A thermal design evaluation method and device for a base station

Abstract

The embodiment of the invention provides a thermal design evaluation method and device for a base station, the base station comprises a board card, the board card comprises chips distributed at different positions, and the method comprises the following steps: determining a heat-sensitive position of the base station; acquiring a working temperature of a chip corresponding to the heat-sensitive position and acquiring a rated temperature of the chip corresponding to the heat-sensitive position; generating a characteristic function according to the working temperature and the rated temperature;and determining whether thermal design of the base station meets requirements or not by adopting the characteristic function. The method adopts the characteristic function for determining a fact thatwhether the thermal design of the base station meets the requirements, thus dispersibility of test data is effectively utilized; the method is easy to implement, thus design difficulty and cost are effectively reduced; and under some extreme conditions, if the actual thermal design can not meet a derating requirement but meets a rated requirement, risk information of a product in the scene is quantitatively given, and more bases are provided for decision making.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a thermal design evaluation method of a base station and a thermal design evaluation device of a base station. Background technique [0002] In the modern society where the amount of information is exploding, communication is ubiquitous, and the reliability of communication products is getting more and more attention. This also means that the product design process will encounter more challenges. The base station is a key device in the mobile communication system, and designers may face various dilemmas in product design. For example, the huge amount of data, users, coverage, etc. put forward high demands on the power of the product, and factors such as large-scale transportation and network deployment have strict restrictions on the volume of the product. The cooling function under the presents a challenge. [0003] Faced with the above problems, base station products ne...

For example, the huge amount of data, users, coverage, etc. put forward high demands on the power of the product, and factors such as large-scale transportation and network deployment have strict restrictions on the volume of the product. The cooling function under the

[0003] Faced with the above problems, base station products need to make comprehensive decisions in design, especially in thermal design. If the original derating design method is still used for thermal design analysis under some extreme environmental conditions, it will result in Under the condition that the thermal derating is met, the heat dissipation design cannot meet the given product volume limit

At the same time, the existing analysis methods do not provide a quantitative analysis method for how to conduct thermal design decisions in extreme cases. Only relying on expert decision-making is too dependent on the experience of the designer, and it is impossible to determine whether the design risk can meet the requirements.
