Description

  The present invention relates to a cabinet for housing an electronic device equipped with a heat-generating electronic component, such as a VDSL (very high bit rate digital subscriber line) device.

  In recent years, digital devices such as personal computers have become widespread, and are rapidly spreading in general homes as well as for business use. In connection with this, in order to use digital devices provided in each room in the office and home more conveniently, it is required to construct a network by interconnecting them. In addition, information transmitted / received between interconnected devices is large-capacity sound, images, etc., and in order to transmit these, silica-based optical fibers, plastic optical fibers, etc., which are transmission media capable of high-speed transmission The optical fiber cable is used.

  When using optical fiber cables in apartment buildings or complex buildings, etc., the optical fiber cables are wired to common areas such as in apartment buildings and complex buildings, and the optical line terminator ONU (Optical Network Unit) and collective line terminator / A number of systems are used in which a communication network is configured by connecting each room with a LAN cable via a VDSL aggregation device (hereinafter referred to as a VDSL device).

  An ONU is a device for connecting a terminal device such as a personal computer to a network in an optical fiber subscriber communication network, and converts an optical signal flowing through the optical fiber into an electrical signal or an electrical signal sent to the optical fiber. To convert light into a light signal.

  Conventionally, in the case of an apartment house or a complex building, the VDSL device is housed in a cabinet together with the optical line termination device ONU, and is arranged in a common part such as an apartment house or a complex building. In order to generate heat when the VDSL device operates, the cabinet needs a cooling device such as ventilation.

  In addition, there has been proposed an electronic equipment cabinet that minimizes adverse effects of electronic equipment due to heat from the outside caused by direct sunlight and heat generated from the inside (see Patent Document 1).

  In this case, at least one of the front, back, left and right sides of the cabinet body in which the electronic device M is disposed is at least one side and the upper part of the inner panel and the outer panel functioning as a sunshade. The panel forms a ventilation duct, and has a structure including an exhaust fan for flowing cooling air into the ventilation duct and a radiator for exchanging heat with the cooling air flowing in the ventilation duct. The heat from the inside is blocked by the outer panel, while the heat from the inside is cooled by heat exchange at the time of contact with the radiator.
