1. Field of the Invention

The present invention relates to a cooler for cooling an electronic device and more particularly, to a modularized cooler.

2. Description of Related Art

FIG. 1 is a rear side view of a fluid cooling type cooler for computer according to the prior art. According to this design, the heat-exchange tubes 10 of the cooler are arranged in a staggered manner that imparts a barrier to the flowing of currents of air caused by the fan 11 , thereby resulting in a high wind resistance between the fan 11 and the heat radiator 1 . The staggered arrangement of the heat-exchange tubes 10 results in a bulky size of the heat radiator 1 .

Referring to FIG. 2 , the heat-exchange tubes 10 of the heat radiator 1 are fixedly mounted inside the radiation fins 12 and arranged into two rows that are spaced from the fan 11 at different distances, thereby defining a hot flow zone 13 and a sub-hot flow zone 14 that cause direct heat conduction at the radiation fins 12 to lower heat dissipation efficiency. Further, because the heat-exchange tubes 10 are fixedly mounted inside the radiation fins 12 , the heat dissipation efficiency of the heat radiator 1 is fixed, and the user cannot change or expand the design.

According to one aspect of the present invention, the modularized cooler comprises the at least two heat radiator modules arranged together. Each heat radiator module comprises a plurality of radiation fins, a plurality of heat-exchange tubes, two locating plates, a plurality of first bends, and a plurality of second bends. The radiation fins are arranged in parallel and spaced from one another in longitudinal direction at a predetermined pitch through which said cooling airflow passing. Each radiation fin has a plurality of through holes extending in longitudinal direction. The heat-exchange tubes are respectively longitudinally mounted inside the through holes of the radiation fins and arranged in parallel. The two locating plates are respectively fastened to the radiation fins at two longitudinally opposite sides. Each locating plate has a plurality of through holes extending in longitudinal direction and respectively coupled to the ends of the heat-exchange tubes. The first bends are connected between every two adjacent heat-exchange tubes at one side of the radiation fins. The second bends are connected between every two adjacent heat-exchange tubes at the longitudinal opposite side of the radiation fins. The first bends and the second bends are arranged in a staggered manner at the two opposite sides of the radiation fins and connected in series to the heat-exchange tubes to form a continuously S-shaped piping, which has an inlet and an outlet.

The modularized cooler further comprises at least one connecting tube connected between the outlet of the continuously S-shaped piping of one of the at least two heat radiator modules and the inlet of the continuously S-shaped piping of another of the at least two heat radiator modules.

Further, the manufacturer can increase the number of the heat radiator modules subject to different demands. The use of the modularized heat radiator modules and their arrangement in parallel eliminate the problem of the prior art design due to direct heat conduction, thereby improving the heat dissipation efficiency of the cooler.

The modularized cooler further comprises at least one fan, for providing a cooling airflow.

Further, the at least two heat radiator modules may be arranged in a stack. The locating plates of the at least two heat radiator modules each have a mounting lug, for fastening together. Further, the mounting lugs of the locating plates of the at least two heat radiator modules each have a mounting hole, threaded with a screw for fastening together.
