Description

Technical Field

[0001] This utility model relates to the field of evaporative condenser technology, specifically a compact multi-stage evaporative condenser. Background Technology

[0002] An evaporative condenser is a high-efficiency and energy-saving cooling device that integrates water cooling and air cooling, as well as heat transfer and mass transfer processes. Its core working principle is to absorb the heat of the high-temperature gaseous refrigerant inside the coil by partially evaporating the water sprayed outside the coil, so that the refrigerant changes from a gaseous state to a liquid state.

[0003] However, during the operation of existing evaporative condensers, when air from the external environment flows into the internal cooling water, dust in the air often adheres to the cooling water. As it accumulates, the impurities in the cooling water increase, which often leads to clogging of the spray components. At the same time, the impurities adhering to the surface of the heat exchange coils also seriously affect the efficiency of heat exchange operations, thus adversely affecting the use by personnel. Utility Model Content

[0004] The purpose of this invention is to provide a compact multi-stage evaporative condenser that can filter dust from the air during operation, preventing the circulating water from becoming dirty due to dust adhering to it, while ensuring that the heat exchange operation can be carried out stably for a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compact multi-stage evaporative condenser, comprising a shell, axial flow fans fixedly installed at both ends of the top of the shell, a circulation pump fixedly installed at the lower end of the left side of the shell, a water spray pipe fixedly installed between the output end of the circulation pump and the upper end of the left side of the shell cavity via a pipe, a multi-stage heat exchange coil fixedly installed on the right side of the shell cavity, air guide holes opened at both ends of both sides of the shell, an air guide frame plate contacting the surface of the air guide hole with the outer surface of the shell, an air inlet grille fixedly connected to the middle end of the air guide frame plate, a mounting frame plate slidably connected to the inner cavity of the air guide frame plate, the surface of the mounting frame plate contacting the surface of the air guide hole, and a dust filter fixedly installed at the middle end of the mounting frame plate.

[0006] As a preferred embodiment, the two ends of both sides of the outer surface of the housing are fixedly connected to a limiting frame, the upper end of the air guide frame plate contacts the surface of the limiting frame, both ends of the limiting frame are provided with cotter pin grooves, and both ends of the top of the air guide frame plate are provided with receiving holes.

[0008] As a preferred embodiment, limit bars are fixedly connected to both ends of the inner cavity of the air guide frame plate, and the surface of the mounting frame plate is slidably connected to the surface of the limit bars.

[0009] As a preferred embodiment, the lower end of the air guide frame is movably connected to a supporting shaft via a bearing, and the two sides of the supporting shaft are fixedly connected to the lower end of the outer surface of the housing.

[0010] As a preferred embodiment, a support base is fixedly connected to all four sides of the bottom of the outer surface of the shell, a support base plate is fixedly connected between the bottoms of the two support bases, a water guide pipe is fixedly connected to the lower left side of the shell, there are two water guide pipes, a sealing cap is threaded to the left side of the water guide pipe, and a flow guide plate is fixedly connected to the right side of the bottom of the inner cavity of the shell.

[0011] As a preferred embodiment, a metal protective mesh cover is fixedly installed on the top of the axial flow fan.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the design of the housing, enables a compact combination of the axial flow fan, circulating pump, water spray pipe, and multi-stage heat exchange coil, effectively reducing the space occupied during overall operation. The arrangement of the circulating pump, water spray pipe, multi-stage heat exchange coil, axial flow fan, air inlet grille, air guide frame, and air guide holes allows for rapid heat exchange of the gaseous refrigerant flowing inside the multi-stage heat exchange coil, enabling condensation of the gaseous refrigerant. Simultaneously, the installation of the frame and dust filter effectively filters dust from the air carried by the axial flow fan during operation, preventing large amounts of dust from entering the housing and adhering to the surface of the multi-stage heat exchange coil, forming impurities in the cooling water, and clogging the water spray pipe. This ensures long-term stable operation of the entire system.

[0014] 2. This utility model, through the setting of a limiting frame, cotter pin groove, receiving hole, support spring, and pin block, can limit and fix the upper end of the air guide frame plate, preventing the air guide frame plate from detaching from one side of the housing. When personnel need to disassemble, clean, or replace the dust filter later, pushing the pin block downwards can compress the support spring until the pin block can disengage from the surface of the cotter pin groove, thus releasing the limit on the top of the air guide frame plate. Then, personnel can pull the air guide frame plate to rotate, which can drive the mounting frame plate and dust filter to rotate until the surface of the mounting frame plate can disengage from the surface of the air guide hole. Personnel can then slide the mounting frame plate and dust filter off from one side of the air guide frame plate, greatly facilitating the maintenance and cleaning of the dust filter and making it easy for personnel to use. The setting of the grip rod makes it easy for personnel to press and push the pin block.

[0015] 3. This utility model effectively limits the movement between the mounting frame and the air guide frame by setting a limiting stop, preventing the mounting frame from tilting or shifting inside the air guide frame. The supporting shaft supports the air guide frame and the housing. The supporting base and supporting bottom plate support the bottom of the housing. The water pipe and sealing cover facilitate the addition and replacement of cooling water inside the housing. The guide plate guides the cooling water inside the housing. The metal protective mesh cover protects the top of the axial flow fan. Attached Figure Description

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, this utility model provides a compact multi-stage evaporative condenser, including a shell 1. Axial flow fans 10 are fixedly installed at both ends of the top of the shell 1. A circulation pump 2 is fixedly installed at the lower left end of the shell 1. A water spray pipe 11 is fixedly installed between the output end of the circulation pump 2 and the upper left end of the inner cavity of the shell 1 through a pipe. A multi-stage heat exchange coil 12 is fixedly installed on the right side of the inner cavity of the shell 1. Air guide holes 15 are opened at both ends of both sides of the shell 1. An air guide frame plate 5 is in contact with the surface of the air guide hole 15 and the outer surface of the shell 1. An air inlet grille 6 is fixedly connected to the middle end of the air guide frame plate 5. A mounting frame plate 13 is slidably connected to the inner cavity of the air guide frame plate 5. The surface of the mounting frame plate 13 is in contact with the surface of the air guide hole 15. A dust filter screen 14 is fixedly installed at the middle end of the mounting frame plate 13.

[0025] In this technical solution, the housing 1 allows for a compact combination of the axial flow fan 10, circulating pump 2, water spray pipe 11, and multi-stage heat exchange coil 12, effectively reducing the space occupied during operation. The arrangement of the circulating pump 2, water spray pipe 11, multi-stage heat exchange coil 12, axial flow fan 10, air inlet grille 6, air guide frame 5, and air guide holes 15 enables rapid heat exchange of the gaseous refrigerant flowing through the multi-stage heat exchange coil, allowing for condensation. Furthermore, the installation of the frame 13 and dust filter 14 effectively filters dust from the air driven by the axial flow fan 10 during operation, preventing large amounts of dust from entering the housing 1 and adhering to the surface of the multi-stage heat exchange coil 12, forming impurities in the cooling water, and clogging the water spray pipe 11. This ensures long-term stable operation of the entire system.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 4 As shown, the outer surface of the housing 1 is fixedly connected to both ends of the limiting frame 8. The upper end of the air guide plate 5 contacts the surface of the limiting frame 8. Both ends of the limiting frame 8 are provided with cotter pin grooves 21. Both ends of the top of the air guide plate 5 are provided with receiving holes 17. A pin block 19 is slidably connected between the surface of the receiving hole 17 and the surface of the cotter pin groove 21. A support spring 18 is fixedly connected between the bottom of the pin block 19 and the bottom of the receiving hole 17. A gripping rod 20 is fixedly connected to the top of the pin block 19. The gripping rod 20 is U-shaped.

[0028] In this technical solution, the upper end of the air guide frame 5 can be limited and fixed by the setting of the limiting frame 8, the cotter pin groove 21, the receiving hole 17, the support spring 18, and the pin block 19, preventing the air guide frame 5 from detaching from one side of the housing 1. Furthermore, when personnel need to disassemble, clean, or replace the dust filter 14 later, pushing the pin block 19 downwards compresses the support spring 18 until the pin block 19 disengages from the surface of the cotter pin groove 21, thus securing the top of the air guide frame 5. Once the limit is released, personnel can pull the air guide frame 5 to rotate, which in turn rotates the mounting frame 13 and the dust filter 14. After the surface of the mounting frame 13 is separated from the surface of the air guide hole 15, personnel can slide the mounting frame 13 and the dust filter 14 off one side of the air guide frame 5. This greatly facilitates the maintenance and cleaning of the dust filter 14 and makes it easier for personnel to use. The grip rod 20 makes it easy for personnel to press and push the pin block 19.

[0029] Example 3:

[0030] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the air guide frame plate 5 has two ends of both sides of the inner cavity fixedly connected to limit baffles 16. The surface of the mounting frame plate 13 is slidably connected to the surface of the limit baffles 16. The lower end of the air guide frame plate 5 is movably connected to a support shaft 7 through a bearing. The two sides of the support shaft 7 are fixedly connected to the lower end of the outer surface of the housing 1. Support bases 4 are fixedly connected to the bottom of the outer surface of the housing 1. A support base plate is fixedly connected between the bottoms of the two support bases 4. A water guide pipe 3 is fixedly connected to the lower left side of the housing 1. There are two water guide pipes 3. A sealing cap is threaded to the left side of the water guide pipe 3. A flow guide plate 22 is fixedly connected to the right end of the bottom of the inner cavity of the housing 1. A metal protective mesh cover 9 is fixedly installed on the top of the axial flow fan 10.

[0031] In this technical solution, the limiting baffle 16 effectively limits the movement between the mounting frame 13 and the air guide frame 5, preventing the mounting frame 13 from tilting or shifting inside the air guide frame 5. The supporting shaft 7 provides support between the air guide frame 5 and the housing 1. The supporting base 4 and the supporting bottom plate provide support for the bottom of the housing 1. The water pipe 3 and the sealing cover facilitate the addition and replacement of cooling water inside the housing 1. The guide plate 22 guides the cooling water inside the housing 1. The metal protective mesh cover 9 protects the top of the axial flow fan 10.

[0032] The working principle of this utility model is as follows: The housing 1 allows for a compact combination of the axial flow fan 10, circulating pump 2, water spray pipe 11, and multi-stage heat exchange coil 12, effectively reducing the space occupied during operation. When condensation of the gaseous refrigerant flowing inside the multi-stage heat exchange coil 12 is required, the circulating pump 2 drives the cooling water inside the housing 1 to spray onto the surface of the multi-stage heat exchange coil 12 through the water spray pipe 11. This allows for rapid heat exchange between the sprayed water and the gaseous refrigerant inside the multi-stage heat exchange coil 12, and some of the water evaporates, carrying away a large amount of heat, thus allowing the gaseous refrigerant to condense. Rapid condensation is achieved, and under the action of the axial flow fan 10, it can drive the outside air through the air intake grille 6, air guide frame plate 5 and air guide hole 15 into the interior of the housing 1. At the same time, it can carry away a large amount of water vapor inside the housing 1, further improving the heat dissipation effect. Meanwhile, by installing the frame plate 13 and dust filter 14, the dust in the air driven by the axial flow fan 10 can be effectively filtered during the overall operation, preventing a large amount of dust from entering the interior of the housing 1 and adhering to the surface of the multi-stage heat exchange coil 12 and forming a large amount of impurities in the cooling water, which would cause the water spray pipe 11 to be blocked. This ensures that the overall operation can be stable for a long time.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
