Description

Technical Field

[0001] The utility model relates to the technical field of air-cooled water chillers, in particular to an air-cooled water chiller. Background Art

[0002] Air-cooled chillers, as a model in the chiller series, are designed to use the refrigeration function of the compressor to cool normal temperature water to a specific temperature, thereby providing enhanced cooling effect for molds or machines. The device can be used as a stand-alone unit, and its heat dissipation mechanism adopts a built-in fan design. The operation of air-cooled chillers depends on three closely connected systems: the refrigerant circulation system, the water circulation system, and the electrical automatic control system. First, the refrigerant circulation system is the core part of the air-cooled chiller. The system drives the refrigerant to flow in a closed cycle through the compressor, thereby realizing heat transfer and temperature control. The refrigerant absorbs the heat of the water in the evaporator, causing the water temperature to drop, and then enters the condenser after being compressed by the compressor, releasing heat, and finally returns to the evaporator to form a closed loop. Secondly, the water circulation system is responsible for transporting the water to be cooled to the evaporator and exchanging heat with the refrigerant. The water pump draws water from the water tank and sends it to the evaporator, where it comes into contact with the low-temperature refrigerant to reduce the water temperature. The cooled water is then sent back to the mold or machine to achieve the cooling effect;

[0003] Air-cooled chillers are used for cooling the molding molds of plastic processing machinery. They can greatly improve the surface finish of plastic products, reduce surface marks and internal stress of plastic products, prevent products from shrinking and deforming, facilitate the demoulding of plastic products, accelerate product shaping, and thus greatly improve the production efficiency of plastic molding machines.

[0004] At present, air-cooled chillers generally adopt an integrated design mode, which exposes certain limitations in the application of production workshops. Especially in an environment with many equipment and limited available space, it is often difficult to find a suitable location for the integrated machine to be placed and used, thus affecting its practicality. In addition, when dissipating heat and cooling, existing air-cooled chillers usually rely on fans to cool the condenser. However, the speed of these fans often cannot be adjusted in real time according to the temperature changes of the condenser, which not only reduces the energy efficiency ratio, but also increases energy consumption, which is not energy-saving and environmentally friendly.

[0027] In this embodiment, specific reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The plug-in assembly 7 includes a lower plate 701 and an upper plate 702. The lower plate 701 is installed at the port of the lower shell 1, and the lower plate 701 is located directly below the upper plate 702. A fixing groove 703 is provided on the outer wall of the lower plate 701. There are multiple groups of fixing grooves 703 and they are respectively located on the outer wall of the lower plate 701.

There are multiple groups of limiting plug rods 704 and they are respectively located on the outer wall of the upper plate 702.

[0028] Among them, the control panel 8 is connected to the Southern pipeline pump 3, the Copeland compressor 4, the high and low pressure controller 6, the pressure gauge 9, the temperature sensor 13 and the heat dissipation fan 12 through wires, and the connection method is electrical connection, so that the device is powered on, the Southern pipeline pump 3 is located on one side of the Copeland compressor 4, the shell and tube evaporator 5 is located on one side of the Copeland compressor 4, the Copeland compressor 4 is provided with multiple groups and are respectively located on the inner wall of the lower shell 1, the high and low pressure controller 6 is located directly above the shell and tube evaporator 5, the pressure gauge 9 is provided with multiple groups and are respectively located on the outer wall of the upper shell 2, the fixed shell 11 is provided with two groups and are respectively located on the outer wall of the upper shell 2, the connection between the fixed shell 11 and the upper shell 2 is a connecting structure, the condenser 10 is located directly below the heat dissipation fan 12, and the condenser 10 is a V-shaped fin structure, the temperature sensor 13 is located on one side of the condenser 10, and when the temperature of the condenser 10 is higher, the speed of its heat dissipation fan 12 is also faster.

[0029] When the air-cooled chiller of this scheme is working, the lower plate 701 is installed at the port of the lower shell 1, and a fixing groove 703 is opened on the outer wall of the lower plate 701. A limit rod 704 is installed on the inner wall of the fixing groove 703.
