Definitions

  • the invention relates to a cooling and holding body for heating elements, in particular PTC heating elements or flat heaters, a heater with such a cooling and holding body and a method for producing such a cooling and holding body.
  • Such heaters 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 assembly is provided in the recess, which are moved by means of a set screw can 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.
  • An improvement of this known device is in the DE 2006 018 151 A1 disclosed to the assignee.
  • 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.
  • DE 40 10 620 A1 . DE 28 04 818 A1 . DE 201 20 821 U1 and EP 2 053 902 A1 disclose further cooling and holding bodies for heating elements according to the prior art.
  • 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. According to the invention this object is achieved by the holding and cooling body according to claim 1, the heater according to claim 15 and the method according to claim 16.
  • the invention is based on the idea to provide a cooling and holding body for heating elements, in particular electrical heating elements, in particular PTC heating elements or flat heaters, which has a flat housing with at least one heating shaft in which at least one heating element is arranged.
  • the heating shaft has opposite shaft walls, between which the heating element is clamped.
  • the heating shaft has at least one side slot which separates the shaft walls such that the distance between the shaft walls for mounting the heating element is variable.
  • On the flat housing engages at least one over the flat housing to the outside projecting clamping section.
  • the clamping portion spans the side slot and is elastically deformed in the mounted state of the heating element for generating a force acting on the heating element pressing force of the shaft walls.
  • the heating elements is provided according to the invention that the at least one clamping section is elastically deformed. This means that the deformation takes place in the area of the Hooke's straight line and is proportional to the stress that is generated in the tensioning section.
  • the deformation below the elastic limit optimizes the clamping force with which the heating elements are clamped in the heating shaft. 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 high clamping force a constant maximum heat transfer from the heating elements is achieved on the material of the holding and cooling body.
  • the elastic deformation causes the force with which the heating elements are pressed to act as a spring force according to the respective material constant. A readjustment of the pressure or clamping force is not required.
  • the heating shaft has at least one side slot which separates the shaft walls in such a way that the distance between the shaft walls for mounting the heating element can be changed. This will cause the distance between the shaft walls to be increased to introduce the heating element (s) into the heater shaft. In the assembled state of the heating elements or the distance between the shaft walls is reduced, so that these rest on the heating element for heat transfer and fix the heating element in the heating shaft.
  • the contact force is due to the outside generated on the flat housing projecting clamping portions or a single outwardly beyond the flat housing protruding clamping portion which engages the flat housing and spans the side slot.
  • the one or more clamping portions are elastically deformed and act as springs or similar to leaf springs, which produce in the region of the shaft walls acting on the heating elements contact forces. The contact forces act in opposite directions inwards.
  • the excess between the heating element and the heating shaft is set so that the clamping sections or the clamping section elastically deform due to the slightly spaced apart side slot or the slightly spaced apart side slots.
  • the heating elements are thus arranged between the shaft walls in the mounted state in a press fit.
  • the expert makes a setting of a suitable oversize as a function of the respective material properties of the flat housing in such a way that adjusts the elastic deformation of the clamping sections in the assembled state.
  • clamping sections can be used for easy installation of the heating elements. By acting on the clamping sections with a relative to the flat housing inwardly acting mounting force increase the clamping sections their radius and open the side slot, which thus acts as a mounting slot.
  • the housing parts connected to the clamping sections are deflected outwards. This results in a slight increase in the distance between the shaft walls, which is sufficient to bring or insert the heating element or elements with an insulating film in the heating shaft.
  • the mounting force is released and the clamping sections try to return to their stress-free state. Since the clamping sections are thereby blocked by the heating elements or the heating element, they produce at the shaft walls the desired holding or pressing force in an elastic range dependent on the respective material constant.
  • the deformation of the clamping sections for mounting takes place in the area of Hooke's Straight lines, ie below the elastic limit.
  • the mechanical expansion can be supplemented or replaced by a thermal expansion (shrinking).
  • the over the flat housing projecting outward clamping portion may be formed as a convexly curved clamping portion.
  • the convex curvature of the clamping section means that it bulges outwardly with respect to the outer walls of the flat housing or protrudes outward curved over the straight walls of the flat housing.
  • the over the flat housing projecting outward clamping portion straight legs, in particular two straight legs, which are interconnected at an angle.
  • the legs together with the outer wall of the flat housing form a triangular cross-sectional profile.
  • the distance between the apex of the curved clamping section or between the tip of the triangular clamping section, that is generally the maximum distance between clamping section and flat housing, is dimensioned so that a sufficient spring travel is available for the assembly.
  • At least one shaft wall and an outer wall of the flat housing extending parallel to the shaft wall are connected by at least one transverse web.
  • the transverse webs act as cooling ribs, which increase the heat transfer of the surface of the cooling and holding body.
  • the length of the clamping portion is increased transversely to the longitudinal extent of the side slit.
  • the angle between the clamping portion and flat housing in the region of the point of attack is an acute angle and adjusted so that a force acting perpendicular to the side slot mounting force or acting in the opposite direction pressing force can be generated.
  • the attack points can attack on the outer edges of the flat housing. This results in the maximum distance of the attack points from the side slot. It is also possible that the points of attack of the chuck portion farther in, ie closer to the side slit, i. are arranged between the outer edge of the flat housing and the side slot. This embodiment has the further advantage that a relatively large radius of the convexly curved clamping portion and thus a small distance of the clamping portion of the housing side can be adjusted.
  • the cooling and holding body can be made compact. The widening of the heating shaft is generally determined by the radius of the tensioning section or the chord radius, the spacing of the chordal connections or the points of application, the material thickness, the material and also the shape of the tensioning section (for example triangular or curved).
  • the mechanical properties are determined by means of angle attack, fixed bearing and contact pressure.
  • the side slot and the points of attack of the clamping portion are each provided perpendicular to the heating shaft side walls of the flat housing, which are connected to the clamping portion at the points of attack.
  • the transition from the side walls to the clamping portion has on the inside in each case a rounding or a radius.
  • the notch effect and thus the plastic deformation is reduced or completely prevented by the rounding in the region of the transition from the side walls to the clamping section.
  • the cooling and holding body can be made particularly compact and simple, for example by pultrusion be made.
  • At least two parallel heating ducts can be provided, which are separated by a core arranged between the heating ducts.
  • Each heating shaft has at least one side slot.
  • This embodiment allows the stacked arrangement of a plurality of heating elements in different planes, wherein the ease of assembly and the constant contact pressure due to the elastic deformation of the clamping portions and the clamping portion are maintained.
  • a substantially square shape for mounting a fan with corresponding screw or clip fasteners is possible. Due to the length of the flat housing, the power output can be influenced.
  • the respective inner shaft walls may be formed by outer walls of the core, wherein the outer walls are in turn connected to each other by transverse webs.
  • the core thus forms a common boundary of the two Walkermchte by the outer walls of the core form the respective inner shaft walls.
  • the outer shaft walls of the two Walkermchte are formed by the flat housing and arranged in each case closer to the outer surface of the flat housing.
  • the connection of the outer walls of the core by transverse webs increases on the one hand the stability of the cooling and holding body, in particular of the core, and on the other hand, the area effective for the heat transfer surface.
  • the transverse webs thus act as cooling ribs.
  • each side slot is associated with a single clamping section.
  • a single clamping section may be associated with a plurality of side sections located on one and the same side of the flat housing. The assignment of a single clamping section to several side sections results in a simple construction of the cooling and holding body. If each side section is assigned a single clamping section, the installation of the heating elements in the individual heating ducts is simplified.
  • the thickness of the clamping sections or the chords between the points of attack, ie transversely to the longitudinal extension of the flat housing changes.
  • increased buckling loads are possible.
  • the clamping sections are thicker in the middle and become thinner towards the ends of the legs, ie towards the points of attack.
  • the core is fixedly connected to the flat housing, in particular fixedly connected by the clamping sections.
  • This embodiment is particularly suitable for the embodiment in which each side slot has its own clamping section.
  • the clamping sections have the dual function, on the one hand apply the contact pressure, on the other hand to fix the core in a certain position, in particular centrally in the cooling and holding body. Other arrangements of the core in the cooling and holding body are possible.
  • the core can be arranged freely in the flat housing. This means that the core is not directly, i. materially connected to the flat housing. This embodiment is particularly suitable in combination with the single clamping portion associated with a plurality of side slots on one and the same side of the flat housing.
  • a first longitudinal edge of at least one shaft wall is connected to the flat housing.
  • a second longitudinal edge of the shaft wall is arranged opposite the first longitudinal edge, wherein the second longitudinal edge is freely movable such that the location of the shaft wall can be changed.
  • the shaft wall is coupled to the flat housing at a first longitudinal edge.
  • the second longitudinal edge which lies opposite the first longitudinal edge is free and can be moved relative to the flat housing in such a way that the spatial position of the shaft wall can be changed.
  • the movement of the shaft wall is initiated by a deformation of the flat housing over the first longitudinal edge.
  • a further increase in power can be achieved if, in the embodiment described above, the shaft wall is connected to a stiffening rib which acts on the shaft wall between the two longitudinal edges and is connected to the flat housing in the region of the first longitudinal edge. The movement is thereby introduced not only in the region of the first longitudinal edge in the shaft wall, but also by the stiffening rib. Thus, the contact pressure on the heating element is improved and thus increases the power output.
