Description

TECHNICAL FIELD

[0001] The application relates to the technical field of heat exchangers, in particular to an adjustable air heat exchanger. BACKGROUND

[0002] The air heat exchanger is an industrial equipment for realizing heat transfer between fluids of different temperatures by using a heat transfer surface as a medium, and the working principle is based on heat conduction and convection mechanism, and the air heat exchanger is widely applied to the fields of industrial waste heat recovery, flue gas reuse of coal-fired power plants and the like. Meanwhile, according to the structure of the air heat exchanger, the air heat exchanger can be divided into two types of plate type and fin type.

[0003] The plate type air heat exchanger is a high-efficiency heat exchanger which is formed by stacking a series of metal sheets with a certain corrugated shape, and has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small land occupation, wide application and long service life. Meanwhile, according to the actual situation, the heat exchange operation of different efficiencies can be realized by increasing or reducing the internal metal sheets.

[0004] The existing application with the publication number CN119803131A discloses a multi-section plate heat exchanger, which comprises a fixed compression plate, a movable compression plate and a plurality of spacers. The plurality of spacers are arranged between the fixed compression plate and the movable compression plate, and heat exchange flow channels are formed between adjacent spacers, between the spacers and the fixed compression plate or / and between the spacers and the movable compression plate. The adjacent two heat exchange flow channels can exchange heat with each other. The plurality of heat exchange flow channels can be connected with each other and form heat exchange total channels, and the heat exchange flow channels in the same heat exchange total channel are not adjacent. All the heat exchange flow channels form at least three heat exchange total channels, and the heat exchange between at least two heat exchange total channels can be exchanged. In the above-mentioned application, the structure is compact, the land occupation is small, and the heat exchange between multiple media can be realized in the scenes of milk cooling or automobile air intake.

[0005] However, the air heat exchanger has the following defects in specific use:

[0006] 1. When the existing air heat exchanger exchanges heat with the heat medium (flue gas, etc.), a space for the movement of the cold medium (gas or liquid) needs to be arranged on the side of the metal sheet of the heat medium (flue gas, etc.) heat exchange space, and the heat medium and the cold medium move (do not contact) on the left and right sides of the metal plate to exchange heat with the heat medium (flue gas, etc.). However, when the heat exchange operation of the heat medium is performed, thermal expansion and cold contraction occur in the space for the movement of the heat medium and the cold medium, the volume of the gas in the space on the side of the metal sheet expands, and the sealing effect between the gasket and the metal sheet for sealing the heat exchange space of the metal sheet becomes poor, which easily leads to the leakage of the heat exchanged gas or liquid, and the safety is low.

[0007] 2. Existing air heat exchangers typically use gaskets to connect and assemble the multiple metal sheets involved in heat exchange with air (heat medium). However, the actual assembly of these metal sheets and gaskets is often poor, with poor gasket orientation and post-assembly stability. This can easily create gaps due to compression during gas heat exchange and liquid flow, impacting the heat exchange effect. Furthermore, large gaps exist between the metal sheets and the air heat exchanger plates during connection and assembly. This results in poor heat exchange stability and a shortened service life during long-term operation. Summary of the Invention

[0057] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person of ordinary skill in the art without creative labor should belong to the protection scope of the present application.

[0058] Embodiment one

[0059] Please refer to Figure 1 and Figure 11 An adjustable air heat exchanger comprises two side metal plate members 10, detachable assembly components 20 installed on the side of the side metal plate members 10, and a plate type air heat exchange mechanism 30 arranged between the two side metal plate members 10, wherein the plate type air heat exchange mechanism 30 comprises: a sealed heat exchange plate assembly 301 abutting against the side of the side metal plate members 10; a heat-sensitive metal plate 302 arranged on the side of the sealed heat exchange plate assembly 301; a heat exchange gasket 303 assembled on one side of the heat-sensitive metal plate 302; a cold-sensitive metal plate 304 arranged on the side of the heat-sensitive metal plate 302, one side of the cold-sensitive metal plate 304 being provided with the heat exchange gasket 303, and the two heat exchange gaskets 303 of the heat-sensitive metal plate 302 and the cold-sensitive metal plate 304 being arranged on the same side, a heat medium heat exchange space 303a being formed between the side of the heat-sensitive metal plate 302 close to the heat exchange gasket 303 and the cold-sensitive metal plate 304, wherein a refrigerant conveying space 303b is arranged on the side of the heat-sensitive metal plate 302 away from the heat medium heat exchange space 303a, the heat medium heat exchange space 303a and the refrigerant conveying space 303b are staggered, and the heat-sensitive metal plate 302, the heat exchange gasket 303 and the cold-sensitive metal plate 304 are provided with a plurality of.

[0060] In the present application, the inside of the side metal plate member 10 is respectively provided with a heat medium conduit 101 and a refrigerant conduit 102, the heat medium conduit 101 is connected with the heat medium heat exchange space 303a, and the refrigerant conduit 102 is connected with the refrigerant conveying space 303b, wherein the heat medium is conveyed from the heat medium conduit 101 on one side of one side metal plate member 10 to the heat medium conduit 101 on one side of the other side metal plate member 10, and the refrigerant is conveyed from the refrigerant conduit 102 on one side of the other side metal plate member 10 to the refrigerant conduit 102 on one side of one side metal plate member 10.

[0061] The working principle is as follows: when the heat medium (gas) is subjected to heat exchange operation, the heat medium (gas) is transported to the inside of the heat medium heat exchange space 303a through the heat medium guide pipe 101, and the refrigerant (cooling liquid or gas) is transported to the inside of the refrigerant conveying space 303b through the refrigerant guide pipe 102. At this time, the heat exchange between the refrigerant in the refrigerant conveying space 303b and the heat medium in the heat medium heat exchange space 303a is non-contact heat exchange, which maximizes the size of the heat exchange area of the heat medium and the refrigerant (non-contact), and realizes efficient heat medium (gas) heat exchange operation. Through the design of the internal structure of the heat exchange gasket 303, on the one hand, the stability of the connection and assembly of the heat exchange gasket 303 with the cold metal plate 304 and the heat metal plate 302 can be ensured, and the foolproof setting can be provided to reduce the problems of assembly misplacement or reverse of the heat exchange gasket 303. On the other hand, the connection and assembly of the heat exchange gasket 303 with the cold metal plate 304 and the heat metal plate 302 is good in sealing performance. When the heat exchange operation is performed and thermal expansion and cold contraction occur, the connection part of the heat exchange gasket 303 with the cold metal plate 304 and the heat metal plate 302 is not prone to misplacement, and the gas or liquid for heat exchange is not prone to leakage, which is high in safety.

[0062] In the present application, the sealing effect of the connection part of the side metal plate 10 with the cold metal plate 304 or the heat metal plate 302 can be effectively improved through the design of the sealing heat exchange plate assembly 301.

[0063] With reference to Figure 2 and Figure 3 , the detachable assembly component 20 comprises: a threaded assembly rod 201 penetrating through the side edges of the two side metal plate pieces 10; a threaded positioning block 202 threaded on the outside of the threaded assembly rod 201 and abutting against the side of one side metal plate piece 10; a middle positioning plate 203 mounted on the center part of the upper and lower sides of the two side metal plate pieces 10 through screws; a concave assembly frame 204 mounted on the center of the side of the side metal plate piece 10 through screws; and an I-shaped positioning frame 205 penetrating through the concave assembly frame 204 and the side metal plate piece 10, wherein the I-shaped positioning frame 205 is provided with two, and the two I-shaped positioning frames 205 abut against the bottom of the middle positioning plate 203, and the sealing heat exchange plate assembly 301, the heat metal plate 302, the heat exchange gasket 303 and the cold metal plate 304 are assembled between the two I-shaped positioning frames 205.

[0064] In the present application, one side of the I-shaped positioning frame 205 located inside the concave assembly frame 204 is clamped and fixed with an I-shaped assembly sleeve rod 2051, and the I-shaped assembly sleeve rod 2051 is installed inside the concave assembly frame 204. The outside of the I-shaped assembly sleeve rod 2051 is clamped and fixed with a concave embedding block 2052, the concave embedding block 2052 is matched with the concave assembly frame 204, and the concave embedding block 2052 is mounted on the side of the side metal plate piece 10 through screws.

[0065] In the adjustable air heat exchanger, the air heat exchanger occupies a small area during transportation, and the air heat exchanger is simple and convenient to install through the detachable air heat exchanger support structure. Meanwhile, the positions of each sealed heat exchange plate assembly 301, heat-sensitive metal plate 302, heat exchange gasket 303 and cold-sensitive metal plate 304 are vertically positioned through the installation of the I-shaped positioning frame 205 on the upper and lower sides of the sealed heat exchange plate assembly 301, heat-sensitive metal plate 302, heat exchange gasket 303 and cold-sensitive metal plate 304, so that the sealed heat exchange plate assembly 301, heat-sensitive metal plate 302, heat exchange gasket 303 and cold-sensitive metal plate 304 are ensured to be on the same horizontal plane after installation. Moreover, the I-shaped positioning frame 205 for installing the sealed heat exchange plate assembly 301, heat-sensitive metal plate 302, heat exchange gasket 303 and cold-sensitive metal plate 304 is installed outside the side metal plate 10 through the I-shaped assembly rod 2051 and the concave embedded block 2052 installed at both ends of the I-shaped positioning frame 205, so that the relative stability of the position of the I-shaped positioning frame 205 is ensured after installation, and the state of the heat exchanger during work is improved.

[0066] With reference to the drawings Figure 5 The sealed heat exchange plate assembly 301 comprises a sealed rubber gasket 3011 abutting against both sides of the side metal plate 10, and a side pressure metal plate 3012 clamping and fixing the sealed rubber gasket 3011, the side of the side pressure metal plate 3012 abutting against the heat-sensitive metal plate 302 through the heat exchange gasket 303, wherein the inside corner of the side pressure metal plate 3012 is provided with a flow-through hole 30121 for the flow of heat medium and cold medium.

[0067] In the present application, the heat-sensitive metal plate 302 and the cold-sensitive metal plate 304 have the same structure and shape, the lower part of the inside corner of the heat-sensitive metal plate 302 and the cold-sensitive metal plate 304 and the part flowing through the heat medium is provided with a lower inclined flow-through channel 3021 installed on the side of the heat-sensitive metal plate 302, the lower part of the lower inclined flow-through channel 3021 is provided with a V-shaped heat exchange convex plate 3022, a plurality of V-shaped heat exchange convex plates 3022 are provided, and gaps are left between the plurality of V-shaped heat exchange convex plates 3022, wherein the lower inclined flow-through channel 3021 and the V-shaped heat exchange convex plate 3022 are both arranged on one side inside the heat exchange gasket 303, and the edge part of the V-shaped heat exchange convex plate 3022 abuts against the inner wall of the heat exchange gasket 303.

[0068] In the adjustable air heat exchanger, the sealing rubber gasket 3011 is designed to ensure the sealing performance of the side pressure metal plate 3012 when assembled with the heat-sensing metal plate 302 (or the cold-sensing metal plate 304) and the side metal plate 10, thereby reducing the probability of gas or liquid leakage during the heat exchange of the gas. The lower inclined flow guide channel 3021 is designed to ensure that the heat medium moves to one side of the V-shaped heat exchange tab 3022, and the corrugated structure of the V-shaped heat exchange tab 3022 effectively increases the heat exchange surface area. Moreover, the V-shaped heat exchange tab 3022 is tapered, which can increase the heat transfer surface area of the heat exchanger by several times or even dozens of times, thereby improving the heat transfer efficiency.

[0069] With reference to Figure 9 and Figure 10 The heat-sensing metal plate 302 and the cold-sensing metal plate 304 are provided with an embedded groove 3041 at the edge of the inner part, which is matched with the structure of the heat exchange gasket 303. The side of the embedded groove 3041 is provided with a plurality of mountain-shaped embedded grooves 3042. The embedded groove 3041 is arranged outside the lower inclined flow guide channel 3021 and the V-shaped heat exchange tab 3022.

[0070] In the adjustable air heat exchanger, the embedded groove 3041 and the mountain-shaped embedded groove 3042 are designed to ensure that the heat-sensing metal plate 302 and the cold-sensing metal plate 304 are not easily displaced due to the impact of gas or liquid when the heat exchange gasket 303 is only assembled and positioned. The mountain-shaped embedded grooves 3042 arranged at different positions have a foolproof structure, which can reduce the risk of the heat exchange gasket 303 being installed upside down and improve the efficiency of assembling the air heat exchanger.

[0071] With reference to Figure 9 The media channel 3031 is arranged at the inner corner of the heat exchange gasket 303, and the media channel 3031 is connected with the heat medium and cold medium conveying channels arranged at the inner corner of the heat-sensing metal plate 302 and the cold-sensing metal plate 304. A plurality of mountain-shaped embedded bodies 3032 are equidistantly arranged outside the heat exchange gasket 303, and the mountain-shaped embedded bodies 3032 are matched with the mountain-shaped embedded grooves 3042.

[0072] With reference to Figure 10 and Figure 11The inner corner of the heat exchange gasket 303 is provided with an O-shaped ring 3033, the inner part of the O-shaped ring 3033 is provided with a medium channel 3031, the O-shaped ring 3033 is provided with two, and the two O-shaped rings 3033 are provided on the same side, wherein the side surface of the O-shaped ring 3033 is provided with a bent sealing piece 3034 mounted at the inner corner of the heat exchange gasket 303, and the eccentric part of the side surface of the bent sealing piece 3034 is provided with a middle connecting piece 3035 connected with the O-shaped ring 3033.

[0073] In the adjustable air heat exchanger, through the design of the O-shaped ring 3033 and the bent sealing piece 3034 structure, the heat medium or the refrigerant actively transported in the medium channel 3031 can be segmented, on the one hand, to ensure that the heat medium and the refrigerant are respectively moved to the two sides of the heat-sensitive metal plate 302 or the cold-sensitive metal plate 304, and the heat exchange operation is facilitated by non-contact. On the other hand, the structure design of the two sealing structures can reduce the probability of the heat medium entering the misaligned heat exchange space. The obliquely arranged middle connecting piece 3035 can support the positions of the O-shaped ring 3033 and the bent sealing piece 3034, ensure the stability of the O-shaped ring 3033 and the bent sealing piece 3034 when they are extruded by gas or liquid, and reduce the probability of leakage caused by deformation, thereby improving the sealing performance during heat exchange.

[0074] Embodiment two

[0075] In use, when the heat exchange gasket 303 is used as a sealing element, the heat medium and the refrigerant transported into the air heat exchanger are respectively transported and heat exchanged (on the left and right sides of the heat-sensitive metal plate 302 and the cold-sensitive metal plate 304), and as the O-shaped ring 3033 of the heat exchange gasket 303 is continuously used and the heat medium damages the O-shaped ring 3033, the O-shaped ring 3033 is prone to gaps (causing leakage of the heat medium or the refrigerant). When the O-shaped ring 3033 leaks (gas) due to slight damage, it is difficult for the staff to directly and simply find that the O-shaped ring 3033 is damaged, and generally only when the gap of the damaged O-shaped ring 3033 expands to a certain length can it be found. At this time, a large amount of gas will leak in the process, and the safety is low.

[0076] Therefore, with reference to Figure 11 and Figure 12 , a plurality of pressure relief channels 40 are arranged on the side of the heat exchange gasket 303 close to the O-shaped ring 3033 and near the bent sealing piece 3034, and the pressure relief channels 40 are connected with the gas valve, wherein a roof protrusion 401 is arranged on the top of the heat exchange gasket 303, and the top of the roof protrusion 401 is arranged in a parallel state.

[0077] In the adjustable air heat exchanger, when the O-shaped ring 3033 is damaged due to long-term use (a gap and a through hole for gas leakage are generated), the leaked gas can be circularly guided and transmitted to the gas valve and the detection module for real-time monitoring, so that the damaged O-shaped ring 3033 can be repaired in time, and the damaged part of the O-shaped ring 3033 can be known clearly. The structure of the top roof protrusion 401 of the heat exchange gasket 303 ensures that the heat exchange gasket 303 can be fully embedded into the two sides of the groove 3041 to expand and fill through the extrusion force generated during assembly, and compared with the traditional abutting and clamping assembly, the probability of gas or fluid (heat medium or coolant) leakage can be further reduced, and the safety is high.

[0078] Embodiment three

[0079] The heat exchanger of the present application is not limited to high-temperature gases such as flue gas as the heat exchange medium, but is also applicable to liquid heat exchange medium. At the same time, as the heat exchange medium, it is not limited to low-temperature gases such as cooling gas, but is also applicable to common low-temperature coolants such as water.

[0080] The sealing rubber gasket 3011 in the present application is also provided with the structure of the O-shaped ring 3033, the bent sealing plate 3034 and the intermediate connecting plate 3035 at the inside corner, and the roof protrusion 401 is also arranged at the top of the sealing rubber gasket 3011; the mountain-shaped embedded body 3032 is also arranged at the outside of the sealing rubber gasket 3011, and the mountain-shaped embedded body 3032 is installed on the side of the side pressing metal plate 3012. The difference lies in that the O-shaped ring 3033, the bent sealing plate 3034 and the intermediate connecting plate 3035 are all provided with four.

[0081] Therefore, any person skilled in the art can make equivalent replacements or changes to the technical solutions and the inventive concept of the present application within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application.
