Definitions

  • the invention relates to a flat electric radiator with at least two heating plates, which are connected by pipe pieces and at least one heating device is provided, which is surrounded by a heating medium and which is arranged between the heating plates and is connected by pipe sections with the heating plates, the Ein or outlet in the heating plates for the heating medium.
  • Electric flat radiators are, for example, from the FR 2 865 527 A1 and the DE 20 2004 004 892 U1 known and show the features of the preamble of claim 1. They have hot plates, which are filled with a heating medium. The heating of the heating medium via the heating device, which is usually a heating element, which is provided with a switching device and a thermocouple. In addition, a controller is provided on which the desired temperature is adjustable.
  • the heater is arranged at multi-layer flat radiators at the lowest point of the radiator between the heating plates.
  • the heating medium surrounds the Heating and heating this, which in turn the heating plates are heated. Since electrical panel radiators unlike conventional hot water radiators, which are connected to the piping system of a building, have no circulation of the heating medium, the heating medium rather “stands” in the radiator, the propagation of heat in the heating medium and thus the heating of the entire radiator very long. In addition, this results in large temperature differences within the individual plates.
  • a very significant advantage is better heat dissipation of the entire flat radiator, when the serving as a forward plate, which is considered a warmer plate, is provided on the side facing the respective space.
  • the defined formation of a flow and a return plate has the advantage to take into account requirements in schools, kindergartens and the like, in which it is desired to arrange the warmer plate on the side facing away from the respective space to reduce the risk of burns. In electric panel radiators this definition of flow and return plate is not feasible due to the non-specified circulation of the heating medium, which is why a substantially uniform heating distribution takes place on both heating plates. As a result, the heat output is reduced.
  • the invention aims to remedy this situation.
  • the invention has for its object to provide a flat electrical radiator, in which a plate serves as a flow and a plate as a return and allows circulation of the heating medium. According to the invention, this object is solved by the features in the characterizing part of claim 1.
  • an electric flat radiator is created, which allows a better heat distribution. Due to the different height of the outlet from the one plate in the direction of the heater in relation to the outlet of the other heating plate after the heater, a defined flow direction of the heated heating medium is caused, which causes a flow function in one heating plate and a return function in the other heating plate. As a result, a better, in particular more uniform heat distribution is caused in the flat radiator, which has a higher heating comfort result. In addition, a temperature congestion in the immediate vicinity of the heating element is prevented due to the circulation of the water obtained, whereby the number of starts and stops of the heating element is reduced, which increases the life of the heating element and the switching device.
  • the support inserts allow a simple and stable connection of the pipe sections to the heating plates. Due to the radial alignment, an increase in the flow is possible, which improves the heating power of the flat radiator.
  • the bore are arranged at most at an angle of 90 ° to each other. This ensures that the heating medium exits in the predetermined direction of the support insert and therefore the intended flow direction is maintained despite the arrangement of several holes.
  • the flat radiator chosen as an exemplary embodiment has two heating plates 1, 2.
  • the front heating plate 1 is welded at its end facing away from the bottom pipe sections 3 with the rear heating plate 2.
  • a heater 4 is provided, which is connected by pipe sections 5 with the heating plates 1 and 2.
  • the heating device 4 consists of a square tube 41, which is penetrated by a heating element 42.
  • the square tube 41 has a connection 43, to which a thermocouple, not shown, or a switching device can be attached. These are provided via a line with a plug that can be plugged into a socket to operate the flat radiator.
  • the square tube 41 is provided with holes 44 on which the pipe sections 5 are arranged. Through the holes 44, the heating medium enters the square tube 41 on or off. In functional ready state of the electrical panel heater, the square tube 41 as well as the heating plates 1 and 2 including the pipe sections 3 and the pipe sections 5 is completely filled with the respective heating medium.
  • the pipe sections 5 are arranged on the heating plates 1 and 2.
  • holes 11, 21 are provided in the heating plates 1 and 2, through which the inlet and outlet of the heating medium in the heating plates 1, 2 can be done.
  • support inserts 6 are arranged in the heating plates. In the exemplary embodiment, three support inserts 6 are provided in each heating plate 1, 2.
  • the support inserts 6 are formed in the manner of a ring.
  • the ring 61 surrounds an opening 62.
  • two radially aligned holes 63 are provided in the ring 61, which cause a connection between the opening 62 and the circumference of the support insert 6.
  • the holes 63 in the support inserts 6 are arranged in the embodiment at an angle of 40 ° to each other; in the extreme case, the holes at most at an angle of 90 ° to each other.
  • the bores 63 are arranged in the ring 61 on the side facing away from the bottom. They are thus oriented upwards.
  • the bores 63 are arranged in the ring 63 on the side facing the bottom. So you are pointing down.
  • the outlet from the rear heating plate 2 in the region of the heating device 4 is therefore arranged lower than the inlet into the front heating plate 1. Due to this arrangement, the heating medium in the front heating plate 1 only has the option to exit upwards from the support inserts 6.
  • the orientation of the bores 63 of the support inserts 6 in the rear heating plate 2 also leads to the cooler heating medium through the downwardly directed - deeper - bores 63 in the support inserts 6 and the pipe sections 5 in the direction of the heater 4 occurs.
  • a circulation of the heating medium in the heating plates 1, 2 caused, which leads to a targeted flow through the panel radiator.
  • the rear heating plate 2 acts as a return plate.
  • a flow or return is caused in the electric flat radiator, although this is not continuously flowed through by a heating medium.
