The invention discloses a double-channel folding flat pipe. According to the double-channel folding flat pipe, two fluid channels are formed through a bending process, the structure is compact, and manufacturing is easy to carry out. The invention further provides a method for manufacturing the double-channel folding flat pipe.The high-strength aluminum alloy design is used in combination, the pipe wall is thinned, the weight of the flat pipe is reduced, and different aluminum alloy material strips can meet various application requirements. The double-channel folding flat pipe can be used for manufacturing a composite heat exchanger so as to achieve efficient heat exchange of at least two kinds of fluid. When the composite heat exchanger is used in a vehicle, the design of a heat exchange system needed by a vehicle air conditioning system and a power system can be simplified, more specifically, for a new energy vehicle, coupling between the air conditioning system and a battery cooling system is achieved, and the manufacturing cost of a vehicle thermal management system is reduced.

    本发明公开了一种双流道折叠扁管,该双流道折叠扁管通过弯折工艺形成两种流体通道,结构紧凑,制造简单。还提供了一种制造双流道折叠扁管的方法,结合高强度铝合金设计,实现了管壁减薄,降低了扁管重量,不同的铝合金材料带可满足各种应用需求。该双流道折叠扁管可用于制造复合换热器,以实现至少两种流体的高效换热,将该复合换热器用于车辆中,能够简化车辆空调系统和动力系统所需的换热系统设计,更具体地,对于新能源车辆来说,实现了空调系统与电池冷却系统的耦合,降低了车辆热管理系统的制造成本。
