Description

Modular profile structure car air conditioner

Technical field

The invention relates to an air conditioning system, in particular to a multi-functional modular profile structure vehicle air conditioner, which is widely used in passenger cars, motor homes, trucks, box trucks and trains, and can be determined according to the length of the vehicle. Length size.

Background technique

The existing automotive air-conditioning housing and air duct are mostly made of metal, injection molding material or FRP, which not only has high production cost, but also has poor thermal insulation performance of the housing, and its own quality is too heavy. When installed on the roof, it requires high local force and daily maintenance. inconvenient. Moreover, the length of the air conditioner cannot be adjusted as required for the required air outlet, cooling capacity and length of the roof platform. The air-conditioning fan has a long air supply distance and uneven air supply before and after, and since the existing air-conditioning housing structure has only a small fresh air inlet, it is not possible to ventilate a large amount of ventilation inside the vehicle. Existing car air conditioners need to be provided with larger air ducts, which will reduce the effective space height in the car. In addition, various functional devices arranged inside the air-conditioning structure must have separate casings, resulting in waste of materials. The versatility of manufacturing molds in the manufacture of different housings is inflexible, resulting in excessively high cost of manufacturing molds.

In addition, the existing automotive air conditioning structure does not have an add-on function module position that reserves water evaporative cooling and ventilation cooling. Other cooling methods cannot be selected depending on the region and climate. There is no humidification function when the air in the car is dry. It is not possible to disinfect the air conditioning ducts and the inside of the casing before and after use, which may be detrimental to human health for a long time.

Although there are some car water evaporative air conditioners, the main water tank directly participates in the semi-open water evaporation water supply, which makes the circulating water easy to deteriorate. And it is mainly composed of water storage tank, water supply device, water level detecting device, circulating water pump, circulating water tank, humidifying medium, water distribution device and related pipelines. Therefore, in order to achieve the effect of water evaporation and cooling, it is necessary to humidify the humidifying medium by using a large flow water distribution method. . In addition, many of its internal related components are not integrated, and the water level detection and control devices are not perfect.

In addition to the above problems, most of the existing air conditioner compressors are open type compressors, and the device is located near the engine. The distance between the compressor and the top air conditioner housing is too long, the maintenance surface is large, and the drawbacks are many. The method of draining condensate from conventional air conditioner evaporators also has an impact on the environment. When using the heating function, the heat of most heating devices comes from the engine and is transmitted through the coolant. However, similar to the cooling situation, for example, less heat will be obtained when the engine is idling. In addition, the existing air conditioner cannot perform local cooling when there are few passengers in the vehicle, which is not conducive to energy saving. In the event of a failure, the entire air conditioner will not work, so in this case it is best to have emergency response capabilities. In addition, due to the wide variety of passenger vehicles, it is bound to Description

1 and 4: The flap mechanism 23 is composed of a flap 75 with a heat insulating layer 74, a flap support plate 54, a flap lower support plate 55, a rotating device 76, and a rotary shaft 77. 75 is fixed to the flap support plate 54 and the lower flap support plate 55 which are disposed at intervals, and can be turned over along the rotary shaft 77 by the rotating device 76 provided thereon.

The sealing strip is attached to the "T" groove of the lower left cover and the right lower cover by bonding or snapping, and the flap 75 is coaxially coupled with the support plate 54 of the flap.

When the flap rotation device is configured as a quarter-turn motor, its rotary shaft is coaxially engaged with the round hole of the flap and is screwed to the support plate of the flap or the lower support plate of the flap. When the flap rotation device is configured to manually pull the wire, the movable portion of one end of the wire is pulled Description

(The core of the wire) is coupled to the flap, and the fixing portion is fixed to the support plate of the flap or the lower support plate of the flap. The other end of the cable is placed above the dashboard of the car or where the driver can operate.

As shown in Fig. 4 and Fig. 9, the initial angle of the flap 75 is approximately 29 from the horizontal positive direction. At this time, the left lower cover 44 and the right upper cover 38 can be sealingly fitted and the space can be divided into two parts, and the air inlet 56 and the air outlet 58 and the intermediate portion thereof constitute an air flow passage.

When the initial angle of the flap 75 is about 152° from the horizontal positive direction, it can be tightly fitted with the upper left cover 37 and the lower right cover 43 and divide the space into two parts. At this time, the air inlet 56 and the air supply port 57 and the middle portion thereof constitute an air flow passage, and the air return port 59 and the air outlet port 58 and an intermediate portion thereof constitute an air flow passage.

When the air inlet is located above the air conditioner, rainwater can also flow in while entering the air, in order not to affect the normal operation of the air conditioner. Therefore, it is necessary to have a rainwater discharge section.

There are two ways to do this:

When the initial angle of the flap 75 is about 152° from the horizontal positive direction, if rainwater flows to the flap surface through the air inlet 56, it is affected by gravity and then flows into the water collecting chamber 65 of the right lower cover 43 of the profile. It is discharged to the outside of the air conditioner by draining water 66 and check valve 67.

When the initial angle of the flap 75 is about 29° from the horizontal positive direction, if rainwater flows through the air inlet 56 to the surface of the flap 75, it is affected by gravity and then flows into the sump 64 of the lower lower cover 44.

The user can choose to install an engine-driven compressor, or an electric-driven compressor to achieve a mechanical cooling mode. Alternatively, multiple independent cooling modules can be installed in one housing for local cooling, and when one When the cooling module fails, other cooling modules can work, which greatly improves the system's ability to cope with accidents.

The invention can realize a plurality of working modes, and the specific working principle thereof is as follows:

As shown in Fig. 10: When the flap is in the closed position, that is, the flap 75 is about 29° from the horizontal positive direction, the humidifying medium does not work, and is in the mechanical cooling mode. At this time, the air in the vehicle compartment enters from the air return port 59, is induced by the air blowing fan 2, passes through the evaporator 8, and the air is cooled and finally delivered to the vehicle interior. The direction of air flow is shown by the arrow in Figure 9. In this mechanical cooling mode, the indoor air is circulated only between the interior of the vehicle and the air conditioning module, while the outdoor air flows only between the outside of the vehicle and the air conditioning module, and the two do not interfere with each other. This mechanical cooling mode is suitable for situations where the vehicle has a large cold load.

Figure 4: When the flap 75 is in the semi-closed position, the flap 75 is about 26° from the horizontal positive direction (the flap 75) Instruction manual

When rotating clockwise by 3°), the humidifying medium does not work, and there is a fresh air entering mode for mechanical cooling. At this time, fresh air enters from the air inlet 56, passes through the condenser 6, and is induced to be discharged into the vehicle compartment by the air blowing fan 2. The air in the vehicle compartment enters from the return air inlet 59, is induced by the air supply fan 2, passes through the evaporator 8, and the air is cooled and finally delivered to the vehicle interior. The direction of air flow is shown by the arrow in Figure 10. This kind of mechanical cooling has a working mode of fresh air entering, which is suitable for the case where the vehicle has a large cold load and needs fresh air.

When the flap 75 is in the fully open position, that is, the flap 75 is about 152° from the horizontal positive direction, the evaporator 8 and the condenser 6 and the humidifying medium are not operated, and the air cooling mode is adopted. The fresh air enters the vehicle compartment from the air inlet 56, and is induced by the air blowing fan 2, and then directly enters the vehicle interior, and the air in the vehicle interior is induced to be discharged outside the vehicle by the exhaust fan 3. The direction of air flow is shown by the arrow in Figure 4. This mode of ventilation cooling saves energy and improves air quality in the cabin while cooling.

It is shown in Fig. 10: When the flap 75 is in the closed position, that is, when the flap 75 is about 29° from the horizontal positive direction, the evaporator 8 and the condenser 6 and the humidifying medium do not work, and the ventilation is cooled in the inner circulation mode. At this time, the air in the vehicle interior flows in from the air return port 59, and after being induced by the air blowing fan 2, the air returns to the vehicle interior. The direction of air flow is shown by the arrow in Figure 9. This mode of ventilation and internal circulation can save energy while blocking outside noise.

When the flap 75 is in the fully open position, that is, the flap 75 is about 152° from the horizontal positive direction, the evaporator 8 and the condenser 6 and the humidifying medium are not operated, and only the air blower working mode is provided for the ventilation to cool down. At this time, the fresh air enters the vehicle interior from the air inlet 56, and is induced by the air blowing fan 2, and directly enters the vehicle interior. It is naturally discharged through the return air port 59. The direction of air flow is shown by the arrow in Figure 10. This type of ventilation cooling can only save energy while improving the indoor air quality.

When the flap 75 is in the full position, that is, the flap 75 is about 152° from the horizontal positive direction, the evaporator 8 and the condenser 6 are not operated, and the humidifying medium 18 operates as a water evaporation cooling mode. At this time, fresh air enters from the air inlet 56, and after flowing through the humidifying medium 18, it is cooled and humidified, and then sent to the vehicle interior by the air blowing fan 2 through the air blowing port 57. The return air in the interior of the vehicle is induced by the exhaust fan 3, enters through the return air port 59 and flows through the condenser 6, and finally exits from the exhaust vent 58 to the outside of the vehicle. The direction of air flow is shown by the arrow in Figure 4. This water evaporative cooling mode is suitable for situations where the cold load in the vehicle interior is small and the air is dry.

As shown in Fig. 4: When the flap 75 is in the closed position, that is, the flap 75 is about 29° from the horizontal positive direction, the evaporator 8 and the condenser 6 are not working, and the humidifying medium 18 is operated, which is the water evaporation inner circulation cooling mode. . At this time, the air in the vehicle interior flows in from the air return port 59, passes through the humidifying medium 18, and is cooled and humidified, and then induced by the air blowing fan 2, and then sent to the vehicle interior by the air blowing fan 2 through the air blowing port 57. The direction of air flow is shown by the arrow in Figure 4. This water evaporation a manual
