Tubular heat exchange device

Abstract

The invention relates to the technical field of liquid heating, and discloses a double-tube heat exchange device which is movably sleeved with a heat conduction device through an adjusting plate and comprises a base, supporting frames are fixedly installed at the positions, close to the two ends, of the top of the base, a shell is fixedly installed at the tops of the supporting frames, and a telescopic power machine is fixedly installed at one end of the outer surface of the shell. An adjusting device is fixedly mounted at one end of an output shaft of the telescopic power machine, penetrates through the shell and extends into the shell, and a limiting sleeve is fixedly mounted at one end of the inner wall of the shell, so that liquid entering from a liquid guide flange opening cannot enter a containing cavity in the left side of the sealing plate under the common sealing effect of the sealing plate and an adjusting plate; therefore, the bending positions of the heat exchange tubes cannot be in contact with the liquid, and the problem that the temperature of the finally flowing-out liquid deviates due to uneven heat conduction caused by different total contact areas of the heat exchange tubes at different positions in the shell and the liquid due to different bending radiuses is solved.

Description

technical field [0001] The invention relates to the technical field of liquid heating, in particular to a tubular heat exchange device. Background technique [0002] Heat exchanger is a very common heating equipment, which is often used in various industries such as chemical industry, medicine, smelting, etc. It uses high-temperature or low-temperature liquid medium to heat or cool the target liquid. The basic structure of the existing heat exchange device is as follows: The cavity, the heat pipe and the connecting flange are formed. The target liquid is passed into the heat pipe through the flange, and then the medium liquid is passed into the cavity, and the heat exchange occurs through the contact between the heat pipe and the medium liquid. In this way, the heating and cooling of the target liquid can be realized, which is also the most widely used heat exchange device at present, and has the advantages of simple structure, low price, and convenient use.

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing tubular heat exchange device proposed in the background technology, the present invention provides a tubular heat exchange device, which has the advantage of convenient temperature adjustment of the target liquid and solves the problem of traditional equipment. Constant volume cavity leads to more complex temperature adjustment
