[0049] The present application provides a heat exchanger, combined with Figure 1 and Figure 2 The heat exchanger 100 includes a shell 110, a heat exchange component 120 and a support component 130, wherein the heat exchange component 120 and the support component 130 are arranged in the shell 110, and a accommodating space 111 is formed inside the shell 110, and the accommodating space 111 is used to accommodate the heat exchange component 120 and the support component 130. The support component 130 supports the heat exchange component 120 in the accommodating space 111 of the shell 110, so that the heat exchange component 120 has sufficient heat exchange space, wherein the heat exchange component 120 includes a plurality of heat exchange tubes 121, and the plurality of heat exchange tubes 121 are arranged at intervals in the accommodating space 111 of the shell 110, and the support component 130 is respectively connected to the plurality of heat exchange tubes 121 to support the plurality of heat exchange tubes 121.

[0050] Combination Figure 3 In one embodiment of the present application, the shell 110 of the heat exchanger 100 includes a frame 115 and a plurality of enclosures 116 , and the plurality of enclosures 116 and the frame 115 together enclose a shell 110 having a receiving space 111 .

[0051] In another embodiment, a partial support assembly 130 disposed near the welding side 112 and a plurality of enclosures 116 together enclose a receiving space 111, and the partial support assembly 130 and the plurality of enclosures 116 serve as wall panels of the shell, wherein the support assembly 130 includes a support member 131, and the support member 131 on the welding side 112 of the frame 115 serves as a side wall of the shell 110.

[0052] The support member 131 can also be configured as a structure in which a support plate 132 and an outer end plate 133 are connected. The outer surface of the outer end plate 133 and the outer surface of each enclosure can be provided with an anti-rust layer to resist erosion of the heat exchanger shell by gas or liquid in the external environment.

[0053] Combination Figure 7 A welding side 112 is provided on one side of the frame 115 of the heat exchanger 100. The welding side 112 is used for welding part of the heat exchange component 120 and for installing the heat exchange component 120, the support component 130, and other related components in the shell 110. A plurality of connection positions 113 are also provided on the frame 115. The frame 115 is connected to the support component 130 through the plurality of connection positions 113. The support component 130 is respectively connected to the frame 115 and the heat exchange component 120, and supports the heat exchange component 120 in the shell 110. At least part of the connection positions 113 are provided near the welding side 112 of the frame 115, and the heat exchange component 120 is extended from the welding side 112 to the accommodating space 111 of the shell 110. The support assembly 130 is arranged in sequence inside, and when it is connected to different connection positions 113 near the welding side 112 of the frame 115, it can be connected to the connection position 113 located on the welding side 112 of the frame 115 to support the heat exchange assembly 120 on the welding side 112, and can also be connected to the connection position 113 of the frame 115 away from the welding side 112, so that the shell 110 and the frame 115 have a larger operating space near the welding side 112. When the heat exchange assembly 120 on the welding side 112 is welded, since the support assembly 130 is connected to the frame 115 at the connection position 113 away from the welding side 112, the damage to the support assembly 130 caused by flames and high temperature during the welding process can be reduced.

[0054] Among them, multiple connection positions on the frame can be continuously arranged to form a guide rail, which is arranged to intersect with the welding side of the frame, and the guide rail extends from the welding side to a direction away from the welding side. Therefore, when a sliding part that cooperates with the guide rail is provided on the support component, the sliding part of the support component can move along the guide rail in a direction away from the welding side, so that the part of the support component arranged close to the welding side is away from the welding side by a certain distance, so as to reduce the damage to the support component caused by the welding flame.

[0055] Among them, at least one connection position is set along the height direction of the welding side, and some support components set close to the welding side can be movably connected to the connection position. When the support components are connected to multiple connection positions along the height direction, the support group can be connected to the frame more firmly.

[0056] It needs to be explained that the heat exchange component 120 in the heat exchanger 100 includes a plurality of heat exchange tubes 121, which have a relatively large weight and require a support component 130 to support the plurality of heat exchange tubes 121. In particular, when welding part of the heat exchange component 120 on the welding side 112 of the frame 115, it is necessary to support the plurality of heat exchange tubes 121 in the heat exchange component 120 before welding. After welding, the positions of the plurality of heat exchange tubes 121 in the heat exchange component 120 are relatively fixed. The support component 130 needs to ensure that the relative positions of the plurality of heat exchange tubes 121 in the heat exchange component 120 are fixed to avoid cracking of the welding joints 123 of the heat exchange tubes 121 in the heat exchange component 120 under the influence of gravity.

[0057] Therefore, in the heat exchanger of the present application, multiple welding ports 123 in the heat exchange component 120 are set on the welding side 112 of the frame 115, and the welding work of the multiple welding ports 123 of the heat exchange component 120 is completed on the welding side 112. The welding side 112 of the frame 115 has a larger operating space, which can ensure that the multiple heat exchange tubes 121 of the heat exchange component 120 are welded in different directions. The support component 130 can also support the multiple heat exchange tubes 121 of the heat exchange component 120 during the welding process, ensuring that the multiple heat exchange tubes 121 have a relatively fixed positional relationship.

[0058] The heat exchanger 100 of the present application has a partial heat exchange component 120 disposed on the welding side 112 close to the frame 115, which is movably connected to a plurality of connection positions 113 on the frame 115, so that the support component 130 can support the heat exchange component 120 at different positions according to the welding process, and the relative distance between the support component 130 and the welding position can be adjusted during the welding process to reduce high-temperature burns to the support component 130 caused by the welding flame.

[0059] The heat exchanger in this embodiment has a welding side 112 on at least one side of the frame 115, a heat exchange component 120 is provided in the frame 115, the heat exchange component 120 has multiple welding ports and is located on the welding side 112, and the frame 115 has multiple connection positions 113, which are arranged in sequence on one side of the frame 115 in a direction away from the welding side 112; the support component 130 is respectively connected to the frame 115 and the heat exchange component 120, and a part of the support component 130 arranged close to the welding side 112 can be movably connected to the multiple connection positions 113.

[0060] Combination Figure 3 and Figure 4In one embodiment of the present application, the heat exchange assembly 120 of the heat exchanger 100 includes a plurality of heat exchange tubes 121, and the plurality of heat exchange tubes 121 are connected to a support assembly 130. The plurality of heat exchange tubes 121 are welded through a plurality of welding ports 123, wherein the plurality of welding ports 123 in the welding assembly are arranged on the plurality of heat exchange tubes 121. In the present embodiment, the welding between the plurality of heat exchange tubes 121 is completed on the welding side 112 of the frame 115. During the welding process, the support assembly 130 supports the plurality of heat exchange tubes 121.

[0061] Before welding a plurality of heat exchange tubes, the position of the welding joints 123 between the support assembly 130 and the plurality of heat exchange tubes 121 should be adjusted. The support assembly 130 is connected to a connection position 113 on the inner frame 115 of the shell 110 away from the welding side 112 to reduce the influence of the high temperature of welding on the support assembly 130. The specific adjustment position can be determined according to the welding process, by determining the length of the welding flame and adjusting the relative distance between the support assembly 130 and the welding joints 123 of the heat exchange tubes 121.

[0062] Among them, in order to better support the multiple heat exchange tubes 121, the support assembly 130 includes a support plate 132, and a plurality of through holes are arranged on the support plate 132. The multiple heat exchange tubes 121 are inserted into the multiple through holes, so that the support plate 132 can well support the multiple heat exchange tubes 121 and ensure the relative position relationship between the multiple heat exchange tubes 121.

[0063] In order to facilitate the adjustment of the distance between the support assembly 130 and the welding joints 123 of the multiple heat exchange tubes 121, the multiple connection positions 113 on the frame 115 can be set as slide rails, and the support assembly 130 is slidably connected to the slide rails. The support assembly 130 slides on the slide rails to adjust the relative distance between the welding joints 123 of the heat exchange tubes 121.

[0064] In one embodiment of the present application, the heat exchange assembly 120 further includes a header 122, the header 122 has a plurality of welding ports 123, the header 122 is welded to the plurality of heat exchange tubes 121 through the welding ports 123, the header 122 is arranged on the welding side 112 of the frame 115, the heat exchanger 100 in this embodiment is provided with at least one header 122, the header 122 can be provided as a liquid collector, and can also be provided as a gas collector, a refrigerant is provided in the liquid collector and the gas collector, the liquid collector is used to collect and distribute the liquid refrigerant in the heat exchange tube 121, the gas collector is used to collect and distribute the gaseous refrigerant in the heat exchange tube 121, and the refrigerant is collected. The rear manifold 122 has a large weight, and the support assembly 130 is required to support the vicinity of the welding position where the manifold 122 is connected to the heat exchange tube 121 to avoid warping and deformation between the manifold 122 and the heat exchange tube 121, or even cracking of the welding joint 123. During the welding process of the manifold 122 and the heat exchange tube 121, the support assembly 130 should be as far away from the welding joint 123 between the heat exchange tube 121 and the manifold 122 as possible while supporting the heat exchange tube 121. The support assembly 130 is connected to the connection position 113 on the frame 115 away from the welding side 112 to reduce the impact of the welding high temperature and the welding flame on the support assembly 130.

[0065] Among them, combined Figure 5 and Figure 6 The support assembly 130 includes a support plate 132, and a plurality of first through holes 1321 are provided on the support plate 132. The plurality of heat exchange tubes 121 pass through the plurality of first through holes 1321 and extend out of one side of the support plate 132, and are welded to the header 122 in the welding side 112 area of ​​the frame 115. In the heat exchanger 100 of this embodiment, the plurality of heat exchange tubes 121 pass through the first through holes 1321 and extend out of one side of the support plate 132. The support plate 132 supports the plurality of heat exchange tubes 121. The tubes 121 can all form good support. After the multiple heat exchange tubes 121 are welded to the collecting tube 122, the support plate 132 can support both the heat exchange tubes 121 and the collecting tube 122. Even if the collecting tube 122 has a large weight, the support plate 132 provides stable support for the heat exchange tubes 121 and the collecting tube 122, and can still ensure that the welding joint 123 between the heat exchange tube 121 and the collecting tube 122 is subjected to a smaller bending moment to avoid cracking of the welding joint 123.

[0066] The benefit of setting the support plate 132 in the heat exchanger 100 in this embodiment is that a plurality of first through holes 1321 are set on the support plate 132, which can support the plurality of heat exchange tubes 121 in the heat exchange assembly 120, wherein the plurality of heat exchange tubes 121 can be arranged in multiple layers, and each layer of heat exchange tubes 121 includes a plurality of heat exchange tubes 121 arranged in parallel, thereby improving the heat exchange efficiency of the heat exchanger 100. A plurality of liquid collecting pipes can also be arranged on one side of the support plate 132, each liquid collecting pipe is welded to the plurality of heat exchange tubes 121, and the support plate 132 can support the plurality of heat exchange tubes 121 and the plurality of liquid collecting pipes.

[0067] In one embodiment of the present application, the diameter of the manifold 122 is larger than the diameter of the heat exchange tube 121. Since the diameter of the manifold 122 is larger than the diameter of the heat exchange tube 121 and it is welded with multiple heat exchange tubes 121, especially when the diameter of the manifold 122 is larger, its weight is heavier. Multiple welding positions connecting the manifold 122 and the heat exchange tube 121 cannot withstand excessive bending moments. Therefore, a support assembly 130 is required to support the manifold 122 and the heat exchange tube 121, and the relative positions between the manifold 122 and the multiple heat exchange tubes 121 and the relative positions between the multiple heat exchange tubes 121 are fixed before welding to avoid large movements of the manifold 122 and the heat exchange tube 121 during welding, causing misalignment of the welding joint 123, and to avoid large movements of the manifold 122 and the heat exchange tube 121 after welding, causing cracking of the welding joint 123.

[0068] It should be noted that, under the condition that the diameter of the manifold 122 is larger than the diameter of the heat exchange tube 121, it is not suitable for the heat exchange tube 121 to extend a long distance out of the shell 110 and the support assembly 130. After welding with the manifold 122, the heat exchange tube 121 and the manifold 122 are moved into the shell 110. The heavier manifold 122 and heat exchange tube 121 are not suitable for overall movement after welding, and the connection at the welding position is weak and easy to crack. Therefore, it is necessary to limit the relative position between the heat exchange tube 121 and the manifold 122 in the heat exchange assembly 120 before welding, and the relative position between the manifold 122 and the heat exchange tube 121 after welding will no longer change, or it will move slightly within the stress bearing range and elastic deformation range of the heat exchange tube 121 and the manifold 122.

[0069] In the heat exchanger of this embodiment, the partial support assembly 130 close to the welding side 112 must support the heat exchange tube 121 and avoid damage to the support assembly 130 caused by the welding flame. Therefore, before welding the collecting pipe 122 and the heat exchange tube 121, the partial support member 131 close to the welding side 112 should be moved away from the welding position and connected to the frame 115 at the connection position 113 away from the welding side 112 to meet the support requirements for the heat exchange tube 121. After the welding process is completed, the above-mentioned support assembly 130 is moved to the welding side 112, connected to the frame 115 through the connection position 113 of the welding side 112, and can also be fixedly connected to the frame 115 through fasteners.

[0070] In the above-mentioned different embodiments provided in the present application, the support assembly 130 close to the welding side 112 can adjust the connection position 113 between the support assembly 130 and the frame 115 through multiple connection positions 113. Before and during the welding of the heat exchange assembly 120, the support assembly 130 close to the welding side 112 can be moved a certain distance in the direction away from the welding side 112, and connected to the frame 115 through the connection position 113 away from the welding side 112, so as to reduce the burning and damage of the support assembly 130 by the welding flame and the high temperature of welding. When the heat exchange assembly 120 completes the welding process, and during the operation of the heat exchanger 100, the support assembly 130 moves to the welding side 112, and is connected to the frame 115 through the connection position 113 of the welding side 112, so as to form a stable support for the heat exchange assembly 120.

[0071] In the heat exchanger provided in the present application, welding sides 112 can also be set on multiple side surfaces of the frame 115, and multiple welding sides 112 are set on the frame 115, for example, two welding sides 112 are respectively set on opposite sides of the frame 115, wherein one of the welding sides 112 completes the welding process, and the other welding side 112 is used to assist in the installation of the heat exchange tube 121; when the heat exchange tube 121 is long, setting multiple welding sides 112 is beneficial to completing the installation of the heat exchange component 120; wherein most of the heat exchange component 120 is arranged in the frame 115, in order to facilitate the installation and welding of the heat exchange component 120, the elbows in the heat exchange component 120 and the bending areas of the heat exchange tube 121 can be arranged outside the frame 115, located on the welding side 112.

[0072] In one embodiment of the present application, Figure 5 and Figure 6 The support assembly 130 includes a plurality of support members 131, and the plurality of support members 131 are arranged at intervals in the frame 115 to support the heat exchange assembly 120. At least one support member is arranged near the welding side. The heat exchanger 100 in this embodiment is suitable for when the heat exchange tube 121 in the frame 115 is long. The plurality of support members 131 arranged at intervals can prevent the long heat exchange tube 121 from bending and deforming.

[0073] When multiple support members 131 are set to be connected to the heat exchange tube 121, the support member 131 set near the welding side 112 can be flexibly connected to the multiple connection positions 113 of the frame 115. When the heat exchange component 120 is welded, the support member 131 is away from the welding position to reduce the influence of the welding flame. The support members 131 at other positions are far away from the welding position and will not be affected by the welding flame. They can be set to be fixedly connected to the frame 115.

[0074] In one embodiment of the present application, Figure 8 , Fig. 9 , Fig.10 and Fig.11 The support member 131 of the support assembly 130 also includes an outer end plate 133, which is tightly connected to the support plate 132. The outer surface of the outer end plate 133 is provided with an anti-rust layer. Providing the anti-rust layer on the outer end plate 133 can resist the corrosion of the support member 131 by the spray water during the operation of the heat exchanger 100 and the liquid in the external environment. The outer end plate can also be made of stainless steel to reduce rust during long-term operation.
