Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger processing equipment, and specifically to a condenser that provides rapid heat dissipation. Background Technology

[0002] In refrigeration equipment, the condenser is a heat exchanger that achieves refrigeration. It utilizes the flow of refrigerant inside the core tubes and the flow of air in the gaps between the fins to transfer heat from the outside air to the high-pressure atomized refrigerant injected through the small orifice of the expansion valve through the heat transfer effect of the flat tubes and fins. The refrigerant quickly absorbs heat and vaporizes into a gaseous state. Due to the heat absorption and vaporization, the surface temperature of the evaporator drops. The air blown from the blower continuously flows through the evaporator core, is cooled, and is blown out from the air outlet, thus cooling the interior of the vehicle.

[0003] In existing technologies, U-shaped heat exchange tube units are usually set at an angle, that is, the two straight tubes are staggered so that both straight tubes are located on the airflow drive path, thereby increasing the cooling effect.

[0004] However, in this setup, the fan is located on one side of the condenser, meaning that the distance between the two straight tubes in the same heat exchanger unit and the fan is not uniform, resulting in inconsistent cooling effects and different temperatures for the two straight tubes in the same heat exchanger unit, thus causing uneven temperature distribution in the heat exchanger. Utility Model Content

[0005] In order to solve the above-mentioned problems in the prior art, the present invention provides a condenser for rapid heat dissipation.

[0006] The above-mentioned problems of this utility model are solved by the following technical solution: A condenser for rapid heat dissipation includes a main body mounted on the airflow drive path of a fan, the main body including a plurality of fins arranged parallel to the airflow drive path, and an S-shaped heat exchange tube assembly coiled through the fins. The heat exchange tube group is provided with a first tube group and a second tube group in parallel along the direction of the airflow driving path, and the airflow driving direction is from the second tube group to the first tube group. The medium inlet of the heat exchange tube group is located in the first tube group, and the medium outlet is located in the second tube group.

[0007] By adopting the above technical solution, the heat exchange tube assembly is S-shaped and runs through multiple parallel fins, increasing the heat exchange area; the fins are parallel to the airflow drive path, improving airflow efficiency, strengthening the coordinated heat dissipation of the tube assembly and fins, and further optimizing the temperature distribution.

[0008] A further configuration of the above technical solution is as follows: the first tube group includes a plurality of first heat exchange tubes, the second tube group includes a plurality of second heat exchange tubes, the plurality of first heat exchange tubes are arranged sequentially along the length direction of the fins, and the plurality of second heat exchange tubes are arranged sequentially along the length direction of the fins.

[0009] By adopting the above technical solution, the first and second tube groups are independently formed on a plane, and the straight tubes in the same tube group are at the same distance from the fan, resulting in uniform heat dissipation conditions and reducing temperature fluctuations within the tube group.

[0010] The above technical solution is further configured as follows: the first heat exchange tube includes a first straight tube that passes through the fins in sequence, and a first bent tube that connects to the adjacent first straight tube; The second heat exchange tube includes a second straight tube that passes through the fins in sequence, and a second bent tube that connects to the adjacent second straight tube; Multiple first straight tubes and multiple second straight tubes are arranged in parallel along the length of the fins.

[0011] A further configuration of the above technical solution is as follows: the first straight pipe has a first axis, the second straight pipe has a second axis, and the first axis and the second axis are offset.

[0012] By adopting the above technical solution, the axes of the first straight pipe and the second straight pipe are misaligned to avoid the airflow being completely blocked by the first pipe group, so that some low-temperature airflow can directly contact the second pipe group, thereby enhancing the heat dissipation capacity of the second pipe group and alleviating the problem of reduced heat dissipation efficiency of the second pipe group caused by the temperature rise of the airflow.

[0013] A further provision of the above technical solution is that the main body also includes a connecting bend for connecting the first heat exchange tube and the second heat exchange tube, the connecting bend being located at the output end of the first heat exchange tube and the input end of the second heat exchange tube.

[0014] A further provision of the above technical solution is that the connecting bend is inclined relative to the first bend and / or the second bend.

[0015] A further configuration of the above technical solution is as follows: the fin has a first end and a second end along its length, the connecting bend and the medium inlet are respectively located at different ends of the fin, and the medium inlet and the medium outlet are located at the same end.

[0016] By adopting the above technical solution, the medium inlet and outlet are located at the same end of the fins, which shortens the external pipeline connection distance, facilitates installation and maintenance, and reduces pipeline heat loss.

[0017] A further provision of the above technical solution is that the main body also includes a mounting bracket, which is disposed on the outer surface of the fins and is provided with a bending mechanism for mounting the fan.

[0018] By adopting the above technical solution, a mounting bracket with bending is provided on the outside of the main body, which can directly fix the fan, simplifying the overall assembly process and improving the integration of the equipment.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The airflow driving direction and the medium conveying direction are set in opposite directions, so that the airflow first cools the low-temperature zone, so that the cooling medium output from medium outlet b is output in the form of air temperature, and then cools the high-temperature zone, so that the cooling medium in the high-temperature zone enters the low-temperature zone in the form of temperature lower than the input temperature. By using staged cooling and temperature equalization design, the thermal stress caused by excessive local temperature difference in heat exchange tubes is reduced, thus extending the service life of the equipment. An optimized heat dissipation structure can achieve higher heat dissipation efficiency with the same fan power, or reduce fan speed while meeting heat dissipation requirements, thereby reducing energy consumption and noise.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-4 As shown, this embodiment discloses a condenser for rapid heat dissipation.

[0027] A condenser for rapid heat dissipation includes a main body 200 installed on the airflow drive path of a fan 100. The main body 200 includes a plurality of fins 210 arranged parallel to the airflow drive path, and a heat exchange tube assembly 220 coiled in an S-shape through the fins 210. The heat exchange tube group 220 is provided with a first tube group 221 and a second tube group 222 parallel to each other along the direction of the airflow driving path, and the airflow driving direction is from the second tube group 222 to the first tube group 221. The medium inlet a of the heat exchange tube group 220 is located in the first tube group 221, and the medium outlet b is located in the second tube group 222.

[0028] The above is the basic scheme of this embodiment.

[0029] Specific reference Figure 1 As shown, the fin 210 is a strip-shaped rectangular sheet. The heat exchange tube assembly 220 is arranged through the fin 210 along the thickness direction of the rectangular sheet. Furthermore, multiple tube assemblies are arranged sequentially along the length direction of the rectangular sheet, thereby forming multiple S-shaped structures with their ends connected and coiled in the fin 210.

[0030] Furthermore, the fan 100 is located on one side of the main body 200, and the airflow driving direction is along the width direction of the fins 210. That is, it can drive the air in the gap between adjacent fins 210, thereby cooling the fins 210 and the heat exchange tube assembly 220.

[0031] Reference Figure 3 As shown, the heat exchange tube assembly 220 has two rows arranged on the fins 210, each row consisting of multiple heat exchange tube assemblies 220. The two rows of heat exchange tube assemblies 220 are arranged along the airflow drive path. The fins 210 have a first cooling side 201 and a second cooling side 202 along their width direction. The first cooling side 201 is closer to the fan 100, and the second cooling side 202 is relatively farther away from the fan 100. The two rows of pipes of the heat exchange tube assembly 220 are respectively arranged on the first cooling side 201 and the second cooling side 202, with a first tube assembly 221 forming a plane on the first cooling side 201 and a second tube assembly 222 forming a plane on the second cooling side 202.

[0032] Based on the above settings, when the equipment is cooling, the fan 100 is started to drive the airflow around the condenser and the fan 100. The driving direction is from the second cooling side 202 to the first cooling side 201. That is, the second tube group 222 of the second cooling side 202 is cooled first, and then the airflow passes through the first tube group 221 of the first cooling side 201.

[0033] The cooling principle is as follows: The cooling medium is input through the medium inlet a in the first tube group 221. When the cooling medium flows through the tubes to the second tube group 222, it has already absorbed some heat through the tube wall of the second tube group 221. That is, the temperature of the cooling medium in the second tube group 222 is lower than the input temperature. When the airflow passes through the second cooling side 202, it absorbs the temperature of the second tube group 222 and quickly cools the cooling medium in the second tube group 222, so that the cooling medium is cooled to the air temperature when it is output through the medium outlet b. After the airflow passes through the first cooling side 202, it flows to the second cooling side. At this time, the airflow temperature is higher than the air temperature, but lower than the temperature of the cooling medium in the first tube group 221. Therefore, the airflow can cool the first tube group 221 of the first cooling side 201 again, thereby achieving the effect of absorbing the temperature of the cooling medium, so that the cooling medium enters the second tube group 222 in a form slightly higher than the air temperature.

[0034] Compared to the cooling principle in the prior art, this embodiment reverses the airflow drive direction, so that the airflow first cools the low-temperature zone, and the cooling medium output from medium outlet b is output in the form of air temperature, and then cools the high-temperature zone, so that the cooling medium in the high-temperature zone enters the low-temperature zone in the form of temperature lower than the input temperature.

[0035] In other embodiments, if the medium inlet a and medium outlet b are reversed, the above effect can be achieved by changing the airflow direction of the fan 100.

[0036] Specifically, the first tube group 221 includes a plurality of first heat exchange tubes, and the second tube group 222 includes a plurality of second heat exchange tubes. The plurality of first heat exchange tubes are arranged sequentially along the length direction of the fins 210, and the plurality of second heat exchange tubes are arranged sequentially along the length direction of the fins 210.

[0037] In this embodiment, the airflow driving direction is defined as the X direction, the length direction of the fin 210 is defined as the Y direction, and the width direction of the fin 210 is defined as the Z direction.

[0038] Multiple first heat exchange tubes are arranged along the Y-axis and have a length on the X-axis, thereby forming a first heat exchange plane on the first heat exchange side of the fin 210; similarly, multiple second heat exchange tubes form a second heat exchange plane on the second heat exchange side of the fin 210; during the flow process, the airflow cools the second heat exchange tubes on the second heat exchange plane and then cools the first heat exchange tubes on the first heat exchange plane.

[0039] Meanwhile, the heat exchange medium is input from the medium inlet a and flows along the first heat exchange tube within the first heat exchange plane. During the flow, some of the heat of the heat exchange medium is absorbed by the first heat exchange tube. When the medium flows to the second heat exchange tube, it has formed a medium at medium temperature. The medium-temperature heat exchange medium flows along the second heat exchange tube, and during the flow, the heat is absorbed by the airflow, rapidly forming a heat exchange medium at air temperature, which is output from the medium outlet b.

[0040] To achieve the S-shaped structure of the heat exchange tube assembly 220, in this embodiment, the first heat exchange tube includes a first straight tube 221.1 that passes through the fins 210 in sequence, and a first bent tube 221.2 that connects to the adjacent first straight tube 221.1; The second heat exchange tube includes a second straight tube 222.1 that passes through the fins 210 in sequence, and a second bent tube 222.2 that connects to the adjacent second straight tube 222.1; Multiple first straight tubes 221.1 and multiple second straight tubes 222.1 are arranged in parallel along the length of fin 210.

[0041] In this embodiment, the heat exchange tube structure is consistent with the U-shaped heat exchange tube structure in the prior art. The difference is that in the U-shaped structure of this embodiment, while the first straight tube 221.1 of the same first heat exchange tube extends along the X-axis, the two first straight tubes 221.1 are arranged parallel in the Y-axis direction, thereby forming a first heat exchange plane on the XY plane; similarly, the second heat exchange tube forms a second heat exchange plane on the XY plane.

[0042] Based on the above configuration, the multiple first heat exchange tubes in the first tube group 221 are placed on the same plane, so that when the airflow passes through the plane, all tube parts in the first tube group 221 are cooled synchronously to ensure that the cooling efficiency of the first tube group 221 is consistent. Similarly, the multiple second heat exchange tubes in the second tube group 222 are placed on the same plane, and the airflow cools all tube parts in the plane synchronously, so the cooling efficiency of the second tube group 222 is consistent.

[0043] Preferably, in this embodiment, the first straight pipe 221.1 has a first axis L, and the second straight pipe 222.1 has a second axis M, with the first axis L and the second axis M being staggered.

[0044] Based on the above configuration, the first straight pipe 221.1 and the second straight pipe 222.1 are offset in the airflow driving direction. That is to say, the first straight pipe 221.1 and the second straight pipe 222.1 will not obstruct each other. When the airflow passes through the second straight pipe 222.1, it passes by the side of the second straight pipe 222.1, absorbs the heat from the outer surface of the second straight pipe 222.1 and the surrounding air, and then flows directly toward the first straight pipe 221.1, thereby being able to approach the outer wall of the first straight pipe 221.1 and absorb the heat of the first straight pipe 221.1.

[0045] In this embodiment, the main body 200 further includes a connecting bend 223 for connecting the first heat exchange tube and the second heat exchange tube. The connecting bend 223 is located at the output end of the first heat exchange tube and the input end of the second heat exchange tube.

[0046] Preferably, the connecting bend 223 is inclined relative to the first bend 221.2 and / or the second bend 222.2.

[0047] Specific reference Figure 4 As shown, the output end of the first tube group 221 and the input end of the second tube group 222 are offset on the Y-axis, and an inclined connecting bend 223 is set to connect them, which can maximize the medium passage length of the first tube group 221 and the medium passage length of the second tube group 222, thereby improving the heat exchange efficiency.

[0048] In addition, in this embodiment, the fin 210 has a first end and a second end along its length, the connecting bend 223 and the medium inlet a are respectively located at different ends of the fin 210, and the medium inlet a and the medium outlet b are located at the same end.

[0049] By placing the medium inlet a and the medium outlet b on the same side of the fin 210 and at the same end of the fin 210, the medium passage within the main body 200 can be extended as much as possible, while also facilitating the connection of the medium inlet a and the medium outlet b to the pipeline.

[0050] In this embodiment, in order to make the main body 200 an integral unit, the main body 200 also includes a mounting bracket, which is disposed on the outer surface of the fin 210 and is provided with a bend 231 to install the fan 100.

[0051] There are two supports 230, which are located on the outer side of the two fins 210 at the outermost end of the main body 200 to fix the fins 210; while the fins 210 located inside are fixed by heat exchange tube assembly 220. Meanwhile, a bend 231 is provided on the bracket 230 facing the fan 100, and the fan 100 is fixed on the bend 231 with the air outlet facing the fin 210.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
