Definitions
- the invention relates to a method for Manufacture of a heat exchanger for a condensing boiler, first preparing a mold and with cores for the formation of water and fuel gas Surfaces in the heat exchanger and then the Casted mold and then the cast Removed heat exchanger and post-processing is subjected.
- the invention also relates to a core to be used in the method for training the water-side surfaces.
- Condensing boilers are mostly castings Aluminum alloys. Condensing boilers are included different services manufactured and offered. ever the higher the output of the condensing boiler, the greater its heat exchanger surface must be in order to meet the requirements to be able to fulfill.
- a manufacturer's offer for heat generators includes often not just different types of boilers, but also the division of each boiler type into different ones Performance classes, the smallest, for example for condensing boilers intended for use in households Example can have a power of 10 KW to 15 KW. Larger boilers have correspondingly higher outputs, structurally or constructively any Performance can be achieved. Limits become only by possible at the respective location Dimensions set. This leads to the fact that the Manufacturer a wide range with one Manufacture a variety of different heat generators and must be ready.
- the invention has for its object a method to find a heat exchanger where the Disadvantages described above no longer occur.
- Claim 1 This object is achieved by the features of Claim 1 solved. It becomes one at a time predetermined number of identical cores for the Formation of water-side surfaces alternately with similarly designed cores for training areas on the fuel gas side by side and as a sum is cast in a mold in the monoblock.
- the procedure is such that the number of cores lined up depending on the desired output of the heat exchanger to be manufactured is chosen.
- Each core can be designed to be a Basic unit that trains when in a shape is used to form a heat exchanger after the pouring leads, for example, a Has power of 10 KW or 15 KW.
- a Has power 10 KW or 15 KW.
- cores that are also in are designed in an inventive manner. Every core that is available as a so-called basic unit in that he has a roughly one plate, preferably a rectangular plate, the same Basic shape has that in a corner area at one end one of the two longitudinal edges of the plate is a first Shaping to form a water space provided which is a heating flow of the to be manufactured Heat exchanger corresponds and that in a corner area on opposite end of the same longitudinal edge of the plate a second shape to form a one Heating return provided corresponding water space is.
- one of several identical cores assembled core package in a mold for casting a heat exchanger used.
- the arrangement several core basic shapes such that the shapes at cores assembled into a core package one transverse to the ones that form the basic shapes of the nuclei Escaping plates lie both in the individual cores as well as in the same cores which is composed of a core package.
- the cores are designed so that those of them trained cavities for water management a forced route pretend to an approximately meandering flow leads from the bottom up. Below is that Heating return appropriate water space available, above a shape to form a water space that the Heating return corresponds.
- the advantages for the Formation of core to be used on the water side for who also claims independent protection achieved in that the formation of a Heating flow corresponding water space provided first design is combined with a design that the formation of a water space that serves one aligned parallel to the heating flow, however separate collector channel corresponds.
- the core according to the invention consequently becomes a Heat exchanger designed in which the Heating return flow of water, which is in the Flow through the heat exchanger has heated, first in crosses a collector channel.
- the collector channel is open and opens into a water space that corresponds to the one described above Heating flow corresponds.
- the core its first page, which of the second page opposed to the training of means Post-processing of connections to be opened for Heating flow and heating return is involved
- the centerpiece is applicable, which is the design of a the outlet of the collector channel seated deflector serves that exits from the end of the collector channel Water in and through the heating flow to opposite second side of each cast Can return heat exchanger. On this side, or lateral outer surface to which it is returned, is in a finished heat exchanger Connection for the heating flow, so that in the heat exchanger Drain heated heating water into a heating circuit can.
- This configuration of the core with a core which the training of a deflector serves both at a single core for casting a heat exchanger is used with relatively low power, as well as a core package that is cast as a monoblock becomes.
- the cores can be prefabricated so that they can be used for Formation of core packages can be provided. It can be easily done in no time Heat exchangers with different performances in relative manufacture large quantities, including one Production changeover to larger or smaller ones Heat exchanger does not require significant set-up times because always the same cores are used.
- the cores consist in the usual way with binder mixed sand, with the binders preferred are curable.
- the temperature of the potted Molten metal evaporates the binder, so that every cast heat exchanger by simple and Coring the usual shaking of the molding sand.
- a heat exchanger for one Manufacture of condensing boilers first becomes a mold prepared and equipped with a core 1, as in Fig. 1 is shown, and for the formation of the surfaces on the water side in the heat exchanger.
- the core 1 will of course not continue with here shown cores combined, that of training surfaces on the combustion gas side.
- the core 1 shown here in Fig. 1 on both sides Cores for fuel gas spaces are enclosed, that is between two cores for fuel gas rooms can be arranged.
- the core 1 has an approximately rectangular plate 2 same basic shape.
- a first shape 5 to form a Water space provided, which a heating flow of the corresponds to the heat exchanger to be manufactured.
- the Heating flow is designated here with the reference number 6.
- a second shape 7 to form a heating return 8 appropriate water space provided.
- the first shaping 5 provided is of a design 9 combined, which serves to form a water space, the one aligned parallel to the heating flow 6, however, this corresponds to separate collector channel 10.
- a core piece is designated, which the Design one in the finished heat exchanger before Collector channel 10 seated deflector is used, which from the visible end of the collector channel 10 emerging here Water in and through the heating flow 6 opposite side 14 (Fig. 4) of each cast heat exchanger is able to return, the opposite side of the second heat exchanger Page 14 corresponds to the form drawn in FIG. 4.
- FIG. 2 shows two cores according to FIG. 1 seen in the direction of arrow II in Fig. 1.
- the two Cores 1 and 1 'can be put together as a package is shown in Fig. 3.
- the same components are included same reference numbers, possibly with index, designated by the arrows 12 and 13 in Fig. 2 given in a finished heat exchanger
- Direction of flow of a heating return (reference number 12) and a heating flow (reference number 13) indicated is.
- Fig. 4 the mold or the outer contour is one Heat exchanger again schematically in one view shown.
- the connection options of Heating return and heating flow are through the corresponding direction arrows of a lead or Return flow 12 and 13 indicated.
- Fig. 5 shows a view of a total of four cores to form surfaces on the water side Core package.
- the same components are the same Designated reference numbers.
- Fig. 5 illustrates the particularly advantageous training a flat back of a heat exchanger where the Connections for heating flow and heating return on same side 14 (see Fig. 4) are formed.
- the cores that complement the core package here Formation of surfaces of the fuel gas to be produced Heat exchangers are not shown.
- Corresponding cores can, for example, the spaces between the here Fill in visible panels and thus into the formed ones Packages be integrated.
