ージヤー。[Scope of Claim for Utility Model Registration] (1) An enclosure that surrounds the engine so as to block noise generated from the engine, and a ventilation fan that cools the inside of the enclosure by supplying air to the inside of the enclosure. and a sensor that detects the temperature inside the enclosure, the control device controls the ventilation fan according to the output from the sensor, and the output from the sensor The controller activates the ventilation fan when the temperature inside the enclosure indicates that the temperature is above a predetermined level, and the controller activates the fan when the output from the sensor indicates that the temperature inside the enclosure is below a predetermined level. An enclosure that does not operate the ventilation fan. (2) An enclosure according to claim 1 of the utility model registration, in which an enclosure internal temperature control operation stop signal is inputted from the outside to the control device, and the enclosure internal temperature control operation stop signal is inputted to the enclosure, and the enclosure is controlled in accordance with the temperature control operation stop signal. The device does not operate the ventilation fan even when the output from the sensor indicates that the temperature inside the enclosure is above a predetermined level. (3) An enclosure according to claim 1 of the utility model registration claim, in which a ventilation fan forced operation signal is input to the control device, and in response to the forced operation signal, the control device operates regardless of the output from the sensor. An enclosure that allows the ventilation fan to operate. (4) An enclosure according to claim 1 of the utility model registration, which detects from a sensor when a driving current of a predetermined level or higher flows through the ventilation fan, or that the temperature inside the enclosure exceeds a predetermined level. The control device indicates to the outside that an abnormality has occurred when the output of the ventilation fan is indicated and no driving current flows to the ventilation fan, or when no current is supplied to the control device. (5) An enclosure according to claim 1 of the utility model registration, wherein the predetermined level of temperature inside the enclosure is set at the upper limit of the ambient temperature range that allows proper operation of the engine. , enclosure.
