Definitions
- the invention relates to a heat exchanger according to the preamble of claim 1.
- Heat exchangers with plate-shaped or disk-shaped flow channels are known in many designs, for. B. as a disk oil cooler, disk evaporator or so-called stacked disk heat exchanger. They consist of a plurality of identical sheet metal parts, which are arranged or stacked one above the other, form flow channels and are connected to one another by soldering. The flow channels arranged one above the other are in flow connection via transverse connecting channels, which act as collection and distribution channels. It is known to form the connecting channels as cup-shaped characteristics, and to be soldered together in the region of a flat annular surface, wherein the cups are formed from the plates or slices of the flow channels. These known connection channels have the disadvantage that the flow resistance is relatively high, since the flow cross-section is narrowed by the Napfine. This increases the pressure drop of the heat exchanger.
- the connecting channel is formed by plug-in, self-centering pipe socket.
- the end regions of the pipe sockets which are preferably producible as passages, are conical, either conically widened or conically tapered, each with the same angle, so that they can be plugged into one another and abut one another. Due to the conical end areas, a centering takes place when inserting each other. At the same time results in a contact surface, which can be soldered, so that there is a fluid-tight connection channel between adjacent flow channels. Due to the shape of the invention, there is the advantage of a low flow resistance for the connecting channel, since it is formed almost smooth-walled and has no interference edge.
- the connecting channels according to the invention with conical end regions can preferably be used in disk heat exchangers known per se, wherein the pipe sockets, by nesting, form a distributor channel and a collecting channel, which each have the advantage of a low flow resistance.
- the flow channels as ring channels preferably with a square outline, ie be formed according to the earlier patent application of the applicant with the official file number 10 2005 004 777.7.
- Embodiments of the invention are illustrated in the drawings and will be explained in more detail below. Show it
- Fig. 1a - 1d a heat exchanger with connection channel after the
- FIG. 2 shows a pipe socket according to the invention with conical extension
- FIG. 3 shows a pipe socket according to the invention with conical taper
- FIG. 4 shows a connecting channel with nested tube stubs
- Fig. 6c two slices after joining and soldering.
- 1a to 1d show a heat exchanger with flow channels and a connection channel according to the prior art.
- FIG. 1a shows a lower plate 1 of a flow channel with an upwardly shaped approximately cylindrical cup 1a, which has a flat, annular soldering surface 1b.
- Fig. 1b shows a lower plate 2 of a flow channel with a downwardly shaped approximately cylindrical cup 2a, which has an annular solder surface 2 b.
- FIG. 1c shows the connection of the two disks 1, 2, the annular surfaces 1b, 2b lying on one another.
- Fig. 1d shows a section through a connecting channel 3, which through the two superimposed and soldered together cup-shaped
- Variants 1a, 1b, 2a, 2b arises. In the area of the soldered annular surfaces there is a reduction in diameter, namely of one ximal diameter D to a minimum diameter d.
- This known design of the connecting channel 3 leads to an increased flow velocity and to an increased pressure loss for the heat exchanger.
- Fig. 2 shows an inventive design of a pipe socket 4, which is formed from a disc 5 which defines a flow channel.
- the pipe socket 4 consists of a circular cylindrical portion 4a and a conically widened portion 4b. The production takes place initially as a cylindrical passage with subsequent conical widening of the section 4b.
- Fig. 3 shows a pipe socket 6, which is formed from a disc 7 and has a circular cylindrical portion 6a and a conically tapered portion 6b.
- Fig. 4 shows the two pipe sockets 4, 6 after joining and soldering, wherein the same reference numerals are used for the same parts.
- the conically tapered region 6b is inserted into the conically widened region 4b and forms an annular conical contact surface for the soldering of the two connecting pieces 4, 6. Due to the small conicity of the two end regions 4b, 6b, only a slight change in the inner diameter results.
- the nested pipe stubs 4, 6 form a connecting channel 8, which has a maximum diameter D1 and an approximately same minimum diameter D2 without interfering edge and thus a relatively low flow resistance.
- 5a and 5b show two corner cut-outs of two panes 9, 10, each having a conically widened pipe socket 4 and a conically tapered pipe socket 6.
- the discs are parts of annular flow channels, not shown here.
- FIG. 6 a shows a disk 11 designed as a square annular channel, which has a conically widened pipe socket 4 and a conically tapered pipe socket 6, which each lie diagonally opposite one another.
- cup-shaped closed passages 12, 13 are arranged, which are also formed from the disc 11 and serve as spacers or for support.
- Fig. 6b shows two superimposed before joining discs 11, 14, which are identical, but rotated by 180 ° (by a diagonal).
- conically widened and conically narrowed pipe sockets 4, 6 can be joined on each diagonally opposite corners and closed passages 12, 13 and 15, 16 can come into contact as spacers.
- FIG. 6c shows the two panes 11, 14 as cut-outs and partially cut away, with the closed passages 12, 15 resting on one another with their plane surfaces and being soldered there - here, therefore, only one support and no flow passage takes place.
- connecting channels 17, 18 are formed, which connect the upper disc 14 and the lower plate 11, which are each part of an annular flow channel.
- the flow cross-section of the connecting channels or the nested pipe sockets can be elliptical or oval or have other shapes.
- the pipe socket connector according to the invention can be applied to all types of plate and disc heat exchangers.
