Description

Technical Field

[0001] The utility model relates to the technical field of air guide covers, in particular to a cooling tower heat exchanger. Background Art

[0002] The air guide is an important part of the cooling system. It can guide the air flow so that the air can flow through the radiator more concentratedly. With the help of the air guide, the air flow path is clearer, which can reduce the resistance of air flow, improve the ventilation effect of the radiator, and increase the heat dissipation capacity of the radiator.

[0003] The more air that flows through the radiator, the better the heat dissipation effect. However, dust and other debris in the air will accumulate on the radiator. The accumulated dust will reduce the air flow rate, hinder heat exchange, and affect the heat dissipation efficiency. Among them, the inner side of the radiator close to the air guide cover is difficult to clean, and the radiator usually needs to be removed for cleaning. Frequent disassembly will increase the wear of parts and reduce the stability of the device. The disassembly and cleaning process will also interrupt the heat dissipation, affecting the heat dissipation efficiency. Utility Model Content

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] In order to more clearly describe the structure of the cooling tower heat exchanger, the present invention defines the terms "distal end" and "proximal end". Specifically, the "distal end" refers to the end away from the air inlet, and the "proximal end" refers to the end close to the air inlet. Figure 1 For example, Figure 1 The end of the middle vertical side plate 32 close to the top plate 34 is the distal end. Figure 1 The end of the middle vertical side plate 32 close to the mounting frame 1 is the proximal end.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3A cooling tower heat exchanger includes a mounting frame 1, a cleaning mechanism 2 and an air guide 3, wherein the distal end and the proximal end of the mounting frame 1 are open, and a heat dissipation mechanism (not shown in the figure) is installed in the mounting frame 1. The air guide 3 is arranged at the distal end of the mounting frame 1, the side of the air guide 3 is sealed, the proximal end opening of the air guide 3 is connected to the mounting frame 1, and an air outlet 341 is opened at the distal end of the air guide 3. The cleaning mechanism 2 is arranged between the mounting frame 1 and the air guide 3, and the cleaning mechanism 2 includes a horizontally arranged screw 22, a cleaning rod 24 threadedly connected to the screw 22, and a plurality of bristles 25 are arranged at the proximal end of the cleaning rod 24. Specifically, the cleaning rod 24 is threadedly connected to the screw 22 through a slider 23. The screw 22 in the cleaning mechanism 2 is rotated to drive the cleaning rod 24 to move along the screw 22, so that the cleaning rod 24 cleans the distal end of the heat dissipation mechanism, and the heat dissipation mechanism can be cleaned without disassembly, thereby simplifying the cleaning steps and improving the heat dissipation efficiency.

[0032] The specific structure of the screw rod 22 and the mounting bracket 1 is described below:

[0033] Please refer to Figure 2 The screw 22 is connected to the drive motor 21. Specifically, the output end of the drive motor 21 is connected to the screw 22 through a coupling 211. The rotation of the screw 22 can be controlled by controlling the output of the drive motor 21.

[0034] Please refer to Figure 2 On the opposite side of the interior of the mounting frame 1, a plurality of pipe interfaces 11 are provided. Specifically, the heat dissipation mechanism may be a plurality of fin tubes arranged in parallel, cooling liquid is passed into the tubes, and the tube openings of the fin tubes are connected to the pipe interfaces 11. When air flows through the heat dissipation mechanism, the heat in the air is taken away by the cooling liquid in the fin tubes.

[0035] Please refer to Figure 1 A sealing frame 12 is provided at the proximal end of the mounting frame 1. Specifically, when the mounting frame 1 is provided on the surface of a heating device (not shown in the figure), the sealing frame 12 is connected to the heating device by bolts (not shown in the figure) to ensure the air tightness between the mounting frame 1 and the heating device, so that the air flow path is more clear and the ventilation effect is ensured.

[0036] The specific structure of the air guide portion 3 is described below:

[0037] Please refer to Figure 1 and Figure 3The air guide 3 includes an inclined side panel 31, a vertical side panel 32 and a top panel 34, wherein the inclined side panel 31 is arranged obliquely. The vertical side panel 32 is arranged vertically, and a plurality of inclined side panels 31 and vertical side panels 32 are connected in an annular manner end to end and arranged at intervals. The top panel 34 is arranged at the far end of the vertical side panel 32 and the inclined side panel 31, and the top panel 34 simultaneously connects a plurality of inclined side panels 31 and the vertical side panels 32, and an air outlet 341 is provided on the top panel 34. Specifically, the inclined side panel 31 is inclined toward the air outlet 341, guiding the air to flow out evenly from the air outlet 341, reducing the resistance of air flow, and ensuring the ventilation effect.

[0038] Please refer to Figure 1 and Figure 3 The air guide 3 further includes a triangular plate 33, which is disposed at the connection between the inclined side plate 31, the vertical side plate 32 and the top plate 34, and the triangular plate 33 simultaneously connects the inclined side plate 31, the vertical side plate 32 and the top plate 34. Specifically, the triangular plate 33 eliminates the dead angle between the inclined side plate 31, the vertical side plate 32 and the top plate 34, guides the air to flow evenly toward the air outlet 341 and then flows out of the air guide 3, reduces the resistance of air flow, improves the ventilation effect of the radiator, and increases the heat dissipation capacity of the radiator.

[0039] Please refer to Figure 1 The vertical side plate 32 is provided with a through hole 322 and an inspection plate 321, and the inspection plate 321 covers the through hole 322 and is connected to the vertical side plate 32. Specifically, when inspecting and maintaining the cleaning mechanism 2, the inspection plate 321 can be removed, and there is no need for personnel to dismantle the entire air guide part 3, thereby ensuring the inspection efficiency.

[0040] The specific working process of the utility model is as follows:

[0041] When cleaning the distal end of the heat dissipation mechanism, the operator starts the drive motor 21, and the drive motor 21 drives the screw 22 to rotate clockwise and counterclockwise, so that the cleaning rod 24 reciprocates along the screw 22. During the movement of the cleaning rod 24, the bristles 25 clean the distal end of the heat dissipation mechanism.

[0042] When maintaining the heat dissipation mechanism, personnel can remove the inspection plate 321 and perform maintenance through the through hole 322 .

[0043] It can be seen that the above cooling tower heat exchanger is provided with a cleaning mechanism 2 between the mounting frame 1 and the air guide 3. The screw 22 in the cleaning mechanism 2 is rotated to drive the cleaning rod 24 to move along the screw 22, so that the cleaning rod 24 cleans the far end of the heat dissipation mechanism, and the heat dissipation mechanism can be cleaned without disassembling the heat dissipation mechanism, thereby simplifying the cleaning steps and improving the heat dissipation efficiency.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
