在用于传递的热交换器的要被冷却或加热的流体，特别是Heizeinrichung汽车空调系统的冷却剂被冷却的流体，包括至少一个管，特别是扁平管，用于使流体，至少一个收集区（5），其中，与所述至少一个管 被连接到所述至少一个Sammeibereich（5）以流体传导，形成在该至少一个采集区域的凸起（5）的入口具有Einlassaches到Anschlieeßen的进料管线（8）中的流体，形成于至少一个收集区的突起（5）出口喷嘴（10） （12）具有用于连接的流体，其中在所述热交换器的一侧形成有入口端口（10）和所述出口（12）的排出管线（9）的出口轴，所述热交换器在温度调节流体的横向方向，特别是空气， 用于冷却或流体，尤其是Kuhl 液体，可以流动，并且其中，在第一收集区域（6）的一个端部的换热器识别第一收集区水平和第一收集区域平面定向成平行于横向方向是不同的换热器（1）可与小的变化可以容易地和廉价地制造。 该目的是这样实现的进气口（10）由一个Einlassadapteistückes（23A）与收集区的装置（5，6）被连接和/或所述出口（12）借助于一个Auslassadapterstückes（23B）到所述收集区域（5，6） 已连接。

with the case of a heat exchanger for passing a to be cooled or heated fluid, in particular Heizeinrichung an automotive air conditioning system with cooling liquid as a fluid to be cooled, comprising at least one tube, in particular flat tube, for passing the fluid, at least one collecting area (5), wherein the at least one tube is the at least one Sammeibereich (5) in fluid communication, a formed on the at least one collecting area (5) inlet nozzle (10) with a Einlassaches to Anschlieeßen a supply line (8) for the fluid, a formed on the at least one collecting area (5) outlet (12) with an outlet axis for connecting a discharge line (9) for the fluid, wherein the inlet port (10) and the outlet (12) are formed on one side of the heat exchanger, said heat exchanger in a transverse direction of a tempering fluid, in particular air, for cooling or the fluid, in particular of the cooling liquid, can flow and in which the heat exchanger identifies a first collection area level at one end of a first collection region (6) and the first collection area plane is oriented parallel to the transverse direction to different heat exchanger (1) simple and inexpensive with low changes may be made. This object is achieved in that the inlet connection piece (10) by means of a Einlassadapteistückes (23a) is connected to the collecting area (5, 6) and / or the outlet (12) by means of a Auslassadapterstückes (23b) to the collecting area (5, 6) connected.
