Electroplating Solution Cooling and Heating Constant Temperature Unit

Electroplating Solution Cooling and Heating Constant Temperature Unit

Unit Introduction

1. Electroplating: Electroplating is the process of applying a thin layer of other metals or alloys onto the surface of certain metals using the principle of electrolysis. During electroplating, an electrolyte containing ions of the plating metal is typically used to prepare the electroplating solution. The metal product to be plated is immersed in the electroplating solution and connected to the negative terminal of a DC power supply as the cathode, while the plating metal serves as the anode and is connected to the positive terminal. A low-voltage direct current is applied, causing the anode metal to dissolve into the solution as cations, which migrate to the cathode. These ions gain electrons at the cathode and are reduced to metal, coating the metal product that requires plating.

2. Anodizing: Anodizing is a treatment process where metal or non-metal products act as an anode in a specific electrolyte under particular working conditions. Through the action of direct current, an anti-corrosion oxide film is formed on their surface.

3. The temperature of the electroplating and anodizing solutions is controlled by the electroplating solution cooling and heating constant temperature unit. The temperature is adjustable, maintaining the solution within the required temperature range for electroplating and anodizing, thereby improving the yield rate of electroplated and anodized products.

4. To meet industry requirements for corrosion resistance, heat exchangers made of titanium or 316 stainless steel are used. Temperature control enhances productivity and product quality. In the electroplating, anodizing, and electrophoretic industries, the electroplating solution cooling and heating constant temperature unit helps stabilize metal and non-metal ions, allowing metal ions to quickly adhere to electroplated, anodized, and electrophoretic products. This reduces the number of electroplating and anodizing cycles and increases productivity.

Unit Features:

1. Stable Performance: The unit employs multiple compressors operating in parallel, each with its own independent refrigeration circuit, including completely separate evaporators and condensers. All compressors are controlled by a unified microcomputer system, which manages their startup and shutdown individually, ensuring no interference between them. Additionally, the unit uses genuine original components, resulting in an extremely low failure rate. These factors guarantee stable performance and continuous long-term operation without the need for additional backup units.

2. Energy Efficiency: The use of multiple small and medium-power compressors operating in parallel minimizes grid interference during startup and shutdown. The unit automatically determines the number of compressors to activate based on load changes, ensuring optimal working conditions and effectively saving energy.

3. Long Service Life: The evaporator and condenser are designed very rationally and are positioned above the compressor. Throughout operation, most of the oil remains within the compressor, ensuring excellent lubrication.

4. Scientifically designed with optimized combinations of technical parameters, the unit features advanced and reasonable performance indicators. It can also be customized according to user requirements to provide products with different performance specifications.

Unit Refrigeration Principle

The compressor operates, converting low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant, which enters the condenser. Part of the heat from the refrigerant in the condenser is expelled by external cooling water or cooling fans. After releasing heat, the refrigerant liquefies into a high-temperature, high-pressure liquid and flows out. It then passes through a dryer filter for drying and filtration before entering the expansion valve for throttling (a rapid cooling process) and pressure reduction. The refrigerant liquefies into a low-temperature, low-pressure liquid and enters the evaporator for heat exchange. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding medium (electroplating solution) in the evaporator. During the heat absorption process, the refrigerant temperature remains constant while its volume changes. After absorbing heat, the low-pressure liquid refrigerant vaporizes into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. It is compressed into a high-temperature, high-pressure gas and returns to the condenser, completing the refrigeration cycle. This effectively cools the electroplating solution, maintaining it at the desired temperature.

Unit Heating Principle

Based on the refrigeration principle, the compressor operates, converting low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gas. The refrigerant passes through a four-way valve and a liquid storage tank before entering the condenser. The heat from the condenser is utilized to heat water in a tank, with water temperatures reaching up to 90°C. After releasing heat, the refrigerant liquefies into a high-temperature, high-pressure liquid and flows out. It then passes through a dryer filter for drying and filtration before entering the expansion valve for throttling (a rapid cooling process) and pressure reduction. The refrigerant liquefies into a low-temperature, low-pressure liquid and enters the evaporator for heat exchange. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding medium (water or oil) in the evaporator. During the heat absorption process, the refrigerant temperature remains constant while its volume changes. After absorbing heat, the low-pressure liquid refrigerant vaporizes into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. It is compressed into a high-temperature, high-pressure gas and returns to the condenser, completing the air-source heat pump cycle. This effectively heats the electroplating solution, bringing it to the desired temperature for electroplating and anodizing.
