Embodiment Construction

[0041] Such as figure 1 , 3 As shown, an arrangement method of an automobile air conditioner includes the arrangement of an electric heater 1 and a warm air core 2. The method is to arrange the electric heater 1 and the warm air core 2 in the main air flow area, and placed perpendicular to the airflow direction P.

[0042] Also see figure 2 , in this specific embodiment, the layout of the electric heater 1 and the warm air core 2 conforms to the following geometric rules:

[0043] 1) The electric heater 1 and the warm air core 2 are both arranged in the main air flow area in the air conditioner box 3; usually the main air flow area is judged according to the results of the test measurement of the air flow rate inside the air conditioner, and the heat exchange element is placed as far as possible in the air flow area. in high areas;

[0044] 2) The dimensions of the warm air core 2 and the electric heater 1 conform to the following formula:

[0045] d 2 / d 1 ≥2 / 3; furth...

Abstract

The invention relates to a layout method of an automobile air conditioner, in particular to a layout method of an electric heater and a hot air core in the automobile air conditioner. The invention further relates to the automobile air conditioner manufactured according to the layout method thereof, and particularly relates to an automobile air conditioner in the field of new energy resources. The layout method of the automobile air conditioner includes layout of the electric heater and the hot air core, and is characterized in that both the electric heater and the hot air core are arranged in a main airflow area in an air conditioner box and are perpendicular to an airflow direction, sizes of the hot air core and the electric heater meet the formula: d2 / d2>=2 / 3, wherein d1 is the height of the cross section of the hot air core, and d2 is the height of the cross section of the electric heater. The air conditioner is manufactured according to the layout method. Technical problems that heat exchange efficiency of an electric heater and a hot air core of the prior art is low, and air volume loss of an air conditioner is high due to air pressure reduction are solved.

Description

technical field [0001] The invention relates to a method for arranging the internal structure of an air conditioner, in particular to a method for arranging an automobile air conditioner, in particular to a method for arranging an electric heater and a warm air core in an automobile air conditioner. The present invention also relates to the automobile air conditioner manufactured according to the arrangement method of the automobile air conditioner. Background technique [0002] Electric heater (PTC) and warm air core (water heating heater) are two kinds of heating components used in automotive air conditioners. Conventional car air conditioners usually only contain heater cores. The warm air core is an aluminum heat exchanger, which transfers the heat generated by the car engine to the air in the passenger compartment through the water-ethylene glycol solution as the medium. The disadvantage is that when the car is just started, the engine is still at normal temperature, ...
