There are still three months before the college entrance examination, and many students have already begun to work hard for their own future. At the same time, many schools are stepping up their preparations. In order to provide students with a fair and just environment, they have already begun to prepare for the layout of the examination room in March. Among them, one of the more important equipment in the layout of the examination room is definitely inseparable from our full-band test room signal shielding device. This kind of equipment is mainly used to shield all mobile, telecommunications, China Unicom and other network signals in the test room, so as to avoid someone using mobile phones to cheat during the test. Therefore, the test room equipped with a full-band test room signal shielding device can effectively avoid this situation.
In fact, it is not new to install a full-band test signal shielding device in the examination room. However, the development of communication technology is too fast now, and some equipment cannot be upgraded and maintained. Some equipment will become hot after being used for a long time. The heating of the equipment may greatly affect its normal effect. If the full-band test room signal jammer gets hot and does not deal with it urgently, it will cause frequency deviation of the cell phone signal jammer. Furthermore, when the machine is just started to use, the mobile phone signal can be normally shielded, but some mobile phones cannot be shielded after working for a period of time. Therefore, the heat dissipation level of the full-band test room signal shielding instrument should be considered when installing and applying. The full-band test room signal shielding instruments of the same brand also have differences in heat dissipation. So which method does the full-band test room signal shielding instrument dissipate heat? The previous traditional full-band test room signal shielding instrument can only rely on the natural environment temperature to cool down slowly. But now, most of the full-band test room signal shielding instruments will open the heat dissipation hole group to assemble the heat dissipation fan, which can help the equipment to reduce the ambient temperature as soon as possible. However, due to the different electronic components used by different manufacturers, the noise level generated by this fan during operation is also different. The full-band test room signal shielding instrument manufactured by Chengdu 8341 Information Technology Co., Ltd. uses a more professional air supply mode. At high temperature, the heat transfer process can be quickly transferred to the heat dissipation base to prevent the heat generation part from being deposited. Four fans are installed on the heat dissipation base to quickly blow the heat to the top, and the fans on both sides of the top are quickly discharged. The cooling fan used in the full-band test room signal shielding instrument not only reduces noise during operation, but also has a good cooling effect and can work continuously for a long time to ensure smooth output of each frequency band. This setting is more suitable for providing students with a quiet and natural testing environment during the exam.
