DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In describing a preferred embodiment of medical measuring apparatus in accordance with the invention illustrated in the drawings, specific terminologies and numerals will be resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms and numerals so selected, and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.
Referring to FIGS. 2 to 6 for a structure for fixing a fan with a computer casing in accordance with the present invention, the device has a casing 10, and the casing of this embodiment is a tower desktop computer, and the front side of the casing 10 has a front panel 11, and the casing 10 contains a motherboard 20, and the motherboard 20 installs electronic components such as a CPU and an interface card, etc. The casing 10 also has an opening 12 disposed on a corresponding side facing the motherboard 20 and with a size equal to half of the motherboard 20, and the casing 10 has a locking hole 13 disposed at each distal edge of the opening 12, and the linear distance between two adjacent locking holes 13 is equal to 170±5 mm, and the opening 12 installs a heat dissipating fan 30 which is a large fan in this embodiment, and the periphery of the fan 30 has a protruding ear 31 protruded outward, and the protruding ears 31 separately have a plurality of locking holes 311, and the locking holes 311 correspond to the locking holes 13 at the periphery of the opening 12, such that the locking member 32 (which is a screw rod in this embodiment) can be passed through the locking hole 311 and secured into the locking hole 13, and fixed onto the casing 10. Such arrangement not only successfully installs the fan 30 onto a surface of the casing 10, but also results in no increase of area of the casing 10. Since the interval of the locking holes 13 complies with the locking holes 311 of the fan 30, it is not necessary to drill holes for the installation. During its use, the heat produced by all electronic components on the motherboard 20 can be discharged by the fan 30. The invention definitely can eliminate the heat in the casing 10 by discharging the heat out from the casing 10 or drawing cold air from the outside into the casing 10.
In FIGS. 4 to 7, the surrounding of the fan 30 has through holes 33, such that if the casing 10 is attached to a wall or a table leg, then the flow of the outside air or discharged air will not be blocked, but air can be entered into or discharged from the through holes 33 (as shown in FIG. 7).
Referring to FIG. 5, the fan 30 can be fixed to a fan base 34, and the fan base 34 can be integrated or locked with the fan 30, and each distal edge of the fan base 34 has a locking hole 341 corresponding to a locking hole 13 (not shown in the figure) with an equal distance apart, such that a locking member 32 (which is a screw rod) can be passed through the locking hole 341 and secured into the locking hole 13 and fixed onto the casing 10. Such arrangement not only successfully installs the fan 30 onto a surface of the casing 10, but also needs not to increase the area of the casing 10. Since the interval of the locking holes 13 complies with the locking holes 311 of the fan 30, therefore it is not necessary to drill any hole for the installation.
Referring to FIG. 6, the fan base 34 can install a plurality of small fans 30 with different sizes, and this embodiment adopts two small fans.
Referring to FIGS. 4 to 6, the heat dissipating fan 30 of the invention can install a filter 40 for filtering dusts or ashes in the air.
In summation of the description above, the design of the present invention can enhance the heat dissipating efficiency of the computer and its special effect can overcome the shortcomings of the prior art. The structural and technical characteristics of the invention are disclosed in the foregoing embodiments, and the invention complies with the requirements of patent applications, and is duly submitted to file a patent application.
While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
