Power converting device

Abstract

A power converting device includes a main body having a heat producing part housed therein, a fan case having a cooling fan therein for cooling the heat producing part provided in the main body, and a housing portion in the main body which houses the fan case. The fan case and the housing portion are interconnected so that the fan case is pivotally attached to and detached from the housing portion.

Description

BACKGROUND OF THE INVENTION AND RELATED ART STATEMENT[0001]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.[0002]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...

Benefits of technology

[0007]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.

[0009]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.

[0011]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.

[0012]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.

Problems solved by technology

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.
