The filler can be replaced by any one of silicon carbide fiber, aerogel and pearl wool, and the heat preservation effect can be achieved.
Furthermore, the inner side plate, the outer side plate and the middle honeycomb layer are all made of plastic materials added with carbon fibers, glass fibers and aramid fibers.
The cold chain box is characterized in that the upper cover plate, the bottom plate and the side plates are all made of the honeycomb plate with the heat preservation and sound insulation effects.
Compared with the prior art, the honeycomb plate with the heat preservation and sound insulation effects has the following beneficial effects:
1. the heat preservation and heat insulation performance of the honeycomb plate is improved: the honeycomb plate with the heat-preservation and sound-insulation effects is added with the heat-preservation and sound-insulation fillers in the splicing space, the first gap space and the second gap space of the honeycomb plate, improves the heat-preservation, sound-insulation and heat-insulation properties of the honeycomb plate in the prior art, does not change the basic structure of the honeycomb plate, and can still keep good compressive strength and shock resistance of the whole plate.
2. The strength and the deflection of the honeycomb plate are improved: abandon original ordinary plastics material, interior plate, outer panel, middle honeycomb layer all adopt to add carbon fiber, glass fiber and aramid fiber's plastics material to make, make the intensity, the amount of deflection performance of honeycomb panel good, and then make products such as cold chain case that the honeycomb panel supported more durable, circulated use.
3. Environmental protection and economy are considered: the filler is made of cotton or polyurethane foam, is environment-friendly, has controllable cost and is convenient to popularize and apply in practical production.
