  • each radiator block is built of some variant of the radiator element RE or with a combination of various compatible radiator elements RE, for instance those from Figs. 1.2 -1.2 and Figs. 2.1 to 3.

  • openings 8 and chimney 7 or 8 and 10 in some of the variants increases additionally the convective heat emission.
  • radiator elements RE with welded lamellas 3, respectively blocks for radiators consisting of them are of increased periphery.
  • the hot heat-transferring fluid circulates through the interior of the radiator elements, transferring the heat to the walls of the new periphery of the radiator elements. Due to the facts presented above, this heat is conducted to the periphery of the block and emitted in the surrounding space through increased heat-emitting surface. As a result, the external elements, especially the lamellas 3, are of diminished temperature, which is in conformity with the safety requirements.
  • the high temperature of the external peripheral surface of the radiator elements represents a danger if it is touched by users.
  • this surface temperature is controlled by interruption of the welds 5 at appropriate locations, which decreases the conductive heat transfer in the individual areas of welds 5 if necessary.
  • the upper horizontal part of the weld 5 can be an interrupted one, even a spot weld, as a result the heat transfer conducted almost entirely through the interrupted weld 5 experiences difficulties, and that horizontal part of lamellas 3 is heated to a lesser extent, i. e. to a temperature that meets the safety requirements.
  • interrupting the welds 5 (wholly or partially) in the area of lamellas 3 opposite to the upper connection opening 2 eliminates the abrupt overheating in that area of the lamellas 3. This, too, provides conformity with the safety requirements.

Abstract

L'invention porte sur des appareils de chauffage. L'élément radiateur (RE) et les blocs pour radiateur présentent un transfert de chaleur par conduction accru et une émission de chaleur par convection accrue, une fiabilité améliorée et une stabilité mécanique accrue. L'élément (RE) comporte deux enveloppes soudées (1.1, 1.2) et des ouvertures de liaison (2). Une lamelle métallique en forme de U (3) est soudée en T, entièrement ou partiellement, au bord périphérique (4) de sa périphérie. Le soudage (5) est un soudage continu ou partiel, incluant également un soudage par points. Dans l'élément (RE), le bord (4) peut être divisé en deux parties périphériques, la lamelle (3) étant soudée à leurs bords périphériques respectifs (4.1) et (4.2). Ceci forme un canal de transfert de chaleur (7) qui peut constituer une cheminée. Un bloc pour un radiateur comporte 2n éléments, chacune des n lamelles respectives (3n) étant soudée en T, entièrement ou partiellement, aux bords périphériques (4) de deux éléments adjacents. Dans une autre variante, chacune des lamelles (3n) est soudée aux bords périphériques adjacents (4.2n) et (4.1n+1) de deux éléments adjacents (REn) et (REn+1).
