Definitions
- Micro heat exchanger with intersecting, separate channels for the heat transfer media
- the invention relates to a micro-heat exchanger with channels arranged in alternating planes and intersecting at right angles, which carry the heat transfer media and are separate from one another.
- micro heat exchangers are described in DE-Z "Scientific Reports", FZKA 6080, pp. 53 to 60, 1 998.
- the connection of these known micro heat exchangers to other components or devices presents considerable difficulties since complicated and cost-intensive connection elements are required for this.
- micro heat exchangers of the type mentioned at the outset have a high power density, a low mass and even favorable manufacturing costs.
- the Channel arrangements in the levels are not interconnected and since they cross, heat transfer will take place in a known cross flow.
- the channels in the levels are introduced in rows next to one another in a transmitter block, in that the transmitter block ends at least on two opposite sides with a circumferential shoulder which is reduced in cross-section, and in that these Shoulders of the transmitter block are inserted flush in a correspondingly graduated receptacle of flange plates and are connected to them, or also in that the channels for a heat transfer medium are formed by flat profile sections which are arranged one above the other to form the channels for the other heat transfer medium, that the profile sections end at their ends with a reduced cross-section, circumferential section and that the shoulders are inserted flush in correspondingly graduated and spaced receptacles of flange plates and connected to them.
- the transmitter block is manufactured by machining, etching or coating processes, while in the second type, the profile sections made of extruded aluminum profiles can be cut to length and provided with the circumferential shoulders.
- the channels end flush with the device connection sides of the flange plates, the shoulders on the transmitter block or the profile sections being adapted accordingly to the graduated receptacles in the flange plates.
- An embodiment has proven to be advantageous, which is characterized in that the shoulders of the transmitter block or the profile sections in the longitudinal direction of the assigned channels have a dimension that corresponds to half the thickness of the flange plates, that the receptacles of the flange plates face the transmitter block or the profile sections have a cross-section which is adapted to the outer contour of the transmitter block or the profile sections and that the half-thickness receptacles of the flange plate merge into end sections whose cross-section corresponds to the shoulders of the transmitter block or the profile sections.
- an arrangement and shape can be selected, which is characterized in that the channels have a rectangular cross-section, the larger dimension being aligned with the assigned plane, such that the channels have a dimension of approx.
- the shape and arrangement in the profile sections can also be varied such that the channels in the profile sections have a round cross section with a diameter of approximately 0.79 mm and are arranged in the profile section at uniform intervals of approximately 1 mm and that the profile sections ' Sections have a thickness of about 1.4 mm, and that the profile sections in the flange plates are fixed at intervals of about 1 mm from one another to form individual channels for the other heat transfer medium.
- connection between the transmitter block or the profile sections with the flange plates can be improved in that the transmitter block or the profile sections with their shoulders in the receptacles of the flange plates are press-fit and / or glued, soldered or welded in.
- the micro heat exchanger is ideal for liquid or gaseous
- FIG. 1 is a perspective view of a transformer block with intersecting channels in alternating planes, which is reduced in cross section on two opposite sides with circumferential shoulders.
- FIG. 3 is a view of the transmitter connection side of a flange plate with the stepped receptacle for the transmitter block provided with a shoulder,
- FIG. 4 shows a perspective view of a micro heat exchanger with profile sections which are held spaced apart in two flange plates
- Fig. 5 is a sketch for the formation of the channels and the arrangement of the profile sections and
- FIG. 6 is a view of the transmitter connection side of a flange plate for a micro heat exchanger according to FIG. 4.
- a transmitter block 10 intersects with one another in alternating levels E1, E3 ... En or E2, E4 ... En-1
- channels 1 1 and 12 for the two heat transfer media WTM1 and WT 2.
- Channels 1 1 and 12 cross perpendicularly, but are not connected to each other. The heat exchange takes place in cross flow.
- the channels 1 1 and 12 are each introduced with a large number in equal division. If channels 1 1 and 12 are rectangular, then the larger dimension is aligned with the assigned plane.
- channels of approximately 0.4 x 0.6 mm have been selected at a distance of approximately 0.2 to 0.3 mm.
- About 1 mm was chosen for the distance between channels 1 1 and 12 in the adjacent planes, for example E1 and E3 or E2 and E4, of the same heat transfer medium WTM1 or WTM2.
- the channels 11 and 12 can be introduced using known methods, such as machining methods, etching or coating methods, in a metal block, for example made of aluminum.
- the opposite sides of the transmitter block 10 are provided with a circumferential shoulder 13, so that the transmitter block 10 ends with a section with a reduced cross section.
- the transmitter block 10 can then be accommodated 21 of the flange plate 20 are used so that the channels 1 1 are flush with the device connection side of the flange plate 20, as shown in FIG. 2.
- the receptacle 21 faces the transmitter block 10 in the center of the flange plate 20 and with the larger section in cross section.
- the receptacle 21 encloses the paragraph 13 over the entire circumference, so that a tight connection to the transmitter block 10 is achieved. This also applies to the devices or components that can be connected to the flange plates 20.
- the transmitter block 10 can be held in the receptacles 21 of the flange plates 20 by a press fit.
- the hold can be further improved by gluing, soldering or welding.
- flat profile sections 30 are arranged one above the other in spaced planes and held in correspondingly spaced receptacles 22 of the flange plates 20.
- the profile sections 30 have only the channels 1 1 for the one heat transfer medium WTM1.
- the spaces between the flat profile sections 30 form wide channels 33 for the other heat transfer medium WTM2, as shown in FIG. 4.
- the definition of the profile sections 30 with their reduced cross sections 32 at the ends is carried out in the same way by corresponding adaptation of the stepped receptacles 22 in the flange plates 30, the same flush connection being achieved.
- the channels 11 in the profile sections 30 can also have a round cross section with a diameter of approximately 0.79 mm and can be arranged in a uniform division at a distance of approximately 1 mm in the profile section 30.
- the thickness of the flat profile sections 30 is chosen to be approximately 1.4 mm and the profile sections 30 are held in the flange plates 20 in such a way that they are at a distance of approximately 1 mm, which determines the dimension of the channels 33 for the other heat transfer medium WTM2 ,
