1. A cooling device for a front end of a motor vehicle, comprising:
at least one heat exchanger which has a plurality of coolant channels around which air can flow,
an apparatus which is connected upstream from the heat exchanger and which has a support frame having a through-flow opening for air to flow to the heat exchanger, and
at least one closing element that is movably mounted on the support frame and that is intended to open, partially open, and close the through-flow opening,
wherein the closing element is configured as a roller blind which, in a first end position, extends over the support frame so as to close the through-flow opening, and which, in a second, rolled-up end position, completely opens the through-flow opening,
wherein the support frame has a grid supporting structure that is located in the through-flow opening and has intersecting struts for the roller blind,
wherein the grid supporting structure has at least one plate-shaped support element on the side of the grid supporting structure comprising a planar contact surface and facing away from the roller blind in order to establish contact with the heat exchanger.
