Claims
- 1. A method for manufacturing a heat exchanger including a first tank and a second tank, an inlet and an outlet each connected to either said first tank or said second tank, and a plurality of unitary panel units provided between and connected to said first and second tanks, each of said unitary panel units comprising a plurality of metallic tube portions formed as fluid paths communicating between said first and second tanks, the method comprising the steps of:
- forming a plurality of unitary panel units having said plurality of metallic tube portions and a plurality of plate portions connecting adjacent metallic tube portions; and
- pressing said plate portions so that a thickness of said plate portions is less than a thickness of said metallic tube portions.
- 2. A method for manufacturing a heat exchanger including a first tank and a second tank, an inlet and an outlet each connected to either said first tank or said second tank, and a plurality of panel units provided between and connected to said first and second tanks, each of said panel units comprising a plurality of tube portions formed as fluid paths communicating between said first and second tanks, the method comprising the steps of:
- forming a plurality of units having said plurality of tube portions, a plurality of rod portions each disposed between adjacent tube portions and a plurality of plate portions connected between said tube portions and said rod portions; and
- pressing said rod portions and said plate portions so that a section of each of said rod portions and said plate portions connected to both ends of said each of said rod portions is formed in a thin plate portion and a thickness of said thin plate portion is less than a thickness of said tube portions.
- 3. The method of claim 1 further comprising the step of providing at least one louver on at least one of said plate portions of at least one of said panel units.
- 4. The method of claim 2 further comprising the step of providing at least one louver on at least one of said plate portions of at least one of said panel units.
