Definitions

  • the invention relates to a heat exchanger, in particular an evaporator for an air conditioning system, with a distribution device which has an inlet and individual channels leading from this inlet to pipes of a heat exchanger block.
  • the inflowing heat exchange medium is distributed as evenly as possible over the tubes of the heat exchange block. This is particularly important in the case of evaporators in air conditioning systems in order to obtain good cooling performance and, above all, uniform cooling of the air flowing through the evaporator.
  • connection box with a cavity of circular cross section, in which a profile body is arranged, which divides the cavity into individual channels that extend helically to the individual tubes .
  • the invention has for its object to provide a heat exchanger of the type mentioned, which has a distribution device which consists of parts that are easy to manufacture and which is simple and in particular also in series production can also be assembled in large quantities with as little effort as possible using automatic machines.
  • the distribution device is assembled from two sheet metal profiles which are connected to one another in a sealing manner and which are provided with connections for the tubes and for embossments forming an inlet tube.
  • Such sheet metal profiles can be produced easily and above all with a high degree of dimensional and tolerance accuracy and then just as easily joined together. This joining takes place by soldering or gluing, the tubes of the heat exchanger block and an inlet pipe then also being inserted and sealed at the same time during the joining. complete soldering takes place.
  • the sheet metal profiles are each provided with a central, half-shell-shaped embossment which form a channel into which a profile body is inserted, which divides the channel into helical individual bodies leading to the connections for the pipes.
  • a profile body as it is known per se (DE 33 11 579 C2), can be inserted between the sheet metal profiles in a simple manner during assembly.
  • the sheet metal profiles have a plate-like or strip-like basic shape and are provided with half-shell-shaped impressions, between which connecting surfaces lying in the plane of the row of tubes are left, in the area of which the sheet metal profiles are sealingly connected to one another. This results in large connecting surfaces, which on the one hand ensure a secure seal, while on the other hand they also bring about a high level of strength with which the sheet metal profiles are held together.
  • the impressions serving as connections for the tubes of the heat exchanger block connect to the central impression with a constriction adapted to the inside diameter of the tubes.
  • At least one of the sheet-metal profiles in the region of the impression forming the channel for the profile body is provided with a projection that prevents the profile body from rotating in a predetermined position.
  • the sheet metal profiles are provided with at least two index holes that are aligned with one another when being joined together. These index holes, which can be punched out in a simple manner during the production of the sheet metal profiles, ensure that the assembly and subsequent connection between the two sheet metal profiles are accurate. They can be attached in a simple manner during the stamping or pressing of the sheet metal profiles, so that there is no significant additional effort.
  • one of the two sheet metal profiles is provided with passages serving as connections for the tubes of the heat exchanger block, and that the other sheet metal profile serves as a cover for the sheet metal profile provided with the passages.
  • a distribution device can also be produced in an inexpensive manner, which enables easy assembly.
  • the starting material is a sheet metal plate of approximately 1.0 mm thickness, from which a strip-shaped object is punched out, which is provided with several embossments, which are described below.
  • the sheet metal profiles (10, 11) have a central, half-shell-shaped indentation (12) which forms a channel which runs in the plane of the ends of a row of tubes (13) which belong to a heat exchanger block.
  • the channel (12) is closed at its end (14).
  • the indentation (15) is preceded by a further indentation (16) which ends in an indentation (17) which is enlarged in radius and serves as a connection into which an inlet pipe (18) is inserted. Conical transitions are formed between the impressions (12, 15 and 16).
  • the channel has a Z-shaped course in the plane of FIG. 1 and a U-shaped course in the plane of FIG. 2, so that the inlet pipe (18) is laterally and vertically offset from the row of pipes is coming.
  • any modifications with regard to the position of the inlet pipe (18) are possible.
  • transverse, also half-shell-shaped impressions (19) branch off from the central impression (12) and serve as connections for the tubes.
  • These impressions (19) have a stepped shape, i.e. they begin at the central embossing (12) with a smaller radius which is adapted to the inside diameter of the tubes (13) and then pass into an outer section with a larger radius which is adapted to the outside diameter of the tubes (13).
  • the step between the sections of the impressions (19) serves as a stop for the tubes (13).
  • These tubes (13) are provided in a manner not shown with transverse ribs, as is common in such heat exchangers.
  • the tubes (13) are part of a preassembled tube / fin package which are connected to one another during the complete soldering.
  • the star-shaped webs of the profile body (20) run in the axial direction helically or helically so that, together with the inner wall of the indentations (12), they divide the channel present in this area into individual channels, each of which runs helically to one of the indentations (19)
  • Each tube (13) of the heat exchanger block is thus assigned a single channel, which begins at the conically enlarged nozzle formed by the impressions (15), into the area of which the profile body (20) protrudes with a beginning that begins at a point.
  • the length of the profile body (20) is adapted to the length of the impressions (12) so that it is fixed in the axial direction.
  • the sheet metal profile (10) is provided in the region of the indentation (12) with an embossed nose (21) which engages between two webs of the profile body and secures it against twisting.
  • All impressions (12, 15, 16, 17 and 19) are each delimited by large-area, flat connecting surfaces with which the two sheet metal profiles (10, 11) are joined tightly opposite one another. This connection takes place after inserting the ends of the tubes (13), the inlet tube (18) and the profile body into the relevant embossments.
  • these connecting surfaces are connected to one another, as are the tubes (13) with the impressions (19), the inlet pipe with the impressions (17) and also the profile body (20) with the impressions (12) by means of soldering.
  • solder plating can also be provided on the tubes (13) and the inlet tube (18).
  • a metallic profile body (20) for example made of an extruded aluminum profile, is then expediently provided.
  • the sheet metal profiles (10, 11) are connected to one another and to the tubes (13) and the inlet tube (18) by means of an adhesive.
  • the profile body (20) can also be produced as a molded plastic part. In all cases, the large-area connection surfaces offer high strength and also very good tightness.
  • the parting line between the two sheet metal profiles (10, 11) runs in the common plane of the tubes (13)
  • the parting line between a sheet profile (22) and a further sheet profile (23) transverse to this common plane of the tubes of the heat exchanger block.
  • the sheet-metal profile which has a half-shell-shaped central indentation (12 ') for the profile body (20) is provided with passages (24) into which the ends of the tubes (13) of a heat exchanger block are inserted.
  • the ends of the tubes (13) are inserted against the ribs of the profile body (20).
  • the sheet metal profile (22) is provided on its edges with a stepped bend (25) in which the sheet metal profile (23), which serves only as a cover, is inserted with its edges.
  • the sheet metal profiles (22, 23) are soldered to the tubes (13), the profile body (20) and an inlet pipe, not shown.
  • the tubes (13) with fins (not shown) form a heat exchanger block, a so-called tube fin block.
  • the ends of the tubes (13), not shown, are received by a collecting device, which can also be formed from two sheet metal profiles in accordance with the distribution device. In most cases, this collection device will have the same structure as the distribution device. In some cases, however, it will be possible to simplify the collecting device somewhat and, for example, to dispense with the profile body (20).
  • the sheet metal profiles (10, 11) are provided in the area of their connecting surfaces with a plurality of index holes (26) which are expediently stamped in when the sheet metal profiles (10, 11) are formed.
  • index holes (26) allow the two sheet metal profiles (10, 11) to be assembled exactly during assembly, for which purpose the index holes (26) of the two sheet metal profiles are brought into alignment one above the other. This can be done, for example, using the spikes of an assembly device.
