Abstract: The present invention relates to a heat exchanger for seawater of a cross counter flow to which electrophoretic painting is applied. The heat exchanger, in detail, is formed in a structure in which high temperature water and low temperature water are layered by using a square pipe. The heat exchanger has the same width, length, and height to be a regular hexahedron so that the electrophoretic painting is exposed by the force of gravity in a short time on the all surfaces of the heat exchanger. The heat exchanger also filters various contaminants contained in the seawater as a net type mesh is mounted on the inside of a U-bender of the heat exchanger. The growth of the contaminants attached to the inside of the heat exchanger is suppressed, and intrinsic functions of the heat exchanger are maintained. The heat exchanger is designed to be conveniently assembled or disassembled by being connected with a bolt in order to be conveniently maintained. The heat exchanger for the seawater of the cross counter flow maintaining a horizontal width and a vertical width to be the same increases a heat exchange area by using a square pipe and includes an inner hole capable of controlling an internal pressure and a flow rate of the heat exchanger by forming an inner connection hole in order to evenly exchange the heat by minimizing the pressure difference and the flow rate difference in each pipe. A plurality of square pipes is arranged in a header of the heat exchanger so that a fluid amount flowing in the pipe becomes different according to a position of the header of the heat exchanger. To solve this problem, the present invention is characterized in that the drawn fluid amount is maintained by changing the internal pressure of the header as the drawn part of the header becomes large, and the end becomes narrow.
