Definitions
- the invention relates to a radiant heat heater with a housing which at least partially surrounds at least one radiant tube and which has an upper radiation region which directs the heat radiation downwards and is open at the bottom for the heat radiation.
- Such radiant heating systems are characterized by a low convection heat content and relatively economical energy consumption.
- intensive heat radiation has an intolerable effect on the human head
- use in previous radiant heating systems was limited to greater room heights than e.g. 4 meters, so that, in particular, hall-like lounge or work rooms could be used.
- the invention has for its object to provide a radiant heat heater of the type mentioned, which conveys a pleasant sensation of heat even in lower rooms.
- This object is achieved with the features of claim 1.
- the upper reflector region and / or the lateral reflector regions and / or radiation surfaces of the radiant tube adjacent to it are designed in such a way that the heat radiation emerging from the housing has a distribution curve with the central region below the housing and increased on both sides relative to it History.
- the distribution curve can e.g. be determined by the geometry of the jet pipe, for example in that the lateral sections of the radiation surface are larger in cross section than the lower and upper ones.
- the design can be such that the cross-section of the jet pipe is trapezoidal with a base lying at the top or bottom, oval with a large diameter oriented vertically, triangular with a base lying above or below or rectangular with vertically oriented long sides. If it is provided that the beam tube has a selective coating at least in sections, the radiation components can additionally be suitably determined by varying the degree of transmission.
- a reflective lower reflector element is arranged under the beam pipe.
- the design can be such that the lower reflector element has lateral deflection surfaces which deflect the incident heat radiation essentially symmetrically to the side, or that the lower reflector element is designed as a horizontal strip.
- the vertical portion can practically be reduced as desired over the width of the strip, so that such a configuration of the radiant heat heating is advantageous for low room heights.
- the control of the heat radiation can also be varied in that the lateral reflector areas are aligned vertically. In this way, the radiant tube can also be optically shielded, so that the appearance of the radiant heating is favored.
- the distribution of the thermal radiation can also be influenced by the fact that reflector regions are designed as vapor-coated glass strips. Depending on the strength of the vaporization or coating of the glass strips, a more or less large proportion of the heat radiation can be reflected.
- a suitable distribution curve with reduced vertical heat radiation in the central area can be achieved in that the upper reflector area in cross-section has sloping or curved sections on both sides towards the edge.
- Fig. 1 shows a cross section of a radiant heating
- Fig. 2 distribution curves of the heat radiation of two variants of this radiant heating.
- the radiant heat heater 10 shown in FIG. 1 has a housing 9 in which a radiant tube 8 extending perpendicular to the plane of the drawing is arranged between the lateral housing boundaries.
- the housing 9 Above the jet pipe 8, the housing 9 has an upper reflector region 1 with a central horizontal section and adjoining sections which are inclined downwards towards the edge. The inclined sections are delimited at their free end by vertically downwardly extending side reflector elements 2. Insulation means 7 for suppressing heat losses are provided above the upper reflector region 1, and the housing 9 is closed on its upper side with a housing cover 6.
- a lower reflector element 3 is arranged vertically below the jet pipe 8 and has essentially the shape of an angle or triangle in cross section with the tip pointing upwards and the base lying below.
- the cross section of the jet pipe 8 has a large proportion of steep radiation surfaces, which are additionally provided with a coating 5. 1 shows a trapezoidal cross section with the base side at the top.
- the heat radiation emerging from the radiant tube 8 can be carried out in a variety of ways Reflection and / or transmission can be influenced in order to reduce the intensity of a heat radiation directed vertically downward from the jet pipe 8 and to define heat radiation radiated to the side at a radiation angle ⁇ (see FIG. 2) in a defined manner.
- Reflection and / or transmission can be influenced in order to reduce the intensity of a heat radiation directed vertically downward from the jet pipe 8 and to define heat radiation radiated to the side at a radiation angle ⁇ (see FIG. 2) in a defined manner.
- the selective coating 5 of the jet pipe 8 the radiation emerging from the lateral areas of the jet pipe 8 can be varied.
- the lateral surfaces of the beam pipe 8 can be made larger relative to the upper and lower portions of the radiation surface 4 in order to achieve a correspondingly greater lateral radiation.
- the radiation emerging from the beam pipe 8 is directed onto the lateral reflector areas 2 and from there reaches the space below the housing 9 at a corresponding angle.
- a portion of the heat radiation emerging downwards from the jet pipe 8 is directed to the side surfaces of the lower reflector element to the side into the space below the housing 9.
- the measures described result, for example, in a distribution curve b according to FIG. 2.
- the radiation intensity or irradiance E is significantly reduced in this distribution curve, while maxima of the distribution curve occur in the subsequent angular range at approximately 30 ° .
- the lower reflector element 3 is removed or replaced by another reflector element, which can be designed, for example, as a horizontal strip that is completely or only partially reflective and partially permeable, the vertical portion of the distribution curve is weakened less, as the distribution curve a shows . In both cases, the vertical component is used in favor of the angular abundant radiated heat radiation is reduced, the efficiency is practically hardly reduced.
- the upper reflector region 1, the lateral reflector region 2 and the lower reflector element 3 Due to the geometry and coating of the beam pipe 8, the upper reflector region 1, the lateral reflector region 2 and the lower reflector element 3, suitable distribution curves can be generated by appropriate variation, with a greater reduction in the heat radiation in particular for small room heights in the middle range is advantageous.
- the optics of the radiant heating can also be varied, so that they e.g. can also be used as a built-in, annex or suspended radiation body in offices or waiting rooms.
