LNG vaporization assembly, control method of LNG vaporization assembly and vehicle

The invention belongs to the technical field of LNG vaporization, and discloses an LNG vaporization assembly, a control method of the LNG vaporization assembly and a vehicle, the LNG vaporization assembly comprises an air compressor, a high-pressure gas storage tank and an engine, and further comprises a gas bath heating mechanism, a water bath heating mechanism and a gas pipe. The gas bath heating mechanism comprises a gas tank, a gas inlet part of the gas tank is communicated with a compressed gas outlet of the air compressor, and a gas outlet part of the gas tank is communicated with the high-pressure gas storage tank; the water bath heating mechanism comprises a liquid tank which is communicated with the engine, and engine cooling liquid can flow through the liquid tank and flow back to the engine. The gas pipe sequentially penetrates through the gas tank and the liquid tank, LNG passes through the gas pipe, and the gas pipe can be heated by the compressed gas and the engine cooling liquid.
