It is distributed due to using this arc, when liquid spray thrower of the invention is installed in shell-and-tube phase change heat exchanger
When, as shown in Fig. 2, the liquid spray thrower is distributed along the shell of shell-and-tube phase change heat exchanger, to save space, increase
The heat exchanger tube filling rate of the number of heat exchange tubes that the heat exchanger can accommodate, heat exchanger significantly improves.Shell-and-tube phase change heat exchanger system
Cause this significant decrease.
Detailed description of the invention
Fig. 1 is the perspective view of fluid present invention spray thrower.
Fig. 2 is the cross-sectional view for being equipped with the shell-and-tube heat exchanger of fluid present invention spray thrower.
Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with attached drawing, to be clearer to understand mesh of the invention
, features and advantages.It should be understood that embodiment shown in the drawings does not limit the scope of the present invention, and it is intended merely to
Illustrate the connotation of technical solution of the present invention.
Fig. 1 shows the liquid spray thrower 10 for shell-and-tube phase change heat exchanger of an embodiment according to the present invention.Fig. 2 shows
The cross-sectional view of the shell-and-tube heat exchanger of fluid present invention spray thrower 10 is installed out.As illustrated in fig. 1 and 2, shell-and-tube phase inversion
Hot device 20 includes shell 21 and heat exchanger tube 22, is equipped with liquid spray thrower 10 on the inside of shell 21, liquid spray thrower 10 is placed in heat exchange
22 top of pipe.
Liquid spray thrower 10 includes: inlet tube 1, collecting pipe 2, more medium pipelines 3 and more on medium pipeline 3
A spray head 4.Inlet tube 1, collecting pipe 2 and medium pipeline 3 are in fluid communication with each other, thus heat transferring medium can by inlet tube 1 into
Enter collecting pipe 2, and enter medium pipeline 3 via collecting pipe, finally oozes or spray from multiple spray heads 4 on medium pipeline 3.
Collecting pipe and more medium pipelines are arranged in and match with the inner wall shape of shell-and-tube heat exchanger 20, such as Fig. 2 institute
Show, so that shell-and-tube heat exchanger 20 can accommodate more heat exchanger tubes 21.Specifically, in the embodiment shown in Figure 2, shell-and-tube
The housing section of heat exchanger 20 is substantially circular in shape, and correspondingly, collecting pipe 2 is arc-shaped, and medium pipeline 3 also arranges camber,
So that liquid spray thrower 10 is bonded the inner surface of shell-and-tube heat exchanger 20 as far as possible, space is saved.
Specifically, in embodiment shown in Fig. 2, inlet tube 1 is a tee tube.There are three interconnected pipes for its band
Mouthful, two of them nozzle is connect with collecting pipe 2, another nozzle and heat transferring medium fluid communication.One as the present embodiment
Kind deformation, inlet tube 1 or two siphunculus, one nozzle and collecting pipe 2 are in fluid communication, another nozzle and heat transferring medium
Fluid communication.The inlet tube of other forms can also be applied, and no longer be described in detail one by one as space is limited herein.
Collecting pipe 2 is the pipe of an arc-shaped bend, and cross section is quadrangle, and two sides connect multiple medium pipelines 3, thus
The collecting pipe 2 and medium pipeline 3 are in fluid communication.The collecting pipe of other forms, such as cross section are circle, as long as the collecting pipe is in
Arc-shaped bend is readily applicable to the present invention.
Preferably, collecting pipe 2 and medium pipeline 3 can be by carbon steel, low-alloy steel, stainless steel, copper, corronil, aluminium

Medium pipeline 3 is made of more elongated tubulars.These pipe one end are connected to 2 side of collecting pipe, one end sealing.The medium
Multiple spray heads 4 are connected on the tube wall of pipeline 3, medium pipeline 3 and spray head 4 are in fluid communication, so that heat transferring medium can be from spray head 4
It sprays or oozes.
Heat transferring medium is entered by inlet tube 1 flows to each medium pipeline 3 through collecting pipe 2, then from the spray on each medium pipeline 3
Head flows out the liquid spray thrower.
Heat transferring medium can be any of suitable medium in this field, such as common phase-change heat-exchange material water or
Oil is also possible to inorganic PCM, organic PCM and compound PCM.Wherein, inorganic PCM mainly has crystalline hydrate salt, fuse salt
Class, metal or alloy class etc.；Organic PCM mainly includes paraffin, acetic acid and other organic matters.
Since collecting pipe 2 is convexly curved, causes and the medium pipeline of the return pipe 2 fluid communication is on the whole also in arc
Shape arrangement.To which entire liquid spray thrower is an arcuate structure.
It is distributed due to using this arc, when liquid spray thrower of the invention is installed in shell-and-tube phase change heat exchanger
When, which is distributed along the shell of shell-and-tube phase change heat exchanger, to save space, increasing the heat exchanger can
With the number of heat exchange tubes of receiving, the heat exchanger tube filling rate of heat exchanger is significantly improved.
As shown in Fig. 2, after being mounted with liquid spray thrower of the invention, the shell-and-tube phase change heat exchanger of unit volume can be with
More heat exchanger tubes are filled, the heat exchanger tube filling rate of heat exchanger significantly improves, and compares existing shell-and-tube phase change heat exchanger, filling
Rate improves 25-55%.Simultaneously as the quantity of heat exchanger tube increases, and heat exchange efficiency improves as a result, phase under conditions of same volume
Than in existing shell-and-tube heat exchanger, heat exchange efficiency improves 15-25%.
The embodiments of the present invention are described in detail for above-mentioned combination attached drawing, but the present invention is not limited to above-mentioned implementations
Mode.Even if should be understood that various changes can be made to the present invention, as long as the technical personnel in the technical field do not need creativeness
