## Abstract

A method of manufacturing a plate heat exchanger. The method of manufacturing a plate heat exchanger includes the steps of: electroplating a surface of a mold having a groove pattern formed on a surface thereof to form a plate; separating the plate from the mold; electroplating both sides of the separated plate with a brazing binder to form a plate unit; stacking the plate units such that grooves formed on the plate units intersect each other; and heating and pressing the stacked plate units to bind them each other.

## Claims

### Claim 1

A method of manufacturing a plate heat exchanger, comprising the steps of:
electroplating a surface of a mold having a groove pattern formed on a surface thereof to form a plate;
separating the plate from the mold;
electroplating both sides of the separated plate with a brazing binder to form a plate unit;
stacking the plate units such that grooves formed on the plate units intersect each other; and
heating and pressing the stacked plate units to bind them each other.

### Claim 2

A method of manufacturing a plate heat exchanger, comprising the steps of:
electroplating a surface of a mold having a groove pattern formed on a surface thereof with a brazing binder;
electroplating a surface of the brazing binder to form a plate;
electroplating a surface of the plate with a brazing binder to form a plate unit;
separating the plate unit from the mold;
stacking the plate units such that grooves formed on the plate units intersect each other; and
heating and pressing the stacked plate units to bind them each other.
