The plate heat exchanger is a device for heat exchange between two media. We all know that there are four plate heat exchanger connections. The inlet and outlet of the heat medium and the inlet and outlet of the cold medium. According to the position of the inlet and outlet flanges, there are four types: single side, single side, double flow, and single side.
(1) Single side: It is a kind of standard type which is commonly used in plate heat exchangers. It is usually used for water, water and steam exchange; the four holes of the interface are on a plane of the fixed plate.The positioning dimensions are distributed over the four corners according to the regulations.
(2) Single side: The interface form determined according to the position of the pipe. The position of the interface is vertical on the left and right sides respectively.
(3) Double passes: usually used for heat transfer oil. Because of the high density and high concentration of oil, the heat transfer coefficient is low. Therefore, a baffle is installed in the middle to form two processes. The heat exchange coefficient is increased to complete the heat exchange, and the position of the flange is opposite on the upper sides of the left and right ends.
(4) Single side: It means that the four flange holes are on the left and right sides, respectively at the upper end of the left side and the lower end of the right side.
