Opfindelsen angår en radiator med indbyrdes parallelt anbragte fladrør, som et stykke fra deres ender er tilsluttet samlerør til frem- og tilbageløb.The invention relates to a radiator with flat pipes arranged in parallel with one another, which a connecting pipe for reciprocating flow is connected some distance from their ends.

En sådan radiator kendes fra DE-OS 25 40 202.Such a radiator is known from DE-OS 25 40 202.

5 I et centralvarmeanlæg med en radiator af denne art strømmer varmt vand igennem radiatoren med en hastighed, der blandt andet afhænger af den valgte dimensionering af rørene. Radiatorens termiske træghed og varmeafgivelse afhænger også af det varme 10 vands strømningshastighed. Af fremstillingstekniske grunde har man hidtil anvendt fladrør, hvor forholdet mellem fladrørenes vandindhold og varmeflade eller forholdet mellem det indvendige tværsnitsareal og rørets omkreds har været relativt stor.5 In a central heating system with a radiator of this type, hot water flows through the radiator at a speed that depends, among other things, on the chosen dimensioning of the pipes. The thermal inertia and heat dissipation of the radiator also depend on the flow rate of the hot water. For manufacturing reasons, flat pipes have hitherto been used, where the ratio between the water content of the flat pipes and the heating surface or the ratio between the inner cross-sectional area and the circumference of the pipe has been relatively large.

15 Nærværende opfindelse tager sigte på at tilveje bringe en radiator, der med henblik på en bedre udnyttelse af den forhåndenværende energi, eller med henblik på at spare energi, har mindre termisk træghed og bedre varmeafgivelse som følge af større strømnings-20 'hastighed af varmeraediet.The present invention aims to provide a radiator which, in order to make better use of the available energy, or in order to save energy, has less thermal inertia and better heat dissipation due to greater flow rate of the heating radius. .

Dette opnås ifølge opfindelsen ved, at fladrørene har en mindste-vægtykkelse på 1,25 mm, og at forholdet mellem det indre tværsnitsareal, målt i mm , og den ydre røromkreds, målt i mm, af fladrørene 25 er mindre end eller lig med 2,5 mm.This is achieved according to the invention in that the flat pipes have a minimum wall thickness of 1.25 mm and that the ratio between the inner cross-sectional area, measured in mm, and the outer pipe circumference, measured in mm, of the flat pipes 25 is less than or equal to 2 , 5 mm.

I det følgende beskrives en udførelsesform for opfindelsen nærmere under henvisning til tegningen, hvor fig. 1 viser et billede af en radiator set 30 forfra, og fig. 2 et lodret snitbillede efter linien I-I i fig. 1 i større målestok.In the following, an embodiment of the invention is described in more detail with reference to the drawing, in which fig. 1 shows a front view of a radiator, and fig. 2 is a vertical sectional view along the line I-I in FIG. 1 on a larger scale.

Den i fig. 1 viste radiator har fem fladrør 1, som med lille afstand er anbragt indbyrdes parallelt 35 og vandret i ét fælles plan, og på deres bagside, etThe device shown in FIG. 1 has five flat tubes 1, which are arranged at a small distance parallel to each other 35 and horizontally in one common plane, and on their rear side, a

Claims

151159 piece from the ends of the flat pipes, is connected to vertical manifolds 2 for reciprocating. Each flat pipe 1 is connected to the same collector ear 2 by means of two connections 3, one of which lies in the vicinity 5 of the upper edge of the flat pipe and the other lies near the lower edge of the flat pipe, so that the flat pipes can be vented and emptied without difficulty. Each manifold 2 has a connection 4 for inlet and outlet for a heating medium.

The device shown in FIG. 2 through the flat tube 1 shows that the width of the inner cross-sectional area 5 is relatively small in relation to the length. The free width of the flat pipe 1 must be 3-5 mm at an externally measured height of the flat pipe of approx. 70 mm. The flat pipe 15 1 has a wall thickness of 1.25 mm, but not more than 2.0 mm. In the case of this extremely flat pipe, the ratio of the inner cross-sectional area 5, measured in mm, to the outer pipe circumference, measured in mm, is less than or equal to 2.5 mm. Calculated per. pipe length unit, the same value 20 applies to the ratio between the water volume of the flat pipe 1 and its external heating surface. A smaller value here means, in comparison with the larger pipe cross-sections of known radiators, that the heating surface corresponding to a given volume of water is larger, and that the heat output of the radiator is therefore better. Since the flat pipe 1 on the other hand contains less water, which, however, flows through at a higher speed, the thermal inertia of the radiator is considerably less * This dimensioning of the flat pipe 1 thus enables various advantages in order to achieve a better energy utilization. Radiator with flat pipes (1) arranged parallel to each other, which a connecting pipe (2) is connected to their return and return for their return, characterized in that the flat pipes have a minimum wall thickness of 1.25 mm , and that the ratio between the inner 2 cross-sectional area (5), measured in mm, and the outer pipe circumference, measured in mm, of the flat pipes (1) is less than or 5 equal to 2.5 mm.
