[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a condenser assembly for a helicopter air conditioning system includes a mounting frame 1 and a mounting plate 5. A heat exchange tube 2 is arranged inside the mounting frame 1. The heat exchange tube 2 is distributed in a serpentine line. One end of the heat exchange tube 2 is fixedly connected to an air inlet 3, and the other end of the heat exchange tube 2 is fixedly connected to an air outlet 4. There are two mounting plates 5, which are symmetrically distributed on both sides of the mounting frame 1. Two fixing holes 7 are respectively opened on both sides of the mounting plate 5. A detachable fixing mechanism is provided between the mounting plate 5 and the mounting frame 1. The detachable fixing mechanism consists of a U-shaped plate 6, a movable plate 13, and a card block. 15 and a connecting plate 17, the mounting plate 5 is fixedly connected to the U-shaped plate 6 at one end close to the mounting frame 1, and connecting plates 17 are fixedly installed on both sides of the end of the mounting frame 1 close to the mounting plate 5, and two limiting holes 18 are respectively provided on the two connecting plates 17. A matching hole 11 is provided on the U-shaped plate 6 at the extended position of the limiting hole 18, and two movable plates 13 are provided between the U-shaped plate 6 and the mounting plate 5. Two clamping blocks 15 are fixedly connected to one end of the movable plate 13 close to the U-shaped plate 6, and the clamping blocks 15 and the limiting holes 18 are adapted to each other. A reset mechanism is provided at one end of the movable plate 13 close to the mounting plate 5.

[0021] Among them, the reset mechanism is composed of a guide column 12 and a spring 16. There are two guide columns 12. The two guide columns 12 slide through the two through holes 14 opened on the movable plate 13 respectively. The two ends of the guide column 12 are fixedly connected to the mounting plate 5 and the U-shaped plate 6 respectively. Two springs 16 are also fixedly connected between the movable plate 13 and the mounting plate 5. The two springs 16 are respectively wound around the outer surfaces of the two guide columns 12.

[0022] The movable plate 13 can be guided by the provided guide column 12 , and the movable plate 13 can be pressed tightly against the U-shaped plate 6 by the provided spring 16 .

[0023] The U-shaped plate 6 is fixedly connected to two sides of one end close to the installation frame 1 with positioning plates 10 , and the distance between the two positioning plates 10 is equal to the sum of the widths of the installation frame 1 and the two connecting plates 17 .

[0024] With such arrangement, when the installation frame 1 is installed, the two positioning plates 10 can play a positioning role on both sides of the installation frame 1 .

[0025] Among them, multiple heat exchange copper plates 9 are arranged inside the installation frame 1. The multiple heat exchange copper plates 9 are in a linear array. The heat exchange copper plates 9 are slidably sleeved on the outer surface of the heat exchange tube 2, and the two ends of the heat exchange copper plates 9 are fixedly connected to the inner wall of the installation frame 1 respectively.

[0026] The multiple heat exchange copper plates 9 can quickly conduct the heat on the heat exchange tube 2, thereby greatly increasing the heat dissipation area of ​​the condenser. At the same time, the heat exchange copper plates 9 can also support the heat exchange tube 2, thereby improving the stability of the heat exchange tube 2.

[0027] A stopper 19 is provided on the side of the movable plate 13 , and a slider 20 is fixedly connected to the bottom of the stopper 19 . The slider 20 is slidably installed in a slide groove 21 provided in the U-shaped plate 6 .

[0028] When disassembling the mounting frame 1, the movable plate 13 can be moved away from the mounting frame 1 by hand, so that the block 15 is pulled out of the limiting hole 18. At this time, the stop block 19 is moved between the movable plate 13 and the U-shaped plate 6 to limit the movable plate 13, thereby preventing the block 15 from affecting the disassembly and assembly of the mounting frame 1.

[0029] Among them, a plurality of reinforcement plates 8 are fixedly connected between the mounting plate 5 and the U-shaped plate 6 .

[0030] The reinforcement plate 8 can improve the firmness of the connection between the mounting plate 5 and the U-shaped plate 6 .

[0031] The utility model provides a condenser assembly for a helicopter air conditioning system, and the specific working principle is as follows:

[0032] During use, hot gas is introduced into the heat exchange tube 2 through the air inlet 3. The serpentine-shaped heat exchange tube 2 can quickly dissipate the heat in the steam into the surrounding air, and the multiple heat exchange copper plates 9 can quickly conduct the heat on the heat exchange tube 2, thereby greatly increasing the heat dissipation area of ​​the condenser. At the same time, the heat exchange copper plates 9 can also support the heat exchange tube 2, thereby improving the stability of the heat exchange tube 2. The detachable fixing mechanism can greatly facilitate the disassembly and assembly of the installation frame 1, thereby facilitating the replacement and maintenance of the condenser by the staff.

[0033] The specific working principle of the detachable fixing mechanism is to fix the two mounting plates 5 on the housing of the refrigeration system by the cooperation of the fixing bolts and the fixing holes 7, so that the spacing between the two U-shaped plates 6 is equal to the length of the mounting frame 1. The two U-shaped plates 6 can limit the two sides of the mounting frame 1, and the two positioning plates 10 on the U-shaped plate 6 can limit the other two sides of the mounting frame 1. Then, move the movable plate 13 away from the mounting frame 1 by hand, and move the stopper 19 between the movable plate 13 and the U-shaped plate 6 to limit the movable plate 13. To prevent the block 15 from affecting the assembly and disassembly of the installation frame 1, the spring 16 will be compressed at this time, and then the installation frame 1 is inserted between the two U-shaped plates 6. When the limiting hole 18 on the connecting plate 17 and the matching hole 11 on the U-shaped plate 6 are aligned, the stopper 19 is pulled out from between the movable plate 13 and the U-shaped plate 6. Under the action of the spring 16 restoring the deformation, the movable plate 13 will move toward the direction of the U-shaped plate 6, thereby driving the block 15 to pass through the matching hole 11 and the limiting hole 18 in sequence, thereby completing the installation and fixation of the installation frame 1. When disassembling, only directional operation is required.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
