[0002] The condenser is a core heat exchange component in a refrigeration system and a heat exchange system, and its main function is to cool the high-temperature and high-pressure gaseous refrigerant discharged by the compressor in the refrigeration system into liquid refrigerant through heat exchange, thereby realizing the continuous operation of the refrigeration cycle and being widely used in many fields such as air conditioners, refrigerators, industrial refrigeration equipment, all automobile thermal management systems and the like. With the development of various equipment towards high efficiency, miniaturization and energy saving, higher and higher requirements are put forward for the heat exchange efficiency, space utilization rate and operation stability of the condenser.

[0003] However, in the actual application process of the existing condenser, there are still many problems to be solved. On the one hand, the condensing pipes of the existing condenser are mostly arranged horizontally or approximately horizontally, and are arranged in the heat dissipation chamber. The flow of the refrigerant in the condensing pipe is mainly driven by its own gravity and system pressure, but the horizontally arranged branch pipes can cause uneven distribution of the refrigerant in the pipe, and some pipe sections are prone to refrigerant retention or slow flow, thereby affecting the heat exchange efficiency, causing insufficient condensation of the refrigerant, and increasing the energy consumption of the refrigeration system. On the other hand, the air flow path of the heat dissipation chamber of the existing condenser is not reasonable, the hot air discharge efficiency is low, and the hot air is prone to accumulate in the chamber and cannot be quickly discharged from the heat dissipation outlet, thereby reducing the heat exchange temperature difference between the cooling medium and the condensing pipe and further restricting the improvement of the heat exchange efficiency.

How to improve the heat exchange efficiency and the refrigerant circulation efficiency through structural optimization in a limited space has become an important research direction in the field of condenser design.

[0049] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0050] Please refer to Figures 1 to 7The condenser structure 1000 provided in the embodiment includes a shell structure 100 and a condensing pipe 200. The shell structure 100 is provided with a plurality of heat dissipation chambers 110. The length of the heat dissipation chamber 110 is arranged in the vertical direction. The top of the heat dissipation chamber 110 is provided with a heat dissipation outlet 120. The bottom of the heat dissipation chamber 110 is provided with a heat dissipation inlet 130 to form a hot air upward airflow flow path in the interior of the heat dissipation chamber 110. The condensing pipe 200 includes a front end main pipe 210, a plurality of branch pipes 220, and a rear end main pipe 230. The plurality of branch pipes 220 are arranged in the plurality of heat dissipation chambers 110. The front end of the plurality of branch pipes 220 is in communication with the front end main pipe 210. The rear end of the plurality of branch pipes 220 is in communication with the rear end main pipe 230. The shell structure 100 is made of copper or aluminum, preferably aluminum. In addition, the cross section of the heat dissipation chamber 110 can be rectangular, circular, or other special-shaped structures.

[0051] As can be seen, the condenser structure 1000 of the embodiment can efficiently take away the heat generated in the condensation process by arranging a plurality of heat dissipation chambers 110 extending in the vertical direction in the shell structure 100, cooperating with the heat dissipation inlet 130 and the heat dissipation outlet 120 to form a natural hot air upward airflow flow path. The condensing pipe 200 adopts the structure of the front end main pipe 210, the plurality of branch pipes 220, and the rear end main pipe 230. The branch pipes 220 are arranged in the heat dissipation chambers 110, thereby increasing the contact area of the condensing pipe 200 with the airflow, improving the condensation and heat dissipation efficiency, promoting the smooth circulation of the condensing medium, and further ensuring the stable and efficient operation of the condenser.

[0052] By dividing the condensing medium into a plurality of parallel branch pipes 220, the contact area of the condensing pipe 200 with the airflow in the heat dissipation chamber 110 is significantly increased, so that the heat can be more fully and quickly transferred to the air, thereby effectively improving the overall condensation efficiency. At the same time, the shunt structure can reduce the medium flow and flow rate in a single pipe, making the condensation process more stable, reducing flow resistance and pressure loss, and helping to improve the operation stability and energy saving effect of the condenser, which can effectively reduce the working efficiency of the compressor 410 of the refrigeration system.

[0053] As shown in Figures 1 to 3 In the embodiment, the plurality of branch pipes 220 are arranged in the vertical direction one by one and correspondingly arranged in the heat dissipation chambers 110. The front end of the branch pipe 220 is higher than the rear end of the branch pipe 220 in the horizontal direction. As shown in Figure 4As shown, in one possible implementation, the branch pipes 220 can be arranged in a curved and surrounding manner in the heat dissipation chamber 110, and a plurality of branch pipes 220 can be arranged in an array along the height direction. Of course, in other possible implementations, the branch pipes 220 can be arranged in a curved and surrounding manner in the heat dissipation chamber 110, and a plurality of branch pipes 220 can be arranged in an array along the horizontal direction or the vertical direction. In summary, a plurality of branch pipes 220 can be combined in multiple layers or combined in the horizontal direction and the vertical direction, and the arrangement of the branch pipes 220 should not be considered as a limitation of the present application.

[0054] In the present embodiment, as shown in Figures 5 to 6 The shell 300 is provided with a mounting cavity 310, and the bottom of the mounting cavity 310 is open to form an air inlet 311. A vertical exhaust passage 320 is arranged in the shell 300, and the top of the exhaust passage 320 is open to form an air outlet 321. The bottom of the exhaust passage 320 communicates with the mounting cavity 310. Preferably, a fan (not shown in the figure) is mounted at the bottom of the shell 300 to further drive the air flow in the shell 300 from bottom to top. The fan is a fan assembly in the prior art.

[0055] By accommodating the condenser body in the mounting cavity 310 of the shell 300 and using the opening at the bottom of the mounting cavity 310 as the air inlet 311, external cold air can smoothly enter the mounting cavity 310 under natural convection and under the driving of the fan, thereby providing a stable low-temperature air source for the condenser. The vertical exhaust passage 320 in the shell 300 communicates with the mounting cavity 310, and the top of the exhaust passage 320 is open to form the air outlet 321, so that the heated air can be quickly discharged along the vertical direction, forming an overall air flow path from bottom to top. This structure not only strengthens the air flow around the condenser, but also effectively avoids the retention of hot air around the condenser, thereby significantly improving the heat dissipation efficiency. In addition, the arrangement of the shell 300 can also protect the internal condenser structure 1000, reduce the influence of external dust, debris, etc. on the performance of the condenser, and improve the reliability and service life of the equipment.

[0056] Preferably, as shown in Figure 5As shown, the top portion of the exhaust passage 320 is provided with a radially inwardly convex extension to form a converging protrusion 340, so as to reduce the caliber of the top portion of the exhaust passage 320 through the converging protrusion 340, thereby making the flow rate of the gas at the top portion of the exhaust passage 320 greater than the flow rate of the gas at the remaining portion of the exhaust passage 320. According to Bernoulli's principle in fluid mechanics, the flow rate of the gas will be significantly increased when passing through the converging area, thereby enhancing the pumping effect in the exhaust passage 320, enabling the hot air in the installation cavity 310 to be pumped out more quickly, forming a more intense airflow from bottom to top. The increase in flow rate also reduces the static pressure at the top portion of the exhaust passage 320, further promoting the entry of cold air from the bottom air inlet 311, improving the overall heat dissipation efficiency. In addition, the high-speed airflow helps to reduce the retention of hot air near the condenser, avoiding heat accumulation, thereby improving the condensing performance and operating stability of the condenser.

[0057] In the present embodiment, as shown in Figure 5 The shell 300 is provided with a first through hole 350 and a second through hole 360, the front end manifold 210 passes through the first through hole 350 to extend out of the shell 300, and the rear end manifold 230 passes through the second through hole 360 to extend out of the shell 300.

[0058] Preferably, as shown in Figures 1 to 4 The plurality of heat dissipation chambers 110 are arranged in a transverse direction and a longitudinal direction. By arranging the heat dissipation chambers 110 in an array in both the transverse direction and the longitudinal direction, more heat dissipation chambers 110 can be arranged in a limited installation space, thereby significantly increasing the contact area between the branch pipes 220 of the condenser pipe 200 and the air, improving the overall heat dissipation capacity. This arrangement also enables the cold air to form a more uniform airflow distribution in the shell structure 100, reducing airflow dead angles and avoiding heat accumulation in some areas, further improving the heat dissipation efficiency. In addition, the array structure helps to reduce the thermal load of the individual heat dissipation chambers 110, making the overall temperature distribution of the condenser more uniform, improving the operating stability and service life.

[0059] In one possible implementation, the plurality of heat dissipation chambers 110 are arranged only in the transverse direction.

[0060] Preferably, as shown in Figures 1 to 6As shown, the cavity wall of each heat dissipation chamber 110 is provided with heat dissipation fins 140 to increase the heat dissipation area through the heat dissipation fins 140, wherein the cavity wall of the heat dissipation chamber 110 is provided with a plurality of vertically arranged insertion slots, and the heat dissipation fins 140 can be inserted into the insertion slots correspondingly, so that the user can adjust the number of heat dissipation fins 140 according to the required heat dissipation amount, and the cavity wall of the heat dissipation chamber 110 is arranged with the buckle structure in the prior art to limit and fix the heat dissipation fins 140 through the buckle structure. By arranging the heat dissipation fins 140 on the cavity wall of the heat dissipation chamber 110, the heat dissipation area can be significantly increased, so that the heat in the heat dissipation chamber 110 can be more fully and quickly transferred to the air flowing through, thereby effectively improving the heat dissipation efficiency. The arrangement of the heat dissipation fins 140 helps to reduce the working temperature of the heat dissipation chamber 110 and the condenser pipe 200, and improves the overall operation stability and service life of the condenser.

[0061] Preferably, as Figures 1 to 6 shown, the outer pipe wall of the branch pipe 220 abuts against the cavity wall of the heat dissipation chamber 110, wherein by directly contacting the outer pipe wall of the branch pipe 220 with the cavity wall of the heat dissipation chamber 110, the heat conduction performance between the condenser pipe 200 and the heat dissipation chamber 110 can be significantly enhanced, so that the heat released by the refrigerant in the condenser pipe 200 can be more quickly and effectively transferred to the cavity wall of the heat dissipation chamber 110, and further transferred to the air flowing through the heat dissipation chamber 110 through the cavity wall. This close-fitting structure reduces the thermal resistance in the heat transfer path, improves the overall heat transfer efficiency, and helps to make the temperature distribution of the condenser pipe 200 more uniform, avoiding local overheating, thereby improving the operation stability and service life of the condenser.

[0062] Preferably, the top of the heat dissipation chamber 110 is radially inwardly convexly extended to form a convex structure 150 to reduce the caliber of the top of the heat dissipation chamber 110 through the convex structure 150, so that the flow rate of the gas at the top of the heat dissipation chamber 110 is greater than the flow rate of the gas in the remaining part of the heat dissipation chamber 110. By forming a converging structure at the top of the heat dissipation chamber 110, the flow area of the top is reduced, according to the principle of fluid mechanics, the flow rate of the gas will be significantly increased when passing through this converging area, thereby enhancing the air extraction effect inside the heat dissipation chamber 110 and promoting the rapid upward discharge of hot air. The increase in flow rate also reduces the static pressure at the top of the heat dissipation chamber 110, which is conducive to the continuous entry of cold air from the bottom heat dissipation inlet 130, forming a more stable and intense airflow from bottom to top. This structure can effectively reduce the retention of hot air inside the heat dissipation chamber 110, avoid heat accumulation, improve the heat dissipation efficiency, and thus improve the condensation performance and operation stability of the condenser.

[0063] According to the above embodiments, the application further provides a refrigeration system, which comprises a condenser structure 1000, a compressor 410, a capillary tube 420, a drying filter 430 and an evaporator 440, wherein the condenser structure 1000 is any one of the above embodiments.

[0064] The design of the air flow path from bottom to top in the condenser, the multi-branch pipe 220 structure, the heat dissipation fins 140 and the top converging structure can quickly and effectively transfer the heat released by the refrigerant in the condensation process to the air, thereby significantly improving the overall heat exchange efficiency of the refrigeration system. The improvement of the condensation efficiency helps to reduce the working load of the compressor 410, reduce the energy consumption, and at the same time make the operation of the system more stable and reliable. In addition, the optimization of the condenser structure 1000 can also accelerate the condensation speed of the refrigerant, improve the efficiency of the refrigeration cycle, and make the refrigeration system have stronger refrigeration capacity under the same power consumption, thereby improving the user experience.

[0065] According to the above embodiments, the application further provides a refrigeration device, which comprises a condenser structure 1000 and a cabinet 510, wherein the condenser structure 1000 is arranged in the cabinet 510 to form a refrigeration space 512, and the condenser structure is any one of the above embodiments. The design of the air flow path from bottom to top in the condenser, the multi-branch pipe 220 structure, the heat dissipation fins 140 and the top converging structure can quickly and effectively transfer the heat released by the refrigerant in the condensation process, thereby significantly improving the overall heat exchange efficiency of the refrigeration device. The improvement of the condensation efficiency helps to reduce the working load of the compressor 410, reduce the energy consumption, and at the same time make the temperature of the refrigeration space 512 more stable, thereby improving the preservation effect of the refrigeration device. In addition, the optimization of the condenser structure 1000 can also accelerate the refrigeration cycle speed, make the refrigeration space 512 reach the set temperature faster, and improve the user experience.

[0066] Preferably, the bottom of the cabinet 510 is provided with a cold air layer 511, which is arranged corresponding to the refrigeration space 512 to cool the gas in the cold air layer 511, and the cold air layer 511 has a first opening 511a and a second opening 511b, wherein the first opening 511a is in communication with the external environment, and the second opening 511b is in communication with the heat dissipation inlet 130.

[0067] By utilizing the low temperature of the refrigeration space 512 to pre-cool the air in the cold air layer 511, the air entering the condenser heat dissipation inlet 130 itself has a lower temperature, thereby significantly improving the heat exchange efficiency of the condenser and making the condensing effect more efficient. The cold air layer 511 inhales normal temperature air from the outside through the first opening 511a, and after being cooled in the refrigeration space 512, the air flows to the condenser through the second opening 511b, forming an auxiliary heat dissipation path that utilizes the cold energy of the refrigeration equipment itself. Not only does this improve energy utilization efficiency, but it also reduces the working load of the compressor 410 and reduces energy consumption. In addition, this structure can make the condenser always contact with relatively stable low-temperature airflow, which helps to maintain the stability of the refrigeration equipment operation, improve the temperature control accuracy of the refrigeration space 512, and improve the overall preservation effect. The excess cold air at the bottom of the refrigeration equipment is recycled and turned into treasure.

[0068] Preferably, a one-way valve 520 is further included, which is arranged at the first opening 511a to allow gas to enter the cold air layer 511 from the external environment through the first opening 511a via the one-way valve 520.

[0069] The one-way valve 520 is a one-way air valve structure in the prior art, which can be a manually openable valve structure in other possible implementations. By configuring the one-way valve 520, it is ensured that external air can only enter the cold air layer 511 from the external environment in one direction, and the cooled air in the cold air layer 511 is prevented from flowing back to the external environment, thereby ensuring that the cold air layer 511 always maintains a stable low-temperature airflow supply. This one-way flow structure helps to maintain the stability of the air temperature at the condenser heat dissipation inlet 130, avoids the decrease in condensing efficiency caused by the mixing of cold and hot air, and also reduces energy loss and improves the overall energy efficiency of the refrigeration equipment.

[0070] Preferably, the cabinet 510 is provided with a containing space 514 and a heat conduction channel 513. The bottom of the containing space 514 is in communication with the cold air layer 511, the top of the containing space 514 is in communication with the bottom of the heat conduction channel 513, and the top of the heat conduction channel 513 is in communication with the external environment, so that the airflow in the cabinet 510 flows from bottom to top.

[0071] Through the cooperation of the accommodation space 514 and the heat conduction channel 513, the air flow organization inside the refrigeration equipment can be further optimized, so that the air cooled in the cold air layer 511 continuously flows upwards along the accommodation space 514 and the heat conduction channel 513 under the action of natural convection, forming a stable air flow from bottom to top. This structure not only enhances the heat dissipation effect of the condenser, but also timely discharges the excess heat inside the refrigeration equipment, avoiding the accumulation of heat at the bottom or inside of the cabinet 510, thereby improving the overall heat dissipation efficiency and operation stability of the equipment. At the same time, the air flow path from bottom to top helps to improve the utilization rate of cold air in the cold air layer 511, reduce energy waste, reduce the load of the compressor 410, and improve the energy efficiency of the refrigeration equipment. In addition, this structure can also promote air circulation inside the cabinet 510, reduce local temperature, and prolong the service life of the equipment.

[0072] In one possible implementation, as shown in Figure 12 The bottom of the cabinet 510 is provided with a cold air layer 511, and the cold air layer 511 is correspondingly arranged with the refrigeration space 512 to cool the gas in the cold air layer 511. The cooling pipeline 600 has a first part extending into the cold air layer 511 and a second part extending into the heat dissipation chamber 110, and the fan 700 is arranged in the cooling pipeline 600 to circulate the gas in the cooling pipeline 600.

[0073] By directly contacting the cooling pipeline 600 with the low-temperature air in the cold air layer 511, the low-temperature air in the cooling pipeline 600 enters the heat dissipation chamber 110 to cool the pipe wall of the second part, which can effectively reduce the temperature of the heat dissipation chamber 110 and significantly improve the efficiency of the subsequent condensation process. This structure makes full use of the cold energy generated by the refrigeration space 512, realizes the secondary utilization of energy, and helps to reduce the working load of the compressor 410 and improve the overall energy efficiency of the refrigeration equipment.

[0074] It is worth mentioning that the condenser can be applied to refrigerators, freezers, fresh-keeping cabinets, air conditioners, etc. All heat dissipation systems of refrigeration equipment on the market can use the condenser structure of the present application, and the application range is wide.

[0075] In the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

[0076] By setting multiple vertically extending heat dissipation chambers 110 in the shell structure 100, cooperating with the heat dissipation inlet 130 and the heat dissipation outlet 120 to form a natural air flow path of hot air from bottom to top, the heat generated in the condensation process can be efficiently taken away; The condenser pipe 200 adopts the structure of the front end main pipe 210, the plurality of branch pipes 220 and the rear end main pipe 230, the branch pipes 220 are arranged in the heat dissipation chamber 110, which increases the contact area of the condenser pipe 200 and the airflow, improves the condensation and heat dissipation efficiency, promotes the smooth circulation of the condensing medium, and further guarantees the stable and efficient operation of the condenser.
