Our factory specializes in the production of phase change material energy storage ball, after continuous innovation and improvement of the head upgrades, the inner plug is rubber, the energy storage ball containing organic phase change material is fluorinated. the product package adopts one inner plug and one outer cover.
can be used for a long time and can ensure that the product does not leak.
For customers who want to fill their own phase change materials, a filling machine is required, the product packaging is very convenient, no tools needed and affordable, organic empty balls cost $0.42 and inorganic empty balls cost $0.15, to provide customers with simple, convenient, but also for customers to achieve low cost, high efficiency.
The multi-sided prismatic ball on the market comes from the factory design and production, welcome technical exchange and inquiry.
We provide products free mold opening (The mold fee will be refunded if the order amount of each product is more than 5000 USD).
Polyhedral prism ball, after long-term use and feedback from customers, equipped with phase change material diameter is too large, the phase change material in the middle of the ball has a waste phenomenon.now the energy storage ball produced by our factory does not appear this phenomenon.
Phase change material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa; thus, PCMs are classified as latent heat storage (LHS) units.
Latent heat storage can be achieved through liquid→solid, solid→liquid, solid→gas and liquid→gas phase changes. However, only solid→liquid and liquid→solid phase changes are practical for PCMs. Although liquid–gas transitions have a higher heat of transformation than solid–liquid transitions, liquid→gas phase changes are impractical for thermal storage because large volumes or high pressures are required to store the materials in their gas phase. Solid–solid phase changes are typically very slow and have a relatively low heat of transformation.
Organic PCM
Bio-Based, or Paraffin (CnH2n+2), or carbohydrate and lipid derived.
· Advantages
o Freeze without much undercooling
o Ability to melt congruently
o Self nucleating properties
o Compatibility with conventional material of construction
· Disadvantages
o Low thermal conductivity in their solid state. High heat transfer rates are required during the freezing cycle. Nano composites were found to yield an effective thermal conductivity increase up to 216%.
Inorganic
Salt hydrates (MnH2O)
· Advantages
o High volumetric latent heat storage capacity
o Availability and low cost
o Sharp melting point
· Disadvantages
o Incongruous melting and phase separation upon cycling which can cause a significant loss in latent heat enthalpy.
