What is claimed is: 1. An electronic apparatus, installing a semiconductor element generating heat within an inside of a housing, thereby necessitating cooling for maintaining a normal operation thereof, and including a cooling system within the inside of said housing or in a portion thereof, said cooling system comprising: a cooling jacket being thermally connected to the semiconductor element, for transmitting heat generated therefrom into a liquid coolant flowing inside thereof; a radiator for radiating the heat transmitted into the liquid coolant in said cooling jacket into an outside of the apparatus; and a circulation pump for circulating said liquid coolant within a loop, including said cooling jacket and said radiator therein, wherein: said circulation pump is provided in a plural number thereof, and further circulation pumps are provided with a bypass channel and a check valve, which has means for detecting malfunction of the circulation pumps. 2. The electronic apparatus having the liquid cooling system therein, as described in the claim 1, wherein two (2) sets of said circulation pumps are connected in series, and said liquid coolant circulation maintaining means comprises flow passages, being connected to said two (2) sets of circulation pumps, respectively, and check valves, each being attached to a portion of each of the flow passages. 3. The electronic apparatus having the liquid cooling system therein, as described in the claim 1, wherein two (2) sets of said circulation pumps are connected in parallel, and said liquid coolant circulation maintaining means comprises a three-way valve connected to said two (2) sets of circulation pumps. 4. The electronic apparatus having the liquid cooling system therein, as described in the claim 1, wherein said liquid coolant circulation maintaining means further comprises a means for increasing rotation velocity of said other circulation pumps when the one of said plural number of circulation pumps stop the function thereof. 5. The electronic apparatus having the liquid cooling system therein, as described in the claim 4, wherein said rotation velocity increase means for the circulation pumps is built up with using a portion of said semiconductor element. 6. The electronic apparatus having the liquid cooling system therein, as described in the claim 4, wherein said liquid coolant circulation maintaining means further comprises an alarm means for warning of stoppage of said function when the one of said plural number of circulation pumps stop the function thereof. 7. The electronic apparatus having the liquid cooling system therein, as described in the claim 1, wherein said liquid cooling system further comprises a tank being able to supply the liquid coolant therefrom, always in spite of dispositional direction thereof. 8. A cooling system, for cooling a semiconductor element generating heat therefrom, comprising: a cooling jacket being thermally connected to a semiconductor element, for transmitting heat generated therefrom into a liquid coolant flowing inside thereof; a radiator for radiating the heat transmitted into the liquid coolant in said cooling jacket into an outside of the apparatus; and a circulation pump for circulating said liquid coolant within a loop, including said cooling jacket and said radiator therein, wherein: said circulation pump is provided in a plural number thereof, and further circulation pumps are provided with a bypass channel and a check valve, which has means for detecting malfunction of the circulation pumps. 9. A cooling system, for cooling a semiconductor element generating heat therefrom, comprising: a cooling jacket being thermally connected to a semiconductor element, for transmitting heat generated therefrom into a liquid coolant flowing inside thereof; a radiator for radiating the heat transmitted into the liquid coolant in said cooling jacket into an outside of the apparatus; and a circulation pump for circulating said liquid coolant within a loop, including said cooling jacket and said radiator therein, and further comprising: a coolant tank, being divided in an inside thereof into a plural number of spaces, wherein each space includes at least one L-shaped wall member for trapping air inside the space in an upstream side of said circulation pump.
