Waste cold recycling system of LNG power carrier

Abstract

The invention relates to a waste cold recycling system of an LNG power carrier. The waste cold recycling system of the LNG power carrier comprises an LNG power traction head, a refrigerator van and a cold source transferring tank; an LNG cycle power system is installed in the LNG power traction head; the LNG power traction head pulls the refrigerator van for transportation; the cold source transferring tank is installed on one side of the LNG power traction head; the cold source transferring tank is full of transferring liquid; the head of a gas bottle of an LNG circulating system is installed in the cold source transferring tank; a coiled pipe is installed in the cold source transferring tank; and the two ends of the coiled pipe extend out of the cold source transferring tank in a sealed mode and are in flexible connection or hard connection with a liquid inlet and a liquid outlet of a heat exchanger. Only the heat exchanger is installed on the portion, close to the vehicle head, of the side wall of the refrigerator van, a fan is installed in front of the heat exchanger, and heat of the heat exchanger can be transmitted into the whole refrigerator van as soon as possible. A refrigerated truck provided by the invention can provide ultra-long-distance transportation, a truck body is provided with a real-time refrigeration device, other energy sources are not consumed, energy is saved, and consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, in particular to a temperature control device for waste cold recovery of LNG powered vehicles. Background technique [0002] For example, LNG vehicle is short for liquefied natural gas vehicle. LNG vehicles are a new generation of natural gas vehicles fueled by low-temperature liquefied natural gas. The outstanding advantages of LNG are its high energy density (about 3 times that of CNG), and its long driving range, which can reach more than 400km. Compared with diesel and gasoline, it has advantages. Significant economic benefits. [0003] The LNG vehicles targeted by this application are cooled in large quantities during the vaporization process of the low-temperature liquefied natural gas in the engine, resulting in very serious pipeline icing. If it is found, it will be manually removed, resulting in a lot of waste of cold sources. Contents of the invention [0004] The purpose of ...
