Description

Construction method of detachable vacuum insulation and fresh-keeping compartment

technical field

The invention belongs to the technical field of transportation equipment assembly, and in particular relates to a construction method of a detachable vacuum insulation and fresh-keeping compartment.

Background technique

For the transportation of fresh products in my country, especially vegetables and frozen meat, there is a serious shortage of refrigerated vehicles, and the basic investment cost is high. The difference between the place of production and the place of sale causes the vehicle to be empty, and refrigeration needs to increase fuel consumption and polluting exhaust emissions, etc., resulting in cost of use. 50% to 150% more expensive than ordinary cars. The cost of low-cost production is greatly increased after transportation, and if cold chain transportation is not used, it will bring a very high loss rate. The distance between my country's main production bases and demand cities is basically only about 10-60 hours by car. At the same time, due to the country's strong support for agriculture in recent years, the bases have relatively complete pre-cooling facilities. Most vegetable transporters have abandoned high-cost refrigerated vehicles. Using foam boxes to add bottled ice to cover quilts instead, but it is not satisfactory, so either the effect is not good, or the cost of transportation and packaging will be increased due to weight gain, and the environment will be seriously polluted.

Chinese patent CN203157821U proposes a combined insulated carriage, which is packaged with aluminum frames on four sides of a commercially available sandwich insulation board to make a top cover, a front compartment panel, a side compartment panel, a rear door and a sub-frame connected to form a rigid compartment Although this method overcomes the defects of low utilization rate and unsafe materials of the traditional integral insulation compartment insulation materials, the use of various foam insulation materials on the market is due to the high thermal conductivity (it is vacuum VIP insulation) 10 to 15 times that of the board), and the thermal insulation performance is poor. Even if it is made into a spliced car body, if there is no refrigeration mechanism, it still cannot meet the actual needs; There is no corresponding action.

At present, due to the weakness of VIP, which is afraid of puncture and impact, requires high-strength protection, and is heavy and expensive, it has not been properly and widely used in logistics.
