Although the electric vehicle circulating cooling device is relatively hot, but Wuxi Guanya for its quality problems have been very important, baffle plate is one of the smaller part, but it is better to understand clearly or suggest that everyone understand clearly.
Spiral baffle plate is divided into single spiral baffle plate and double spiral baffle plate has the advantages of good heat transfer, pressure reduction, uniform flow, but the disadvantage is difficult to manufacture, the design point is spiral angle 5-45 degrees, suitable occasions when pressure drop is limited, easy to scale occasions.
The advantages of the baffle bar are excellent support, uniform flow, reduced pressure, and basically no vibration. The disadvantage is low heat transfer effect. The tube arrangement can only be 45 and 90 degrees. It is suitable for low pressure drop gas condensation and heat transfer.
Single-bow baffle can achieve relatively large cross-flow, the disadvantages are high pressure drop, and the window tube bundle is prone to vibration; the design point is that the baffle circular gap rate between 17% and 35%, baffle spacing between 0.2-1.0 times the shell diameter, this type of baffle is suitable for most occasions.
NITW baffle window does not distribute pipes, pipe support is perfect, does not cause tube bundle vibration, electric vehicle circulating cooling device reminds everyone that the shortcomings are the same shell diameter, less pipes, the need for large shell diameter, with a 15% baffle circular defect rate, suitable occasions are limited by gas vibration and pressure drop.
Double bow baffle has the advantage of lower pressure and better avoidance of vibration, but the disadvantage is large window flow area, the design point is 5% – 30% of the circular defect rate, the default two rows of tubes overlap, suitable for occasions when vibration and pressure constraints heat exchanger (compared to a single bow baffle).
The nest type has the advantages of superior support, uniform flow and low pressure, but its disadvantage is that the heat transfer effect is worse than that of the nest type. Egg frame support is good, manufacturing economy, the disadvantage is high temperature stress deformation, design basically no requirements.
There are many kinds of baffles in the circulating cooling device of electric vehicles. Similarly, other accessories are the same. But the choice of accessories in the circulating cooling device of Wuxi Guanya electric vehicles uses brand accessories, which can ensure the operation of the circulating cooling device of electric vehicles to a certain extent.
