Patent ID: 8705012

Claim:
Device for optically scanning and measuring an environment, said device being designed as a laser scanner comprising: a light emitter, which emits an emission light beam, a light receiver which receives a reception light beam which is a portion of the emission light beam reflected from an object in the environment, and a control and evaluation unit connected to the light receiver which, for a multitude of measuring points, determines a distance to the object, wherein the laser scanner is provided with a carrying, a shell serving as an outer housing, and a cooling device, said cooling device further comprising an air inlet, a space between the carrying structure and the shell, said space opening to the environment by means of the air inlet and otherwise being sealed with respect to an interior of the carrying structure and to the shell, a suction duct opening to the space between the carrying structure and the shell, an outlet duct, a fan having a fan housing connected to the suction duct and to the outlet duct in a sealed manner, an air outlet at which the outlet duct terminates sealed with respect to the space, wherein the fan sucks in air through the air inlet, pulls the air through the space and the suction duct, and blows the air out of the laser scanner through the outlet duct and the air outlet.
