Description

Technical Field

[0001] This utility model belongs to the field of cryogenic material production technology, specifically relating to a vehicle-mounted cryogenic storage tank. Background Technology

[0002] In modern industry and daily life, the demand for the transportation and storage of cryogenic materials is increasing. In the chemical industry, many special chemical raw materials need to be stored and transported in a low-temperature environment to maintain the stability of their chemical properties. In the food cold chain industry, large quantities of frozen foods and fresh ingredients need to be transported over long distances using cryogenic storage tanks to ensure that their quality is not affected. In the medical industry, the transportation of biological products such as blood products and vaccines has strict requirements for cryogenic environments. Temperature fluctuations may cause these products to lose their activity, thereby affecting medical treatment and disease prevention and control.

[0003] Patent application CN202221698701.3 discloses a vehicle-mounted double-layered cryogenic storage tank for simultaneously storing two cryogenic liquids with different physical properties: liquid nitrogen (-196°C) and pentafluoropropane (-45°C). The two storage spaces are designed to be separate, isolating them from each other and providing effective thermal insulation. The liquid nitrogen storage space has a built-in submersible pump that directly draws liquid nitrogen for heat exchange on the work platform, and the liquid nitrogen returns to the tank after heat exchange, forming a cycle. The pentafluoropropane storage space uses an external heat exchange pump, with the output returning to the lower tank, forming a cycle as well.

[0004] However, the cryogenic storage tanks proposed in the aforementioned document have several shortcomings in meeting the needs of vehicle-mounted transportation. Firstly, these tanks are fixed and lack a connection structure for docking with vehicles, making it inconvenient to secure them and hindering flexible mobile transportation. This makes it impossible to meet the urgent needs for cryogenic materials at different locations. Secondly, although the vehicle-mounted cryogenic storage tanks can store two sets of materials, this exchange of heat between the two sets increases refrigeration energy consumption and may cause the temperature of the cryogenic materials to exceed the permissible range, affecting material quality and preventing rapid cooling to the required temperature, thus delaying transportation time.
