DETAILED DESCRIPTION OF PREFERRED BEST MOLDS
Referring to FIGS. 2 and 3, the first embodiment of the present invention provides a water block 100 that comprises a first casing 1, a second casing 2, and a plurality of fins 5.
The first casing 1 has a solder reserve area 3 formed on an outer edge thereof. When the first casing 1 joints with the second casing 2, the solder reserve area 3 becomes a gap formed at an inner side of a joint between the first casing 1 and the second casing 2. The first casing 1 joints with the second casing 2 to form a channel space 4, a passage hole 42, and a passage hole 43. The two passage holes 42, 43 respectively joint with two guiding tubes (not shown). The fins 5 are attached onto the first casing 1 so as to divide the channel space 4 into a plurality of flow channels 41. In other embodiment, the fins 5 are disposed on the second casing 2, or on the first casing 1 and the second casing 2. Hence, the fins can be integratedly formed on the first casing 1 and/or the second casing 2.
Referring to FIGS. 4 and 5, the second embodiment of the present invention provides a water block 200 that comprises a first casing 1b and a second casing 2b. The water block 200 is H-shaped, and the first casing 1b and the second casing 2b joint together to form a channel space 4b and four passage holes 4c. The first casing 1b has a U-shaped groove formed on an outside edge thereof. An outside edge of the second casing 2b is received in the U-shaped groove in order to joint the first casing 1b and the second casing 2b together. A solder reserve area 3b, which is also a gap, is formed at an outer side of a joint between the first casing 1b and the second casing 2b. Fins (not shown) can be disposed on the first casing 1b and/or the second casing 2b in order to divide the channel space 4b into a plurality of flow channels (not shown).
Referring to FIGS. 6 and 7, the third embodiment of the present invention provides a water block 300 that comprises a first casing 1c, a second casing 2c with a square post shape, and a third casing 1d. The first casing 1c, the second casing 2c, and the third casing 1d joint together to form a channel space 4d. The first casing 1c has a passage hole 4e formed thereon and an annular concave groove 3c formed on an inside thereof. The third casing 1d has a passage hole 4e formed thereon and an annular concave groove 3c formed on an inside thereof. The annular concave groove 3c has a width larger than that of a thickness of a sidewall of the second casing 2c. Two sides of the second casing 2c are received into the two annular concave grooves 3c of the first casing 1c and the third casing 1d in order to joint the first casing 1c and the third casing 1d on the two sides of the second casing 2c. Hence, solder reserve areas 3d can be formed at two outer sides and two inner sides of two joints between the first casing 1c and the second casing 2c and between the second casing 2c and the third casing 1d. In another embodiment, referring to FIG. 8, the thickness of the second casing 2c is smaller, so that the solder reserve areas 3e are formed at the two outer sides of two joints between the first casing 1c and the second casing 2c and between the second casing 2c and the third casing 1d. According to the same principle, referring to FIG. 9, the thickness of the second casing 2c is larger, so that the solder reserve areas 3f are formed at the two inner sides of two joints between the first casing 1c and the second casing 2c and between the second casing 2c and the third casing 1d. The second casing 2c further includes a plurality of fins (not shown) in order to divide the channel space 4d into a plurality of flow channels (not shown).
The above-mentioned passage holes can be design to fit guiding tubes with any shapes. Moreover, according to the above-mentioned disclosures, the solder reserve areas can be disposed between any two casings.
Referring to FIG. 10, the present invention provides a method of manufacturing a water block. The method of steps comprises: providing a first casing that has a solder reserve area formed on an outer edge thereof (S110); coating a solder paste on the solder reserve area, the solder past being composed of tin solder and flux, and the flux occupying about 5˜15% of the content of the tin solder (in the range of 5˜15%, the rate of bubbles is 10.5%) (S120); jointing a second casing with the first casing via the solder past to form a channel space (the solder past is filled into the solder reserve area that is a gap between the first casing and the second casing) (S130); separating the flux from the tin solder and removing bubbles of the tin solder from the solder reserve area at a soft soldering temperature of between 200˜400° C. (S140); and waiting for the water block to be cooled (S150).
Moreover, fins can be disposed on the first casing and/or the second casing in order to divide the channel space into a plurality of flow channels.
Although the present invention has been described with reference to the preferred best molds thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
