Oblasť technikyTechnical field
Vynález sa týka vložky na špirálu najmä kvapalinového vyhrievacieho telesa ako napríklad olejového radiátora, ktorá je výhodne vyrobená z teflonu.The invention relates to a spiral liner, in particular a liquid heater such as an oil radiator, which is preferably made of Teflon.
Doterajší stav technikyBACKGROUND OF THE INVENTION
V súčasnosti sa do kvapalinových vyhrievacích telies s elektrickou vyhrievacou špirálou montujú špirály rôznej konštrukcie. Keď je teleso dlhšie respektíve štíhlejšie, dochádza k deformácií tohto telesa a potom sa opiera o vnútornú stenu vyhrievacieho telesa, alebo dôjde ku kontaktu vlastnej konštrukcie špirály. V iných prípadoch sa po zapnutí špirála rozochveje, pričom môže vydávať doprovodný nežiaduci zvukový efekt. Ďalším nežiaducim efektom je vibrovanie voľného konca špirály pri preprave, čím môže dôjsť k poškodeniu zvarov na telese špirály a príruby. Aby sa predchádzalo týmto nežiaducim efektom, tak sa na opačnom konci od elektrického napájania špirály, v konštrukcii plášťa vyhrievacieho telesa vytvorila oporná konzola, ktorá podopiera voľný koniec špirály. Takto riešená konštrukcia podpery voľného konca špirály nesie so sebou zvýšené náklady na výrobu a montáž opornej konzoly v telese špirály. Iným riešením, ktoré odstráni deformáciu špirály, čiže jej ohyb, je osadenie špirál menšej dĺžky z obidvoch strán vyhrievacieho telesa, čo tak isto nesie so sebou zvýšené výrobné náklady, ale neodstraňuje prípadné chvenie špirály.At present, spirals of different design are mounted in liquid heating elements with an electric heating coil. When the body is longer or leaner, the body deforms and then rests on the inner wall of the heater, or the spiral structure itself contacts. In other cases, when the spiral is turned on, it vibrates and may give an accompanying undesirable sound effect. Another undesirable effect is the vibration of the free end of the coil during transport, which may damage the welds on the coil body and the flange. In order to prevent these undesirable effects, a support bracket has been formed at the opposite end of the electrical supply of the coil in the housing structure of the heater, which supports the free end of the coil. The design of the free end of the helix thus designed entails increased costs of manufacturing and mounting the support bracket in the helix body. Another solution that removes the deformation of the spiral, i.e. its bending, is to fit the spirals of a smaller length from both sides of the heater, which also entails increased production costs, but does not eliminate any spiraling of the spiral.
Podstata vynálezuSUMMARY OF THE INVENTION
Uvedené nedostatky odstraňuje riešenie opísané v tomto vynáleze, ktorého podstata spočíva v tom, že medzi časti do tvaru U zohnutej špirály je situovaná aspoň jedna vložka. Táto vložka má tvar H, pričom vybrania na uloženie špirály sú konkávne s tvarom zodpovedajúcim priečnemu rezu špirály. Vzdialenosť medzi základňami zodpovedá vnútornému rozmeru vyhrievacieho telesa. Odstup špirály od steny vyhrievacieho telesa je daný rozmerom stojky na zabránenie dotyku špirály s vnútornou stenou vyhrievacieho telesa a tým zničeniu plášťa vyhrievacieho telesa a špirály. Medzi stojkami sa nachádza mostík, na zabránenie vzájomného dotyku častí špirály, medzera medzi časťami špirály je daná hrúbkou mostíka. Vložka je vyrobená z elektricky nevodivého materiálu, pričom fyzikálne vlastnosti tohto materiálu sa vplyvom teploty nemenia. Vo výhodnom uskutočnení je vložka vyrobená z teflonu.The above-mentioned drawbacks are overcome by the solution described in the present invention, which is based on the fact that at least one insert is situated between the U-shaped parts of the bent spiral. The insert is H-shaped, the recesses for receiving the helix being concave with the shape corresponding to the cross-section of the helix. The distance between the bases corresponds to the internal dimension of the heater. The distance of the coil from the wall of the heater is determined by the dimension of the prop to prevent the coil from contacting the inner wall of the heater and thereby destroying the heater shell and the coil. There is a bridge between the uprights to prevent the spiral portions from touching each other, the gap between the spiral portions being determined by the thickness of the bridge. The insert is made of an electrically nonconductive material, the physical properties of which do not change due to temperature. In a preferred embodiment, the liner is made of Teflon.

Vo výhodnom uskutočnení je vložka vyrobená z teflonu.At least one insert is situated between the U-shaped bent spirals. This insert has an H-shape, wherein the spiral recesses 1 are concave with a shape corresponding to the cross-section of the spiral. The distance 3 between the bases 2 corresponds to the internal dimension of the heater. The distance of the coil from the wall of the heater is determined by the dimension of the prop 4 to prevent the coil from contacting the inner wall of the heater.

Priemyselná využiteľnosťIndustrial usability
Vložka na špirálu najmä kvapalinového vyhrievacieho telesa ako napríklad olejového radiátora, ktorá je výhodne vyrobená z teflonu, sa v procese montáže situuje na vopred dané miesto na špirále tak, že sa zamedzí akémukoľvek dotyku špirály s plášťom vyhrievacieho telesa a taktiež, aby sa špirála vlastným ohybom nedotýkala sama seba. Tým sa predíde prepaľovaniu plášťa vyhrievacieho telesa a taktiež sa predíde zničeniu špirály. V druhom prípade vložka zamedzí rozochveniu špirály, čím sa zamedzí tvorbe rušivého zvuku pri zohrievaní a chladnutí špirály. V treťom prípade sa zabráni nežiaducim vibráciám telesa špirály pri doprave výrobku k zákazníkovi a tým jej prípadnému poškodeniu.The spiral liner, in particular of a liquid heater such as an oil radiator, which is preferably made of Teflon, is located in the assembly process at a predetermined location on the spiral so as to prevent any contact of the spiral with the heater housing and also to spiral itself she didn't touch herself. This prevents firing of the heater shell and also prevents the spiral from being destroyed. In the latter case, the liner prevents the spiral from agitating, thereby avoiding disturbing sound when the spiral is heated and cooled. In the third case, unwanted vibration of the spiral body is prevented when the product is conveyed to the customer and thereby potentially damaged.
