Description

Technical Field

[0001] The invention relates to the field of transport vehicles, and in particular to an electrically heated and heat-insulated transport vehicle. Background Art

[0002] Thermal transport vehicles are vehicles specially designed to ensure that goods are kept at a suitable temperature during transportation. Such vehicles are usually equipped with special thermal insulation compartments to effectively protect the materials inside the compartments and ensure their quality and safety. Thermal transport vehicles play a vital role in many industries, especially in the construction field. They not only need to be able to maintain the temperature of the goods, but also need to cope with various external environmental changes, especially in cold weather or low-temperature areas.

[0003] During long-distance transportation, this temperature drop may cause the materials in the carriage to solidify due to the low temperature. This phenomenon not only affects the physical properties of the materials, but may also have a serious impact on the subsequent construction process. The solidified materials may not be mixed evenly during use, and may even cause the construction machinery to be blocked, thereby delaying the project progress and increasing construction costs.

[0004] At present, for insulated transport vehicles used for road construction, the temperature of materials in the compartment is mainly controlled by using insulation materials. Usually, these insulation materials such as insulation cotton, polyurethane foam, etc. are widely used in the design of the compartment to reduce heat loss and achieve the insulation effect. However, in actual applications, these insulation materials may not perform as expected in extremely cold environments. Especially in the cold winter season, when the external temperature is below freezing, the insulation effect of the insulation cotton will be significantly reduced, which often causes the temperature of the materials in the compartment to drop accordingly.
