Plate heat exchanger
Disassembleable plate heat exchangers are currently the most popular home heat exchangers, especially in winter. In cold climates, if the house doesn't have heating, using this type of disassembleable plate heat exchanger is very practical. A good disassembleable plate heat exchanger can bring endless heat to the room, providing warmth for people and for drying clothes, etc.

Basic Introduction
The dismountable plate heat exchanger is currently the most popular household heat exchanger, especially in winter. In cold climates, if the house does not have heating, using this type of dismountable plate heat exchanger is very practical. A good dismountable plate heat exchanger can bring endless heat to the room, providing warmth for people and drying clothes, etc.
Plate heat exchangers are dismountable heat exchange devices composed of many corrugated heat transfer plates, arranged at a certain interval, and pressed together by rubber gaskets. When the plates are assembled, two sets are arranged alternately. The plates are fixed together with rubber seals, which prevent liquid leakage and form narrow mesh-shaped flow channels between the two plates. The heat exchange plates are pressed into various corrugated shapes to increase the heat exchange area and rigidity, and to allow the liquid to form turbulence at low flow rates to achieve enhanced heat transfer. The four corner holes on the plate form the liquid distribution pipe and collecting pipe. The two heat exchange media flow into their respective channels and form countercurrent flow through each plate to exchange heat.
Technical Characteristics
Excellent Flow Guiding Design
The inlet distribution area of the plates is designed with streamlined guide grooves, which have the effect of reducing the difference in flow resistance on different flow channels, so that the fluid is evenly distributed in the plate heat exchange area, thus avoiding the decrease in heat exchange efficiency, pitting, and scaling caused by uneven flow distribution and stagnant flow areas. For plates with a larger width, equipotential pressure grooves are also added, so that the resistance formed by the intersection of the streamline guide groove and the equipotential pressure groove is very small, and a grid-like inlet distribution area with a near-perfect flow averaging effect is formed. At the same time, the distribution area also plays the role of quickly forming turbulent and strong heat exchange, making the distribution area participate in heat exchange in advance, effectively increasing the heat exchange length and reducing the heat exchange area.
Advanced Positioning Structure
The plates use a dovetail groove-shaped hanging positioning system. This system has three functions:
Hanging: The plates are hung on the guide rod, allowing them to slide freely along the upper guide rod;
Positioning: The plates are accurately positioned up, down, left, and right;
Locking: The newly designed dovetail groove folding edge allows the plates to automatically lock each other during clamping, ensuring that all plates are accurately aligned under any installation conditions, avoiding deviations caused by human factors. Using the concave-convex groove positioning technology of the four corners of the plates ensures that the plates interlock and will never misalign during assembly.
