The invention claimed is: 1. A computer arranged in a housing (1), the housing (1) comprising: a housing cover (3) and a housing floor (4), wherein at least the housing cover (3) comprises a passive cooling member (3a), and the housing cover (3) is arranged to be on top of the housing floor (4) dur
The invention claimed is: 1. A computer arranged in a housing (1), the housing (1) comprising: a housing cover (3) and a housing floor (4), wherein at least the housing cover (3) comprises a passive cooling member (3a), and the housing cover (3) is arranged to be on top of the housing floor (4) during operation of the computer, and an insulator member (5) is arranged between the housing cover (3) and the housing floor (4) to prevent a thermal flow between the housing cover (3) and the housing floor (4), and the computer is arranged to be passively cooled through the passive cooling member (3a), wherein the insulator member (5) divides a volume of the housing (1) in two separate compartments (1a, 1b), a hot compartment ( 1a) and a cold compartment (1b). 2. The computer according to claim 1, wherein the cold compartment is surrounded by the housing floor and the insulating member and the housing floor (4) comprises a passive cooling member ( 4a). 3. The computer according to claim 1, wherein the housing cover (3) and the housing floor (4) consists of metal, in particular aluminum. 4. The computer according to claim 1, wherein the housing cover (3) comprises a top wall (3b) and a sidewall (3c), and/or the housing floor (4) comprises a bottom wall (4b) and a sidewall (4c), and wherein a thickness of at least one of the top wall (3b) and the bottom wall (4b) being at least three times a thickness of the sidewall (3c,4c). 5. The computer according to claim 1, wherein the passive cooling element (3a) comprises outwardly projecting cooling ribs. 6. The computer according to claim 1, wherein the housing cover (3) and the housing floor (4) have a u-shape. 7. The computer according to claim 1, wherein the passive cooling member (3a) has a rough outer surface improving thermal dissipation. 8. The computer according to claim 1, wherein the passive cooling member (3a) has an outer surface with a dark color like black or anthracite. 9. The computer according to claim 1, wherein computer elements with higher power dissipation, such as a power supply or a microprocessor, are arranged in the hot compartment (1a) of the housing (1), and computer elements which need to be operated at lower temperature, such as a hard disk drive or a CD-ROM-drive, are arranged in the cold compartment (1b). 10. The computer according to claim 1, wherein the computer comprises a sensor to measure a temperature in the hot compartment ( 1a), the sensor being connected to a control unit, whereby the control unit controls performance of the computer, in particular the processor's performance, depending on the measured temperature. 11. The computer according to claim 1, wherein the computer comprises a smart card reader (2o) and wherein some of the parts of the smart card reader (2o) are arranged in the hot compartment (1a) and some other parts of the smart card reader are arranged in the cold compartment (1b). 12. The computer according to claim 11, wherein a holder ( 2u) for a smart card (6) is arranged in the cold compartment (1b), and wherein electronics of the smart card reader (2o) is arranged in the hot compartment (1 a). 13. The computer according to claim 1, wherein at least one computer element with a higher power dissipation is arranged to have a thermally conducting connection with the housing cover (3).
