The invention discloses an LNG (Liquefied Natural Gas) cold energy utilization device. A heat exchange cavity and a primary cooling cavity are formed in a shell; the heat exchange cavity comprises a first ice making cavity and a second ice making cavity arranged on the outer side of the first ice making cavity; at least one group of paired heat exchange sheets are arranged in the first ice making cavity, and a gap is formed between the two heat exchange sheets in each group and serves as an air channel; the inner sides of the heat exchange pieces are connected with single-side fin flat pipes in an attached mode, a water inlet is formed in the top of the shell, an ice scraping conveying mechanism is arranged on the outer sides of the heat exchange pieces and makes contact with the side walls of the heat exchange pieces, and ice layers attached to the side walls of the heat exchange pieces are scraped off and then conveyed to the second ice making cavity; a broken ice cooling mechanism is arranged at the bottom
