Abstract
The invention relates to a metal side plate for a radiator, in particular a tubular radiator, such as those found in motor vehicles with combustion engines. According to the invention, the metal side-plate (20) is secured to securing points (13) on both sides on the collecting tubes (12) and a longitudinal slot (21) is introduced into the metal side-plate on at least one side in the region of the fixing. The fixing points (13) on the metal side plates (20) are embodied on collecting tubes (12) on one side of the longitudinal slot.
Description
Technical Field
The invention relates to a side panel for radiators, in particular tube radiators, which are used, for example, in motor vehicles with internal combustion engines.
Background
Such radiators have a radiator core in which the tubes extend in the longitudinal direction, while heat exchange surfaces are formed between the tubes. The radiator core extends longitudinally between the two headers and is traversed by cooling air in a transverse direction opposite thereto. The radiator core is here closed at the upper and lower part by side plates, which likewise extend between the headers and are fixed to the headers at fixing locations.
When the running temperature of the tubular radiator fluctuates, the lengths of the tube and the heat exchange surface change, so that when the running temperature of the tubular radiator fluctuates, the lengths of the tube and the heat exchange surface change, and the side plate is influenced by the thermal tensile stress. At the same time, uneven thermal expansion and contraction occurs between the side plates and the edge areas of the radiator core due to uneven material and heating. This uneven thermal expansion results in lateral and longitudinal forces between the heat sink core and the side plates, creating stresses in the attachment areas.
Disclosure of Invention
The invention aims to provide a side plate, which has a structure that can avoid the stress generated in the transverse direction of the extension of the side plate due to different thermal expansion and contraction of the side plate and a radiator core.
This object is achieved according to the side panel described below.
The radiator, in particular a tube radiator, has a cooling body which extends in the longitudinal direction between two lateral collecting main. The cooling body is enclosed by a side plate or a pair of side plates arranged on both sides of the cooling body and extending in the longitudinal direction between the headers. The side plate is fixed to a collecting main at the fixing point or fixed to the collecting main at two sides, and at least one side is provided with a longitudinal groove in the fixing area, when the longitudinal groove is formed on the side plate, the fixing point of the side plate on the collecting main is positioned at one side of the longitudinal groove.
In this way, forces acting in the transverse direction on the side plates are absorbed in an advantageous manner, rather than being guided into the fastening points of the side plates in the collecting main. The transverse grooves weaken the side plates in this region so that they can easily be influenced by bending forces, so that large forces are converted into a deformation of the side plates in the region of the longitudinal grooves and thus do not act in the longitudinal direction on the fastening points.
In an advantageous manner, the grooves are of sufficient length so that the weakened zone is sufficiently soft to absorb forces. For this purpose, the invention provides that the length of the longitudinal grooves is at least 20 mm.
And the weakening formed by the longitudinal grooves is also to a sufficient extent when determining the width of the longitudinal grooves. In a preferred embodiment, the width of the longitudinal groove is at least 2 mm. It is also provided that the width of the longitudinal groove is advantageously less than 5mm, so that the protective and covering function of the side plate in the region of the longitudinal groove is ensured.
In a preferred embodiment, a longitudinal groove is formed on each side of the side plate. In this way the weakening is distributed to both sides of the side panel.
According to a preferred embodiment of the invention, the lateral plate has at least one transverse groove next to the longitudinal groove. The transverse slots extend perpendicular to the longitudinal direction in the plane of the side plates. The transverse grooves increase the flexibility in the longitudinal direction, so that forces acting in particular in the longitudinal direction can be absorbed by the transverse grooves, so that the fastening points of the side plates are not excessively supported by these forces. In a preferred embodiment, at least one transverse groove is provided, in particular a smaller number of transverse grooves, for example 2 or 3 transverse grooves, can be provided.
In the present invention, the transverse slots may be replaced by each weakened zone of the side panels. The weakening zone can also be formed, for example, by a groove-like indentation in the side panel, which reduces the rigidity of the side panel in particular with respect to the longitudinal extension. Such an indentation may also be combined with one or more grooves in order to form a weakening zone.
According to a first preferred embodiment, the transverse groove is only opened after the side plate has been fixed to the heat sink. In this way it is ensured that the handling of the side plates is facilitated before the side plates are fixed to the cooling body. Here, the transverse slot runs through the entire width of the side plate, in particular dividing the side plate into two half side plates. That is to say two completely separate half-side plates are formed, which exert a smaller force on the fastening point. Furthermore, the connection between the side plates and the cooling body can be made, for example, by brazing, at least in the region of the transverse grooves.
According to a second preferred embodiment, the transverse slot is a die cut extending in the transverse direction. Here, in particular, connecting strips are provided on both sides of the die cut. In order to produce a sufficiently good and dimensionally stable connection over the entire punched-out region, the width of the connecting webs is approximately 5mm each. Here, the connecting strips may preferably project from the plane of the side plates, i.e. rise upwards. This ensures good power absorption in the longitudinal direction while maintaining sufficient form stability of the side panels in the transverse direction during transport. Here, the die cuts may be wavy. Furthermore, the die cut can consist of a U-shaped region with a central slot which extends between the two legs of the U.
According to a further alternative embodiment, two transverse cuts offset from one another in the longitudinal direction can be used as transverse grooves. In this way, it is possible to have at least one interruption of the side panel in the longitudinal direction over the entire width of the side panel, while the side panel is still integral. In this case, it is provided in particular that each transverse cut extends up to an edge extending in the longitudinal direction, while the sum of the lengths of the two transverse cuts is greater than the width of the side panel. That is, an overlapping area of the transverse cuts is formed, and two transverse cuts are present in this area, seen in the length direction of the side panel.
According to a preferred embodiment, the distance of the transverse groove to the connection point between the side plate and the collector tube is greater than 100 mm. In this way, torsion can occur in the region between the transverse groove and the connection point, so that the side plates can be subjected at least in regions to a certain torque and the load on the cooling body or the tube-collecting main connection can be reduced. The distance of the transverse grooves to the connection point between the side plate and the collector tube is preferably greater than 130mm, more preferably greater than 150 mm.
