Description

Technical Field

[0001] The utility model relates to a compact evaporator core structure, belonging to the technical field of evaporators. Background Art

[0002] As people's demands for car comfort increase, car air conditioning has become a must-have feature. At the same time, as vehicles incorporate more and more functions, the space occupied by air conditioning is gradually shrinking. This places higher demands on the overall spatial layout of air conditioning.

[0003] As the core component of the air conditioner, the air conditioner evaporator occupies a considerable part of the air conditioner's space. Most of the existing evaporator piping is welded from the side of the evaporator perpendicular to the evaporator body, which takes up more space. Utility Model Content
