Description

Cooling devices and communication equipment

Technical field

The present invention relates to the technical field of communication devices, specifically heat dissipation devices and communication equipment.

Background technique

Communication equipment refers to equipment used to realize information transmission and communication. For some communication equipment, such as walkie-talkies, communicators, etc., their working process will generate a large amount of heat. If this heat cannot be effectively dissipated, the equipment will be damaged due to overheating or even fail to work properly. Therefore, the heat dissipation device plays a key role in these equipment to help keep the temperature of the equipment within an acceptable range and ensure Its functioning normally.

After searching, the Chinese invention patent application with publication number "CN115443039A" disclosed "a communication equipment". This application enhances the heat dissipation capacity of communication equipment by installing fin radiators.

In addition, the Chinese invention patent application with publication number "CN108601308A" discloses "an adjustable heat dissipation device for electronic products." The application adjusts the inclination angle of the device according to the actual needs of different users and uses a cooling fan to The mobile phone performs auxiliary heat dissipation to prevent the mobile phone from overheating and damaging internal components.

When traveling outdoors in arid or mountainous areas, the temperature of the user's environment will gradually increase during the day and the temperature difference between night and daytime will be large. Due to the gradual increase in the temperature of the surrounding environment during the day, the temperature will be higher than normal during the day. The temperature of the walkie-talkie is designed to dissipate heat, so the cooling effect of using a fan is limited. Directly using a fin radiator for heat dissipation will increase the storage power consumption of the walkie-talkie due to the addition of new heat dissipation equipment. In addition, it cannot be used in outdoor environments. Timely power replenishment, so high power consumption will also reduce the battery life of the device, resulting in the risk of power outage for long-term travel. In addition, if the fin radiator is directly placed inside the walkie-talkie, it will also increase the overall weight of the walkie-talkie. , which is fatal for outdoor travel, especially adventure travel in extreme environments.

To this end, the applicant proposed a heat dissipation device that can be flexibly assembled according to the real-time temperature of the environment, and a communication device adapted to the heat dissipation device to solve the above existing problems.
