[0036] The evaporative cooler is a new type of cooling equipment that organically combines the sprinkler-type drain pipe cooler and the circulating cooling tower, integrating the advantages of both. The cooler adopts a countercurrent structure, which mainly includes a fan, a box, a water tray, a cooling heat exchange tube group, a steel structure frame, a wind screen, a circulating water pump, a float valve, etc. The cooling tubes are used in parallel, with a large heat exchange area and a small system resistance. The structure is compact and occupies a small area. Modular design, independent unit operation, can be arbitrarily increased or adjusted according to the system production capacity. Due to the above advantages, evaporative cooling units are increasingly favored in commercial occasions with limited space. However, the refrigerant pipelines of the cooling heat exchange tube group of the traditional evaporative cooling unit and the circulating water circuit where the circulating water pump is located are respectively arranged on both sides of the evaporative cooler, so that there is a large amount of unused space on both sides of the evaporative cooler, and the volume of the cooling heat exchange tube group is reduced, resulting in the problem that the evaporative cooler occupies a large space and has low heat exchange efficiency. To this end, the present application provides a method such as Figures 1 to 5 The heat exchange assembly shown includes: a frame 1; a heat exchange tube group 2, the heat exchange tube group 2 is arranged in the frame 1, and a refrigerant pipeline for communicating with a preset structure is arranged on the first side of the heat exchange tube group 2; a spray mechanism 3, the spray mechanism 3 is arranged in the frame 1, and the spray mechanism 3 is located above the heat exchange tube group 2; a water receiving pan 4, the water receiving pan 4 is arranged in the frame 1, and the water receiving pan 4 is located below the heat exchange tube group 2; a circulating water circuit 5, the circulating water circuit 5 is arranged in the frame 1, and the spray mechanism 3 is connected to the water receiving pan 4 through the circulating water circuit 5; the circulating water circuit 5 is located on the first side of the heat exchange tube group 2, and the circulating water circuit 5 and the refrigerant pipeline are staggered. The refrigerant pipeline and the circulating water circuit 5 are both arranged on the first side of the heat exchange tube group 2, and the refrigerant pipeline and the circulating water circuit 5 are staggered, so that the refrigerant pipeline and the circulating water circuit 5 can only occupy the length of the first side of the heat exchange tube group 2, while the part of the heat exchange tube group 2 opposite to the first side can increase the volume because no pipeline is set, which overcomes the problem of space waste caused by the need to respectively arrange the refrigerant pipeline and the circulating water circuit 5 on both sides of the evaporative cooler in the prior art, reduces the space occupied by the refrigerant pipeline and the circulating water circuit 5 in the frame 1, effectively increases the volume of the heat exchange tube group 2, thereby increasing the heat exchange capacity of the heat exchange tube group 2, and achieves the purpose of effectively improving the heat exchange efficiency of the heat exchange component under the condition of the same occupied space.

[0037] As an embodiment, the refrigerant pipeline includes a refrigerant distribution pipe 61, which is located obliquely above the first side of the heat exchange tube group 2, and there is a horizontal spacing and a vertical spacing between the refrigerant distribution pipe 61 and the heat exchange tube group 2, and the circulating water circuit 5 is located below the refrigerant distribution pipe 61, and the circulating water circuit 5 is connected to the spray mechanism 3 through the vertical spacing. There is a spacing between the heat exchange tube group 2 and the frame 1 in the horizontal direction. At this time, the refrigerant distribution pipe 61 can be set within this spacing, and the height of the refrigerant distribution pipe 61 is higher than the heat exchange tube group 2. At this time, there is an avoidance space between the first side of the heat exchange tube group 2 and the frame 1, and the circulating water channel 5 can be installed in the avoidance space, thereby achieving the purpose of the refrigerant pipeline and the circulating water channel 5 being on the same side of the heat exchange tube group 2. At this time, only the refrigerant distribution pipe 61 occupies the upper space with a vertical spacing dimension, and the pillars constituting the frame 1 have a certain width and the crossbeams have a certain height. The size of the refrigerant distribution pipe 61 can be fully accommodated and avoided by utilizing the height of the crossbeam, so there is no need to adjust the size of the frame 1, and the purpose of the refrigerant pipeline and the circulating water channel 5 being on the same side of the heat exchange tube group 2 can be achieved.

[0038] The circulating water circuit 5 has a water dividing pipe 51 and a plurality of water dividing branch pipes 52. The water dividing pipe 51 is located below the refrigerant dividing pipe 61, and the water dividing branch pipe 52 is connected to the spray mechanism 3 through the vertical spacing. The water in the circulating water circuit 5 is divided into a plurality of branches by the water dividing branch pipe 52, and then respectively sent into different spray pipes in the spray mechanism 3, thereby increasing the spray effect on the heat exchange tube group 2. At the same time, the diameter of the water dividing branch pipe 52 is much smaller than the diameter of the water dividing pipe 51, so that the water dividing branch pipe 52 can be smoothly connected to the spray mechanism 3 through the vertical spacing, thereby ensuring reliable connection between the circulating water circuit 5 and the spray mechanism 3.

[0039] The refrigerant pipeline also includes a refrigerant liquid branch pipe 62, through which the refrigerant liquid branch pipe 61 is connected to the heat exchange tube group 2, and the refrigerant liquid branch pipe 62 is staggered with the water liquid branch pipe 52. The refrigerant is divided into multiple branches by the refrigerant liquid branch pipe 62, and is evenly fed into different pipes of the heat exchange pipeline, which effectively improves the heat exchange efficiency of the heat exchange tube group 2. At the same time, the diameter of the refrigerant liquid branch pipe 62 is small, and there is a certain gap between adjacent refrigerant liquid branch pipes 62. The water liquid branch pipe 52 can pass through this gap, realizing the staggered setting between the water liquid branch pipe 52 and the gas branch, and ensuring the reliable connection between the refrigerant liquid branch pipe 61 and the heat exchange tube group 2, and the water liquid branch pipe 51 and the spray mechanism 3.

[0040] As shown in the figure, the refrigerant liquid separation branch pipe 62 and the water liquid separation branch pipe 52 are both L-shaped, and the lower end of the water liquid separation branch pipe 52 is connected to the water liquid separation pipe 51, and the horizontal end faces the inside of the frame 1 to connect with the spray mechanism 3, and the upper end of the refrigerant liquid separation branch pipe 62 is connected to the refrigerant liquid separation pipe 61, and the horizontal end faces the inside of the frame 1 to connect with the heat exchange tube group 2.

[0041] The refrigerant pipeline includes a collecting pipe 63, and the collecting pipe 63 is located below the heat exchange tube group 2, and the circulating water circuit 5 is located between the collecting pipe 63 and the frame 1. The collecting pipe 63 is used to collect the liquid refrigerant generated in the heat exchange tube group 2 and send it to the preset structure. At this time, the collecting pipe 63 is set below the heat exchange tube group 2. The collecting pipe 63 will not occupy the space between the heat exchange tube group 2 and the frame 1, thereby ensuring that the circulating water circuit 5 can be reliably installed on the first side of the heat exchange tube group 2 without interfering with the collecting pipe 63, thereby ensuring the reliability of the heat exchange component. The pillars constituting the frame 1 have a certain width and the crossbeams have a certain height. The size of the collecting pipe 63 can be completely accommodated and avoided by utilizing the height of the crossbeam, so there is no need to adjust the size of the frame 1, and the purpose of the refrigerant pipeline and the circulating water circuit 5 being on the same side of the heat exchange tube group 2 can be achieved.

[0042] The heat exchange assembly also includes a water pump 7, which is arranged in the frame 1 and located on the first side of the frame 1. The water inlet of the water pump 7 is connected to the water receiving tray 4, and the water outlet of the water pump 7 is connected to the circulating water circuit 5. The water pump 7 in the water receiving tray 4 is used to send the water to the circulating water circuit 5, thereby realizing the recycling of water. The water pump 7 uses a small-volume water pump 7, which saves space and provides enough space for the water receiving tray 4 to be enlarged. Since the water pump 7 is small in size and can be arranged on one side of the water receiving tray 4, the lower end of the circulating water circuit 5 can be connected to the water pump 7 through a vertical straight pipe, avoiding the need to use a curved pipe routing method due to the large volume of the pump body in the prior art, thereby ensuring reliable water circulation. In addition, the water pump 7 is arranged inside the frame 1, and a side panel is arranged outside the frame 1 for shielding, thereby effectively improving the appearance of the heat exchange assembly.

[0043] The heat exchange component also includes a packing structure 8, which is arranged in the frame 1, and the packing structure 8 is located between the heat exchange tube group 2 and the water receiving tray 4. The packing structure 8 enables the water sprayed by the spray mechanism 3 to exchange heat with the air, thereby improving the heat exchange efficiency of the heat exchange component. The number of the packing structures 8 can be one, or two or more. When there are two or more packing structures 8, all the packing structures 8 are arranged in parallel in the vertical direction between the heat exchange tube group 2 and the water receiving tray 4. The packing structure 8 is detachable, so that the packing structure 8 can be matched and combined according to different heat exchange requirements, thereby improving the application range of the heat exchange component.

[0044] The heat exchange component also includes an air inlet panel 9, which is arranged on the side of the frame 1, and the filler structure 8, the water tray 4 and the air inlet panel 9 together form an air inlet cavity 11, and the air inlet panel 9 is provided with an air inlet port connected to the air inlet cavity 11. The air inlet panel 9 is used to shield the frame 1 and its internal structure to improve the appearance of the heat exchange component. The frame 1 has at least four side surfaces, and the orientations of the four side surfaces are different. At the position corresponding to the air inlet cavity 11, at least one air inlet panel 9 is provided on each side surface. By returning air through the air inlet panels 9 on multiple sides, the air volume of the heat exchange component can be effectively increased, thereby increasing the heat exchange amount and ultimately improving the heat exchange efficiency of the heat exchange component.

[0045] The heat exchange assembly further includes a fan 10, which is disposed on the frame 1 and is located above the spray mechanism 3. The fan 10 is used to generate negative pressure on the top of the frame 1, forcing external air to enter the air inlet cavity 11 from multiple sides of the frame 1, and then pass through the packing structure 8, the heat exchange tube group 2 and the fan 10 in sequence before being discharged from the heat exchange assembly, thereby ensuring the heat exchange efficiency of the packing structure 8 and the heat exchange tube group 2.

[0046] When the heat exchange component is working, the refrigerant liquid flows in from the refrigerant liquid distribution pipe 61, and flows into the heat exchange tube group 2 through the refrigerant liquid distribution branch pipe 62 for heat exchange. After the heat exchange is completed, it flows out from the collecting pipe 63 to complete the refrigerant circulation. The water pump 7 sends the water in the water receiving tray 4 to the circulating water circuit 5, and sends it to the spray mechanism 3 through the water distribution pipe 51 and the water distribution branch pipe 52. The spray mechanism 3 sprays water onto the heat exchange tube group 2. The water is left in the form of a film on the surface of the heat exchange tube of the heat exchange tube group 2, and then flows into the receiving tube after heat exchange through the packing structure 8. The water circulation is completed in the water tray 4; the fan 10 works to introduce the external gas into the air inlet chamber 11 from all sides of the frame 1, and under the negative pressure of the fan 10, the gas passes through the packing structure 8 and the heat exchange tube group 2 in sequence and is discharged through the fan 10 to complete the gas circulation; wherein, the water and the refrigerant exchange heat at the outlet of the heat exchange tube group 2, and the refrigerant is cooled by the latent heat of evaporation of the water, and then the gas circulation takes away the water vapor generated during the evaporation of the water, ensuring that the water forms a continuous water film on the surface of the heat exchange tube of the heat exchange tube group 2, thereby improving the heat exchange efficiency.

[0047] The frame 1 includes a water tray support frame 12, a filler installation frame 13 and a heat exchange tube group installation frame stacked in sequence from bottom to top, the water tray 4 is arranged on the water tray support frame 12, and the lower end of the water tray support frame 12 constitutes the bottom of the frame 1, and the filler installation frame 13 is installed on the water tray support frame 12 for installing the filler structure 8. Figure 6 and Figure 7As shown, the support height of the water tray support frame 12 is greater than the height of the water tray 4, so that a certain space is formed between the upper part of the water tray 4 and the lower part of the filler structure 8, and this space constitutes the air inlet cavity 11. Figure 1 It can be seen that an air inlet panel 9 is arranged on the frame between the water tray 4 and the packing structure 8, and air inlet panels 9 are arranged on multiple sides of the frame 1 where the air inlet cavity 11 is located, so that the gas can flow into the air inlet cavity 11 from multiple sides of the frame, effectively improving the air volume of the heat exchange component; the heat exchange tube group installation frame is arranged on the packing installation frame 13, which is used to install the heat exchange tube group 2, wherein the crossbeam between the heat exchange tube group installation frame and the packing installation frame 13 has a certain thickness, and this thickness can just offset the size of the collecting pipe 63, thereby ensuring the reliable installation of the heat exchange tube group 2 and the refrigerant pipeline. The top surface of the frame 1 is formed above the heat exchange tube group installation frame, and the top surface is used to set the fan 10 and other electronic components.

[0048] An evaporative cooler comprises the above-mentioned heat exchange component.
