戻される。Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan cross-sectional view showing one embodiment of the present invention, and FIG. 1 is a cross-sectional view taken along line nn in FIG. Components that are the same as or corresponding to those in FIGS. Ventilators 11 (A) for supplying outside air to ventilate the interior of the vehicle body (1) are attached to the vehicle body (1) at one location at the front and one at the rear. This ventilation M (4), which has a filter (not shown) attached to the front part, is connected to a ventilation fan control device (not shown) that operates a ventilation fan (6) according to the temperature inside the vehicle body (1). has been done. As can be seen from the block diagram shown in Figure 3, the ventilation fan control device includes temperature detectors (TE) installed at multiple locations inside the vehicle body (1) to detect the air temperature, and a It is equipped with a ventilation fan control circuit (IQ) which is a variable voltage, variable frequency type inverter circuit that continuously and variably controls the ventilation fan (6) in response to a signal. The ventilation fan (,) is rotated a predetermined number of times by the action of the ventilation fan control device and the ventilation fan power supply (lI). Additionally, above the cooling fan (3) there is a vent (r
) is provided. When the ventilation M (A) is rotating at maximum output, the air that entered the vehicle body (1) from the ventilation M (6) is released into the outside air through the exhaust port, and the ventilation fan (6) stops rotating. When the cooling fan (3) is running, the air sucked into the cooling fan (3) is returned into the vehicle body (1) through the vent (r).

体（１）内に戻される空気量は増大する。In the electric locomotive constructed as described above, outside air is supplied into the car body (1) through the ventilation fan (3) according to the temperature inside the car body (1), and the temperature is, for example, lIo.
When the temperature is as high as ℃, the ventilation fan (6) rotates at full power, supplying a large amount of outside air into the vehicle body (1), cooling the electrical components (k), and releasing it into the outside air from the exhaust port (lI). be done. As the temperature inside the car body (1) gets lower, the ventilation fan (6
) decreases and the amount of outside air supplied into the vehicle body (1) also decreases, but the amount of air returned into the vehicle body (1) through the vent CI> increases accordingly.

品（２）の冷却に用いられる。When the outside temperature is as low as -qo℃, K means ventilation J! I (A) does not operate and outside air is not supplied to the vehicle body (1). Therefore, the original air heated by the cooling of the electrical components (C) is not discharged to the outside from the exhaust port (Cx), but is supplied into the vehicle body (1) through the vent port (Cx), and is then heated again. Used for cooling electrical equipment (2).

ができる。In addition, in the above embodiment, the ventilation fan control device in which the rotation speed of the ventilation fan (6) is continuously variable controlled was explained, but the ventilation fan control device is configured with a non-contact type device such as an inverter device and can operate frequently. In this case, the continuously variable control described above can be replaced with ON/OFF control with a certain temperature range.

なされるという効果もある。As described above, according to the present invention, the operating output of the ventilation fan fluctuates depending on the temperature inside the car body, and it is possible to avoid supplying more outside air than necessary into the car body. The amount of dust entering the outside air will be reduced, and the frequency of accidents such as malfunctions of electrical appliances due to dust and noise will be reduced. Furthermore, since the temperature inside the vehicle body remains constant without being affected by the outside temperature, there is also the effect that electrical components can operate stably and reliably without being affected by the outside temperature.
