other.
  • An inlet cap and an outlet cap are mounted to the inlet and outlet ports of the uppermost plate by brazing, etc.
  • a heat exchange element of a conventional plate heat exchanger is fabricated by assembling a pair of plates 1 and 2 with each other.

  • a fluid in the flow channel flows along the grooves 1a and 2a of the respective plates 1 and 2, so that the fluid flows in an diagonal direction. Therefore, the flow of fluid may easily stagnate on the depressed edges 1c and 2c around the through holes 1b and 2b, so that the conventional plate heat exchanger excessively reduces the fluidity of the fluid and, accordingly, reduces the heat exchange efficiency.
  • the present invention has been made keeping in mind the above problems occurring in the related art, and is intended to provide a plate heat exchanger which can increase the fluidity of a fluid, thereby realizing improved heat exchange efficiency.

Further, in the heat exchange element 10, the upper flow grooves 11bof the upper plate 11 intersect with the lower flow grooves 12b of the lower plate 12, thereby defining the first flow channel 18 having an intersecting structure. Therefore, when the first fluid is introduced from the inlet port 43 into the first flow channel 18, the first fluid flows zigzag both through the upper flow grooves 11b of the upper plate 11 and through the lower flow grooves 12b of the lower plate 12 prior to being discharged through the outlet port 44.

  • the upper flow grooves 11b of the upper plate 11 are formed on the rear surfaces of the bulging parts 13a of the wave structure 13, so that the bulging parts 13a and the upper flow grooves 11b are oriented in the same direction and, accordingly, the upper subsidiary groove 63 intersects with the bulging parts 13a at the predetermined angle of intersection. Therefore, in the area around each of the upper flanges 23 of the upper plate 11, the first fluid can flow in main flow directions (the directions designated by arrow K) in which the fluid flows along the upper flow grooves 11b and, at the same time, can flow in at least one subsidiary flow direction (the direction designated by arrow U) in which the fluid flows along at least one upper subsidiary groove 63.

Therefore, the present invention can prevent stagnation of the first fluid in the areas and, accordingly, can allow the fluid to smoothly and constantly flow for the whole length of the respective plates 11 and 12. That is, the present invention increases the fluidity of the first fluid and, accordingly, realizes improved heat exchange efficiency.
  • a second flow channel 28 through which a second fluid, such as cooling water, passes is defined between the stacked heat exchange elements 10.
