Definitions

  • the invention relates to a carrier plate for a circuit board equipped with electronic components of a household appliance, which has receptacles for the circuit carrier. Moreover, the invention also relates to an arrangement with a carrier plate and an electronic component carrier, as well as an induction hob with a corresponding arrangement.
  • Household appliances in particular induction hobs, a variety of electronic components are present, which must be cooled during operation.
  • This relates in particular to the power electronics components which are provided for supplying energy to the inductors of the induction hob.
  • the corresponding is from the WO 2004/060020 A1 known.
  • a carrier plate according to the invention is designed for carrying or picking up a circuit carrier of a domestic appliance equipped with electronic components.
  • the carrier plate is designed for receiving the circuit carrier, and has corresponding representational recordings for this purpose.
  • On the support plate a wall comprehensive elongated flow channel is formed, which is designed to conduct cooling air from electronic components of the circuit substrate.
  • the walls bounding the flow channel are at least partially formed by the carrier plate itself. The walls are arranged so that the channel shape of the flow channel is formed and thus forms an elongated and at least partially closed hollow body.
  • a specific component namely the flow channel
  • the flow guidance of the cooling air can be substantially more targeted and efficient, and the cooling of the electronic components can thus take place substantially more efficiently.
  • this integral flow channel it is also avoided by this integral flow channel that cooling air is blown out virtually uncontrolled and thus blown into unwanted zones.
  • the flow channel is also partly formed by the carrier plate itself, a very component-minimized as well as mechanically stable and robust configuration can be achieved.
  • the flow channel is designed to be open on one longitudinal side and a receiving shaft for lateral insertion of an electronic component carrier is formed.
  • the electronic component carrier can at least partially also extend into the receiving shaft and thus the cooling effect when passing the cooling air is particularly high.
  • a quasi Hineineruxn the electronic component carrier in the flow channel in turn a very space-minimized design provided. Not least can be achieved by such an arrangement, a very mechanically stable positioning of the electronic component carrier, since the electronic component carrier can be at least partially held and positioned by the part formed by the support plate of the flow channel.
  • the receiving shaft viewed in the longitudinal direction of the flow channel, is delimited on an open side wall and / or on an open top wall by a flow channel inlet flange and a flow channel outlet flange.
  • this receiving shaft is clearly delimited front and rear, and thus the insertion of the electronic component carrier can also be carried out in a very targeted and quasi-guided manner. This is particularly advantageous in particular when the electronic component carrier has dimensions which allow an exact insertion into the receiving shaft.
  • the introduction can be carried out particularly simply and reliably without being accompanied by any spreading or jamming of the electronic component carrier.
  • an open side wall of the flow channel has a reduced in height, in particular a maximum of one third of the height of the flow channel supported wall web, which is preferably provided functionally for positioning of the component carrier.
  • this wall web extends over the entire length of the receiving shaft. It therefore also extends in particular from the flow channel inlet flange to the flow channel outlet flange.
  • the electronic component carrier has a compatible recess into which the wall web can then engage.
  • the wall web is at least partially non-rectilinear design.
  • the adaptation to the electronic component carrier can be done individually.
  • the wall web extends at its two opposite ends with a small or short section angled in the direction of the outer wall portions of the Strömungskanaleinlassflansches and the Strömungskanalauslassflansches.
  • the wall web is therefore in particular slightly outward with respect to the outside of the flow channel inlet flange and the flow channel outlet flange offset wall area. This is particularly advantageous for receiving and introducing the electronic component carrier in the receiving shaft. In addition, this ensures that especially in a non-rectilinear wall web, which then preferably does not hineinerstreckt into the flow channel with its non-linear sections, no undesirable turbulence of the cooling air flow are effected.
  • the flow channel is delimited on the front side by a flow channel inlet flange of wall regions.
  • This is in particular funnel-shaped. This specific shape allows a particularly large intake of the cooling air blower in a cooling air flow.
  • a flow opening for introducing the cooling air into the flow channel is formed in the bottom of the carrier plate adjacent to the flow channel inlet flange.
  • this flow opening is not arranged overlapping the surface of the flow channel inlet flange.
  • the flow channel is bounded on the rear side by a flow channel outlet flange of wall regions, which is formed with its ceiling wall sloping downwards. This is particularly advantageous with regard to the cooling air flow to the outlet. In this way, it is possible to divert the warmed up cooling air flow to be discharged.
  • a flow opening for discharging the cooling air from the flow channel is formed in the bottom of the support plate.
  • this further flow opening is quasi covered from above by the flow channel hood-like, in particular covered by the Strömungskanalauslassflansch.
  • the very targeted discharge through the bottom of the support plate can be achieved and an undesirable influx of other components on the top of the support plate, on which the flow channel is formed, can be avoided.
  • the carrier plate is integrally formed.
  • a very component-minimized realization can be realized.
  • this can be a Implementation be realized from plastic, which can then be made in particular as a plastic injection molded part.
  • the flow channel is arranged to extend horizontally when viewed from above on the carrier plate. Additionally or instead, it can also be provided that the flow channel is arranged in a rear view of the carrier plate in a rear third of the surface dimensions of the carrier plate. This is particularly advantageous with regard to the arrangement of further components, on the one hand on the support plate itself, on the other hand on the circuit carrier and also adjacent to the support plate itself. Especially with regard to the positioning of the blower in a household appliance can be a particularly by this arrangement of the flow channel advantageous arrangement can be realized with respect to the installation space compactness.
  • the invention relates to an arrangement with a carrier plate according to the invention or an advantageous embodiment thereof.
  • the arrangement further comprises an electronic component carrier on which at least one electronic component to be cooled is arranged.
  • the electronic component carrier is at least partially formed as a heat sink, which is arranged in the receiving shaft of the flow channel and partially, in particular with parallel to the longitudinal direction of the flow channel extending cooling fins, is positioned hineinerumblend in the flow channel.
  • the electronic component carrier is arranged in the receiving shaft such that it is arranged to occlude the flow channel on its open side wall and / or its open ceiling wall. An undesirable cooling air flow outlet is avoidable.
  • a particularly noteworthy cooling concept can be made possible by this arrangement, and, moreover, the electronic component carrier can be kept mechanically stable and positioned by the flow channel.
  • the electronic component carrier is arranged engaging in the over the entire length of the receiving shaft between the Strömungskanaleinlassflansch and the Strömungskanalauslassflansch extending wall web.
  • this wall bar is thus also a holder and fixation created, so that the electronic component carrier is positioned in particular slip-proof.
  • the invention relates to an induction hob with an inventive arrangement or an advantageous embodiment thereof.
