An apparatus for purifying a circulating fluid is provided to purify the fluid even without reducing the flow rate, by installing a purifying filter between an outflow tube, which is connected to an outflow hole of a fluid pipe, and an inflow tube, which is connected to an inflow hole of the fluid pipe. A fluid pipe(10) includes an inflow portion(12) and an outflow portion(14). The fluid pipe further includes at least one narrow channel(50) defined by a protrusion formed on an inner circumferential face of the outflow portion. At least one inflow hole(22) is formed in one side of the inflow portion of the fluid pipe so that a fluid takes a roundabout way. An inflow tube(20) has one end connected to the inflow hole. A purifying filter is positioned at the other end of the inflow tube so as to purify the fluid flowing into the inflow tube. An outflow tube(40) has one end connected to the purifying filter and the other end connected to at least one outflow hole(42) formed in the narrow channel of the outflow portion so that the purified fluid flows to the narrow channel of the fluid pipe. |
