[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution:

[0022] A spiral wound condenser includes a housing 1. A front groove 11 is formed on the front side of the housing 1. A cleaning window 16 is formed in the middle of the front groove 11. A sealing gasket 7 is fixed on the front groove 11 outside the cleaning window 16. Guide sleeves 12 are symmetrically fixed on both sides of the housing 1 behind the front groove 11. An inverted U-shaped bracket 4 is movably fitted onto the upper part of the housing 1 behind the guide sleeves 12. Guide grooves 13 are symmetrically formed on both sides of the housing 1. The two ends of the inverted U-shaped bracket 4 slide along the guide grooves 13 on both sides. The thickness of the two ends of the inverted U-shaped bracket 4 is greater than the depth of the guide grooves 13. An inclined surface 41 is provided on the rear side of the lower end of the inverted U-shaped bracket 4. A support frame 15 is fixedly installed on the top of the housing 1. A screw 3 is rotatably connected to the support frame 15 via bearings. The lower end of the screw 3... The screw 3 has a threaded end that passes through the middle of the inverted U-shaped bracket 4. The lower end of the screw 3 is rotatably connected to the top of the housing 1 via a bearing. An adjusting handle 31 is fixedly installed at the upper end of the screw 3. A door 2 is installed on the front side of the front groove 11. Connecting arms 21 are symmetrically fixed on both sides of the door 2. A connecting post 211 is fixedly installed on the inner wall of the rear end of the connecting arm 21. The connecting arm 21 moves through the guide sleeve 12. The connecting post 211 abuts against the inclined surface 41. The rear side of the door 2 abuts against the sealing gasket 7. By rotating the screw 3 counterclockwise, the inverted U-shaped bracket 4 moves upward, causing the lower end of the inclined surface 41 to move away from the front side of the connecting post 211, thus opening the door 2. This allows for thorough cleaning of the water and residue accumulated at the bottom of the inner side of the housing 1 through the cleaning window 16. To prevent long-term water accumulation inside the condenser from causing corrosion and to avoid the accumulation of residue affecting the cooling effect, the housing 1 is equipped with a main spiral tube 5 and a secondary spiral tube 6, which are wound together. Both ends of the main spiral tube 5 and the secondary spiral tube 6 are fixedly connected to connecting branch pipes, which are vertically inserted and fixed to both sides of the housing 1. A gaseous refrigerant inlet 14 is fixedly installed at the top of the housing 1, and a liquid refrigerant outlet 17 is fixedly installed at the bottom of the housing 1. Support feet are fixedly installed at the four corners of the bottom of the housing 1. During use, flowing cooling water can be supplied to the main spiral tube 5 and the secondary spiral tube 6, and gaseous refrigerant can be introduced into the housing 1 through the gaseous refrigerant inlet 14. Inside, the gaseous refrigerant condenses and forms water droplets that slide down the inner wall of the housing 1 to the bottom of the housing 1 and are discharged from the liquid refrigerant outlet 17. When it is necessary to clean the water and residue on the bottom of the inner side of the housing 1, the adjusting handle 31 can be manually turned counterclockwise to rotate the screw 3. The rotation of the screw 3 can move the inverted U-shaped bracket 4 upward, so that the inclined surface 41 is moved away from the front of the connecting column 211. At this time, the door 2 can be moved forward and removed from the housing 1. The water and residue on the bottom of the inner side of the housing 1 can then be cleaned through the cleaning window 16. After cleaning, the connecting arm 21 is aligned and inserted into the guide sleeve 12, and the door 2 is pressed against the sealing gasket 7. Then, the adjusting handle 31 is manually turned clockwise to rotate the screw 3.The rotation of screw 3 drives the inverted U-shaped bracket 4 downward along the guide groove 13. As the inverted U-shaped bracket 4 drives the inclined surface 41 downward, it pushes the connecting column 211 backward. The backward movement of the connecting column 211 drives the connecting arm 21 and the door 2 to move backward together, so that the door 2 tightly abuts against the sealing gasket 7, thereby sealing the cleaning window 16 through the door 2.

[0023] Both the main spiral tube 5 and the auxiliary spiral tube 6 have heat-conducting copper plates 8 fixedly installed on their outer walls. The heat-conducting copper plates 8 on the outer wall of the main spiral tube 5 are arranged along the spiral path of the main spiral tube 5, and the heat-conducting copper plates 8 on the outer wall of the auxiliary spiral tube 6 are arranged along the spiral path of the auxiliary spiral tube 6. By installing the heat-conducting copper plates 8, the heat exchange area between the main spiral tube 5 and the auxiliary spiral tube 6 and the gaseous refrigerant can be increased, thereby further improving the condensation efficiency. When the gaseous refrigerant comes into contact with the cold heat-conducting copper plates 8, condensation can occur on the surface of the heat-conducting copper plates 8, and heat exchange can be carried out with the heat-conducting copper plates 8. The heat-conducting copper plates 8 can quickly conduct the absorbed heat to the cooling water flowing inside the auxiliary spiral tube 6, thereby further accelerating the condensation of the gaseous refrigerant.

[0024] Working principle: During use, flowing cooling water can be supplied to the main spiral tube 5 and the auxiliary spiral tube 6, and gaseous refrigerant can be introduced into the interior of the housing 1 from the gaseous refrigerant inlet 14. After the gaseous refrigerant condenses, it will form water droplets that slide down the inner wall of the housing 1 to the bottom of the housing 1 and be discharged from the liquid refrigerant outlet 17. When the gaseous refrigerant comes into contact with the cold heat-conducting copper sheet 8, it can condense on the surface of the heat-conducting copper sheet 8 and exchange heat with the heat-conducting copper sheet 8. The heat-conducting copper sheet 8 can quickly conduct the absorbed heat to the cooling water flowing inside the auxiliary spiral tube 6, which can further accelerate the condensation of the gaseous refrigerant. When it is necessary to clean the water and residue on the bottom of the inner side of the housing 1, the adjusting handle 31 can be manually turned counterclockwise to drive the screw 3 to rotate. The rotation of the screw 3 can drive the inverted U-shaped bracket 4 to move upward, so that the inclined surface 41 Remove the front of the connecting post 211. At this point, the box door 2 can be moved forward and removed from the box body 1. The water and residue on the bottom inside the box body 1 can then be cleaned through the cleaning window 16. After cleaning, align the connecting arm 21 and insert it into the guide sleeve 12, and make the box door 2 abut against the sealing gasket 7. Then, manually turn the adjusting handle 31 clockwise to drive the screw 3 to rotate. The rotation of the screw 3 can drive the inverted U-shaped bracket 4 to move downward along the guide groove 13. As the inverted U-shaped bracket 4 drives the inclined surface 41 to move downward, the inclined surface 41 can push the connecting post 211 to move backward. The backward movement of the connecting post 211 can drive the connecting arm 21 and the box door 2 to move backward together, so that the box door 2 is tightly abutted against the sealing gasket 7, thereby sealing the cleaning window 16 through the box door 2.
