Abstract
The invention discloses an inverted-V-shaped plate of a plate heat exchanger. The inverted-V-shaped plate comprises high corrugations and low corrugations, wherein the high corrugations and the low corrugations are arranged alternately, and the corrugation height ratio of the high corrugations to the low corrugations is 1:2 to 1:4. Meanwhile, pits are formed between the high corrugations and the low corrugations. The opening direction of the pits is the same as the direction of the high corrugations and the low corrugations. An opening of each pit is 3 mm in diameter and 0.6 mm in depth. According to the inverted-V-shaped plate, the heat exchange performance of the high corrugations and the low corrugations is good; the number of contact points of adjacent plates is reduced thanks to the existence of the low corrugations, and the inverted-V-shaped plate has the characteristic of reducing resistance. In addition, through the arrangement of the pits, local turbulent flow is generated when fluid flows through the pits, so that fluid heat exchange is enhanced secondarily, and the heat exchange capacity of the fluid is improved. Through the addition of the pits, the heat exchange area of the heat exchange plate is increased to some extent, and the overall heat exchange capacity is increased.
