| Abstract: |
| The work aims to investigate the impact of the low-temperature environment on the operation and startup characteristics of the liquid cooling system for pod. Based on a certain type of pod liquid cooling system, the scenarios from –55 ℃ to 25 ℃ were simulated and the experimental research was carried out to study the impact of temperature on the liquid supply pressure, the liquid level of the expansion tank, the steady-state current and power, and the instantaneous startup current. The liquid supply pressure firstly increased and then decreased as the temperature dropped, reaching the maximum pressure of 469.74 kPa at 5 ℃. The liquid level of the expansion tank gradually decreased as the temperature dropped, and the decline was significant within the range of 25 ℃ to 5 ℃. The steady-state current and power gradually increased as the temperature dropped. The power supply current increased from 3.6 A to 8.1 A, and the power supply power increased from 100.8 W to 226.8 W, with an increase amplitude of 125%. The instantaneous startup current gradually increased as the temperature dropped, from 5.44 A to 13.40 A, and was significantly greater than the steady-state current at the corresponding temperature. Low temperature causes the system volume to shrink and the viscosity of the coolant to increase. The design of the liquid cooling system for pod needs to fully consider the risks of cavitation and overcurrent. |
