Regulation and control method of split type high-precision liquid cooling source system based on standardization

Abstract

The invention discloses a regulation and control method of a split type high-precision liquid cooling source system based on standardization. The liquid cooling source system comprises a first-stage liquid cooling source module, a second-stage liquid cooling source module, a cooling cycle working medium and an external equipment module, wherein the first-stage liquid cooling source module cools the cooling circulation working medium in the second-stage liquid cooling source module through a heat exchange device, the second-stage liquid cooling source module regulates and controls the temperature of the external equipment module through the cooling circulation working medium; and when the set temperature of the second-stage liquid cooling source module is the temperature required by the external equipment module, in order to realize that the temperature control precision of the external equipment module reaches an ideal requirement, the temperature control precision of the external equipment module is met by adjusting the set temperature of the first-stage liquid cooling source module, that is to say, if the temperature control precision of the second-stage liquid cooling source module exceeds an ideal value, the temperature of the first-stage liquid cooling source module can be reset to compensate the exceeding part. The regulation and control method of the liquid cooling source system can meet the requirements of various different external equipment modules.

Description

technical field [0001] The invention belongs to the field of aerospace liquid cooling sources, and in particular relates to a control method based on a standardized split-type high-precision liquid cooling source system. Background technique [0002] Liquid cooling source is a commonly used device that provides a certain temperature, pressure, and flow of cooling fluid for equipment that adopts liquid cooling. Because of its high cooling efficiency and relatively simple technology, it has been widely used. It is used in aerospace supporting equipment Cooling occupies a large proportion, especially the thermal control equipment in each test unit, module and system, such as cabinets, high-power electronic devices and other equipment, all need cooling fluid for equipment cooling. At present, there are three main types of liquid cooling sources on the market: (1) liquid cooling sources for laser welding, material forming, mechanical cutting, etc.; (2) liquid cooling sources for ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the target temperature control method of the external equipment equipped with a liquid cooling source usually directly uses a single liquid cooling source device for temperature control, and uses a single liquid cooling source device to regulate the target temperature of the external device. Since a single liquid cooling source device The single-stage compressor start-stop method is used to control the temperature accuracy of external equipment, which affects the life of the compressor. In the cooling process of the single-stage compressor, when the temperature reaches the set value, the compressor starts and stops frequently, causing thermal inertia. Large, resulting in large temperature fluctuations, which cannot meet the temperature accuracy control of the target temperature, so this control method cannot meet the temperature accuracy requirements of the target temperature of the external equipment, and it is urgent to improve this control method
