Description

Technical Field

[0001] The embodiments of the present application relate to the field of cooling technology, and in particular to a radiator. Background Art

[0002] At present, in the photovoltaic field, for example, in processes such as boron expansion and phosphorus expansion, the gas temperature inside or outside the high-temperature furnace is very high, and the suction device such as the fan that draws these high-temperature gases, and the pipeline that transmits these high-temperature gases are difficult to withstand high temperatures, for example, it is difficult to withstand temperatures above 1000°C. As a result, natural heat dissipation is basically used for cooling. There are problems such as a long time waiting for the gas to cool down to the required emission temperature and low cooling efficiency. Utility Model Content

[0003] In view of this, the present application provides a heat sink with improved heat dissipation efficiency.

[0004] The present application provides a radiator, which includes a shell and a heat dissipation component. The shell is provided with an air cavity, and the air cavity is for the gas to be cooled to pass through. The heat dissipation component is arranged in the air cavity. The shell is provided with a liquid cavity surrounding the outside of the air cavity. The radiator includes a first shell, a second shell and a plurality of condensers. The first shell is provided with a first cavity. The second shell is provided with a second cavity. The liquid cavity, the first cavity and the second cavity are respectively configured to accommodate cooling liquid. A plurality of condensers, each condenser is arranged between the first shell and the second shell, and is connected between the first cavity and the second cavity.

[0005] In the above-mentioned radiator, the first cavity, multiple condensation tubes and the second cavity form a cooling liquid circulation channel of the heat dissipation component. The liquid cavity is the circulation channel of the outer shell, and cooling liquid circulation channels are formed on the inner and outer sides of the air cavity at the same time, which increases the overall heat absorption of the radiator and thus improves the cooling efficiency of the radiator.

[0006] In a possible implementation, the heat dissipation assembly further includes a plurality of heat dissipation fins spaced apart in the air cavity, each heat dissipation fin being sleeved on the outside of at least one of the plurality of condensation tubes and spaced apart from the cavity wall of the air cavity at least in part.

[0007] In the above embodiment, the gas in the air cavity is filled between the multiple heat sinks, so that the multiple heat sinks fully absorb the heat of the gas in the air cavity. Each heat sink is sleeved on the outside of each of the multiple condensing tubes, and the multiple condensing tubes absorb the heat of each heat sink. The multiple condensing tubes arranged at intervals absorb the heat of one heat sink, which is conducive to neutralizing the different heat of the gas at different positions in the air cavity, and further improving the cooling efficiency.

[0008] In a possible implementation manner, the heat sink is configured to be made of copper sheet or stainless steel, and the thickness of the heat sink is less than or equal to 0.3 cm.

[0009] In the above embodiment, the copper sheet and the stainless steel have high thermal conductivity, which is conducive to improving the efficiency of the heat sink in transferring the heat of the gas to the condenser. The thickness of the heat sink is less than or equal to 0.3 cm. The thinner the thickness of the heat sink is, the faster the heat sink transfers the heat, thereby improving the efficiency of the heat sink in transferring the gas to the condenser.

[0010] In a possible implementation, the housing is provided with a first liquid inlet pipe and a first liquid outlet pipe communicating with the liquid cavity. One of the first shell and the second shell is provided with a second liquid inlet pipe, and the other is provided with a second liquid outlet pipe, one of the second liquid inlet pipe and the second liquid outlet pipe is connected to the first cavity, and the other is connected to the second cavity.

[0011] In the above embodiment, the first liquid inlet pipe and the first liquid outlet pipe, the second liquid inlet pipe and the second liquid inlet pipe form a first cooling liquid circulation channel in the liquid cavity of the shell. The second cooling liquid circulation channel is formed with the first cavity of the first shell, the second cavity of the second shell and the plurality of condensing pipes, and the two cooling liquid circulation channels are relatively independent. The first liquid inlet pipe and the second liquid inlet pipe are respectively fed with cooling liquid of lower temperature, which increases the cooling amount of the cooling liquid entering the radiator per unit time, thereby improving the efficiency of the cooling liquid in absorbing the heat of the gas.

[0012] In a possible embodiment, the housing is provided with an air inlet pipe and an air outlet pipe communicating with the air cavity. The second liquid inlet pipe is provided in the first housing, and the second liquid outlet pipe is provided in the second housing. The first liquid inlet pipe and the first liquid outlet pipe, the second liquid inlet pipe and the second liquid outlet pipe are arranged along the direction from the air inlet pipe to the air outlet pipe.

[0013] In the above embodiment, a coolant at a lower temperature enters the housing and the heat dissipation component while a gas at a higher temperature enters, effectively reducing the temperature of the gas before circulating in the air cavity. The coolant absorbs heat and its temperature is increased before being discharged from the first liquid outlet pipe and the second liquid outlet pipe, thereby improving the gas cooling efficiency and reducing the requirements for the heat resistance of the housing and the heat dissipation component.

[0014] In a possible embodiment, the direction in which the first shell, the condenser tube, and the second shell are sequentially arranged is the arrangement direction. The first liquid inlet pipe and the first liquid outlet pipe are respectively located at two opposite side walls of the shell along the arrangement direction. And / or the second liquid inlet pipe and the second liquid outlet pipe are respectively arranged at two opposite side walls of the first shell and the second shell along the arrangement direction.

[0015] In the above embodiment, the first liquid inlet pipe and the first liquid outlet pipe are arranged along the arrangement direction and arranged on both sides of the shell. The second liquid inlet pipe and the second liquid outlet pipe are arranged along the arrangement direction and arranged on both sides of the first shell and the second shell, which is conducive to reducing the cross-sectional size of the shell perpendicular to the arrangement direction, and further conducive to reducing the size of the entire radiator perpendicular to the arrangement direction.

[0016] In a possible implementation, along the vertical direction, the first liquid inlet pipe is located below the first liquid outlet pipe, and the second liquid inlet pipe is located below the second liquid outlet pipe.

[0017] In the above embodiment, the coolant tends to move upward when heated, and arranging the liquid outlet pipe above the liquid inlet pipe in the vertical direction is beneficial to speed up the outflow of the coolant from the liquid outlet pipe, thereby helping to improve the heat dissipation efficiency and the cooling efficiency of the air cavity.

[0018] In a possible implementation, the housing is provided with two through holes, one of the two through holes is configured to allow the second liquid inlet pipe to pass through and is sealed to the outer wall of the second liquid inlet pipe, and the other of the two through holes is configured to allow the second liquid outlet pipe to pass through and is sealed to the outer wall of the second liquid outlet pipe.

[0019] In the above embodiment, the two through holes allow coolant to flow into the shell and the heat dissipation component respectively, and the two through holes are sealed with the second liquid inlet pipe and the second liquid outlet pipe respectively, effectively ensuring the sealing of the air cavity and reducing or avoiding the risk of high-temperature gas leaking out of the radiator.

[0020] In a possible embodiment, the first shell and the second shell are respectively spaced apart from at least a portion of the cavity wall of the air cavity, and the radiator also includes a partition plate, which is sleeved on the outer side of each of the multiple condensation tubes, and the partition plate is spaced apart from at least a portion of the cavity wall of the air cavity to form a gas flow channel with a curved path in the air cavity.

[0021] In the above embodiment, the partition plate forms a curved gas flow channel in the air cavity, which increases the path length of the air flow and further improves the cooling efficiency.

[0022] In a possible implementation, the first shell and the second shell are spaced apart from the upper cavity wall or the lower cavity wall of the air cavity along the vertical direction, respectively. One of the two adjacent partition plates is spaced apart from the upper cavity wall of the air cavity along the vertical direction, and the other of the two adjacent partition plates is spaced apart from the lower cavity wall of the air cavity along the vertical direction.

[0023] In the above embodiment, the gas is heated to facilitate upward movement, and the up and down reciprocating curved path is conducive to increasing the flow velocity of the gas. Increasing the flow velocity of the gas while increasing the length of the gas flow path helps to coordinate the cooling capacity utilization and cooling efficiency.

[0064] In order to further illustrate the technical means and effects adopted by the present application to achieve the intended application purpose, the following is combined with the drawings and implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0066] Some embodiments of the present application provide a radiator, which includes a housing and a heat dissipation component. The housing is provided with an air cavity for the gas to be cooled to pass through. The heat dissipation component is arranged in the air cavity. The housing is provided with a liquid cavity surrounding the outside of the air cavity. The radiator includes a first shell, a second shell and a plurality of condensers.

The liquid cavity, the first cavity and the second cavity are respectively configured to accommodate a coolant. A plurality of condensers, each condenser is arranged between the first shell and the second shell, and is connected between the first cavity and the second cavity.

[0067] In the above-mentioned radiator, the first cavity, multiple condensation tubes and the second cavity form a cooling liquid circulation channel of the heat dissipation component. The liquid cavity is the circulation channel of the outer shell, and cooling liquid circulation channels are formed on the inner and outer sides of the air cavity at the same time, which increases the overall heat absorption of the radiator and thus improves the cooling efficiency of the radiator.

[0068] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0069] Please also see Figures 1 to 3 One embodiment of the present application provides a radiator 100. The radiator 100 is used to cool high-temperature gas. For example, the radiator 100 is connected to an exhaust pipe of a high-temperature furnace, or other equipment that needs to discharge high-temperature gas, so as to cool the high-temperature gas to a required temperature that can be discharged into the outside air.

[0070] The heat sink 100 includes a housing 10 and a heat dissipation assembly 20. The heat dissipation assembly 20 is disposed in the housing 10. The housing 10 and the heat dissipation assembly 20 respectively use liquid cooling to cool the gas.

[0071] The housing 10 is provided with an air cavity 101 and a liquid cavity 102 surrounding the outer periphery of the air cavity 101. The air cavity 101 is for the gas to be cooled to pass through. The liquid cavity 102 is used to circulate the cooling liquid, which may also be water or other liquids. The heat dissipation assembly 20 is located in the air cavity 101 to cool the gas in the air cavity 101. The heat dissipation assembly 20 includes a first shell 21, a second shell 22 and a plurality of condensing tubes 23. The first shell 21 is provided with a first cavity 2101, and the second shell 22 is provided with a second cavity 2201. The first shell 21 and the second shell 22 are arranged in the air cavity 101 at intervals. A plurality of condensing tubes 23 are arranged between the first shell 21 and the second shell 22, and each condensing tube 23 is connected between the first cavity 2101 and the second cavity 2201, so that the cooling liquid of the plurality of condensing tubes 23 converges in the first cavity 2101 or the second cavity 2201.

[0072] The first cavity 2101, multiple condensing tubes 23 and the second cavity 2201 form a cooling liquid circulation channel for the heat dissipation component 20. The liquid cavity 102 is a circulation channel for the outer shell 10. Cooling liquid circulation channels are formed on the inner and outer sides of the air cavity 101 at the same time, which increases the overall heat absorption of the radiator 100 and thereby improves the cooling efficiency of the radiator 100.

[0073] See also Figure 1 and Figure 2 In one embodiment, the shell 10 is a roughly rectangular double-layer shell structure, but is not limited thereto. For example, in another embodiment, the shell 10 may also be an elliptical shell structure, a special-shaped shell structure with a spherical top, etc. The present application does not limit the shape of the shell 10.

[0074] For the convenience of subsequent description, the direction in which the first shell 21 , the plurality of condensing tubes 23 , and the second shell 22 are sequentially arranged is defined as an arrangement direction X.

[0075] The housing 10 includes a main body 11, an air inlet pipe 12 and an air outlet pipe 13. The air cavity 101 is provided in the main body 11. The main body 11 includes a first side wall 111 and a second side wall 112 arranged opposite to each other, a third side wall 115 and a fourth side wall 116 arranged opposite to each other, and a top wall 113 and a bottom wall 114. The top wall 113 is connected to the top of the first side wall 111, the second side wall 112, the third side wall 115 and the fourth side wall 116, and the bottom wall 114 is connected to the bottom of the first side wall 111, the second side wall 112, the third side wall 115 and the fourth side wall 116. The third side wall 115 is connected to one side of the first side wall 111 and the second side wall 112, and the fourth side wall 116 is connected to the other side of the first side wall 111 and the second side wall 112. The first side wall 111 , the second side wall 112 , the third side wall 115 , the fourth side wall 116 , the top wall 113 and the bottom wall 114 are arranged to form the air cavity 101 .

[0076] In one embodiment, the first side wall 111, the second side wall 112, the third side wall 115, the fourth side wall 116, the top wall 113 and the bottom wall 114 are double-wall structures, and are connected to the inner wall close to the air cavity 101 and the outer wall away from the air cavity 101, that is, the inner and outer walls are used for circulating cooling liquid.

[0077] In one embodiment, the air inlet pipe 12 is disposed on the side of the first side wall 111 away from the air cavity 101. The air outlet pipe 13 is disposed on the side of the second side wall 112 away from the air cavity 101. The air inlet pipe 12 and the air outlet pipe 13 respectively include an inner pipe wall and an outer pipe wall surrounding the inner pipe wall, and the inner and outer pipe walls are used to circulate the cooling liquid. The inner and outer pipe walls of the air inlet pipe 12 and the air outlet pipe 13 are connected to the inner and outer side walls of the main body 11, thereby forming a liquid cavity 102 located between the double walls (inner and outer side walls, inner and outer pipe walls), but it is not limited thereto.

[0078] It can be understood that in other embodiments, the bottom wall 114 is a single-layer wall, the coolant will not flow through the bottom wall 114, and the bottom wall 114 is placed on a platform (for example, the ground, not shown) to absorb heat from the gas in the air cavity 101 through heat conduction through the contact between the bottom wall 114 and the platform.

[0079] It can be understood that in other embodiments, the air inlet pipe 12 and the air outlet pipe 13 can also be formed on the main body 11. For example, the first side wall 111 and the second side wall 112 of the main body 11 respectively have openings (not shown), and the air inlet pipe 12 and the air outlet pipe 13 are respectively formed at the openings.

[0080] Please continue reading Figure 2 , Figure 3 and Figure 4 In one embodiment, the housing 10 is provided with a first liquid inlet pipe 16 and a first liquid outlet pipe 17 connected to the liquid cavity 102. The first housing 21 is provided with a second liquid inlet pipe 211. The second housing 22 is provided with a second liquid outlet pipe 221. The second liquid inlet pipe 211 is connected to the first cavity 2101. The second liquid outlet pipe 221 is connected to the second cavity 2201.

[0081] The first liquid inlet pipe 16 and the first liquid outlet pipe 17, the second liquid inlet pipe 211 and the second liquid outlet pipe 221, form a first cooling liquid circulation channel in the liquid cavity 102 of the shell 10; and form a second cooling liquid circulation channel together with the first cavity 2101 of the first shell 21, the second cavity 2201 of the second shell and the plurality of condensing tubes 23, and the two cooling liquid circulation channels are relatively independent, and the first liquid inlet pipe 16 and the second liquid inlet pipe 211 respectively introduce coolant with lower temperature, thereby increasing the cooling amount of the coolant entering the radiator 100 per unit time, thereby improving the efficiency of the coolant absorbing the heat of the gas.

[0082] In one embodiment, the first liquid inlet pipe 16 and the first liquid outlet pipe 17 are arranged along the direction of the air inlet pipe 12 toward the air outlet pipe 13. The second liquid inlet pipe 211 and the second liquid outlet pipe 221 are arranged along the direction of the air inlet pipe 12 toward the air outlet pipe 13. The direction of the first side wall 111 toward the second side wall 112 is parallel to the arrangement direction X. The first shell 21 faces the first side wall 111, and the second shell 22 faces the second side wall 112. That is, the air inlet pipe 12 is close to the first liquid inlet pipe 16 and the second liquid inlet pipe 211, and the air outlet pipe 13 is close to the first liquid outlet pipe 17 and the second liquid outlet pipe 221.

[0083] A coolant at a lower temperature enters the housing 10 and the heat dissipation component 20, and a gas at a higher temperature enters at the same time, which effectively reduces the temperature of the gas and then circulates in the air cavity 101. The coolant absorbs heat and its temperature is increased and then discharged from the first liquid outlet pipe 17 and the second liquid outlet pipe 221, thereby improving the gas cooling efficiency and reducing the requirements for the heat resistance of the housing 10 and the heat dissipation component 20.

[0084] In one embodiment, the housing 10 further includes a first connection flange 14 and a second connection flange 15. The first connection flange 14 is disposed on the periphery of the air inlet pipe 12 and is used to connect to a device that discharges gas (e.g., a high-temperature furnace, not shown). The second connection flange 15 is disposed on the periphery of the air outlet pipe 13 and is used to connect to a device that draws gas (e.g., an exhaust fan, not shown).

[0085] In one embodiment, the housing 10 has two through holes 103, one of the two through holes 103 is configured to allow the second liquid inlet pipe 211 to pass through and is sealed and connected to the outer wall of the second liquid inlet pipe 211; the other of the two through holes 103 is configured to allow the second liquid outlet pipe 221 to pass through and is sealed and connected to the outer wall of the second liquid outlet pipe 221.

[0086] The two through holes 103 allow coolant to flow into the housing 10 and the heat dissipation assembly 20 respectively, and the two through holes 103 are sealedly connected to the second liquid inlet pipe 211 and the second liquid outlet pipe 221 respectively, effectively ensuring the sealing of the air cavity 101 and reducing or avoiding the risk of high-temperature gas leaking out of the radiator 100.

[0087] It can be understood that in other embodiments, the two through holes 103, the second liquid inlet pipe 211 and the second liquid outlet pipe 221 can also be omitted. One of the first cavity 2101 and the second cavity 2201 of the first shell 21 can also be communicated with the first liquid inlet pipe 16, and the other can be communicated with the second liquid outlet pipe 221. The shell 10 does not need to be provided with the through hole 103 for the second liquid inlet pipe 211 and the second liquid outlet pipe 221 to pass through, thereby simplifying the process of the shell 10 and improving the sealing performance of the shell 10.

[0088] The first liquid inlet pipe 16 and the first liquid outlet pipe 17 are arranged along the arrangement direction X and are arranged on both sides of the shell 10; the second liquid inlet pipe 211 and the second liquid outlet pipe 221 are arranged along the arrangement direction X and are arranged on both sides of the first shell 21 and the second shell 22, which is beneficial to reducing the cross-sectional size of the shell 10 perpendicular to the arrangement direction X, and further beneficial to reducing the overall size of the radiator 100 perpendicular to the arrangement direction X.

[0089] In addition, the first liquid inlet pipe 16, the second liquid inlet pipe 211, the air inlet pipe 12, the second liquid outlet pipe 221, the second liquid outlet pipe 221 and the air outlet pipe 13 are respectively concentrated on both sides of the shell 10, which is convenient for connecting, installing and repairing the pipes.

[0090] It can be understood that in other embodiments, the first liquid inlet pipe 16 and / or the first liquid outlet pipe 17 can also be arranged on the third side wall 115, the fourth side wall 116, the top wall 113 or the bottom wall 114, etc.

[0091] It can be understood that in other embodiments, the arrangement direction X of the first liquid inlet pipe 16 and the first liquid outlet pipe 17 and the arrangement direction X of the second liquid inlet pipe 211 and the second liquid outlet pipe 221 may also be opposite.

[0092] In one embodiment, if Figure 1 and Figure 3 As shown, the first liquid inlet pipe 16 is located below the first liquid outlet pipe 17 along the vertical direction Y, and the second liquid inlet pipe 211 is located below the second liquid outlet pipe 221 along the vertical direction Y. The coolant tends to move upward when heated, and arranging the outlet pipe above the liquid inlet pipe along the vertical direction Y is conducive to accelerating the outflow of the coolant, thereby facilitating the heat dissipation efficiency and the cooling efficiency of the air cavity 101.

[0093] In one embodiment, the first liquid outlet pipe 17 is connected between the double-layer side walls of the top wall 113, and the first liquid inlet pipe 16 is connected between the double-layer side walls of the bottom wall 114, thereby facilitating the cooling liquid in the bottom wall 114 to move upward when heated, and the device is discharged from the first liquid outlet pipe 17 at the top wall 113.

[0094] It can be understood that the first liquid inlet pipe 16 can also be located above the first liquid outlet pipe 17, and / or the second liquid inlet pipe 211 can be located above the second liquid outlet pipe 221, so as to improve the cooling capacity utilization rate of the coolant by reducing the coolant flow rate and extending the heat absorption time.

[0095] See also Figure 3 and Figure 5 In one embodiment, the heat dissipation assembly 20 further includes a plurality of heat sinks 24. The plurality of heat sinks 24 are located in the air cavity 101 and are arranged at intervals. The heat sinks 24 are arranged at intervals from the cavity wall of the air cavity 101. The gas in the air cavity 101 is filled between the plurality of heat sinks 24, so that the plurality of heat sinks 24 fully absorb the heat of the gas in the air cavity 101. Each heat sink 24 is sleeved on the outside of each of the plurality of condensing tubes 23. Each heat sink 24 is in contact with the plurality of condensing tubes 23, so that the plurality of condensing tubes 23 absorb the heat of each heat sink 24. The plurality of condensing tubes 23 arranged at intervals absorb the heat of one heat sink 24, which is conducive to neutralizing the different heat of the gas at different positions in the air cavity 101, and further improving the cooling efficiency.

[0096] In one embodiment, the heat sink 24 and the condenser tube 23 are closely matched, but not limited thereto. For example, in another embodiment, the heat sink 24 and the condenser tube 23 can also be welded together.

[0097] In one embodiment, the heat sink 24 is configured to be made of copper. The copper has a high thermal conductivity, which is conducive to the heat sink 24 transferring the heat of the gas to the condenser 23. It is understood that in other embodiments, the heat sink 24 can also be made of other materials with high thermal conductivity, such as stainless steel.

[0098] In one embodiment, the thickness of the heat sink 24 is less than or equal to 0.3 cm. The thinner the thickness of the heat sink 24 is, the faster the heat sink 24 conducts heat, thereby improving the efficiency of the heat sink 24 conducting gas to the condenser 23 .

[0099] It is understandable that in other embodiments, the heat sink 24 may also be in contact with a portion of the cavity wall of the air cavity 101 , so that the heat absorbed by the heat sink 24 is transferred to the coolant in the liquid cavity 102 .

[0100] Please continue reading Figure 3 , Figure 6 and Figure 7In one embodiment, the heat sink 100 further includes a partition plate 30. The partition plate 30 is sleeved on the outer sides of the plurality of condensing tubes 23, and the partition plate 30 and the condensing tubes 23 are roughly sealed by a tight fit or welding. The first shell 21 and the second shell 22 are respectively spaced apart from at least a portion of the cavity wall of the air cavity 101, and the partition plate 30 is spaced apart from at least a portion of the cavity wall of the air cavity 101, so that the gas in the air cavity 101 can pass between the cavity wall of the air cavity 101 and the partition plate 30, so as to form a curved air flow channel in the air cavity 101.

[0101] The number of the partition plates 30 is two, but not limited thereto. Two adjacent partition plates 30 are attached to different parts of the cavity wall of the air cavity 101 to form a curved gas flow channel in the air cavity 101 .

[0102] It is understandable that in other embodiments, the number of partition plates 30 may also be three, four, or other numbers, thereby further increasing the path length of the airflow and further improving the cooling efficiency.

[0103] When the heat dissipation assembly 20 and the partition plate 30 are installed, the partition plate 30 is inserted between multiple heat sinks 24, and the partition plate 30 and the heat sink 24 are installed together on the outside of the condenser 23, and then the condenser 23 is connected to the first shell 21 or the second shell 22.

[0104] One of the two adjacent partition plates 30 has a distance from the upper cavity wall of the air cavity 101 along the vertical direction Y, and the other of the two adjacent partition plates 30 has a distance from the lower cavity wall of the air cavity 101 along the vertical direction Y.

[0105] Figure 7 The diagram shows that the first shell 21, the second shell 22, and the two partition plates 30 are installed in the air cavity 101 when the top wall 113 is removed, wherein the first shell 21 contacts the inner side walls of the bottom wall 114, the third side wall 115, and the fourth side wall 116, that is, there is a gap between the first shell 21 and the inner side wall of the top wall 113; the partition plate 30 adjacent to the first shell 21 contacts the inner side walls of the top wall 113, the third side wall 115, and the fourth side wall 116, that is, the partition adjacent to the first shell 21 contacts the inner side walls of the top wall 113, the third side wall 115, and the fourth side wall 116, that is, the partition adjacent to the first shell 21 contacts the inner side walls of the bottom wall 114, the third side wall 115, and the fourth side wall 116, 14 has a spacing between the inner walls; the partition plate 30 adjacent to the second shell 22 is in contact with the inner walls of the bottom wall 114, the third side wall 115 and the fourth side wall 116, that is, there is a spacing between the partition plate 30 adjacent to the second shell 22 and the inner wall of the top wall 113; the second shell 22 is in contact with the inner walls of the top wall 113, the third side wall 115 and the fourth side wall 116, that is, there is a spacing between the second shell 22 and the inner wall of the bottom wall 114, so that the airflow flows along a reciprocating curved path, such as Figure 8The arrows in the figure indicate the path of gas flow. The inner side wall of the top wall 113 of the main body 11 is the upper cavity wall of the air cavity 101 along the vertical direction Y, and the inner side wall of the bottom wall 114 of the main body 11 is the lower cavity wall of the air cavity 101 along the vertical direction Y.

[0106] When heated, the gas tends to move upward, and the up and down curved path is conducive to increasing the flow velocity of the gas. Increasing the flow velocity of the gas while increasing the length of the gas flow path helps to coordinate the cooling capacity utilization and cooling efficiency.

[0107] It is understandable that in other embodiments, a curved gas flow path may be formed by providing a gap between the first shell 21 , the second shell 22 , and the plurality of partition plates 30 and the third side wall 115 or the fourth side wall 116 .

[0108] In the above-mentioned radiator 100, the first cavity 2101, multiple condensation tubes 23 and the second cavity 2201 form a cooling liquid circulation channel for the heat dissipation component 20, the liquid cavity 102 is the circulation channel of the outer shell 10, and cooling liquid circulation channels are formed on the inner and outer sides of the air cavity 101 at the same time, which increases the overall heat absorption of the radiator 100 and thereby improves the cooling efficiency of the radiator 100.

[0109] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
