The housing frame can be disposed on a first surface of the heat exchanger. The fan unit is configured so that, during operation of the fan unit, a first air flow is produced toward the first surface of the heat exchanger. The fan unit is accommodated in a recess of the housing frame. 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. A measured quantity is recorded by the sensor unit, and the fan unit is driven by the control unit as a function of the recorded measured quantity. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The cooling device as recited in claim 1, wherein the housing frame is detachably mechanically coupled to the heat exchanger. ### Claim 3 (depends on 1) The cooling device as recited in claim 1, wherein the heat exchanger is connected to a heat-radiating apparatus. ### Claim 4 (depends on 1) The cooling device as recited in claim 1, wherein the heat exchanges is connected to a housing of a driving environment sensor. ### Claim 5 (depends on 1) The cooling device as recited in claim 1, wherein the fan unit is accommodated in a recess of the housing frame. ### Claim 6 (depends on 1) The cooling device as recited in claim 1, wherein the first surface of the heat exchanger has a plurality of cooling fins. ### Claim 7 (depends on 6) The cooling device as recited in claim 6, wherein the cooling fins are oriented along the air channel. ### Claim 8 (depends on 1) The cooling device as recited in claim 1, wherein the sensor includes at least one temperature sensor. ### Claim 9 (depends on 8) The cooling device as recited in claim 8, wherein a temperature of the heat exchanger or of a surface to be cooled is recorded as the measured quantity. ### Claim 10 (depends on 1) The cooling device as recited in claim 1, wherein the housing frame has a material having a thermal conductivity of less than 15 W/mK. ### Claim 11 (depends on 1) The cooling device as recited in claim 1, wherein the heat exchanger has a material having a thermal conductivity of more than 50 W/mK. ### Claim 12 (depends on 1) The cooling device as recited in claim 1, wherein: the measured quantity includes at least one of a temperature and a flow velocity, the cooling device is configured to drive the fan unit, as a function of the recorded measured quantity, to generate the first air flow, and the second air flow is generated through the air channel in the case of a movement of the cooling device in a predefined direction. ### Claim 13 (depends on 1) The cooling device as recited in claim 1, wherein the electrically drivable fan unit is accommodated in a recess of a surface of the housing frame, and wherein the controller is accommodated in another recess of the surface of the housing frame. ### Claim 14 (depends on 1) The cooling device as recited in claim 1, wherein the heat exchanger includes a cooling plate having a first surface that faces the housing frame. ### Claim 15 (depends on 1) The cooling device as recited in claim 1, wherein the housing frame includes a material having a particular thermal conductivity, and wherein the heat exchanger includes another material having a higher thermal conductivity. ### Claim 16 (depends on 15) The cooling device as recited in claim 15, wherein the material includes a plastic, and wherein the another material includes a metal, an alloy or a ceramic.
