[0002] With the rise of motor home tourism culture, motor homes have become the first choice for more and more people to travel. Of course, not only motor homes, with the upgrading and cost reduction of related technologies in the automobile manufacturing industry, vehicles are endowed with more functions in addition to transportation, such as temporary duty stations, blood donation stations, temporary aid stations, etc. Most of them are converted from vehicles. These vehicles, unlike conventional vehicles, need to ensure the normal operation of some functions on the vehicle after parking, such as air conditioning.
[0003] In the prior art, due to the limited space inside the vehicle, the space reserved for installing the air conditioner is small, and an air conditioner capable of hidden installation has appeared, that is, the evaporative side and the condensing side of the air conditioner are integrated in one box. Because the evaporative side and the condensing side of the air conditioner are integrated in one box, the air outlet of the air conditioner is affected, and the air cannot be evenly blown out, and the wind energy is lost during the blowing process, resulting in small air volume and large noise during blowing. In view of this, a direct air cooling system of air conditioner is needed to be designed to meet the requirements of uniform air blowing, sufficient air volume and quiet blowing. CONTENT OF THE UTILITY MODEL

[0060] With the rise of recreational vehicle tourism culture, recreational vehicles have become the first choice for more and more people to travel. Of course, not only recreational vehicles, but also vehicles are endowed with more functions such as temporary duty station, blood donation station, temporary rescue station and the like in addition to transportation, which are mostly modified from vehicles. These vehicles, which are different from conventional vehicles, need to ensure the normal operation of part of the functions on the vehicle after parking, such as air conditioning.
[0061] In the prior art, due to the limitation of the internal space of the vehicle, the place reserved for installing the air conditioner is small, and a hidden type air conditioner that can be installed is appeared, that is, the evaporating side and the condensing side of the air conditioner are integrated in one box. Due to the integration of the evaporating side and the condensing side of the air conditioner in one box, the air outlet of the air conditioner is affected, and the air cannot be evenly blown out, and the wind energy is lost during the blowing process, resulting in small air volume. In view of this, it is necessary to design a direct blowing type air conditioner heat exchange system and an air conditioner to meet the requirements of the user for the uniform air outlet of the vehicle air conditioner and the large air volume.
[0062] It needs to be understood that the so-called "evaporation side", "evaporator", "condensation side" and "condenser 9" in the utility model are all for the internal components of the air conditioner. According to the general calling habit, the part installed in the room or the part for temperature regulation and heat exchange of the room is called "evaporation side", and the part installed in the outdoor or the part for heat exchange with the outdoor air is called "condensation side". When the air conditioner works, in the cooling mode, the evaporator absorbs the indoor heat, and the condenser 9 releases heat to the outdoor air, and in the heating mode, the air conditioner changes the flow direction of the refrigerant through the internal four-way reversing valve, so that the functions of the evaporator and the condenser 9 are interchanged, but the installation positions of the evaporator and the condenser 9 cannot be interchanged, at this time, the evaporator located in the room releases heat to the room, and the condenser 9 located in the outdoor absorbs the outdoor heat.
[0063] As shown in Figure 1 , a schematic diagram of the external structure of an air conditioner is disclosed. As shown in Figure 2 , a schematic diagram of the internal structure of an air conditioner is disclosed, in Figure 2 , the internal structure of the air conditioner adopts a direct blowing type air conditioner heat exchange system comprising a flow equalizing cavity 10, Figure 2 , the direct blowing type air conditioner heat exchange system is installed on the evaporation side of the air conditioner, of course, according to the heat exchange principle of the air conditioner, the direct blowing type air conditioner heat exchange system can also be used on the condensation side of the air conditioner, or low-noise air conditioner heat exchange systems are used on the evaporation side and the condensation side of the air conditioner.
[0064] In order to facilitate the understanding of the structure and function of the direct blowing type air conditioner heat exchange system by those skilled in the art, the structure and function of the direct blowing type air conditioner heat exchange system when installed on the evaporation side will be described in detail below.
[0065] Embodiment one:
[0066] As shown in Figure 2 and 3 , in this embodiment, the direct blowing type air conditioner heat exchange system comprises: a first heat exchange cavity A, a first heat exchanger 6, a first heat exchanger fan 7, a flow equalizing cavity 10, a first air inlet 5 and a first air outlet 4; the first heat exchange cavity A is isolated from the flow equalizing cavity 10, and the first heat exchanger 6 and the first heat exchanger fan 7 are both installed in the first heat exchange cavity A, the first air inlet 5 is in communication with the first heat exchange cavity A and is arranged towards the first heat exchanger 6; the flow equalizing cavity 10 comprises a first end 101 and a second end 102, the first end 101 is close to the air outlet of the first heat exchanger fan 7, and the second end 102 is provided with the first air outlet 4; the center axes of the air outlet of the first heat exchanger fan 7, the flow equalizing cavity 10 and the first air outlet 4 are located on the same horizontal plane.
[0067] In the direct blowing type air conditioner heat exchange system, the first heat exchange fan 7 is inhaled by the first heat exchange cavity A after the heat exchange of the first heat exchanger 6, and the heat exchange air flow is blown out to the flow uniformizing cavity 10 through the air flow outlet of the first heat exchange fan 7. The heat exchange air flow moves from the first end 101 to the second end 102 in the flow uniformizing cavity 10, and is blown out by the first air flow outlet 4. The heat exchange air flow flows uniformly in the flow uniformizing cavity 10 and has greater wind power. Since the center axes of the air flow outlet of the first heat exchange fan 7, the flow uniformizing cavity 10 and the first air flow outlet 4 are located in the same horizontal plane, the heat exchange air flow blown out by the air flow outlet of the first heat exchange fan 7 is directly blown into the flow uniformizing cavity 10, without flowing through other fluid channels, without changing the wind direction of the heat exchange air flow, avoiding the loss of wind energy, ensuring greater air volume, and the heat exchange air flow moves from the first end 101 to the second end 102 in the flow uniformizing cavity 10 and is blown out by the first air flow outlet 4, ensuring uniform blowing out of the first air flow outlet 4, more uniform wind speed, and providing a more comfortable experience for the user. The function of the flow uniformizing cavity 10 is to ensure that the heat exchange air flow is more concentrated and uniformly blown out from the first air flow outlet 4 by introducing the heat exchange air flow into a closed cavity, so that the heat exchange air flow has greater thrust when sent out, thereby covering a longer distance, and the heat exchange air flow basically does not collide with the inner wall of the flow uniformizing cavity, reducing the noise of the heat exchange air flow and ensuring the quietness of the air conditioner.

When the air conditioner is working, the heat exchange air flow blown out by the flow uniformizing cavity 10 is the temperature adjusting air flow for adjusting the temperature of the temperature adjusting area. As shown in Figure 3 , the trajectories shown by "intake air" and "outlet air" are the movement trajectories of the temperature adjusting air flow. Generally, the air in the temperature adjusting area enters the first heat exchange cavity A under the action of the first heat exchange fan 7, the air entering the first heat exchange cavity A is adjusted in temperature by the first heat exchanger 6 to obtain the temperature adjusting air flow, and then the temperature adjusting air flow is blown out by the first heat exchange fan 7 and into the flow uniformizing cavity 10, and finally blown out by the first air flow outlet 4 communicating with the flow uniformizing cavity 10 to the temperature adjusting area to adjust the temperature of the temperature adjusting area, that is, to heat or cool the temperature adjusting area, realizing the function of the air conditioner.
[0069] As an embodiment, the direct blowing type air conditioner heat exchange system is installed on the condensing side of the air conditioner. When the air conditioner is working, generally, the condensing fan 11 inhales air, the condenser 9 exchanges heat with the air to absorb heat from the air or release heat to the air, the air is cooled or heated by the condenser 9 to obtain heat exchange air flow, and then the condensing fan 11 blows the heat exchange air flow into the flow uniformizing cavity 10, and then blows out through the first air flow outlet 4 communicating with the flow uniformizing cavity 10 and into the environment isolated from the temperature adjusting area.
