Automobile air conditioner

Abstract

An automobile air conditioner comprises at least two independent temperature areas, and a heating core is arranged in each independent temperature area. And the cooling liquid loop comprises a cooling liquid main path and at least two cooling liquid branches, the cooling liquid main path is communicated with the cooling liquid branches, and the cooling liquid branches are respectively connected with the heating core bodies in the independent temperature areas. The automobile air conditioner provided by the embodiment of the invention can realize independent temperature control of each independent temperature zone, and also has the advantages of simple structure, low cost, high safety and the like.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an automobile air conditioner. Background technique [0002] With the improvement of living standards, people's requirements for the comfort of automobile air conditioners are also further improved. Electric heaters and warm air cores are two common heating components used in automotive air conditioners. Traditional car air conditioners usually only include a heater core. The hot water provided by the engine exchanges heat with the air in the car through the heater core. However, the heat source provided by the engine is not adjustable. To increase the mixing area of ​​cold and warm air, adjust The ratio of cold air to warm air is used to adjust the temperature. If you want to adjust the temperature of multiple partitions, you need to add multiple cold and warm air mixing areas, resulting in a larger shape of the automotive air conditioner assembly and higher...

Problems solved by technology

Traditional car air conditioners usually only include a heater core. The hot water provided by the engine exchanges heat with the air in the car through the heater core. However, the heat source provided by the engine is not adjustable. To increase the mixing area of ​​cold and warm air, adjust The ratio of cold air to warm air is used to adjust the temperature. If you want to adjust the temperature of multiple partitions, you need to add multiple cold and warm air mixing areas, resulting in a larger shape of the automotive air conditioner assembly and higher requirements for layout space.

[0003] With the development of automobile technology, new energy vehicles have been widely used. New energy vehicles have canceled the fuel engine, so some models use electric heaters to replace the original engine-warm air core heating system, but the use of electric heaters Heating, there is a safety risk that high-voltage electricity directly enters the passenger compartment of the car, and the cost is high
