Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, specifically to a low-noise heat exchange device. Background Technology

[0002] A heat exchanger is a device used to transfer heat between different media and is widely used in industries such as industry, energy, HVAC (heating, ventilation and air conditioning), chemical industry, and automotive.

[0003] The main types include shell and tube heat exchangers, plate heat exchangers, finned heat exchangers, and spiral plate heat exchangers.

[0004] When fluid (gas or liquid) flows at high speed within a heat exchanger, sudden changes in velocity or direction can generate turbulence and eddies, causing pressure fluctuations and generating noise. Direct impact of the fluid against the inner wall or pipe walls of the heat exchanger also generates noise. The noise generated during heat exchanger operation causes noise pollution in the working environment. Utility Model Content

[0005] The present invention aims to solve the problems in the prior art. Therefore, the purpose of the present invention is to provide a low-noise heat exchange device.

[0006] To achieve the above objectives, this utility model employs the following technical solution: A low-noise heat exchange device, comprising: The shell has a hollow interior and is provided with an air inlet pipe and an air outlet pipe, both of which are connected to the inner cavity of the shell. A condenser tube is disposed in a housing, with both ends of the condenser tube extending out of the housing. A noise reduction mechanism is disposed in a housing. The noise reduction mechanism includes a support frame, a first noise reduction layer, a reflective layer, and a second noise reduction layer. The support frame is disposed on the inner wall of the housing. The first noise reduction layer, the reflective layer, and the second noise reduction layer are all disposed in the support frame. The reflective layer is located between the first noise reduction layer and the second noise reduction layer, and a gap is left between the reflective layer and the first and second noise reduction layers.

[0007] Furthermore, the condenser tube is a spiral tube.

[0008] Furthermore, it also includes a water receiver, which is disposed in the housing. The water receiver includes a receiving tray, a connecting rod, a collection box, and a transmission pipe. The receiving tray is suspended in the housing and located below the condenser tube. One end of the connecting rod is connected to the housing and the other end is connected to the receiving tray. The collection box is disposed on the inner wall of the housing. One end of the transmission pipe is connected to the receiving tray and the other end is connected to the collection box.

[0009] Furthermore, the housing is provided with a detachable cover plate, which corresponds to the position of the collection box.

[0010] Furthermore, the outer walls of the shell, condenser tube, support frame, and water receiver are all provided with anti-corrosion layers.

[0011] Furthermore, the anti-corrosion layer is a polypropylene coating with a thickness of 0.5-3 mm.

[0012] Furthermore, the condenser tube has threads at both ends.

[0013] Furthermore, the shell is either a can-shaped structure or a square structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The noise generated during heat exchange in this invention is absorbed by a noise reduction mechanism, preventing noise exposure and optimizing the working environment. The noise is first absorbed and consumed by the support frame, then further absorbed and consumed by the first noise reduction layer, reducing its energy. Next, the noise is reflected by a reflective layer, with some sound waves reflected into the interior of the first noise reduction layer, where its energy is consumed again. Noise not reflected or not penetrating the reflective layer is conducted to the interior of the second noise reduction layer, where its energy is consumed once more. This multi-stage noise reduction effect is achieved.

[0015] The features and advantages of this utility model will be described in detail through embodiments in conjunction with the accompanying drawings. Attached Figure Description

[0021] like Figure 1-3As shown, a low-noise heat exchange device includes a housing 1, a condenser 2, and a noise reduction mechanism 3. The shell 1 has a hollow internal structure. An air inlet pipe 101 and an air outlet pipe 102 are provided on the shell 1. The air inlet pipe 101 is located below the shell 1, and the air outlet pipe 102 is located above the shell 1. Both the air inlet pipe 101 and the air outlet pipe 102 are connected to the inner cavity of the shell 1. A condenser pipe 2 is provided in the shell 1, and both ends of the condenser pipe 2 extend out of the shell 1. A noise reduction mechanism 3 is provided in the shell 1. The noise reduction mechanism 3 includes a support frame 301, a first noise reduction layer 302, a reflective layer 303, and a second noise reduction layer 304. The support frame 301 is provided on the inner wall of the shell 1. The support frame 301 is a frame structure. The first noise reduction layer 302, the reflective layer 303, and the second noise reduction layer 304 are all provided in the support frame 301. The reflective layer 303 is located between the first noise reduction layer 302 and the second noise reduction layer 304, and there is a gap between the reflective layer 303 and the first noise reduction layer 302 and the second noise reduction layer 304.

[0022] Based on the above technical means, the noise generated by the operation of this heat exchange equipment is first absorbed and consumed by the support frame 301, and then absorbed and consumed again by the first noise reduction layer 302 to reduce the energy of the noise. Then, the noise is reflected by the reflective layer 303, and some of the sound waves are reflected into the interior of the first noise reduction layer 302, where the energy of the noise is consumed again. The noise that is not reflected by the reflective layer 303 or penetrates the reflective layer 303 is conducted into the interior of the second noise reduction layer 304, where the energy of the noise is consumed again. Thus, multiple noise reduction effects are achieved.

[0023] Optionally, the shell 1 can be either a can-shaped structure or a square structure. Preferably, the shell 1 is a can-shaped structure. The curved surface of the can-shaped structure can evenly distribute external pressure, avoid stress concentration, and thus improve pressure and impact resistance. At the same time, the can-shaped structure has no dead corners, which facilitates fluid flow and reduces sedimentation and residue. Correspondingly, the supporting frame 301 is an annular structure, fixed to the inner wall of the shell 1, and is used to support the first noise reduction layer 302, the reflective layer 303, and the second noise reduction layer 304.

[0024] In this embodiment, both the air inlet pipe 101 and the air outlet pipe 102 are flanged connection pipes.

[0025] In this embodiment, the support frame 301 and the reflective layer 303 are both made of stainless steel plate, and the first noise reduction layer 302 and the second noise reduction layer 304 are both made of sound-insulating mineral wool.

[0026] In this embodiment, the condenser tube 2 is a spiral tube, which provides a larger surface area and increases heat exchange efficiency. Both ends of the condenser tube 2 are threaded, allowing it to connect to the condensing equipment via these threads. The upper end of the condenser tube 2 is the water inlet, and the lower end is the water outlet. Condensate flows from the upper end of the condenser tube 2 and out from the lower end, forming a circuit with the condensing equipment to provide heat exchange capacity to the interior of the casing 1.

[0027] Since hot fluids condense when cooled, the resulting droplets need to be collected. Therefore, this heat exchange equipment also includes a water collector 4, which is installed in the housing 1. The water collector 4 includes a receiving plate 402, a connecting rod 401, a collection box 404, and a transmission pipe 403. The receiving plate 402 is suspended in the housing 1 and located below the condenser tube 2. One end of the connecting rod 401 is fixed to the top of the housing 1 by welding, and the other end is fixedly connected to the receiving plate 402 by welding. The collection box 404 is welded to the inner wall of the housing 1. One end of the transmission pipe 403 is connected to the receiving plate 402, and the other end is connected to the collection box 404.

[0028] Based on the above technical means, the condensate droplets generated during the operation of this heat exchange equipment will drip into the receiving plate 402 and flow into the collection box 404 through the transmission pipe 403 at the bottom of the receiving plate 402 to be collected in a concentrated manner, which can prevent the condensate droplets from flowing into the air inlet pipe 101.

[0029] In this embodiment, a detachable cover plate 103 is provided on the housing 1. The cover plate 103 corresponds to the position of the collection box 404. Opening the cover plate 103 allows the condensate in the collection box 404 to be treated. The cover plate 103 is fixed to the housing 1 by bolts. The bolt connection allows for non-destructive disassembly, facilitating the removal of the cover plate 103. The condensate in the collection box 404 can be treated by removing the cover plate 103.

[0030] In this embodiment, the outer walls of the shell 1, condenser pipe 2, support frame 301, and water receiver 4 are all provided with anti-corrosion layers. Since this heat exchange equipment is used to treat waste gas containing chemical substances, the shell 1, condenser pipe 2, support frame 301, and water receiver 4 need to be treated with anti-corrosion measures. Preferably, the anti-corrosion layer is a polypropylene coating, and its thickness is preferably 1 mm.

[0031] This utility model relates to a low-noise heat exchange device, the working principle of which is explained in conjunction with the accompanying drawings: The gas requiring heat exchange enters the housing 1 through the inlet pipe 101. The condensate circulates in the housing 1 through the condenser pipe 2. When the gas passes through the condenser pipe 2, the heat of the gas is exchanged with the condenser pipe 2, causing the gas temperature to drop. The noise generated by the fluid flow is absorbed and consumed by the noise reduction mechanism 3. At the same time, the condensate droplets formed when the gas cools are received by the receiving plate 402 and flow along the transmission pipe 403 to the collection box 404.

[0032] All standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods that are mature in the prior art, such as bolts, rivets, welding, and adhesive bonding. The machinery, parts and equipment adopt conventional models in the prior art, which will not be described in detail here.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
