Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically a two-inlet, two-outlet double spiral tube evaporator. Background Technology

[0002] An evaporator is a type of indirect heat exchange device that achieves cooling by absorbing heat through the vaporization of liquid refrigerant. It is widely used in refrigeration systems and industrial evaporation. An evaporator is a heat transfer device used to convert liquid substances into a gaseous state. Typically, this is achieved by heating the liquid to boil and vaporize it, removing the vapor, thereby concentrating the solution or achieving a cooling effect. In a refrigeration system, the evaporator is one of the four core components, responsible for exchanging heat between the low-temperature liquid refrigerant and the surrounding air or liquid, absorbing heat and vaporizing to achieve cooling. Traditional evaporators are mostly single-spiral tubes, which have a small contact area with hot air, resulting in poor cooling performance. To improve its cooling effect, a double-inlet, double-outlet double-spiral tube evaporator has been proposed.

[0003] For example, the spiral tube evaporator for refrigeration and air conditioning equipment disclosed in the authorization announcement number CN221724444U includes a mounting box, pipe hole A, air inlet, air outlet, cover plate, cooling water tank, heat dissipation fins, water injection hole, and hole cover. The mounting box has pipe holes A in the upper and lower parts of the left end, the air inlet is located at the upper front end of the mounting box, the air outlet is located at the upper rear end of the mounting box, the cover plate is installed on the top of the mounting box, the cooling water tank is fixed to the middle of the bottom end of the cover plate, the heat dissipation fins are distributed at the bottom front and rear ends of the cooling water tank, the water injection hole is located in the middle of the cover plate, and the hole cover is installed on the water injection hole.

[0004] Although it solves the problem that the evaporator used in air conditioners does not have a cold storage effect, and the evaporator needs to be turned on for a long time if long-term cooling is required, it also solves the problem of insufficient energy saving.

[0005] However, this does not solve the problems of existing evaporators being difficult to disassemble and use quickly, and the inability to perform circumferential rolling cleaning of dust on the surface of the spiral copper tubes, which hinders the increase of cooling area and affects the cooling effect. Utility Model Content

[0006] The purpose of this invention is to provide a double-inlet, double-outlet double spiral tube evaporator to solve the problems mentioned in the background art, such as the evaporator being inconvenient to quickly disassemble and use, and the need for circumferential rolling to clean the dust on the surface of the spiral copper tube, which is not conducive to increasing the cooling area and affecting the cooling effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-inlet, double-outlet double-spiral tube evaporator, comprising a support plate and a cylinder. The cylinder is positioned above the support plate, and mounting rings are symmetrically arranged on the surface of the cylinder. A connector is symmetrically arranged at the top of the support plate. A connecting plate is provided at the bottom of each mounting ring, and a connector post is provided at the bottom of each connecting plate. The connector post is slidably connected to the connector. A limiting post is slidably arranged on the side wall of each connector. A spring is provided on the surface of each limiting post, and both ends of the spring are connected to the connector and the limiting post, respectively. A groove is provided on the surface of each connector, and the limiting post is slidably connected to the groove. Two sets of spiral copper tubes are arranged adjacently inside the cylinder. One end of each spiral copper tube has an inlet, and the other end of each spiral copper tube has an outlet. An air inlet is provided at the top of the cylinder, and an air outlet is provided at the bottom of the cylinder.

[0008] Preferably, the cylindrical surfaces on both sides of the air inlet are provided with limiting rails, and a filter screen is slidably arranged between the two sets of limiting rails, and a handle is provided on the surface of the filter screen.

[0009] Preferably, a drive seat is provided on the side wall of the cylinder, and an adapter frame is provided on the side wall of the cylinder on one side of the drive seat.

[0010] Preferably, a servo motor is provided on the side wall of the drive base, and a worm gear is installed at the output end of the servo motor, and the worm gear is movably connected to the drive base.

[0011] Preferably, a hollow rod is movably installed inside the drive seat on one side of the worm, and one end of the hollow rod extends into the interior of the cylinder and is movably connected to the cylinder. A worm wheel is fitted on the surface of the hollow rod inside the drive seat, and the worm and the worm wheel mesh with each other.

[0012] Preferably, the other end of the hollow rod extends into the interior of the adapter frame and is movably connected to the adapter frame, and a flexible hose is installed at the end of the adapter frame away from the drive seat.

[0013] Preferably, the surface of the hollow rod is provided with multiple sets of brush holders at equal intervals, and the brush holders are fixedly connected to the hollow rod.

[0014] Preferably, each of the hollow rods on one side of the brush holder is provided with a nozzle, and the nozzle is connected to the hollow rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the evaporator not only realizes quick disassembly and use and the circumferential rotation and sweeping cleaning of dust on the surface of the spiral copper tube, which facilitates the increase of the cooling area and avoids dust accumulation on the surface of the spiral copper tube, but also improves the cooling effect.

[0016] (1) Before using the evaporator, connect the inlet to the refrigerant pipe and the outlet to the compressor. The refrigerant enters the spiral copper tube through the inlet and expands and vaporizes to absorb heat. The fan blows external air into the cylinder through the filter screen and air inlet. The filter screen filters out impurities and dust in the air. The airflow passes over the surface of the spiral copper tube and is cooled by the spiral copper tube. The cooled gas is discharged through the air outlet to complete the operation of the evaporator. The setting of two sets of spiral copper tubes can increase the contact area between the spiral copper tube and the airflow, which can improve its cooling effect. During use, dust will accumulate on the surface of the filter screen. When it is necessary to clean the filter screen... To remove dust from the surface, move the handle, which will cause the filter to slide inside the limiting track. This will allow you to remove the filter. After cleaning the dust from the filter surface, reinstall it. To quickly remove the cylinder, pull out the limiting post. The limiting post will cause the spring to deform, pulling the limiting post out of the groove. Move the cylinder upwards, which will move the mounting ring. The mounting ring will then move the connecting plate and the insertion post. Pull the insertion post out of the insertion seat to remove the cylinder from the surface of the support plate. Reversing the operation will allow you to quickly install the cylinder on the support plate. This allows for quick assembly and disassembly, facilitating the increase of cooling area and improving cooling efficiency.

[0017] (2) After long-term use, dust will also stick to the surface of the spiral copper tube. The servo motor drives the worm gear to rotate, and the worm gear drives the hollow rod to rotate through the worm wheel. The hollow rod drives the brush holder to rotate, and the brush holder scrapes and cleans the dust on the surface of the spiral copper tube. At the same time, the flexible hose is connected to the external air pump. The air pump pumps the gas through the flexible hose and the adapter to the inside of the hollow rod. The airflow moves inside the hollow rod and is sprayed out from the nozzle. The airflow blows the cleaned dust out from the air inlet and air outlet to clean the spiral copper tube, avoiding the accumulation of dust on the surface of the spiral copper tube and affecting the cooling effect. It is convenient to perform circumferential rolling cleaning of the dust on the surface of the spiral copper tube, and avoids the accumulation of dust affecting the cooling effect of the spiral copper tube.

[0028] Example 1

[0029] Please see Figure 1-6This utility model provides an embodiment of a double-inlet, double-outlet double-spiral tube evaporator, including a support plate 1 and a cylinder 2. The cylinder 2 is positioned above the support plate 1, and mounting rings 3 are symmetrically arranged on the surface of the cylinder 2. Insertion seats 4 are symmetrically arranged at the top of the support plate 1. Connecting plates 22 are provided at the bottom of each mounting ring 3, and insertion posts 23 are provided at the bottom of each connecting plate 22. The insertion posts 23 are slidably connected to the insertion seats 4. Limiting posts 24 are slidably arranged on the side walls of each insertion seat 4. Springs 25 are provided on the surface of each of the cylinders 24, and the two ends of the springs 25 are connected to the plug-in base 4 and the limiting post 24 respectively. The surface of each plug-in post 23 is provided with a groove 26, and the limiting post 24 is slidably connected to the groove 26. Two sets of spiral copper tubes 13 are arranged adjacent to each other inside the cylinder 2. One end of each spiral copper tube 13 is provided with an inlet 14, and the other end of each spiral copper tube 13 is provided with an outlet 15. An air inlet 9 is provided at the top of the cylinder 2, and an air outlet 5 is provided at the bottom of the cylinder 2.

[0030] Limiting rails 8 are provided on the surface of the cylinder 2 on both sides of the air inlet 9, and a filter screen 6 is slidably arranged between the two sets of limiting rails 8, and a handle 7 is provided on the surface of the filter screen 6.

[0031] Before using the evaporator, connect the inlet 14 to the refrigerant pipe and the outlet 15 to the compressor. The refrigerant enters the spiral copper tube 13 through the inlet 14, expands, vaporizes, and absorbs heat. External air is blown into the cylinder 2 through the filter screen 6 and air inlet 9 by a fan. The filter screen 6 filters out impurities and dust from the air. The airflow passes over the surface of the spiral copper tube 13, which cools the airflow. The cooled gas is then discharged through the outlet 5, completing the operation of the evaporator. The two sets of spiral copper tubes 13 increase the contact area between the spiral copper tubes 13 and the airflow, improving the cooling effect. During use, dust will accumulate on the surface of the filter screen 6. Cleaning of the dust on the filter screen 6 is necessary. When the filter screen 6 is removed, the handle 7 is moved and slides inside the limiting track 8. After cleaning the dust on the surface of the filter screen 6, it can be reinstalled. If the cylinder 2 needs to be removed quickly, the limiting post 24 is pulled out. The limiting post 24 causes the spring 25 to deform and pull the limiting post 24 out of the groove 26. The cylinder 2 is moved upward and the mounting ring 3 is moved. The mounting ring 3 causes the connecting plate 22 and the plug-in post 23 to move. The plug-in post 23 is pulled out from the plug-in seat 4 and the cylinder 2 can be removed from the surface of the support plate 1. The reverse operation can quickly install the cylinder 2 on the support plate 1, realizing quick disassembly and assembly, which facilitates the increase of the cooling area and improves the cooling effect.

[0032] A drive seat 10 is provided on the side wall of the cylinder 2. An adapter frame 11 is provided on the side wall of the cylinder 2 on one side of the drive seat 10. A servo motor 19 is provided on the side wall of the drive seat 10. The servo motor 19 plays the role of power drive. A worm gear 20 is installed at the output end of the servo motor 19, and the worm gear 20 is movably connected to the drive seat 10.

[0033] A hollow rod 16 is movably installed inside the drive seat 10 on one side of the worm 20, and one end of the hollow rod 16 extends into the interior of the cylinder 2 and is movably connected to the cylinder 2. A worm wheel 21 is fitted on the surface of the hollow rod 16 inside the drive seat 10, and the worm 20 and the worm wheel 21 mesh with each other.

[0034] The other end of the hollow rod 16 extends into the interior of the adapter frame 11 and is movably connected to the adapter frame 11. A flexible hose 12 is installed at the end of the adapter frame 11 away from the drive seat 10. Multiple sets of brush holders 17 with equal spacing are provided on the surface of the hollow rod 16, and the brush holders 17 are fixedly connected to the hollow rod 16.

[0035] The surface of the hollow rod 16 on one side of the brush holder 17 is provided with a nozzle 18, and the nozzle 18 is connected to the hollow rod 16.

[0036] After prolonged use, dust will accumulate on the surface of the spiral copper tube 13. Turning on the servo motor 19 drives the worm gear 20 to rotate. Through the meshing of the worm gear 20 and worm wheel 21, the worm gear 20 drives the hollow rod 16 to rotate via the worm wheel 21. The hollow rod 16 then drives the brush holder 17 to rotate, which scrapes and cleans the dust from the surface of the spiral copper tube 13. Simultaneously, the flexible hose 12 is connected to an external air pump. The air pump pressurizes the air through the flexible hose 12 and adapter 11 into the interior of the hollow rod 16. The airflow moves inside the hollow rod 16 and is ejected from the nozzle 18, blowing the cleaned dust out through the air inlet 9 and air outlet 5 to clean the spiral copper tube 13. This prevents dust accumulation on the surface of the spiral copper tube 13 from affecting the cooling effect and facilitates circumferential rolling cleaning of the dust on the surface of the spiral copper tube, avoiding dust accumulation that could affect the cooling performance of the spiral copper tube.

[0037] Work steps

[0038] Before using the evaporator, connect the inlet 14 to the refrigerant pipe and the outlet 15 to the compressor.

The airflow passes over the surface of the spiral copper tube 13, which cools the airflow. The cooled gas is discharged through the outlet 5, thus completing the operation of the evaporator. Two sets of... The spiral copper tube 13 increases the contact area between the spiral copper tube 13 and the airflow, thus improving its cooling effect. During use, dust will accumulate on the surface of the filter screen 6. When it is necessary to clean the dust on the surface of the filter screen 6, move the handle 7. The handle 7 will drive the filter screen 6 to slide inside the limiting track 8, and the filter screen 6 can be removed.

The limiting post 24 will drive the spring 25 to deform, and the limiting post 24 will move the spring 25 to move the limiting post 25 to move the limiting post 25 to move the spring ... The column 24 is pulled out from the groove 26, and the cylinder 2 moves upward. The cylinder 2 drives the mounting ring 3 to move, and the mounting ring 3 drives the connecting plate 22 and the insertion post 23 to move. The insertion post 23 is pulled out from the insertion seat 4, and the cylinder 2 can be removed from the surface of the support plate 1. The reverse operation can quickly install the cylinder 2 on the support plate 1. After long-term use, dust will also adhere to the surface of the spiral copper tube 13. The servo motor 19 drives the worm gear 20 to rotate, and the worm gear 20 drives the hollow rod 16 to rotate through the worm wheel 21. The hollow rod 16 drives the brush holder 17 to rotate, and the brush holder 17 scrapes and cleans the dust on the surface of the spiral copper tube 13.
