technical field

The invention relates to the field of automobile air conditioners, in particular to an air conditioner layout structure for automobiles and an automobile using the same.

Background technique

The four major components of the air-conditioning system are the compressor, the evaporator, the condenser and the electronic expansion valve. During the refrigeration operation, the low-temperature and low-pressure refrigerant evaporates in the evaporator and becomes a low-temperature, low-pressure superheated gas; The gas pipe enters the compressor, and the gas compressed into high temperature and high pressure enters the condenser, where it is condensed into high pressure subcooled liquid by releasing heat to the ambient air. After being throttled and expanded by the electronic expansion valve, it becomes a low-temperature and low-pressure gas-liquid mixed refrigerant, which enters the evaporator, absorbs heat from the air flowing through the evaporator and evaporates, and reduces the temperature of the air passing through the evaporator to achieve the purpose of refrigeration. The evaporated refrigerant vapor is sucked into the compressor again to start the next refrigeration cycle. At the same time, the cooled air is sent to the various areas in the car that need to be cooled by the blower.

Arrangement to improve the comfort of the vehicle.

Optionally, the partition 105 that separates the evaporation chamber into the upper and lower layers is a sheet metal part. When the sheet metal part is used for partitioning, since the sheet metal part can be made into a multi-bending shape, the air guiding effect can be enhanced. In addition, the open-die sheet metal parts can also be used directly, and the air guiding effect is better.

In some optional implementations, the air conditioner layout structure further includes: a condensation chamber located below the evaporation chamber, a condensation fan disposed on the first side wall 202 of the condensation chamber, and a second side wall surrounding the condensation chamber 203 and/or the condenser inside the third side wall 204 and/or the fourth side wall 205. Correspondingly, when two evaporating chambers are used, two condensing chambers are also used, that is, a first condensing chamber 201a and a second condensing chamber 201b are provided, wherein the first condensing chamber 201a is located under the first evaporating chamber 101a, and the second condensing chamber 201a is located below the first evaporating chamber 101a. The chamber 201b is located below the second evaporation chamber 101b.

Correspondingly, there are also two condensers, including a first condenser 209a and a second condenser 209b. The first condenser 209a is surrounded on the second side wall and the third side wall of the first condensation chamber 201a.

The pipeline is arranged between the two axial flow fans, which can effectively utilize the space of the condensing cavity and maximize the heat exchange area of the condensing heat exchanger.

Further, the air-conditioning layout structure further includes the compressor and the pipeline component after the optimized arrangement position. The pipeline assembly is used for connecting the compressor, the condenser and the evaporator to form a switchable and selectable refrigerant circulation path, so as to cooperate with the cooling and heating mode of the air conditioner. Regarding its arrangement position, preferably, a pipeline cavity 207 is formed between the first condensation cavity 201a and the second condensation cavity 201b, and the compressor and the pipeline part assembly 206 are arranged in the pipeline cavity 207.

The invention improves the placement form of the heat exchanger and the air inlet and outlet forms of the internal and external fans: the evaporation chamber adopts the layout form of double return air and four air outlets, and divides the evaporation chamber into four parts: upper, lower, left, right, and each part. Evaporator, and then through the shared high inlet pressure fan (evaporation fan) to return air from the upper (upper return air outlet) and the front (side wall return air outlet) double return air outlet, after passing through the heat exchanger, it passes through four independent outlets. The air outlet is used for air supply, and the water receiving plate is located in the evaporation chamber away from the fan, that is, it is set at the end positions on both sides of the evaporation chamber. It can be drained by the fan, which is conducive to the collection and discharge of the condensed water of the evaporator; while reducing the thickness and increasing the heat exchange The area of the condenser can reduce the wind resistance, and at the same time, the air conditioning capacity and energy efficiency can be optimized; the evaporative fan adopts a high inlet pressure fan, which is placed in the middle of the two evaporators, and two axial fans are used on the condensing side.

After heat exchange through the four evaporators, it is blown out through the four air outlets corresponding to the upper part of the whole machine and the two sides, and then enters the car. The air duct is finally blown into the car through the corresponding air duct. It should be noted that, when the air conditioner realizes circulating air supply in the vehicle, the air in the vehicle returns to the evaporative fan through the return air duct on the inside of the vehicle communicated with the air return port 301; when the air conditioner realizes external circulation, the air return port 301 It can be connected to the fresh air duct, and the fresh air is sent from the outside. At this time, the return air duct inside the car is directly connected to the outside of the car, and the air in the car is discharged outside the car.
