1. A cooling device for a driving environment sensor of a motor vehicle, comprising:
a housing frame;
a heat exchanger;
an electrically drivable fan unit;
a controller; and
a sensor;
wherein the fan unit is configured so that, during operation of the fan unit, a first air flow is generated toward a first surface of the heat exchanger,
wherein the housing frame has at least one air channel having an air inlet opening and an air outlet opening, the air channel being formed parallel to the first surface of the heat exchanger, allowing a second air flow to pass through the air channel along the first surface,
wherein at least one measured quantity is recorded,
wherein the controller is configured to drive the fan unit as a function of the at least one recorded measured quantity, and
wherein the housing frame is arranged on the heat exchanger and partially projects laterally beyond the heat exchanger, and wherein a lateral length of the housing frame is greater than a height or depth of the housing frame.
