[0022] 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.

[0023] Reference Figure 1-Figure 2 The utility model provides an embodiment: a semi-flexible heat dissipation structure of a Stirling refrigerator, including a placement plate 1, a body 2 is fixedly connected to the left side of the top of the placement plate 1, a water pump 3 is fixedly connected to the right side of the top of the placement plate 1, so that the placement plate 1 can provide support for the water pump 3, a cooling pipe 4 is fixedly connected to the output end of the water pump 3, so that the water pump 3 can transport the coolant, the cooling pipe 4 has support rods 5 fixedly connected to the front and rear sides of the interior, the right top ends of the two support rods 5 are fixedly connected to the limiting plates 6, and the outsides of the two support rods 5 are sleeved with springs 7.

[0024] The outside of the support rod 5 is slidably connected to a pressure plate 8, so that the pressure plate 8 can slide more stably. The other end of the cooling tube 4 is fixedly connected to a cooling assembly, and the rear side of the cooling assembly is fixedly connected to a connecting tube 10, so that the heated coolant can enter the interior of the condenser 9 through the interior of the connecting tube 10 to be cooled. The cooling assembly includes a condenser 9, and the bottom of the condenser 9 is fixedly connected to the top of the placement plate 1. The other end of the cooling tube 4 is fixedly connected to the rear side of the condenser 9, so that the interior of the cooling tube 4 can be connected to the interior of the condenser 9. The rear top end of the connecting tube 10 is fixedly connected to the front side of the condenser 9, and the front top end of the connecting tube 10 is fixedly connected to the input end of the water pump 3.

[0025] In this way, the coolant inside the water pump 3 can enter the interior of the connecting pipe 10, and the exterior of the cooling pipe 4 is in contact with the exterior of the machine body 2, so that the cooling pipe 4 can absorb the heat emitted from the exterior of the machine body 2. The exterior of the pressure plate 8 is slidably connected to the interior of the cooling pipe 4, and the exterior of the limit plate 6 is in contact with the interior of the cooling pipe 4. One end of the spring 7 is fixedly connected to the left side of the limit plate 6, and the other end of the spring 7 is fixedly connected to the right side of the pressure plate 8, so that when the pressure plate 8 moves, the spring 7 will be compressed.

[0026] like Figure 1 and Figure 3 As shown: a loading frame 11 is fixedly connected to the bottom of the rear side of the body 2, and cavities 12 are provided inside the left and right sides of the loading frame 11, and a sliding plate 13 is slidably connected inside the cavity 12, and a pulling rod 14 is fixedly connected to the middle of the sliding plate 13, so that when the pulling rod 14 moves, it will drive the sliding plate 13 to move, and a spring 15 is sleeved on the outside of the pulling rod 14, and a fan 16 is provided inside the loading frame 11, and a snap-fitting groove 17 is provided in the middle of the left and right sides of the fan 16, one end of the spring 15 is fixedly connected to the inner wall of the far side of the two cavities 12, and the other end of the spring 15 is fixedly connected to the far side of the two sliding plates 13.

[0027] Therefore, when the sliding plate 13 moves, the spring 2 15 will be compressed, and the adjacent sides of the two pull rods 14 will respectively engage with the inside of the engaging groove 17, so that the pull rods 14 can fix the fan 16 inside the loading frame 11 by engaging with the engaging groove 17, and the middle part of the pull rods 14 is slidably connected to the inside of the cavity 12.

[0028] Compared with some existing technologies, the above content enables the device to absorb the heat dissipated from the outside of the device during use, and to dissipate the absorbed heat through the condenser 9, thereby achieving the effect of heat dissipation outside the device, thereby improving the heat dissipation efficiency of the device and achieving further heat dissipation of the device through the fan 16, and the fan 16 can be disassembled to facilitate the staff to clean and repair it, thereby improving the service life of the device.

[0029] Working principle: first start the machine body 2 to make the machine body 2 start to move, and then the machine body 2 will radiate heat to the outside. At this time, start the water pump 3 to make the water pump 3 transport the coolant in the connecting pipe 10 to the inside of the condenser 9, and then the coolant will enter the cooling pipe 4 through the inside of the condenser 9. Then turn off the water pump 3 to make the coolant in the cooling pipe 4 absorb the heat radiated from the machine body 2 to the outside. When the coolant absorbs too much heat and turns into water vapor, the water vapor will push the pressure plate 8 to make the pressure plate 8 slide on the outside of the support rod 5, and then the pressure plate 8 will compress the spring 7, and then the water vapor can bypass the pressure plate 8 and enter the inside of the water pump 3, so that the water vapor will enter the connecting pipe 10 through the inside of the water pump 3. The water vapor will enter the inside of the condenser tube 9 through the inside of the connecting tube 10 and be cooled into water droplets, and then it can continue to dissipate heat to the outside of the body 2. At the same time, the fan 16 is started to dissipate heat to the outside of the body 2. When the work is completed and the fan 16 needs to be inspected, the pull rod 14 can be pulled to make the pull rod 14 drive the sliding plate 13 to slide inside the cavity 12, so that the pull rod 14 will drive the sliding plate 13 to compress the spring 2 15, and then the pull rod 14 will disengage from the engagement groove 17, and then the fan 16 can be removed from the inside of the loading frame 11, so that the staff can clean and inspect it, thereby improving the service life of the device.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
