Abstract
The invention relates to a radiation heater with a radiant tube surrounded by a housing which has a reflector region guiding the heat radiation downwards. The radiation heater can also be used in low spaces due to the fact that the structure of the upper reflector region and/or lateral reflector regions adjacent thereto and/or radiation surfaces of the radiant tube is such that the heat radiation emerging from the housing has a distribution curve lowered at the centre below the housing and raised in relation thereto on both sides.

R~dia~lt heat heater The invenhon relates to a radiant heat heater with a housing that at least partially su~rounds at least one radiant tube, that ~eatures an upper reflect~r area ~at ~l~fl~cts ~e radia~lt heat downward and that is open a~ ~e bottom for the r~ tit~n of heat.
Such radiant heat heaters ~i~hn~ h themsel~ves by their low proportion of wnvection heat and their relati~ely cost-effecnve ener~y usage. But, since the i~l~C,A)s;~c r~ tio~ of heat onto the head of a human is not well tolerated, the use of radiant heaters up until no~r has been l~mited to rooms that are more than e.g. 4 meters high, so that hall-like meeting or work rooms are particularly considered as areas o~ app~ $ion Wi~ re~ard to more ~et~i embo~limPnt.~, reference is made to the ~n~book for He~tinE and Climate Technology (Tac~ Pnbuch fuer Heizung + ~lim~technik) 92/93, page 362 ff.
The invention has the basic task of prov~ding ~ radiant heat heater of the initially indicated type which also provides an acceptable se~s;ltion of heat in low height rooms.
Thc ~ is a~,o~-~rlich~ by meuls ofthe c~ t~ri~r~ of cl~im 1. According to that, it is provided that the upper reflector area and/or ti c jwc~posed lateral reflector area and/or the r~ tinp surfaces of the radiant tube are de~ie~- d in such a way ~a~ the heat radiation -', ~ .
leaving ~e housing eYhil~its a ~li~b~ cuI-re with a shape that is dcpr~se~ in the center under the housing and is relatively r~sed on bo~ ~1des. ~Vith these mewres the high cen~al vertical radiant heat por~on of conven~;on~ t heat heaters is ~ .sed, and is made usefill in areas of g~eater angles of rodi~tir~n rela~ive to the ver~cal. The heat ~ii~ih~ on thus produc~ed avoids r~ hne the head ln a m~nner ~at is too intensive. The radiant heat heater will thus be usefill for room heights u~der 4 meters all the ~vay down to e.g. 2.80 meters. Suitable distribution cu~es can be ac~ieved with the in~liC~te~ ~LIe~Ur~iS, ~~penf~i on the type and ~eQIr ~try of the room and lhe arrangement of the radiant heat heater, The dist:nbution curve can be dete~tnin~ e.g. by ~e g~metry of the radiant tube, that is, for example, by having lateral sections of the ra~i~tine surface that are larger than ~e lower and the upper sectionc In this c~e the design can be such that the cross sec~on of the radiant tube is trape70i~1 in shape, with ~e base on top or on the bottom, oval ~th the larger mPter a directed ver~cally, tri~lar wit:h a base chat is on top or ~n the bottom, or rectangular with vertically directed longitudinal sides. If it is pronded ~at the radiant tube is selectively coated at least in sectionC, ~en the r~ ting portio~s can additioD~lly be suitably defined by va~ying the degree of ~n~niS~inD.
A fur~er measure to establish the distribution cu~ve of the radiated heat, ~ ich can possibly be carried out in addition to other measures, is to have a r~flecting reflector ~1ement a~anged under the radiant tubc. The design can ~ereby be of such a nature ~at the lower reflector element features lateral deflec~on s~ .s that deflect the imr~ctir~ heat radiation toward t:he sides ess~lti~11y symmetrically, or ~at ~e lower reflector element is ~lesiEnP~l in the form of - -z :' ' 1 strips. The vertical por~on can be d~wod rr~tic~lly as desired along the width of the stnps, so ~hat a desigrl cf ~he radiant heat heater is achieved such that it is adv~n~ous for low room hPi~tC
The deflection o~ tihe radiant heat can be fi~er varied by having ~e lateral reflector areas l vertically. In this ~;vay the radiant tube can also be optically shielded, so that the e~ance of the radiant heat heater is fa~rorable. ~e distribution of ~e radiant heat can fi~rthP~ore be influenced by having the reflector areas desi~Pd ~ vapor deposited ~lass stnps. ~ greater or lessor portion of the radiMt heat can be reflPcted ~1Pp~ ine on the intensity of the ~Japor deposit or coa~ng of t}.e glass strips.
A suitable distribution curre with decreased v~rtical heat rad1~tion in the central area can be achieved in particular in conjunction with the prwiously indicated measures, in that the upper reflector area features sec~ion~ that drop off obliquely in cross section on both sides toward l:he edge, or are curved.
The ~n~ention is e~rl~ined ~n more detail in the following on the basis of an e~.emrllfied embodiment with reference to the drawings. Shown are:

The selective coating S of the radiant tube g can be used to vaIy the sq~ sr~ loa~ ~e lateral areas of thc radian~ tube 8. ~rhe la~eral sur~aces of the radiant tube 8 can thereby be desi~P~l to be larger rela~ive to the upper and lo~ver portions of the r~ tin~ surfaces 4, in order to achieve ~ coLLc~ondingly greater lateral r~liptio~ The .~.. .. .
