Hout's marine plate heat exchangers introduction:
Plate heat exchangers are composed of main components such as the frame, heat transfer plate assembly, and clamping bolts.
The frame consists of a fixed clamping plate and a movable clamping plate, supported by the upper and lower guide rods, with a支柱 at the other end. Both media enter their respective channels, formed by corrugated plates, through the flange holes of the fixed (or movable) clamping plates. After heat exchange, the media exit through the flange holes of the fixed (or movable) clamping plates. The fixed clamping plate, movable clamping plate, pillar, and guide rods are all made of low-carbon steel. To cater to various user requirements, the frame design offers multiple configurations, primarily including double-support frame style and the commonly used floor-standing style.
Heat exchange plates are one of the core components of plate-type heat exchangers. The corrugated plates are formed by stamping, and their rational corrugation design increases the effective heat transfer area of the plates, causing turbulence as the fluid flows along the corrugations, enhancing the heat transfer process. Sealant pads are fitted in the sealing grooves of the corrugated plates, designed with a double-sealing structure and featuring signal holes. The type of sealant can be selected based on different fluids and operating temperatures.

*High thermal conductivity: The special corrugated design on the heat transfer plate enables intense turbulence in low fluid velocities, while the self-cleaning effect of the turbulence prevents the buildup of dirt, resulting in a thermal conductivity of 3-5 times that of shell-and-tube heat exchangers.
*Economic Efficiency: Compared to shell-and-tube heat exchangers with the same heat exchange capacity, it offers lower investment, operating costs, and maintenance costs.
*Adjustability: Simply add or remove panels to accommodate changes in the production process.
* Compact Structure: Only occupies 1/2 to 1/3 of the space of a tube-and-shell heat exchanger for the same heat exchange capacity.
Easier to clean and maintain.
*The sheet seal can be used with a non-adhesive fastener, reducing operation and maintenance costs, and facilitating repairs.
