[0031] In order to enable the personnel in the technical field to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In order to solve the technical problems of large volume, inconvenient portability and mobility in the related art, the present invention provides a heat exchange system and a portable outdoor air conditioner having the same.

[0033] Such as Figures 4 to 12As shown in the figure, the heat exchange system includes an air duct structure 10, a fan blade 20, a first motor 30, an evaporator 40, and a condenser 50. The air duct structure 10 has a first air inlet 101, a first air outlet 102 communicating with the first air inlet 101, and a second air outlet 103. The first motor 30 is arranged in the air duct structure 10 and corresponds to the first air inlet 101. The first motor 30 is drivingly connected to the fan blade 20 and is arranged outside the air duct structure 10 and corresponds to the first air outlet 102. The condenser 50 is arranged outside the air duct structure 10 and corresponds to the second air outlet 103. The first motor 30 drives the fan blade 20 to rotate. Under the action of the fan blade 20, the air flow enters the air duct structure 10 through the first air inlet 101. A part of the air flow flows out through the first air outlet 102, is sent out of the heat exchange system after heat exchange with the evaporator 40, and is used to provide cold air. Another part of the air flow flows out through the second air outlet 103, is sent out of the heat exchange system after heat exchange with the condenser 50, and is used to cool the condenser 50.

[0034] In this way, the heat exchange system adopts a single driving device, that is, one fan blade 20 and one first motor 30 for driving its rotation are provided. Compared with the heat exchange system adopting a double driving device in the related art, it is more power-saving and is beneficial to the long-term use of the outdoor portable air conditioner. Through the air duct structure 10, double-duct air volume is provided for heat exchange with the evaporator and the condenser at the same time. The heat exchange system and the outdoor portable air conditioner provided by the present application have fewer parts, are beneficial to space layout, reduce the external volume of the air conditioner, and are convenient to carry and move.

[0037] As Figure 4As shown, the heat exchange system further includes a second motor 70, a battery (not shown), a temperature detector (not shown), and a controller (not shown). The second motor 70 is used to be drivingly connected to the air-sweeping plate 60 to provide power for the heat exchange system. The temperature detector is used to detect the temperature of the battery. The controller is electrically connected to the first motor 30 and the temperature detector. When the temperature detector detects that the temperature of the battery is higher than the preset temperature, the controller controls the air-sweeping plate 60 to rotate towards the second air outlet section 13 through the second motor 70 to increase the air volume entering the first air outlet section 12. When the temperature detector detects that the temperature of the battery is lower than the preset temperature, the controller controls the air-sweeping plate 60 to rotate towards the first air outlet section 12 through the first motor 30 to increase the air volume entering the second air outlet section 13.

[0038] In this way, the present application can also adjust the air volume of the double air ducts, is applicable to the operation of the battery in different states, is more conducive to improving the service life of the battery, and is beneficial to further improving the performance of the outdoor portable air conditioner.

When the temperature detector detects that the temperature of the battery is higher than the preset temperature, the controller controls to reduce the load of the compressor 80. When the temperature detector detects that the temperature of the battery is lower than the preset temperature, the controller controls to increase the load of the compressor 80. The compressor 80 is correspondingly arranged with the second air outlet 103. Along the flowing direction of the air flow, the compressor 80 is located upstream of the condenser 50, and the air flow flowing out through the second air outlet 103 is also used to cool the compressor 80.

During assembly, the left rotating shaft of the air deflector plate 60 is centered and placed into the left rotating shaft hole of the air duct structure 10, the flat shaft groove 621 on the right side is clamped onto the motor shaft of the second motor 70 on the right side, and the middle rotating shaft 63 is clamped into the eagle beak position of the air duct structure 10.

[0056] When the air conditioner is powered on, the second motor 70 is reset to drive the air deflector 60 to an angle at the center of the air duct circle. During the operation of the air conditioner, the battery temperature is detected. When the battery temperature of the air conditioner is too high and protection is required, the program controls the power reduction to reduce the load on the compressor. At this time, the air deflector swings downward by a certain angle, the air inlet end face of the first air outlet 102 increases, and the air inlet end face of the second air outlet 103 decreases. The air volume mainly flows in the direction of the first outlet for heat exchange of the evaporator 40 to send out cold air. When it is detected that the battery temperature of the air conditioner is in the low temperature range, the power can be increased to increase the load on the compressor 80. At this time, the air deflector 60 swings upward by an angle, the area of the first air outlet 102 decreases, and the air inlet end face of the second air outlet 103 increases. The air volume mainly flows in the direction of the second outlet for heat dissipation of the condenser 50 and the compressor 80. By controlling the rotation of the air deflector 60, the present application adjusts the air deflection angle, effectively utilizes the air volume inside the air duct structure 10 for heat exchange, and protects the battery at the same time, thereby improving the service life of the air conditioner.

[0057] Compared with the existing air conditioners, the present application provides a single-drive device two-way air duct system, which saves internal space, is small in size, light in weight, and convenient for carrying and transportation, and can be applied to more integrated and portable air conditioners. At the same time, by adjusting the air deflection angle, the air volume inside the air duct is distributed, the air volume is fully utilized, and the battery is protected at the same time, which helps to extend the service life of the air conditioner.
