Pure nickel plate heat exchanger is a type of heat exchanger composed of pure nickel plates, used for heat transfer in high concentration and high temperature caustic alkali solutions. Here are the main characteristics and components of this heat exchanger:

Composition and Structure: The plate heat exchanger consists of a group of corrugated nickel N201 plates, with holes on these plates for the passage of two heat transfer media. The nickel plates are installed within a frame, with fixed plates and movable clamping plates, and are clamped together with clamping bolts. Sealing gaskets are installed on the plates to ensure the sealing of the fluid channels and guide the flow of fluids into their respective channels.

Design Principles: The flow rate, physical properties, pressure drop, and temperature difference of the fluids determine the number and size of the plates. The material of the plates and gaskets depends on the chemical properties and corrosion characteristics of the fluids. Different designs of corrugated plates improve turbulence and form support points to withstand pressure differences between media.

Installation Method: The metal nickel plates and movable clamping plates are installed on suspension beams and positioned by lower guide rods, with the rod ends fixed on support columns. If one or both of the fluids do not pass through the heat exchanger only once, the interface should be located on the fixed plate and the movable clamping plate.

Heat Transfer Efficiency: Properly matching the corrugated angles of the plates can improve the heat transfer efficiency per unit area, adjust the fluid resistance, save heat transfer area, and consequently reduce investment costs and shorten the investment payback period.

Material Selection: The plates of the pure nickel plate heat exchanger are made of pure nickel plates containing more than 99% nickel. Pure nickel possesses excellent electrical conductivity and corrosion resistance. It has a high melting point, and within the operating temperature range of the cathode, it may evaporate. It has sufficient heat evaporation and exhibits good mechanical workability and formability. This material can adapt to the working environment of high concentration and high temperature caustic alkali solutions, and has good corrosion resistance and high temperature stability.

The plate heat exchangers produced by our company strictly adhere to the standard NB/T47004-2009 for plate heat exchangers. The heat exchange plates are the core heat transfer components of plate heat exchangers. The main materials used in the heat exchange plates produced by our company are titanium and titanium alloys, as well as nickel and nickel alloys.

Fuel cells

A nickel plate heat exchanger for fuel cells is a crucial component used to regulate the temperature of the fuel cell system. It achieves this by conducting heat between nickel plates, transferring the heat generated within the fuel cell system to the external environment or vice versa. Here are some features and functions of the nickel plate heat exchanger for fuel cells:

Temperature Control: The stable operation of fuel cell stacks requires maintaining them within an appropriate temperature range. The nickel plate heat exchanger can adjust the flow of internal media to control the working temperature of the fuel cell system, ensuring that the system operates optimally.

Heat Transfer: During the operation of fuel cells, a significant amount of heat is generated and needs to be dissipated promptly to prevent the stack temperature from rising too high and causing system failure. The nickel plate heat exchanger efficiently transfers heat through conduction to the external environment or absorbs heat from the external environment to maintain system temperature balance.

Corrosion Resistance: The media within the fuel cell system may be corrosive, but pure nickel possesses excellent corrosion resistance, allowing it to operate stably in various chemical environments and ensuring the long-term reliability of the heat exchanger.

High-Temperature Stability: Fuel cell systems generate high temperatures during operation, and pure nickel exhibits excellent stability at high temperatures, maintaining structural stability and ensuring the normal operation of the heat exchanger.

Heat Efficiency: Well-designed and precisely manufactured nickel plate heat exchangers can significantly improve heat conduction efficiency, achieve efficient heat transfer and exchange, and enhance the energy utilization efficiency of fuel cell systems.
