[0017] Below, details and embodiments of the invention are explained with reference to merely schematic drawings.

DETAILED DESCRIPTION

[0023] In FIG. 1, a ceiling radiator 01 is illustrated which is disposed in a room 14 in a ceiling area 12. Ceiling radiator 01 has a star-shaped cross-sectional shape with five star tips 02, two converging radiant panels 04 forming one star tip 02 in each case. Star tips 02 are connected to a flow tube 03 in center M of the star-shaped cross-sectional shape.

[0024] During operation of ceiling radiator 01, a cooling or heating liquid can flow through flow tube 03 along the x-axis such that ceiling radiator 01 emits or absorbs heat radiation at star surfaces 15.

[0025] A suspension 08 from ceiling 16 is disposed at a star tip 02 such that the five star tips 02 realize a larger radiating surface 15 in a floor direction 10 than toward ceiling 16. In this case, especially radiant panels 04 are acting with illustrated heat radiation 13 in floor direction 10 to, for example, heat or cool a work or living area at floor 11. Remaining radiant panels 04 in the direction of ceiling 16 act via reflections with less intensity than radiant panels 04 on floor 11.

[0026] Alternatively, suspension 08 could be disposed on flow tube 03. However, in this case, radiating surface 15 in floor direction 10 would be reduced compared to a suspension 08 at one of star tips 02.

[0027] Flow tube 03 is preferably circular in shape such that, compared to angular flow tubes, it can easily be connected to fluid connections. In an alternative embodiment, flow tube 03 can also have a rectangular shape, for example with side surfaces corresponding to the number of star tips 02. It would also be possible that radiant panels 04 themselves form a star-shaped flow tube.

[0028] Furthermore, in addition to flow tube 03 in center M of star 01, a flow tube may be disposed within one of star tips 02. Thereby, the flow rate can be increased while the flow velocity remains the same or the emitted or absorbed radiant power can be increased.

[0029] Star tips 02 in FIG. 1b are preferably disposed in such a manner that outer corners 05 of five star tips 02 are uniformly distributed on a first circle 17 and inner corners 06 at the joint of several star tips 02 with flow tube 03 in center M of star 01 are uniformly distributed around central point M of the cross-sectional shape on a second circle 18 and that the five star tips 02 form isosceles triangles.

[0030] The triangles have a preferably same inner angle ? between radiant panels 04. Preferably, angle ? of star tips 02 at outer corners 05 is 16? to 38?, in the case at hand 24?. Furthermore, the outer diameter of the flow tube is 25% to 42%, in the case at hand 38%, of the circle diameter around outer corners 05.

[0031] An angle ? is also preferably designed uniformly along the circumference, the combination of angles ? and ? increasing heat radiation 13 in floor direction 10.

[0032] Moreover, angles ? and ? are preferably realized in such a manner that liquid, for example condensate, does not collect at inner corners 06, but is dischargeable in floor direction 10.

[0033] In the case of a desired irregular realization of angles ? or ?, it is preferred that a surface 15 of radiant panels 04 which is as large as possible is inclined at an angle which is as obtuse as possible relative to floor direction 10, wherein the surfaces preferably do not overlap. For example, individual star tips 02 can be increased to avoid overlapping.

[0034] Preferably, several star tips 02 and/or the at least one flow tube 03 is/are producible as an extruded profile, preferably made of aluminum or plastic. In this way, the seamless cross-sectional shape illustrated in FIG. 2a results. In this case, ceiling radiator 01 is made of one piece 07 in the cross-sectional direction, as illustrated in FIG. 2b. End parts or connecting parts, which are not shown in the sectional representation, can, of course, be provided by separate components and connected to the one-piece profile component. Advantageously, therefore, ceiling radiator 01 has no weld seams at inner corners 06 in the cross-sectional direction and the heat transmission from flow tube 03 in center M to star tips 02 can be improved. The extruded profile can have a length of 1 m to 2 m and up to 5 m in the x direction.

[0035] Ceiling radiator 01 described thus far can be altered or modified in a variety of ways without departing from the idea of the invention. Thus, for example, a larger number of star tips 02 may be used or several ceiling radiators 01 having differently disposed star tips 02 can be used in order to focus the heat radiation on a specific area at floor 11 of room 14.
