Description

Technical Field

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

[0002] Water-cooled chillers are mainly suitable for plastic and mechanical processing. They can accurately control the temperature of plastic forming molds to shorten the molding cycle and accelerate product shaping. This series uses the principle of heat exchange for cooling, can quickly cool down, has stable temperature control, and is not affected by environmental factors. It is an indispensable configuration equipment in modern industry. Water-cooled chillers mainly complete the refrigeration cycle through four basic components: compressor, condenser, expansion valve and evaporator. These four parts complete the continuous change of the refrigerant state through compression, condensation, throttling and evaporation processes, thereby realizing heat absorption and release. During the refrigeration process, the refrigerant absorbs heat from the water in the evaporator and evaporates into a gaseous state, which is then sucked in and compressed by the compressor; afterwards, the gaseous refrigerant condenses into a liquid in the condenser, releasing heat to the cooling water, and finally returns to the evaporator after reducing the pressure and cooling through the expansion valve to complete a refrigeration cycle.

[0003] However, the shell and tube condenser in the existing water-cooled chiller has a complex internal structure, and it is easy for dust and debris to accumulate on its surface, affecting the cooling effect. As the use time increases, these dust and debris accumulate more and more, resulting in a gradual decrease in the heat dissipation effect of the shell and tube condenser. How to clean it to maintain a good heat dissipation effect? ​​In the installation process of the existing water-cooled chiller, the unit is generally installed by bolting. Although this traditional method does ensure the stability and safety of the equipment to a certain extent, it also brings a series of operational efficiency problems and maintenance inconveniences, resulting in low efficiency and poor practicality during the installation and maintenance process.
