ABSTRACT:
A heat exchanger includes reservoirs spaced apart from each other and a plurality of parallel heat transfer tubes fluidly connecting the reservoirs. An end portion of each heat transfer tube is connected to at least one of the reservoirs so that the end portion does not project into the interior of the reservoir. Thus, the dimension of the reservoir in the axial direction of the tubes and a proper volume of heat transfer medium may be minimized. Further, pressure loss can be reduced because there are no projecting tubes in the reservoirs to obstruct the flow of the heat transfer medium. Moreover, the strength of the connection between the tubes and the reservoirs can be increased because more contacting surface area is provided for making the connection, for example by brazing.
