The invention discloses a chevron corrugated plate. The chevron corrugated plate comprises a corrugated plate body which is in a square structure, wherein the four corners of the corrugated body are provided with fluid inlet-outlets, locating gaps are formed in the middle of the top and bottom of the corrugated plate body, and a rectangular frame is arranged in the middle of the corrugated plate body and is internally provided with chevron waves; gaps provided with inclined waves are formed between the upper and lower parts of the rectangular frame and the fluid inlet-outlets, and diversion trenches are arranged at one ends of the two inclined waves. Certain inclined angles between the flow direction of fluid and waves are formed to cause zigzag flow and strengthen the flowing disturbance. The waves of chevron corrugated plate slices are in the chevron shapes; the adjacent plate slices are combined to form multi-point contact in such a way that the chevrons are oppositely combined up and down when the plate slices are installed in a heat exchanger, therefore higher pressure can be borne, the heat transfer performance is better, and the highest heat efficiency can reach up to above 95%.
Description
technical field [0001] The invention relates to an accessory of a plate heat exchanger, in particular to a herringbone corrugated plate. Background technique [0002] Plate heat exchangers can be used to handle liquids from water to higher viscosity, and can be used for heating, cooling, condensation, evaporation and other processes. In the chemical industry, it is used for cooling ammonia water, industrial wastewater treatment, cooling synthetic resin, etc. In the food industry, it is widely used for heat sterilization and cooling of food, etc. Because the plate heat exchanger has the following advantages: high overall heat transfer coefficient, compact structure, low cost, easy to use, and can realize heat exchange in various media, it is widely used. With the continuous updating of technology, the existing corrugated plates have been difficult to meet the requirements of complex industrial heat exchange. Contents of the invention [0003] In order to solve the above t...
