A modular water-cooled cabinet and its noise redundancy control method

Abstract

The invention discloses a modularized water-cooling cabinet and a noise redundancy control method thereof. The water-cooling cabinet comprises a display control unit, a heat-exchange refrigeration unit, a pressure conversion unit, a fault alarm, dampers and a water supplement tank. The heat-exchange refrigeration unit comprises redundancy metering pumps, a water-cooling heat exchanger, semiconductor refrigerating pieces, cooling fins, fan components, switching electromagnetic valves, a control signal conversion module, a water inlet temperature sensor and a water outlet temperature sensor. The display control unit collects temperature values and flow values of the heat-exchange refrigeration unit, temperature values of external water-cooling electronic equipment, environment temperature values and pressure values of the pressure conversion unit in real time, judges and displays the working state of the water-cooling cabinet, and outputs control signals to the heat-exchange refrigeration unit after calculating of temperature difference values between water-outlet cooling water temperature values and preset temperature values. On the premise of guaranteeing heat dissipation capability of the water-cooling cabinet or temperature rise of the external water-cooling electronic equipment, currents of the semiconductor refrigerating pieces and voltages of the fan components in radiating assemblies are dynamically adjusted and controlled in a redundancy mode so as to control noise of the water-cooling cabinet.

Description

technical field [0001] The invention belongs to the technical field of anti-harsh environment computers, in particular to a modularized water-cooled cabinet and a noise redundancy control method thereof. Background technique [0002] With the continuous development of electronic technology and large-scale integrated circuit technology, the power consumption and heat per unit volume of electronic equipment continue to increase. At present, electronic equipment working in harsh environments generally adopts forced air cooling technology. Although the structure is simple and the cost is low, High reliability, but due to the limitations of the working environment of electronic equipment, equipment volume, noise requirements, etc., air-cooled heat dissipation systems generally have low heat dissipation capabilities, which cannot meet the heat dissipation requirements of high-power, high-performance electronic equipment. [0003] As a relatively mature heat dissipation technology,...

AI Technical Summary

Problems solved by technology

[0004] Existing water-cooled cabinets are mostly used in large-scale computer rooms or high-end server fields. Although the heat dissipation capacity is much higher than that of air-cooled heat dissipation systems, they generally have disadvantages such as complex structure, poor maintainability, loud noise, and weak environmental adaptability. They lack the ability to adjust the cabinet according to environmental temperature changes. Noise function, it is difficult to meet the high reliability requirements for heat dissipation of electronic equipment working in a strong vibration environment, which limits the application field and use range of water-cooled cabinets and water-cooled electronic equipment
