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

Abstract

The invention discloses a header assembly and a heat exchanger. The manifold assembly includes a manifold and a swirl vane arranged in the manifold, the manifold has an opening for fluid to enter, and the swirl vane is arranged along the axial direction of the manifold extending helically and having a blocking surface extending radially of the header, the blocking surface facing the opening. In the above arrangement, a swirl sheet with a blocking surface is provided inside the header, so that the blocking surface of the swirl sheet can block part of the liquid from moving directly from one end of the header to the other end of the header due to inertia, The phenomenon of liquid accumulation at one end of the header is avoided, so that the gas-liquid two-phase distribution in the header is relatively uniform, and the heat exchange performance of the header assembly and the heat exchanger is improved.

Description

technical field [0001] The present application relates to the field of heat exchange, and in particular, to a header assembly and a heat exchanger. Background technique [0002] In the field of air conditioning, the application of microchannel heat exchangers is becoming more and more extensive. In the existing microchannel heat exchangers, the gas-liquid two-phase fluid directly enters the interior of the header through the opening opened in the header, and then Then enter the heat exchange tube. Such an approach is likely to cause uneven distribution of the gas-liquid two-phase fluid in the header. Specifically, the header usually has a first section close to the opening and a tail section away from the opening. The fluid enters the header through the opening, and the liquid easily flows directly to the tail section due to large inertia, causing the liquid to be concentrated and distributed in the header. Phenomenon of the tail section of the header. As a result, the ga...
