Problems solved by technology
This method is likely to cause uneven distribution of gas-liquid two-phase fluid in the header
Specifically, the collecting pipe usually has a first section close to the opening and a tail section far away from the opening. The fluid enters the collecting pipe through the opening, wherein the liquid tends to flow directly to the tail section due to the large inertia, causing the liquid to be concentrated and distributed in the The phenomenon of the tail section of the header
The gas-liquid two-phase distribution in the fluid is uneven, which reduces the heat transfer performance of the heat exchanger

The invention discloses a collecting pipe assembly and a heat exchanger. The collecting pipe assembly comprises a collecting pipe and a flow swirling piece arranged in the collecting pipe, the collecting pipe is provided with an opening capable of allowing a fluid to enter, the flow swirling piece spirally extends in the axial direction of the collecting pipe and is provided with a blocking face extending in the radial direction of the collecting pipe, and the blocking face faces the opening. In the arrangement, the flow swirling piece with the blocking face is arranged in the collecting pipe,thus the blocking face of the flow swirling piece can block part of fluid from directly moving from one end of the collecting pipe to the other end of the collecting pipe due to inertia, the phenomenon of stacking of the fluid at one end of the collecting pipe is avoided, thus distribution of a gas phase and a liquid phase in the collecting pipe is relatively uniform, and the heat-exchanging property of the collecting pipe assembly and the heat exchanger is improved.
Description
technical field [0001] The application relates to the field of heat exchange, in particular to a header assembly and a heat exchanger. Background technique [0002] In the field of air conditioning, the application of micro-channel heat exchangers is becoming more and more extensive. In the existing micro-channel heat exchangers, the gas-liquid two-phase fluid directly enters the inside of the header through the opening in the header, and then Then enter the heat exchange tube. Such a method is likely to cause uneven distribution of the gas-liquid two-phase fluid in the header. Specifically, the collecting pipe usually has a first section close to the opening and a tail section far away from the opening. The fluid enters the collecting pipe through the opening, wherein the liquid tends to flow directly to the tail section due to the large inertia, causing the liquid to be concentrated and distributed in the The phenomenon of the tail section of the collector. As a result,...
