Description

Technical Field

[0001] This utility model relates to the technical field of air cooler equipment, and in particular to a refrigeration air cooler. Background Technology

[0002] As an important branch of refrigeration equipment, evaporative air coolers can be divided into two main types based on their application scenarios: industrial and residential. Industrial evaporative air coolers primarily serve low-temperature storage environments and cold chain transportation, while residential models are often referred to as water-cooled air conditioners. From a mechanical perspective, the core components of a typical evaporative air cooler include a refrigeration unit and an airflow guiding mechanism. After the refrigeration unit mechanically lowers the air temperature, the guiding mechanism delivers the cooled airflow to the target space, thus achieving the function of regulating the ambient temperature.

[0003] During the mechanical operation of the refrigeration unit, the coil assembly and the matching heat sink fins work together to cool the air. When the equipment is running continuously, frost will gradually form on the surface of the heat sink fins due to the temperature difference. The continuous accumulation of this frost between the fins will lead to two mechanical problems: first, the frost accumulation will physically block the airflow path between the fins; second, the reduction in the cross-sectional area of ​​the airflow channel will directly weaken the air delivery efficiency of the equipment. The essence of this phenomenon is the problem of unavoidable physical frost formation and mechanical structural interference under low-temperature conditions. Utility Model Content

[0004] The purpose of this invention is to provide a refrigeration air cooler that can defrost the fins.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a refrigeration air cooler, comprising: a housing, a fan disposed on the housing, and a condenser with fins disposed inside the housing.

[0006] Two push plates are slidably connected to the inner wall of the housing. The push plates are driven to move closer to each other by a drive mechanism, which is located on the housing and connected to the push plates.

[0007] Both push plates are oscillatingly connected with several discharge plates, wherein the discharge plates between two adjacent push plates are rotatably connected in the middle, and the rotatable end between the two discharge plates can be pushed out to the end away from the fins.

[0008] Preferably, a storage box is fixedly connected inside the housing, and a feed pipe is connected to the storage box, with a guide frame fixedly connected to the feed pipe.

[0009] Preferably, a heating wire is fixedly connected inside the guide frame, and a temperature-conducting plate is fixedly connected on the guide frame, with the temperature-conducting plate in contact with the heating wire.

[0010] Preferably, a filter screen is fixedly connected inside the guide frame, and the filter screen is located above the feed pipe.

A liquid pump is fixedly connected inside the storage tank, and the liquid pump is connected to the storage tank through a pipe.

[0012] Preferably, a second liquid pump is fixedly connected inside the circulation tank, and the second liquid pump is connected to the nozzle through a pipe.

[0013] Preferably, a slide rail is fixedly connected inside the housing, a T-shaped slider is fixedly connected to the push plate, the slider is slidably connected to the slide rail, and the T-shaped block is fixedly connected to the push plate.

[0014] Preferably, the drive mechanism includes a bidirectional lead screw rotatably connected to the housing and a motor fixedly connected to the housing, wherein the output shaft of the motor is fixedly connected to the bidirectional lead screw, and the bidirectional lead screw is threadedly connected to the push plate.

[0025] like Figures 1 to 3 A refrigeration air cooler 2 includes: a housing 1, a fan 2 disposed on the housing 1, and a condenser 4 disposed inside the housing 1 and having fins 3. The condenser 4 includes fins 3 and condenser tubes, wherein the condenser tubes are fixedly connected to the fins 3 and extend to the outside of the fins 3 at both ends for transmitting refrigerant to cool the fins 3 (the condenser tubes are not labeled in the figure).

[0026] This utility model also includes: a push plate 5, a drive mechanism 6, and a discharge plate 7;

[0027] Two push plates 5 are slidably connected to the inner wall of the housing 1. The push plates 5 are driven to move closer to each other by a drive mechanism 6, which is located on the housing 1 and connected to the push plates 5. Several discharge plates 7 are oscillatingly connected to both push plates 5. The discharge plates 7 between two adjacent push plates 5 are rotatably connected in the middle, and the rotatable ends between the two discharge plates 7 can be pushed away from the fin 3. The drive mechanism 6 includes a bidirectional lead screw 21 rotatably connected to the housing 1 and a motor 22 fixedly connected to the housing 1. The output shaft of the motor 22 is fixedly connected to the bidirectional lead screw 21, and the bidirectional lead screw 21 is threadedly connected to the push plates 5. The motor 22 drives the bidirectional lead screw 21 to rotate, causing the bidirectional lead screw 21 to drive the push plates 5 to move relative to each other during the rotation. At this time, the two discharge plates 7 rotate and push the frost off the fin 3, thereby defrosting the fin 3 in advance and reducing the frost residue on the fin 3.

[0028] Specifically, a storage tank 8 is fixedly connected inside the housing 1. A feed pipe 9 is connected to the storage tank 8. A guide frame 10 is fixedly connected to the feed pipe 9. A heating wire 11 is fixedly connected inside the guide frame 10. A temperature-conducting plate 12 is fixedly connected to the guide frame 10. The temperature-conducting plate 12 is in contact with the heating wire 11. A filter screen 14 is fixedly connected inside the guide frame 10. The filter screen 14 is located above the feed pipe 9. Therefore, frost will enter the guide frame 10. The heating wire 11 is activated and conducts heat to the temperature-conducting plate 12. After the temperature-conducting plate 12 conducts heat, it heats the frost. After being heated, the frost becomes liquid and passes through the filter screen 14 into the storage tank 8 for storage, thereby realizing water collection and reducing water waste.

[0029] Specifically, a circulation tank 15 is fixedly connected to the housing 1, and several nozzles 16 are fixedly connected to the housing 1. The nozzles 16 are aligned with the fins 3. A first pump 17 is fixedly connected to the storage tank 8 and is connected to the storage tank 8 through a pipe. A second pump 18 is fixedly connected to the circulation tank 15 and is connected to the nozzles 16 through a pipe. When the water in the storage tank 8 is collected, the first pump 17 is started, and the first pump 17 draws water from the storage tank 8 into the circulation tank 15. The second pump 18 is started, and the second pump 18 draws water from the circulation tank 15 into the nozzles 16, so that the nozzles 16 can transfer water to defrost the fins 3.

[0030] Specifically, a slide rail 19 is fixedly connected inside the housing 1, and a T-shaped slider 20 is fixedly connected to the push plate 5. The slider is slidably connected to the slide rail 19, and the T-shaped block is fixedly connected to the push plate 5. The slide rail 19 is used to support the T-shaped slider 20 and the push plate 5, and at the same time, it can prevent the push plate 5 from rotating.

[0031] Specifically, a limit block 23 is provided on the slide rail 19, and several horizontally distributed threaded holes 24 are provided on the slide rail 19. A bolt 25 is rotatably connected to the limit block 23. The bolt 25 is threadedly connected to the threaded hole 24. The limit block 23 is in contact with the T-block, thereby limiting the movement position of the T-block.

[0032] The principle of this invention is as follows: After the air cooler 2 is started, the fan 2 drives the airflow through the interior of the housing 1. The refrigerant in the condenser tube continues to circulate, causing the surface temperature of the fins 3 to decrease and form a condensation layer. When the frost layer accumulates to a certain thickness, the motor 22 drives the bidirectional lead screw 21 to rotate, forcing the two push plates 5 to slide towards each other along the slide rail 19. When the push plates 5 move, they drive the hinged discharge plates 7 to move in conjunction: the rotating ends of the adjacent discharge plates 7 unfold outward, forming an angled structure similar to a scraper, which peels off the frost layer from the surface of the fins 3 in one piece.

[0033] The scraped frost falls along the guide frame 10 into the feed pipe 9, and melts into liquid water after contacting the temperature-conducting plate 12 heated by the heating wire 11. After being filtered through a filter screen, the liquid is stored in a water tank. When secondary defrosting is required, the first pump 17 transports the water from the water tank to the circulation tank 15, and the second pump 18 then sprays the water evenly onto the surface of the fins 3 through the nozzle 16, using the temperature difference between the water and the frost layer to accelerate the defrosting process.

[0034] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
