Definitions
- the invention relates to a cross-flow heat exchanger for Condensation clothes dryer with the features of the generic term of claim 1.
- Such a heat exchanger is from DE 30 27 900 C2, Fig. 2nd and 3, known.
- housing openings form the entry and Outlet openings for the warm, moisture-laden and process air to be cooled or dried Condensation dryer.
- the process air is in the The interior of the housing is led through guide channels that pass through the Plates as well as the side walls of the receiving housing are defined are.
- the plates form flat, rectangular heat sinks the top and bottom of the plate the moisture precipitate and as condensate from the Housing outlet opening can drain.
- the plates or heat sinks are two apart overlapping, parallel and flat plate parts Aluminum sheet on only two opposite Edge parts are connected airtight. Analogous to Accordingly, receiving housings point to each other opposite, open foreheads that with corresponding openings in the side walls of the Align the receiving housing.
- Upright webs which are in the direction of flow of the cooling air extend and parallel to each other at a lateral distance assigned. These webs form together with the two Plate parts with rectangular channels in cross section.
- the webs are made of a meandering ribbed sheet formed, which alternately glued to both plate parts is.
- the meandering folded ribbed sheet gives it Connection of its contact points with the two sheet metal parts the plates the necessary rigidity for their handling for cleaning the cross-flow heat exchanger. Create also a surface enlargement to improve the Heat dissipation on the cooling air side.
- connection is made by gluing using a thermally conductive special adhesive.
- the invention is based, cross-flow heat exchanger the task in a in the preamble of claim 1 explained, to provide known training, which is in constructive aspects through special simplicity and a good heat dissipation on the cooling air side.
- a cross-flow heat exchanger allows to form the one to be cooled and channels to be dehumidified leading process channels on a To dispense with plate-receiving housing by now the moist air through channels of the air guide body forming plates is passed and the webs on the upper and lower, flat outside of the plates provided and are each located on an adjacent upper or Support the lower plate. Sheets and webs thus define together extending across the process air channels Cooling air ducts.
- the construction according to the invention is distinguished by this an extremely minimal material requirement by the Plate-forming plate parts only from one out of good thermally conductive metal or thermoplastic existing film are made to which the webs have them molded on immediately during their manufacture.
- the webs as well as the molded in the plate parts channel-like depressions for the formation of moist air ducting or condensate drainage channels lend the plate parts a cross ribbing, which despite the low Film thickness gives a high degree of rigidity.
- the plate package created in this way is then at the plate contact points the plates welded, glued or pressure together. This can either be along two opposite edge parts or, preferably, on one A large number of points of contact between the plate parts, preferably in a homogeneous distribution over the areas of the Plate parts are made. In this last way, one becomes better stability of the composite panels achieved.
- the webs can either be in the longitudinal direction or Flow direction be formed continuously, which is the formation of a laminar flow as advantageous turns out, or they can be divided lengthwise and the Web sections offset to one another transversely to the longitudinal direction be arranged, which is suitable for the formation of a turbulent Flow proves to be advantageous. In the latter case it happens Turbulence and therefore better heat exchange between the flowing medium and the air duct limiting webs and plate parts. Especially in this It turns out to be advantageous if the film is a Is plastic film and the webs by a corresponding Tooling are formed from the film without the Foil was cut at this point. The web sections then form a rounded, closed peripheral contour.
- a plate pack designed for a desired cooling capacity is sealed at the end in a frame fix.
- the dehumidification performance can thus be determined by the number of Define plates, the number of the top and bottom of the plates Bottom protruding webs should be chosen so that an optimal ratio of cooling capacity, depending on the chosen surface enlargement, to which by the number of Bridges caused pressure loss in the defined by them Can achieve cooling air channels.
- the invention makes it possible in a very simple manner powerful cross-flow heat exchanger for different Interpret services without costly interventions in their basic constructive concept to be forced.
- the invention thus offers a sophisticated, Complete construction system for cross-flow heat exchangers, which for existing device generations are compatible.
- thermoformed foils To use plastic, where to manufacture the Plate parts with preference to acrylonitrile-butadiene-styrene copolymers (ABS) or polypropylene.
- ABS acrylonitrile-butadiene-styrene copolymers
- polypropylene This has to be achieved necessary cooling capacities or the necessary Thermal conductivity and stability a film thickness between 0.15 mm and 0.50 mm, preferably 0.3 mm as advantageous proved.
- plastics are thermally insulators act, is, compared to materials with good Thermal conductivity, due to its use as a film, just accept a performance loss of 3 - 8%. However, this is compensated for by the fact that the Plastic film is thermoformable and the plate parts accordingly inexpensive and with any Have the surface enlarged.
- the film to be processed is preheated and in one tool into the desired shape in one go.
- the webs formed transversely to the channel-like depressions are made by thin metal strips inserted into the tool formed, which engage sword-like in the film.
- the metal strips Do not cut the film, but only deep-draw it.
- the webs are not continuous in the longitudinal direction but divided and preferably offset from one another transversely to the longitudinal direction are arranged, since then the flowing medium is not on Cut surfaces but the web sections a have rounded, closed leading edge.
- cross-flow heat exchanger are known, in which, analogously to the invention Construction that passes cooling air between bars which is between and across to damp or Process air channels extend.
- This damp or Process air channels are in this case folded through from Al blanks Box tubes formed while the webs to form the Cooling air ducts made of meandering folded aluminum fins are made between the levels of box pipes are introduced or glued.
- Such cross flow heat exchangers are manufactured by AKG Thermotechnik GmbH & Co. KG manufactured in 34369 Hofgeismar and distributed.
- the cross-flow heat exchanger shown has, for example five horizontal levels of humid air flowing through, in Cross section preferably approximately cylindrical Process air channels 10, which are at a radial distance from each other run parallel and preferably from level to level Gap are offset. Across the process air channels 10 and parallel to their levels extend in a total of six Levels in cross section of rectangular cooling air ducts 12.
- Both types of channels 10 and 12 are through one above the other stacked, preferably rectangular plates 14 formed, which in turn each consist of two identical shapes and plate parts 16 and 18 assigned symmetrically to one another are made (see Figs. 3 and 4).
- these plate parts 16, 18 in one piece from a film made of thermoplastic material, preferably polypropylene. You may as well in one piece from a foil made of heat-conducting metal, preferably aluminum.
- Each plate member 18 is along its two opposite longitudinal edge pieces 20 and 22 with such 20 'and 22' designated the one symmetrically assigned to them Plate part 16 preferably by gluing, welding, Pressure joining or folding tightly connected.
- each plate part 16 or 18 with molded to each other parallel, groove-like depressions 24 equipped.
- the cooling air channels 12 are on the plate parts 16, 18 transversely to the recesses 24 or their airtight interconnected longitudinal edge parts 20, 22 extending perpendicularly projecting and mutually parallel webs 26 formed.
- Each plate 14 is thus characterized by upper and lower, in webs 26 lying in a common vertical plane.
- Recesses 24 and webs 26 give the thin Plastic films of preferably only 0.20 mm to 0.40 mm Thickness a stiffness that ensures that in mutual solid bond of stacked plates 14 according to Figure 1 is a stiffened unit is achieved.
- the webs 26 of a plate 14 for forming the cooling air channels 12 engage between two webs 26 of a plate 14 located below or above them, preferably in such a way that adjacent webs 26 touch one another (1st variant ).
- the webs 26 of two plates 14, as indicated by dash-dotted lines to engage in the middle between those of the other plate 16, as a result of which the number of cooling air ducts 12 can be doubled and the efficiency of the heat exchanger increases (second variant).
- the plates 14 of the plate pack are at their ends together in a known manner each in a plastic existing holding frame 28 and 30 kept sealed what by means of an adhesive 32, preferably made of cast resin, is accomplished.
- the webs 26 of the upper and lower plates 14 are for Formation of the outside of the heat exchanger Cooling air channels 12 each through a circuit board 32 or 34 covered, the front also in the holding frame 28, 30 are set.
- the cross-flow heat exchanger thus formed thus has itself none to form the channels 10 for the condensate drain required housing on. It is a unit in one Housing opening of a condensation dryer insertable, for its handling on its front A handle 38 is provided on the end face.
- a method of manufacturing the plate parts 18 Metal foil is illustrated in Figures 5 and 6.
