Strengthened radiator

Abstract

The present invention relates to a strengthened radiator comprising a collector and a water tank, the water tank being provided with a wall (40) and a base (50), a plurality of plates (10) located inside the water tank, wherein each plate (10) comprises a plurality of extensions (20, 20′, 20″, 20′″) having a predetermined format; the base (50) of the wall (40) of the water tank being provided with a plurality of slots (30) having a format corresponding to that of the plurality of extensions (20, 20′, 20″, 20′″), wherein each extension of the plurality of extensions engages each slot of the corresponding plurality of slots.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to a radiator and, more particularly, to a radiator that is strengthened in order to prevent cracks in the collector thereof and failure of the crimping of the teeth of the collector.BACKGROUND OF THE INVENTION[0002]Currently, radiators used in engine cooling systems experience high stresses in the water tanks and in the collector thereof when in a pressure cycle test. This occurs owing to the large dimensions of such water tanks, given the internal oil coolers thereof, causing undesirable cracks in the collector and failure of the crimping of the teeth of the collector.[0003]In order to solve such problems, ribs inside the water tank and / or a plurality of ribs outside said tank are usually added. Such solutions prevent the movement of the wall of the water tank during the pressure cycle test, which causes cracks in the collector and failure of the crimping of the teeth of the collector.[0004]When such a radiator ha...

AI Technical Summary

Benefits of technology

The present invention provides a strengthened radiator that prevents cracks in the collector and increases its lifespan. Additionally, the invention minimizes the movement of the water tank wall during the pressure cycle test, preventing the failure of the crimping of the teeth of the collector.

Problems solved by technology

Currently, radiators used in engine cooling systems experience high stresses in the water tanks and in the collector thereof when in a pressure cycle test.

This occurs owing to the large dimensions of such water tanks, given the internal oil coolers thereof, causing undesirable cracks in the collector and failure of the crimping of the teeth of the collector.

Such solutions prevent the movement of the wall of the water tank during the pressure cycle test, which causes cracks in the collector and failure of the crimping of the teeth of the collector.

When such a radiator has an internal oil cooler, the solution described above of adding a plurality of internal ribs is not possible owing to the absence of space for mounting the oil cooler internally.

In certain special cases, the plurality of internal ribs is insufficient owing to the design of the water tank and the great height of the tank.

However, such solutions are not efficient in terms of preventing cracks in the collector of the radiator or preventing the failure of the crimping of the teeth of the collector (or of the teeth of the profile when the collector does not have teeth).
