Abstract
Description
- The present invention relates to a power converting device which encloses a cooling fan in a main body housing of a heat producing device, and in particular, relates to a power converting device in which it is possible to easily replace the cooling fan.
- As this kind of power converting device, there is known an inverter with, for example, a heat producing device housed inside a main body, and a cooling fan for cooling. The fan includes a fan unit case which houses the cooling fan. A housing space is formed in an external side of an upper surface of the inverter device main body, and such that the fan unit case can be slid into and housed therein. A fan cover which fixes the fan unit case in place, is fixed to the fan unit case without screwing by a pawl, and in such a way that the fan unit case can be inserted and removed from the fan unit case housing space by sliding it backwards and forwards (for example, refer to JP-A-2007-325383).
- However, with the heretofore known example described in JP-A-2007-325383, although it slidably holds the fan unit case detachably in the main body, there is an unresolved problem in that, a separate fan retaining cover is necessary along with a guide member to prevent the cover from falling vertically down. This renders the structure undesirably complex.
- The invention has been contrived bearing in mind the unresolved problem of the heretofore known example, and is directed to providing a power converting device wherein it is possible, with a simple configuration, to easily attach and detach a fan case, in which a cooling fan is mounted, to and from a main body, without the need of a separate fixing member.
- Further objects and advantages of the invention will be apparent from the following description of the invention.
- In order to achieve the heretofore described object, a power converting device according to one aspect of the invention, includes a heat producing part housed inside a main body, and a cooling fan which cools the heat producing part provided in the main body. A housing portion which houses a fan case, in which the cooling fan is disposed, is formed in the main body. The fan case and the housing portion are provided with connection features which allow it to be mounted so as to be pivotal with respect to and therefore readily attachable to, and detachable from the housing portion.
- According to this configuration, as the fan case in which the cooling fan is disposed, is, in one embodiment, hingedly mounted so as to be attachable to, and detachable from the housing portion of the main body, it is possible, with a simple configuration, to easily carry out attachment and detachment of the fan case to and from the housing portion of the main body.
- Also, with the power converting device according to this aspect of the invention, it is preferable that a hinge portion is formed on one side surface of the fan case, a flexible lock portion or feature is formed on another side surface opposing the hinge portion, hook portions or features, which pivotally hold the hinge portion, are formed on one side surface of the housing portion, and a fitting portion in which the lock portion fits is formed on a side surface opposing the hook portions.
- With this configuration, is possible to achieve a locked condition by inserting the hinge portion of the fan case in the hock portion of the housing portion and, in this condition, fitting the lock portion in the fitting portion. This, therefore, makes it possible to reliably secure the fan case in the main body without providing a separate fixing cover, or the like.
- Also, with the power converting device according to another embodiment of the invention, it is preferable that an engagement portion has a supporting member including a projecting plate portion parallel to the top surface of the fan case; a vertical plate portion extending upward from a free end of the projecting plate portion, and rib portions sandwiching the supporting member, formed on one side surface of the fan case, and a flexible lock portion formed on another side surface opposing the engagement portion. The engagement portion is engaged and held on one side surface of the housing portion, and a fitting portion in which the lock portion fits, is formed on a side surface opposite that side surface.
- With this embodiment, it is possible to achieve a locked condition by forming the engagement portion of the supporting member and rib portions, engaging and holding the engagement portion on a side surface of the main body, and fitting the lock portion in the fitting portion formed in the housing portion of the main body. This renders it possible to reliably fix the fan case in the main body without providing a separate fixing cover, or the like.
- According to these embodiments of the invention, as the fan case in which the cooling fan is disposed, is pivotal during attachment to, and detachment from the housing portion of the main body housing heat producing part of power converting device, an advantage is obtained in that, as well as it being possible to simplify the overall configuration, with no need for a separate fixing cover, or the like, it is possible to easily carry out attachment and detachment of the fan case.

-
FIG. 1 is an external perspective view showing an inverter device acting as a power converting device. In this drawing,numeral 1 is the inverter device acting as the power converting device, and includes amain body 2 in which is housed a switching element, such as an IGBT, as a heat producing member. Themain body 2 has a configuration wherein front and rear case half-bodies air intake vents 3 are formed in both of the case half-bodies 2Aad 2B. - An
operation display module 4, with which various kinds of operation, settings, and data are displayed, is provided in the front case half-body 2A. Also, afan housing portion 5 is formed over the whole of the top surface, in an uppermost portion, of the rear case half-body 2B. Afan case 7, in which is mounted acooling fan 6, is attachably and detachably disposed in thefan housing portion 5 with ahinge mechanism 8. - The
fan housing portion 5 is configured of left andright side walls body 2B, and a depressed portion 2 c formed between them.Hook portions 12, which formhinge receiving grooves 11 extending in a front-back direction and form thehinge mechanism 8, are disposed in the front-back direction, at a predetermined interval, on theleft side wall 2 a, as shown inFIG. 2 . Also, afitting portion 13, in which is fitted a lock portion of thefan case 7, to be described hereafter, is formed in theright side wall 2 b, as shown inFIGS. 3 and 4 , and alock release opening 14 is formed passing from thefitting portion 13 through to a right side surface side. - Meanwhile, as shown in
FIGS. 5 and 6 , thefan case 7 is formed of arectangular frame portion 21, and a topsurface plate portion 22 which closes off the top surface of therectangular frame portion 21. The rectangular frame portion has an open bottom surface. A supportingplate portion 23 with an L-shaped cross-section, has aprojecting plate portion 23 a projecting leftward and avertical plate portion 23 b extending upward from a free end of the projectingplate portion 23 a, is formed on a leftside surface plate 21 a of therectangular frame portion 21. Ahinge shaft 24, which engages with thehinge receiving grooves 11 of thehook portions 12 configuring thehinge mechanism 8 formed in thefan housing portion 5 of themain body 2, is formed on the top end of thevertical plate portion 23 b of the supportingplate portion 23. Also, aflexible lock portion 25 with a U-shaped cross-section, whose top end is open, is formed on a rightside surface plate 21 b of therectangular frame portion 21. Furthermore, a plurality ofrib portions 26, which maintain strength, are formed parallel to each other extending in a vertical direction on the back surface side of thelock portion 25, as shown inFIG. 6 . -
Vent holes 27 according to the shape of thecooling fan 6 are formed in the topsurface plate portion 22, as shown inFIG. 5 . Thecooling fan 6 is mounted on the interior side of thevent holes 27, as shown inFIG. 4 . - As shown in
FIG. 4 , by fitting thelock portion 25 into thefitting portion 13 of thehousing portion 5 and pushing it in, and then by causing thefan case 7 to pivot, with thehinge shaft 24 as a center of rotation, in a condition in which itshinge shaft 24 is engaged inside thehinge receiving grooves 11 of thehook portions 12 formed in thehousing portion 5, thelock portion 25 is fitted into thefitting portion 13 while bending, and secures thefan case 7 in position. - Next, a description will be given of an operation of the heretofore described embodiment.
- Under normal conditions, the
fan case 7 in which thecooling fan 6 is mounted is mounted in thefan housing portion 5 formed in the upper portion of the case half-body 2B configuring themain body 2, in a state in which thehinge shaft 24 is engaged in thehinge receiving grooves 11 of thehook portions 12 of thehousing portion 5, and thelock portion 25 is fitted into thefitting portion 13 of thehousing portion 5, as shown inFIGS. 1 and 3 . An IGBT, or the like, which is an internal heat producing part, is cooled by thecooling fan 6 when driven to rotate. - In the event of replacing the
cooling fan 6 in this condition, a supply of power to an inverter circuit configured of the internal IGBT, or the like, is stopped, theU-shaped lock portion 25 is depressed by inserting the tip of a tool such as a screwdriver into the lock release opening 14, causing the fitting of thelock portion 25 in thefitting portion 13 to be disengaged, and in this condition, thefan case 7 is pivoted upward centered on thehinge shaft 24, as shown inFIG. 4 , by gripping, for example, the side surfaces thereof. - In this state, by disengaging the
hinge shaft 24 from thehinge receiving grooves 11 of thehook portions 12, it is possible to remove thefan case 7 from thehousing portion 5. Then, thecooling fan 6 exposed from the rear surface side of the removedfan case 7 is disengaged from thefan case 7 by removing a locking screw, or removing a mounting claw, after which, anew cooling fan 6 is mounted in thefan case 7. - Subsequently, by pivotally mounting the
fan case 7 in thehousing portion 5 by engaging thehinge shaft 24 in thehinge receiving grooves 11 formed in thehook portions 12 of thehousing portion 5 and, in this condition, causing thefan case 7 to pivot downward centered on thehinge shaft 24, fitting thelock portion 25 into thefitting portion 13, and pushing it in, it is possible to mount and secure thefan case 7 in thehousing portion 5, as shown inFIG. 3 . - In this way, in the heretofore described embodiment, in the condition in which the
fan case 7 is pivotally held in thehousing portion 5 of the case half-body 23 with thehinge mechanism 8, it is possible to easily mount thefan case 7 in thehousing portion 5 by causing thefan case 7 to turn to the bottom portion side of thehousing portion 5, fitting thelock portion 25 into thefitting portion 13. - Moreover, in this case, it is possible to hold the
fan case 7 without it coming out of thehousing portion 5 simply by fitting thelock portion 25 provided in thefan case 7 in thefitting portion 13 of thehousing portion 5. Thus, it is possible to simplify the configuration in comparison with the case in which the fan case is slidably held, and fixed with a fan cover, as in the previously described heretofore known example, and it is also possible to improve operability when mounting. - Also, in the case too of removing the
fan case 7 from thehousing portion 5 in order to replace thecooling fan 6, it is possible to cause thefan case 7 to turn upward simply by inserting the tip of a tool such as a screwdriver from the lock release opening 14, bending the U-shapedlock portion 25, and releasing its fitting in thefitting portion 13. This makes it is possible to easily remove thefan case 7 from thehousing portion 5 by disengaging thehinge shaft 24 from thehinge receiving grooves 11 of thehook portions 12 in the condition ofFIG. 4 . - In the heretofore described embodiment, a description has been given of a case of pivotally mounting the
fan case 7 in which thecooling fan 6 is mounted in the housing portion, via thehinge mechanism 8. However, the instant invention is not limited to this, and it is possible to omit thehinge shaft 24 formed on the to end of thevertical plate portion 23 b of the supportingmember 23, by forming reinforcingrib portions 31 in positions in front of and behind the supportingmember 23, and using them as an engagement portion, as shown inFIG. 7 . - By omitting the
hook portions 12 of thehousing portion 5 and, in a condition in which thefan case 7 is tilted left side up, by moving thevertical plate portion 23 b of the supportingmember 23 downward while bringing it into contact with theleft side wall 2 a forming thehousing portion 5, causing thelock portion 25 side to turn to the bottom surface side of thehousing portion 5, and fitting thelock portion 25 in thefitting portion 13, when the bottom surface of the supportingmember 23 side of thefan case 7 comes into contact with the bottom surface of thehousing portion 5, as shown inFIG. 8 , it is possible to keep thefan case 7 secured in thehousing portion 5, against upward movement, by biasing thevertical plate portion 23 b of the supportingmember 23 against theleft side wall 2 a using the springiness of thelock portion 25. - Then, in the case of removing the
fan case 7 from thehousing portion 5, by inserting the tip of a tool such as a screwdriver in thelock release opening 14 and bending thelock portion 25, in the same way as in the previously described embodiment, and, in a condition in which it is separated from thefitting portion 13, gripping thelock portion 25 sides and lifting it up, it is possible, by causing thefan case 7 to pivot with thevertical plate portion 23 b of the supportingmember 23 still engaged with theleft side wall 2 a, and moving thefan case 7 upward, as it is, inFIG. 8 , to easily remove thefan case 7 from thehousing portion 5. - In this instance, by forming a comparatively low projection on the left side wall of the
housing portion 5 in such a way as to come into contact from above with the too end of thevertical plate portion 23 b of the supportingmember 23 in toe condition in which thefan case 7 is housed, in order to reliably prevent escape of thefan case 7 from thehousing portion 5 to the exterior, it is possible, in the event that thefan case 7 tends to move upward, to reliably prevent the upward movement by the top end of thevertical plate portion 23 b engaging with the projection. - In the heretofore described embodiments, a description has been given of a case in which the
main body 2 of theinverter device 1 is configured of the case half-bodies housing portion 5 not being limited to the top end portion of themain body 2, it may be formed in a side surface other than the top end portion. - Although not shown, the fan is suitably adapted to be connected to a source of electrical power. Also, in the heretofore described embodiments, a description has been given of a case in which an inverter device is applied as the power converting device but, not being limited to this, the invention can also be applied to another type device, such as an uninterruptible power supply or the like.
