Abstract
A plate heat exchanger includes a case assembly and a plurality of primary flow channel assemblies. The case assembly includes first and second side panels and first and second end plates mounted to the ends of the side plates. Each of the end plates has alternating slots, and ribs extending transversely between the laterally extending edges of the end plate, with the slots of the first end plate and corresponding slots of the second end plate defining multiple pairs of slots. Each primary flow channel assembly includes laterally spaced first and second heat exchange plates, with the inner surfaces of the heat exchange plates forming a longitudinally extending primary flow passage. One of the primary flow channel assemblies is associated with each pair of slots with a first end portion of the flow channel assembly mounted in the slot of the first end plate and the second end portion of the flow channel assembly mounted in the corresponding slot of the second end plate. Transversely extending secondary flow passages are formed between the outer surfaces of the heat exchange plates of adjacent primary flow channel assemblies.
Description
- This invention relates generally to recuperative heat exchangers. More particularly, the present invention relates to recuperative heat exchangers having plate structures adapted to transfer heat from one fluid to another through the surface of the plate.
- Recuperative heat exchangers are known in which a plurality of plates of relatively thin material are stacked in face-to-face arrangement to define fluid passages therebetween for separate flow of primary and secondary fluids in the heat exchange relation. A thin plate type of heat exchanger has been generally very difficult to manufacture, due to the many welding and bonding operations required, and difficult to achieve a strong structure because of the thinness of the plate material. Typically, the heat transfer plates are stacked horizontally on the shop floor and either welded or clamped to form a core having alternating primary and secondary flow paths. After assembly of the core is completed, a casing is constructed around it. Then the gaps between the casing and the core are closed using one of numerous traditional sealing designs. These seals function to prevent leakage between the primary and secondary sides of the heat exchanger.
- There are several problems with this traditional method of manufacture. First, the construction and manufacturing of the traditional sealing systems is labor intensive. The core and the casing experience differential thermal growth in all three dimensions. Such differential thermal growth commonly results in failure of the seals, since the seals are conventionally fixed to both the core and the casing. Three of the four corners of the core generally have an irregular shape due to variances in the plate dimensions. These corners provide a poor surface for seals to contact and/or a difficult surface to interface with other parts. Traditionally, the plates are not thick enough to prevent deformation when stacked horizontally. Spacing devices, such as pins, are required to maintain the plate-to-plate distances during stack-up. These pins account for unnecessary assembly man-hours.
- Briefly stated, the invention in a preferred form is an integrated core/casing plate heat exchanger which comprises a case assembly and a plurality of primary flow channel assemblies. The case assembly includes first and second side panels, each of which has longitudinally extending first and second edges and first and second ends. A first end plate is mounted to the first ends of the first and second side plates and a second end plate is mounted to the second ends of the first and second side panels. Each of the end plates having laterally extending first and second edges and first and second sides. The end plates have multiple slots, with each of the slots being separated from an adjacent slot by a rib. The slots and the ribs of each plate extending transversely between the laterally extending edges of the end plate. The second end plate has a corresponding slot and rib for each slot and rib of the first end plate, with the slots of the first end plate and the corresponding slots of the second end plate each defining a pair of slots. Each primary flow channel assembly includes laterally spaced first and second heat exchange plates. The inner surfaces of the first and second heat exchange plates form a longitudinally extending primary flow passage. One of the primary flow channel assemblies is associated with each pair of slots with a first end portion of the flow channel assembly mounted in the slot of the first end plate and the second end portion of the flow channel assembly mounted in the corresponding slot of the second end plate. The outer surfaces of the heat exchange plates of one primary flow channel assembly forming transversely extending secondary flow passages with the outer surfaces of the heat exchange plates of adjacent primary flow channel assemblies.
- Each side panel includes a sheet member and multiple stiffening members, with the stiffening members being mounted to the outer surface of the sheet member. The stiffening members include multiple transverse stiffening members and multiple longitudinal stiffening members. The inner surface of the sheet member of each side panel defines a transversely extending, secondary flow passage with the outer surface of the heat exchange plate of an adjacent primary flow channel.
- The heat exchanger further comprises first and second edge flange assemblies mounted to the first and second edges of the side panels and the first and second edges of the end plates. First and second end flange assemblies are mounted to the first and second ends of the side panels and/or the outer faces of the first and second end plates.
- It is an object of the invention to provide a plate heat exchanger which does not require seals between core and the sides of the heat exchanger.
