Abstract
The present invention relates to a novel brazed rectangular channel plate heat exchanger, comprising an outer shell, a heat exchange main body, and two inlet and outlet liquid interface components; the inner fins of the heat exchange unit of the heat exchange main body respectively form odd-numbered fluid channels and even-numbered fluid channels with the upper and lower walls of the rectangular flat tube; the upper fluid inlet and outlet ports I and II of the upper part of the rectangular flat tube are connected through the odd-numbered fluid channels, and the lower fluid inlet and outlet ports I and II of the lower part of the rectangular flat tube are connected through the even-numbered fluid channels; the first fluid inlet and outlet I interface of the first inlet and outlet liquid interface component is connected through the odd-numbered fluid channels of the odd-numbered heat exchange unit and the even-numbered fluid channels of the even-numbered heat exchange unit and the first fluid inlet and outlet II interface of the second inlet and outlet liquid interface component; the second fluid inlet and outlet I interface of the first inlet and outlet liquid interface component is connected through the odd-numbered fluid channels of the even-numbered heat exchange unit and the even-numbered fluid channels of the odd-numbered heat exchange unit and the second fluid inlet and outlet II interface of the second inlet and outlet liquid interface component. The heat exchanger has high heat exchange efficiency.
