Frequency conversion refrigerating system of high-power electronic equipment and control method for phase change energy storage apparatus thereof

Abstract

The invention discloses a frequency conversion refrigerating system of high-power electronic equipment and a control method therefor. The key point is that a frequency conversion refrigerating unit is connected with an evaporator in parallel; the outlet pipeline end of the evaporator is connected with a three-way valve, wherein one path is connected with a first phase change energy accumulator, and the other path is connected with a cooling liquid inlet of an external cooling apparatus of the to-be-cooled electronic equipment; the cooling liquid outlet of the external cooling apparatus of the to-be-cooled electronic equipment is connected with a second valve, wherein the second valve is a three-way valve; one path of the second valve is connected with a second phase change energy accumulator, and the other path of the second valve is connected with an inlet pipeline of the evaporator; the cooling liquid inlet and the cooling liquid outlet of the external cooling apparatus of the to-be-cooled electronic equipment are both equipped with temperature detection apparatuses; and the pipelines are pumped with refrigerating mediums. The control method is simple, and reliable operation of electronic equipment with instantaneous high thermal load can be accurately controlled.

Description

technical field [0001] The invention relates to a refrigeration system used by high-power electronic equipment such as aircraft, ships, and laser ground air defense, in particular to a control method for a frequency conversion refrigeration system of high-power electronic equipment and a phase-change energy storage device. Background technique [0002] Judging from the existing cooling devices for high-power electronic equipment, the existing patents and products have different effects in practical applications, but these devices and patents do not disclose how to solve the problems of electronic equipment with transient high power. It is a comprehensive control method for the change of the flow rate, temperature of the phase change cold storage system and the revolution number of the refrigeration system used for cooling the equipment. Due to the high value of high-power electronic equipment itself, there is no rigid requirement for energy consumption, so some cooling metho...

AI Technical Summary

Problems solved by technology

Due to the high value of high-power electronic equipment itself, there is no rigid requirement for energy consumption, so some cooling methods currently used are relatively energy-intensive, and changes in the temperature of the environment in which the equipment is located also affect its scope of use; this All of these have resulted in the difficulty of cooling high-power electronic equipment. Therefore, it is an urgent problem to provide a frequency conversion refrigeration system for high-power electronic equipment with low energy consumption and good cooling effect.
