Embodiment Construction

[0022] Embodiments of the present invention will be described below based on the drawings.

[0023] figure 1 It is a perspective view showing the appearance of an inverter device as a power conversion device. In the figure, 1 is an inverter device as a power conversion device, and has a main body 2 incorporating switching elements such as IGBTs as heat-generating components. The main body 2 has a structure in which front and rear casing halves 2A and 2B are connected, and air intake holes 3 are formed in both casing halves 2A and 2B.

[0024] An operation display unit 4 for performing various operations, settings, and displays is provided on the casing half body 2A on the front side. In addition, in the casing half body 2B on the rear side, a fan storage portion 5 is formed on the uppermost portion over the entire upper surface, and a cooling fan 6 is detachably attached to the fan storage portion 5 through a hinge mechanism 8 . The fan housing 7.

Abstract

The invention provides a power converting device having simple structure and capable of making the attachement and the disattachment of a fan case easier, relative to a main body, without needing additional fixing component, wherein the fan case has a cooling fan. A power converting device includes a main body 2 having a heat producing part housed therein, a fan case 7 having a cooling fan 6 therein for cooling the heat producing part arranged in the main body, and a housing portion 5 in the main body 2 which houses the fan case 7. The fan case 7 and the housing portion 5 are interconnected so that the fan case is pivotally attached to and detached from the housing portion.

Description

technical field [0001] The present invention relates to a power conversion device in which a cooling fan is attached to a main body housing heat-generating components, and particularly relates to a power conversion device in which the cooling fan can be easily replaced. Background technique [0002] As such a power conversion device, for example, an inverter device is known, which has, for example, a heat-generating component housed inside a main body and a cooling fan for cooling. The inverter device includes: a fan unit case that integrally houses the cooling fan; A storage space formed outside the top surface of the main body of the inverter unit to accommodate the fan unit case by sliding; The cooling fan is mounted and detached by sliding, and the cooling fan is fixed to the fan unit case by claws without screws (for example, refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2007-325383 [0004] However, in the conve...
