When using multiple plate heat exchangers, we must pay attention to control the distance between them and keep a certain distance, so as to facilitate the heat exchange between various equipment. In order to improve the overall heat transfer efficiency, what is the role of plate heat exchanger spacing?
1. The structure is tight, the coarseness is high, and the steel consumption is low.
2. Greatly save steel, and there is no frame for plate heat exchanger.
3. The heat transfer resistance of the thin plate in the thickness direction is very small, which can effectively improve the overall heat transfer efficiency of the equipment.
4. The plate heat exchanger spacing increases the heat transfer area of plate heat exchangers and disturbs the fluid, resulting in the increase of flow velocity, the continuous change of flow direction and the greatly thinning of fluid stagnant boundary layer, thus strengthening the heat transfer.
5. Because the internal honeycomb structure does not need to be welded, and the finalized products and stamping dies can be reused, the honeycomb plate stamping can realize automation and batch production, reduce the comprehensive manufacturing cost, improve the production efficiency and save investment.
Therefore, if it is necessary to use multiple plate heat exchangers, then the plate heat exchanger spacing must be kept well. This is of great significance for the improvement of heat exchange efficiency, so it is necessary to keep good spacing in the usual installation and use.
