Definitions
- the present invention relates to a heat exchanger comprising a number of heat exchanger plates comprising a pressed pattern of ridges and grooves adapted to form flow channels for media to exchange heat flowing through said flow channels, the plates further comprising at least four port openings arranged to allow fluid communication to said flow channels and a skirt extending around the periphery of the heat exchanger plates, said skirt sealing the flow channels.
- a relatively common type of heat exchanger for carbon dioxide applications is the "dual pipe" exchanger, which comprises two parallel pipes, which are interconnected to enable heat transfer between the pipes. Usually, a pipe with a small diameter is used for the high pressure medium, whereas a pipe with a large diameter is used for the low pressure medium.
- Dual pipe heat exchangers have excellent properties concerning capability to withstand pressure, but are inefficient in terms of heat exchanging capability vs. weight.
- CBE Compact Brazed Exchanger
- a CBE generally comprises a number of heat exchanger plates, all of which being provided with a pressed pattern of ridges and grooves and port openings for fluid communication with flow channels formed by interaction between the pressed patterns of ridges and grooves of neighboring plates.
- the pressed patterns of neighboring plates are arranged such that ridges of one plate contact grooves of a neighboring plate.
- the contact points are brazed to one another to provide sufficient strength to the flow channel formed by the patterns of ridges and grooves of neighboring plates.
- the flow channels formed by the interaction between the ridges and grooves are laterally sealed by interacting skirts provided around the circumference of the heat exchanger plates.
- Fig. 1 is a perspective view of a heat exchanger plate according to a first embodiment of the present invention
- Fig. 2 is a plan view of a heat exchanger plate according to a second embodiment of the present invention
- Fig. 3 is a perspective view of a heat exchanger plate according to a third embodiment of the present invention
- Fig. 4 is a perspective view of a heat exchanger manufactured from a number of heat exchanger plates according to the third embodiment
- Fig. 5 is a perspective view of a heat exchanger plate according to a fourth embodiment of the present invention.
- a heat exchanger plate 100 comprises a heat exchanging area 1 10, provided with a pressed pattern (not shown) of ridges and grooves, in a way well known to persons skilled in the art.
- the patterns of ridges and grooves of neighboring plates are adapted to provide flow channels between the plates due to contact between ridges of one plate contacting grooves of its neighboring plate when the plates 100 are stacked onto one another in a way well known by persons skilled in the art.
- the heat exchanger 100 also comprises at least two low pressure port openings 120 and two high pressure openings 130. The port openings are in selective fluid communication with the flow channels formed by the pattern of ridges and grooves in a way to be described below.
- a skirt 140 surrounds the heat exchanging area 1 10 and is arranged such that two skirts of neighboring plates interact to form a seal between such neighboring plates by an overlapping engagement between neighboring skirts, hence sealing the flow channels formed by the pressed pattern of ridges and grooves.
- the high pressure port 130 is placed on a "peninsula" 150 extending out from the heat exchanging area 110.
- the peninsula 150 is closely surrounded by the skirt 140 over an angle ⁇ of about 180 degrees.
- Fig. 2 shows virtually the same embodiment as is shown in Fig, 1, with the exception that fig. 2 shows the skirt 140 being surrounded by a plate portion 160 which is provided with a pressed pattern of ridges and grooves.
- the ridges and grooves 165, 166, respectively, of the plate portion 160 are adapted to contact corresponding ridges and grooves of the plate portion 160 of a neighboring plate, and hence increase the strength of the seal formed by the skirt 140.
- Fig. 3. shows still a further embodiment of a heat exchanger plate 200 according to the present invention.
- a peninsula 210 extends in a direction parallel to a length axis of the heat exchanger plate 200, and a high pressure port 220 is located on such peninsula.
- the skirt 140 closely surrounds the high pressure poit 220 over about 180 degrees.
- a desired number of heat exchanger plates are stacked onto one another. Not all heat exchanger plates 100 or 200 are of the same design, every other plate in the stack is a mirror image of its neighboring plates; by varying the height of the areas surrounding both the high pressure ports and the low pressure ports, it is possible to determine which port opening that shall communicate with each flow channel. This method of determining the fluid communication in a heat exchanger is well known by persons skilled in the art, and will hence not be more thoroughly discussed.
- the entire plate package is subjected to a brazing operation, i.e. the plate package is put into a furnace and heated to a temperature sufficient to melt a brazing material arranged between the plates. After the brazing material has melted, it will concentrate to areas wherein the plates are lying close to one another (the concentration of the brazing material is due to capillary forces). Consequently, the plates will be joined by a brazing connection after the heat exchanger has cooled down sufficiently to allow the brazing material to solidify.
- a heat exchanger 400 comprising a number of heat exchanger plates 200 is shown.
- the skirts 140 form an edge around the circumference of the heat exchanger plates, and it is also very clear how the skirts 140 interact to form a half-pipe like closure around the high pressure port openings 130.
- the half-pipe like closure formed by the skirts 140 around the high pressure port openings 130 gives a very high strength around the port openings; the forces emanating from the surface area of the port will be transferred through the connections between the overlapping skirts.
- the peninsula placement of the high pressure port 130 increases the strength of the port by fact that a large portion of the port opening lies in the vicinity of the skirt 140; as previously described, skirts 140 of neighboring plates will overlap to form a sealed connection between the plates.
- the overlapping skirts will form a "half-pipe" of overlapping skirts.
- Such a half pipe-like array of overlapping skirts has proven to be very strong, it can absorb forces in a much more efficient way than e.g. the contact points between the pressed patterns of the heat exchanging areas.
- a heat exchanger plate according to a further embodiment embodying this feature of the present invention is shown.
- both a high pressure port 300 and a low pressure port 310 are placed on peninsulas 320, 330, respectively, the definition of a peninsula being that the skirts surrounding the plates closely surrounds the port openings over more than 90 degrees.
- the skirt 140 not necessarily must be arranged such that it only surrounds the heat exchanger as a whole; it is also possible to provide any portion of the heat exchanger plates with skirts.
- a skirt could be arranged such that an opening is formed in the heat exchanger; any arrangement wherein plate portions extend in a generally perpendicular direction vis-a-vis a plane of the heat exchanger, and wherein such plate portions of neighboring plates are designed to overlap corresponding plate portions of neighboring plates in a way that has been described above with reference to the skirt 140 are regarded as skirts in the wording of the claims.
