发明名称 Protecting device for protecting an electronic equipment in order to use the electronic equipment under a hostile environment.
摘要 <p>A protecting device is for use in protecting a radio communication device (15) under high and low temperature. The protecting device comprises a cover member (31) of a heat insulator that defines a room therein. The radio communication device is located in the room. First and second opening portions (31a, 31b) are formed at the cover member. The first opening portion may be opposite to the second opening portion. Each of the first and the second opening portions has a predetermined opening area. The protecting device further comprises first and second damper members (32a, 32b) and has first and second driving sections (33a, 33b, 34a, 34b). The first driving section drives the first damper member in accordance with a room temperature to make the first damper member vary the predetermined opening area into a variable opening area in the first opening portion. The variable opening area is smaller than the predetermined opening area. Similarly, the second driving section drives the second damper member in accordance with the room temperature to make the second damper member vary the predetermined opening area into the variable opening area in the second opening area. &lt;IMAGE&gt;</p>
