Definitions
- the present invention relates to a heat exchanger having at least two header tanks, which are fluidly connected to one another by means of a plurality of pipes, and a porous metal structure at least partially surrounding the pipes, wherein the heat exchanger has a plate-like shape with a front side and a rear side.
- Such heat exchangers are frequently used for cooling fluids of a machine, for example an internal combustion engine.
- the fluid to be cooled flows into one of the collecting tanks and passes through the many pipes to an opposite collecting tank.
- the tubes are at least partially surrounded by a porous metal structure. Air can flow through the heat exchanger transversely to its extension plane and thus temper the fluid in the tubes, in particular cool it.
- the generic EP 1 511 969 B1 discloses a heat exchanger having two header tanks, which are fluidly interconnected by means of a plurality of tubes, and a porous metal structure at least partially surrounding the tubes, the heat exchanger having a plate-like shape with a front side and a rear side.
- the disadvantage is that the coating of the individual tubes with the porous metal structure represents a high procedural expense.
- EP 1 553 379 A1 shows a heat exchanger with a plurality of flat tubes, between which a porous metal structure is arranged. On the front and the back of the heat exchanger are the tubes open, why damage, for example by rockfall, is easily possible here.
- Object of the present invention is therefore to provide a simple to manufacture and robust heat exchanger.
- a vehicle with a heat exchanger according to the invention is claimed in claim 8.
- a heat exchanger has at least two header tanks fluidly interconnected by a plurality of pipes, and a porous metal structure at least partially surrounding the pipes, the heat exchanger having a plate-like shape with a front side and a rear side, and wherein the metal structure is formed by a plurality of sipes each held between two adjacent tubes and extending over at least one adjacent tube on at least one side of the heat exchanger.
- the porous metal structure By forming the porous metal structure, with which the tubes of the heat exchanger are at least partially surrounded, of a plurality of (identical) lamellae held between two adjacent tubes and extending on at least one side of the heat exchanger over at least one of the adjacent tubes,
- the tubes can be provided in a very simple and cost-effective manner with a greatly enlarged surface, which also protects against damage from the outside.
- the lamellae form on the at least one side of the heat exchanger, on which they extend over the adjacent tube, a preferably closed cover surface in front of the tubes, which keeps particles flowing in with the air from the sensitive tubes.
- Suitable metal structures include foams, nonwovens and fine metal mesh structures.
- the slats each extend on the front over an adjacent tube. If the air flows on the front side of the heat exchanger and out again on the rear side, it is sufficient to let the slats extend over the pipes only on the front side, because only here a significant damage potential exists.
- the slats are each formed in an L-shape.
- the L-shaped sipes have a base part held by the adjacent tubes and a leg part extending over one of the adjacent tubes.
- the front of the heat exchanger is anodized.
- the coating of the leg portions of the slats with hard anodizing additionally increases the resistance of the heat exchanger and can also produce a pleasing appearance through the use of different colors of the anodized.
- the slats are made of an aluminum alloy.
- Aluminum is particularly well suited because it has a low melting point, is comparatively light and inexpensive.
- the aluminum alloy is foamed. A metal foam is particularly easy to bring in the desired lamella shape.
- the tubes are designed as flat tubes.
- Flat tubes are particularly well suited to permanently fix the lamellae between them.
- the lamellae can also be connected to the tubes with a material fit.
- a vehicle has at least one heat exchanger according to the invention, which in a particularly preferred embodiment can be supplied with air at the front in the installed state.
- the heat exchanger serves, for example, as the main radiator for an internal combustion engine or as an air conditioning condenser. This is usually arranged on a vehicle front behind a decorative grille. The impacting particles during travel are safely trapped by the metal structure.
- Fig. 1 is a perspective view of a heat exchanger
- Fig. 2 is a sectional view of a heat exchanger.
- a heat exchanger 1 has two mutually opposite collecting tanks 2, which are fluidly connected by means of several (not visible here) pipes 3, so that in the one collecting tank 2, a fluid can enter and passes through the tubes 3 to the other collection box 2 to leave the heat exchanger 1 there again.
- the tubes 3 are surrounded by a porous metal structure 4, which is formed by a plurality of fins 5.
- the slats 5 are made of a metal foam and have an L-shaped configuration with a (not visible in the present case) base 5a and a leg portion 5b, which can be held with the base part 5a between two adjacent tubes 3 and the leg portion 5b on the front 1a of the heat exchanger 1 extends protectively over in each case one of the adjacent tubes 3.
- the composite of tubes 3 and fins 5 is shown again in section.
- Two adjacent tubes 3 each hold the base part 5a of a lamella 5, so that the leg part 5b on the front side 1a can extend over one of the adjacent tubes 3.
- the lamellae 5 form in combination the protective metal structure 4.
- the leg portions 5b may be coated to further increase the protective effect with a hard anodized.
- the tubes 3 are partially free. When installed, the air flows through the heat exchanger 1 from the front side 1a to the rear side 1b thereof.
