What are the Different Types of Water Cooling Options for Vacuum Chambers?

March 17, 2020
 

Vacuum chambers are rigid enclosures where a low-pressure environment is created using gases and air. These chambers are widely used across industries for testing and production purposes. These systems produce a high amount of thermal energy, which if not handled properly may damage them. Although made of durable metals such as stainless steel, aluminum, hard steel or high-density ceramic, these systems feature integrated water cooling options. How do various cooling options help in thermal management? Read the post to know more

A Brief Introduction to Different Types of Integrated Cooling Options for Vacuum Chambers

The following are some popular types of integrated cooling options used for vacuum chambers

  1. Double Wall Chambers: Many applications produce high thermal heat loads, and double wall chambers are perfect for them. These chambers feature baffles that promote circulation as well as flow. Owing to their typical construction involving baffles, these double-wall chambers serve as one of the most effective types of cooling systems for vacuum chambers. Many jacketed vacuum chambers are fitted with double water-cooled walls which ensure efficient heat removal.
  2. Covered Channels (machined into a wall):Many custom vacuum chamber manufacturers will suggest you channels or water traces for applications involving low heat loads. These covered channels or water traces are directly machined into wall, and they provide cooling paths, thereby enabling a faster and efficient cooling for vacuum chambers.
  3. Welded ‘C’ Channels:These cooling options are suited for vacuum chambers, which produce low heat loads. As the name suggests, these channels are welded onto the surface of the chamber and they serve as cooling paths. These channels are accurately milled into the wall, and they help improve thermal transfer efficiently.
  4. Hydro-formed Channels:These channels offer almost 2x the surface area than welded C channels, and are considered a cost-effective heat transfer option. Unlike welded C channels, these hydro-formed channels feature radius bends, which helps regulate water flow, as well as avoid stagnant areas and low flow. Cooling channels are directly welded into the chamber, and open flow paths are created using water pressure. The channel edges are fully penetrated which helps minimize the risk of corrosion or cracks, and helps improve the working life of the vacuum chamber.

Although all these integrated cooling options serve the same purpose, they may not suit all vacuum chamber designs. The water cooling options are commonly used by vacuum chambers designed for vacuum deposition, space simulation, crystal growth, and vacuum furnaces. This is where an experienced custom vacuum chamber manufacturer like BEPeterson can help you. Being committed to deliver quality products, the company has been delivering jacketed vacuum chambers for several years now. All welding and assemblies adhere to the ASME Section VIII specifications
