Free swimming pool, bath center, landscape water engineering solutions, plate heat exchanger to heat transfer efficiency (than the traditional shell and tube heat exchanger of 2 to 4 times), energy saving, economical, compact, and easy disassembly advantages, has been widely used in chemical, electric power, metallurgy, food, petroleum, pharmaceutical, shipbuilding, electronics, textile, paper and other industrial sectors, while in the urban central heating and heat recovery projects where it has been widely adopted. My company manufacture plate heat exchanger has been the State Science and Technology Commission, Ministry of Machinery, Ministry and other seven ministries as the sixteenth installment of energy efficient mechanical and electrical products in the country. Today, I plant has tons of special presses and the corresponding plate mold to shape, materials are imported stainless steel plate, gaskets manufactured using US joint venture Pike pads. The production of plate heat exchanger heat exchanger products have passed national product quality supervision and inspection center of the test and evaluation and the Guangdong Provincial Science and Technology Appraisal, the main technical indicators have reached the advanced level, and in many ways, with similar foreign products comparable level. Plate heat exchanger structure in Figure 1, fixed clamping plate 2, active pressing plate 3, the upper guide rod 4, export 5, the clamp bolt 6, the guide rod 7, the heat exchange plate 8, the front pillar Note: Figure the red hot fluid, blue cold fluid, its color changes reflect changes in temperature during the heat exchanger plate heat exchanger heat transfer efficiency characteristics of the design of the corrugated plate with a high thermal conductivity of the target membrane, plate corrugations formed by the special channel (see Figure) at a very low flow rate of the fluid can occur under strongly disturbed flow (turbulent flow), there are self-cleaning effect of disturbed flow in order to prevent fouling and thus generate high heat transfer efficiency. Generally speaking, the plate heat exchanger heat transfer coefficient K value in the range of 3000 ~ 6000W/m2.oC. This indicates that only the plate heat exchanger shell and tube heat exchanger required area of ??1/2 to 1/4 of the heat exchanger can achieve the same effect. The use of safe and reliable seal between the plates of the two devices designed seal, while a signal hole, in the event of leakage, can be discharged outside heat exchanger, which prevents two kinds of mixed media, also played a security alarm role. Resourcefulness as heat exchanger plates easily removed by adjusting the number of heat exchanger plates or change process can get the most suitable heat transfer and capacity. Just use the intermediate frame heat exchangers, heat exchanger plate member can have a variety of unique functions. This provides the user at any time to change the capacity and the heat transfer coefficient K value change or add a new function is possible. In favor of the use of low temperature heat source because the two media are almost full countercurrent flow, and high heat transfer plate heat exchanger minimum difference between the two media can be achieved 1oC. Use it to recover waste heat or the use of low temperature heat source is the best equipment. Small footprint, easy to maintain the structure of the plate heat exchanger is extremely compact, equal in heat transfer conditions, the less space is only a shell and tube heat exchanger 1/2 to 1/3. Image converter shell and does not need to set aside as too much space to pull out the tube bundle overhaul. The plate heat exchanger need only release the clamping screw can be in the range of 100% of the original space in contact with the surface of the heat exchanger plates down and disassembly easy. Less pressure loss coefficient of heat transfer in the same conditions, the plate heat exchanger flow rate through the rational choice, the resistance loss can be controlled in a shell and tube heat exchanger 1/3 range. Heat loss is small and compact due to the small size, the heat exchanger surface area is small, and thus heat loss is small, usually no longer necessary equipment insulation. Plate heat exchanger cooling water is small due to the geometry of the flow channel due to two kinds of liquids and has high thermal efficiency, the amount of cooling water can be greatly reduced. In turn, reduces the pipes, valves and pumps installation costs. Investment, lower operating costs at the same premise of heat transfer, plate heat exchangers and shell and tube heat exchangers compared to the heat transfer area, covers, fluid resistance, cooling water and other projects to reduce the value of such investment in equipment infrastructure investment, cost of greatly reduced power consumption, particularly when the need to use expensive materials, due to the high efficiency and the thin plate, the device is more economical.
