Abstract
A stacking-type, multi-flow, heat exchanger includes a plurality of heat transfer tubes and fins stacked alternately, and a pair of tanks provided at either end of the heat transfer tubes. One of the tanks has an inlet tank portion and an outlet tank portion for the introduction and the discharge of a heat exchange medium to the heat exchanger. The heat exchanger has a flange member connected to the one of the tanks, the flange member has a flange body, an inlet pipe communicating with the inlet tank portion and an outlet pipe communicating with the outlet tank portion, and at least one of the inlet and outlet pipes is formed separately from the flange body. A passage for introducing heat exchange medium from the inlet pipe to the inlet tank portion and a passage for discharging heat exchange medium from the outlet tank portion to the outlet pipe are arranged in a thickness direction of the heat exchanger in parallel to each other. In this structure, the heat exchanger may be made to be thinner, smaller, and lighter than known heat exchangers.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
