Detailed introdution about Sondex plate heat exchanger.


The heat exchanger with the same angle hole size and width in the SONDEX series heat exchanger has 3-6 types of plates of different heights. Since the position of the corner hole and the aspect ratio of the plate heat exchanger affect the flow of fluids between the plates, it affects heat transfer. Sex, Therefore, SONDEX, a plate with different lengths and widths, meets the requirements of different thermal lengths. (Thermal length θ is the ratio of the temperature difference between the entrance and exit of a heat exchanger medium to the logarithmic average temperature difference of the heat exchanger medium under certain conditions, which is an important parameter of the ability to change the temperature of the heat exchanger.).


SONDEX also designed and produced twin plates with exactly the same size, only the corrugated depth of the plate, such as the S41 and S42 models SONDEX heat exchanger, with the same shape and angle hole size, but the S41 heat exchanger has a width of 5.4 mm. The S42 heat exchanger has a channel width of 6.9 mm. The wide channel is more suitable for the uneven flow of fiber, particle or high viscosity media and hot and cold media. Due to the wide and narrow channel heat exchangers, SONDEX plate heat exchangers can be designed to obtain the best inter-plate flow rate, thus achieving a good heat transfer effect.


Rich tablets make it easy for SONDEX to provide users with the best solution. For the same working conditions, SONDEX plate heat exchanger has higher thermal efficiency. The heat transfer area needed is more economical. This not only saves investment, but also can easily obtain more reasonable inter-plate flow rate, which reduces the corrosion and scaling speed of the plate, and extends the service life of the planter heat exchanger.
Each model of ONDEX has been carefully designed and rigorously tested.


Each type of plate is divided into two types: adult hard plate(TL) and villain soft plate(TK). The hard plate has high heat transfer efficiency, high fluid resistance, low heat transfer efficiency and low fluid resistance. The channel of plate heat exchanger can be a single soft plate channel, a hard plate channel, and a soft and hard plate channel can also be a mixture of the above channels. The optimal design of heat exchanger is obtained by the scientific ratio of channel.
The SONDEX plate heat exchangers all use the same side flow, because the design of the guide area is used at the entrance and exit of the plate, that is, the groove design of the chocolate island-shaped area at the exit of the corner hole. Ordinary linear guide slots play a uniform distribution role only for unilateral fluids, and this chocolate island-shaped groove design can balance the difference in flow resistance on each flow channel, so that the fluid on both sides can be obtained in each part of the plate. The relatively uniform fluid distribution state, Even the wider plate can evenly distribute the fluid between the plates, which fundamentally improves the traditional side-flow plate heat exchanger. Because the fluid distribution state between the plates is different and the flow dead angle causes the difference in the temperature distribution of the fluid along the path. And then bring about the adverse effects of reduced heat transfer efficiency; In addition, this part of the drainage area also participates in heat transfer at the same time, which improves the heat transfer area of the SONDEX plate heat exchanger;


Since the above chocolate island-shaped guide area design ensures the uniform distribution of fluids between plates, SONDEX adopts the same side-by-side diagonal flow form, making it easier for users to take over.
The international advanced design and production process make SONDEX plate heat exchanger is the best value for money product.


All SONDEX plate heat exchangers worldwide are made from 6 hydraulic presses at the Danish SONDEX plant, one of which has a capacity of 20,000 T and is the largest hydraulic compressor in Europe. It is specifically used to process large plates above DN400. Due to the large capacity of the press and advanced stamping technology, each SODNEX plate pressed is very flat and has no stress deformation at all. The surface roughness of the stamping sheet is the same as that of the original sheet, and it has a very high quality uniformity. The SONDEX sheet is fully in line with the quality requirements of the food hygiene board. The friction resistance of the fluid is reduced, the scale is not easy to be scaled, and the point erosion is not easy to occur, ensuring the stable and efficient operation of the SONDEX heat transfer equipment.


The difference of body distribution and flow dead angle results in the difference of temperature distribution of fluid along the course, which leads to the adverse effect of decreasing heat transfer efficiency. In addition, this part of the drainage area also participates in heat transfer at the same time, which improves the heat transfer area of the SONDEX plate heat exchanger;


Since the above chocolate island-shaped guide area design ensures the uniform distribution of fluids between plates, SONDEX adopts the same side-by-side diagonal flow form, making it easier for users to take over.


SONDEX plate heat exchanger adopts SONDER LOCK buckle visco-free gasket as the main seal. Compared with adhesive pads, non-adhesive pads have the advantages of easy installation and disassembly, repeatable use, and long life. The buckle connection designed by SONDEX is a row of protruding buckle structures that are evenly distributed on the gasket to overfit the hole in the corresponding position on the plate to ensure that the pad is not detached from the plate installation or use. In contrast to the suspension type visco-free gasket, the positioning part of the buckle gasket is not in contact with the fluid in the heat exchanger, thus preventing the positioning hook of the hanging gasket from being damaged due to fluid contact and long-term erosion., It affects the sealing ability. It can be said that the buttoning is the most advanced structure in the visco-free mat. However, due to the need for accurate coordination of the structure, a higher requirement is put forward for the machining accuracy of the plate and the gasket, that is, the position of all the small holes on the plate and all the buckles of the gasket must be accurate, otherwise the deviation of any one position will cause waste. The average manufacturer can not reduce the waste rate and therefore does not want to adopt this structure.


SONDEX plate heat exchanger gaskets can be used according to the user's different needs, NBR, EPDM, SILON fluorine rubber, etc.. In addition, SONDEX has introduced EPDM HT gaskets and NBRHT gaskets that can withstand high temperatures. EPDM HT high-temperature gaskets can withstand high temperatures of 180 °C. The temperature resistance of plate heat exchanger is greatly improved.
