BMW meets Audi

BMW meets Audi

Recently, BMW officially announced that it will expand its production capacity in China and double its engine production to reduce costs while at the same time narrowing the gap with Audi in sales and profits.

According to Bloomberg News, BMW plans to expand its production capacity at its plant in Shenyang in its partner, Brilliance China Automotive Holdings Co., Ltd. It is expected that the Shenyang plant's annual production will exceed 400,000 vehicles.

China officially overtook the United States as BMW's largest sales market in 2013. Last year, BMW's sales in China reached 391,713 vehicles, which accounted for 17% of its global sales. Last year, BMW sold 376,636 vehicles in the United States, far behind China.

In the first two months of this year, Audi sold more cars in China for the first time in nine years. Although it only exceeded 383 cars, Audi is also working hard to expand sales as Audi's largest market.

BMW's increase in engine and car production is undoubtedly beneficial to reducing costs and increasing profits, and it also shortens the time for replacement of new cars. In addition, BMW can also use this to reduce the exchange rate risks associated with international trade.

Twisted Tube Heat Exchanger

Twisted Tube Heat Exchanger is to strengthen the turbulence of the flowing gas/fluid, so that the gas and the tube wall contact thoroughly. In addition to enhancing heat transfer, the twisted tube heat exchanger also has the advantages of reducing scaling, self-supporting between tube bundles, no baffle plate elements and so on.


With that being said, novel Twisted Tube Heat Exchanger is much more efficient than conventional tubular heat exchanger, or Shell And Tube Heat Exchanger. Twisted tube heat exchangers are also used in applications where the fluids are corrosive or contain particulates, as they are better able to handle these conditions than other types of shell and tube heat exchangers or Air Heat Exchanger.


Twisted tube heat exchangers are constructed from a series of twisted tubes arranged around a central tube. The tubes are twisted in such a way that the fluid will change direction multiple times as it passes through the exchanger. This increases the turbulence of the fluid and creates a larger surface area for the heat exchange, which increases the efficiency of the exchanger.


The shell is usually made from a thick metal such as carbon steel, which increases the durability of the exchanger.
