HOW DOES A VACUUM INSULATED BOTLE FLASK REDUCE HEAT LOSS
How does a vacuum insulated botle flask reduce heat loss?
A vacuum insulated bottle flask which known Thermos Flask, Vacuum Flask, Vacuum Bottle, are usually made with double wall stainless steel materials, with a vacuum layer between the double wall to keeps liquid hot or cold long time.
In order to Maximize the heat retention performance, we want to know How does a vacuum insulated botle flask reduce heat loss?
Materials:
Material “stainless steel” won’t affect the heat loss or very little which we can ignore it, the materials only has different cost between different stainless steel becuause their anti-rust grade and food contact grade, such as SUS316, SUS304, SUS201.
Copper lining on inner wall:
copper lining on inner wall can surely improve the heat retention performance 10~15% based on tests on different designs/different sizes of stainless steel vacuum insulated bottle flasks;
Under same test enviroment, with same temperature hot or cold water, bottle with copper lining & bottle without copper lining, measure the temperature from begining, and 1hour, 2hours, 4hours, 6hours, 12hours, 24hours, the heat retention performance has 10~15% difference.
Bottle Mouth Size:
We need to try design smaller bottle mouth to reduce heat loss, because the main area where heat loss is the bottle mouth, it means the bigger mouth will more heat.
Bottle CAP/Lid:
We need to design the bottle cap/lid to have double wall as what the double wall stainless steel bottle body is, and can add a polyfoam inside the double wall cap, it can help to reduce the heat loss from the cap.
Gaskt location:
The gasket location and desing on the bottle cap, also will affect the heat loss of vacuum insulated bottle, we should design the gasket to seal water leaking inside of the bottle not seal water leaking on the top of the bottle mouth.
How does a vacuum insulated botle flask reduce heat loss?
Now we have the answers for this question;
- Designs (bottle mouth, cap, gasket)
- Copper lining
