Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 and figure 2 A vehicle-mounted liquid nitrogen spray refrigeration system is shown, including a compartment 1 and a liquid nitrogen storage tank 21. The interior of the compartment 1 is provided with a liquid nitrogen atomization spray mechanism, and the liquid nitrogen atomization spray mechanism passes through the tube The road 22 is connected to the liquid nitrogen storage tank 21. The liquid nitrogen atomization spray mechanism includes a first spray pipe 23 and a second spray pipe 24 arranged on the inner roof of the compartment 1. The first spray pipe 23 Several atomizing nozzles 25 are arranged on the second spray pipe 24 and the second spray pipe 24 .

[0027] The first spray pipe 23 and the second spray pipe 24 are parallel, and are respectively arranged on both sides of the inner roof of the compartment 1, and the se...

Abstract

The invention discloses a car-mounted liquid nitrogen spraying and refrigerating system which comprises a compartment and a liquid nitrogen storage tank. A liquid nitrogen atomizing and spraying mechanism is arranged in the compartment and connected with the liquid nitrogen storage tank through a pipeline, and a human body induction mechanism is further arranged in the compartment and connected to a single-chip microcomputer. The car-mounted liquid nitrogen spraying and refrigerating system has the advantages that a liquid nitrogen atomizing and spraying pipeline connected with the liquid nitrogen storage tank is arranged at the top of the compartment, it is guaranteed that liquid nitrogen is fully atomized and absorbs heat to form nitrogen, and it is avoided that liquid nitrogen drops drop onto a product, and consequently the product is freeze-damaged. The personnel recognition device is arranged in the compartment, it is guaranteed that atomizing and spraying are carried out under the condition that no person exists, and casualty accidents caused by misoperation are effectively eradicated.

Description

technical field [0001] The invention relates to the field of van refrigerated vehicles, in particular to a vehicle-mounted liquid nitrogen spray refrigeration system. Background technique [0002] According to the refrigeration method, refrigerated trucks are mainly divided into five methods: mechanical refrigeration, dry ice refrigeration, water ice salt ice refrigeration, cold storage plate refrigeration, and liquid nitrogen refrigeration. At present, mechanically refrigerated refrigerated vehicles occupy the main refrigerated vehicle market. They are used in many occasions and have the advantages of uniform temperature and simple operation, but they also have complex structures, prone to failure, high maintenance costs and cooling speed. Slow, not energy-saving and environmentally friendly, and the refrigeration temperature is about minus 30°C. [0003] Choosing different refrigeration systems has very important practical significance for refrigerated truck transportatio...
