Benefits of technology

The present invention provides a plastic component that is simple and inexpensive to produce, while also being rigid enough. The plastic component has at least one pocket or multiple pockets that protrude from the wall. These pockets have a second and third wall, with the second wall angled at an angle greater than 45° and the third wall angled at an angle less than 45°. This design creates reinforcing elements in the first wall, making it stronger and more rigid. The third wall can also be parallel to the first wall, creating a reinforcing effect between the first and third walls. Overall, this design provides a plastic component that is both cost-effective and structurally sound.

Problems solved by technology

As compared to the embodiment of the wall of the component, the embodiment of reinforcing ribs requires additional material that must be used in order to increase the rigidity, but this increases costs.
Such components with correspondingly embodied surfaces, however, do not exhibit the required rigidity particularly relative to a maximum internal pressure that occurs.

Embodiment Construction

[0040]FIG. 1 shows a plastic component 1, which is embodied in the form of an evaporator housing and constitutes an air duct.

[0041]The plastic component 1 has two first walls 2 that are embodied as planar in this exemplary embodiment. The two first walls are oriented at an angle of approximately 90° to each other and are connected to each other. Each first wall 2 is provided with a plurality of pockets 3. Alternatively, it is also possible to provide only one pocket 3.

[0042]The pocket 3 is depicted in greater detail in the schematic cross-sectional view A.

[0043]In this case, the pocket 3 is composed of a bulge that protrudes out from the plane 4 of the wall 2. The pocket 3 here has at least one second wall 5 and one third wall 6. The second wall 5 is oriented at an angle α relative to the plane 4 of the first wall 2. The angle α here is preferably greater than 45°, in particular greater than 90°. The third wall 6 is oriented at angle β relative to the plane 4 of the first wall 2. Th...

Abstract

A plastic component with at least one first wall in which a pocket or a plurality of pockets is provided. A pocket can constitute a bulge that protrudes out from the plane of the wall. The pocket has at least one second wall and one third wall. The second wall is oriented at an angle relative to the plane of the first wall and the angle is greater than 45° and the third wall is oriented at an angle relative to the plane of the first wall that is less than 45°.

Description

[0001]This nonprovisional application claims priority under 35 U.S.C. §119(a) to German Patent Application No. 10 2014 209 323.6, which was filed in Germany on May 16, 2014, and which is herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a plastic component, in particular a plastic component of a heat exchanger or an air conditioning system, in particular of a motor vehicle.[0004]2. Description of the Background Art[0005]Plastic components, particularly for heat exchangers or air conditioning systems, have at least one wall that is generally embodied as relatively thin and for reinforcing purposes, is provided with reinforcing ribs on the outside or inside. There are thus known collector boxes of heat exchangers with reinforcing ribs that are usually mounted on the outside. There are also known air conditioning system housings that have reinforcing ribs on the outside in order to improve the rigidity of e...
