1. A detection device, comprising:
a laser ranging sensor; and
a cooling module, which comprises a first protective enclosure and a cooling plate, wherein the first protective enclosure encloses an outside of the laser ranging sensor; the first protective enclosure is provided with an avoidance portion for avoiding a laser light path of the laser ranging sensor; the first protective enclosure has a first opening covered by the cooling plate; an air flow channel is defined inside the cooling plate; surfaces of the cooling plate are provided with air inlet holes and first air outlet holes which are communicated with the air flow channel; and the first air outlet holes are disposed in a first surface of the cooling plate facing the laser ranging sensor to blow air through the first air outlet holes toward the laser ranging sensor to cool the laser ranging sensor,
wherein the air flow channel extends inside the cooling plate in a direction parallel to the first surface of the cooling plate, the air inlet holes extend in a first direction, the first air outlet holes extend in a second direction, and the first direction is perpendicular to the second direction.
