Design Principles and Material Selection Guide for 20-Foot Insulated Containers

Insulated containers are an important tool for transporting fresh food, pharmaceuticals, or other temperature-sensitive goods. They can effectively control the temperature of the cargo, ensuring the quality and safety of the products. Therefore, when designing and selecting a20-foot insulated container, it is necessary to consider some key principles and material selection guidelines.

20-foot insulated container insulation effect priority principle

20-foot insulated container's most important goal is to maintain the stability of the cargo temperature. Hence, the insulation effect is the primary consideration in the design. The design process must consider factors such as the transportation time, distance, and changes in environmental temperature. Based on the cargo's insulation needs, suitable insulation materials and structural designs should be selected to ensure a constant temperature during transportation.

20-foot insulated container insulation material selection guidelines

20-foot insulated container insulation effect mainly relies on insulation materials. Below are some common insulation materials and their characteristics:

  • Foamed Polyurethane (PU):PU is a commonly used insulation material with good thermal performance and structural stability. It can effectively prevent heat transfer, maintaining a stable temperature for extended periods. Additionally, it has the characteristics of being lightweight and having low moisture absorption.

  • Coolant: In some cases that require lower temperature insulation, coolants can be used to enhance the insulating effect. Selecting an appropriate coolant requires considering its insulation time, cooling rate, and usage environment.

  • Metal Honeycomb Panels: Metal honeycomb panels are lightweight insulation materials with good thermal insulation performance and structural stability. They can maintain good insulation effects in harsh environments.

  • Blue Foam: Blue foam is a lightweight insulation material with excellent thermal insulation performance and impact resistance. It is suitable for situations that require high insulation effects and durability.

Choosing the right insulation material requires a comprehensive consideration of insulation requirements, usage environment, and budget.

20-foot insulated container structural design principles

In addition to the choice of insulation materials, structural design is also an important aspect of the20-foot insulated container's design. Here are some structural design principles:

  • Sealing: Insulated containers need to have good sealing performance to prevent the external temperature from affecting the internal cargo's temperature. Ensure that the joints of the box and the door seals are well-sealed to reduce heat loss.

  • Strength and Durability: Since insulated containers may face different vibrations and pressures during transportation, the structural design needs to have sufficient strength and durability. Ensure the stability of the box and pallet structures to withstand the vibrations and pressures during transportation.

  • Convenience:20-foot insulated container design needs to consider ease of use, including loading, unloading, and cleaning aspects. The design can consider the opening and closing method of the box, the setting of internal partitions, and easy-to-clean materials.

  • Weight Reduction: The weight of the insulated container also affects transportation costs and energy consumption. Therefore, structural design should consider how to reduce weight while maintaining sufficient strength and insulation effect.

In summary, the design principles and material selection guidelines for insulated containers need to prioritize insulation effects, choose suitable insulation materials, and consider structural design. The design of insulated containers needs to comprehensively consider the cargo's insulation needs, usage environment, and budget to ensure that the cargo maintains a stable temperature during transportation, ensuring the quality and safety of the product.
