[0036] Embodiment 1

[0037] Reference Figure 1-Figure 2 , an integrated roof solar parking air conditioner, comprising a fixing mechanism and an air conditioning system, wherein the fixing mechanism is used to install the air conditioning system on the roof, and the air conditioning system is used to cool the interior of the vehicle when the vehicle is parked in summer;

[0038] The fixing mechanism includes:

[0039] A fixing frame 1 is installed on the roof of the vehicle and protects the air conditioning system;

[0040] A skylight window 3 is provided inside one end of the bottom of the fixing frame 1, so that the skylight window 3 can correspond to the position of the car sunroof, so that the air conditioning system can exchange heat with the wind at the skylight window 3 and the car sunroof to cool it down and then enter the car. When cooling is needed, just open the sunroof and start the air conditioning. No changes need to be made to the original car, and no professional installation is required. It is very suitable for online sales and market popularization. Ventilation holes 4 are evenly distributed inside the fixing frame 1 and on both sides of the heat sink, so that the heat generated by the air conditioning system inside the fixing frame 1 when it is working can be dissipated;

[0041] In this embodiment, the fixing frame 1 and the roof of the car only need to be fixed to the roof using common parts such as tiger claw buckles.

[0042] A seal, used to increase the sealing effect between the fixing frame 1 and the roof, and to isolate the air conditioning component and the heat sink;

[0043] The sealing member includes a first sealing strip and a second sealing strip. The first sealing strip is fixed to the bottom edge of the fixing frame 1, so that the position where the bottom of the fixing frame 1 is connected to the roof can be sealed through the first sealing strip, thereby reducing noise and foreign matter from entering. The second sealing strip is fixed to the bottom of the fixing frame 1 and the position corresponding to the skylight window 3, so that the cool air generated by the heat exchange of the air-conditioning system can directly enter the vehicle through the skylight window 3 and the car sunroof through the second sealing strip, and then the double sealing effect of the first sealing strip and the second sealing strip can achieve a better sealing effect after the parking air conditioner is installed;

[0044] The air conditioning system includes:

[0045] Air conditioning components, used to circulate and cool the air inside the vehicle;

[0046] The air conditioning assembly includes an air conditioning main unit 5, a cold air fan 6, an evaporator 7, a compressor 8, a condenser 9 and an electronic expansion valve 11. The air conditioning main unit 5 is fixed inside the other end of the bottom of the fixing frame 1, and the evaporator 7 is fixed on the inner side of one end of the bottom of the fixing frame 1. A cold air fan 6 is arranged at one end of the fixing frame 1 and located at the bottom of the evaporator 7, so that the coolness of the evaporator 7 is delivered to the vehicle through the skylight through the operation of the cold air fan 6. The condenser 9 is fixed at the other end of the bottom of the air conditioning main unit 5. The condenser 9 is connected to the air conditioning main unit 5, so that the operation of the air conditioning main unit 5 can drive the condenser 9 to work. The compressor 8 is connected to one side between the condenser 9 and the evaporator 7, so that the refrigerant in the condenser 9 can be delivered to the inside of the evaporator 7 through the compressor 8. The electronic expansion valve 11 is connected to the other side between the condenser 9 and the evaporator 7, so that the electronic expansion valve 11 can achieve the effects of adjusting the refrigerant flow, controlling the superheat, throttling and reducing the pressure, and controlling the evaporation liquid level.

[0047] In other embodiments, the electronic expansion valve 11 may also be used as a capillary tube. For those skilled in the art, adaptive structural replacement of the electronic expansion valve 11 or the capillary tube in the present invention belongs to the protection scope of the present invention.

[0048] In this embodiment, a micro horizontal compressor is used for refrigeration, and the refrigeration efficiency is much higher than that of a semiconductor refrigeration block.

[0049] Preferably, a heat insulating layer 12 is fixed inside the bottom end of the fixing frame 1 and outside the end of the evaporator 7 close to the compressor 8, so that the interior of the fixing frame 1 is divided into two parts, front and rear, by the heat insulating layer 12; and the bottom of the heat insulating layer 12 is in contact with the roof, so that the interior of the fixing frame 1 is separated, sealed and insulated by the heat insulating layer 12, and then the third sealing effect of the parking air conditioner can be achieved through the heat insulating layer 12. At the same time, the noise of the air-conditioning main unit 5 during operation is reduced by the heat insulating layer 12 and transmitted into the vehicle through the sunroof.

[0050] A heat sink, used to dissipate the heat generated by the air conditioning system when it is working;

[0051] The heat dissipation component is a cooling fan 10. A plurality of cooling fans 10 are arranged on the inner rear side of the other end of the fixing frame 1. Air enters through the ventilation holes 4, and the air outlets of the cooling fans 10 face the rear of the vehicle. At the same time, one end of the cooling fan 10 is located on the outer side of the rear of the fixing frame 1, so that the heat generated by the air-conditioning main unit 5 during operation can be discharged to the outside through the operation of the cooling fan 10.

[0052] The solar panel 2 is used to provide power to the air conditioning components and heat sinks, so that no oil or electricity is consumed, and the cooling capacity is automatically adjusted as the intensity of sunlight increases, the power generation increases, and the cooling capacity increases; at the same time, the solar panel has a reserved battery connection interface, which can also be used to replenish the battery on the vehicle, so that the battery is always fully charged to prevent the battery from accidentally running out of power. The solar panel expansion interface is reserved, and an additional large solar panel can be added to increase the cooling power.

[0053] In this embodiment, a solar panel of up to 300-400 watts can be installed on the top of the fixing frame 1. In other embodiments, a flexible solar panel can be attached to the front hood to increase the power generation capacity and thus increase the cooling capacity in the vehicle.

[0054] The use process of the integrated roof solar parking air conditioner provided by the present invention is as follows:

[0055] When used in summer, sunlight shines on the solar panel 2, and the solar panel 2 converts solar energy into electrical energy, which is supplied to the air-conditioning main unit 5, the cooling fan 6 and the cooling fan 10, so that the air-conditioning main unit 5 can deliver the refrigerant to the condenser 9, and then to the evaporator 7, and then absorb the heat of the surrounding environment through the evaporator 7, so as to reduce the ambient temperature. At the same time, the cooling fan 6 can blow the refrigerated air into the vehicle through the skylight 3 and the opened skylight, so as to cool the interior of the vehicle. At this time, the cooling fan 6 is used to transport the cooled air on the inside of the fixing frame 1 into the vehicle, and at the same time, the air in the vehicle is squeezed and transported upward on the outside of the cooling fan 6.

[0056] Embodiment 2:

[0057] The cooling fan 6 in the first embodiment can be deleted, and the remaining structures can be used normally, so that the evaporator 7 can absorb the heat of the surrounding environment and gradually cool the air in the car through the skylight 3 and the opened skylight.

[0058] Embodiment three:

[0059] Based on the above embodiment 1, the other end of the bottom of the parking air conditioner is equipped with a control panel for the evaporator 7 and the cooling fan 6, which is located opposite to the sunroof. The parking air conditioner can be started by opening the sunroof through the control panel.

[0060] Embodiment 4

[0061] Based on the above embodiment 1, the parking air conditioner is also scalable, and the solar output current can also be connected to the car starter battery to charge the battery, ensuring that the battery is always fully charged and the vehicle cannot be started due to power loss or old battery. A flexible solar panel can also be attached to the front hood to increase the solar panel area and increase the output power.
