Description

Technical Field

[0001] This utility model relates to the field of refrigeration system technology, specifically to a device for improving the superheat of a refrigeration system. Background Technology

[0002] A refrigeration system is a system that uses external energy to transfer heat from a substance (or environment) with a higher temperature to a substance (or environment) with a lower temperature. Its working principle is to exchange heat through changes in state. A refrigeration system generally consists of a refrigerant, a compressor, a condenser, an expansion valve, and an evaporator. It can be divided into vapor refrigeration systems, air refrigeration systems, and thermoelectric refrigeration systems.

[0003] The above-mentioned technical conditions also have shortcomings: the condenser tubes and fins in the existing refrigeration system need to be installed outdoors for heat dissipation to achieve heat exchange. However, dust in the external environment will affect the heat exchange efficiency of the fins, resulting in a decrease in the efficiency of the refrigeration system after a long period of use.

[0004] Based on this, the present invention designs a device to improve the superheat of the refrigeration system in order to solve the above problems. Utility Model Content

[0007] By adopting the above technical solution, dust on the condenser tubes and fins can be blown away, thereby reducing the impact of dust on heat exchange efficiency.

[0008] Preferably, the sleeve is threaded with a knob, and multiple positioning holes are provided at the top of the telescopic tube. The bottom of the knob can be inserted into the positioning hole. Four sets of limiting blocks are fixedly provided on the outer wall of the transmission shaft, and grooves that match the four sets of limiting blocks are provided on the inner side of the transmission tube.

[0009] By adopting the above technical solution, the distance between the sleeve and the telescopic tube can be adjusted, thus making it applicable to condenser tubes and fins of different thicknesses and increasing the applicability of this device.

[0010] Preferably, the two sets of support tubes away from the drive motor are provided with sliding grooves, and one side of the lifting plate is slidably connected to the support tubes through the sliding grooves.

[0011] By adopting the above technical solution, the lifting plate becomes more stable when moving up and down.

[0012] Preferably, one end of the lifting plate near the lead screw is slidably connected to the inside of the support tube.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] A device for improving superheat in a refrigeration system includes two sets of sleeves 1. A telescopic tube 2 is provided on one side of each set of sleeves 1, and the telescopic tube 2 can slide inside the sleeve 1. Support tubes 3 are fixedly installed on both sets of sleeves 1 and both sets of telescopic tubes 2. A top plate 4 is fixedly connected to the top of each set of support tubes 3 to restrict the position of the support tubes 3. A drive motor 5 is fixedly connected to one side of one set of telescopic tubes 2. A transmission shaft 6 is fixedly connected to the output shaft of the drive motor 5. A transmission tube 7 is connected to one end of the transmission shaft 6. First bevel gears 8 are fixedly connected to the outer walls of both the transmission shaft 6 and the transmission tube 7. Lead screws 9 are rotatably connected to the top of the inner walls of each set of support tubes 3 near the drive motor 5. The bottom ends of both sets of lead screws 9 are fixedly connected to second bevel gears 10 that mesh with the first bevel gear 8. When the first bevel gear 8 rotates, it can drive the second bevel gear 10 to rotate, thereby changing the direction of rotation. Lifting plates 11 are threadedly connected to both sets of lead screws 9. Multiple nozzles 12 are connected to the bottom of the lifting plates 11. Air pumps 13 are fixedly connected to one side of another set of telescopic pipes 2 and one set of sleeves 1. An air supply pipe 14 is connected to the air outlet of the air pump 13. The air supply pipe 14 is connected to multiple nozzles 12. The air pump 13 can generate high-pressure air, which is then sprayed out through the nozzles to flush the dust on the condenser tubes and fins, thereby reducing the dust on the condenser tubes and fins and improving their heat exchange effect.

[0027] Furthermore, a knob 17 is threaded onto the sleeve 1, and multiple positioning holes 16 are provided on the top of the telescopic tube 2. The bottom of the knob 17 can be inserted into the positioning hole 16, thereby positioning the telescopic tube 2 inside the sleeve 1. Four sets of limiting blocks 18 are fixedly provided on the outer wall of the drive shaft 6, and grooves that match the four sets of limiting blocks 18 are provided on the inner side of the drive tube 7, so that the drive shaft 6 can drive the drive tube 7 to rotate, and the drive tube 7 and the drive shaft 6 can slide relative to each other.

[0028] Furthermore, grooves 15 are provided on both sets of support pipes 3 that are far from the drive motor 5. One side of the lifting plate 11 is slidably connected to the support pipe 3 through the grooves 15, which improves the stability of the lifting plate 11 when it moves.

[0029] Furthermore, one end of the lifting plate 11 near the lead screw 9 is slidably connected to the inside of the support tube 3, making the lifting plate 11 more stable when moving up and down, thus enabling it to effectively remove dust from the condenser tube and fins.

[0030] Furthermore, one end of the transmission tube 7 is rotatably connected to one side of the inner wall of the telescopic tube 2, making the transmission tube 7 more stable when rotating and increasing its performance.

[0031] The implementation principle of this embodiment is as follows: When in use, two sets of sleeves 1 and two sets of telescopic tubes 2 are installed on the left and right sides of the fins. Then, according to the thickness of the fins, the distance of the telescopic tubes 2 is adjusted by pulling them. Then, the position of the telescopic tubes 2 is positioned by inserting the knob 17 into the positioning hole 16. When it is necessary to clean the dust on the front and back of the fins, the drive motor 5 and the air pump 13 are started. The output shaft of the drive motor 5 drives the transmission shaft 6 and the transmission tube 7 to rotate, so that the first bevel gear 8 rotates, which in turn drives the second bevel gear 10 and the lead screw 9 to rotate. Through the threaded connection between the lifting plate 11 and the lead screw 9, the lifting plate 11 can move up and down. At this time, the air pump 13 draws in air and pressurizes it, and then transmits it to multiple nozzles 12 through the air supply pipe 14, so as to flush the front and back of the fins, thereby reducing the dust on the fins and improving the heat exchange effect of the fins. After the cleaning work is completed, the lifting plate 11 is controlled to move to a position close to the top plate 4, which will not affect the normal operation of the condenser and the fins.
