Description

Technical Field

[0001] This application relates to the field of heat dissipation equipment technology, and in particular to a cabinet assembly and heat exchanger. Background Technology

[0002] The outdoor cabinet houses electronic equipment such as base station equipment, power supply equipment, batteries, and transmission equipment. To ensure that the electronic equipment installed inside can operate normally and reliably within the allowable operating temperature range, the cabinet must have a certain heat dissipation function to transfer the heat generated by the electronic equipment to the outside of the cabinet.

[0003] In traditional technology, to dissipate heat from the electronic equipment inside a server rack, at least one side wall of the rack is configured as a double-layered wall, comprising an inner wall and an outer wall. A continuously alternating pleated plate with grooves and protrusions is installed between the inner and outer walls, isolating the space between them. The space between the outer wall and the pleated plate communicates with the outside of the rack, forming an external airflow duct for air exchange with the outside airflow. The space between the inner wall and the pleated plate communicates with the inside of the rack, forming an internal airflow duct for air exchange with the inside airflow. During heat dissipation, on one hand, the high-temperature airflow inside the rack enters the internal airflow duct and exchanges heat with the low-temperature airflow in the external airflow duct through heat conduction via the pleated plate. This carries the heat from inside the rack to the outside through the airflow in the external airflow duct. On the other hand, the high-temperature airflow inside the rack radiates heat to the outside of the rack through thermal radiation, thus completing the heat dissipation for the electronic equipment inside the rack.

[0004] However, in traditional technology, because the low-temperature airflow outside the cabinet flows through the external circulation duct between the outer wall of the cabinet and the heat-conducting plate, the heat of the high-temperature airflow between the corrugated plate and the inner wall cannot be effectively radiated to the outside of the cabinet, thus reducing the heat dissipation efficiency of the electronic equipment inside the cabinet. Summary of the Invention

[0005] This application provides a cabinet component and heat exchanger to solve the problem that the heat from the high-temperature airflow between the corrugated plate and the inner wall in traditional cabinets cannot be effectively radiated to the outside of the cabinet, thereby reducing the heat dissipation efficiency of electronic equipment inside the cabinet.

[0006] This application provides a heat exchanger for dissipating heat from electronic equipment inside a cabinet. The heat exchanger includes a housing assembly and a heat dissipation pipe array.

[0007] The heat dissipation tube array consists of multiple heat dissipation tubes arranged side by side and spaced apart, and the pipe of each heat dissipation tube forms a first circulation air duct; the outer shell assembly includes a front side plate and a rear side plate respectively disposed on the front side and the rear side of the heat dissipation tube array, and there is a gap between two adjacent heat dissipation tubes in the heat dissipation tube array, and the front side plate and the rear side plate enclose the gap to form a second circulation air duct.

[0008] One of the first and second circulating air ducts is an external circulating air duct that connects to the outside of the cabinet, and the external circulating air duct has an external air inlet and an external air outlet at both ends along its extension direction, both of which are connected to the outside of the cabinet; the other of the first and second circulating air ducts is an internal circulating air duct that connects to the inside of the cabinet, and the internal circulating air duct is sealed at both ends along its extension direction, with an internal air inlet and an internal air outlet on the front panel that connect to the internal circulating air duct, and the rear panel located outside the cabinet.

[0009] The heat exchanger provided in this application embodiment fixes a heat exchange tube array formed by multiple heat dissipation tubes arranged side by side within the outer casing assembly. One of the gaps between each heat dissipation tube and its adjacent heat dissipation tube serves as an external circulation air duct connected to the outside of the cabinet, while the other gap serves as an internal circulation air duct connected to the inside of the cabinet. Furthermore, an internal air inlet and an internal air outlet connected to the internal circulation air ducts are provided on the front panel of the heat exchanger. In this way, the hot airflow inside the cabinet, i.e., the internal circulation airflow, carries the heat from the electronic equipment into each internal circulation air duct through the internal air inlet. The cold airflow outside the cabinet, i.e., the external circulation airflow, enters each external circulation air duct and exchanges heat with the hot airflow in the adjacent internal circulation air duct through the tube walls of the heat dissipation tubes. After the heat from the internal circulation airflow is transferred to the external circulation airflow, the external circulation airflow is then discharged to the outside of the cabinet. The cooled internal circulation airflow then enters the interior, effectively dissipating heat from the electronic equipment inside the cabinet. Compared to traditional technologies, the heat exchanger in this application embodiment increases the heat exchange area, thereby improving the heat dissipation efficiency of the heat exchanger for electronic equipment. On the other hand, the rear panel of the outer casing is located outside the cabinet, and the inner wall of the rear panel is directly attached to the wall of the heat dissipation pipe. In this way, when the heat dissipation pipe is an internal circulation air duct, the internal circulation airflow inside the cabinet directly radiates heat to the outside of the cabinet through the pipe wall and the rear panel. When the gap is used as an internal circulation air duct, the internal circulation airflow can directly radiate heat to the outside of the cabinet through the rear panel. Compared with traditional cabinets, this effectively improves the heat radiation efficiency of the airflow in the internal circulation air duct, thereby improving the heat dissipation efficiency of electronic equipment inside the cabinet.

[0010] In one optional implementation, the first circulating air duct is an external circulating air duct, and the pipe openings at both ends of each heat dissipation pipe are the external air inlet and the external air outlet of the external circulating air duct, respectively.

[0011] The second circulating air duct is an internal circulating air duct, with the gap sealed at both ends along the extension direction, wherein the extension direction of the gap is consistent with the extension direction of the heat dissipation pipe.

[0012] This embodiment of the application uses the first circulating air duct, i.e., the heat dissipation pipe, as the external circulating air duct, and the second circulating air duct, i.e., the gap between adjacent heat dissipation pipes, as the internal circulating air duct. This simplifies the connection structure between the external circulating air duct and the outside of the cabinet. For example, the two ends of the heat dissipation pipe can be directly used as the external air inlet and outlet, respectively, connecting to the outside of the cabinet. Simultaneously, this arrangement also simplifies the connection structure between the internal circulating air duct and the inside of the cabinet. For example, simply connecting the internal air inlet and outlet on the front panel to the gap ensures airflow circulation between the internal circulating air duct and the inside of the cabinet, thereby simplifying the overall structure of the heat exchanger and improving its manufacturing efficiency.

[0013] In one alternative implementation, the internal air inlet and the internal air outlet are respectively located at both ends of the front panel along the extension direction of the internal circulation duct. This extends the airflow path within the cabinet within the internal circulation duct and increases the contact area with the airflow within the external circulation duct. As a result, the heat of the electronic equipment within the cabinet can be effectively transferred to the airflow within the external circulation duct, thereby achieving effective heat dissipation for the electronic equipment.

[0014] In one alternative implementation, the heat exchanger further includes a mounting bracket assembly that is fixed to the housing assembly;

[0015] The heat pipe array is fixed to the housing assembly by a mounting bracket assembly.

[0016] In this embodiment, all the heat pipes in the heat pipe array are fixed to the housing assembly using a fixing bracket. This not only improves the installation stability between the heat pipe array and the housing assembly but also increases the installation efficiency. For example, all the heat pipes on the fixing bracket and the fixing bracket can be integrated into a single structure, and then this integrated structure can be fixed to the housing assembly, making the installation of the heat pipe array more convenient and quick. Furthermore, this fixing bracket design allows for a more compact structure of the heat pipe array within the housing assembly.

[0017] In one alternative implementation, the mounting bracket assembly includes a first mounting bracket and a second mounting bracket, which are located at the two ends of the heat dissipation pipe array near the pipe openings, respectively.

[0018] Both the first and second fixed supports include a top plate. The top plate is provided with interlocking holes at intervals along its extension direction. The interlocking holes divide the top plate into multiple spaced baffles. Multiple heat dissipation pipes are respectively inserted into the corresponding interlocking holes. The baffles are located in the gap between two adjacent heat dissipation pipes. The extension direction of the top plate is consistent with the arrangement direction of the heat dissipation pipes.

[0019] In this embodiment, two fixed brackets are set as top plates with multiple insertion holes, and one end of all heat dissipation pipes in the heat dissipation pipe array is inserted into the corresponding insertion holes. In this way, when all heat dissipation pipes are assembled on the two fixed brackets, a gap can be formed between two adjacent heat dissipation pipes, thereby forming an internal circulation air duct. That is, by assembling the heat dissipation pipes on the first fixed bracket and the second fixed bracket, the formation of the internal circulation air duct in the heat dissipation pipe array is more convenient and faster.

[0020] In one alternative implementation, the opening size of the socket is adapted to the radial size of the heat pipe to limit the sway of each heat pipe in a direction perpendicular to the extension direction of the heat pipe, thereby improving the stability of the internal circulation air duct.

[0021] In one alternative implementation, both the first and second fixed supports include baffles extending downward from both ends of the top plate along the width direction.

[0022] Two baffles are respectively installed on the front and rear sides of the heat dissipation pipe array, wherein the width direction of the top plate is perpendicular to the extension direction of the top plate.

[0023] In this embodiment, a baffle extends from both ends of the top plate along the width direction to block the heat sink array between the two baffles, thereby preventing the heat sinks in the heat sink array from swaying back and forth along the thickness direction and further improving the stability of the heat sink array in the thickness direction. The thickness direction of the heat sink array refers to the direction of the heat sink array that is perpendicular to the extension direction and the arrangement direction of the heat sinks.

[0024] In one alternative implementation, each heat sink in the heat sink array has a limiting part on its sidewall facing at least one baffle.

[0025] The end of the baffle away from the top plate is set on the limiting part to restrict the movement of each heat dissipation pipe in the extension direction, thereby improving the stability of all heat dissipation pipes in the extension direction in the heat dissipation pipe row.

[0026] In one alternative implementation, the limiting part is a step formed on each heat dissipation tube, and the end of the baffle away from the top plate abuts against the step. This ensures that each heat dissipation tube will not come off the first or second fixed bracket, and simplifies the structure of the limiting part, thereby improving the manufacturing efficiency of the entire heat exchanger.

[0027] In one alternative implementation, the heat exchanger further includes two seals, which are respectively disposed at the two ends of the heat dissipation tube bank;

[0028] Each seal includes a sealing plate extending along the arrangement direction of the heat sink tubes in the heat sink tube bank;

[0029] The sealing plate is provided with multiple first clearance openings at intervals along the extension direction. All first clearance openings divide the sealing plate into multiple sealing strips at intervals along the extension direction. One end of each heat dissipation pipe passes through the corresponding first clearance opening. Correspondingly, each sealing strip seals one end of the corresponding gap, so as to effectively seal both ends of all gaps in the heat dissipation pipe array along the extension direction. This not only ensures that each gap in the heat dissipation pipe array forms its own independent internal circulation air duct, so that the airflow in each internal circulation air duct can exchange heat with the airflow in the two adjacent external circulation air ducts on the left and right, thereby improving the heat exchange efficiency of the heat exchanger, but also prevents airflow from flowing between the internal circulation air ducts and between the internal circulation air ducts and the external circulation air ducts. Furthermore, it prevents pollutants such as water vapor in the external environment from entering the internal circulation air ducts and the cabinet through the gaps in the heat dissipation pipe array, thereby preventing damage to the heat exchanger and the electronic equipment in the cabinet.

[0030] In one alternative implementation, the two seals include a first seal and a second seal;

[0031] The first seal is located on the side of the top plate of the first fixed bracket away from the second fixed bracket, and the second seal is located on the side of the top plate of the second fixed bracket away from the first fixed bracket, so as to improve the installation stability of each seal on the heat dissipation tube bank.

[0032] In one alternative implementation, the seal includes any one of rubber, silicone, and plastic components.

[0033] In one alternative implementation, the heat exchanger also includes a clamping element;

[0034] The clamping element is pressed onto the side of the seal that is away from the top plate to improve the stability of the seal at both ends of the gap in the heat dissipation tube array, thereby ensuring the sealing effect of the seal at both ends of the gap.

[0035] In one alternative implementation, the clamping element includes a clamping plate extending along the arrangement direction of the heat sinks in the heat sink array;

[0036] The clamping plate is fixed to the sealing element. The clamping plate has multiple second clearance openings spaced apart along the extension direction. All the second clearance openings divide the clamping plate into multiple clamping strips spaced apart along the extension direction. The pipe openings of all heat dissipation pipes are correspondingly set with the multiple second clearance openings. Accordingly, all the clamping strips are pressed onto the corresponding sealing strips. In this way, while ensuring that each sealing strip is stably sealed in the corresponding gap, the pipe openings of each heat dissipation pipe are ensured to be unobstructed, thereby ensuring that the external circulation air duct can smoothly enter and exit the air.

[0037] In one alternative implementation, the clamping member further includes an extension plate connected to at least one of two opposite sides of the clamping plate along its width direction. The extension plate extends away from the seal and is fixed to the front or rear side plate to improve the assembly stability of the clamping member within the heat exchanger. The width direction of the clamping plate is perpendicular to the extension direction of the clamping plate.

[0038] In one alternative implementation, each heat pipe includes any one of flat pipe, inclined pipe, curved pipe, and corrugated pipe to improve the flexibility of heat pipe selection.

[0039] This application embodiment also provides a cabinet assembly, including a cabinet and at least one heat exchanger as described above;

[0040] At least one heat exchanger is located on the outside of any side wall of the cabinet, and the internal circulation duct of the heat exchanger is connected to the inside of the cabinet.

[0041] This embodiment of the application improves the heat dissipation efficiency of electronic equipment inside the cabinet by installing the heat exchanger on the outside of any side wall of the cabinet. Moreover, the heat exchanger can make full use of the side space outside the cabinet, the space along the waterproof cable routing, or the space of the wall-mounted mounting bracket. This not only avoids occupying the space inside the cabinet, but also reduces the size of the cabinet while ensuring heat dissipation efficiency, making the heat exchanger suitable for miniaturized outdoor cabinets.

[0042] In one alternative implementation, the front panel of the heat exchanger is attached to the outer surface of any one side wall of the cabinet body.

[0043] The side wall of the cabinet body has a cabinet air inlet and a cabinet air outlet. The cabinet air inlet and cabinet air outlet are respectively connected to the inner air inlet and inner air outlet on the front side panel. In this way, the hot air inside the cabinet can enter the inner circulation duct of the heat exchanger through the cabinet air inlet, exchange heat with the air in the outer circulation duct, and then enter the cabinet from the cabinet air outlet.

[0044] In one alternative implementation, one sidewall of the cabinet is configured as the front panel of the heat exchanger to simplify the structure of the heat exchanger, improve the assembly efficiency of the cabinet, reduce the overall size of the cabinet assembly, save the space occupied by the cabinet assembly, and also reduce the weight of the cabinet assembly, making the installation of the cabinet assembly more convenient.

[0066] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0067] To dissipate heat from the electronic equipment inside the cabinet, the conventional technique involves setting at least one side wall of the cabinet as a double-walled structure, including an inner wall and an outer wall. A heat-conducting plate is placed between the inner and outer walls. Specifically, the heat-conducting plate can be a corrugated plate with continuously alternating grooves and protrusions. The corrugated plate isolates the space between the inner and outer walls. The space between the outer wall and the corrugated plate is connected to the outside of the cabinet to form an external air circulation duct for exchanging airflow with the outside of the cabinet. The space between the inner wall and the corrugated plate is connected to the inside of the cabinet to form an internal air circulation duct for exchanging airflow with the inside of the cabinet.

[0068] The outer wall of the cabinet is equipped with an external air inlet and an external air outlet, both of which are connected to the outside of the cabinet and the external circulation duct. In this way, the airflow outside the cabinet can enter the external circulation duct through the external air inlet, exchange heat with the airflow in the internal circulation duct, and then enter the outside of the cabinet through the external air outlet, realizing the circulation of external airflow between the external circulation duct and the external environment of the cabinet.

[0069] Meanwhile, an internal air inlet and an internal air outlet are provided on the inner wall of the cabinet. Both the internal air inlet and the internal air outlet are connected to the electronic equipment and the internal circulation duct inside the cabinet. In this way, the airflow inside the cabinet can enter the internal circulation duct through the internal air inlet, exchange heat with the airflow in the external circulation duct, and then enter the cabinet from the internal air outlet, realizing the circulation of internal airflow between the internal circulation duct and the cabinet.

[0070] During the heat dissipation process of electronic equipment in the server rack, on the one hand, the high-temperature airflow inside the rack, i.e., the internal circulation airflow, enters the internal circulation duct. This internal circulation airflow exchanges heat with the low-temperature airflow in the external circulation duct, i.e., the external circulation airflow, through the heat conduction of the pleated plate. For example, the internal circulation airflow first transfers heat to the surface of the pleated plate facing the inner wall, and then the heat is conducted through the pleated plate to the surface of the pleated plate facing the outer wall. The heat on the surface of the pleated plate facing the outer wall is then transferred to the external circulation airflow in the external circulation duct. After being heated, the external circulation airflow flows out of the rack through the air outlet on the outer wall of the rack. After the internal circulation airflow cools down, it enters the rack through the inner air outlet on the inner wall of the rack. In this way, the heat inside the rack is carried out to the outside of the rack by the airflow in the external circulation duct, thus achieving heat dissipation for the electronic equipment inside the rack.

[0071] On the other hand, the high-temperature airflow inside the cabinet radiates heat to the outside of the cabinet through thermal radiation, thus completing the heat dissipation of the electronic equipment inside the cabinet.

[0072] However, in traditional server racks, the side of the corrugated panel facing the inner wall is an internal circulation duct, through which the airflow inside the rack flows (internal circulation airflow). The side of the corrugated panel facing the outer wall is an external circulation duct, through which the airflow outside the rack flows (external circulation airflow). In other words, there is a certain gap between the corrugated panel and the outer wall of the rack. This isolates the high-temperature airflow inside the rack from the outside of the rack through air, preventing the high-temperature airflow inside the rack from effectively radiating heat directly to the outside of the rack, thus reducing the heat dissipation efficiency of the electronic equipment inside the rack.

[0073] In addition, when installing the corrugated panel, there is a certain amount of installation space between it and the inner wall, outer wall, left side wall and right side wall between the inner and outer walls of the cabinet, which reduces the utilization rate of the heat dissipation space.

[0074] Based on this, this application provides a cabinet assembly and a heat exchanger. A heat exchanger array formed by multiple parallel heat dissipation pipes is fixed inside the outer casing assembly. One of the gaps between each heat dissipation pipe and its adjacent pipe serves as an external circulation duct connected to the outside of the cabinet, and the other gap serves as an internal circulation duct connected to the inside of the cabinet. Furthermore, an internal air inlet and an internal air outlet connected to the internal circulation ducts are provided on the front panel of the heat exchanger. In this way, the hot airflow inside the cabinet (i.e., the internal circulation airflow) carries the heat from the electronic equipment into each internal circulation duct through the internal air inlet. The cold airflow outside the cabinet (i.e., the external circulation airflow) enters each external circulation duct and exchanges heat with the hot airflow in the adjacent internal circulation ducts through the pipe walls of the heat dissipation pipes. After the heat from the internal circulation airflow is transferred to the external circulation airflow, the external circulation airflow is then discharged to the outside of the cabinet, effectively dissipating heat from the electronic equipment inside the cabinet. Compared to traditional technologies, the heat exchanger in this application increases the heat exchange area, thereby improving the heat dissipation efficiency of the heat exchanger for electronic equipment. On the other hand, the rear panel of the outer casing is located outside the cabinet, and the inner wall of the rear panel is directly attached to the wall of the heat dissipation pipe. In this way, when the heat dissipation pipe is an internal circulation air duct, the internal circulation airflow inside the cabinet directly radiates heat to the outside of the cabinet through the pipe wall and the rear panel. When the gap is used as an internal circulation air duct, the internal circulation airflow can directly radiate heat to the outside of the cabinet through the rear panel. Compared with traditional cabinets, this effectively improves the heat radiation efficiency of the airflow in the internal circulation air duct, thereby improving the heat dissipation efficiency of electronic equipment inside the cabinet.

[0075] The specific structure of the heat exchanger and cabinet in the embodiments of this application will be described in detail below.

[0076] Example 1

[0077] Figure 1 This is a schematic diagram of the overall structure of the heat exchanger provided in the embodiments of this application. Figure 2 yes Figure 1 Explosion diagram, Figure 3 This is a structural schematic diagram of the cabinet component provided in an embodiment of this application. (Refer to...) Figures 1 to 3 As shown in the figure, this application embodiment provides a heat exchanger 100, which is used to dissipate heat from the electronic equipment 210 inside the cabinet 200 to ensure that the electronic equipment 210 can operate normally and reliably.

[0078] Figure 4 yes Figure 1 Schematic diagram of the heat dissipation pipe array. Figure 5 yes Figure 4 A magnified view of section I in the middle. (Refer to...) Figure 2 , Figure 4 and Figure 5As shown, the heat exchanger 100 of this embodiment includes a housing assembly 110 and a heat dissipation tube array 120. Referring to... Figure 4 and Figure 5 As shown, the heat sink 120 is composed of multiple heat sinks 121 arranged side by side and spaced apart.

[0079] In specific configurations, the heat dissipation pipe 121 in this application embodiment can be any one of flat pipes, inclined pipes, curved pipes, and corrugated pipes, to improve the flexibility of heat dissipation pipe 121 selection. This application embodiment is specifically described using a flat pipe as an example of heat dissipation pipe 121. The structures of other types of heat dissipation pipes 121, such as inclined pipes, curved pipes, and corrugated pipes, can be directly referred to the prior art.

[0080] The heat dissipation pipe 121 in this embodiment can be formed by extruding profiles of metal materials such as aluminum and copper. This embodiment is specifically described using an aluminum pipe as an example.

[0081] It is worth noting that in the heat pipe array 120, the extension direction of each heat pipe 121 is consistent. For example, referring to... Figure 4 As shown, the extension direction of each heat pipe 121 points towards the height direction of the heat pipe array (e.g., Figure 4 (As shown in the z-direction). Furthermore, for ease of description, in this embodiment, the arrangement direction of the heat dissipation pipes 121 in the heat dissipation pipe array 120 is taken as the width direction of the heat dissipation pipe array 120, such as... Figure 4 As shown in the x-direction, the thickness direction of the heat sink 120 is as follows. Figure 4 As shown in the y-direction. In this embodiment of the application, the pipe 123 of each heat dissipation pipe 121 forms a first circulating air duct.

[0082] Reference Figure 2 As shown, the housing assembly 110 of this application embodiment includes a front side plate 111 and a rear side plate 112 respectively attached to the front and rear sides of the heat dissipation pipe array 120. The front and rear sides of the heat dissipation pipe array 120 are respectively located along the thickness direction (e.g., ...) of the heat dissipation pipe array 120. Figure 2 The two sides of the housing assembly 110 are arranged opposite each other (as shown in the y-direction). The front side plate 111 of the housing assembly 110 is provided on the front side of the heat sink 120, and the rear side plate 112 of the housing assembly 110 is provided on the rear side of the heat sink 120.

[0083] Reference Figure 5 As shown, since the multiple heat dissipation pipes 121 in the heat dissipation pipe array 120 are spaced apart along the x-direction, there is a gap 122 between two adjacent heat dissipation pipes 121 in the heat dissipation pipe array 120. The front side plate 111 and the rear side plate 112 of the outer casing assembly 110 enclose all the gaps 122 in the heat dissipation pipe array 120 to form a second circulating air duct. The rear side plate 112 is located outside the cabinet 200 (e.g., ...). Figure 3(As shown).

[0084] In this embodiment, the first circulating air duct is an external circulating air duct 125 connected to the outside of the cabinet 200. This external circulating air duct 124 has an external air inlet 1251 and an external air outlet 1252 at both ends along its extending direction. (Refer to...) Figure 1 As shown, for example, one port of each heat dissipation pipe 121 can serve as the external air inlet 1251 of the external circulation air duct 125, and the other port of each heat dissipation pipe 121 can serve as the external air outlet 1252 of the external circulation air duct 125. For example, the bottom port of each heat dissipation pipe 121 serves as the external air inlet 1251, and the top port of each heat dissipation pipe 121 serves as the external air outlet 1252.

[0085] It should be noted that, in the actual manufacturing process, the heat exchanger 100 of this application embodiment does not exclude the possibility of opening through holes in the tube wall of each heat dissipation tube 121 as a structure connecting the external air inlet 1251 and the external air outlet 1252.

[0086] It is understandable that since the external air inlet 1251 and the external air outlet 1252 are connected to the external circulation duct 125, and the external circulation duct 125 is connected to the outside of the cabinet 200, both the external air inlet 1251 and the external air outlet 1252 are connected to the external circulation duct 125 and the outside of the cabinet 200. In other words, the external air inlet 1251 enables the connection between the external circulation duct 125 and the external environment of the cabinet 200, and the external air outlet 1252 also enables the connection between the external circulation duct 125 and the external environment of the cabinet 200.

[0087] Reference Figure 1 and Figure 4 As shown, when the heat exchanger 100 of this application embodiment dissipates heat from the electronic equipment 210 inside the cabinet 200, the airflow outside the cabinet 200 will enter the corresponding external circulation duct 125 through one of the ports (e.g., external air inlet 1251) of each heat exchanger pipe 121 in the heat exchanger pipe row 120. After exchanging heat with the airflow in the internal circulation duct 124 mentioned below, the airflow will be discharged from the outside of the cabinet 200 through the other port (e.g., external air outlet 1252) of each heat exchanger pipe 121.

[0088] Based on the above, it can be seen that, Figure 3 As shown, the airflow outside the cabinet 200 will circulate between the outside of the cabinet 200 and the external circulation air duct 125. Therefore, in this embodiment, the airflow outside the cabinet 200 is used as the external circulation airflow b.

[0089] Reference Figure 5As shown, the second circulating air duct in this embodiment is an internal circulating air duct 124 that communicates with the outside of the cabinet 200, wherein both ends of the internal circulating air duct 124 are sealed along the extension direction. The front panel 111 in this embodiment has an internal air inlet 1111 and an internal air outlet 1112 that communicate with the internal circulating air duct 124.

[0090] Since the front side panel 111 and the rear side panel 112 of the outer casing assembly 110 respectively block the front and rear openings of each gap 122, when the gap 122 is an internal circulation air duct 124, the internal air inlet 1111 and the internal air outlet 1112 can be connected to the side opening of the gap 122. At the same time, both ends of each gap 122 in the heat dissipation pipe row 120 along the extension direction are sealed. Thus, each gap 122, which serves as the internal circulation air duct 124, is connected to the interior of the cabinet 200 through the side internal air inlet 1111 and the internal air outlet 1112.

[0091] Specifically, since the internal air inlet 1111 and internal air outlet 1112 on the front panel 111 are both connected to the internal circulation duct 124, and the internal circulation duct 124 is connected to the interior of the cabinet 200, the internal air inlet 1111 and internal air outlet 1112 are both connected to the internal circulation duct 124 and the interior of the cabinet 200. In other words, the internal air inlet 1111 achieves the connection between the internal circulation duct 124 and the interior of the cabinet 200, and the internal air outlet 1112 also achieves the connection between the internal circulation duct 124 and the interior of the cabinet 200.

[0092] Wherein, the extending direction of the gap 122 is consistent with the extending direction of the heat sink 121, such as Figure 5 As shown in the z-direction. Additionally, the openings on the front and rear sides of the gap 122 refer to the gap 122 along the thickness direction of the heat sink 120 (e.g., ...). Figure 5 Two openings are set opposite each other (as shown in the y-direction).

[0093] When the heat exchanger 100 of this embodiment dissipates heat from the electronic equipment 210 inside the cabinet 200, the airflow inside the cabinet 200 enters each internal circulation air duct 124 (i.e., the gap 122 between two adjacent heat dissipation pipes 121) from the internal air inlet 1111. After heat exchange with the airflow in the two external circulation air ducts 125 adjacent to the internal circulation air duct 124 (i.e., the two heat dissipation pipes 121 adjacent to one of the gaps 122), the airflow enters the interior of the cabinet 200 from the internal air outlet 1112.

[0094] Based on the above, it can be seen that, Figure 3 As shown, the airflow inside the cabinet 200 will circulate within the cabinet 200 and the internal circulation air duct 124. Therefore, in this embodiment, the airflow inside the cabinet 200 is referred to as the internal circulation airflow a.

[0095] The heat exchanger 100 in this embodiment of the application dissipates heat from the electronic equipment 210 inside the cabinet 200 as follows:

[0096] Hot airflow inside the rack 200 enters the internal circulation ducts 124 of the heat exchanger 100 through the internal air inlet 1111 of the front panel 111. Simultaneously, cold airflow outside the rack 200 enters the external circulation ducts 125 through the external air inlets 1251 of the heat exchanger 100. Firstly, the heat from the airflow in each internal circulation duct 124 is transferred to the pipe walls on both sides of the duct, and then through heat conduction to the inner walls of the two adjacent heat dissipation pipes 121. Finally, the heat is transferred to the inner walls of the two adjacent heat dissipation pipes. In the airflow within the pipe 123 of the heat pipe 121, i.e. the external circulation airflow b, after being heated, is discharged from the outlet 1252 of the external circulation airflow 125 to the outside of the cabinet 200. The internal circulation airflow a, after being cooled, enters the cabinet from the inner outlet 1112 of the internal circulation airflow 124. This completes the heat exchange between the internal circulation airflow a and the external circulation airflow b in the heat exchanger 100, allowing the heat of the electronic equipment 210 inside the cabinet 200 to be discharged to the outside of the cabinet 200 through the external circulation airflow b, thereby achieving heat dissipation for the electronic equipment 210.

[0097] On the other hand, the airflow in each internal circulation duct 124 radiates heat directly to the outside of the cabinet 200 through the rear side panel 112 in the form of thermal radiation, thereby achieving effective heat dissipation of the electronic equipment 210 inside the cabinet 200.

[0098] Since each gap 122 is formed by the pipe walls of two adjacent heat dissipation pipes 121, the airflow in each inner circulation air duct 124 achieves heat exchange with the airflow in the two adjacent outer circulation air ducts 125 through the pipe walls of the two adjacent heat dissipation pipes 121. Compared with the traditional cabinet 200, the heat exchange area of ​​the inner and outer circulation airflow is increased, thereby improving the heat exchange efficiency of the heat exchanger 100.

[0099] The heat exchanger 100 of this application embodiment can adjust the number of heat dissipation pipes 121 according to actual needs. For example, in the heat exchanger 100 of this application embodiment, the number of heat dissipation pipes 121 can be a suitable discrete value such as 4, 6, 8, 10, etc. In this way, in the application scenario of small cabinet 200, the number of heat dissipation pipes 121 in the heat exchanger 100 can be reduced. While ensuring the heat dissipation efficiency of the heat exchanger 100 for electronic equipment 210, the volume and weight of the heat exchanger 100 and the overall cabinet 200 are reduced. This not only saves the space occupied by the heat exchanger 100 on the cabinet 200, thereby saving the installation space of the cabinet 200, but also makes the transportation and installation of the heat exchanger 100 and the cabinet 200 more convenient and faster.

[0100] Meanwhile, compared with traditional technologies, the heat exchanger 100 of this application encapsulates the heat dissipation tube array 120 into an independent integral structure through the outer shell assembly 110, which is independent of the cabinet body 200 mentioned below, and has a compact structure. Furthermore, each heat dissipation tube 121 of the heat exchanger 100 is formed by extrusion molding of profiles, which simplifies the mold making process, thereby simplifying the manufacturing process of the heat exchanger 100, resulting in high manufacturing yield and low cost.

[0101] Additionally, refer to Figure 3 As shown, the rear panel 112 of the outer casing assembly 110 is located outside the cabinet 200, and the inner wall of the rear panel 112 is in direct contact with the airflow in the inner circulation duct 124. In this way, the airflow in the inner circulation duct 124 can directly radiate heat to the outside of the cabinet 200 through the rear panel 112. Compared with the traditional cabinet 200, the heat radiation efficiency of the airflow in the inner circulation duct 124 is effectively improved, thereby improving the heat dissipation efficiency of the electronic equipment 210 in the cabinet 200.

[0102] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, the inner air inlet 1111 and the inner air outlet 1112 on the front side panel 111 can be respectively set at both ends of the inner circulation duct 124 along the extension direction. For example, the inner air inlet 1111 on the front side panel 111 is set at the top of the front side panel 111, and the inner air outlet 1112 on the front side panel 111 is set at the bottom of the front side panel 111. In this way, the airflow inside the cabinet 200 can enter the top of the inner circulation duct 124 from the inner air inlet 1111 at the top, exchange heat with the outer circulation airflow in the heat exchanger 100, and then enter the cabinet 200 from the inner air outlet 1112 at the bottom. This extends the flow path of the airflow in the cabinet 200 in the inner circulation duct 124 and increases the contact area with the airflow in the outer circulation duct 125. As a result, the heat of the electronic equipment 210 in the cabinet 200 can be effectively transferred to the airflow in the outer circulation duct 125, thereby achieving effective heat dissipation of the electronic equipment 210.

[0103] The top and bottom of the front panel 111 refer to the extension direction of the front panel 111 along the heat dissipation pipe 121 (e.g., Figure 2 The two ends of (as shown in the z-direction).

[0104] Understandably, when the internal air inlet 1111 on the front side panel 111 is located at the top of the front side panel 111 and the internal air outlet 1112 on the front side panel 111 is located at the bottom of the front side panel 111, the bottom pipe opening of the heat dissipation pipe array 120 can be used as the external air inlet 1251 of the external circulation air duct 125, and the top pipe opening of the heat dissipation pipe array 120 can be used as the external air outlet 1252 of the external circulation air duct 125. In this way, the airflow outside the cabinet 200 will flow from the bottom to the top of the external circulation air duct 125, while the airflow in the internal circulation air duct 124 of the heat exchanger 100 will flow from the top to the bottom. This can effectively increase the heat exchange efficiency between the external circulation airflow and the internal circulation airflow.

[0105] Of course, in other examples, the inner air inlet 1111 on the front side panel 111 can also be set at the bottom of the front side panel 111, and the inner air outlet 1112 on the front side panel 111 can be set at the top of the front side panel 111. Correspondingly, the top pipe opening of the heat dissipation pipe array 120 is used as the outer air inlet 1251 of the outer circulation air duct 125, and the bottom pipe opening of the heat dissipation pipe array 120 is used as the outer air outlet 1252 of the outer circulation air duct 125. In this embodiment, the flow direction of the outer circulation airflow and the inner circulation airflow is not specifically restricted.

[0106] To increase the flow efficiency of the external circulating airflow, the heat exchanger 100 in this embodiment may further include a fan. The fan is disposed on the external circulating air duct 125 to improve the flow efficiency of the external circulating air duct 125 and the external airflow of the cabinet 200, thereby improving the heat dissipation efficiency of the hot airflow inside the internal circulating air duct 124.

[0107] In specific configuration, there can be one fan, located at the top or bottom of the housing assembly 110 and at the external air inlet 1251 of any one of the external circulation ducts 125. In other words, all external circulation ducts 125 share one fan. This fan ensures that the heated airflow within the external circulation duct 125 is smoothly exhausted to the outside of the cabinet 200 through the external air outlet 1252, preventing the heat from remaining in the external circulation duct 125 and then entering the cabinet 200 through the internal circulation airflow, thus affecting the heat dissipation of the electronic equipment 210.

[0108] The fan can also quickly guide the cold air outside the cabinet 200 into the external circulation duct 125, where it exchanges heat with the hot air in the internal circulation duct 124, thereby improving the circulation efficiency of the external circulation air between the external circulation duct 125 and the outside of the cabinet 200.

[0109] In other examples, the number of fans can be the same as the number of external circulation ducts 125, i.e., heat dissipation pipes 121. For example, a fan is provided at the external air inlet 1251 of each external circulation duct 125 to further improve the flow efficiency of airflow in each external circulation duct 125, thereby improving the heat dissipation efficiency of the heat exchanger 100 in this embodiment of the application.

[0110] Figure 6 yes Figure 1 Assembly diagram of the heat dissipation pipe array and mounting bracket assembly. Figure 7 yes Figure 6 A partial structural diagram. Figure 8 yes Figure 1 Assembly drawing of the first fixed bracket and the outer casing assembly. (Refer to...) Figures 6 to 8 As shown, the heat exchanger 100 in this embodiment may further include a fixing bracket assembly 130. The fixing bracket assembly 130 is fixed to the housing assembly 110, and all the heat dissipation pipes 121 in the heat dissipation pipe row 120 are fixed to the housing assembly 110 through the fixing bracket assembly 130.

[0111] For example, during assembly, all the heat dissipation pipes 121 of the heat dissipation pipe array 120 can be pre-fixed to the fixing bracket assembly 130. In this way, all the heat dissipation pipes 121, i.e. the heat dissipation pipe array 120 and the fixing bracket assembly 130 can be used as a whole structure. Then, the whole structure can be fixed to the housing assembly 110, making the installation of the heat dissipation pipe array 120 more convenient and quick, thereby improving the installation efficiency between the heat dissipation pipe array 120 and the housing assembly 110, and also facilitating the replacement of the heat dissipation pipe array 120.

[0112] Meanwhile, all the heat dissipation pipes 121 of the heat dissipation pipe array 120 are fixed to the outer casing assembly 110 by the fixing bracket assembly 130, which improves the installation stability between the heat dissipation pipe array 120 and the outer casing assembly 110. In addition, the fixing bracket assembly 130 makes the structure of the heat dissipation pipe array 120 inside the outer casing assembly 110 more compact.

[0113] In specific assembly, the fixing bracket assembly 130 can be fixed to the front side plate 111 or the rear side plate 112 of the outer shell assembly 110. Alternatively, the fixing bracket assembly 130 can be fixed to the outer shell assembly 110 by means of screws, rivets, snap-fits, or welding. This embodiment does not specifically limit the fixing method between the fixing bracket assembly 130 and the outer shell assembly 110, as long as the installation stability between the fixing bracket assembly 130 and the outer shell assembly 110 is ensured.

[0114] All heat pipes 121 in the heat pipe row 120 can be fixed to the fixing bracket assembly 130 by means of screws, rivets, snaps or welding. This application embodiment does not specifically limit the fixing method between the heat pipes 121 and the fixing bracket assembly 130.

[0115] Figure 9 yes Figure 6 A schematic diagram of the structure of the first fixed bracket. Figure 10 yes Figure 7 A partial structural diagram. (Refer to...) Figure 6 , Figure 9 and Figure 10 As shown, in a specific implementation, the fixed bracket assembly 130 of this application embodiment includes two fixed brackets, namely a first fixed bracket 131 and a second fixed bracket 132. The first fixed bracket 131 and the second fixed bracket 132 are respectively located at the two ends of the heat dissipation pipe row 120 near the pipe opening. In this application embodiment, the first fixed bracket 131 is set at the top of the heat dissipation pipe row 120 and the second fixed bracket 132 is set at the bottom of the heat dissipation pipe row 120 as an example for explanation.

[0116] Reference Figure 8 and Figure 9 As shown, both the first fixed bracket 131 and the second fixed bracket 132 include a top plate 133, which is aligned with the arrangement direction of the heat dissipation pipes 121 in the heat dissipation pipe array 120 (e.g., ...). Figure 6 Extending in the x-direction, the top plate 133 is fixed to the housing assembly 110 (as shown in the x-direction). Figure 8 As shown), for example, the two ends of the top plate 133 can be fixed to the front side plate 111 or the rear side plate 112 of the housing assembly 110 by means of screws or the like.

[0117] Reference Figure 9 and Figure 10 As shown, the top plate 133 is provided with interlocking holes 1331 at intervals along its extension direction. The interlocking holes 1331 divide the top plate 133 into multiple spaced baffles 1332. It can be understood that each interlocking hole 1331 has baffles 1332 on both sides. Multiple heat dissipation pipes 121 in the heat dissipation pipe row 120 are respectively inserted into the corresponding interlocking holes 1331, and the baffles 1332 are located in the gaps 122 between two adjacent heat dissipation pipes 121.

[0118] It should be understood that the two top plates 133 of the fixed bracket assembly 130 are respectively disposed at both ends of the heat dissipation pipe row 120 near the pipe opening. The extension direction of each top plate 133 is consistent with the arrangement direction of the heat dissipation pipes 121 in the heat dissipation pipe row 120.

[0119] In this embodiment, the number of insertion holes 1331 on the top plate 133 is greater than or equal to the number of heat dissipation pipes 121 in the heat dissipation pipe array 120, so as to ensure that one end of each heat dissipation pipe 121 can be inserted into the corresponding insertion hole 1331.

[0120] For example, the number of sockets 1331 on the top plate 133 can be set to be equal to the number of heat dissipation pipes 121. In this way, each heat dissipation pipe 121 on the heat dissipation pipe row 120 can be set to correspond one-to-one with the sockets 1331 on the top plate 133, so as to save the length of the top plate 133.

[0121] In this embodiment, both the first fixed bracket 131 and the second fixed bracket 132 are configured as a top plate 133 with multiple insertion holes 1331, and one end of all the heat dissipation pipes 121 in the heat dissipation pipe row 120 is inserted into the corresponding insertion holes 1331. In this way, when all the heat dissipation pipes 121 are assembled on the two fixed brackets, namely the first fixed bracket 131 and the second fixed bracket 132, a gap 122 can be formed between two adjacent heat dissipation pipes 121, thereby forming an internal circulation air duct 124. That is, by assembling the heat dissipation pipes 121 on the fixed bracket assembly 130, such as the first fixed bracket 131 and the second fixed bracket 132, the formation of the internal circulation air duct 124 in the heat dissipation pipe row 120 is more convenient and faster.

[0122] In specific configuration, the opening size of the socket 1331 is adapted to the radial dimension of the heat sink 121. This allows the outer wall of the heat sink 121 to fit tightly against the inner wall of the socket 1331. In other words, the wall of the socket 1331 restricts the direction of each heat sink 121 perpendicular to its extension direction (see reference). Figure 6 The swaying in the x and y directions (as shown in the middle) improves the stability of the heat pipe 121 within the socket 1331.

[0123] Specifically, the shape of the socket 1331 matches the cross-sectional shape of the heat pipe 121, and the radial dimension of the socket 1331 is consistent with the cross-sectional dimension of the heat pipe 121. For example, when the cross-sectional shape of the heat pipe 121 is circular, the shape of the socket 1331 is also circular, and the diameter of the socket 1331 is consistent with the cross-sectional diameter of the heat pipe 121.

[0124] Continue to refer to Figure 9 and Figure 10 As shown, in this embodiment of the application, both the first fixing bracket 131 and the second fixing bracket 132 can include a bracket extending from the top plate 133 along the width direction (e.g., Figure 10The baffles 134 extend downward from both ends of the top plate 133 (as shown in the y-direction). Taking the first fixed bracket 131 as an example, baffles 134 are provided at both ends of the top plate 133 of the first fixed bracket 131 along the width direction. The two baffles 134 are respectively provided on the front and rear sides of the heat dissipation pipe row 120. The width direction of the top plate 133 is perpendicular to the extension direction of the top plate 134.

[0125] Among them, the two baffles 134 on the first fixed bracket 131 extend toward the second fixed bracket 132, and the two baffles 134 on the second fixed bracket 132 extend toward the first fixed bracket 131.

[0126] In this embodiment, a baffle 134 extends from both ends of the top plate 133, which are opposite each other in the width direction, to block the heat sink 120 between the two baffles 134, thereby further preventing the heat sink 121 in the heat sink 120 from extending along the thickness direction (refer to the thickness direction). Figure 10 (As shown in the y-direction) It sways back and forth, which further improves the stability of the heat sink 120 in the thickness direction.

[0127] Taking the first fixed bracket 131 as an example, the top plate 133 and the baffle 134 of the first fixed bracket 131 can be integrally formed. This not only simplifies the structure of the first fixed bracket 131 and improves the installation process between the first fixed bracket 131 and the heat dissipation tube row 120 and the outer shell assembly 110, but also enhances the structural strength of the first fixed bracket 131, thereby further ensuring the fixing effect of the first fixed bracket 131 on the heat dissipation tube row 120, and also improving the structural stability of the entire heat exchanger 100.

[0128] Of course, this application embodiment does not exclude the arrangement in which the top plate 133 and the baffle 134 of the first fixed bracket 131 are detachably connected.

[0129] In the heat dissipation pipe array 120 of this application embodiment, each heat dissipation pipe 121 has a limiting portion on its side wall facing at least one baffle 134. The end of the baffle 134 away from the top plate 133 is disposed on the limiting portion to restrict the extension direction of each heat dissipation pipe 121 (e.g., Figure 10 The movement in the z-direction (as shown) improves the stability of all heat pipes 121 in the heat pipe row 120 in the extension direction (i.e., the height direction of the heat pipe row 120).

[0130] Reference Figure 10 As shown, in a specific implementation, the limiting part can be a step 126 formed on each heat dissipation pipe 121, and the end of the baffle 134 away from the top plate 133 abuts against the step 126. This ensures that each heat dissipation pipe 121 will not come off any fixed bracket, and simplifies the structure of the limiting part, thereby improving the manufacturing efficiency of the entire heat exchanger 100.

[0131] For example, a step 126 can be provided on the side wall near the top of each heat pipe 121, and the bottom end of the baffle 134 of the first fixed bracket 131 abuts against the step 126. This restricts all heat pipes 121 in the heat pipe row 120 from moving upward in the z direction, thereby preventing all heat pipes 121 in the heat pipe row 120 from coming off the top of the first fixed bracket 131.

[0132] Additionally, a step 126 can be provided on the side wall near the bottom of each heat pipe 121, and the top of the baffle 134 of the second fixed bracket 132 abuts against the step 126. This restricts all heat pipes 121 in the heat pipe row 120 from moving downward in the z direction, thereby preventing all heat pipes 121 in the heat pipe row 120 from coming off the bottom of the second fixed bracket 132.

[0133] The steps 126 on the heat sink 121 can be manufactured in various ways. For example, a protruding structure can be pre-formed on the outer wall of the heat sink 121, with the extension direction of the protruding structure aligned with the extension direction of the heat sink 121. Then, the portions of the protruding structure at both ends of the heat sink 121 are removed by machining, thus forming the steps 126 at both ends of the heat sink 121. Alternatively, a step can be punched at both ends of the heat sink 121 to close the gap, or the wall thickness of the heat sink 121 can be increased before machining into steps 126. Of course, in other examples, a step 126 can also be welded, riveted, or pressed onto the outer wall of the heat sink 121. This application does not specifically limit the manufacturing method of the steps 126.

[0134] Figure 11 yes Figure 1 A partial structural diagram of the inner shell assembly. (Refer to...) Figure 11 As shown, the housing assembly 110 of this application embodiment may further include a left side plate 113 and a right side plate 114 disposed opposite to each other. The left side plate 113 and the right side plate 114 are respectively disposed between the front side plate 111 and the rear side plate 112. For example, the two ends of the left side plate 113 and the right side plate 114 along the thickness direction of the heat dissipation pipe row 120 are respectively fixed on the front side plate 111 and the right side plate 114.

[0135] Reference Figure 2 As shown, the left side plate 113 and the right side plate 114 of the housing assembly 110 are respectively disposed on the left side and right side of the heat dissipation pipe array 120, wherein the left side and the right side are respectively the width direction of the heat dissipation pipe array 120 along the arrangement direction of the heat dissipation pipes 121 (i.e., the width direction of the heat dissipation pipe array 120). Figure 2 (As shown in the x-direction) Two sides are set opposite each other.

[0136] This embodiment of the application provides a left side plate 113 and a right side plate 114 between the front side plate 111 and the rear side plate 112 of the housing assembly 110, and sets the left side plate 113 and the right side plate 114 on the left and right sides of the heat dissipation tube array 120, respectively. This allows the heat dissipation tube array 120 to be placed within the installation space formed by the left side plate 113, the right side plate 114, the front side plate 111, and the rear side plate 112, thereby improving the structural stability of the heat exchanger 100. Furthermore, the housing assembly 110 provides further protection for the heat dissipation tube array 120, preventing it from being damaged by impacts from the external environment and preventing external moisture from entering the heat dissipation tube array 120 from the side, which could cause corrosion or even enter the cabinet 200 through the internal circulation air duct 124.

[0137] In addition, the outer casing assembly 110 is configured as described above, which makes the structure of the entire heat exchanger 100 more compact, thereby reducing the volume of the heat exchanger 100.

[0138] To improve the installation stability between the mounting bracket assembly 130 and the housing assembly 110, both ends of the mounting bracket assembly 130 can be fixed to the left side plate 113 and the right side plate 114 of the housing assembly 110, respectively. For example, the two ends of the first mounting bracket 131 are fixed to the left side plate 113 and the right side plate 114 of the housing assembly 110, respectively, and the two ends of the second mounting bracket 132 are fixed to the left side plate 113 and the right side plate 114 of the housing assembly 110, respectively. In some examples, the two ends of the top plate 133 of each mounting bracket can be welded, snap-fitted, or directly fixed to the left side plate 113 and the right side plate 114 with screws (e.g., ...). Figure 8 (As shown).

[0139] Figure 12 yes Figure 11 A magnified view of section II in the middle. (Refer to...) Figure 11 and Figure 12 As shown, in other examples, the housing assembly 110 of this application embodiment may further include a plurality of mounting supports 115, with each fixed bracket having its two ends along the extension direction fixed to the left side plate 113 and the right side plate 114 respectively via mounting supports 115. For example, a mounting support 115 may be fixed to the inner wall of both the left side plate 113 and the right side plate 114, and the top plates 133 of the first fixed bracket 131 and the second fixed bracket 132 having their two ends along the extension direction fixed to the corresponding mounting supports 115, thereby realizing the assembly connection between each fixed bracket and the housing assembly 110.

[0140] In this embodiment of the application, by providing a mounting bracket 115 on the housing assembly 110, two fixed brackets are fixed to the housing assembly 110 through the mounting bracket 115, which improves the installation stability between the fixed brackets and the housing assembly 110, and also makes the installation and disassembly between the fixed brackets and the housing assembly 110 more convenient, thereby facilitating the removal of the heat dissipation pipe array 120 on the fixed bracket from the housing assembly 110.

[0141] Reference Figure 12 As shown, in some examples, the mounting bracket 115 may include a mounting portion 1151 and a boss 1152 located on the mounting portion 1151. The mounting portion 1151 is fixed to the inner wall of the left side plate 113 or the right side plate 114. The boss 1152 extends away from the left side plate 113 or the right side plate 114. One end of the fixing bracket is fixed to the platform of the boss 1152. For example, one end of the first fixing bracket 131 is fixed to the platform of the boss 1152.

[0142] Taking a mounting bracket 115 installed on the right side plate 114 as an example, the mounting part 1151 of the mounting bracket 115 is fixed on the inner wall of the right side plate 114, and the boss 1152 at one end of the mounting part 1151 extends away from the right side plate 114. One end of the fixing bracket, such as the first fixing bracket 131, is fixed on the boss 1152. For example, one end of the top plate 133 of the first fixing bracket 131 is fixed on the boss 1152 of the mounting bracket 115.

[0143] The boss 1152 can extend outward from the top of the mounting part 1151 or from the bottom of the mounting part 1151. One end of the fixing bracket is fixed on the platform of the boss 1152 to ensure the stability of the fixing bracket on the mounting support 115.

[0144] The mounting bracket 115 in this embodiment can be an integrally formed piece to simplify the structure and assembly process of the mounting bracket 115, while improving the structural strength of the mounting bracket 115.

[0145] In this embodiment of the application, by fixing one end of each fixed bracket to the boss 1152 of the mounting bracket 115, the stability of the fixed bracket on the mounting bracket 115 is improved. At the same time, the mounting part 1151 of the mounting bracket 115 is fixed to the housing assembly 110, so that the mounting bracket 115 is stably fixed to the left side plate 113 or the right side plate 114 of the housing assembly 110.

[0146] Reference Figure 12As shown, exemplarily, the mounting portion 1151 of the mounting bracket 115 in this embodiment can be fixed to the left side plate 113 or the right side plate 114 of the housing assembly 110 by screws. For example, the mounting portion 1151 can be fixed to the left side plate 113 or the right side plate 114 of the housing assembly 110 by three screws, wherein the three screws are distributed at the three vertices of a triangle to improve the connection stability between the mounting bracket 115 and the housing assembly 110. In other examples, the mounting portion 1151 of the mounting bracket 115 can also be fixed to the housing assembly 110 by welding, riveting, snap-fitting, etc., and this embodiment does not limit this.

[0147] Similarly, refer to Figure 8 As shown, one end of the fixing bracket, such as the first fixing bracket 131, can be fixed to the boss 1152 of the mounting bracket 115 with screws, thereby simplifying the fixing structure between the fixing bracket and the mounting bracket 115 and ensuring the stability of the connection between the two. In other examples, one end of the fixing bracket, such as the first fixing bracket 131, can also be fixed to the boss 1152 of the mounting bracket 115 by welding, riveting, or snap-fitting, etc., and this application embodiment does not limit this.

[0148] In the heat dissipation pipe array 120 of this application embodiment, the sealing method for the openings at both ends of all gaps 122 along the extension direction includes, but is not limited to, any one or more of potting, sealing putty, and impregnation, to improve the flexibility of the sealing method and facilitate the sealing of the openings at both ends of the gaps 122. For example, sealant can be poured between the two ends of the outer wall of two adjacent heat dissipation pipes 121 in the heat dissipation pipe array 120 to seal the two ends of all gaps 122, so that each gap 122 forms an independent internal circulation air duct 124, while preventing external moisture and other substances from entering the cabinet 200 through the gaps 122 of the heat dissipation pipe array 120.

[0149] Figure 13 yes Figure 2 Partial exploded view, Figure 14 yes Figure 2 Assembly drawing of heat dissipation pipes, seals, and clamping components. Figure 15 yes Figure 14 A sectional view. (Refer to...) Figures 13 to 15As shown, as one sealing method, the heat exchanger 100 of this embodiment may further include two sealing elements 140, which are respectively disposed at the two pipe ends of the heat dissipation tube bank 120. Each sealing element 140 includes a sealing plate extending along the arrangement direction of the heat dissipation tubes 121 in the heat dissipation tube bank 120. The sealing plate is provided with a plurality of first clearance openings 141 at intervals along the extension direction. All the first clearance openings 141 divide the sealing plate into a plurality of sealing strips 142 at intervals along the extension direction. One end of each heat dissipation tube 121 passes through the corresponding first clearance opening 141. Correspondingly, each sealing strip 142 seals one end of the corresponding gap 122. Each first clearance opening 141 is used to avoid the pipe opening of each heat dissipation tube 121, ensuring that the external circulation air duct 125 is connected to the external environment of the cabinet 200.

[0150] The sealing element 140 ensures that all gaps 122 in the heat exchange tube array 120 are sealed at both ends along the extension direction. This not only ensures that each gap 122 in the heat exchange tube array 120 forms its own independent internal circulation air duct 124, allowing the airflow in each internal circulation air duct 124 to exchange heat with the airflow in the two adjacent external circulation air ducts 125, thereby improving the heat exchange efficiency of the heat exchanger 100, but also prevents cross-flow between the internal circulation air ducts 124 and between the internal circulation air ducts 124 and the external circulation air ducts 125. Furthermore, it prevents pollutants such as water vapor in the external environment from entering the internal circulation air ducts 124 and the cabinet 200 through the gaps 122 in the heat exchange tube array 120, thus avoiding damage to the heat exchanger 100 and the electronic equipment 210 inside the cabinet 200.

[0151] In addition, the two ends of the gap 122 of the heat pipe array 120 are sealed by two seals 140, which facilitates the disassembly of the heat pipe array 120. In this way, when it is necessary to reduce the number of heat pipes 121 in the heat pipe array 120, the two seals 140 can be removed directly, and then a few heat pipes 121 can be removed. Damaged heat pipes 121 can also be replaced at any time.

[0152] It is understandable that the structure of the sealing strip 142 on the sealing plate matches the radial structure of each gap 122 to ensure that the outer periphery of the sealing strip 142 is in close contact with the outer wall of the two adjacent heat dissipation pipes 121.

[0153] In specific installation, the two sealing elements 140 in this embodiment include a first sealing element and a second sealing element. The first sealing element is disposed on the side of the top plate 133 of the first fixed bracket 131 away from the second fixed bracket 132, and the second sealing element is disposed on the side of the top plate 133 of the second fixed bracket 132 away from the first fixed bracket 131, so as to improve the installation stability of the sealing element 140 on the heat dissipation pipe row 120.

[0154] Taking the first fixed bracket 131 located near the top opening of the heat dissipation tube array 120 as an example, the first sealing element is disposed on the side of the top plate 133 of the first fixed bracket 131 facing the top of the heat dissipation tube array 120. For example, the sealing plate of the first sealing element is fixed to the surface of the top plate 133 of the first fixed bracket 131 facing the top of the heat dissipation tube array 120 by means of welding, riveting, screwing, and snapping, so as to further ensure the sealing effect of the first sealing element on all gaps 122 in the heat dissipation tube array 120.

[0155] The first clearance opening 141 on the seal 140 corresponds to the insertion hole 1331 on the top plate 133, ensuring that the end of the heat dissipation pipe 121 passes through the first clearance opening 141 and the insertion hole 1331. The sealing strip 142 on the seal 140 is pressed onto the portion of the top plate 133 located on both sides of the insertion hole 1331, making the sealing strip 142 more secure at the ports of each gap 122.

[0156] In the specific installation of the sealing member 140 in this application embodiment, the side of the sealing member facing away from the fixed bracket can be lower than or flush with the end face of the pipe opening end of the heat dissipation tube bank 120. Taking the first sealing member as an example, the side of the first sealing member facing away from the first fixed bracket 131 is lower than or flush with the top surface of the heat dissipation tube bank 120. That is to say, the thickness of the sealing plate of the first sealing member is less than or equal to the distance between the top plate 133 of the first fixed bracket 131 and the top surface of the heat dissipation tube bank 120. In this way, the overall height of the heat exchanger 100 can be saved, thereby saving the occupied size of the heat exchanger 100.

[0157] Reference Figure 15 As shown, in some examples, the side of the seal 140 facing away from the fixed bracket extends to the end face of the tube opening of the heat sink 120. Continuing with the example of the first seal, the side of the first seal facing away from the first fixed bracket 131 is higher than the top surface of the heat sink 120. That is to say, the thickness of the sealing plate of the first seal is greater than the distance between the top plate 133 of the first fixed bracket 131 and the top surface of the heat sink 120.

[0158] The width of the portion of the sealing strip 142 extending beyond the end of the heat dissipation tube array 120 can be greater than the width of the gap 122, so as to play a positioning role in the assembly of the sealing element 140. For example, during the assembly of the sealing element 140, as long as the sealing strip 142 on the sealing element 140 abuts against the end face of the end of the heat dissipation tube array 120, it is ensured that the sealing element 140 is pressed onto the fixed bracket 130, thereby completing the positioning of the sealing element 140.

[0159] The sealing element 140 in this application embodiment may include, but is not limited to, any one of rubber, silicone, and plastic parts. As one example, the sealing element 140 is a rubber part to ensure that each sealing strip 142 on the sealing element 140 can make tight contact with the outer wall of two adjacent heat dissipation pipes 121, thereby enhancing the sealing effect on the gap 122.

[0160] Additionally, refer to Figures 13 to 15 As shown, the heat exchanger 100 in this embodiment of the application also includes a clamping member 150, which is pressed onto the side of the sealing member 140 away from the fixed bracket 130 to improve the stability of the sealing member 140 at both ends of the gap 122 of the heat dissipation tube row 120, thereby ensuring the sealing effect of the sealing member 140 at both ends of the gap 122.

[0161] The number of clamping components 150 can be one, for example, refer to Figure 14 As shown, a clamping member 150 is provided on one side of the sealing member 140, i.e. the first sealing member, at the top of the heat dissipation tube array 120, and the clamping member 150 is provided on the side of the first sealing member facing the top of the heat dissipation tube array 120, so as to ensure that the first sealing member will not come out of the top tube end of the heat dissipation tube array 120.

[0162] Of course, in some examples, there may be two clamping members 150, one of which is located on the side of the first seal facing the top of the heat sink 120, and the other of which is located on the side of the second seal facing the bottom of the heat sink 120. For ease of description, the clamping member 150 located on the first seal will be referred to as the first clamping member, and the clamping member 150 located on the second seal will be referred to as the second clamping member.

[0163] Reference Figure 13 and Figure 15 As shown, in a specific configuration, the clamping member 150 may include a clamping plate 151 extending along the arrangement direction of the heat dissipation pipes 121 in the heat dissipation pipe array 120. The clamping plate 151 is fixed on the sealing member 140. The clamping plate 151 is provided with a plurality of second clearance openings 1511 at intervals along the extension direction. All the second clearance openings 1511 divide the clamping plate 151 into a plurality of clamping strips 1512 at intervals along the extension direction. The pipe openings of all heat dissipation pipes 121 are correspondingly provided with the plurality of second clearance openings 1511 to ensure that the external circulating airflow circulates between each external circulating air duct 125 in the heat dissipation pipe array 120 and the outside of the cabinet 200.

[0164] Accordingly, all the pressing strips 1512 are pressed onto the corresponding sealing strips 142. This ensures that each sealing strip 142 is stably sealed in the corresponding gap 122 without coming out, while ensuring that the openings of each heat dissipation pipe 121 are unobstructed, thereby ensuring that the external circulation air duct 125 can smoothly enter and exit the air.

[0165] It is understood that when a portion of the sealing strip 142 extends to the end of the heat sink 120, the clamping strip 1512 of this embodiment is also located outside the heat sink 120. When the sealing strip 142 is completely inside the heat sink 120, the clamping strip 1512 of this embodiment can be located inside the heat sink 120, or partially or entirely outside the heat sink 120. This embodiment does not limit the placement of the clamping strip 1512.

[0166] The clamping member 150 can be fixed to the sealing member 140 by screws. In some examples, the clamping member 150 can also be fixed to the sealing member 140 by welding, riveting, snap-fitting, or pressing with an adapter, etc., and this application embodiment does not limit this.

[0167] Furthermore, referring to Figure 13 As shown, the clamping member 150 in this embodiment of the application further includes an extension plate 152, which is connected to at least one of the two sides of the clamping plate 151 that are disposed opposite to each other in the width direction. The extension plate 152 extends away from the seal 140 and is fixed to the front side plate 111 or the rear side plate 112 to improve the assembly stability of the clamping member 150 in the heat exchanger 100.

[0168] Taking the first clamping member as an example, an extension plate 152 is provided on one of the sides of the clamping plate 151 of the first clamping member that is arranged opposite to it in the width direction. The extension plate 152 extends away from the first seal. When the first clamping plate is fixed on the first seal, the extension plate 152 can be fixed on the front side plate 111 or the rear side plate 112 of the housing assembly 110 to further improve the stability of the first clamping member on the first seal, thereby ensuring the stability of the seal 140 on the heat dissipation pipe row 120.

[0169] Of course, in some examples, an extension plate 152 can be provided on each of the two sides of the clamping plate 151 that are opposite to each other in the width direction, and the two extension plates 152 are respectively fixed on the front side plate 111 and the rear side plate 112 of the housing assembly 110.

[0170] Example 2

[0171] Unlike Embodiment 1, in this embodiment, the first circulating air duct is an internal circulating air duct 124 that communicates with the interior of the cabinet 200. That is, the pipe 123 of each heat dissipation pipe 121 in the heat dissipation pipe row 120 serves as the internal circulating air duct 124. The second circulating air duct is an external circulating air duct 125 that communicates with the exterior of the cabinet 200. That is, each gap 122 in the heat dissipation pipe row 120 serves as the external circulating air duct 125.

[0172] Specifically, the internal circulation air duct 124 is sealed at both ends along its extension direction. That is, both ends of each heat dissipation pipe 123 are sealed. A first ventilation opening and a second ventilation opening are provided on the side of each heat dissipation pipe 121 facing the front panel 111. The first ventilation opening connects to the internal air inlet 1111 on the front panel 111, and the second ventilation opening connects to the internal air outlet 1112 on the front panel 111. Thus, the interior of each heat dissipation pipe 123 can circulate air with the interior of the cabinet 200 through the first ventilation opening, the internal air inlet 1111, the second ventilation opening, and the internal air outlet 1112. For example, airflow inside the cabinet 200 enters the heat dissipation pipe 123 (i.e., the internal circulation air duct 124) through the internal air inlet 1111 and the first ventilation opening. After heat exchange with the airflow in the external circulation air duct 125, it returns to the interior of the cabinet 200 through the second ventilation opening and the internal air outlet 1112.

[0173] It is understandable that, since the front side panel 111 is attached to the front side of the heat dissipation pipe array 120, there are multiple internal air inlets 1111 on the front side panel 111. The multiple internal air inlets 1111 are spaced apart along the width direction of the heat dissipation pipe array 120 and are staggered from the gaps 122 in the heat dissipation pipe array 120. At the same time, the multiple internal air inlets 1111 are respectively connected to the first ventilation opening on the corresponding heat dissipation pipe 123.

[0174] Similarly, there are multiple internal air outlets 1112 provided on the front side panel 111. The multiple internal air outlets 1112 are spaced apart along the width direction of the heat dissipation pipe row 120 and are staggered from the gaps 122 in the heat dissipation pipe row 120. At the same time, the multiple internal air outlets 1112 are respectively connected to the second ventilation openings on the corresponding heat dissipation pipes 123.

[0175] The two ends of the heat sink 123 can be sealed by methods such as potting glue, sealing putty, and impregnation, or by the sealing element 140 in Embodiment 1. It is understood that the sealing method for the two ends of the heat sink 123 can directly refer to the sealing method for the two openings along the extension direction of the gap 122 in Embodiment 1, and will not be elaborated further here.

[0176] Regarding the external circulation duct 125, the openings at both ends of each gap 122 along the extension direction can serve as external air inlets 1251 and external air outlets 1252 communicating with the outside of the cabinet 200. Each gap 122 can achieve airflow circulation with the outside of the cabinet 200 through its openings at both ends along the extension direction. For example, airflow from outside the cabinet 200 enters the gap 122, i.e., the external circulation duct 125, through the external air inlet 1251 (e.g., the bottom opening of the gap 122), exchanges heat with the airflow in the internal circulation duct 124, and then returns to the outside of the cabinet 200 through the external air outlet 1252 (e.g., the top opening of the gap 122).

[0177] The heat dissipation process of the heat exchanger 100 on the electronic equipment 210 inside the cabinet 200 in this embodiment of the application is as follows:

[0178] Hot airflow inside the rack 200 enters the internal circulation ducts 124 of the heat exchanger 100 through the internal air inlet 1111 and the first vent on the front panel 111. Simultaneously, cold airflow from outside the rack 200 enters the external circulation ducts 125 through the external air inlets 1251 of the heat exchanger 100. Firstly, the heat from the airflow in each internal circulation duct 124 is transferred to the pipe walls on both sides of the duct, and then through heat conduction to the outer walls of the two adjacent heat dissipation pipes 121. Finally, the heat is transferred to the heat exchanger... In the gap 122 on both sides of the heat pipe 121, which is the airflow in the external circulation duct 125, the external circulation airflow b is heated and discharged from the outlet 1252 of the external circulation duct 125 to the outside of the cabinet 200. The internal circulation airflow a is cooled and enters the cabinet from the inner outlet 1112 of the internal circulation duct 124. This completes the heat exchange between the internal circulation airflow a and the external circulation airflow b in the heat exchanger 100, so that the heat of the electronic equipment 210 inside the cabinet 200 is discharged to the outside of the cabinet 200 through the external circulation airflow b, thereby achieving heat dissipation of the electronic equipment 210.

[0179] On the other hand, since the inner wall of the rear panel 112 is directly attached to the wall of the heat dissipation pipe 121, the internal circulating airflow a inside the cabinet 200 can directly radiate heat to the outside of the cabinet 200 through the wall of the heat dissipation pipe 121 and the rear panel 112 after entering the pipe 123. Compared with traditional cabinets, this effectively improves the heat radiation efficiency of the airflow in the internal circulating air duct 124, thereby improving the heat dissipation efficiency of the electronic equipment 210 inside the cabinet 200.

[0180] Example 3

[0181] Reference Figure 3 As shown in the illustration, this application also provides a cabinet assembly 10, including a cabinet 200 and at least one heat exchanger 100 as described in Embodiment 1. At least one heat exchanger 100 is disposed outside any side wall of the cabinet 200.

[0182] In one alternative implementation, the heat exchanger 100 is disposed on the outer wall of the cabinet 200, and the front side panel 111 of the heat exchanger 100 is attached to the outer surface of any side wall of the cabinet 200. The side wall of the cabinet 200 forms a cabinet air inlet and a cabinet air outlet. The cabinet air inlet and the cabinet air outlet are respectively connected to the inner air inlet 1111 and the inner air outlet 1112 on the front side panel 111. In this way, the hot airflow inside the cabinet 200 can enter the inner circulation duct 124 of the heat exchanger 100 through the cabinet air inlet and the inner air inlet 1111 of the front side panel 111 in sequence. After exchanging heat with the airflow in the outer circulation duct 125, it enters the interior of the cabinet 200 through the inner air outlet 1112 on the front side panel 111 and the cabinet air outlet.

[0183] Reference Figure 3 As shown, taking the installation method of the heat exchanger 100 on the rack 200 as an example, the heat dissipation process of the rack 200 in this embodiment of the application is as follows:

[0184] The hot airflow inside the rack 200, i.e., the internal circulating airflow a, enters the various internal circulating air ducts 124 of the heat exchanger 100 from the air inlet of the rack 200 and the internal air inlet 1111 on the front side panel 111. At the same time, the cold airflow outside the rack 200, i.e., the external circulating airflow b, enters the various external circulating air ducts 125 from the various external air inlets 1251 of the heat exchanger 100. On the one hand, the heat of the internal circulating airflow a in each internal circulating air duct 124 is first transferred to the external circulating air duct 125. In the external circulating airflow b inside 25, after being heated, the external circulating airflow b is discharged from the external air outlet 1252 of the external circulating air duct 125 to the outside of the cabinet 200, so that the heat of the electronic equipment 210 inside the cabinet 200 is discharged to the outside of the cabinet 200 through the external circulating airflow. After the internal circulating airflow a is cooled, it enters the inside of the cabinet 200 from the internal air outlet 1112 on the front side panel 111 and the cabinet air outlet, and blows towards the electronic equipment 210 to achieve heat dissipation of the electronic equipment 210.

[0185] On the other hand, the airflow in each internal circulation duct 124 radiates heat directly to the outside of the cabinet 200 through the rear side panel 112 in the form of thermal radiation, thereby achieving effective heat dissipation of the electronic equipment 210 inside the cabinet 200.

[0186] This embodiment of the application, by setting the heat exchanger 100 on the outside of any side wall of the cabinet 200, not only improves the heat dissipation efficiency of the electronic equipment 210 inside the cabinet 200, but also makes full use of the side space, waterproof cable routing space or wall-mounted mounting space outside the cabinet 200. This not only avoids occupying the internal space of the cabinet 200, but also reduces the size of the cabinet 200 while ensuring heat dissipation efficiency, making the heat exchanger 100 suitable for miniaturized outdoor cabinets.

[0187] In some examples, one side wall of the cabinet 200 can be configured as the front side panel 111 of the heat exchanger 100. For example, when assembling the cabinet 200, the heat dissipation tube array 120 of the heat exchanger 100 can be directly fixed to the rear side panel 112, left side panel 113, and right side panel 114 of the outer shell assembly 110. Then, one end of the left side panel 113 and the right side panel 114 can be fixed to the outside of one side wall of the cabinet 200. This saves one component of the heat exchanger 100, which simplifies the structure of the heat exchanger 100, improves the assembly efficiency of the cabinet 200, reduces the volume of the entire cabinet assembly 10, saves the space occupied by the cabinet assembly 10, and also reduces the weight of the cabinet assembly 10, making the installation of the cabinet assembly 10 more convenient.
