Description

Technical Field

[0001] The present application relates to the field of high-temperature cooling technology, and in particular to a mechanical cooling system in a high-temperature environment. Background Art

[0002] There are many harsh working environments in industrial sites, which make it difficult for operators to operate safely on site. High temperature environment is one of the common harsh environments in industrial sites. Boilers, flues, large equipment, etc. generate a lot of heat when they work. This heat affects the surrounding working environment through heat radiation, heat convection, heat exchange, etc., making the surrounding environment a high temperature environment.

[0003] Among them, the electronic circuits, structural parts, optical components, etc. of various testing equipment (instruments) installed for testing on-site data will be affected to varying degrees or even damaged due to being in a high temperature environment for a long time, which will affect the performance and safety of the testing equipment. In severe cases, it may even cause various safety accidents, which is extremely harmful.

[0004] At present, in order to enable the detection equipment to work normally in the high temperature environment of the industrial site, two technical solutions, water cooling and air cooling, are commonly used to cool the equipment. The water cooling solution introduces cooling water to flow through the surface of the detection equipment or nearby to take away the heat; the air cooling solution introduces gas through the purge pipe to purge the detection equipment, or uses fans, air conditioners, etc. to purge the detection equipment, thereby taking away the heat accumulated by the detection equipment. However, these two technical solutions have obvious defects in use: due to the huge heat generated by the heat source at the industrial site, the surrounding area is a high temperature environment. When cooling water or purge gas is used for cooling, the cooling water or purge gas has been heated by the surrounding environment when it reaches the surface of the detection equipment, and the cooling effect on the detection equipment is not ideal, and the high-speed water flow and air flow will also affect the stability of the detection equipment; if an air conditioner is installed to cool the detection equipment, the cost is too high, and the introduction of additional electrical equipment in occasions with explosion-proof requirements will also bring safety hazards. In addition, the current technical solution mainly considers how to take away the heat of the detection equipment to achieve cooling, but does not consider reducing the heat input of the environment to the detection equipment, so the effect is not ideal. Utility Model Content

[0005] In order to overcome at least some of the defects and shortcomings in the prior art, the present application provides a mechanical cooling system in a high temperature environment, which can reduce the heat transfer of the high temperature environment to the detection equipment, reduce the temperature of the detection equipment, and ensure the normal operation of the detection equipment.

[0006] Specifically, an embodiment of the present invention provides a mechanical cooling system in a high temperature environment, which adopts the following technical solution:

[0007] A mechanical cooling system for a high temperature environment comprises: a semi-enclosed shell; a dispersed air pipe, which is located in the semi-enclosed shell and forms a cooling space around a detection device, wherein the dispersed air pipe is provided with dispersed air holes on the side facing the cooling space; and a vortex cooling pipe, one end of which is connected to the dispersed air pipe via the semi-enclosed shell, and the vortex cooling pipe is provided with a compressed air delivery port.

[0008] By adopting the above technical solution, a dispersed air duct is arranged in the semi-enclosed shell, and a cooling space for accommodating the detection equipment is formed by the dispersed air duct. Combined with the vortex cooling pipe and the compressed air delivery port, the generated cold air can flow out through the dispersed air holes of the dispersed air duct to blow cold air to the detection equipment. This can reduce the temperature of the detection equipment while reducing the heat transfer to the detection equipment from the high temperature environment, thereby ensuring the normal operation of the detection equipment.

[0009] Optionally, a mechanical cooling system in a high-temperature environment further includes: a heat insulation layer, located between the semi-enclosed shell and the dispersed air pipe, and attached to the inner side of the semi-enclosed shell.

[0010] By adopting the above technical solution, by attaching a heat insulation layer on the inner side of the semi-enclosed shell, the heat convection and heat radiation of the external environment to the detection equipment can be reduced, thereby greatly reducing the heat received by the detection equipment, ensuring that a lower temperature is maintained inside the semi-enclosed shell.

[0011] Optionally, the semi-enclosed shell includes a first shell and a second shell, and wing plates are provided on the outer sides of the first shell and the second shell, and fixing holes are provided on the wing plates, and the first shell and the second shell are fixed via the fixing holes; a notch is provided on the other side of the first shell away from the wing plate for allowing the cable of the detection device to extend therefrom.

[0012] By adopting the above technical solution, wing plates with fixing holes are provided on the first shell and the second shell, which can facilitate the disassembly and assembly of the semi-enclosed shell so that the staff can place the detection equipment and perform internal maintenance at regular intervals; by providing a notch on the first shell, the cable of the detection equipment can be extended.

[0013] Optionally, a mounting member is provided in the first shell for fixing the detection device placed in the cooling space.

[0014] By adopting the above technical solution, the installation of the mounting piece can be used to fix the detection equipment placed in the cooling space, thereby increasing the installation firmness of the detection equipment.

[0015] Optionally, the thermal insulation layer is made of aerogel material.

[0016] By adopting the above technical solution, the thermal insulation layer made of aerogel material has extremely low thermal conductivity and high flexibility. Since the air temperature near the pipeline where the detection equipment is installed is very high and the pipeline continuously emits heat radiation outward, the setting of the thermal insulation layer can greatly reduce the heat received by the equipment.

[0017] Optionally, there are a plurality of dispersion air holes, which are evenly arranged on a side of the dispersion air pipe facing the cooling space.

[0018] By adopting the above technical solution, a plurality of dispersed air holes are evenly opened on the dispersed air pipe, so that cold air can flow out evenly around the detection equipment, which can avoid mechanical interference of the concentrated outflow of cold air on the detection equipment. In addition, since the cold air flows in the dispersed air pipe and flows out from a plurality of dispersed air holes, the utilization rate of the cold air is improved, thereby improving the cooling effect.

[0019] Optionally, the semi-enclosed shell includes a front shell and a bottom plate, and the bottom plate is connected to the front shell and fixed on an external bracket.

[0020] By adopting the above technical solution, the provision of the base plate can facilitate the staff to fix the cooling system on the external bracket and facilitate the disassembly of the cooling system.

[0021] Optionally, a circular hole is formed at one end of the front shell away from the bottom plate, and a glass window is arranged on the circular hole.

[0022] By adopting the above technical solution, the setting of the glass window can prevent cold air from overflowing and will not affect the detection of the detection equipment.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By arranging a dispersed air pipe in the semi-enclosed shell, and forming a cooling space for accommodating the detection equipment by the dispersed air pipe, and then cooperating with the vortex cooling pipe and the compressed air delivery port, the generated cold air can flow out through the dispersed air holes of the dispersed air pipe to realize blowing cold air to the detection equipment, which can reduce the heat transfer of the high temperature environment to the detection equipment while reducing the temperature of the detection equipment, thereby ensuring the normal operation of the detection equipment;

[0025] 2. By attaching a heat insulation layer on the inner side of the semi-enclosed shell, the heat convection and heat radiation from the external environment to the detection equipment can be reduced, thereby greatly reducing the heat received by the detection equipment and ensuring that the temperature inside the semi-enclosed shell is maintained at a lower level;

[0026] 3. Multiple dispersed air holes are evenly opened on the dispersed air pipe so that cold air can flow out evenly around the detection equipment, which can avoid the mechanical interference of concentrated cold air flow on the detection equipment. In addition, since the cold air flows in the dispersed air pipe and flows out from multiple dispersed air holes, the utilization rate of the cold air is improved, thereby improving the cooling effect.

[0036] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be used as limitations to the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more listed items.

[0037] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0038] An embodiment of the present application discloses a mechanical cooling system in a high-temperature environment, which provides cooling for detection equipment installed on a high-temperature pipeline, such as a laser gas analyzer, and can achieve normal operation in an environment of 80°C. It is hereby explained that without the assistance of the cooling system of this embodiment, the surface temperature of the detection equipment may reach 100°C when working on-site, which will greatly reduce the performance of the detection equipment or even damage it.

[0039] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0040] See also Figure 1 A mechanical cooling system in a high-temperature environment comprises: a semi-enclosed shell 10, a dispersed air pipe 20 and a vortex cooling pipe 30. The dispersed air pipe 20 is located in the semi-enclosed shell 10 to form a cooling space around the detection equipment. The dispersed air pipe 20 is provided with dispersed air holes 21 on the side facing the cooling space to blow cold air toward the surface of the detection equipment. One end of the vortex cooling pipe 30 passes through the semi-enclosed shell 10 to connect the dispersed air pipe 20, and a compressed air delivery port 31 is provided on the vortex cooling pipe 30 to provide cold air for the dispersed air pipe 20, thereby reducing the heat transfer of the high-temperature environment to the detection equipment, reducing the temperature of the detection equipment, and ensuring the normal operation of the detection equipment.

[0041] See also Figure 2 In this embodiment, the semi-enclosed shell 10 is a left-right separated rectangular aluminum alloy, correspondingly including a first shell 11 and a second shell 12, and a wing plate 13 is provided on the first shell 11 and the second shell 12, and a fixing hole 131 is provided on the wing plate 13. The first shell 11 and the second shell 12 are bolted and disassembled through the fixing hole 131, and a circular hole 16 for connecting the detection equipment with the external pipeline is provided at one end, and a notch 111 is provided on the other side of the first shell 11 opposite to the wing plate 13, through which the cable of the detection equipment can extend.

[0042] A mounting member 112 is also provided inside the first housing 11. Figure 2 The inner top of the first shell 11 is used to fix the detection equipment placed in the cooling space, and the top of the corresponding detection equipment is also provided with a matching fixing piece. After the two are connected and fixed, the installation firmness of the detection equipment can be increased.

[0043] See also Figure 3The dispersed air pipe 20 is serpentine-shaped and surrounds the detection equipment. A plurality of dispersed air holes 21 are evenly opened toward the cooling space, that is, one side of the detection equipment. The cold air generated by the vortex cooling pipe 30 flows along the plurality of dispersed air pipes 20 and flows out from the dispersed air holes 21. This allows the cold air to flow out evenly around the detection equipment, avoiding mechanical interference to the detection equipment caused by concentrated outflow of cold air. Moreover, since the cold air flows in the dispersed air pipe 20 and flows out from the plurality of dispersed air holes 21, the utilization rate of the cold air can be improved, thereby improving the cooling effect.

[0044] See also Figure 1 In this embodiment, the vortex cooling tube 30 is installed on the semi-enclosed shell 10 as the main refrigeration device, including a compressed air delivery port 31 and an output port. The output port faces the inside of the semi-enclosed shell 10 and is used to penetrate the semi-enclosed shell 10 to connect to the dispersed air pipe 20. When compressed air is introduced into the compressed air delivery port 31, a vortex cooling effect occurs in the vortex cooling tube 30, so that the cold air with reduced temperature is delivered from the output port to the dispersed air pipe 20 and flows out from the dispersed air holes 21 to cool the detection equipment. Figure 4 , which is a schematic diagram of a detection device such as a laser gas analyzer being accommodated in a cold zone space, and the cold air flowing out of the dispersed air holes 21 can cool the laser gas analyzer.

[0045] See also Figure 5 In this embodiment, a heat insulation layer 40 is further included, which is located between the semi-enclosed shell 10 and the dispersed air pipe 20 and is attached to the inner side of the semi-enclosed shell 10 to achieve a heat insulation effect.

[0046] Among them, the insulation layer 40 uses insulation materials, such as aerogel material, which has extremely low thermal conductivity and high flexibility. Because the air temperature near the pipeline where the detection equipment is installed is very high and the pipeline continuously emits heat radiation outward, the setting of the insulation layer 40 can greatly reduce the heat received by the equipment.

[0047] See also Figure 6 and Figure 7 In another embodiment, the semi-enclosed shell 10 includes a front shell 14 and a bottom plate 15, and the bottom plate 15 is connected to the front shell 14 and fixed on an external bracket.

[0048] Among them, the base plate 15 can be assembled and fixed by bolts, which can facilitate the staff to fix the cooling system on the external bracket and facilitate the disassembly of the cooling system; it is explained here that this embodiment is different from the above embodiment only in the structure of the semi-enclosed shell 10, and the internal structure is the same.

[0049] In addition, a circular hole 16 is opened at one end of the front shell 14 away from the bottom plate 15. The setting of the circular hole 16 can facilitate the detection equipment such as laser equipment to emit a laser beam for detection, and a glass window piece 50 is arranged on the circular hole 16 to increase the sealing property of the semi-enclosed shell 10 to avoid the overflow of cold air without affecting the detection of the detection equipment.

[0050] In summary, the embodiment of the present application discloses a mechanical cooling system in a high temperature environment. By arranging a dispersed air pipe 20 in a semi-enclosed shell 10, and forming a cooling space for accommodating the detection equipment by the dispersed air pipe 20, and then cooperating with the vortex cooling pipe 30 and the compressed air delivery port 31, the generated cold air can be discharged through the dispersed air holes 21 of the dispersed air pipe 20 to realize blowing cold air to the detection equipment, which can reduce the heat transfer of the high temperature environment to the detection equipment while reducing the temperature of the detection equipment, thereby ensuring the normal operation of the detection equipment; by attaching a heat insulation layer 40 to the inner side of the semi-enclosed shell 10, the heat convection and heat radiation of the external environment to the detection equipment can be reduced, thereby greatly reducing the heat received by the detection equipment, and ensuring that a relatively low temperature is maintained inside the semi-enclosed shell; a plurality of dispersed air holes 21 are evenly opened on the dispersed air pipe 20, so that cold air flows out evenly around the detection equipment, which can avoid the concentrated outflow of cold air from causing mechanical interference to the detection equipment, and because the cold air flows in the dispersed air pipe 20 and flows out from the plurality of dispersed air holes 21, the utilization rate of the cold air is improved, thereby improving the cooling effect.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
