Definitions

  • the invention relates to a cooling and holding body for heating elements, in particular PTC heating elements, a heater with such a cooling and holding body and a method for producing such a cooling and holding body.
  • a cooling and holding body for heating elements with the features of the preamble of claim 1 is made DE 10 2006 018 151 A1 and DE 38 16 819 A1 known.
  • Such cardiac devices are usually equipped with electrical heating elements.
  • the holder of these heating elements should on the one hand allow a good heat transfer and on the other hand a constant secure fixation.
  • the frequent and depending on the operating conditions temperature changes can lead to fatigue due to aging and thus to a reduction in the holding force with which the heating elements are fixed. As a result, the heat transfer is deteriorated. If the hold function is completely eliminated, it can even lead to a total failure of the device.
  • FIG DE 196 04 218 A1 An example of a known heater with a PTC element is shown in FIG DE 196 04 218 A1 described, in which the PTC element is mounted in a centrally arranged rectangular recess.
  • a Double wedge arrangement provided in the recess, which can be moved by means of a screw to change the width of the double wedge assembly.
  • the PTC element can be jammed in the recess.
  • the double wedge assembly is expensive and does not solve the problem of reducing the clamping force due to material fatigue. To avoid this, the double wedge assembly would have to be adjusted by operating the screw.
  • the heating element is arranged in the centrally arranged recess of a heat exchanger, wherein the contact inner surfaces of the recess lie flat against the heating element.
  • the holding force is achieved in that after installation of the heating element sidewalls of the heat exchanger are bent inwardly, whereby the distance between the contact surfaces of the recess is reduced.
  • the arranged between the contact surfaces heating element is thereby clamped flat.
  • This attachment is a stable holder that provides a constant high holding force and thus a constant good heat transfer from the heating element to the heat exchanger without readjustment.
  • the buckling of the side walls leads to a plastic deformation of the wall material, which is not optimal due to the frequent temperature changes for the holding conditions.
  • the invention is therefore based on the object to improve a cooling and holding body of the type mentioned in such a way that a secure mounting of the heating element or the heating elements in the cooling and holding body is achieved despite frequent temperature changes.
  • the invention is further based on the object to provide a heater with such a cooling and holding body and a method for producing such a cooling and holding body.

  • the sides of the polygonal profile are elastically deformed. This means that the deformation takes place in the area of the Hook's straight line and is proportional to the stress that is generated in the polygon profile.
  • the deformation below the elastic limit optimizes the clamping force with which the heating elements are clamped in the receiving areas of the heating element receptacle. Settlements resulting from material aging are avoided in contrast to plastic deformation.
  • the clamping force with which the heating elements are fixed remains constant or at least substantially constant despite the temperature changes. Due to the constant clamping force, a substantially constant heat transfer from the heating elements to the material of the holding and cooling body is achieved.
  • the elastic deformation also causes the force with which the heating elements are pressed acts as a spring force. A readjustment of the pressure or clamping force is not required.
  • the formation of at least the outer part as a polygonal profile has the advantage that the heating power is increased and a clamping of the heating elements without additional clamping elements is possible.
  • the omission of the clamping elements enables a compact design of the holding and cooling body.
  • not a single centrally arranged receiving area is provided, but a plurality of receiving areas distributed in the circumferential direction of the outer part.
  • the heat output in the holding and cooling body is better distributed and allows efficient heat dissipation.
  • the formation of the outer part has a polygonal profile the further advantage that this can be easily produced, for example by extrusion.
  • the corners of the polygonal profile forming clamping surfaces which are adapted to the shape of the heating elements, in particular flattened, whereby a particularly good heat transfer is achieved.
  • the flattened rake surfaces are particularly well suited for use with flat heating elements in the form of PTC resistors directly connected to the outer and inner parts, further improving heat transfer.
  • Other clamping fixtures, in particular profiled fixtures are possible.
  • the wall thickness of the outer part may be greater in the region of the corners of the polygonal profile than in the region of the sides of the polygonal profile. As a result, a uniform heat dissipation in the region of the corners or clamping surfaces is achieved.
  • the sides of the polygonal profile are concave, convex or straight. This results in various ways of mounting the heating elements, in particular different ways of initiating the assembly force.

  • the shape of the holding surfaces 17 and the clamping surfaces 16 is adapted to the outer contour of the approximately cylindrical PTC cartridges 10 b, as well as in Fig. 7 shown.
  • the holding surfaces 17 and the clamping surfaces 16 are formed as half shells.
  • the half-shells are profiled and engage in a corresponding counter-profile of the PTC cartridges, much like a tongue and groove system.
  • Fig. 10 the cooling and holding body is shown in the installed state, wherein the axial end 24 of the cooling and holding body with a fan 25th connected is.
  • the cooling and holding body is located in a housing 27, which may be insulated, for example when the current-conducting PTC resistors are connected directly to the outer part 13 and the inner part 14, as in the embodiment according to Fig. 1 shown.
  • the end face of the housing 27 may be closed by a protective grid, not shown.
  • FIG. 11 A modification of the outer part 13 is in FIG. 11 shown, in which the wall thickness or the thickness of the polygon sides 19b changes in the circumferential direction of the outer part 13. Specifically, the wall thickness decreases towards the edge regions of the polygon sides 19b, ie towards the corners 19a.
  • the polygon sides 19b taper toward the corners 19a.
  • the maximum wall thickness is in the middle region, specifically in the region of the apex of the polygon side 19b.
  • the vertex is indicated by the dashed line S, which intersects the center of the outer part 13 and bisects the polygon side 19b.
  • the change in the wall thickness is continuous.
  • the radius of the polygon side 19b between the vertex and the corner 19a is denoted by R.
  • stiffening of the polygon side 19b is achieved, which improves the transmission of force into the edge regions.
  • Other stiffeners of the polygon side 19b are possible, for example stiffening ribs which prevent local deformation of the polygon side 19b in the region of the vertex or at the point of application of the mounting force or reduce.
  • the increase in the wall thickness in the region of the apex of the polygon side 19b extends along the entire axial length of the outer part region.
  • the increased flexibility of the inner part 14 according to the Figures 12 . 13 is achieved in that the retaining surfaces 17 are supported radially inwardly only by the sides 19 b 'of the polygonal profile.
  • the differences from the embodiment according to FIG. 1 no webs provided which support the retaining surfaces 17 radially inwardly and thus stiffen the inner part 14.
  • the inner part 14 according to the Figures 12 . 13 is designed without installation, ie, no support elements for the retaining surfaces 17 are provided in the interior of the inner part 14. The retaining surfaces 17 can thus move radially inward or radially outward depending on the material properties and the mounting force to be applied.
  • the inner part 14 according to FIG. 12 . 13 is designed as a polygonal profile, wherein the examples according to Figures 12 . 13 differ by the shape of the polygon sides 19b '.
  • the polygon sides 19b ' concave, that is curved inwardly.
  • the holding surfaces 17 are pulled radially inwardly and the inner part 14 is reduced in size.
  • the polygon sides 19b ' are convex.
  • the polygon sides 19b ' curve outward. If in the inner part 14 according to FIG. 13 an expanding force or a mounting force is applied, which acts on the polygon sides 19b 'from the inside to the outside, the flat sides or the holding surfaces 17 are also drawn radially inwardly, whereby the mounting gap increases.
  • the outer part 13 forms a mechanical tensioning element in the form of a polygonal profile, wherein the contact pressure force is achieved by elastic deformation of the outer part 13.
  • the deformation is thus effected in the stress-strain diagram in the region of Hooke's straight line.
  • the clamping effect is reinforced by the geometry of the outer part 13, which has between the clamping surfaces 13 clamping portions 18, in particular convex or concave curved or straight clamping portions 18.
  • the clamping sections 18 bridge the distance between the clamping surfaces 16 and connect them.
  • the same principle can be realized by the inner part, which is also designed as a polygonal profile.
