The cogeneration system according to claim 1, wherein the drive source is an engine or a fuel cell. 3. The cogeneration system according to claim 1, wherein the drive source includes an air suction tube adapted to suck air present around the chassis into the drive source. 4. The cogeneration system according to claim 1, further comprising: a muffler mounted to an exhaust tube adapted to discharge exhaust gas from the drive source. 5. The cogeneration system according to claim 3, further comprising: a muffler casing mounted to the chassis, and adapted to protect the muffler and to shield noise of the muffler. 6. The cogeneration system according to claim 5, wherein the muffler casing comprises: a first muffler casing mounted on a top of the chassis such that the first muffler casing surrounds the muffler, and provides a passage, through which air absorbing heat from the engine room passes; and a second muffler casing arranged at one side of the first muffler casing to provide a passage, through which the air emerging from the first muffler casing passes to be outwardly discharged. 7. The cogeneration system according to claim 1, wherein the chassis includes an engine room defined in the chassis to receive the generator, the drive source, and the waste heat recoverer. 8. The cogeneration system according to claim 7, wherein the waster heat supplier is arranged in the engine room. 9. The cogeneration system according to claim 7, further comprising: a ventilation device mounted to the chassis to radiate heat from the engine room. 10. The cogeneration system according to claim 9, wherein the ventilation device comprises: a ventilation casing which communicates with the engine room of the chassis, and includes a grill mounted to one side of the ventilation casing; and a ventilation fan connected to a motor arranged in the ventilation casing to blow outdoor air to the engine room. 11. The cogeneration system according to claim 7, wherein the radiator is arranged on a top of the chassis to discharge heat upwardly from the chassis. 12. The cogeneration system according to claim 11, wherein the radiator includes: a radiating fan arranged to blow outdoor air to the radiating heat exchanger; and a grill arranged over the radiating heat exchanger and the radiating fan. 13. The cogeneration system according to claim 7, further comprising: a partition wall which isolates the radiator and the engine room from each other. 14. A cogeneration system comprising: a generator which generates electricity; a drive source which operates to drive the generator, and generates waste heat during the operation of the drive source; a waste heat recoverer which recovers the waste heat of the drive source; a waste heat supplier which transfers the waste heat recovered by the waste heat recoverer to a heat consumer; a chassis which includes an engine room defined in the chassis to receive the generator, the drive source, the waste heat recoverer, and the waste heat supplier; a radiator mounted to the chassis to radiate the waste heat recovered by the waste heat recoverer; a muffler mounted to an exhaust tube adapted to discharge exhaust gas from the drive source; a muffler casing mounted to the chassis, and adapted to protect the muffler and to shield noise of the muffler; and a ventilation device mounted to the chassis to suck air present around the chassis into the engine room, and to outwardly discharge the air from the engine room via the muffler casing for heat radiation of the engine room. 15.
