AI Technical Summary

Technical Problem

Existing LNG vaporizers suffer from uncontrollable engine circulating water temperature, leading to uncontrollable LNG temperature. This can cause the LNG to freeze in low-temperature environments or overheat in high-temperature environments, resulting in engine failure.

Method used

An LNG vaporizer was designed, comprising a housing, a heat exchange module, a circulating water pipeline, a temperature detection device, and a control module. The flow rate and temperature of the circulating water are regulated by control valves and heating components to ensure that the LNG vaporizes within a suitable temperature range.

Benefits of technology

Effective control of LNG temperature avoids engine icing or overheating malfunctions, improves the safety and reliability of LNG vehicles, and enhances energy efficiency.
