  • There are the flat tubes by means of an intermediate floor or Support comb is kept at a distance on each side of the pipe block.
  • the pipes enter through through openings through the intermediate floors or the support combs and open open at the end in laterally adjoining, box-shaped, as Connection channels serving distribution or collecting channels.
  • a tube block heat exchanger according to the preamble of claim 1 is e.g. known from DE-3 8 10 131-C.
  • the invention is a technical problem of providing a tube block heat exchanger of the aforementioned Type based, which is comparatively easy to manufacture and has at least two separate fluid circuits.
  • the invention solves this problem by providing it a tube block heat exchanger with the features of the claim 1.
  • This heat exchanger has a comparative easy to manufacture structure from individual, spaced tubes lying side by side and sealed at the ends as well as spacer elements between two neighboring Pipe end areas are introduced to the desired spaces to form between the tubes.
  • the necessary Connection channels on the pipe block cross sides are through respective Cross openings formed in the end areas of the pipes and in the spacers with the exception of the separation spacers are provided.
  • the height in the tube block is opposite on each side of the tube block in a technically simple manner two or more separate connection channels are formed.
  • the Pipe block is thereby in successive pipe block sections divided, which flows through several fluids separately can be.
  • Such a heat exchanger can for example for the simultaneous cooling of Engine oil on the one hand and gear oil on the other hand by means of air be used in a motor vehicle. It is only to fix a single radiator block in the vehicle, which without can also be designed as a large area cooler.
  • U-shaped Spacer shoes are provided, each of which has an associated one Grips pipe end area, with adjacent spacers placed in contact and firmly together are connected.
  • the spacers which keep adjacent pipes at a distance from each other connected halves of two successive spacer shoes educated.
  • the separation spacer elements are thereby realizes that associated, opposite one another at the same height Spacer halves not with a continuous Cross opening are provided.
  • This heat exchanger construction allows the insertion of the separation spacer elements very flexibly at any desired height of the Pipe block, so that the pipe block in its overall dimensions, especially the number of tubes used, as also with regard to its division into fluid-separated ones Pipe block sections in the production without major Additional effort optimal for the respective application can be coordinated.
  • heat exchanger are the separation spacers on their exposed ones Outside areas designed differently than the other spacer elements, and in such a way that this is from a corresponding Sensor technology can be detected. This way is finished Pipe block heat exchanger can be quickly determined where there are separation spacers are located.

  • the separation spacer shoes (5a, 5b) differ from the remaining spacer shoes (5) in that they only on one (5c) of their two halves (5c, 5d) are provided with a transverse opening are formed while the other half (5d) is closed is like this for one (5b) of the two separation spacers can be seen in the detailed view of FIG. 3 is.
  • the two closed halves (5d) lie here two separation spacer shoes (5a, 5b) within the same Gap (2a) between two adjacent flat tubes. So that will a division of the connection channel structure in a simple manner each pipe transverse side in two separate connection channels (9a, 9b) achieved, as shown in Fig. 3 for a pipe transverse side are shown.
