Product Definition
A double-plate heat exchanger unit is a high-efficiency heat exchange system that uses a double-plate heat exchanger as the core heat exchange element and integrates auxiliary equipment such as circulating pumps, valves, instruments, and control systems.It achieves rapid heat transfer by having hot and cold media flow counter-currently in the channels of a plate heat exchanger, utilizing the high thermal conductivity of the metal plates.It is widely used in scenarios such as heat recovery and temperature regulation, and is a key device for achieving efficient energy conversion in industrial production and civil buildings.
Product Features
Corrugated stainless steel plates are used as the heat exchange medium, forming dense flow channels between the plates.With a large contact area between hot and cold media and uniform flow velocity, the heat transfer coefficient is 30%-50% higher than that of traditional shell-and-tube heat exchangers. Heat loss is small and operating energy consumption is reduced by 15%-25%, meeting the requirements of energy conservation and environmental protection.
The double-plate heat exchanger design significantly optimizes space utilization. With the same heat exchange area, the unit volume is only 1/3 to 1/5 of that of a shell-and-tube heat exchanger, and it is also lighter.It is easy to install in small spaces (such as basements and equipment rooms), reducing civil construction costs.
It supports flexible adjustment of operating parameters according to actual working conditions (flow rate, temperature, pressure), and can achieve dynamic load matching by controlling the speed of the circulating pump through frequency conversion.The number of plates can be increased or decreased as needed to adapt to different heat exchange capacity requirements. Applicable media include various fluids such as water, ethylene glycol solution, and oil.
The plate heat exchanger adopts a bolt-fastened structure, and the plates can be removed by loosening the bolts.It facilitates cleaning of dirt, inspection of wear and tear, or replacement of damaged plates. The maintenance process requires no complicated tools, has short downtime, and reduces operation and maintenance costs.
The core component plates are made of corrosion-resistant materials such as 304/316L stainless steel and titanium alloy, which have strong anti-scaling and anti-corrosion capabilities.The unit is equipped with safety devices such as pressure protection, temperature monitoring, and leakage alarm. It operates at stable pressure and has a service life of 10-15 years under normal maintenance.
Product Functions
Core function of heat exchange
It enables efficient heat transfer between two media, such as transferring industrial waste heat to domestic water or converting high-temperature water from centralized heating networks into water at the appropriate temperature required for indoor heating.
Precise temperature control
Through an integrated temperature sensor, electric regulating valve, and PLC control system, the inlet and outlet temperatures of the medium are monitored in real time, and the medium flow rate is automatically adjusted.Ensure that the output temperature remains stable within the set range (accuracy ±1℃) to meet the temperature requirements of different scenarios.
Pressure stabilization and protection
Equipped with a pressure stabilizing pump, safety valve and pressure transmitter to maintain stable pressure in the system and avoid equipment damage caused by excessively high or low pressure.When abnormal pressure occurs, the system automatically alarms and triggers a shutdown protection mechanism.
Media Filtration and Purification:
Built-in ≥50μm filter intercepts impurities and prevents clogging, ensuring heat exchange efficiency and extending component life; touch screen provides real-time parameter monitoring and intelligent diagnostics, and some models support IoT remote operation and maintenance for convenient operation.
