Problems solved by technology
[0007] 1. The precision of the flat tube bending process is not high, which may easily cause local deformation of the condenser, damage the structure of the nearby fins, and reduce the heat transfer efficiency;
[0008] 2. The bent part of the flat tube has almost no heat exchange capacity, but the space structure is large in size and occupies a large installation space, making the heat exchange efficiency of the condenser low;
[0009] 3. The bending of the flat tube will cause the shape and size of the condenser to be unable to be accurately controlled, resulting in difficulty in installation

Embodiment Construction
[0030] Please refer to figure 1 As shown, the present invention discloses a heat exchanger 100 (condenser in this embodiment), which includes an inlet pipe 1, an outlet pipe 2, several first flow pipes 3 connected to the inlet pipe 1, and Several second flow pipes 4 connected to the outlet pipe 2, several heat dissipation fins 5 between two adjacent first flow pipes 3 and two adjacent second flow pipes 4, and sockets on the same layer Several flow pipe joints 6 on the first flow pipe 3 and the second flow pipe 4.
[0031] The inlet pipe 1 and the outlet pipe 2 are parallel to each other and located on one side of the heat exchanger 100 , and the flow pipe joint 6 is located on the other side of the heat exchanger 100 . In this embodiment, the first flow tube 3 and the second flow tube 4 are microchannel flat tubes arranged in several layers. The first flow pipe 3 and the second flow pipe 4 located on the same floor are connected by a flow pipe joint 6 . In the illustrated e...

The invention provides a circulating pipe joint and a heat exchanger with the same. The circulating pipe joint comprises a first sheet bar and a second sheet bar matched with the first sheet bar, the first sheet bar is provided with a first groove and a second groove, and the second sheet bar is provided with a third groove and a fourth groove. The first sheet bar and the second sheet bar are fixed together, the first groove and the third groove correspond to each other to together form a first storage channel used for being connected with a circulating pipe, and the second groove and the fourth groove correspond to each other and together form a second storage channel used for being connected with the circulating pipe. The circulating pipe joint is further provided with a separation part which is used for separating the first storage channel and the second storage channel. The circulating pipe joint and the heat exchanger with the same have the advantages that the circulating pipe joint can be machined easily; in addition, the circulating pipe joint is connected to the circulating pipe in a sleeved mode, the fact that the circulating pipe is directly bent is avoided, and the whole machining difficulty of the heat exchanger is lowered.
Description
technical field [0001] The invention relates to a flow pipe joint and a heat exchanger with the flow pipe joint, belonging to the field of automobile air-conditioning heat exchangers. Background technique [0002] In recent decades, automotive air conditioners have developed rapidly, accounting for the second place in air conditioning machinery. As one of the four main components of automotive air conditioning, the heat exchanger also needs to be improved and optimized according to market requirements. Because the parallel flow heat exchanger has the characteristics of high cooling efficiency, small size, light weight, etc., it can well meet the requirements of the market, and has been gradually used in automotive air-conditioning systems in recent years. [0003] As a form of heat exchanger, a parallel flow condenser mainly includes microchannel flat tubes, cooling fins and headers. There are headers at both ends of the microchannel flat tubes for distributing and collect...
