Definitions

  • the invention relates to an electric storage heater a memory core, electric radiators for heating the Storage core, at least one flow channel, a blower, which causes an air flow to discharge the memory core which promotes at least one flow channel, and one Storage core, the flow channel and the fan receiving Device housing that with inlet and outlet openings for the flow channel is provided.
  • a blower which causes an air flow to discharge the memory core which promotes at least one flow channel, and one Storage core, the flow channel and the fan receiving Device housing that with inlet and outlet openings for the flow channel is provided.
  • this is the flow channel in the Usually deflected several times through the memory core.
  • the air carried by the blower through the flow channel the heat immediately from that delimiting the flow channel Storage core medium occurs and enters from the outlet openings the room to be heated.
  • the training and the course as well as the skillful demarcation of the flow channel Prerequisite for the most uniform possible discharge of the Storage core and thus for an acceptable efficiency of the Storage heater.
  • the invention has for its object a uniform and reliable discharge of the entire memory core and to achieve with relatively little structural effort.
  • the heat can Storage core withdrawn evenly and to the heat exchanger are transmitted from where they are comparatively concentrated area, namely in the area of the air flow exposed heat exchanger surface, in the room to be heated can be dissipated. This allows the flow channel shorten it considerably and structure it accordingly.
  • the coupling agent can be even distributed over the memory core and with its medium inside Be brought in contact. Such coupling means can the heat is similarly light, even from critical corner areas be dissipated like from the middle of a block-shaped Memory core.
  • the memory core itself can just like that Device housing are extremely compact, and the Thermal insulation surrounding the storage core can be according to the thermal Insulation properties can be selected and designed.
  • the degree of coupling between the storage core and the heat exchanger controllable For this purpose, at least one Heat exchanger surface changeable, for example in Device housing can be slidably and / or pivotally arranged. Due to the possibility to change the degree of coupling between Storage core and heat exchanger can be on the otherwise usual continuous or non-continuous fan speed control is dispensed with become. This increases user comfort accordingly, because the discharge can be done at very low Fan speeds without disturbing switching noises relatively accurate by simply changing the degree of coupling or the position of the Regulate the heat exchanger.
  • For changing the position of the at least one heat exchanger surface Serves an actuator that is dependent on a controller from a control deviation, in particular from one Temperature deviation is controlled.
  • Heat exchanger surfaces may interfere with the operation of the fan waived and a convection current over the Heat exchanger surfaces are conducted, which is similar to one static storage heater that dissipates heat from the device and a substantial part of the discharge of the memory core causes.
  • Convection currents conducted through heat exchanger surfaces of the blower and still extends all areas of the Memory core are discharged evenly.
  • the Heat exchanger on a holder made of a material with a high thermal expansion coefficient arranged so that the degree of coupling between the storage core and the heat exchanger varies depending on the temperature of the bracket is.
  • a heat exchanger only on one side, for example below or arranged above the memory core.
  • At least one layer of flexible Have heat transfer material in a border zone between the storage core and the heat exchanger, for example at the Bottom of the memory core is arranged.
  • flexible A mat is particularly suitable for heat transfer material Metal wool.
  • the storage core on the heat exchanger is thereby allows the memory core through box or cassette-like metal container is formed with a Melted salt or salt mixture are filled.
  • the molten salt or salt mixture has excellent heat storage properties.
  • the molten salt and salt mixture nestles relatively homogeneously and intimately on the heat-dissipating metal container walls, so that at their ends and transfer points to the heat exchanger and to the subsequent ones parallel to the heat exchanger Container walls provided a high heat potential becomes.
  • Embodiment of the new electric storage heater encloses a device housing with thermal insulation a receiving chamber for a memory core 2.
  • the Storage core are electric radiators 3 for heating the Storage core arranged in an even distribution.
  • the Memory core 2 is a more compact, essentially closed Block trained. Part of the memory core has broken away shown so that a series of housing openings 4th becomes visible through the convection currents from the Housing interior into the room to be heated to the outside emerge and for a certain static discharge of the Storage core can worry.
  • a relatively wide flow channel 5 extends from an inlet panel 6 provided with inlet openings starting from a bottom housing chamber to one arranged on the opposite side of the housing Outlet opening 7. Behind the inlet panel 6 is in Flow channel 5, a blower 8 arranged, the air flow from the inlet side through the flow channel 5 to Exit opening 7 promotes to discharge the memory core.
  • the flow channel 5 is located on the storage core 2 facing side by one described in Embodiment designed as a finned tube heat exchanger Heat exchanger 10 limited.
  • the heat exchanger 10 is on his the inlet panel 6 adjacent end via a pivot bearing 11 supported and can not with the help of one in the drawing shown swivel drive in different swivel positions to be brought.
  • Heat transfer mat 12 made of metal wool arranged with the heat exchanger 10 folded up under the pressure of the can flexibly compress adjacent heat exchanger surface.
  • the heat transfer mat 12 creates one excellent heat transfer between the heat exchanger 10 and the heat transfer surfaces of the memory core 2.
  • In the memory core 2 are heat-conducting coupling elements in the form of vertical running metal walls 14, which with the Storage medium 2 are in intimate contact.
  • About these Coupling elements 14 is the heat directly from the Memory core 2 discharged down and over the heat-transferring flexible metal wool mat 12 on the neighboring, upper heat exchanger surface transferred.
  • the ones from Storage core 2 to the heat exchanger 5 transferable amount of heat can be recognized by changing the swivel position of the Change heat exchanger 5.
  • Coupling means for transporting the heat out of the storage core 2 into the border zone between mat 12 and heat exchanger 5 be used.
  • the exemplary embodiment is the heat exchanger 5 'via a Push rod 20 opposite the transfer surface on the underside of the memory core 2 shown as a block.
  • the Actuator of the push rod 20 is in the schematic Representation according to FIG. 2 not shown; such actuators are, for example, in the form of spindle drives or Rack and pinion drives are known in various designs.
  • Fig. 3 shows a perspective view Embodiment of the storage heater, in which a top wall of the housing 1 is omitted and the upper end of the Storage core and the surrounding thermal insulation 15 are exposed.
  • the memory core shown in Fig. 3 contains cassette-shaped metal container 14 'with a molten salt or salt mixture are filled as a storage medium.
  • Such Storage media have excellent storage properties and ensure excellent heat transfer to the bounding walls of the metal container 14 '.
  • the flow channel above the Storage core and / or along one of the housing side walls run.
  • the inlet side shown in FIG. 1 is recommended Arrangement of the blower 8; on the other hand, the blower can also on the outlet side near the outlet panel 7 be arranged.
  • the blower In the area of the movable ends of the Heat exchanger 5 can be attached to flexible aprons the flow channel in the area of the transition points when moving seal the heat exchanger 5.
