Temperature control system and temperature control method for flowing working medium

Abstract

The invention provides a temperature control system and a temperature control method for a flowing working medium. A temperature control system for a flowing working medium comprises a first flow adjusting branch, a first temperature control branch and a second temperature control branch, upstream pipelines of the first temperature control branch and the second temperature control branch are communicated with the first flow adjusting branch through a second water diversion tee joint, and upstream pipelines of the first temperature control branch and the second temperature control branch are communicated with the second water diversion tee joint. Downstream pipelines of the first temperature control branch and the second temperature control branch are respectively connected into the four-way switching valve and are communicated with a liquid supply port of a product to be subjected to temperature control through the four-way switching valve; a hot side cold plate is arranged on the first temperature control branch, a cold side cold plate is arranged on the second temperature control branch, and a semiconductor refrigeration assembly is arranged between the hot side cold plate and the cold side cold plate. Two paths of flowing working media are respectively heated and cooled by utilizing the efficient refrigeration efficiency of the semiconductor refrigeration assembly under the same temperature inlet condition, cold / hot mode switching is carried out through the four-way switching valve, and accurate temperature control is carried out on the flowing working media.

Description

technical field [0001] The invention relates to the technical field of temperature control equipment, in particular to a temperature control system and a temperature control method for a flowing working medium. Background technique [0002] At present, in aerospace, weapons, thermal engineering and other technical fields, there are many complex electronic devices, components, heating surfaces, etc. that need to use water cooling to dissipate heat. In the ground test, the industrial-grade water cooler is generally used to simulate the heat dissipation of the cold source; in the actual product, the direct heat exchange with the upper-level heat sink through the refrigeration cycle or the heat exchanger is used to provide the cold source for the product entrance. At present, the temperature control accuracy of industrial-grade water coolers is generally ±2°C. In actual use, due to the existence of a water storage tank inside the water cooler, the temperature cannot respond in t...
