main feature:
1, to improve the heat transfer effect and reduce pressure loss.
2, heat exchange tubes using high quality copper tube heat exchange area, product volume is small.
3, the use of advanced expansion joint process, stable and reliable quality and convenient maintenance, applicable to all kinds of hydraulic transmission machinery.
4, the product line is complete, the size is complete.
The tube heat exchanger is a partition wall heat exchanger that is a heat transfer surface that is enclosed in the wall of the tube bundle in the housing.
This kind of heat exchanger has a simple structure and reliable operation.
It can be made of various structural materials (mainly metal materials) and can be used under high temperature and high pressure. It is currently the most widely used type.
From the shell, heat transfer tube bundles, tube plates, baffles (baffles) and tube boxes and other components.
Most of the shell is cylindrical, with a tube bundle inside, and both ends of the tube bundle are fixed on the tube plate.
Two kinds of hot and cold fluids for heat exchange, one flowing in the tube, called tube-path fluid; the other flowing outside the tube, is called shell-side fluid. In order to increase the coefficient of heat transfer of the fluid outside the tube, several baffles are usually installed in the housing.
The baffle can increase the velocity of the shell-side fluid, forcing the fluid to cross the tube bundle several times in a defined distance, increasing the degree of fluid turbulence.
The heat transfer tubes can be arranged in an equilateral triangle or square on the tube sheet. The equilateral triangle arrangement is more compact, the degree of fluid turbulence outside the tube is high, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning outside the tube, and is suitable for fluids that are prone to fouling.
