Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and more specifically, to an air cooler. Background Technology

[0002] Water-cooled air coolers typically have air inlets on their sides, with water curtain components embedded within. These components are covered with water curtain paper, which can rot or perforate over time, requiring periodic replacement. However, this replacement process is cumbersome and the overall performance is unsatisfactory. Therefore, this invention proposes an air cooler. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an air cooler with excellent cooling effect and low maintenance cost.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The air cooler involved in this utility model includes a box with an air outlet at the top, an axial flow fan near the air outlet inside the box, an air inlet on at least one side of the box, and a water curtain assembly on the box on the inner side of the air inlet.

[0005] The water curtain assembly includes a water distribution pipe located above the air inlet and a water receiving trough located below the air inlet. A support pipe parallel to the water distribution pipe is provided in the water receiving trough. Several connecting rods are arranged at intervals along the length direction between the support pipe and the water distribution pipe. Cotton ropes are spirally wound on the connecting rods. Several nozzles arranged at intervals along the axial direction and spraying downwards are provided on the water distribution pipe.

[0006] The present invention is further configured such that: one end of the connecting rod is connected to an upper pipe clamp fitted on the water distribution pipe, and the other end is connected to a lower pipe clamp fitted on the support pipe.

[0007] The present invention is further configured such that at least one nozzle is provided between two adjacent connecting rods.

[0008] The present invention is further configured such that: one end of the water distribution pipe is provided with a plug, and the other end is connected in series with a water pipe between it and the water receiving tank, and a circulation pump is connected in series on the water pipe.

[0009] The present invention is further configured such that the water distribution pipe is arranged horizontally.

[0010] In summary, the present invention has the following beneficial effects: The air cooler involved in the present invention arranges several vertically arranged connecting rods in the air inlet, and the connecting rods are wrapped with continuously moistened cotton ropes. After the air passes through the adjacent connecting rods, it can be cooled down quickly to achieve the air cooling function. The cotton ropes do not rot when wet, have a long service life, low maintenance costs, complete overall functions, and strong practicality. Attached Figure Description

[0013] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See Figure 1 and Figure 2 As shown, an air cooler involved in this embodiment includes a housing 2 with an air outlet 1 on the top, an axial flow fan 3 located inside the housing 2 near the air outlet, an air inlet 4 on at least one side of the housing 2, and a water curtain assembly 100 installed on the housing on the inner side of the air inlet 4.

[0017] The water curtain assembly 100 includes a water distribution pipe 5 located above the air inlet and a water receiving trough 6 located below the air inlet. The water receiving trough 6 contains a support pipe 7 that is parallel to the water distribution pipe. A plurality of connecting rods 8 are arranged at intervals along the length direction between the support pipe 7 and the water distribution pipe 5. Cotton ropes 9 are spirally wound on the connecting rods 8. A plurality of nozzles 10 are arranged at intervals along the axial direction and spray downwards on the water distribution pipe 5.

[0018] Furthermore, at least one nozzle 10 is provided between two adjacent connecting rods 8.

[0019] Furthermore, one end of the water distribution pipe 5 is provided with a plug 13, and the other end is connected in series with a water pipe 14 between it and the water receiving tank. A circulation pump (not shown) is connected in series on the water pipe 14.

[0020] Furthermore, the water distribution pipe 5 is arranged horizontally.

[0021] In this implementation scheme, a circulating pump is used to achieve water outlet at the top and water inlet at the bottom of water pipe 14. Nozzle 10 sprays water, wetting cotton rope 9. Axial flow fan 3 operates, providing negative pressure inside the housing 2, causing the air passing through the two adjacent connecting rods 8 to be rapidly cooled, thus achieving the cooling air output from air outlet 1. Water seeping from the bottom of the cotton rope 9 on each connecting rod 8 is collected in water tank 6 and then flows into water pipe 14 for circulation (because water will be lost, water tank 6 needs to be replenished periodically).

[0022] Example 2

[0023] See Figure 1 and Figure 2 As shown, the air cooler involved in this embodiment is further configured, based on embodiment 1, with one end of the connecting rod 8 connected to an upper pipe clamp 11 sleeved on the water distribution pipe and the other end connected to a lower pipe clamp 12 sleeved on the support pipe.

[0024] In this embodiment, by setting an upper pipe clamp 11 connected to the water distribution pipe at one end of the connecting rod 8 and a lower pipe clamp 12 connected to the support pipe at the other end, it is more convenient to connect the connecting rod 8 to the water distribution pipe and the support pipe.

[0025] The air cooler involved in this utility model has several vertically arranged connecting rods in the air inlet, and cotton ropes that are continuously moistened are wound on the connecting rods. After the air passes through the adjacent connecting rods, it can be cooled down quickly to achieve the air cooling function. The cotton ropes do not rot when wet, have a long service life, low maintenance costs, complete functions, and strong practicality.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe orientation or positional relationships in this utility model are for illustrative purposes only and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood in conjunction with the embodiments and according to the specific circumstances.
