Heating circuit board based on edge server

Abstract

The invention relates to the technical field of servers, and provides a heating circuit board based on an edge server, which comprises a power supply and control circuit, a heating mechanism, a microcontroller, an actual voltage acquisition and processing circuit, a reference voltage conversion circuit, a voltage comparator U6 and a signal multiplexer U5, the power supply and control circuit is used for controlling the power-on state of the heating mechanism according to the level of an enable signal CON_1 generated by the signal multiplexer U5, and the actual voltage collecting and processing circuit and the reference voltage conversion circuit are used for obtaining actual comparison voltage CON_2 and reference voltage respectively. The voltage comparator U6 and the signal multiplexer U5 are combined with the microcontroller to realize an adjustable scheme of heating power, so that the electric heating efficiency in a low-temperature environment is improved, the control logic and code quantity are simplified, the burden of a control system is relieved, and the stability and safety of the system are improved.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a heating circuit board based on an edge server. Background technique [0002] With the rapid development of edge computing related technologies, informatization has gradually covered all fields of society, and promoted the landing of edge servers in industries such as petroleum and electric power, thereby greatly expanding the application scenarios of servers. my country has a vast territory, and the above-mentioned industries involving energy exploration have put forward new requirements for the stability and reliability of edge servers in high and low temperature environments due to the wide range of working environments and usage scenarios. [0003] For the extremely low temperature deployment environment where the ambient temperature can reach as low as -40°C and the temperature of the server box is even lower, since some electronic components do not have the cha...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a heating circuit board based on an edge server, aiming to solve the deficiencies in the reliability and use effect of the way of deploying the heating sheet at the bottom of the board in the prior art. There will be a local overheating problem on the bottom surface of the circuit board, and because it is close to the casing, the heat loss is fast, and the heating effect is not ideal.
