[0025] PCB factories have many complex production processes. They need to keep the temperature constant in all stages of production, which requires heating and cooling to keep the temperature stable. Most manufacturers currently use water chillers for cooling. The water chillers cannot be stopped during production and continuous operation consumes a lot of electricity. Strict cost control is an urgent need for improvement for existing PCB factories. The current winter production equipment cooling demand: 2600KW / According to the water chiller COP4.6, the required power is ≈550KW, and the daily power consumption cost is: 550*0.65%*24H*0 .65 yuan / kWh = 5577 yuan, monthly electricity cost 167,000 yuan; using natural cooling device, when the outdoor temperature is lower than 5℃, the production demand is 2600kw, and the chiller does not need to run under the condition of 1℃ temperature difference of natural cooling device, thus saving the cost required for unit operation; the plate heat exchanger is a heat exchange plate with a certain corrugated shape pressed from thin metal plate, and the required heat exchange area is calculated by cooling efficiency, cooling water temperature, flow rate and other parameters and required cooling capacity; according to the calculation method of multiplying the heat exchange area by a coefficient of 1.15, the final required heat exchange area is obtained (standard specifications are required The number of heat exchanger plates) is then stacked and fastened with a clamping plate 120 and bolts. A slender rectangular channel is formed between each plate. Heat exchange is carried out through the semi-bent wheel plate. The working fluid flows through the narrow and tortuous channel formed between the two plates. The cold and hot fluids pass through the flow channel in turn. There is a sandwich plate in the middle to separate the fluids. Heat exchange is carried out through this plate. The structure and heat exchange principle of the plate heat exchanger determine that it has the characteristics of compact structure, small footprint, high heat transfer efficiency, large operational flexibility, wide application range, and easy installation and cleaning. The working principle of the device is to use the water inlet and outlet connection of the heat exchanger cold end The cooling tower and the hot end connection equipment output the increased temperature cold water after heat exchange. This effective connection takes advantage of the high heat transfer efficiency of the channels between the heat exchanger plates to achieve the cooling effect; the temperature detection unit is used to effectively connect the heat exchanger and the chiller to achieve the temperature that meets the process setting conditions and the chiller does not work, thereby achieving the purpose of energy saving; by adding a natural cooling device, it is possible to generate cost-free cooling according to the outdoor temperature changes under the demand for 2600Kw of cooling capacity, and achieve the purpose of 0 investment when the outdoor temperature and cooling demand indicators meet the design parameter requirements, ultimately achieving the energy saving goal of reducing monthly electricity bills by approximately RMB 167,000.
