DETAILED DESCRIPTION OF THE INVENTION

[0030] FIGS. 1 - 7 illustrates a measuring apparatus 1 in various embodiments.

[0031] In the embodiments of the measuring apparatus illustrated herein the housing 2 includes a shaped body 3 made from three shaped body parts 4. Additional embodiments include another number of shaped body parts, e.g. more than three or less than three

[0032] FIG. 1 illustrates a measuring apparatus 1 with a housing 2 in an external side view. It is evident from FIG. 1 that the housing 2 includes a shaped body 3 made from three shaped body parts 4. The individual shaped body parts 4 are connected with one another by positive form locking. The mutual engagement of the illustrated form body part 4 generates a positive form locking connection 5 wherein the connected partners cannot separate from each other even when no force is transferred or when the force transfer is interrupted.

[0033] FIGS. 1 - 7 show that the individual components 6 of the entire measuring apparatus 1 are embedded in and enveloped by the shaped body parts 4. It is evident from the embodiments of FIGS. 2 and 4 that the component 6 an be a filter 7, a pump 8 and an evaporator 9. Further embodiments of the component 6 can be an additional pump 10, a sample channel 11 and electronic components 12 as shown in FIGS. 3, 6 and 7.

[0034] It is furthermore evident from FIG. 3. 4 and 6 that the shaped body 3 forms a ventilation channel 13 that includes a fan 14. The pumps 8 and 10 and the evaporator 9 provided with thermal insulation are subject to a heat exchange through the ventilation channel 13 as evident from FIGS. 3 and 6.

[0035] FIGS. 3, 5 and 7 show that the ventilation channel 13 extends at more than one level, so that the component 6 that are arranged over more than one level are cool able.

[0036] In order to keep the desired operating temperaturestable, a temperature sensor 15 is arranged in the ventilation channel 13. The components 6 of the measuring apparatus 1 form undercuts 16 with respect to the shaped body 3 which keep with shaped body 3 in one piece in the assembled condition.

[0037] FIG. 2 shows that the shaped body 3 includes a recess 17 configured to receive the component 6 configured as the evaporator 9. Thus, the evaporator 9 can be supported form stable in the shaped body 3.

[0038] In order to assure reliable and firm support of the individual components 6, a compression rib 18 is formed at or in the shaped body 3 protruding outward from a side wall of the shaped body into the at least one recess 17.

[0039] FIGS. 1 - 7 show a measuring apparatus 1 with a housing 2 and a shaped body 3 made from a foam material wherein at least one additional housing 19 is arranged about the shaped body 3. The at least one additional housing 19 formed from metal or a synthetic material can be configured with at least one ventilation slot 20 at a location where the at least one ventilation channel 13 exits.

[0040] According to an advantageous embodiment of the invention a measuring apparatus with at least one housing part 2 is provided wherein the at least one housing part 2 includes a shaped body 3 made from a foam material.
