Design standard for plate and plate type of plate heat exchanger

We know that plate heat exchanger is made of stainless steel, industrial pure titanium or other materials. Usually, the plate is pressed into a variety of groove type or corrugated shape, which can increase the stiffness of the plate, to prevent the deformation of the plate under pressure, but also enhance the degree of turbulence of the fluid, increasing the heat transfer area. So what is the ideal plate type plate heat exchanger design should be like? Let's talk about it today.

Each of the four corners of the plate with a hole around the plate around the hole and pressure sealing gasket groove, and according to the needs of a gasket placed in the hole week slot, to allow fluid or prevent fluid into the surface between the role of the channel. If the number of the sheet in accordance with the requirements of heat exchanger are orderly arranged in the bracket, and with a fixed plate and a movable plate by a pressing screw pressed in the adjacent plates formed by fluid passages, and the orifice of the four corners of the plate. The gasket plate heat exchanger structure vary, the ultimate purpose of design the plate is to strengthen the heat transfer effect, increasing the stiffness of the panel, to improve the bearing capacity of plate heat exchanger.

The ideal type design, the heat transfer coefficient has larger heat transfer area, low pressure drop and high, but also has good rigidity, so that the plate is very thin in the fixed pressure plate. The pressure plate and clamping force under the action of mutual support, to resist the pressure on the balance of inner channel the impact of. For this reason, the reasonable distribution of the supporting points and the arrangement of reinforcing ribs should be considered in the plate design. The five part of a piece of sheet according to its function can be divided into the diversion part, heat transfer part and a sealing part, edge support and suspension positioning, which is the core part of the heat transfer plate structure, its structure mainly depends on the heat transfer characteristics of the medium, to determine the design according to the heat transfer and fluid mechanics.
