Description

  The present invention relates to a device mounting structure for a ventilation fan.

  The cabinet for storing electrical and electronic equipment is usually provided with a plurality of ventilation fans in order to suppress the temperature rise inside the cabinet due to heat generated by the internal equipment and to prevent condensation in the cabinet. In this case, on / off control of each ventilation fan is performed by a control apparatus from ventilation efficiency or an economical viewpoint.

  The control device senses the temperature and humidity inside the cabinet body, transmits the sensed signal to a control circuit, converts it into a control signal, and performs on / off control of each ventilation fan. The control device has a function of controlling the environment inside the housing within a certain range, and includes, for example, a temperature controller provided with a temperature sensor and a humidity controller provided with a humidity sensor.

  In Patent Document 1, in order to save the space for installing the ventilation fan control device inside the cabinet and perform necessary and sufficient control by matching the temperature detected by the ventilation fan control device with the temperature around the ventilation fan, a temperature sensor is installed inside the ventilation fan. A ventilation fan is disclosed that is equipped with a temperature controller.

  However, when a control device is installed inside the ventilation fan, the temperature is set for each ventilation fan, and each ventilation fan is controlled on and off independently of the other ventilation fans, enabling ideal ventilation. However, in order to control the on-off control of a ventilation fan that does not have existing control equipment, it is necessary to discard the conventional ventilation fan and replace it with a ventilation fan that incorporates the control equipment inside the ventilation fan. There were economic and environmental disadvantages.

In Patent Document 2 relating to the present application and the same applicant, a temperature controller that can be attached to the outside of the ventilation fan is disclosed as the above-mentioned problem solving means. However, the temperature controller disclosed in Patent Document 2 is for fixing the case containing the temperature control board to the outside of the ventilation fan with screws. The temperature controller having a mounting width corresponding to the mounting width of each ventilation fan is required, and there is a problem that it is inconvenient and lacks versatility.
