Title:
EXTERNAL WATER CIRCULATION TEMPERATURE CONTROL SYSTEM FOR FUEL CELL FIXTURE
Document Type and Number:
WIPO Patent Application WO/2021/103173
Kind Code:
A1
Abstract:
The present invention relates to the technical field of battery manufacturing, and particularly relates to an external water circulation temperature control system for a fuel cell fixture. The system of the present invention comprises a fixture provided with a water inlet and a water outlet in mutual communication with each other. The water outlet communicates with a constant-temperature water mixing container via a first circulation water pump, and the constant-temperature water mixing container is provided with a first temperature sensor. A hot water delivery pipeline used to deliver hot water into the constant-temperature water mixing container and a cold water delivery pipeline used to deliver cold water into the constant-temperature water mixing container are provided between the first circulation water pump and the constant-temperature water mixing container. The constant-temperature water mixing container communicates with the water inlet via a second circulation water pump. The water circulation temperature control system provided by the present invention ensures fixtures are maintained at a constant temperature, thereby improving reliability of test results. In addition, the present invention uses a data acquisition and analysis system and a control system to achieve data acquisition and control for flow volumes and temperatures, thereby enabling automation of a control process, and guaranteeing production efficiency.
