What specific contribution does the design of the Stretched Type Evaporator make to improving the cooling effect?

The Stretched Type Evaporator provides a larger heat exchange area by increasing its length. This allows the refrigerant to exchange heat with the air more fully inside the evaporator, absorb more heat, and thus improve the cooling effect. The larger surface area allows the refrigerant to absorb heat from the air more effectively during the evaporation process, thereby achieving faster cooling.
In the Stretched Type Evaporator, the flow path of the refrigerant is designed more reasonably, which helps the refrigerant to be evenly distributed inside the evaporator and improve the heat exchange efficiency. At the same time, the appropriate length can ensure that the refrigerant is fully evaporated in the evaporator and avoid the refrigerant being still in liquid state at the outlet of the evaporator, which affects the cooling effect.
The Stretched Type Evaporator is often accompanied by the optimization of the air outlet design, such as the stretched air outlet design, which can increase the wind pressure, make the air supply range farther, and the cooling effect better. By improving the air supply efficiency and range, the Stretched Type Evaporator can ensure that the cold air can be quickly and evenly distributed to the area that needs to be cooled, thereby improving the overall cooling effect.
The Stretched Type Evaporator can meet the cold storage with different temperature requirements. For example, for cold storage with a storage temperature of about 0℃, it is suitable for storing fresh eggs, vegetables and other items; for cold storage with a storage temperature of about -18℃, it is suitable for freezing beef, mutton, fish and seafood; and for cold storage with a storage temperature of -25℃ and below, it is mainly used for quick freezing of poultry, livestock, seafood and dairy products. This adaptability enables the Stretched Type Evaporator to perform excellent cooling effects in a variety of application scenarios.
Although the Stretched Type Evaporator has significant advantages in improving the cooling effect, an overly long evaporator may also cause the refrigerant to flow in the evaporator for too long, reducing the evaporation amount and reducing the cooling efficiency. Therefore, when selecting the length of the evaporator, it is necessary to weigh the relationship between the cooling effect and the cooling efficiency to obtain the best cooling solution.
