Description

Technical Field

[0001] The utility model relates to the field of air-cooled box-type chillers, and particularly to an air-cooled box-type chiller. Background Technique

[0002] An air-cooled box-type chiller, also known as an air-cooled chiller, is a device that uses air-cooling technology for heat dissipation and achieves a refrigeration effect by means of a compressor refrigerant. The core of its operation lies in a series of thermodynamic cycle processes such as compression, condensation, throttling, and evaporation to continuously produce chilled water.

[0003] However, in practical applications, this type of chiller faces some challenges, mainly due to the separate installation of the circuit board and its control structure and the air-cooled fan inside the box. This layout first leads to an increase in the floor area of the device. Since the circuit board and the control structure require independent installation spaces, and in order to maintain electrical safety and air circulation, a certain distance needs to be maintained between them and the fan system, which undoubtedly increases the overall volume of the device, posing a great challenge for a space-compact installation environment.

[0004] In addition, from the perspective of heat dissipation efficiency, this separate layout also has deficiencies. The circuit board and the control structure generate heat during operation. If this heat cannot be dissipated quickly and effectively, it may lead to an increase in the temperature of the components, which in turn has a negative impact on their working stability and service life. The main function of the air-cooled fan is to reduce the overall temperature inside the box through forced convection. However, due to its relatively long distance from the circuit board and the control structure, it may not be able to directly dissipate heat effectively from these main heat sources, resulting in local heat accumulation and reducing the overall heat dissipation efficiency. Content of the Utility Model

[0005] The main purpose of the utility model is to provide an air-cooled box-type chiller, which can effectively solve the problems raised in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An air-cooled box-type chiller, including a cooling grille device, an air-cooled fan, and a liquid joint. The cooling grille device is located above the air-cooled fan, and the liquid joint is located at the lower part of the side wall of the air-cooled fan. The liquid joint is connected to the cooling grille device through an infusion pipeline;

[0008] A connection box is provided at the connection between the cooling grille device and the air-cooled fan, and the cooling grille device is installed inside the connection box. A box top cover is installed on the upper end of the connection box. An L-shaped connection frame is provided on the side wall of the air-cooled fan, and a heat conduction plate is installed on the L-shaped connection frame. Heat conduction columns on the side wall of the heat conduction plate pass through the connection box and extend into the cooling grille device to achieve heat transfer;

[0009] A connection side box is installed at the side end of the heat conduction plate, and a docking head is provided on the side wall of the connection side box. A plurality of fixing frames are arranged in the connection side box, and a circuit printed board and a controller are installed on the fixing frames. The circuit printed board and the controller are connected to the air-cooled fan through wires, and the heat in the connection side box is transferred to the cooling grille device through the heat conduction plate.

[0010] Among them, the connection box is fixed on the top cover of the box body by bolts, and the connection box and the cooling grille device are fixed by bolts; the air-cooled fan and the connection box are fixed by bolts;

[0011] Among them, the air-cooled fan is divided into a driving motor and a rotating fan. The rotating fan is installed on the output end of the driving motor. The L-shaped connecting frame is welded on the driving motor of the air-cooled fan, and a round hole is opened on the end face of the L-shaped connecting frame;

[0012] Among them, heat conduction ribs are provided on the surface of the heat conduction plate. The surface of the heat conduction ribs is coated with heat conduction silicone grease and is in contact with the connection side box. The openings on the end faces of the connection side box, the heat conduction plate and the L-shaped connecting frame are aligned. Bolts, nuts and anti-slip washers are inserted to realize the connection of the three;

[0013] Among them, the cross section of the fixing frame is designed in a "U" shape, and a waist-shaped hole is opened on the end face of the fixing frame. The circuit printed board and the controller are connected to the fixing frame by bolts;

[0014] Among them, the connection side box, the heat conduction plate, the air-cooled fan and the cooling grille device are installed and distributed in a compact manner, in order to reduce the space occupied by the air-cooled box-type water chiller.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, the heat conduction plate is directly connected to the inside of the cooling grille device through the heat conduction columns on its side wall, realizing the rapid conduction of heat. This design greatly improves the heat transfer efficiency from the connection side box (including the circuit printed board and the controller) to the cooling grille, thereby enhancing the heat dissipation performance of the system. The heat conduction plate not only has the function of heat transfer, but also enhances the stability of the entire air-cooled system through its installation structure. As a bridge between the connection side box and the cooling grille, it effectively reduces the stress concentration caused by heat conduction and improves the overall stability of the system.

[0017] The design of the heat conduction plate enables the core components such as the connection side box, heat conduction plate, air-cooled fan, and cooling grille to be tightly installed together, reducing the occupied space of the equipment. This compact installation distribution method not only improves the space utilization rate but also enhances the aesthetics of the equipment. The heat conduction plate and its related components adopt a modular design, which is convenient for subsequent maintenance and replacement. When a certain component needs to be repaired or replaced, it can be easily disassembled and reinstalled, reducing the maintenance cost and time.

[0018] Through the carefully designed installation layout, each component is tightly installed together, avoiding waste of space. This efficient space utilization method enables the equipment to occupy less space while maintaining high performance, making it convenient to install and deploy in a limited space.

[0019] In the compact installation layout, the requirements for heat dissipation and ventilation are particularly considered. Key components such as the air-cooled fan and cooling grille are placed in positions where heat dissipation and ventilation are easy, ensuring that the system can maintain good heat dissipation performance even under high-load operation.

[0025] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Such as Figure 1 - Figure 4As shown in the figure, an air-cooled box chiller, whose core components include a cooling grille device 3, a high-efficiency air-cooled fan 4, and a liquid connector 5. The cooling grille device 3 is ingeniously arranged on the top of the air-cooled fan 4 to ensure the maximization of the cooling effect, while the liquid connector 5 is cleverly placed at the lower part of the side wall of the air-cooled fan 4, facilitating the access and export of liquid. Between the liquid connector 5 and the cooling grille device 3, they are tightly connected through a precisely designed infusion pipeline 6 to achieve the smooth circulation of the coolant.

[0027] At the connection between the cooling grille device 3 and the air-cooled fan 4, a connection box 2 is specially added. This connection box 2 not only stably supports the cooling grille device 3 but also provides good protection for it. On the top of the connection box 2, a box top cover 1 is cleverly installed to further enhance the sealing and stability of the overall structure.

[0028] To improve the heat transfer efficiency, the side wall of the air-cooled fan 4 is specially designed with an L-shaped connecting frame 7, and an efficient heat conducting plate 8 is installed on this connecting frame. Heat conducting columns are provided on the side wall of the heat conducting plate 8, and these heat conducting columns cleverly pass through the connection box 2 and reach the inside of the cooling grille device 3, achieving efficient heat transfer and dissipation.

[0029] In addition, a connection side box 9 is installed at the side end of the heat conducting plate 8. This side box not only provides installation space for the circuit printed board 11 and the controller 13 but also connects with other devices or systems through the docking head 10 on its side wall. Multiple fixing frames 12 are provided inside the connection side box 9. These fixing frames 12 adopt a unique "U" - shaped design and are provided with waist holes, facilitating the stable installation of the circuit printed board 11 and the controller 13. The circuit printed board 11 and the controller 13 are tightly connected to the air-cooled fan 4 through wires, and the heat inside the connection side box 9 is transferred to the cooling grille device 3 through the heat conducting plate 8, achieving efficient heat management and control.

[0030] In terms of connection and fixation, the air-cooled box chiller system adopts a bolt fixation method. The connection box 2 is stably fixed on the box top cover 1 through bolts, and between the cooling grille device 3 and the connection box 2, as well as between the air-cooled fan 4 and the connection box 2, they are also tightly connected through bolts. This connection method is not only simple and reliable but also convenient for subsequent maintenance and replacement.

[0031] The design of the air-cooled fan 4 is also unique. It is divided into a drive motor and a rotating fan. The rotating fan is installed on the output end of the drive motor to achieve efficient wind output. The L-shaped connecting frame 7 is firmly installed on the drive motor of the air-cooled fan 4 by welding, providing a solid foundation for the installation of the heat conducting plate 8. A round hole is opened on the end face of the L-shaped connecting frame 7 to facilitate the connection and fixation with other components.

[0032] To further improve the heat conduction efficiency, heat conduction ribs are specially designed on the surface of the heat conduction plate 8, and heat conductive silicone grease is coated on its surface. These designs enable the heat conduction plate 8 to more effectively contact the connecting side box 9 and transfer heat. At the same time, the end face openings of the connecting side box 9, the heat conduction plate 8, and the L-shaped connecting frame 7 are aligned, and bolts, nuts, and anti-slip washers are inserted to achieve tight connection and fixation among the three.

[0033] The entire air-cooled chiller system adopts a compact installation distribution method. Core components such as the connecting side box 9, the heat conduction plate 8, the air-cooled fan 4, and the cooling grille device 3 are cleverly arranged together to minimize the occupied space of the equipment and improve the overall aesthetics.

[0034] Installation process: Ensure that all components (cooling grille device 3, high-efficiency air-cooled fan 4, connecting box 2, box top cover 1, L-shaped connecting frame 7, heat conduction plate 8, connecting side box 9, fixing frame 12, circuit printed board 11, controller 13, etc.) are intact, and prepare the necessary installation tools and materials (bolts, nuts, anti-slip washers, etc.). Place the connecting box 2 at the predetermined position and initially fix it on the installation foundation using bolts. Place the cooling grille device 3 on top of the connecting box 2 and tightly connect the two with bolts to ensure stability. Align the bottom of the high-efficiency air-cooled fan 4 with the lower part of the connecting box 2 and fix it with bolts. Ensure that the drive motor and the rotating fan part of the fan are installed correctly and firmly.

[0035] Weld the L-shaped connecting frame 7 to the drive motor of the air-cooled fan 4, then install the heat conduction plate 8 on the L-shaped connecting frame 7 and fix it with bolts. The heat conduction columns of the heat conduction plate 8 should pass through the connecting box 2 and reach inside the cooling grille device 3. Place the connecting side box 9 on the side of the air-cooled fan 4 and connect and fix it with the L-shaped connecting frame 7 and the connecting box 2 using bolts. Ensure that the side wall docking head 10 of the connecting side box 9 is aligned with the connection port of other equipment or systems. Inside the connecting side box 9, firmly install the circuit printed board 11 and the controller 13 using the fixing frame 12. Ensure that the wire connections between them are correct. Finally, place the box top cover 1 on top of the connecting box 2 and tightly fix it to the connecting box 2 with bolts to enhance the sealing and stability of the overall structure.

[0036] During use: Before starting the air-cooled box chiller, check whether all components are firmly installed, whether the electrofusion connection is correct, and whether there are any leaks or abnormalities. Start the entire system through the controller 13. The controller 13 will monitor and control the working status of each component to ensure the normal operation of the system. After startup, the coolant enters the infusion pipeline 6 through the liquid joint 5 and flows through the cooling grille device 3 for heat exchange. The coolant after heat exchange flows back to the liquid source through the infusion pipeline 6 again to form a cycle. The high-efficiency air-cooled fan 4 starts to work, generating a strong wind through the rotating fan blades, blowing over the cooling grille device 3 to accelerate the dissipation of heat. The heat conducting plate 8 transfers the heat in the connecting side box 9 to the cooling grille device 3 through the heat conducting columns for heat exchange with the coolant. At the same time, the design of the L-shaped connecting frame 7 and the heat conducting ribs improves the heat transfer efficiency. During the operation of the system, monitor various parameters (such as temperature, pressure, flow rate, etc.) through the display screen of the controller 13 and make adjustments and maintenance as needed. Regularly check the connection conditions and performance of each component to ensure the long-term stable operation of the system. When it is necessary to stop the air-cooled box chiller, perform the shutdown operation through the controller 13. Turn off the power of all components and wait for the system to completely stop running before performing other operations or maintenance.
