Abstract

The invention a temperature control device of a multipath liquid cooling system, and belongs to the technical field of cooling of high-performance aircraft equipment. A liquid pump, a check valve, a heat exchanger and a temperature adjusting valve are sequentially connected on a main liquid pipeline, wherein the temperature adjusting valve is connected with the heat exchanger; the main liquid pipeline can be divided into a plurality of branches to perform heat-exchange cooling with equipment to be cooled on the branches, a secondary liquid pipeline is divided into a plurality of branches, and a circulating pump is arranged in each of the branches; a system control device is connected with a sensor, the circulating pumps, a feed liquid temperature sensor, the liquid pump and the temperature adjusting valve; a temperature value required by the equipment to be cooled is set in the system control device; the opening degree of the temperature adjusting valve is controlled to adjust the liquid temperature of the main liquid pipeline; and the rotating speed of the circulating pumps of the branches is controlled by the system control device, so that the liquid flow is adjusted. According to the temperature control device of the multipath liquid cooling system disclosed by the invention, different thermal loads of t the high-performance aircraft equipment are taken away by a single-phase liquid loop system, so that the energy utilization of the system is optimized, the system control is precise, and the system performance compensatory loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of high-performance aircraft equipment cooling, and in particular relates to a temperature control device for a multi-channel liquid cooling system. Background technique [0002] At present, the main technologies applied in the field of aircraft equipment cooling at home and abroad include air circulation cooling technology and liquid loop cooling technology. [0003] Air circulation cooling technology is widely used in various types of aircraft equipment cooling systems, but the cooling performance coefficient is low, and the reliability of the system is poor when the ground is shut down. In addition, due to the introduction of external ram air, the operating height and speed are limited. , these are in contradiction with the characteristics of large heat load of high-performance aircraft equipment. [0004] Liquid loop cooling technology belongs to indirect cooling, and the intermediate coolant is liquid....
