The air intake shell 1.3 adopts a two-half structure and is fixed by means of snaps and bolts. The air intake shell is provided with an internal air inlet 1.2, an external air inlet 1.1 and an air outlet. A partition 1.7 is provided in the air intake shell, and the outer end of the partition extends to the air outlet position, dividing the air outlet into an internal air outlet and an external air outlet. The two sides of the partition constitute the separated internal air intake main air duct and the external air intake main air duct. An opening is provided at the partition, and an internal and external air mixed intake damper that can realize the opening and closing of the partition is installed at the opening position. An external air intake damper which can be opened and closed is installed at the external air intake port, and an internal air intake damper is installed at the internal air intake port or in the internal air intake duct.

[0040] The filter core plate 1.8 is fixed to the outside of the air outlet of the air inlet housing, and is used to filter the output internal and external air. An internal air guide plate 1.9 is fixedly installed at one end of the filter core away from the air outlet of the air inlet housing, and is used to guide the internal air into the lower layer of the double laminar flow blower. The double laminar flow blower is installed on the side of the internal air guide plate away from the filter core plate, and its upper layer is used to realize the introduction of external air output from the air inlet housing, and discharge it through the air outlet of the upper layer, and its lower layer is used to realize the introduction of internal air output from the air inlet housing, and discharge it through the air outlet of the lower layer.

[0041] The air intake part can open and close the air door according to the needs to realize the separate intake of external air, the separate intake of internal air, and the simultaneous intake of external and internal air.

[0042] The internal and external air inlets of the air inlet housing can be configured as rectangular shapes, such as Figure 6 As shown, the shape can be changed as needed to change into a round shape ( Figure 7 ), oval( Figure 8 ), square and irregular shapes.

[0043] The heat exchange part is used to realize the heat exchange between the internal air and the external air. It mainly includes a heat exchange shell 2.1, a middle partition 2.3, an exhaust air duct 2.5, a full heat exchanger core 2.4 and a full heat exchanger air intake damper 2.2. The heat exchange shell adopts a two-half structure and is fixed by means of buckles and bolts. The middle partition is arranged inside the heat exchange shell and is fixed to the inner wall of the shell by a rib groove structure. The middle partition divides the inner cavity of the heat exchange shell into two upper and lower cavities. The upper chamber 2.7 is the heat exchange chamber, and the lower chamber 2.6 is the inner air chamber. One end of the heat exchange shell is the air inlet end, wherein the upper part of the middle partition constitutes the external air inlet and the lower part constitutes the internal air inlet; the other end of the heat exchange shell is the air outlet end, wherein the upper part of the middle partition constitutes the external air outlet and the lower part constitutes the internal air outlet. The air inlet end of the heat exchange shell is aligned with the air outlet end of the double-laminar flow blower, and the air inlet of the upper layer of the heat exchange shell is connected to the air outlet of the upper layer of the double-laminar flow blower, and the air inlet of the lower layer of the heat exchange shell is connected to the air outlet of the lower layer of the double-laminar flow blower, so that the external air flows into the heat exchange chamber and the internal air flows into the internal air chamber.

[0044] An opening is provided at the top of the ventilation chamber for discharging part of the internal air. The full heat exchanger core is provided in the heat exchange chamber, and its upper end extends to the top wall of the heat exchange shell and is aligned with the opening. The full heat exchanger core is fixed by the middle partition and the baffle on the inner wall of the heat exchange shell. A closed first space is formed between the side of the full heat exchanger core close to the external air inlet of the heat exchange shell and the external air inlet, forming an external air inlet buffer zone. A closed second space is formed between the bottom surface of the full heat exchanger core and the middle partition, forming an internal air input buffer zone for partial internal air input. An opening is provided on the middle partition at a position corresponding to the internal air input buffer zone, and a full heat exchanger air intake damper is installed at the opening for closing the opening and adjusting the size of the opening. Through the opening, part of the internal air can flow into the vertical flow channel in the full heat exchanger core to exchange heat with the external air passing through the transverse flow channel of the full heat exchanger core.

[0045] The exhaust duct is fixed on the top of the heat exchange shell, and is provided with an air inlet and an exhaust port. The air inlet corresponds to the opening on the top of the heat exchange shell, and the exhaust port is used to output the internal air after heat exchange. The exhaust direction is not limited, and the exhaust direction can be selected from the top, bottom, front, back and any angle. Figure 9-12 , the exhaust duct 2.5 exhaust hole shape can be circular, oval, rectangular or any irregular shape, such as Figure 6 , 7 , 8, 9. The total heat exchanger air intake damper 2.2 can be a butterfly damper ( Fig.13 )、Sliding damper( Fig.14 )、Fan-shaped damper( Fig.15 ) and plate damper ( Fig.16 ), the damper adjustment angle is 0-60°. According to the specific structure of the air intake damper of the total heat exchanger, it is connected to the middle partition or the shell walls on both sides of the heat exchange shell.

[0046] Each of the above-mentioned air doors is provided with a driving motor which is controlled by the air conditioning system, but is not shown in the accompanying drawings.

[0047] In the present invention, in order to simplify the structure, the heat exchange shell and the shell of the double laminar flow blower adopt an integrated structure, and the heat exchange shell can also be called a blower shell.

[0048] The warm air part is connected to the air outlet end of the heat exchange shell, and mainly heats and cools the internal and external air entering in layers, and adjusts the internal dampers to allow the internal and external air to enter the vehicle in the form of head blowing mode, foot blowing mode, defrost mode and defrost foot blowing mode.

[0049] The working principle of the present invention is:

[0050] The internal air and external air enter from the internal air inlet and external air inlet of the air intake housing respectively. After being filtered by the filter core plate, the internal air passes through the blower, and is blown out from the lower layer of the blower 1.1 and enters the internal air chamber located below the middle partition in the heat exchange housing. The internal air entering the internal air chamber is divided into two situations: 1. When the air intake damper of the total heat exchanger is closed, all the internal air enters the car. When the air intake damper of the total heat exchanger is opened, part of the internal air enters the car, and part passes through the core of the total heat exchanger to achieve heat exchange, and then is discharged out of the car through the exhaust air duct. In this way, the air inside the car cools the air outside the car in summer and heats the air outside the car in winter, achieving energy saving and environmental protection. At the same time, through the external air intake, the fresh air outside the car is introduced into the car, so that the air inside the car is purified, which increases the comfort of the driver and passengers.

[0051] Tests have shown that full heat exchanger car air conditioners have the obvious advantages of reducing energy loss and purifying the air inside the car. They can save 15% of energy in summer and 16% in winter. Fig.17 , 18 shown.

[0052] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
