Abstract
A parallel flow heat exchanger has perforated webs within its tubes. The tubes are parallel to each other and extend between headers. Each tube has webs located within it which define flow passages. The webs are perforated along the length to communicate refrigerant flow in one passage with that of refrigerant flow in other passages. The flow tubes are extruded integrally. The perforations are formed by air jets mounted in the extrusion die cores.
