Definitions
- the invention relates to a heat exchanger, the at least one heat exchanger tube and an upstream end tank and a drain side end tank having are arranged opposite to each other and by means of at least one Heat exchanger tube are connected, wherein the heat exchanger tube at its respective insertion in associated receiving openings of the inlet or outgoing end tanks is inserted.
- the heat exchanger is preferably in Motor vehicles z. B. used as a cooler, condenser and / or radiator.
- the Heat exchanger tubes in particular at right angles cut to length heat exchanger tubes with its insertion so far into the inlet and outlet end tank protrude that with flows through the respective end tank with a medium, For example, a gas or a liquid generates a significant pressure drop becomes.
- the heat exchanger tube projects with its insertion end in cross section in the respective end tank, in particular approximately to the middle of the respective end tank into it. As a result, an undisturbed flow of the medium through the high Resistance of the insertion end prevented. Due to the pressure drop must with a lower system efficiency can be expected, which is why a media pump with a must be designed according to higher power.
- DE 43 09 360 A1 relates to a heating heat exchanger for motor vehicles an at least two-row bundle of parallel ribbed heat exchanger tubes, in particular of metal, and with at least one water tank, the one Tube bottom, in particular made of plastic.
- the tube bottom are the Ends of the tubes at one end of the bundle in each case externally and internally in a press fit includes.
- the insert is each as a acting on the flow behavior of the flowing medium in the pipe Element formed. At least a portion of all inserts are each as Throttle element formed.
- the inserts are in the different tubes formed with different geometry such that the pressure loss of the flowing medium in the length range of the inserts a desired pressure drop distribution over the communicating with the water box Tube of the bundle is optimized, which is the flow through the individual tubes of the Bundles compared with a flow at the same geometry of Inserts changed.
- the invention has for its object to provide an improved heat exchanger for To provide, in which the pressure drop by simple means considerably is reduced.
- FIG. 1 shows a heat exchanger 1 with heat exchanger tubes 2.
- the Heat exchanger 1 has an inlet-side end tank 3 and an outlet side End tank 4, which are arranged opposite to each other.
- the respective heat exchanger tube 2 is with its respective Einsteckende 6 in associated receiving openings of the inlet and outlet side End tanks 3 and 4 inserted.
- ribs 7 are arranged in a conventional manner.
- One Medium is fed via an inlet connection 8 to the inlet-side end tank 3.
- the supply of the medium is shown by the arrow 9.
- the Heat exchanger tubes 2 enters the medium in the drain-side end tank 4.
- the Arrow 11 represents the flow of the medium through a drain port 12.
- the Inlet 8 is arranged above the outlet nozzle 12.
- the heat exchanger tube 2 is a flat tube in the preferred embodiment, But also in any other geometric shape, for example, as a round tube or be designed as an oval tube.
- the insertion ends 6 can, for example have widening for pressure drop reduction.
- the receiving openings are to the design of the respective tube geometry and its insertion end customized.
- the connection of the heat exchanger tube 2 with the inflow or drain-side end tank 3 and 4 is produced in a conventional manner. Preferably a solder joint is selected, but also adhesive or Welded joints are possible. Thus, the heat exchanger tube 2 is sufficient sealed to the respective end tank 3 and 4 respectively.
- the heat exchanger tube 2 is made of AlMg. It is also possible that the heat exchanger tube made of other materials such. Copper, brass or Steel exists.
- the end tanks 3 and 4 are made of plastic in a conventional manner or light metals and have common cross sections. By doing preferred embodiment, the end tanks 3 and 4 have a round Cross-section, but these also have a different cross-section can.
- the end tanks 3 and 4 may have composite elements. For example, an embodiment with a metal end plate and a Plastic tank conceivable, but also an embodiment as a sawn pipe is possible. In addition, both the end plate and the end tank made of AlMg be prepared.
- the heat exchanger tube 2 is at its respective insertion end 6 edited so that, for example, a pressure drop of the in the heat exchanger. 2 flowing medium is significantly reduced.
- the heat exchanger tube 2 seen at its Einsteckenden 6 in cross-section in the manner of a Circular section designed cutout 13 on ( Figure 3).
- the cutout 13 is in Cross section seen oval.
- a pressure difference of the medium from the inlet pipe 8 to the outlet nozzle 12 is also significantly reduced. By the reduced Pressure drops can be used with correspondingly lower performance media pumps become.
- the cutout 13 is not shown.
- the cutout 13 is by means of punching or other conventional production methods such as. cut or made saw.
- the cutout 13 is shown only on one side.
- the cutout 13 is also on the hidden side of the Stuck 6 arranged. This results in a, based on the Transverse central axis X-X, on both sides of the insertion end 6 convex curvature of the Inserting 6, each in the direction of the opposite insertion end. 6 the same heat exchanger tube 2 is oriented.
- the spigot 6 is pointed configured transitions 14 of the two convex curvatures.
- the transitions 14 can of course be dulled.
- the heat exchanger 1 can be both vertical and horizontal or to be flowed through in a U-shape.
