Asymmetric plate heat exchanger factory direct prices favorably asymmetric structural characteristics of plate heat exchangers: plate heat exchangers as an energy efficient heat transfer equipment in urban central heating project indirect, centralized or continuous heating , played a saving energy, saving equipment maintenance management costs, protect the environment, ensure the important role of people's lives to live and work, is indispensable urban central heating equipment. In recent years, with the growing scale of urban central heating, mostly for its operating characteristics or the temperature difference between the hot and cold side of the medium flow ranges, typically 2: 1ˉ3: 1, especially building air-conditioning heat exchangers, the typical Condition is a water temperature of 95 ℃ → 70 ℃, the secondary water temperature is 50 ℃ → 60 ℃ or 55 ℃ → 60 ℃, the temperature difference or the flow ratio of 2.5ˉ5, against such asymmetric conditions, China's few main plate heat exchanger manufacturers have developed a non-symmetrical plate heat exchanger, it is presented on the situation. 1. Two-sheet structural characteristics of fluid flow through different angular aperture size, large flow of fluid away bighorn hole, a small flow of fluid to go small square hole, the pressure drop of fluid flowing through the nozzle and two angle holes similar. 2. Diversion Area asymmetrical structure, that big, different small flow side of the fluid flow path geometry, the width of the low flow side flow passage is larger than the flow side of the flow channel width is narrow, shallow depth of the flow channel is larger than the flow side The total length of the flow path is longer than the high flow side. Thus, both sides of the deflector plate area has great asymmetry, two fluid pressure can drop along the diversion area is more balanced and more evenly distributed along the plate. 3. The heat transfer area on both sides of the cross-sectional area of ??the flow path are unequal (cross-sectional area ratio of 2: 1 or greater), the size and shape of the different chevron corrugated structure, shown in Figure 2. Obtuse angle of the corrugations can also be an acute angle; the two unequal fluid flow path cross-sectional area, when the flow of the two fluids ranging between two fluid plates can be close to or equal to the flow rate. Thus, greatly improving the heat transfer coefficient small flow side, so that the overall heat transfer coefficient greatly enhance and strengthen the heat transfer, saving heat transfer area.
