Tube heat exchanger

The casing heat exchanger is a carrier that transfers part of the heat of the hot fluid to the water. It uses high-efficiency screw-shaped copper tubes and wraps the treated galvanized steel pipes to realize the process of refrigerant water-filling, allowing high-temperature refrigerant gas to be fully Contact with water to achieve better heat transfer effect. Advantages of casing heat exchanger: ①The structure is simple, and the heat transfer area can be increased or decreased freely. Because it is composed of standard components, no additional processing is required for installation. ②High heat transfer efficiency. It is a pure counter-flow heat exchanger. At the same time, a suitable cross-sectional size can be selected to increase the fluid velocity and increase the heat transfer coefficient of the fluid on both sides, so its heat transfer effect is good. During liquid-liquid heat exchange, the heat transfer coefficient is 870 ～ 1750W / (m2 · ℃). This is especially suitable for the heat exchange of fluids with high pressure, small flow rate and low heat transfer coefficient. The disadvantage of the tube-type heat exchanger is that it occupies a large area; the metal consumption per unit heat transfer area is large, which is about 5 times that of the shell-and-tube heat exchanger; there are many tube joints, which are easy to leak; and the flow resistance is large. ③Simple structure, wide working adaptability range, convenient increase and decrease of heat transfer area, both sides of the fluid can increase the flow rate, so that both sides of the heat transfer surface can have a higher heat transfer coefficient, is the metal consumption per unit heat transfer surface Large, in order to increase the heat transfer area and improve the heat transfer effect, various types of fins can be added on the outer wall of the inner tube, and a scraping film disturbance device is added in the inner tube to adapt to the heat exchange of high viscosity fluid. Characteristics of fin heat exchanger: 1. The heat transfer efficiency is high. The disturbance of the fins to the fluid causes the boundary layer to continuously rupture, which has a large heat transfer coefficient. At the same time, because the separator and the fins are thin and have high thermal conductivity, the plate-fin type is replaced. The heater can achieve very high efficiency. 2. Compact, because the plate-fin heat exchanger has an extended secondary surface, its specific surface area can reach 1000㎡ / m³ 3. Lightweight, the reason is compact and mostly made of aluminum alloy. Now steel, copper, composite materials, etc. have also been mass produced. 4. Through the arrangement and combination of flow channels, it can adapt to different heat exchange conditions such as countercurrent, crossflow, multi-stream and multi-pass flow. Through the combination of series, parallel and series-parallel between units can meet the heat exchange needs of large equipment. In the industry, it can be shaped and mass-produced to reduce costs and expand interchangeability through building block combination.
