Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioner technology, and more specifically, to a support assembly, a condenser, and an air conditioner. Background Technology
[0002] In related technologies, high-temperature refrigerant vapor needs to enter the condenser for heat exchange. This causes condensation to continuously form on the outer wall of the heat exchange tubes inside the condenser, and the condensate flows downwards to continue heat exchange. However, the continuously flowing condensate forms a liquid film on the bottom heat exchange tubes. Over time, this film thickens, creating a significant thermal resistance on the outer wall of the heat exchange tubes. This gradually blocks the contact between the outer wall of the heat exchange tubes and the refrigerant vapor, preventing the heat exchange tubes in the condenser from performing optimally. Furthermore, as the number of heat exchange tube rows increases, the condensation efficiency decreases towards the bottom of the tubes, leading to a reduction in the overall heat exchange efficiency of the condenser. Summary of the Invention
[0003] This application provides a support assembly, condenser, and air conditioner to solve or improve the technical problem that refrigerant droplets accumulate on the lower heat exchange tube to form a liquid film, resulting in a large thermal resistance on the outer wall of the heat exchange tube, thereby reducing the heat exchange efficiency of the condenser.
[0004] An embodiment of this application provides a support assembly for a condenser. The support assembly includes a plurality of first fixing plates and at least one guide plate. The plurality of first fixing plates are spaced apart and are used to fix heat exchange tubes passing through the plurality of first fixing plates. The guide plate passes through the plurality of first fixing plates, and the at least one guide plate divides the first fixing plates into a first guiding region and a second guiding region. The guide plate is configured to guide condensate on the heat exchange tubes in the first guiding region to the outside of the heat exchange tubes in the second guiding region.
[0005] Thus, by setting a guide plate on the support assembly and making the fluid flow guided by the guide plate intersect with the air flow, the condensate formed after the heat exchange tube exchanges heat with the gas can drip onto the support plate under the guidance of the guide plate. This prevents the condensate from accumulating on the heat exchange tube near the bottom of the first fixed plate to form a liquid film, and allows the outer wall of the heat exchange tube to fully contact the refrigerant vapor, thereby improving the heat exchange efficiency of the condenser.
[0006] In some embodiments, the direction of the condensate flow guided by the baffle plate intersects with the direction of the refrigerant gas flow.
[0007] In this way, by intersecting the direction of the condensate flow guided by the baffle plate with the direction of the refrigerant flow, the condensate in the area can be quickly guided out of the guiding area along the baffle plate, thus avoiding the continuous accumulation of condensate on the bottom heat exchange tube and affecting heat exchange.
[0008] In some embodiments, the first fixing plate includes a plurality of first fixing hole units, each of which includes three first fixing holes. The first fixing holes are used to fix the heat exchange tube. The three first fixing holes are arranged in an equilateral triangle along the refrigerant gas flow direction. The direction of the condensate flow guided by the guide plate is approximately parallel to one of the sides of the equilateral triangle.
[0009] Thus, by arranging the first fixing hole unit in an equilateral triangle, and with the direction of the condensate flow guided by the baffle plate being approximately parallel to one of the sides of the equilateral triangle, the number of heat exchange tubes can be reduced without affecting the heat exchange efficiency, thereby lowering costs.
[0010] In some embodiments, the support assembly includes a superheated heat exchange zone, a two-phase condensing heat exchange zone, and a subcooled heat exchange zone, wherein the superheated heat exchange zone, the two-phase condensing heat exchange zone, and the subcooled heat exchange zone are arranged sequentially along the refrigerant gas flow direction, and the guide plate is disposed in the two-phase condensing heat exchange zone.
[0011] Thus, since the main function of the superheated heat exchange zone is to cool the refrigerant gas to a saturated state without forming condensate, and the subcooled heat exchange zone is to exchange heat with the saturated state of the condensate, the arrangement area of the guide plate can be reduced by placing the guide plate in the two-phase condensation heat exchange zone, thereby reducing the cost.
[0012] In some embodiments, the outer wall of the heat exchange tube is provided with fins, and the density of the fins in the two-phase condensation heat exchange zone is greater than the density of the fins in the superheated heat exchange zone and the subcooled heat exchange zone.
[0013] In this way, by making the fin density of the heat exchange tubes in the two-phase condensation heat exchange zone greater than that in the superheated heat exchange zone, the corresponding heat exchange tubes can be arranged according to different regions, thereby reducing the cost required to manufacture the heat exchange tubes.
[0014] In some embodiments, the support assembly includes a support plate, and the first fixing plate includes a boss. The first fixing plate and the support plate are connected through the boss so that the first fixing plate and the support plate are spaced apart and form a liquid guiding channel.
[0015] In this way, by connecting the boss on the first fixed plate to the support plate to form a liquid guiding channel, the condensate can be prevented from being blocked by the first fixed plate.
[0016] In some embodiments, a flow guiding space is formed between the surface of the support plate away from the first fixed plate and the inner wall of the condenser shell, and a connecting channel is formed between each end of the support plate and the inner wall of the condenser shell, the connecting channel connecting the flow guiding space and the liquid guiding channel, so that the condensed liquid enters the flow guiding space.
[0017] Thus, by providing connecting channels at both ends of the support plate, the connecting channels connect the flow space and the liquid channel formed between the support plate and the shell, allowing the condensed liquid to flow from the liquid channel into the flow space for heat exchange, thereby further improving the heat exchange efficiency of the condenser.
[0018] In some embodiments, the support plate is connected to a plurality of second fixing plates on the surface opposite to the first fixing plate. The plurality of second fixing plates are staggered on the inner wall of the flow guiding space. Each second fixing plate is provided with a plurality of second fixing hole units, each second fixing hole unit including three second fixing holes. The three second fixing holes are arranged in a triangular shape along the flow direction of the condensate. The second fixing holes are used to fix the heat exchange tube that passes through the plurality of second fixing plates.
[0019] Thus, by setting a second fixing plate within the flow guiding space, heat exchange tubes can be fixed within the flow guiding space for heat exchange, thereby improving heat exchange efficiency. Furthermore, the triangular arrangement of the heat exchange tubes allows the condensate to form laminar flow, resulting in low flow resistance and accelerating the discharge of the condensate.
[0020] A condenser according to an embodiment of this application includes a heat exchange tube and a support assembly as described in any of the above embodiments, wherein the heat exchange tube is connected to the support assembly.
[0021] In some embodiments, the condenser includes a shell and a gas equalization assembly. The shell is provided with an air inlet, a liquid outlet, and a receiving cavity. The air inlet and the liquid outlet are disposed opposite to each other on the side wall of the shell, and the air inlet communicates with the receiving cavity. The liquid outlet communicates with the flow guiding space. The gas equalization assembly is connected to the top wall of the shell and covers the air inlet. The gas equalization assembly is spaced apart from the heat exchange tube. The support plate is connected to the bottom wall of the shell and covers the liquid outlet.
[0022] Thus, by providing an air inlet and a liquid outlet on the casing, high-temperature refrigerant gas can enter the containment cavity for heat exchange, and the condensate formed after heat exchange can be discharged from the containment cavity through the liquid outlet, thereby achieving the condensation process of the refrigerant gas. By providing a gas distribution component to cover the air inlet, the refrigerant gas flow entering from the air inlet can be blocked, reducing the flow velocity of the refrigerant gas and preventing damage caused by the refrigerant gas directly impacting the heat exchange tubes.
[0023] In some embodiments, the air equalization component includes an air equalization hole, which is located outside the projection of the air inlet on the air equalization component.
[0024] Thus, by setting gas equalization holes on the gas equalization component, the refrigerant gas entering from the air inlet can be uniformly fed into the containment cavity.
[0025] In some embodiments, the air distribution holes are provided corresponding to the first flow guiding region and the second flow guiding region.
[0026] Thus, by setting the gas equalization holes correspondingly in the first and second flow guiding regions, the refrigerant gas can be uniformly introduced into the first and second flow guiding regions, thereby improving the heat exchange efficiency of the condenser.
[0027] An air conditioner according to an embodiment of this application includes the support assembly or the condenser described in any of the above embodiments.

[0045] Please see Figure 1 , Figure 2 and Figure 3 According to an embodiment of this application, a support assembly 10 is used in a condenser 100. The support assembly 10 includes a plurality of first fixing plates 11 and at least one guide plate 12. The plurality of first fixing plates 11 are spaced apart and are used to fix heat exchange tubes 20 passing through the plurality of first fixing plates 11. The guide plate 12 passes through the plurality of first fixing plates 11, and at least one guide plate 12 divides the first fixing plates 11 into a first guide region 112 and a second guide region 113. The guide plate 12 is configured to guide the condensed liquid on the heat exchange tubes 20 in the first guide region 112 to the outside of the heat exchange tubes 20 in the second guide region 113.
[0046] Thus, by setting a guide plate 12 on the support assembly 10, and making the fluid flow direction guided by the guide plate 12 intersect with the air flow direction, the condensate formed after the heat exchange tube 20 exchanges heat with the gas can drip onto the support plate 16 under the guidance of the guide plate 12. This prevents the condensate from accumulating on the heat exchange tube 20 near the bottom of the first fixed plate 11 to form a liquid film, and allows the outer wall of the heat exchange tube 20 to fully contact the refrigerant vapor, thereby improving the heat exchange efficiency of the condenser 100.
[0047] The air conditioner 1000 (not shown in the attached diagram) includes a condenser 100, which is a device that uses a liquid as a heat transfer medium to exchange heat with a high-temperature refrigerant gas, turning the high-temperature refrigerant gas into a low-temperature refrigerant liquid. The condenser 100 includes a support assembly 10 and heat exchange tubes 20. The support assembly 10 is used to fix the heat exchange tubes 20, thereby preventing the heat exchange tubes 20 from moving when the refrigerant gas enters the condenser 100 for heat exchange, thus affecting the heat exchange efficiency.
[0048] Specifically, the support assembly 10 includes a first fixing plate 11 and a guide plate 12. There can be multiple first fixing plates 11. For example, there can be four, five, or six first fixing plates 11. Multiple first fixing plates 11 are fixedly connected to the side wall of the condenser 100, and can be fixed together by connecting rods 116. The multiple first fixing plates 11 are spaced apart, and their surfaces are arranged parallel to each other, allowing the heat exchange tube 20 to pass through and be fixed by the multiple first fixing plates 11. This distributes the stress on the heat exchange tube 20 onto the first fixing plates 11, preventing the heat exchange tube 20 from moving while also preventing the first fixing plates 11 from being damaged by excessive stress.
[0049] In some embodiments, the first fixed plate 11 is provided with vent holes 111 for balancing the pressure and airflow on both sides of the first fixed plate 11. Since there is a heat exchange temperature difference along the length of the condenser 100 when the condenser 100 is long, the vent holes 111 can allow airflow to flow axially according to the heat exchange requirements of different areas, avoiding excessive airflow resistance and poor local heat exchange.
[0050] The guide plate 12 guides the flow of the condensate formed after the refrigerant gas undergoes heat exchange. There can be one or more guide plates 12, which can pass through the first fixing plate 11, thus fixing one or more guide plates 12 to the first fixing plate 11. Furthermore, there needs to be a gap between the guide plate 12 and the housing 30 of the condenser 100 to guide the condensate to flow from the gap to the liquid outlet 32. When there is only one guide plate 12, the guide plate 12 can divide the first fixed plate 11 into a first guide region 112 and a second guide region 113, and the first guide region 112 and the second guide region 113 are separated by the guide plate 12. Thus, the guide plate 12 can guide the condensate formed on the heat exchange tube 20 of the refrigerant gas in the first guide region 112 to the outside of the heat exchange tube 20 in the second guide region 113, thereby preventing the condensate in the first guide region 112 from flowing into the second guide region 113 and preventing the accumulation of liquid film on the bottom heat exchange tube 20 of the second guide region 113, which would reduce the heat exchange efficiency of the bottom heat exchange tube 20. For example, the condensate formed on the heat exchange tube 20 in the first flow guiding region 112 can fall onto the guide plate 12 under the action of gravity and the blowing of the refrigerant gas flow. Since the guide plate 12 separates the first flow guiding region 112 and the second flow guiding region 113, the condensate in the first flow guiding region 112 can be guided by the guide plate 12 into the gap between the shell 30 of the condenser 100 and the guide plate 12, and flow into the liquid outlet 32 through the gap, thereby preventing the condensate from entering the second flow guiding region 113.
[0051] When there are multiple guide plates 12, the multiple guide plates 12 can divide the first fixed plate 11 into multiple guide regions. The multiple guide regions can be separated by the guide plates 12 so that the condensate formed by the refrigerant gas in the multiple guide regions falls onto different guide plates 12 for guidance. This can prevent the condensate from falling from the upper guide region into the lower guide region in sequence, which would cause the heat exchange tube 20 of the last guide region to accumulate and form a liquid film, reducing the heat exchange efficiency of the bottom heat exchange tube 20.
[0052] Please see Figure 2 In some embodiments, the direction of the condensate flow guided by the deflector 12 intersects with the direction of the refrigerant gas flow.
[0053] In this way, by intersecting the direction of the condensate flow guided by the guide plate 12 with the direction of the refrigerant flow, the condensate in the area can be quickly guided out of the guiding area along the guide plate 12, thus avoiding the continuous accumulation of condensate on the bottom heat exchange tube 20 and affecting heat exchange.
[0054] Specifically, the guide plate 12 can be inclinedly installed on the first fixed plate 11 so that the flow direction of the condensate guided by the guide plate 12 intersects with the flow direction of the refrigerant gas. For example, the refrigerant gas can flow into the condenser 100 for heat exchange along the direction of gravity, so that the condensate formed on the heat exchange tube 20 can move with the flow direction of the refrigerant gas, thereby detaching from the surface of the heat exchange tube 20 more quickly and reducing the residence time of the condensate. At the same time, when the refrigerant gas blows the surface of the heat exchange tube 20, since the gas velocity is much higher than the condensate velocity, the refrigerant gas has an impact effect on the condensate, which can reduce the aggregation and agglomeration of the condensate, keeping the condensate in a more dispersed and uniform distribution state, which is conducive to the condensate flowing away along the surface of the heat exchange tube 20. When the condensate falls on the guide plate 12, the inclined guide plate 12 can make the condensate flow out of the guide area quickly, avoiding the accumulation of condensate in the guide area.
[0055] Please see Figure 2 In some embodiments, the first fixing plate 11 includes a plurality of first fixing hole units 114, and the first fixing hole unit 114 includes three first fixing holes 1141. The first fixing holes 1141 are used to fix the heat exchange tube 20. The three first fixing holes 1141 are arranged in an equilateral triangle along the refrigerant gas flow direction. The condensate flow direction guided by the guide plate 12 is approximately parallel to one of the waists of the equilateral triangle.
[0056] Thus, by arranging the first fixing hole unit 114 in an equilateral triangle and ensuring that the direction of the condensate flow guided by the guide plate 12 is approximately parallel to one of the sides of the equilateral triangle, the number of heat exchange tubes 20 can be reduced without affecting the heat exchange efficiency, thereby lowering the cost.
[0057] Specifically, the first fixing plate 11 includes a first fixing hole unit 114, which can be used to fix the heat exchange tubes 20 and arrange the heat exchange tubes 20 according to the first fixing hole unit 114. There can be multiple first fixing hole units 114, which can fix multiple heat exchange tubes 20 to improve the heat exchange efficiency of the condenser 100. The first fixing hole unit 114 includes three first fixing holes 1141, which can be arranged in an equilateral triangle along the refrigerant gas flow direction, that is, the three heat exchange tubes 20 can be arranged in an equilateral triangle along the direction of gravity, thereby allowing the condensate formed on the heat exchange tubes 20 to move along the refrigerant gas flow direction.
[0058] Furthermore, the direction of the condensate flow guided by the inclined guide plate 12 is roughly parallel to one of the sides of the equilateral triangle, thereby saving the number of heat exchange tubes 20 and reducing the cost required to arrange the heat exchange tubes 20 while ensuring the heat exchange area of the heat exchange tubes 20.
[0059] Please see Figure 2 In some embodiments, the support assembly 10 includes a superheated heat exchange zone 13, a two-phase condensing heat exchange zone 14, and a subcooled heat exchange zone 15. The superheated heat exchange zone 13, the two-phase condensing heat exchange zone 14, and the subcooled heat exchange zone 15 are arranged sequentially along the refrigerant gas flow direction, and the guide plate 12 is arranged in the two-phase condensing heat exchange zone 14.
[0060] Thus, since the main function of the superheated heat exchange zone 13 is to cool the refrigerant gas to a saturated state and no condensate is formed, while the subcooled heat exchange zone 15 is for heat exchange of the saturated state of the condensate, by placing the guide plate 12 in the two-phase condensation heat exchange zone 14, the arrangement area of the guide plate 12 can be reduced, thereby reducing costs.
[0061] Specifically, the support component 10 can be divided into a superheated heat exchange zone 13, a two-phase condensation heat exchange zone 14, and a subcooled heat exchange zone 15. According to the heat exchange requirements of different zones, different numbers of heat exchange tubes 20 are set in the superheated heat exchange zone 13, the two-phase condensation heat exchange zone 14, and the subcooled heat exchange zone 15, which can optimize the tube arrangement structure of the heat exchange tubes 20 and improve the utilization rate of the heat exchange tubes 20. In this process, when the high-temperature refrigerant gas enters the superheated heat exchange zone 13, it cools down to a saturated state, meaning the refrigerant gas has not yet condensed into a liquid. The number of heat exchange tubes 20 in the superheated heat exchange zone 13 accounts for approximately 15% of the total number of heat exchange tubes 20. When the saturated refrigerant gas enters the two-phase condensation heat exchange zone 14, it undergoes a phase change to produce condensed liquid. The number of heat exchange tubes 20 in the two-phase condensation heat exchange zone 14 accounts for approximately 75% of the total number of heat exchange tubes 20. After the condensed liquid enters the subcooled heat exchange zone 15, it continues to exchange heat, allowing its temperature to drop to the required level. The number of heat exchange tubes 20 in the subcooled heat exchange zone 15 accounts for approximately 10% of the total number of heat exchange tubes 20.
[0062] The superheated heat exchange zone 13, the two-phase condensation heat exchange zone 14, and the subcooled heat exchange zone 15 are arranged sequentially along the refrigerant gas flow direction. Since the superheated heat exchange zone 13 does not produce condensate, the condensate in the subcooled heat exchange zone 15 does not need to be guided. Therefore, the guide plate 12 is only set in the two-phase condensation heat exchange zone 14, which can reduce the volume of the guide plate 12 and save the cost required to manufacture the guide plate 12.
[0063] Please see Figure 4 and Figure 5 In some embodiments, the outer wall of the heat exchange tube 20 is provided with fins 21, and the density of the fins 21 in the two-phase condensation heat exchange zone 14 is greater than the density of the fins 21 in the superheated heat exchange zone 13 and the subcooled heat exchange zone 15.
[0064] In this way, by making the density of the fins 21 of the heat exchange tube 20 in the two-phase condensation heat exchange zone 14 greater than the density of the fins 21 of the heat exchange tube 20 in the superheated heat exchange zone 13, the corresponding heat exchange tubes 20 can be arranged according to different zones, thereby reducing the cost required to manufacture the heat exchange tubes 20.
[0065] Specifically, fins 21 are provided on the outer wall of the heat exchange tube 20. The addition of fins 21 greatly increases the heat transfer surface area per unit area of the heat exchange tube 20, thereby increasing the amount of heat exchanged per unit time and significantly enhancing the heat exchange capacity of the heat exchange tube 20. According to the differences in heat exchange properties in different regions, different models of heat exchange tubes 20 are set in the superheated heat exchange zone 13, the two-phase condensation heat exchange zone 14, and the subcooled heat exchange zone 15. That is, the density of fins 21 set in the two-phase condensation heat exchange zone 14 can be greater than the density of fins 21 in the superheated heat exchange zone 13 and the subcooled heat exchange zone 15, so as to reduce the cost required to arrange the heat exchange tubes 20. For example, the superheated heat exchange zone 13 and the subcooled heat exchange zone 15 are sensible heat exchange zones, and their heat exchange areas are smaller than those of the two-phase condensation heat exchange zone 14. This allows for a lower density of the fins 21, reducing the cost of the condenser 100. The two-phase heat exchange zone is a latent heat exchange zone, which requires a larger heat exchange area. This allows for a higher density of the fins 21, improving heat exchange performance.
[0066] Please see Figure 2 and Figure 6 In some embodiments, the support assembly 10 includes a support plate 16, and the first fixing plate 11 includes a boss 115. The first fixing plate 11 and the support plate 16 are connected through the boss 115 so that the first fixing plate 11 and the support plate 16 are spaced apart and form a liquid guiding channel 161.
[0067] Thus, by connecting the boss 115 on the first fixing plate 11 to the support plate 16 to form a liquid guiding channel 161, the condensed liquid can be prevented from being blocked by the first fixing plate 11.
[0068] Specifically, the support assembly 10 further includes a support plate 16, which is disposed at the bottom of the first fixed plate 11 so that the support plate 16 can support the first fixed plate 11. The first fixed plate 11 has a protrusion 115 on its end face near the support plate 16. There can be multiple protrusions 115, which connect the first fixed plate 11 and the support plate 16, forming a liquid guiding channel 161 between them. The liquid guiding channel 161 allows condensed liquid dripping onto the support plate 16 to flow freely, preventing condensed liquid from being blocked between the multiple first fixed plates 11.
[0069] Please see Figure 1 , Figure 2 and Figure 6In some embodiments, a flow guiding space 163 is formed between the surface of the support plate 16 away from the first fixing plate 11 and the inner wall of the housing 30 of the condenser 100. Both ends of the support plate 16 are respectively connected to the inner wall of the housing 30 of the condenser 100 through a connecting channel 162. The connecting channel 162 connects the flow guiding space 163 and the liquid guiding channel 161, so that the condensed liquid enters the flow guiding space 163.
[0070] Thus, by providing connecting channels 162 at both ends of the support plate 16, the connecting channels 162 connect the flow guiding space 163 and the liquid guiding channel 161 formed between the support plate 16 and the shell 30, so that the condensed liquid can flow from the liquid guiding channel 161 into the flow guiding space 163 for heat exchange, thereby further improving the heat exchange efficiency of the condenser 100.
[0071] Specifically, a flow guiding space 163 is formed between the surface of the support plate 16 facing away from the first fixed plate 11 and the bottom wall of the housing 30 of the condenser 100. The flow guiding space 163 can accommodate condensed liquid and guide the condensed liquid into the liquid outlet 32. Furthermore, two ends of the support plate 16 respectively form a connecting channel 162 between the support plate 16 and the inner wall of the housing 30 of the condenser 100, so that the connecting channel 162 can connect the flow guiding space 163 and the liquid guiding channel 161 and guide the condensed liquid. Thus, after the condensed liquid in the liquid guiding channel 161 enters the connecting channel 162, it is guided by the connecting channel 162 into the flow guiding space 163.
[0072] Please see Figure 2 and Figure 6 In some embodiments, the support plate 16 is connected to a plurality of second fixing plates 164 on the surface opposite to the first fixing plate 11. The plurality of second fixing plates 164 are staggered on the inner wall of the flow guiding space 163. The second fixing plates 164 are provided with a plurality of second fixing hole units 165. Each second fixing hole unit 165 includes three second fixing holes 1651. The three second fixing holes 1651 are arranged in a triangular shape along the flow direction of the condensate. The second fixing holes 1651 are used to fix the heat exchange tube 20 through which the plurality of second fixing plates 164 pass.
[0073] Thus, by setting a second fixing plate 164 within the flow guiding space 163, the heat exchange tubes 20 can be fixed within the flow guiding space 163 for heat exchange, thereby improving heat exchange efficiency. Furthermore, the triangular arrangement of the heat exchange tubes 20 allows the condensate to form a laminar flow, resulting in low flow resistance and accelerating the discharge of the condensate.
[0074] Specifically, a second fixing plate 164 is fixedly disposed on the surface of the support plate 16 opposite to the first fixing plate 11. The second fixing plate 164 can be used to fix the heat exchange tube 20 and prevent the heat exchange tube 20 from moving during heat exchange. There can be multiple second fixing plates 164, which can be staggered on the inner wall of the flow guiding space 163, so that the condensate can be repeatedly deflected in the flow guiding space 163, thereby increasing the heat exchange frequency of the condensate.
[0075] The second fixing plate 164 is provided with a plurality of second fixing hole units 165, which can be used to fix the heat exchange tubes 20 and arrange the heat exchange tubes 20 according to the second fixing hole units 165. Each second fixing hole unit 165 includes three second fixing holes 1651, which can fix the heat exchange tubes 20 passing through the plurality of second fixing plates 164. The three second fixing holes 1651 can be arranged in a triangular shape along the flow direction of the condensate, that is, the three heat exchange tubes 20 can be arranged in a triangular shape along the direction of gravity. The triangular heat exchange tubes 20 can make the condensate form a laminar flow, and the laminar flow has low flow resistance, which can accelerate the discharge of the condensate in the guide space 163.
[0076] Please see Figure 1 and Figure 7 In some embodiments, the condenser 100 includes a housing 30 and a gas equalization assembly 40. The housing 30 is provided with an air inlet 31, a liquid outlet 32 and a receiving cavity 33. The air inlet 31 and the liquid outlet 32 are disposed opposite to each other on the side wall of the housing 30, and the air inlet 31 communicates with the receiving cavity 33. The liquid outlet 32 communicates with the flow guiding space 163. The gas equalization assembly 40 is connected to the top wall of the housing 30 and covers the air inlet 31. The gas equalization assembly 40 is spaced apart from the heat exchange tube 20. The support plate 16 is connected to the bottom wall of the housing 30 and covers the liquid outlet 32.
[0077] Thus, by providing an air inlet 31 and a liquid outlet 32 on the housing 30, high-temperature refrigerant gas can enter the receiving cavity 33 for heat exchange, and the condensate formed after heat exchange can be discharged from the receiving cavity 33 through the liquid outlet 32, thereby realizing the condensation process of the refrigerant gas. By providing a gas equalization component 40 to cover the air inlet 31, the refrigerant gas flow entering from the air inlet 31 can be blocked, reducing the flow rate of the refrigerant gas and preventing damage caused by the refrigerant gas directly impacting the heat exchange tube 20.
[0078] Specifically, the condenser 100 includes a housing 30 and a gas distribution assembly 40. The housing 30 is provided with an air inlet 31, a liquid outlet 32, and a receiving cavity 33. The air inlet 31 allows refrigerant gas to flow into the receiving cavity 33 for heat exchange, while the liquid outlet 32 discharges the condensate generated during heat exchange in the receiving cavity 33. The air inlet 31 is located on the top wall of the housing 30, and the liquid outlet 32 is located on the bottom wall of the housing 30. The air inlet 31 and the liquid outlet 32 are positioned opposite each other, allowing the air inlet 31 to communicate with the receiving cavity 33 and the liquid outlet 32 to communicate with the flow guide space 163.
[0079] The gas equalization component 40 can be fixedly installed on the top wall of the housing 30 and cover the air inlet 31, thereby blocking the high-speed, high-temperature refrigerant airflow entering the receiving cavity 33 from the air inlet 31 and reducing the flow rate of the refrigerant airflow. Furthermore, the gas equalization component 40 is spaced apart from the heat exchange tube 20, which can prevent the high-speed refrigerant airflow from directly contacting the heat exchange tube 20 and causing damage to the heat exchange tube 20.
[0080] The support plate 16 can be fixedly connected to the bottom wall of the shell 30, and the support plate 16 can cover the liquid outlet 32, so that the condensed liquid can be blocked by the support plate 16 and enter the flow guide space 163 for heat exchange again.
[0081] Please see Figure 7 In some embodiments, the air distribution assembly 40 includes an air distribution hole 41, which is located outside the projection of the air inlet 31 onto the air distribution assembly 40.
[0082] Thus, by providing a gas equalization hole 41 on the gas equalization component 40, the refrigerant gas entering from the air inlet 31 can be uniformly introduced into the receiving cavity 33.
[0083] Specifically, the gas distribution assembly 40 includes gas distribution holes 41, which allow refrigerant airflow entering the receiving cavity 33 from the air inlet 31 to pass through. The gas distribution holes 41 are all the same size and are located outside the projection of the air inlet 31 onto the gas distribution assembly 40. This prevents the refrigerant airflow from flowing directly out of the gas distribution holes 41 without being blocked by the gas distribution assembly 40 to reduce its flow velocity, thereby preventing damage to the heat exchange tube 20 and extending its service life.
[0084] Please see Figure 7 and Figure 8 In some embodiments, the air distribution holes 41 are provided corresponding to the first flow guiding region 112 and the second flow guiding region 113.
[0085] Thus, by correspondingly setting the gas equalization holes 41 in the first guide region 112 and the second guide region 113, the refrigerant gas can be uniformly introduced into the first guide region 112 and the second guide region 113, thereby improving the heat exchange efficiency of the condenser 100.
[0086] Specifically, the positions of the equalizing holes 41 on the equalizing assembly 40 can correspond to the first guide region 112 and the second guide region 113, so that the refrigerant airflow can enter the first guide region 112 and the second guide region 113 evenly. For example, the number of first fixing plates 11 is 5, which can divide the equalizing assembly 40 into six regions B1 to B6, and the number of guide plates 12 is 6, which can divide the guide region into seven guide regions A1 to A7. Thus, the equalizing holes 41 can be evenly arranged in the combined area formed by the six regions B1 to B6 and the seven guide regions A1 to A7, such as B1A1, B1A2, B1A7, B2A1, B2A2, B2A7...B6A1, B6A2, B6A7.
