Disc ring type efficient heat exchanger

Abstract

A disc ring type efficient heat exchanger is provided with air chambers. The air chambers comprise the upper air chamber and the lower air chamber. Shrinkage and expansion pipes are arranged between the upper air chamber and the lower air chamber. A heat exchange chamber is arranged on the rear sides of the shrinkage and expansion pipes. A heat exchange device is arranged in the heat exchange chamber and is an annular fluid heat exchange device. An upper air distribution chamber is arranged on the lower portion of the upper air chamber. A lower air distribution chamber is arranged on the upper portion of the lower air chamber. The upper air distribution chamber is of a ring sleeve type structure. A connecting pipe plate is arranged between the lower air distribution chamber and the lower air chamber, and therefore the lower air distribution chamber and the lower air chamber can be connected more firmly, and the effect is better. A flow guide plate is arranged in the upper air distribution chamber, and therefore water flows in the heat exchanger more smoothly. A flow guide groove is formed in the lower portion of the flow guide plate, the water in the heat exchanger is collected, and therefore the situation that the water flows in the heat exchanger disorderly, and consequently normal work of the heat exchanger is influenced is avoided, the work quality of the heat exchanger is guaranteed, and the service life of the heat exchanger is prolonged.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a dish ring type high-efficiency heat exchanger. Background technique [0002] In the production of factories, heat exchangers are often used, especially hollow ring expansion tube heat exchangers. However, due to the unique structural characteristics of the shell-side deflectors of such heat exchangers, the fluid usually flows along the length of the tubes. For axial flow, the minimum limit of the center spacing of the tubes is regulated by the standard, and the diameter of the shell is also limited. The difference between the transverse sectional area of ​​the shell and the transverse sectional area of ​​several tubes is the flow area of ​​the shell side fluid , the mass flow rate of the fluid is often low and difficult to adjust, which affects the improvement of the heat transfer film coefficient of the fluid outside the tube, and some heat exchangers are often prone to water leakage at the...

[0002] In the production of factories, heat exchangers are often used, especially hollow ring expansion tube heat exchangers. However, due to the unique structural characteristics of the shell-side deflectors of such heat exchangers, the fluid usually flows along the length of the tubes. For axial flow, the minimum limit of the center spacing of the tubes is regulated by the standard, and the diameter of the shell is also limited. The difference between the transverse sectional area of ​​the shell and the transverse sectional area of ​​several tubes is the flow area of ​​the shell side fluid , the mass flow rate of the fluid is often low and difficult to adjust, which affects the improvement of the heat transfer film coefficient of the fluid outside the tube, and some heat exchangers are often prone to water leakage at the connection when they are in use, which affects the normal operation of the heat exchanger and cannot be guaranteed The normal operation of the heat exchanger makes the replacement frequency of the heat exchanger higher. With the prolongation of the service life of the equipment, the deflector on the shell side is easy to accumulate dirt and blockage, which increases the pressure drop of the fluid and affects the service life of the heat exchanger.
