Description

Technical Field

[0001] The invention relates to the technical field of condensers, in particular to a collecting pipe mechanism of an automobile air-conditioning condenser. Background Art

[0002] The condenser is a component of the refrigeration system and a type of heat exchanger. It can convert gas or steam into liquid and quickly transfer the heat in the tube to the air near the tube. The working process of the condenser is a heat release process. The condenser has a wide range of uses and is also used in car air conditioners. The condenser includes a manifold mechanism, which is an important component for converting gas into liquid.

[0003] In the existing condenser, the refrigerant flows directly into the circular header from the inlet, and then directly into the flat tubes. When the refrigerant flows into the circular header of the condenser, it concentrates on flowing into the flat tubes close to the inlet. Therefore, more refrigerant flows through the flat tubes close to the inlet, and less refrigerant flows through the flat tubes far from the inlet. As a result, the refrigerant cannot pass through the flat tubes evenly, resulting in low utilization of the flat tube channels, and thus low utilization of the heat exchange area at the inlet of the condenser.
