Abstract

The present invention relates to a cooler consisting of a bearing part (1), which is provided with a system of through-holes arranged one above the other and intended for fastening ends of co-axially arranged U-shaped cooling pipes (2). The U-shaped cooling pipes are provided with a spiral offset (3), wherein the depth (h2) of the spiral offset (3) performed on an intermediate cooling pipe (2a) is always less than the depth (h1) of the spiral offset (3) performed on the cooling pipe (2) abutting inwardly the intermediate cooling pipe (2a), and always greater than the depth (h3) of the spiral offset (3) performed on the cooling pipe (2) abutting outwardly the intermediate cooling pipe (2a), wherein each cooling pipe (2, 2a) has constant diameter all over its length.

Description

ChladičCooler

Oblast technikyField of technology

Vynález se týká chladiče určeného zejména pro motorová vozidla.The invention relates to a radiator intended in particular for motor vehicles.

Dosavadní stav technikyPrior art

Vedení toku plynu a jeho distribuce v současných svazcích chladičů, se soustředně uspořádanými chladicími trubkami majícími tvar písmene U, je v trubkách nerovnoměrně rozložené. To vede k vyřazení optimalizovaného provozu a poklesu hodnoty tlaku v zařízení.The gas flow guide and its distribution in the current cooler bundles, with concentrically arranged U-shaped cooling tubes, are unevenly distributed in the tubes. This leads to the elimination of optimized operation and a decrease in the pressure value in the device.

Příkladem takového provedení je např. řešení spisu CN 201221 907Y, v němž je chladič sestaven z trubek tvaru písmene U, v jejichž povrchu jsou vytvořeny šroubovice s konstantním stoupáním a konstantní hloubkou. Dalším obdobným příkladem je řešení spisu DE 2007013302 AI, v němž je chladič řešen soustavou trubek tvaru písmene U s hladkým povrchem.An example of such an embodiment is, for example, the solution of CN 201221 907Y, in which the cooler is composed of U-shaped tubes, in the surface of which helices with a constant pitch and a constant depth are formed. Another similar example is the solution of DE 2007013302 A1, in which the cooler is solved by a system of U-shaped tubes with a smooth surface.

Podstata vynálezuThe essence of the invention

Výše uvedené nedostatky snižuje chladič, sestávající z nosné části, která je opatřena soustavou nad sebou uspořádaných průchozích otvorů, pro upevnění konců soustředně uspořádaných chladicích trubek majících tvar písmene U a opatřených spirálovým prolisem, podle tohoto vynálezu, jehož podstata spočívá v tom, že hloubka spirálového prolisu vytvořeného na mezilehlé chladicí trubce je vždy menší než hloubka spirálového prolisu vytvořeného na k mezilehlé chladicí trubce vnitřně přilehlé chladicí trubce a vždy větší než hloubka spirálového prolisu vytvořeného na k mezilehlé chladicí trubce vně přilehlé chladicí trubce, přičemž každá z hladících trubek má po celé své délce konstantní průměr.The above-mentioned drawbacks are alleviated by a cooler consisting of a support part provided with a set of superimposed through holes for fixing the ends of concentrically arranged U-shaped and spiral-shaped cooling tubes according to the invention, the essence of which is that the depth of the spiral the recess formed on the intermediate cooling tube is always less than the depth of the spiral recess formed on the intermediate cooling tube internally adjacent to the cooling tube and always greater than the depth of the spiral recess formed on the intermediate cooling tube outside the adjacent cooling tube, each of the smoothing tubes length constant diameter.

Výhodou této konstrukce je optimalizovaný provoz bez poklesu hodnoty tlaku v zařízení.The advantage of this design is optimized operation without a drop in the pressure value in the device.

Objasnění výkresuExplanation of the drawing

Příklad jednoho možného provedení chladiče podle tohoto vynálezu je v bočním pohledu znázorněn na připojeném Obr. 1.An example of one possible embodiment of a cooler according to the invention is shown in a side view in the attached FIG. 1.

Příklady uskutečnění vynálezuExamples of embodiments of the invention

Jak je patrné z Obr. 1 chladič sestává z nosné části 1, která je opatřena sudým počtem nad sebou uspořádaných průchozích otvorů. V daném příkladném provedení je v nosné části 1 uspořádáno šest otvorů (je ale možné v nosné části vytvořit též osm, deset nebo více párových otvorů), pro upevnění konců tří soustředně uspořádaných chladicích trubek 2 majících tvar písmene U a opatřených spirálovým prolisem 3.As can be seen from FIG. 1, the cooler consists of a support part 1, which is provided with an even number of through-holes arranged one above the other. In this exemplary embodiment, six holes are arranged in the support part 1 (but it is also possible to make eight, ten or more pairs of holes in the support part) for fixing the ends of three concentrically arranged U-shaped cooling tubes 2 and provided with a spiral recess 3.

Hloubka h2 spirálového prolisu 3 vytvořeného na mezilehlé chladicí trubce 2 a chladiče je vždy menší než je hloubka hl spirálového prolisu 3 vytvořeného na k mezilehlé chladicí trubce 2 a vnitřně přilehlé chladicí trubce 2 a vždy větší než hloubka h3 spirálového prolisu 3 vytvořeného na k mezilehlé chladicí trubce 2 a vně přilehlé chladicí trubce 2, přičemž každá z chladicích trubek 2, 2a má po celé své délce konstantní průměr.The depth h2 of the spiral recess 3 formed on the intermediate cooling tube 2 and the cooler is always less than the depth h1 of the spiral recess 3 formed on the intermediate cooling tube 2 and the internally adjacent cooling tube 2 and always greater than the depth h3 of the spiral recess 3 formed on the intermediate cooling tube 2. tube 2 and an adjacent cooling tube 2, each of the cooling tubes 2, 2a having a constant diameter along its entire length.
