Energy
At ChemTecUSA, we help build the power systems of the future. Our metal components, including essential cooling plates, are at work in clean energy technologies, from hydrogen fuel cells to the latest electric vehicles. We know these systems need parts that are made well, perform under pressure and contribute to overall energy efficiency. Our expertise in chemical etching delivers the exact components needed for these demanding jobs, such as battery cooling plates, fuel cell bipolar plates and solar busbars.
Cooling Plates for Battery Thermal Management
As electric vehicle batteries charge and discharge, they generate heat. This heat must be managed to keep the battery safe, maintain its range and extend its useful life. This is the job of the thermal management system, often built around metal cooling plates. These plates are typically thin, flat pieces of metal with an internal maze of channels. A coolant fluid flows through these channels, absorbing heat from the battery cells.
The design of these channels directly affects how well and how evenly the battery is cooled. Using chemical etching, we can create these complex internal channel patterns directly into the plate. There are no seams or welds that could leak. The channels can be designed to direct coolant flow exactly where it is needed most, pulling heat away from the battery pack effectively. A well-made cooling plate supports stable battery performance and consistent vehicle range. See our material expertise page for more on our capabilities with metal components.
Chemical Etching
Creating parts for the energy sector presents a distinct set of challenges. Materials are often thin and difficult to shape without stress or burrs. Designs require detailed channels and patterns, particularly for parts like bipolar plates and liquid-cooled cooling plates. Traditional methods like stamping or laser cutting can leave behind imperfections that affect performance. Chemical etching is different.
Our etching process uses a chemical solution to pierce metal. It does not use heat or force, so there is no risk of warping the material or changing its internal properties. This means we can work with delicate, thin metals like stainless steel, copper or brass exactly as they come from the mill. We can etch intricate and detailed patterns like the tiny, complex channels in a fuel cell plate or a battery cooling plate with a high level of dimensional control. The result is a clean and burr-free part ready for assembly.
Fuel Cell Bipolar Plates
Hydrogen fuel cells are a leading technology for zero-emission power. The bipolar plate is the heart of the fuel cell stack. It performs three jobs at once: it distributes hydrogen and oxygen gases, conducts electricity between cells and removes water and heat from the system, a function that often integrates with separate cooling plates in the stack.
These plates must be electrically conductive, highly resistant to corrosion from the fuel cell environment and lightweight. They also contain a dense network of fine channels for gas and coolant flow. Stamping these channels can be tough, especially with very thin or brittle materials. Our chemical etching process creates these perfect channels without stressing the metal. The process allows for clean, consistent channel walls that promote uniform gas flow and strong electrical contact across the entire plate surface. This supports strong electrical output and consistent fuel cell operation.
Energy Busbars
Efficiency is everything regarding solar panels. Busbars are the thin, conductive energy systems that collect and move the electricity. To keep systems efficient, these busbars need to be as narrow for space constraints, while still carrying significant electrical current. While distinct from cooling plates, they share the need for precision manufacturing.
They also need to have a very specific surface profile to bond well with the cell’s solder. Chemical etching is a superior method for creating these precise parts. We can produce ultra-thin, consistent busbars with the exact shape needed for a strong and low-resistance connection. This helps reduce power loss within the system and allows more energy to move efficiently to its intended destination.
