Product Description

Tube Heat Exchanger

Tubular Heat exchangers are also known as tube-and-tube heat exchangers. The partition wall heat exchanger is a heat transfer surface which is closed on the wall surface of the tube bundle in the casing. The heat exchanger has a simple structure and reliable operation, can be manufactured by various structural materials (mainly metal materials), can be used under high temperature and high pressure, and is the most widely used type at present.OEM replacement plate and frame heat exchanger for heating system

The shell-and-tube heat exchanger is composed of a casing, a heat transfer tube bundle, a tube sheet, a baffle (baffle), and a pipe box. The housing is mostly cylindrical, and a tube bundle is installed inside, and both ends of the tube bundle are fixed on the tube sheet. The two types of hot and cold fluids that perform heat exchange, one flowing in the tube, called the tube-flow fluid, and the other flowing outside the tube, called the shell-side fluid. In order to increase the heat transfer coefficient of the fluid outside the tube, a number of baffles are usually installed in the housing. The baffle increases the speed of the shell-side fluid, forcing the fluid to pass laterally through the tube bundle multiple times over a specified path, enhancing fluid turbulence. The heat exchange tubes can be arranged on the tube sheets in an equilateral triangle or square. The equilateral triangles are arranged in a compact manner, the fluid outside the tube is highly turbulent, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning outside the tube, and is suitable for fluids that are easy to scale.

Each time the fluid passes through the tube bundle, it is called a tube process; each time it passes through the shell, it is called a shell side. The illustration is the simplest single-shell single-tube heat exchanger, referred to as the 1-1 heat exchanger. In order to increase the fluid velocity in the pipe, spacers may be provided in the pipe boxes at both ends, and all the pipes are divided into several groups. This way the fluid passes through only a portion of the tube at a time and thus travels back and forth a plurality of times in the tube bundle, which is called multi-tube. Similarly, in order to increase the flow rate outside the tube, a longitudinal baffle can also be installed in the housing to force the fluid to pass through the housing space multiple times, which is called a multi-shell process. Multi-tube and multi-shell can be used together.water to water food grade industrial cooling Tubular Heat Exchanger

The shell-and-tube heat exchanger has different temperatures due to the temperature of the fluid inside and outside the tube, so the temperature of the shell and tube bundle of the heat exchanger is also different. If the two temperatures differ greatly, a large thermal stress will be generated in the heat exchanger, causing the tube to bend, break, or pull off the tubesheet. Therefore, when the temperature difference between the tube bundle and the casing exceeds 50 °C, appropriate compensation measures should be taken to eliminate or reduce the thermal stress. According to the compensation measures adopted, shell-and-tube heat exchangers can be divided into the following main types:

1 The tube plate at both ends of the fixed tube-plate heat exchanger tube bundle is integrated with the shell, and the structure is simple, but it is only suitable for the heat exchange operation when the temperature difference between the hot and cold fluids is not large, and the shell side does not need mechanical cleaning. When the temperature difference is slightly larger and the shell side pressure is not too high, an elastic compensation ring can be mounted on the housing to reduce thermal stress.
