Technical Field

[0001] The utility model belongs to the technical field of condensers, and relates to a double-flow condenser with an external liquid storage tank. Background Art

[0002] A condenser is a component of a refrigeration system and belongs to a type of heat exchanger. It can be used in automobiles for heat dissipation and refrigeration. Currently, a vehicle refrigeration system includes an oil cooler and a condenser, which are generally installed on the front-end cooling module of an automobile as two separate components. The oil cooler is an oil cooling device commonly used in hydraulic systems and lubrication systems.
