The brazed plate heat exchanger is a new type of high-efficiency heat exchanger that is composed of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the various plates to exchange heat through the half-plates. Compared with conventional shell and tube heat exchangers, its heat transfer coefficient is much higher under the same flow resistance and pump power consumption. It has a tendency to replace shell and tube heat exchangers within the applicable range.
d=r >Application scope:
This model of brazed plate heat exchanger is mainly used for refrigeration evaporator condenser and oil cooling steam heating with relatively large flow rate.

Welded plate heat exchanger
d=r >r series welded plate heat exchanger
/>(hereinafter referred to as the heat exchanger) is a combination of the advantages of the tube-type heat exchanger with higher temperature and pressure resistance and the high heat transfer efficiency of the detachable plate heat exchanger. It has the advantages of light weight, high heat transfer coefficient, resistance It has the advantages of being small, not easy to scale, and has great adaptability. In addition, the fully welded plate heat exchanger is a plate heat exchanger with a wide flow channel. It is suitable for process requirements with small temperature differences and large flow rates, and is suitable for fluids with particulate matter and high viscosity. The heat exchanger is mainly composed of plates, end plates, inlet and outlet pipe boxes and heads.

d=r >Product introduction:
The number of plates for the plate heat exchanger is first selected by a microcomputer according to the process conditions of each working condition. The frame is composed of splints, guide posts, fixing bolts, etc. Each plate has an angular hole connected with the corresponding pipe to alternately distribute the two fluids to the respective flow channels between the plates. The two fluids always exchange heat energy under pure countercurrent conditions, causing the thin fluid flowing between the plates to produce a turbulent state and forced convection heat transfer. At the same time, the thermal resistance of the liquid film is reduced, making the overall heat transfer coefficient of the plate heat exchanger particularly high and the resistance drop very low. Many support points are formed between the heat transfer plates, making it sufficient to withstand the pressure of the liquid. < The selection engineer uses microcomputer software to accurately provide equipment selection under various working conditions and calculations of the model, and the verification parameter table determines the overall dimensions and model of the equipment based on the operating pressure.

Volume plate heat exchanger
d=r >Volume type heat exchanger uses cold and hot fluids to alternately flow through the heat storage in the regenerator. The heat exchanger is a volumetric heat exchanger in which the cold and hot fluids are separated by solid partition walls and exchange heat through the partition wall. Therefore, it is also called a surface heat exchanger.
d=r >According to different heat transfer methods, it can be divided into three categories: hybrid volumetric heat exchanger, thermal storage volumetric heat exchanger and dividing wall volumetric heat exchanger
d=r >One type The volumetric heat exchanger is mainly composed of a body, a steam coil assembly, a steam inlet and outlet, and a hot and cold water inlet and outlet. In order to prevent corrosion on the surface of the body, the utility model sprays an anti-corrosion alloy layer on the surface and brushes the alloy layer. The paint layer is formed and the original pipe box steam coil is eliminated and the steam coil is directly connected externally through the flange, so that the utility model has the characteristics of simple and reasonable structure, long service life, good heat exchange effect and energy saving.
d=r >A volumetric heat exchanger which consists of a body, a steam coil assembly inside the body, a steam inlet and outlet, a cold water inlet and a hot water outlet. It is characterized by the inner surface of the body. A layer of high-temperature melted anti-corrosion alloy layer is sprayed on it. Volumetric heat exchangers are made by enlarging the volume of ordinary floating coil heat exchangers. Mainly used in hot water supply systems. Generally, an automatic temperature control device should be installed at the outlet to ensure the appropriate water supply temperature for bathing water or sanitary hot water. In addition to having all the advantages of ordinary floating coils, it can also store a certain amount of hot water to ensure timely supply of hot water. < -r >Shanghai Jiangxing Chemical Equipment Co., Ltd.
