Abstract
A heat exchanger includes a first tank and a second tank, an inlet and an outlet each connected to either the first tank or the second tank, and a plurality of panel units provided between and connected to the first and second tanks. Each of the panel units has a plurality of tube portions formed as fluid paths and a plurality of plate portions connecting adjacent tube portions and having a thickness less than a thickness of the tube portions. The heat exchanger is lightweight, can be easily assembled and can have a high efficiency in heat exchange.
Claims4
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.
