Abstract

The invention provides a heat-insulating airbag for a van, which belongs to the technical field of machinery. It solves the problem of poor heat insulation effect of the existing heat insulation airbags. The heat-insulating airbag used on the van includes a body with a closed air chamber, and the body is provided with an air nozzle communicating with the air chamber. It is characterized in that the body is in the shape of a rectangular plate Shape, the said inflatable cavity is provided with a plurality of flexible parts of approximately equal length, and the plurality of flexible parts are parallel to each other, and the two ends of the flexible parts are connected with the front side of the body and the The rear side is fixed. The heat insulating air bag used on the van has the advantages of good heat insulation and heat preservation effects.

Description

technical field

[0001] The invention belongs to the technical field of machinery, and relates to a heat-insulating air bag, in particular to a heat-insulating air bag used on a van. Background technique

[0002] The refrigerated van is mainly used to transport goods that require temperature, such as items that need to be kept fresh, and the refrigerated van can adjust and set different temperatures to keep the goods fresh to achieve the purpose of short-term preservation of the transported goods. At present, the existing refrigerated vans are basically equipped with airbags in the compartment, and the airbags are inflated against the inner sidewall of the compartment of the refrigerated van to form a seal, so that a seal is formed between the airbag and the inner sidewall of the compartment. Insulation cavity, the goods that need to be kept fresh are placed in the insulation cavity, so as to reduce the heat exchange between the insulation cavity and the external environment ...
