[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] Reference Figure 1-Figure 8A pull-out U-shaped air-conditioning heat pipe for convenient maintenance comprises a unit base 1 and a unit frame 2 fixedly mounted on the unit base 1. A unit maintenance door 3 is provided at one end of the unit frame 2 and a unit panel 5 is provided at the other end. A heat exchange coil 4 is provided on the unit base 1. A U-shaped heat pipe 6 connected to the heat exchange coil 4 is provided on the unit base 1. A front cover plate 62 and a rear cover plate 61 are provided at the front and rear ends of the U-shaped heat pipe 6 respectively. A concealed pull-out handle 9 is provided on the rear cover plate 61. A locking door assembly 10 for installing the unit maintenance door 3 is provided between the unit frame 2 and the unit maintenance door 3. A pull-out assembly 7 for facilitating the disassembly of the U-shaped heat pipe 6 is provided in the unit frame 2. When the air conditioning unit is used to control the temperature and humidity of the air, the obvious disadvantage is that the energy consumption is large and the operation and management cost is high. The U-shaped heat pipe 6 is located in the air conditioning unit. After application, this situation can be improved. The U-shaped heat pipe 6 automatically transfers heat when working, and does not require other additional equipment or power. It can work spontaneously through the drive of the heat exchange coil 4. The U-shaped heat pipe 6 can pre-cool the air and reduce the workload of the air conditioner. The U-shaped heat pipe 6 will first process the heat in the wind, and then heat the dehumidified air to achieve the dehumidification effect. In this process, the air can also be pre-cooled and reheated at the same time, killing two birds with one stone and doubling the effect. The device is provided with a pull-out component 7 in the unit frame 2 to reduce the difficulty of disassembling the U-shaped heat pipe 6, which can improve the convenience of loading and unloading the U-shaped heat pipe 6. After loading and unloading, the unit inspection door 3 can also be fixed by the locking door component 10 to ensure the stability of the operation of the air-conditioning unit.

[0026] The pull-out assembly 7 includes a guide rail base 71 fixedly mounted on the top of the inner cavity of the unit frame 2, and a guide rail 72 slidably connected to the U-shaped heat pipe 6 is fixedly mounted on the lower part of the guide rail base 71, and a mounting frame 73 is fixedly mounted on the bottom of the U-shaped heat pipe 6, and a load-bearing pulley 74 slidably contacting the unit base 1 is rotatably mounted on the mounting frame 73. When the U-shaped heat pipe 6 is inspected and repaired, the unit inspection door 3 can be removed from the unit frame 2 through the locking door assembly 10, and then the U-shaped heat pipe 6 can be pulled out through the concealed puller 9 arranged on the rear cover plate 61 of the U-shaped heat pipe 6. The guide rail 72 arranged on the upper part of the unit frame 2 can play a role in the U-shaped heat pipe 6. The guide rail 72 can ensure that the U-shaped heat pipe 6 moves accurately and stably on the predetermined path, and reduce the vibration and deviation of the U-shaped heat pipe 6 during the movement. The load-bearing pulley 74 cooperates with the mounting frame 73 to support the weight of the U-shaped heat pipe 6, and the rotation of the load-bearing pulley 74 converts the friction between the U-shaped heat pipe 6 and the unit base 1 from sliding friction to rolling friction, thereby greatly reducing the friction of the U-shaped heat pipe 6 during movement, improving its movement efficiency, and making it easier for the staff to pull it out.

[0027] Both sides of the guide rail 72 are provided with anti-friction balls 76 that are slidably connected to the U-shaped heat pipe 6. The provision of the anti-friction balls 76 reduces the friction loss between the U-shaped heat pipe 6 and the guide rail 72, thereby increasing the service life of the equipment components.

[0028] Two L-shaped fixing plates 75 slidably connected to the mounting frame 73 are provided on the unit base 1. The setting of the L-shaped fixing plates 75 achieves the effect of limiting the movement range of the load-bearing pulley 74, reducing the probability of deviation of the load-bearing pulley 74 during movement, thereby improving the stability of pulling out the U-shaped heat pipe 6.

[0029] Embodiment 2

[0030] Reference Figure 1-Figure 8 , this embodiment is basically the same as the first embodiment, and is more optimized in that the door lock assembly 10 includes a door lock member 101 arranged on one side of the unit frame 2 and the unit maintenance door 3, a door lock screw rod 103 threadedly connected to the unit frame 2 is rotatably installed on one side of the door lock member 101, and a door lock knob 102 is fixedly installed on one end of the door lock screw rod 103, and a door lock sleeve 104 threadedly connected to the door lock screw rod 103 is rotatably installed in the unit frame 2, and a limit ring groove 105 and a limit moment groove 106 that are interconnected are opened on the door lock sleeve 104, and a limit rod 107 is slidably installed in the limit ring groove 105 and the limit moment groove 106, and a limit spring 108 with one end fixedly connected to the unit frame 2 is fixedly installed on one side of the limit rod 107, and a push rod 109 is fixedly installed on one side of the limit rod 107, and one end of the push rod 109 slides and extends to the outside of the unit frame 2 When installing the unit maintenance door 3, the push rod 109 can be pressed to push the limit rod 107 from the limit ring groove 105 to the limit torque groove 106 to limit the rotation of the door lock sleeve 104, and then the door lock knob 102 is turned to mobilize the door lock screw rod 103 to rotate until one end of the door lock screw rod 103 is screwed into the door lock sleeve 104. When the door lock screw rod 103 moves, it will drive the door lock member 101 to squeeze the unit maintenance door 3 and the unit frame 2, thereby achieving the effect of fixing the unit maintenance door 3. At this time, release the push rod 109, and under the action of the limit spring 108, the limit rod 107 will automatically retreat to the limit ring groove 105. When the vibration of the equipment drives the door lock screw rod 103 to rotate, the door lock screw rod 103 will drive the door lock sleeve 104 to rotate together, thereby reducing the probability of the door lock screw rod 103 loosening and detaching from the equipment, and improving the stability of the equipment assembly.

[0031] Rubber-plastic strips 8 are respectively provided between the front cover plate 62 and the unit panel 5 and between the rear cover plate 61 and the unit inspection door 3. Since the rubber-plastic strips 8 are elastic, after the unit inspection door 3 is installed, the extrusion force generated by the door lock assembly 10 will form a sealing surface between it, the unit inspection door 3 and the unit panel 5, thereby effectively preventing external dust from entering the interior of the unit during the operation of the air-conditioning unit and affecting the operation of each component.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
