Definitions

  • the invention relates to a spacer having two support surfaces and a jacket, wherein the jacket has at least one passage cross section for passing a fluid from a central clearance of the spacer in an outer environment of the spacer or in a reverse direction, and at least one latching cross section for receiving a sealing element wherein the sealing member comprises a sealing portion, a retaining portion, and a connecting portion connecting them and forming a constriction, the retaining portion being in an assembled state of the sealing member in the clearance and the sealing member in an assembled state of the sealing member in the vicinity.
  • the invention relates to a method for producing the radiator according to the invention and to a method for producing a radiator in which the spacer according to the invention is arranged.
  • spacers are already out of the EP-A-2 256 449 as well as the EP-A-2 256 426 known. These spacers are particularly important in so-called serial radiators, which have a plurality of heating plates are not parallel but flows through successively. This means, for example, that firstly a front heating plate and then a rear heating plate are flowed through by the heating means. For this purpose, directed flows are required at least within the front heating plate in order to achieve uniform heating there.
  • the heating plates each have two half-shells, which are profiled in such a way that parallel collecting channels and heating channels for receiving the heating medium are located between the interconnected half-shells.
  • the heating means is distributed to the heating channels in the heating plate, and then again from a second collecting channel with an adjoining riser channel via a located in the riser Schuffenan gleichö réelle by a Schuffenrohr and located in a second heating medium Schumittan gleichö réelle in a collecting channel of second heating plate is passed.
  • the Spacer arranged such that the heating means, which has first completely flowed through the first heating plate, is passed into the second heating plate.
  • the spacer prevents a "short circuit" arises and the heating means, which has already flowed through the first heating plate is not passed once again through the first heating plate or heating medium, which has not yet flowed through the first heating plate, is passed directly into the second heating plate ,
  • the spacers typically have two opposing planar support surfaces which contact opposite inner surfaces of the half shells of the respective heating plate.
  • a space of the spacer surrounding the jacket and the support surfaces corresponds to the corresponding heating medium connection opening in the heating plate and thus to the heating medium pipe or the connecting piece.
  • the known from the prior art spacers are typically formed from a formed steel pipe section, wherein in the shell of the steel pipe section is the passage cross-section through which the heating means either from the collecting channel of the first heating plate in the free space or the heating means from the free space into the collecting channel the second radiator flows.
  • the preparation of the spacers is not only quite time consuming and costly, but also error prone. This is due to the fact that the sealing elements are introduced by hand into the latching cross sections, which is very time consuming and expensive. In addition, the material selection of the sealing elements is very limited, since they must be made of an elastic rubber-like material, so that the retaining portion can be pressed by the latching cross-section. The selection of a suitable elasticity of the material of the sealing elements has proved to be restrictive.
  • the present invention is based on the object to improve a spacer and a method for its production such that a tailor-made and time-saving production of the spacers is possible and a best possible seal can be achieved by means of this spacer according to the invention.
  • the underlying object is achieved in that the latching cross-section is open or opened in such a way that when mounting the seal member whose connecting portion is inserted directly in the axial direction in the latching cross-section.
  • Another advantage of the spacer according to the invention is that it can be manufactured by machine. It is not absolutely necessary that the sealing elements must be inserted or squeezed by hand into the latching cross sections of the spacer, since the spacer according to the invention can be arranged such that the sealing elements can be automatically introduced into the latching cross sections by means of a machine.
  • At least one latching cross-section preferably two latching cross-sections, which advantageously offset by 180 ° in the spacer are arranged.
  • Between the two latching cross sections is preferably the passage cross section, through which flows in the installed state of the spacer, the fluid.
  • the spacer is made in one piece and a side surface of the connecting portion of the sealing element in its mounted state, in an unmounted state of the spacer is freely accessible. That is, a side surface of the connecting portion after the introduction of the sealing element in the spacer is not framed, that is open and visible. This is particularly desirable because a particularly quick and easy attachment of the sealing element or the connecting portion in the latching cross-section is possible without first the retaining portion must be squeezed together by the latching cross-section. The sealing element can accordingly be removed again from the latching cross-section of the spacer as required. After the spacer has been mounted in a radiator, this side surface of the connecting portion is preferably no longer freely accessible, so that the sealing element is no longer removable from the spacer, so safely remains in its sealing position during operation.
  • the spacer consists of at least two sections, wherein each at least two sections correspond to each other so that the two sections separated separating plane extends in an assembled state of the two sections through the at least one latching cross-section.
  • the at least one parting plane designates a plane or a "stepped plane” formed in particular by a plurality of parting plane parts, which runs through two sections, wherein the parting plane is of any desired design.
  • the dividing plane can be aligned in all conceivable directions in space. By "passing through the recess” is also the borderline case in which the dividing plane coincides with a border of the recess.
  • the at least one parting plane extends according to the invention between two sections by at least one latching cross section.
  • the connecting portion of the sealing element in the assembled state revolves around the two sections of the spacer is enclosed.
  • the sealing elements can be formed such that they are no longer removable from the at least one latching cross-section of the spacer after insertion into the recesses and the joining of the sections so then are positively connected to the spacer. This is particularly possible if the connecting portion of the sealing element forms a constriction and thus has a smaller cross section than the sealing portion and the retaining portion.
  • the retaining portion should preferably have a cross section which is greater than the latching cross section, so that the sealing element can not be removed from the latching cross section in the crimped state of the retaining section. Consequently, it is prevented that the sealing members can fall out of the spacer during the attachment of the spacer in the half-shells of the heating plate, thus the risk of a short circuit of the heating means between the first collecting channel and the riser channel in the first heating plate is reduced.
  • the matrices and male form in the assembled state of the spacer preferably the jacket in which the latching cross sections are located.
  • the jacket and the two support surfaces define the free space through which the heating medium is conducted from the passage cross section into the heating medium tube and into the second heating plate or the heating medium flows from the heating medium tube through the free space into the passage cross section.
  • the spacer preferably has a wall thickness of at least 1 mm, more preferably at least 2, in the region of its jacket mm, more preferably at least 3 mm. The wall thickness depends on the outer diameter of the spacer and a diameter of the inner free space.
  • the at least two sections are formed such that they form at least one passage cross-section in an assembled state.
  • the at least one latching cross section and the passage cross section can be formed by recesses in only one of the sections, wherein the recesses are closed by means of a preferably flat surface of the further sections.
  • a number of sections can be provided with corresponding recesses, which then form the latching cross section and / or the passage cross section. The at least one parting plane between two sections would thus be such that there is a recess in each section.
  • a particularly advantageous embodiment of the invention provides that the sections are two frame-shaped, preferably annular, half-shells or two C-shaped, preferably semi-circular shells.
  • the parting plane preferably extends at least over larger sections perpendicular to a central axis of the spacer.
  • the parting plane is at least partially arranged obliquely to the central axis, preferably, the angle between the central axis and the parting plane between 60 ° and 90 °, more preferably between 70 ° and 90 °.
  • the advantage of this embodiment is that the passage cross-section of the two sections can be formed and not necessarily before the joining of the sections in one of the sections was attached.
  • the frame-shaped half-shells can have both an angular and an annular contour.
  • the spacer may also consist of the two C-shaped half-shells.
  • the half-shells are semicircular or have corners.
  • the parting plane would in this case run at least partially approximately parallel to the central axis, wherein the semicircular half-shells can also be divided by two parting planes and the two parting planes preferably have an angle of 40 ° to 90 ° to each other and the respective parting plane approximately parallel to the central axis runs.
  • the invention provides that the at least two sections are connected by means of a press fit in the assembled state inextricably linked.
  • the press fit can be implemented simply and, above all, quickly by applying a pressure. As a result, the assembly process can be accelerated.
  • the interference fit prevents the sections from unintentionally releasing again after assembly, which makes them particularly well-suited for the manufacture of the spacers.
  • Unsolvable in the context of this application means that the sections are connected to each other in such a way that they can not fall apart before and during the attachment of the spacers in the radiator. Only under the influence of a desired force, the cuts may possibly separate again, but this is typically not required.
  • the at least two sections are glued together, soldered or welded. If it is not possible or desired to apply a high pressure during the assembly of the sections, ie to produce a press fit, the abovementioned variants can be used, so that the sections are permanently connected to one another. These connection variants can also be used in addition to the interference fit, thus providing additional security against the pieces falling apart.
  • a particularly advantageous embodiment of the invention provides that in each case a sealing element in the at least one latching cross section, in the assembled state of the at least two sections is inextricably linked to the spacer.
  • the sealing elements can be inserted into the recesses in the respective section, which is why solid materials can be used as sealing elements.
  • the sealing elements are formed such that they can not be removed from the spacer after assembly of the sections, so that it is not necessary to constantly pay attention during assembly, whether the sealing elements are still arranged in the spacer.
  • the sealing elements each have a constriction in the region of the recess, that is, their cross section is smaller in the region of the recess than in the regions adjacent in both directions.
  • the invention relates to a method for producing the spacer according to the invention, wherein the latching cross section is open or openable in such a way that when mounting the sealing member whose connecting portion can be inserted directly in the axial direction in the latching cross section and the spacer through Connecting at least two sections is composed and at least two sections correspond to each other, wherein at least one parting plane between two sections by at least one latching cross-section.
  • the spacer may have any shapes and does not necessarily have to be annular.
  • sealing elements are inserted into corresponding recesses of at least one section before connecting the corresponding sections and at the same time the sealing elements are connected to the spacer when connecting the sections.
  • the sealing elements are thus designed such that they can no longer fall out of the latter in the assembled state of the spacer, so the sealing elements are permanently connected to the spacer, provided that it is in the assembled state.
  • the choice of material of the sealing elements is no longer limited to elastic rubber-like material, but stiffer material can be used instead for the sealing elements.
  • a press fit in the connection of the at least two sections under application of a pressure, a press fit, is generated.
  • the generation of an interference fit can be made fast and inexpensive.
  • the press fit creates a permanent connection between the individual sections, so that the spacer can be used as a whole readily in the heating plates, or on the half-shells of the heating plates.
  • the sealing elements in the recesses do not hinder the cold extrusion and thus can be used in their recesses before joining the sections.
  • the invention also relates to a method for producing a radiator in which in particular the spacer according to claim 1 can be used, wherein it is provided that a side surface of the connecting portion of the sealing member is freely accessible in its mounted in the spacer state and the connecting portion in the region of this Side surface is covered only when the spacer is positioned between the two wall parts.
