Description

Technical Field

[0001] This utility model relates to the field of finned evaporator technology, specifically to a finned evaporator with a high-efficiency defrosting function. Background Technology

[0002] During the cooling process of a finned evaporator for liquids or gases, frost will condense on the surface of the fins, preventing the fins from fully contacting the outside air. This reduces the cooling efficiency of the evaporator and affects its operation. Therefore, defrosting is necessary periodically.

[0003] Chinese Patent (Authorization Announcement No. CN220489454U) discloses a tube-type finned evaporator with high-efficiency defrosting function, comprising two rows of heat exchange tubes connected together in a serpentine arrangement. The straight tubes of the front row of heat exchange tubes are provided with a number of first fins, and the straight tubes of the rear row of heat exchange tubes are provided with a number of pairs of second fins. The long sidewalls of the first and second fins are respectively provided with grooves. The first and second fins are provided with strip-shaped holes corresponding to the grooves. The strip-shaped holes are located between two adjacent straight tubes of the heat exchange tubes. The first and second fins are provided with defrosting components, which include spiral resistance wires and straight resistance wires. The spiral resistance wires are connected in the strip-shaped holes and contact the inner wall of the strip-shaped holes. The straight resistance wires are passed through the corresponding first and second fins and connected to the corresponding spiral resistance wires. The straight resistance wires and spiral resistance wires on each row of first or second fins are connected in a serpentine manner.

[0004] The aforementioned finned evaporator heats the first and second fins to defrost by energizing a linear resistance wire. However, the frost on the fins needs to melt into water before it can drip off, meaning the frost needs to adhere to the fin surface for a period of time. This prolongs the adhesion time of the frost on the fins, thus reducing the defrosting efficiency. Utility Model Content

[0005] To address the aforementioned issues, a finned evaporator with a highly efficient defrosting function is provided. This evaporator utilizes an external heating device in conjunction with an inlet pipe to transport hot air to the interior of an outlet pipe, where it is then sprayed out from a nozzle. The hot air melts the frost on the surface of the evaporator body. Simultaneously, a motor drives a screw to rotate, causing a cleaning brush on the outside of the screw to reciprocate, thus quickly and efficiently removing frost from the evaporator body surface and accelerating the defrosting process.

[0006] To address the problems of existing technologies, this utility model provides a finned evaporator with a high-efficiency defrosting function, including a mounting frame and a protective frame disposed on the side wall of the mounting frame. The evaporator body is disposed inside the mounting frame. A screw is rotatably disposed on one inner wall of the mounting frame. One end of the screw extends to the outside of the mounting frame and is provided with a second synchronous pulley. A cleaning brush is threadedly connected to the outside of the screw. A soft brush that contacts the evaporator body is disposed on one side of the cleaning brush. An outlet pipe for transporting hot air and heating the evaporator body is disposed on the side wall of the cleaning brush. An inlet pipe is connected inside the outlet pipe. One end of the inlet pipe extends to the outside of the mounting frame.

[0007] Preferably, the rear end of the cleaning brush is provided with symmetrical limiting blocks, and the inner wall of the mounting frame is provided with limiting grooves for the limiting blocks to move.

[0008] Preferably, the mounting frame is further provided with a water collection frame for collecting frost water, and the top of the water collection frame is provided with a guide plate for guiding the frost water. The inside of the water collection frame is connected to a drain pipe, and one end of the drain pipe extends to the outside of the mounting frame.

[0009] Preferably, a rotating rod is rotatably provided inside the water collection frame, one end of the rotating rod extends to the outside of the water collection frame and is provided with a first synchronous wheel, and multiple ice-breaking rods are provided on the outside of the rotating rod.

[0010] Preferably, a motor is installed inside the protective frame, and the output shaft of the motor is connected to one end of the screw via a coupling.

[0011] Preferably, the first and second synchronous pulleys are connected by a synchronous belt drive.

[0012] The advantages of this utility model compared to the prior art are:

[0013] By using an external heating device in conjunction with the air inlet pipe, hot air is transported to the inside of the air outlet pipe and then sprayed out from the nozzle inside the air outlet pipe. The hot air can melt the frost on the surface of the evaporator body. At the same time, the motor is started to drive the screw to rotate, so that the cleaning brush on the outside of the screw can reciprocate, thereby quickly and efficiently removing the frost on the surface of the evaporator body and speeding up the defrosting efficiency.

[0014] The motor works in conjunction with the second synchronous pulley and synchronous belt to drive the first synchronous belt 11 and the rotating rod to rotate, which in turn causes the crushing rod outside the rotating rod to rotate. The crushing rod can be used to crush the frost that has condensed into lumps, and then the frost water is discharged outside the water collection frame. Attached Figure Description

Detailed Implementation

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model provides:

[0024] A finned evaporator with a high-efficiency defrosting function includes a mounting frame 1 and a protective frame 3 disposed on the side wall of the mounting frame 1. An evaporator body 2 is disposed inside the mounting frame 1. A screw 12 is rotatably disposed on the inner wall of one side of the mounting frame 1. One end of the screw 12 extends to the outside of the mounting frame 1 and is provided with a second synchronous wheel 14. A cleaning brush 7 is threadedly connected to the outside of the screw 12. A soft brush is disposed on one side of the cleaning brush 7 that contacts the evaporator body 2. An exhaust pipe 8 is disposed on the side wall of the cleaning brush 7 for transporting hot air and heating the evaporator body 2. An exhaust pipe 5 is connected inside the exhaust pipe 8. One end of the exhaust pipe 5 extends to the outside of the mounting frame 1.

[0025] By using an external heating device in conjunction with the air inlet pipe 5, hot air is transported to the interior of the air outlet pipe 8 and then sprayed out from the nozzle inside the air outlet pipe 8. The hot air can melt the frost on the surface of the evaporator body 2, thereby quickly and efficiently removing the frost from the surface of the evaporator body 2 and improving the defrosting efficiency.

[0026] like Figure 5 and Figure 4 As shown, the rear end of the cleaning brush 7 is provided with symmetrical limiting blocks 13, and the inner wall of the mounting frame 1 is provided with a limiting groove for the limiting blocks 13 to move.

[0027] By using the limiting block 13 to slide within the limiting groove, the position of the cleaning brush 7 can be effectively prevented from shifting during movement, thus ensuring that the cleaning brush 7 can accurately defrost the evaporator body 2 and avoiding the problem of poor defrosting effect caused by positional deviation.

[0028] like Figure 5 As shown, the interior of the mounting frame 1 is also provided with a water collection frame 4 for collecting frost water. The top of the water collection frame 4 is provided with a guide plate 15 for guiding the frost water. The interior of the water collection frame 4 is connected to a drain pipe 6, and one end of the drain pipe 6 extends to the outside of the mounting frame 1.

[0029] The water collection frame 4 effectively collects frost water that falls from the air, as well as frost that has condensed into clumps. This prevents frost water from flowing around and seeping into the interior of the evaporator body 2. Frost water can negatively impact the normal operation of the equipment, leading to a reduction in the power of the evaporator body 2, and thus affecting the efficiency and performance of the entire refrigeration system.

[0030] like Figure 6 As shown, a rotating rod 16 is rotatably installed inside the water collection frame 4. One end of the rotating rod 16 extends to the outside of the water collection frame 4 and is equipped with a first synchronous wheel 11. Multiple ice-breaking rods 17 are installed on the outside of the rotating rod 16.

[0031] By using the rotating rod 16 to drive the crushing rod 17 to rotate, the crushing rod 17 can effectively break up the frost that has solidified into lumps. After processing, the broken frost and frost water will be discharged together and eventually flow to the outer area of ​​the water collection frame 4.

[0032] like Figure 3 As shown, a motor 9 is installed inside the protective frame 3, and the output shaft of the motor 9 is connected to one end of the screw 12 via a coupling.

[0033] By simultaneously starting the motor 9, the screw 12 is driven to rotate, which enables the cleaning brush 7 on the outside of the screw 12 to reciprocate. This allows for a comprehensive defrosting of the evaporator body 2, ensuring that it maintains high-efficiency heat exchange performance during operation.

[0034] like Figure 3 As shown, the first synchronous pulley 11 and the second synchronous pulley 14 are connected by a synchronous belt 10.

[0035] The motor 9 works in conjunction with the second synchronous pulley 14 and the synchronous belt 10 to drive the first synchronous pulley 11 and the rotating rod 16 to rotate. The synchronous belt 10 can drive the first synchronous pulley 11 and the second synchronous pulley 14 to rotate simultaneously, reducing energy consumption.

[0036] When defrosting of the evaporator body 2 is required, external heating equipment works in conjunction with the air inlet pipe 5 to transport hot air to the inside of the air outlet pipe 8, and then sprays it out from the nozzle inside the air outlet pipe 8. The hot air can melt the frost on the surface of the evaporator body 2. At the same time, the motor 9 is started to drive the screw 12 to rotate, so that the cleaning brush 7 on the outside of the screw 12 can reciprocate, thereby quickly and efficiently removing the frost on the surface of the evaporator body 2 and speeding up the defrosting efficiency. During the defrosting process, the frost water and some frost clumps will fall into the inside of the water collection frame 4. At the same time, the motor 9 works in conjunction with the second synchronous pulley 14 and the synchronous belt 10 to drive the first synchronous pulley 11 and the rotating rod 16 to rotate, so that the crushing rod 17 on the outside of the rotating rod 16 will also rotate. The crushing rod 17 can break up the frost clumps, and then discharge them to the outside of the water collection frame 4 along with the frost water.

[0037] The above embodiments merely illustrate one or several implementations of a finned evaporator with a high-efficiency defrosting function according to this utility model.
