Increasing the heat output of radiators by alternating interruption of the convector sheets or fins

Abstract

Panel radiators also known as flat or plan radiators which have a primarily multiple horizontal interruption and / or slightly offset arrangement.

Description

[0001] The invention relates to panel, flat or planar radiators. State of the art:

[0002] Panel radiators, also known as flat or plan radiators, are state of the art in heating installation.

[0003] Due to the lower flow temperatures sought for overall efficiency, the heat output through convection is reduced. An even lower flow temperature is targeted, particularly through the use of heat pumps.

[0004] This inevitably leads to very small temperature differences between the radiator and the air. This results in lower driving forces and thus slower air speeds. This leads to the formation of undesirable boundary layer thicknesses on the radiator wall. These impede heat transfer. Convector plates or fins in the aforementioned radiators are also known to improve heat dissipation.

[0005] Realized, for example, with radiator type 11 compared to type 10, etc.

[0006] Based on this state of the art, the object of the present invention is: • To improve the heating performance of the radiators by modifying the arrangement of the convector panels. To achieve this, the convector panels are interrupted (slit) horizontally and arranged slightly offset. This breaks up the laminar underlayer at each segment, thus significantly improving heating performance. a. See Fig. Rear view of a Type 11 radiator with convector panels • there is 1 break / cut in the slats • there are 2 bent or unchanged or extended cutting edges • there 3 front of the slats of the convector sheet b. See Fig. Side view of a single cut slat c. See Fig.Top view of a cut slat and, for example, a slat bent together at the top • The interruption still ensures a very simple technical implementation during production. Summary:

[0007] Improvement of heat dissipation by horizontal interruption of the convector sheets to break up the laminar sublayer.

Claims

[1] Panel radiators also known as flat or plan radiators which have a predominantly multiple horizontal interruption and / or slightly offset arrangement. [2] The offset can be made laterally but preferably transversely to the radiator or in a combination of both directions. [3] The offset distance and the distance of the interruption of the convector sheets can vary.
