Definitions
- the invention relates to a heat exchanger, in particular gas cooler, having at least one longitudinally extending collecting box, which comprises a bottom and a lid and at least two in cross-section substantially circular longitudinal channels, which by at least one of the bottom and / or lid formed
- the longitudinal partition wall are at least partially spaced from each other, wherein the bottom of at least one of its longitudinally extending edge regions has a shelf with which the bottom overlaps a longitudinally extending edge region of the lid outside or wherein the lid on at least one of its longitudinally extending edge regions Board has, with which the lid engages over a longitudinal edge region of the bottom outside.
- a collection box in which the board is formed by separated lobes. Again, the board is bent or folded after applying the lid to the ground to fix both parts together. However, the joining forces between the bottom and the lid are low due to material stripping and elastic deformation of the board.
- the present invention has for its object to provide a heat exchanger, which builds simple and expedient in a safe joining and is inexpensive to produce.
- a heat exchanger in which the respective board in the longitudinal direction has a plurality of caulking, by which it is deformed in the region of each individual caulking in the direction of the Sammelkastehmitte and determines the bottom and the lid against each other.
- the lid and base are stamped from a sheet metal blank and each have in cross-section substantially a w-shape or ⁇ -shape. Due to this shape, the bottom and lid touch in their outer areas and in their centers, whereby the longitudinal partition wall is formed.
- the two opposite shelves can be angled outwardly in the areas in which they have no caulking. However, it is preferred that the two shelves in the areas in where they have no caulking, run parallel to each other. It is particularly advantageous that a powerful joining of lid and bottom is achieved with low material usage by the large number of caulking.
- the plurality of caulking is arranged symmetrically with respect to the collection box center.
- the combination of cover and bottom has a symmetrical force curve, which increases the quality of the joint.
- two adjacent caulkings in the longitudinal direction equal to ⁇ or differing widths.
- the caulkings arranged in the longitudinal direction have the same or different distance from one another. In areas of the collecting tank, where due to the expected load, a greater addition of the header tank is required, this can be easily ensured by increasing the width of the caulking or by the number of caulking within the relevant area.
- the geometry of the individual caulking is basically arbitrary. Shares, angled or round versions are possible.
- a single caulking has a width of 0.5-6 mm, in particular 0.75-5 mm, in particular 1-4 mm. As a result, a punctual caulking is achieved, whereby the force required for producing the caulking is reduced.
- one or more caulking forms a receptacle for at least one connecting piece, in particular flange or holder.
- the connecting piece in particular flange or holder, For example, it can be hooked into the caulking.
- the connection piece is clamped by the caulking.
- the bottom and the lid are soldered together.
- the heat exchanger can withstand high pressures, and be used, for example, in a CO2 refrigerant cycle.
- the heat exchanger has a multiplicity of flat tubes forming a Wäimeübertragungsf, wherein the flat tubes tube ends and the bottom of the number of flat tubes has corresponding openings for receiving the tube ends.
- the shelf of the floor is higher than the outer edge of the lid or the board of the lid is higher than the outer edge of the floor.
- the board of the bottom engages behind the lid in the area of caulking or the board, the lid of the lid in the area of caulking.
- the height of the shelf of the floor over the. Edge of the lid or the height of the shelf of the lid over the edge of the bottom 0.5 - 4 mm, in particular 0.75 - 3 mm, in particular 1 - 2.5 mm, in particular 1-1.5 mm.
- an embodiment according to the invention is preferred in which the caulkings in the corner regions form a positioning device in the longitudinal direction for the collecting box.
- Figure 1 is a perspective view of a header tank of a heat exchanger according to the invention.
- Figure 2 is a side view of the collection box of Figure 1;
- Figure 3 is a plan view of the collection box of Figure 1;
- Figure 4 is a sectional view taken along the section l-l of Figure 3;
- FIG. 5 shows a sectional view along the section H-II according to FIG. 3,
- the figures show an assembly of a total provided with the reference numeral 2 heat exchanger, in particular gas cooler.
- the heat exchanger 2 comprises a collecting box 6 which is extended in a longitudinal direction 4 and is formed from a base 8 and a cover 10.
- the base 8 and cover 10 are stamped from a sheet metal blank and have a w- or ⁇ -shaped cross section Lids 10 touch each other in their edge regions 12 and in their centers and form there an at least almost closed longitudinal partition wall 14 for longitudinal channels 16 extended in the longitudinal direction 4 (FIGS. 4 and 5).
- the bottom 8 at its longitudinally 4 extending edge regions 12, a shelf 18 which engages over the lid 10 outside.
- the board 18 has a plurality of caulking 20, on which the board 18 of the bottom 8 is deformed in the direction of the center of the collecting tank 6 and at the De- disgust 10 is applied, whereby the lid 10 and the bottom 8 are fixed against each other.
- Figures 1, 2 and 3 show the collection box 6 from different views.
- the ribs 18 are parallel to each other and are higher than the outer edge 22 of the lid 10, the caulking 20 are applied to the outer edge 22 of the lid 10, so that the bottom 8 engages behind the lid 10 in the caulking 20 perpendicular to the longitudinal direction 4 ,
- the caulking 20 are arranged symmetrically to the center of the collecting tank 6 and have substantially the same width.
- the caulking 20 have a geometry that has predominantly straight and angled portions.
- a fitting 24 is connected to the collecting box 6 via a receptacle 26 formed by one of the caulking 20.
- the distance between two adjacent in the longitudinal direction 4 caulking 20 is less than in areas where no connection piece 24 is received.
- On the side facing away from the shelves 18 of the bottom 8 openings 28 are arranged, in which a plurality of heat transfer surface forming flat tubes (not shown) can be inserted with their tube ends,
- the bottom 8 and the lid 1Q are punched from a sheet metal blank and are w- or ⁇ -shaped embossed.
- To join both parts of the lid 10 is disposed within the bottom 8 and 12 overlapped by this at its edge 12 from outside through the shelves 18.
- the cover 10 and the bottom 8 touch each other in their middle and thereby form the longitudinal separation. wall 14, which spaced the two longitudinal channels 16 from each other.
- bottom 8 and Decket 10 are pressed together and put together.
- the shelf 18 of the bottom ⁇ is higher than the outer edge 22 of the top 10 and extends in the areas where there is no caulking 20 parallel to the opposite board 18. In this way, the caulking 20 engages behind the lid 10 and presses it against the ground 8.
- FIG. 5 shows a section along the line INI according to FIG. 3, in which a connecting piece 24 is arranged at the level of a caulking 20 formed as a receptacle 26.
- the connector 24 rests on the one hand on the outer edge 22 of the lid 10 and is clamped by the caulking 20 since «lent so that it is fixed to the collecting box 6.
