Embodiment Construction

[0027] according to figure 1 , the stacked plate heat exchanger 1 comprises a plurality of stacked plates 2 stacked on top of each other and welded to each other, here are first stacked plates 4 between which are alternately formed Hollow spaces in different media3. At least one first passage opening 5 and at least one second passage opening 6 are provided in the first stack plate 4, wherein a dome 7 protruding from the stack plate plane surrounds the at least one first passage opening (see also Figure 2 to Figure 11 ). The stacked plate heat exchanger 1 additionally comprises an immersion tube 8 formed as a separate part which has to be tightly assembled in the stacked plate heat exchanger 1 and creates a predetermined flow path through the stacked heat exchanger 1 . This dip tube 8 formed as a separate part involves relatively high costs and also has a relatively high assembly outlay, so the stacked plate heat exchanger 1 according to the invention (eg Figure 2 to Figur...

Abstract

The invention relates to a stacked plate heat exchanger (1) comprising a plurality of stacked plates (2, 4), which plurality of stacked plates (2, 4) are stacked on top of each other and welded to each other, wherein at least one first passage opening (5) and at least one second passage opening (6) are provided in a first stacked plate (4), wherein a dome (7) protruding from the plane of the stacked plates surrounds the at least one first passage opening (5). Important to the present invention are: -at least one second stacked plate (11) is provided, which likewise has at least one first passage opening (5) and a second passage opening (6) of the protruding dome (7), wherein an annular flange (12) protruding from the stacked plate plane surrounds said second passage opening (6); the firststacked plate (4) and the second stacked plate (11) form an immersion tube channel (17).

Description

technical field [0001] The invention relates to a stacked plate heat exchanger according to the preamble of claim 1, comprising a plurality of stacked plates stacked on top of each other and welded to each other, between which stacked plates for two media are alternately formed hollow space. Background technique [0002] Stacked plate heat exchangers are known from the prior art, which are used, for example, as oil coolers, iConds or cooling devices in motor vehicles. A stacked plate heat exchanger comprises a plurality of longitudinally stacked plates stacked on top of each other with hollow spaces formed therebetween. The two media (cooling medium and medium to be cooled) flow in hollow spaces arranged one above the other so that heat exchange can take place between the two media. Here, the hollow space is delimited by the surface and the surface edge of the respective stack plate and the adjacently supported stack plate. In each stacking plate, generally four openings ...
