Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an internal leakage-proof heat exchanger. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. Its main function is to transfer part of the heat of the hot fluid to the cold fluid to meet process conditions and improve energy utilization.

[0003] During heat exchanger operation, solid particles in the cooling and heating media (such as fine dust, insoluble salts, and sediment) accumulate on the heat exchanger tubes, forming scale. This scale not only reduces heat exchange efficiency but can also cause corrosion and perforation of the tubes or surfaces, leading to internal leakage. This not only reduces heat exchange efficiency between the cooling and heating media, affecting the overall performance of the heat exchanger, but also poses a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an anti-internal leakage heat exchanger.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] In addition, a preferred structure is that the outer side of the fixing ring is provided with an external thread, and the cold inlet pipe and the hot inlet pipe are provided with thread grooves corresponding to the external thread.

[0008] In addition, a preferred structure is that the diameter of the thread groove is larger than the diameter of the inner tube wall of the cold inlet pipe and the hot inlet pipe, and an installation cavity is opened on the inner tube wall of the cold inlet pipe and the hot inlet pipe on the inner side of the thread groove.

[0009] In addition, a preferred structure is that an annular cavity is opened on the inner tube wall of the cold inlet pipe and the hot inlet pipe, and the annular cavity passes through the installation cavity.

[0010] In addition, a preferred structure is that a reinforcement ring is fixedly provided on the bottom of the fixing ring, and the reinforcement ring is adapted to the ring cavity.

[0011] In addition, a preferred structure is that a filter screen is provided in the middle of the filter assembly, a mounting piece is fixedly provided on the outside of the filter assembly, and a reinforcement cavity is adapted to be opened at the top of the mounting piece corresponding to the reinforcement ring.

[0012] The beneficial effect of the utility model is that, by setting the fixing ring, the filter assembly can be fixedly installed in the cold inlet pipe and the hot inlet pipe, so that the solid particles in the cold medium and the hot medium entering the heat exchanger assembly can be filtered and intercepted through the filter mesh on the filter assembly, so as to prevent the solid particles from scaling and corroding the heat exchange pipe, thereby preventing the heat exchanger body from internal leakage.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-6A heat exchanger with internal leakage prevention includes a heat exchanger body 1, which is provided with a cold inlet pipe 11 and a hot inlet pipe 12. Each of the cold inlet pipe 11 and the hot inlet pipe 12 has a detachable filter assembly 3 installed therein, and the filter assembly 3 is secured by a retaining ring 4. A plurality of mounting members 32 are provided on the outside of the filter assembly 3. Mounting cavities 21 corresponding to the mounting members 32 are formed on the inner walls of the cold inlet pipe 11 and the hot inlet pipe 12, and the retaining ring 4 is assembled on the outside of the filter assembly 3.

[0022] The heat exchanger body 1 is also equipped with a cold outlet pipe and a hot outlet pipe. The principle of the heat exchanger is based on heat transfer, that is, heat is transferred from one fluid to another through various means to achieve the purpose of regulating the temperature of the two fluids. The cold medium enters through the cold inlet pipe 11 and flows out of the cold outlet pipe. The hot medium enters through the hot inlet pipe 12 and flows out of the hot outlet pipe, thus achieving heat exchange between the hot and cold media. This is prior art, so it will not be described in detail.

[0023] The outer side of the fixing ring 4 is provided with an external thread 42, and the cold inlet pipe 11 and the hot inlet pipe 12 are both provided with a thread groove 2 corresponding to the external thread 42. The fixing ring 4 can be installed by the threaded connection between the external thread 42 and the thread groove 2.

[0024] The diameter of the thread groove 2 is larger than the diameter of the inner wall of the cold inlet pipe 11 and the hot inlet pipe 12, and a mounting cavity 21 is formed on the inner wall of each of the cold inlet pipe 11 and the hot inlet pipe 12, located inside the thread groove 2. The filter assembly 3 can be fixedly installed by the adapter between the mounting cavity 21 and the mounting member 32.

[0025] The inner walls of the cold inlet pipe 11 and the hot inlet pipe 12 are both provided with an annular cavity 22, and the annular cavity 22 passes through the mounting cavity 21. A reinforcement ring 41 is fixedly provided at the bottom of the fixing ring 4, and the reinforcement ring 41 is adapted to the annular cavity 22.

[0026] A filter screen 31 is provided in the middle of the filter assembly 3, and a mounting member 32 is fixedly provided on the outside of the filter assembly 3. A reinforcement cavity 321 is provided at the top of the mounting member 32, corresponding to the reinforcement ring 41. When the filter assembly 3 is installed in the cold inlet pipe 11 or the hot inlet pipe 12, the mounting member 32 fits within the installation cavity 21, and the reinforcement cavity 321 on the mounting member 32 is aligned with the ring cavity 22.

[0027] In this embodiment, before the user assembles and uses the device, the filter assembly 3 can be installed in the cold inlet pipe 11 and the hot inlet pipe 12 on the heat exchanger assembly 1, so that the solid particles in the cold medium and the hot medium entering the heat exchanger assembly 1 can be filtered through the filter mesh 31 on the filter assembly 3 to prevent the solid particles from scaling on the heat exchange pipe, thereby preventing the inner pipe of the heat exchanger assembly 1 from being corroded due to scaling and leaking.

[0028] Furthermore, when the user needs to install the filter assembly 3, he only needs to insert the mounting piece 32 on the outside of the filter assembly 3 into the mounting cavity 21 inside the cold inlet pipe 11 and the hot inlet pipe 12. At this time, the reinforcement cavity 321 on the mounting piece 32 is aligned with the annular cavity 22 on the mounting cavity 21. The user can then install the fixing ring 4 on the outside of the filter assembly 3 through the threaded connection between the external thread 42 and the thread groove 2. During the installation of the fixing ring 4, the reinforcement ring 41 gradually enters the annular cavity 22 and the reinforcement cavity 321, so that the fixed installation of the filter assembly 3 can be achieved through the setting of the fixing ring 4 and the reinforcement ring 41. This installation method is quick and convenient, and it is convenient for the user to disassemble and clean the filter assembly 3 later.

[0029] In the present invention, by setting the fixing ring 4, the filter assembly 3 can be fixedly installed in the cold inlet pipe 11 and the hot inlet pipe 12, so that the solid particles in the cold medium and the hot medium entering the heat exchanger assembly 1 can be filtered and intercepted through the filter mesh 31 on the filter assembly 3, so as to prevent the solid particles from scaling and corroding the heat exchange pipe, thereby preventing the heat exchanger body 1 from internal leakage.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
