Description

Technical Field

[0001] This invention relates to the field of mortar setting test technology, and in particular to an air-cooled water cooling device. Background Technology

[0002] Air-cooled industrial chillers, also known as air-cooled box-type industrial chillers, are industrial refrigeration equipment that uses air as a heat exchange source and is equipped with a dedicated fan. They achieve cooling through a refrigeration cycle system and are mainly used in industries such as medical, biological, chemical, laser, metallurgy, equipment manufacturing, electroplating, and plastics processing. This equipment uses air circulation heat dissipation technology and does not require an external water source or cooling tower. It is suitable for areas with water shortages or poor water quality. The selection of this type of chiller requires comprehensive consideration of the company's scale, water source conditions, and environmental protection requirements. Air-cooled chillers are one type of chiller that cools room temperature water to a certain temperature through the chiller's compressor to enhance the cooling of molds or machines. When used as a standalone unit, the heat dissipation device is an internal fan. It mainly consists of three interconnected systems: a refrigerant circulation system, a water circulation system, and an electrical automatic control system.

[0003] A search revealed Chinese Patent Publication No. CN213119580U, which discloses an air-cooled chiller for automated equipment. The chiller includes an outer frame, with an air-cooled fan mounted on the top surface of the frame. A condenser is mounted on one side of the bottom surface inside the outer frame. The condenser includes a shell, which consists of an outer layer, an inner layer, and a refrigerant interlayer between the outer and inner layers. An intermediate cylinder is located in the middle of the inner layer. A hollow rotating shaft is inserted into the upper part of the shell. Shaft brackets are fixed to both sides of the lower end of the hollow rotating shaft. A scraper is mounted below the shaft brackets. A space is provided between the scraper and the inner layer. This invention features a narrow refrigerant cavity for cooling equipment. The condenser contains an inner refrigerant cavity and a refrigerant jacket. A scraper clears the refrigerant from the narrow cavity, allowing the refrigerant within to cool the heat-carrying refrigerant. The narrow cavity's narrow width results in good cooling. However, both the cooling fan and the top of the chiller are secured with screws, requiring the user to be above the chiller to see the screws and use tools to remove them – a very inconvenient process. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an air-cooled chiller, which aims to improve the problem that in the prior art, the top of the cooling fan and the chiller are fixed with screws, so when disassembling, one needs to be above the chiller to see the fixing position of the screws, and then remove them with the help of tools, which is very inconvenient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air-cooled chiller includes a fixed frame, a chiller is fixedly connected to the upper part of the inner wall of the fixed frame, a connecting block is installed on the top of the chiller, and a fixing mechanism is installed at each of the four corners of the top wall of the fixed frame. The fixing mechanism is used to fix components. Multiple cooling fans are equidistantly installed on the top wall of the connecting block, and an installation mechanism is installed on the outer wall of the cooling fans. The installation mechanism is used to facilitate the disassembly of components. The fixing mechanism includes a housing, which is fixedly connected to the four corners of the top wall of the chiller. Multiple bases are equidistantly fixedly connected to the outer wall of the connecting block, and a drive assembly is installed on the inner wall of the housing.

[0006] The above technical solution, which connects the cooling fan to the chiller via a connecting block, allows the connecting block to be removed from the chiller before the cooling fan can be disassembled and installed. This reduces the need for operators to work in the air, making operation more convenient and facilitating equipment maintenance.

[0007] As a further description of the above technical solution: The drive assembly includes a bolt, which is rotatably connected to the upper part of the inner wall of the outer casing. A protrusion is threadedly connected to the lower part of the outer wall of the bolt. A fixing rod is slidably connected to the right side of the inner wall of the outer casing. The protrusion is slidably connected to the inner wall of the fixing rod. A limit block is fixedly connected to the end of the fixing rod.

[0008] The above technical solution involves placing the connecting block on the top wall of the chiller, then rotating bolt one. After bolt one rotates, it drives the protrusion on its outer wall, causing the protrusion to slide downwards inside the outer shell and compress the fixing rod. This causes the fixing rod to slide to the right inside the outer shell, thereby pushing the limiting block and causing the limiting block to slide into the inner wall of the base.

[0009] As a further description of the above technical solution: The limiting block is slidably connected to the outer wall of the base, and multiple limiting rods are slidably connected to both the limiting block and the inner wall of the base. A long plate is fixedly connected to the top of each limiting rod.

[0010] The above technical solution involves picking up the long plate, aligning the limiting rod at the bottom of the long plate with the insertion hole on the top wall of the limiting block, and then inserting it into the insertion hole. The limiting rod passes through the limiting block and the base, forming a stable connection.

[0011] As a further description of the above technical solution: The mounting mechanism includes a second outer shell, which is fixedly connected at equal intervals to the left and right sides of the outer wall of the cooling fan. Multiple mounting blocks are fixedly connected at equal intervals to the top wall of the connecting block, and multiple racks are slidably connected at equal intervals to the lower part of the inner wall of the second outer shell.

[0012] Through the above technical solution: rotating bolt two causes rack one to move up and down inside outer casing two. After rack one moves, it drives the gear to rotate.

[0013] As a further description of the above technical solution: A locking block is fixedly connected to the bottom of the rack two. Multiple mounting slots are equidistantly provided on the top wall of the mounting block. The locking block is slidably connected to the inner wall of the mounting slot. A transmission component is installed on the inner wall of the outer shell two.

[0014] Through the above technical solution: the gear rotates and then drives the rack two, so that the rack two drives the locking block to move synchronously to both sides and the middle inside the outer shell two, thereby allowing the locking block to open and close.

[0015] As a further description of the above technical solution: The transmission assembly includes a second bolt, which is threadedly connected to the upper part of the inner wall of the second outer casing. A rack is rotatably connected to the bottom end of the second bolt. Multiple gears are rotatably connected at equal intervals to the inner wall of the second outer casing. The rack is meshed with the gears, and the gears are meshed with the rack.

[0016] The above technical solution involves closing the locking block to insert it into the mounting slot, then opening the locking block so that its end is locked against the inner wall of the mounting slot, forming a stable connection. This facilitates the installation and disassembly of the cooling fan and improves maintenance efficiency.

[0017] As a further description of the above technical solution: A controller is installed on the outside of the fixing frame, and the controller is installed on the right side of the outer wall of the fixing frame.

[0018] The above technical solution allows the controller to receive signals from the device in real time via a cable and convert the signals into digital data.

[0019] As a further description of the above technical solution: The controller is equipped with a display screen on its top, which is fixedly connected to the right side of the top wall of the controller.

[0020] The above technical solution allows for the dynamic display of information on the screen, enabling real-time monitoring of evaporation temperature and condensation pressure parameters, and adjustment of the electronic expansion valve opening.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the connecting block is placed on the top wall of the chiller, and then the first bolt is rotated. After the first bolt is rotated, the protrusion on its outer wall is driven, causing the protrusion to slide downward inside the outer shell and compress the fixing rod. The fixing rod slides to the right inside the outer shell, thereby pushing the limiting block and causing the limiting block to slide into the inner wall of the base. Then, the long plate is picked up, and the limiting rod at the bottom of the long plate is perpendicular to the insertion hole on the top wall of the limiting block. Then, it is inserted into the insertion hole. The limiting rod passes through the limiting block and the base, forming a stable connection. The operation is convenient. By connecting the connecting block to the chiller, when cleaning and replacing the cooling fan, the connecting block can be removed from the chiller, and then the cooling fan can be disassembled and installed. This reduces the phenomenon of operators working in the air, making the operation more convenient and facilitating equipment maintenance.

[0022] 2. In this utility model, rotating bolt two causes rack one to move up and down inside outer shell two. After rack one moves, it drives gear to rotate. The rotating gear then drives rack two, causing rack two to drive the locking block to move synchronously to both sides and the middle inside outer shell two. This allows the locking block to open and close. When the locking block is closed, it is inserted into the mounting groove. When the locking block is opened, the end of the locking block is locked against the inner wall of the mounting groove, forming a stable connection. This facilitates the installation and disassembly of the cooling fan and improves maintenance efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an air-cooled chiller, comprising a fixed frame 1, a chiller 2 fixedly connected to the upper part of the inner wall of the fixed frame 1, a connecting block 5 installed on the top of the chiller 2, and a fixing mechanism 3 installed at each of the four corners of the top wall of the fixed frame 1 for fixing components. Multiple cooling fans 6 are equidistantly installed on the top wall of the connecting block 5, and an installation mechanism 4 is installed on the outer wall of the cooling fans 6 for easy disassembly of components. The fixing mechanism 3 includes a housing 305, which is fixedly connected to the four corners of the top wall of the chiller 2. Multiple bases 304 are equidistantly fixedly connected to the outer wall of the connecting block 5. A drive assembly 306 is installed on the inner wall of the housing. The drive assembly 306 includes a bolt 3063, which is rotatably connected to the upper part of the inner wall of the outer shell 305. A protrusion 3062 is threadedly connected to the lower part of the outer wall of the bolt 3063. A fixing rod 3061 is slidably connected to the right side of the inner wall of the outer shell 305. The protrusion 3062 is slidably connected to the inner wall of the fixing rod 3061. A limit block 303 is fixedly connected to the end of the fixing rod 3061. The limit block 303 is slidably connected to the outer wall of the base 304. Multiple limit rods 302 are slidably connected to both the limit block 303 and the inner wall of the base 304. A long plate 301 is fixedly connected to the top of the limit rod 302. Specifically, the connecting block 5 is placed on the top wall of the chiller 2, and then the bolt 3063 is rotated. After the bolt 3063 rotates, it drives the protrusion 3062 on its outer wall, causing the protrusion 3062 to slide downwards inside the outer shell 305 and compress the fixing rod 3061. This causes the fixing rod 3061 to slide to the right inside the outer shell 305, thereby pushing the limiting block 303. The limiting block 303 slides into the inner wall of the base 304. Then, the long plate 301 is lifted, causing the limiting block at the bottom of the long plate 301 to... The positioning rod 302 is perpendicular to the insertion hole on the top wall of the limiting block 303 and then inserted into the insertion hole. The limiting rod 302 passes through the limiting block 303 and the base 304 to form a stable connection, which is convenient to operate. By connecting it to the chiller 2 through the connecting block 5, when cleaning and replacing the cooling fan 6, the connecting block 5 can be removed from the chiller 2, and then the cooling fan 6 can be disassembled and installed. This reduces the phenomenon of operators working in the air, making the operation more convenient and facilitating equipment maintenance.

[0027] Reference Figure 1 , Figure 3 and Figure 5 The mounting mechanism 4 includes a second outer shell 402, which is fixedly connected at equal intervals to the left and right sides of the outer wall of the cooling fan 6. Multiple mounting blocks 406 are fixedly connected at equal intervals to the top wall of the connecting block 5. Multiple racks 403 are slidably connected at equal intervals to the lower middle part of the inner wall of the second outer shell 402. A locking block 404 is fixedly connected to the bottom of each rack 403. Multiple mounting slots 405 are slidably opened at equal intervals on the top wall of each mounting block 406, and the locking block 404 is slidably connected to the mounting slot 405. The inner wall of the outer shell 402 is equipped with a transmission assembly 401. The transmission assembly 401 includes a bolt 4011, which is threadedly connected to the upper part of the inner wall of the outer shell 402. The bottom end of the bolt 4011 is rotatably connected to a rack 4012. Multiple gears 4013 are equidistantly rotatably connected to the inner wall of the outer shell 402. The rack 4012 meshes with the gears 4013, and the gears 4013 mesh with the rack 403. Specifically, rotating bolt 4011 causes rack 4012 to move up and down within housing 402. After rack 4012 moves, it drives gear 4013, causing gear 4013 to rotate. Gear 4013 then drives rack 403, causing rack 403 to move synchronously to both sides and the center within housing 402. This allows the locking block 404 to open and close. When the locking block 404 closes, it inserts into the mounting slot 405. Then, the locking block 404 opens, locking its end against the inner wall of the mounting slot 405, forming a stable connection. This facilitates the installation and removal of the cooling fan 6, improving maintenance efficiency.

The controller 8 is a PLC programmable logic controller 8, Siemens S7-1200 series. The controller 8 is installed on the right side of the outer wall of the mounting bracket 1. A display screen 7 is installed on the top of the controller 8. The display screen 7 is fixedly connected to the right side of the top wall of the controller 8. Specifically, the controller 8 receives signals from the equipment in real time via cable, converts the signals into digital data, and dynamically displays the information on the display screen 7. It can monitor the evaporation temperature and condensation pressure parameters in real time and adjust the opening of the electronic expansion valve.

[0029] Working principle: Place connecting block 5 on the top wall of chiller 2, then rotate bolt 3063. The rotation of bolt 3063 drives the protrusion 3062 on its outer wall, causing protrusion 3062 to slide downwards within outer casing 305 and compress fixing rod 3061. This causes fixing rod 3061 to slide to the right within outer casing 305, pushing limiting block 303. Limiting block 303 then slides into the inner wall of base 304. Then, lift long plate 301, causing the bottom of long plate 301... The limiting rod 302 is perpendicular to the insertion hole on the top wall of the limiting block 303 and then inserted into the insertion hole. The limiting rod 302 passes through the limiting block 303 and the base 304 to form a stable connection, which is convenient to operate. By connecting it to the chiller 2 through the connecting block 5, when cleaning and replacing the cooling fan 6, the connecting block 5 can be removed from the chiller 2, and then the cooling fan 6 can be disassembled and installed. This reduces the phenomenon of operators working in the air, making the operation more convenient and facilitating equipment maintenance. Rotating bolt 4011 causes rack 4012 to move up and down within housing 402. Rack 4012 then drives gear 4013 to rotate, which in turn drives rack 403. This rotation drives block 404 to move synchronously to the sides and center within housing 402, allowing block 404 to open and close. When closed, block 404 is inserted into mounting slot 405. Opening block 404 then engages the inner wall of mounting slot 405, creating a secure connection. This facilitates the installation and removal of the cooling fan 6, improving maintenance efficiency.
