Description

Technical Field

[0001] This utility model belongs to the technical field of evaporative condensers, specifically relating to an antifreeze water distributor for evaporative condensers. Background Technology

[0002] The water distributor of an evaporative condenser is one of the core components of the evaporative condenser. Its function is to spray water evenly onto the surface of the heat exchange components, and achieve heat exchange through the evaporation of water, thus ensuring the stable operation of the heat exchange cycle of the evaporative condenser.

[0003] The basic structure of existing evaporative condenser water distributors typically only includes water distribution pipes, a simple support structure, and water distribution components, which has several shortcomings: First, it lacks efficient heat conduction and antifreeze structures, and the water distribution pipes are prone to freezing due to insufficient heat in low-temperature environments, leading to failure of the water distribution function; Second, the heat exchange structure design is simple, with limited heat exchange area and low heat exchange efficiency; Third, it has insufficient ability to remove dust and other impurities from the airflow, which can easily cause impurities to accumulate and affect the operation of the device; Fourth, the structural stability is poor, and the installation of some components lacks reasonable spatial layout. At the same time, the heat conduction components are mostly made of materials with poor thermal conductivity, which cannot quickly and evenly transfer heat to the water distribution pipes and surrounding structures, making it difficult to meet the reliable operation requirements of evaporative condensers under complex operating conditions, especially in low-temperature environments. Utility Model Content

[0004] In view of the problems of easy freezing at low temperatures, low heat exchange efficiency, poor dust removal effect, insufficient structural stability and inconvenient installation of water distributors for evaporative condensers in the existing technology, this utility model provides an antifreeze water distributor for evaporative condensers.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an antifreeze water distributor for an evaporative condenser, comprising an outer shell, characterized in that the inner part of the outer shell is provided with heat exchange tubes, vent pipes, water distribution pipes, a support frame, and a heat-conducting plate; the bottom of the outer shell is provided with an air inlet grille, and several evenly distributed vent pipes are provided above the air inlet grille; the heat exchange tubes are placed between the vent pipes in a vertical and spaced manner; the upper part of the vent pipes is fixedly connected to the support frame through heat exchange plates, the support frame is sleeved on the outside of the water distribution pipes, and the support frame includes several evenly distributed support rods distributed on both sides of the water distribution pipes, with an outer frame fixedly connected to both ends of the support rods and the heat exchange plates by bolts.

[0006] Preferably, the number of vent pipes is adapted to the arrangement of heat exchange pipes, and the height of the vent pipes is not lower than the height of the heat exchange pipes, with the heat exchange pipes closely attached to the vent pipes.

[0007] Preferably, the vent pipe is fixed inside the outer casing and communicates with the air intake grille. The vent pipe located at the edge is L-shaped, with installation space left on the inner side of its bend.

[0008] Preferably, the installation space is equipped with a water pump connected to the water distribution pipe, and an installation plate is fixedly connected to the other side of the water pump. The installation plate and the outer shell are positioned by a fixing plate.

[0009] Preferably, the support rod, outer frame, heat exchange fins, and vent pipe are all metal tubes with high thermal conductivity.

[0010] One or more technical solutions provided in this application embodiment have at least the following technical effects or advantages compared with the prior art:

[0011] This invention achieves efficient heat transfer through the close cooperation of the heat exchange tube and the vent tube, and the application of high thermal conductivity materials, effectively solving the problem of freezing of the water distribution pipe in low-temperature environments. The spaced insertion structure of the vent tube and the heat exchange tube significantly increases the heat exchange area. Combined with the contact between water and both during water distribution, it greatly improves heat exchange efficiency and has a good dust removal effect. The support frame consists of a support rod and an outer frame, which is connected to the vent tube through heat exchange plates, ensuring the structural stability of the water distribution pipe and enhancing the uniform transfer of heat.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figures 1 to 4 As shown, an antifreeze water distributor for an evaporative condenser includes an outer shell 1, which serves as the overall structural carrier. An air inlet grille 11 is provided at the bottom of the outer shell 1. The air inlet grille 11 is a grille structure with several longitudinal ventilation slots, which is used to introduce airflow and cooperate with the ventilation pipe 3 to achieve heat transfer under hot gas pressure.

[0023] Inside the outer casing 1, several evenly distributed vent pipes 3 are arranged above the air intake grille 11. The vent pipes 3 are hollow columnar structures, fixed inside the outer casing 1 and connected to the air intake grille 11. Heat exchange pipes 2 are vertically spaced between the vent pipes 3, and the heat exchange pipes 2 are close to the vent pipes 3. The number of vent pipes 3 is adapted to the arrangement of the heat exchange pipes 2, and the height of the vent pipes 3 is not lower than the height of the heat exchange pipes 2. This layout allows the heat exchange pipes 2 to efficiently heat the vent pipes 3, laying the foundation for subsequent heat conduction. Among them, the vent pipes 3 located at the edge are L-shaped, and an installation space 32 is left on the inner side of the bend. A water pump 7 connected to the water distribution pipe 4 is installed in the installation space 32. A mounting plate 71 is fixed to the other side of the water pump 7. The mounting plate 71 is positioned to the outer casing through a fixing plate. This design provides reasonable installation space for components such as the water pump 7, facilitating assembly and maintenance.

[0024] The vent pipe 3 is fixedly connected to the support frame 5 via heat exchange fins 31, and the support frame 5 is fitted over the water distribution pipe 4. The support frame 5 includes several evenly distributed support rods 51 on both sides of the water distribution pipe 4, and the two ends of the support rods 51 are fixedly connected to an outer frame 52 that is fixedly connected to the heat exchange fins 31 by bolts. The water distribution pipe 4 is a horizontally arranged tubular structure with water distribution holes on its wall for evenly distributing water.

[0025] In addition, the support rod 51, outer frame 52, heat exchange plate 31 and vent pipe 3 are all metal tubes with high thermal conductivity (such as copper, aluminum, etc.), which ensures that heat can be quickly and evenly transferred from vent pipe 3 to support frame 5 through heat exchange plate 31, thereby making water distribution pipe 4 heated evenly and effectively avoiding low temperature freezing.

[0026] During operation, heat exchange tube 2 heats vent pipe 3, and vent pipe 3 transfers heat to support frame 5 through heat exchange fins 31. Support frame 5 then transfers heat to water distribution pipe 4. Air intake grille 11 at the bottom of outer shell 1 introduces airflow. Under the action of hot air pressure, heat is transferred upward with the airflow, further ensuring the antifreeze effect of water distribution pipe 4. Water sprayed from water distribution pipe 4 contacts heat exchange tube 2 and vent pipe 3, which enhances the heat exchange effect on the one hand, and removes dust and other impurities from the airflow on the other hand. Water pump 7 in the edge installation space 32 provides power for water distribution, ensuring that the water distribution process is stable.

[0027] This utility model, as the core water distribution component of an evaporative condenser, needs to be used in conjunction with conventional components of existing evaporative condensers such as fans, water tanks, compressors, and refrigerant pipelines. Its usage and structural states under different operating conditions (such as low-temperature environments, normal-temperature environments, and dusty industrial environments) are as follows:

[0028] I. Usage and structural condition in low-temperature environments (such as outdoor use in winter and cold regions)

[0029] In low-temperature environments, the water distributor of existing evaporative condensers is prone to water distribution interruption due to the freezing of water in the distribution pipes. This device solves this problem by linking with the existing system through an anti-freeze structure:

[0030] Outer shell 1: It is fixed to the heat exchange chamber of the existing evaporative condenser by bolts, and its inner wall is in contact with the insulation layer of the existing condenser to reduce internal heat loss; the bottom air inlet grille 11 is aligned with the air inlet channel at the bottom of the existing condenser to ensure that the external airflow enters the device through the grille.

[0031] Heat exchange tube 2: Both ends are connected to the high-temperature refrigerant outlet pipe of the existing compressor and the refrigerant return pipe of the condenser through flanges. The refrigerant condenses and releases heat in the heat exchange tube (the conventional heat exchange logic of the existing technology). Because the heat exchange tube 2 is close to the vent pipe 3, the heat is quickly transferred to the vent pipe 3, causing the temperature of the vent pipe 3 to rise.

[0032] Vent pipe 3: The hollow structure is connected to the air intake grille 11. After the fan at the bottom of the existing condenser is started, the airflow enters the vent pipe 3 through the air intake grille 11 and is heated by the vent pipe 3 to form a hot airflow. Since the height of the vent pipe 3 is not lower than that of the heat exchange tube 2, the hot airflow can cover the entire section of the heat exchange tube 2, avoiding the heat exchange tube 2 from frosting at low temperature.

[0033] Support frame 5 and water distribution pipe 4: The water inlet end of the water distribution pipe 4 is connected to the water supply line of the existing water tank through a hose. The outer frame 52 of the support frame 5 is fixed to the crossbeam at the top of the existing condenser with bolts to ensure that the water distribution pipe 4 is suspended horizontally. The heat of the vent pipe 3 is transferred to the outer frame 52 through the heat exchange plate 31, and then evenly conducted to the outer wall of the water distribution pipe 4 through the support rod 51, so that the water temperature in the water distribution pipe 4 is maintained above the freezing point to avoid freezing.

[0034] Edge L-shaped vent pipe 3 and water pump 7: The water pump 7 in the installation space 32 is connected in series in the existing water tank and water distribution pipe 4. The water pump 7 is connected to the outer shell 1 and the existing condenser mounting bracket through the mounting plate 71. The water pump 7 runs continuously at low temperatures (linked with the existing control system) and works with the heating of the water distribution pipe 4 to ensure smooth water circulation.

[0035] II. Usage and structural condition in normal temperature environments

[0036] At room temperature, the device focuses on improving heat exchange efficiency and enhances heat exchange in conjunction with existing systems:

[0037] Heat exchange tube 2 and vent pipe 3: Heat exchange tube 2 still heats vent pipe 3 by releasing heat from the refrigerant, but because the ambient temperature is high, the heat of vent pipe 3 is transferred more through contact with the water distribution pipe; the water sprayed from the water distribution holes of water distribution pipe 4 falls evenly on the surface of heat exchange tube 2 and vent pipe 3 (the basic function of the existing water distributor). Because the two are inserted alternately, the water film coverage area is increased by more than 30% compared with the existing single heat exchange tube structure, the evaporation rate is improved, and the heat exchange effect of the existing condenser is enhanced.

[0038] Air intake grille 11 and airflow: The airflow driven by the existing fan enters the ventilation pipe 3 through the air intake grille 11. When the airflow flows in the ventilation pipe 3, it carries heat upward (the auxiliary water distribution pipe 4 is kept warm, and no additional energy is required). Furthermore, because the airflow comes into contact with the wet surface of the ventilation pipe 3 and the heat exchange pipe 2, the water evaporation is accelerated, further improving the heat exchange efficiency.

[0039] Support frame 5: At this time, it mainly provides structural support for the water distribution pipe 4. The rigid structure of the support rod 51 and the outer frame 52 prevents the water distribution pipe 4 from shaking due to water flow impact, ensuring the uniformity of water distribution (existing water distributors often cause water distribution deviation due to unstable support).

[0040] III. Usage and structural conditions in dusty industrial environments (such as cement plants and machinery factories)

[0041] In dusty environments, existing water distributors are prone to reduced heat exchange efficiency due to dust adhering to heat exchange components. This device addresses this issue by integrating existing dust removal logic into its structural design.

[0042] The ventilation pipe 3 is linked with the water distribution system: the water sprayed from the water distribution pipe 4 forms a continuous water film on the surface of the heat exchange pipe 2 and the ventilation pipe 3. Dust (such as dust and metal shavings) brought in by the airflow through the air intake grille 11 is adsorbed after contact with the water film and flows down along the surface of the ventilation pipe 3 and the heat exchange pipe 2 with the water flow, and finally flows into the water tank at the bottom of the existing condenser (the water tank is equipped with a filter screen, which is the existing structure). This realizes the linkage of "water distribution-dust removal-water circulation" and reduces the frequency of manual cleaning of the existing system.

[0043] Heat exchanger 31 and support frame 5: The heat exchanger 31 and support frame 5 are made of high thermal conductivity metal and have smooth surfaces. The dust attached to them is easily washed away by airflow or dripping water droplets, avoiding the problem of reduced heat conduction efficiency caused by dust accumulation in the existing water distributor support structure.

[0044] Air intake grille 11: Its longitudinal ventilation slots can pre-filter large particulate impurities (such as debris), reduce the amount of dust entering the ventilation pipe 3, and form a double protection with the subsequent water film dust removal, protecting the core heat exchange components of the existing condenser.

[0045] In summary, this device, through precise linkage with the refrigerant circuit, water circulation system, and air circulation system of the existing evaporative condenser, can not only exert its core advantages such as antifreeze, efficient heat exchange, and dust removal under different operating conditions, but also adapt to the installation and operation logic of existing equipment, thus solving the problem of insufficient adaptability of existing water distributors under special operating conditions.

[0046] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
