Problems solved by technology

[0006] Due to the large size of the power amplifier, it is necessary to build a large number of special high-temperature aging rooms when producing power amplifiers in large quantities. At the same time, because the high-temperature aging room needs good sealing to maintain a constant temperature, it provides real-time monitoring of the working status of the power amplifier during the aging process. Monitoring brings a lot of inconvenience. If the power amplifier breaks down during the aging process, it is difficult to find it in time. Generally, only after the long-term aging process is over, when the power amplifier is tested, can the power amplifier with problems be found and repaired, not only Causes invalid aging process, delays time, wastes resources such as electric energy and the space of high-temperature aging room
[0007] In summary, due to the high construction cost of the high-temperature aging room, the use of a large amount of energy such as electricity for heating, and the unnecessary aging process of the existing methods for power amplifier aging, the aging efficiency of the power amplifier is low and the production cost is high. Become the bottleneck of mass production of amplifiers

Embodiment Construction

[0035] Electronic equipment will generate a certain amount of heat when it is working. High-power electronic equipment will generate a lot of heat when it is working, especially when it is working at its rated output power. For example, the power amplifier of a base station in a wireless communication system, its It is a high-power module itself, and it generates a lot of heat under working conditions.

[0036] In order to dissipate the heat generated by electronic equipment in time and provide a suitable temperature working environment for electronic equipment, general electronic equipment will be equipped with cooling devices, such as cooling fans, cooling holes, cooling fins, etc.

[0037] The present invention utilizes the features such as the heat generated by the electronic equipment during work and the heat dissipation device to realize the aging of the electronic equipment under the normal temperature environment.

[0038] The core of the present invention is: make the...

Abstract

The invention provides an aging method based on the electric device with heat receiver, which makes the electric device on working condition at normal temperature environment and controls the heat receiver of the electric device to age the electric device.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an aging method for electronic equipment based on a cooling device. Background technique [0002] In the base station of the wireless communication system, the power amplifier is one of the modules with the largest power, the most complex technology, the largest number of configurations and the most expensive price. [0003] According to the characteristics of electronic products, the life cycle curve of power amplifier is as attached figure 1 shown, from figure 1 It can be clearly seen from the figure that the failure rate of the power amplifier in the initial stage of use, that is, the early failure period, is very high. After the early failure period, when the power amplifier enters the service life of the power amplifier, the power amplifier enters a reliable working period, and the failure rate is approximately As a constant, the power amplifier runs smoothly ...
