- Figure 15 is a section through an embodiment of a flat tube.
- FIG. 1 shows a heat exchanger 1, in particular an evaporator, in a perspective view.
- the evaporator 1 has a tube-fin block 2 with flat tubes 3 and arranged between the flat tubes ribs 4.
- the flat tubes 3 are fluidly connected at its two opposite ends with the manifolds 5 and 6, wherein the upper header box 5 consists of two chambers 7.8 , wherein the chamber 7 is the inlet-side chamber, which is connected to an inlet connection pipe 9, wherein the chamber 8 is the outlet chamber, which is connected to an outlet connection pipe 10.
- the lower collection box 6 advantageously has at least one chamber which effects a deflection in the depth.
- the inlet port is preferably located laterally on the short side of the header tank and preferably on the leeward side of the heat exchanger.
- the outlet port is preferably at a frontal long side of the collecting tank arranged and preferably on the windward side of the heat exchanger,
- FIG. 2 shows a section through the tubular rib block 2 of FIG. 1, wherein the flat tubes 3 and the corrugated ribs 4 are arranged alternately next to one another.
- the flat tubes 3 are shown in section, so that the fluid, which flows through the flat tube 3, flows quasi perpendicular to the plane through the tubes.
- the corrugated fins are shown only schematically, wherein the corrugated fins are traversed quasi-parallel to the plane of air.
- FIG. 3a shows a flat tube 20 in section, wherein the flat tube of two opposing first and second side walls 21, 22 and two opposing third and fourth side walls 23, 24, wherein the third and fourth side walls 23, 24, the first and second Side walls 21, 22 connect together.
- the side 24 connects the fourth side as the two first and second side walls 21 and 22 in the embodiment of Figure 3a on the left side and the third side wall 23 connects the two first and second side walls 21 and 22 in the embodiment on the right side.
- the flat tube can be seen as such, which means that the third and fourth side walls 23, 24 are significantly shorter in their extension than the extent of the first and second side walls 21, 22.
- the tube width ie the outer extent in the lateral direction, ie B v plus the wall thicknesses of the respective third and fourth set wall 23, 24, is preferably between 9 mm and 60 mm, particularly advantageously between 10 mm and 30 mm.
- the tube width is referred to as B R.
- the tube height H is advantageously between 1, 5 mm and 30 mm.
- the wall thickness s of the outer contour is between 160 pm and 500 pm, preferably 180 pm to 250 pm.
- FIG. 3b shows the inner rib which is provided for insertion into the flat tube 20. In this case, the inner rib 30 is formed in a length By, which is longer than the inner length B v of the flat tube.
- the inner rib 30 is inserted into the flat tube 20, it is first compressed in the lateral direction according to the arrows 31, 32, so that the inner rib 30 is arranged under pretension in the flat tube 20.
- the shape of the inner rib 30 is such that at the two end portions 33, 34 an arcuate contour is provided, which merges into a meandering contour 35 with webs and bends. This causes the inner rib 30 abuts the arcuate contours of the flat tube with its arcuate contours in the region 33, 34 and the arcs 36 of the meandering structure 35 to create the first and second side walls of the flat tube inside. This creates a flat tube that has a very stable configuration after soldering.

- the sheets 36 abut on the substantially flat inner side of the first and second side surfaces 21, 22 of the flat tube 20 inside.
- FIG. 5 shows, in an enlarged detail, the end region with the third side wall 23, which is designed to be double-layered.
- the inner band edge or the inner portion of the material strip 26 is formed by a step or by an angled portion 27 such that it deviates from this level or this bend from the plane or straight line of the first side wall 21 and in the arcuate Endberetch 28th passes.
- the outer band edge or the outer portion of the material strip 29 is chamfered in the region of its band edge such that in the contact region between the first and the second band edge or in the contact region of the end of the first section with the step of the second section, a chamfering or rounding takes place, so that an adaptation of the slope is found in this area.
- the leg 73 is at the angle gamma angled whereby the leg 75 is angled away from the leg 73 again by the angle beta. This causes the legs 73 and 74 abut flat against each other and the legs 75 and 76 also lie flat against each other.
- the inner rib 79 lies flat with its end region 80 in the region of the leg 76.
- FIG. 12 shows a further exemplary embodiment for a design of a side wall of a flat tube according to the invention, wherein the side wall 100 is again formed in a double-layered manner by the legs 101 and 102, wherein the leg 101 is formed by the leg 103 and the leg 104 which are angled away from the first Side wall 105 are arranged in a double-ply parallel next to each other.
