JIAERDA brazed plate heat exchangers are key components in windmill drive and hydraulic systems, and the ability to integrate system components is an important part of the value proposition of heat exchangers. Through the high-precision size design of the oil cooler to make it run in an intelligent system, we can maximize the efficiency of the system while achieving the best operating temperature. Our front-end technology and huge product portfolio enable us to provide the most compact and energy-efficient solutions on the market.
We provide the most compact solution for the water/glycol hybrid cooler of the frequency converter, the system integration with the generator cooling system, and the deionized water in the medium voltage frequency converter.
What is the basic structure principle of brazed plate heat exchanger:
The brazed plate heat exchanger is made of many stamped corrugated thin plates at a certain interval, sealed by gaskets around them, and laminated and compressed by a frame and a compression screw. The four corner holes of the plates and gaskets form the fluid distribution. The piping and the collection pipe, while reasonably separating the cold and hot fluids, make them flow in the flow channels on both sides of each plate, and heat exchange through the plates.
Brazed plate heat exchangers have been widely used in metallurgy, mining, petroleum, chemical, electric power, medicine, food, chemical fiber, paper, textile, shipping, heating and other sectors. They can be used for heating, cooling, evaporation, condensation, sterilization, and disinfection. , Waste heat recovery and other situations.
Design features of brazed plate heat exchanger:
High efficiency and energy saving: The heat transfer coefficient is 3000～4500kcal/m2·°C·h, which is 3~5 times higher than the heat efficiency of the shell and tube heat exchanger.
Compact structure: The plates of the plate heat exchanger are closely arranged. Compared with other types of heat exchangers, the plate heat exchanger occupies less area and space. The plate heat exchanger with the same area of heat exchange is only tube 1/5 of the shell heat exchanger.
Easy to clean and easy to disassemble: The plate heat exchanger is clamped by clamping bolts, so it is easy to disassemble and can be opened for cleaning at any time. At the same time, because the plate surface is smooth and clean, the turbulence is high and it is not easy to scale.
Long service life: The plate heat exchanger is made of stainless steel or titanium alloy plates, which are resistant to various corrosive media. The rubber pads can be replaced at will, and it is convenient to disassemble and repair.
Strong adaptability: The plates of the plate heat exchanger are independent components, and the process can be increased or decreased at will according to the requirements, with various forms; it can be applied to various different and technological requirements.
No liquid leakage, the plate heat exchanger seal groove is equipped with a liquid discharge channel, and various media will not collude. Even if there is a leakage, the medium will always be discharged.
The use of brazed plate heat exchanger in heat pump
1. Use as a low-temperature heat pump jet heat exchanger with increased enthalpy
Jet enthalpy is a new system composed of a jet compressor, jet enthalpy technology, and plate heat exchanger. The combination of these three technologies can provide high-efficiency performance. This is an organic whole, that is, the economizer and high-efficiency heat exchanger formed by the high-efficiency jet enthalpy-enhancing compressor, the plate heat exchanger, and the electronic expansion valve together constitute an energy-efficient jet system.
2. The brazed plate heat exchanger can be used as a water-fluorine heat exchanger
In the water fluorine system, although the brazed plate heat exchanger has the advantages of high-efficiency heat transfer, small temperature difference, and compact structure, it also has the shortcomings of easy structure blockage and freezing corrosion. Therefore, the brazed plate heat exchanger is suitable for better water quality. Closed systems, general groundwater, and tap water are not recommended to be used directly. When using in cold areas or as an evaporator, anti-freezing protection measures are also required. Guoxin's brazed plate heat exchanger has a reasonable design structure and no dead ends. Not easy to freeze, a thermostat can be added to directly sense the temperature to protect the efficient operation of the heat exchanger
