SECO/WARWICK, an international leader in CAB technology, has signed a contract for the delivery of a continuous line for protective atmosphere brazing intended for the production of electric vehicle battery coolers. This is the first order from this Chinese customer.
Battery cooler production without secrets
The EV/CAB line will help the Chinese Partner maintain a key position on the automotive heat exchanger component market. Heat exchangers are manufactured in highly specialized, continuous lines for protective atmosphere brazing, and SECO/WARWICK is one of the most important manufacturers in the industry.
“CAB continuous furnaces use a variable speed drive (to transport products) with a stainless-steel mesh conveyor belt. The controlled atmosphere brazing process heats the product to the brazing temperature, while maintaining a uniform product temperature in a protective nitrogen atmosphere devoid of oxygen. We have already sold several dozen such solutions on the Chinese market alone.
Societal awareness related to the need to care for the natural environment is growing globally, and consistent legal changes in this direction are causing the electromobility sector to grow. SECO/WARWICK has great hopes for a product line dedicated to the Battery Cooler segment,” says Piotr Skarbiński, Vice President of the Aluminum Process and CAB Business Segment in SECO/WARWICK.
Hybrid power source
The advantage of the line on order is the hybrid gas-electric heating method, which ensures high energy savings thanks to heat recovery. SECO/WARWICK CAB lines guarantee efficiency, production repeatability and operational reliability.
The CAB line ordered by the Partner consists of a 1.6 m wide furnace TTBB chamber, radiation preheating chamber, radiation brazing furnace, cooling chamber with air jacket, final cooling chamber and control system. The furnace is fully electric; however, at the customer’s request, space was provided for the installation of gas-powered heating, which provides the flexibility for future savings.
The radiation CAB furnaces are an excellent solution for continuous brazing of products with similar dimensions and features. The temperature is distributed evenly over the entire length of the belt thanks to several independent heating zones. This type of equipment is characterized by lower investment costs and high efficiency that is achieved thanks to low nitrogen atmosphere consumption and lower service requirements compared to other CAB solutions. The CAB lines will be used for brazing large-sized car battery coolers.
“SECO/WARWICK has an excellent reputation on the Asian market. We supply CAB lines to many leading heat exchanger manufacturers. Our partners were convinced by the custom feature that will allow them to utilize the solution’s hybrid operation – gas-electric — that in turn allows for production flexibility and cost control. The partners also value the SECO/WARWICK equipment’s reliability and professional after-sales service,” said Liu Yedong, Managing Director of SECO/WARWICK China.
SECO/WARWICK – the automotive industry partner
This new Partner has production plants in Singapore, Malaysia, Thailand, Germany, the USA and China. The company is mainly involved in research, development and production of precision metal parts for the automotive, computer and telecommunications industries. This is another recognized SECO/WARWICK partner in Asia.
