In particular, the features of this embodiment are transparently shown with dotted lines. FIG. 2 is a diagram showing how the plunger operates due to temperature changes and the shirt shirt plate connected to the plunger moves. FIG. 3 is a side sectional view taken along line 1--2 in FIG. FIG. 4 is a circuit diagram showing the control circuit of the embodiment of FIG. 3. In the figure, 1 is a plunger, 2 is a shirt plate, 3 is a rail, 10 is an equipment case, 11 is a heat radiation hole, and 21 is a hole formed in the shirt shirt plate.

Claims

[Scope of utility model registration request]

(1) In an equipment case that houses a heat source inside and has holes for heat radiation formed in the wall of the case, there is a sliding shutter plate provided along the inner wall of the case, and the shirt flap. and a plunger connected to, when the temperature inside the case is lower than a predetermined temperature, the heat radiation hole is closed by the shirt shirt plate, and when the temperature inside the case is higher than a predetermined temperature, the plunger is closed. The equipment case is configured such that when activated, the shutter plate slides and the heat radiation hole opens.

(2) The shirt shirt plate has holes of the same shape and arrangement as the heat radiation holes formed on the case wall surface, and when the shirt shirt plate slides, the heat radiation holes of the case and the holes of the shirt shirt plate are connected. The heat dissipation holes of the case are opened accordingly (the equipment case according to claim 1 of the utility model registration).

(3) A plurality of the shirt shutter plates and plungers connected to the shirt shirt plates are provided, and the plungers are sequentially activated in response to a temperature rise within the case. The equipment case described in paragraph 1 or 2.
