Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides an embodiment:

the utility model provides a novel shell and tube energy-efficient heat exchanger, including casing 1, casing 1's top is close to one end fixedly connected with hot-fluid entry 2, casing 1's below is close to other end fixedly connected with hot-fluid outlet 3, because casing 1's inside is the cavity of super large, hot-fluid entry 2 and hot-fluid outlet 3's pipeline and casing 1 through connection, consequently the hot-fluid flows out from hot-fluid outlet 3 after 2 entering casing 1 from one end flows to the other end through hot-fluid entry, and this process is called the shell side.

In fig. 1, the shell heads 4 are arranged on two sides of the shell 1, a groove is formed in the joint of the shell 1 and the shell head 4, a sealing ring 7 for fixedly connecting the shell 1 and the shell head 4 is arranged in the groove, the shell 1 and the shell head 4 are integrated through the connection of the sealing ring 7, so that the hot fluid inside the shell is prevented from overflowing from the junction, when the inside of the shell 1 breaks down, the shell head 4 can be detached by detaching the sealing ring 7, and then the hot fluid enters the inside of the shell 1 or parts are taken out from the inside of the shell 1 for maintenance.

In fig. 3, the two ends of the interior of the shell 1 are fixedly connected with the tube plate 8, the middle of the two tube plates 8 is provided with the drainage block 9, the tube bundle 10, the lower baffle 11 and the upper baffle 12, the drainage block 9, the lower baffle 11 and the upper baffle 12 are fixedly connected with the inner wall of the shell 1, meanwhile, the drainage block 9 is distributed at the two sides of the lower baffle 11 and the upper baffle 12 and the side of the tube plate 8 departing from the end socket 4, the tube plate 8, the drainage block 9, the lower baffle 11 and the upper baffle 12 are provided with a plurality of round through holes, the tube bundle 10 passes through the round through holes to be respectively fixedly connected with the tube plate 8, the drainage block 9, the lower baffle 11 and the upper baffle 12, and the tube bundle 10 is fixedly connected with the tube plate 8, the drainage block 9, the lower baffle 11 and the upper baffle 12 by welding or tube expansion method, because the lower part of the upper baffle 12 is provided with a circular notch, lower baffling baffle 11 is identical with last baffling baffle 12 completely, the difference is lower baffling baffle 11 is last baffling baffle 12 for invering, when the hot-fluid was in casing 1 internal motion, through baffling baffle 11 and last baffling baffle 12's accent down, make the total shell side of hot-fluid increase, thereby make the hot and cold fluidic heat exchange go on more abundant, the arc of induced flow piece 9 is modelled simultaneously, make the hot-fluid when dashing down baffling baffle 11 and last baffling baffle 12, can be guided the adjustment direction, reduce the hot-fluid and to baffling baffle 11 and last baffling baffle 12's direct striking down, greatly increased the utility model discloses an overall service life, thereby practice thrift the cost and reduce the shared time of maintenance.

Furthermore, a cavity is formed in the head 4, the cavity is generally called a distribution chamber space, the distribution chamber space is respectively communicated with the cold fluid inlet 5, the cold fluid outlet 6 and the pipeline of the tube bundle 10, when the cold fluid enters the distribution chamber space of the head 4 from the cold fluid inlet 5, the cold fluid is dispersed to enter the tube bundle 10, then flows to the distribution chamber space at one end of the cold fluid outlet 6, and finally flows out from the cold fluid outlet 6 together, and the flow of the cold fluid is generally called a tube pass.

The working principle is as follows: install this use newly at the assigned position to connect hot-fluid on hot-fluid entry 2 and communicate hot-fluid output device, hot-fluid export 3 and connect hot-fluid and connect greatly device, connect cold fluid output device on the cold fluid entry 5, connect cold fluid and connect greatly the device on the cold fluid export 6.

The during operation opens hot-fluid and cold fluid valve, makes the hot-fluid do the shell side motion in casing 1, and the cold-fluid is the tube side motion in tube bank 10, and the hot-fluid can be more in the same direction as smooth flowing through down baffling 11 and last baffling 12 behind drainage piece 9, rather than direct impact baffling 11 and last baffling 12 under on, increased the utility model discloses a life, simultaneously owing to baffling 11 and last baffling 12 have increased the shell side down, consequently cold and hot fluidic heat exchange is more abundant.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
