Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation structures, and in particular relates to an asymmetric radiator structure. Background Art

[0002] As living standards improve, new energy vehicles are becoming increasingly popular. Until there's a revolutionary breakthrough in battery pack energy density, shortening the charging time of new energy vehicles is a better way to alleviate consumers' anxiety about battery life than increasing range by carrying more batteries. Therefore, fast charging, especially super-fast charging, has become a development trend in the new energy industry.

[0003] Super-fast charging facilities are mainly composed of charging piles, charging guns and radiators. Among them, the radiator is responsible for cooling the entire charging facility and the vehicle battery pack. When new energy vehicles are fast-charging, the charging gun generates a huge amount of heat, which greatly increases safety risks and affects normal use. The common cooling method nowadays is to pass the cooling medium through the charging gun to cool the charging gun, and then the cooling medium enters the radiator through the pipe to cool the cooling medium. However, the existing radiator does not take into account that the viscosity of the cooling medium will increase at low temperatures, causing the pressure in the channel to increase, affecting the overall stability of the radiator. Therefore, if the fast-charging facility is to operate stably and long-term, an efficient radiator is required to cool the entire facility.

[0004] Therefore, in order to solve the above technical problems, it is necessary to provide an asymmetric heat sink structure.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

A plurality of evenly distributed first microchannel flat tubes are connected between the second delivery pipe and the third delivery pipe, the first delivery pipe and the third delivery pipe, and the first delivery pipe and the fourth delivery pipe.

When the cooling medium is below 0 degrees Celsius, the cooling medium can be quickly discharged from the second liquid outlet pipe, reducing the pipeline pressure of the first microchannel flat tube and the second microchannel flat tube.

[0012] In one or more embodiments of the present invention, the heat dissipation drive assembly includes a support frame plate for supporting a pair of support ring tubes, thereby providing support force for a pair of heat dissipation motors and a heat dissipation fan.

The heat dissipation motor is provided in the support ring tube for driving the heat dissipation fan to rotate, thereby providing power for the wind-blown heat dissipation;

[0014] A plurality of thin supporting rods are fixedly connected between the heat dissipation motor and the supporting ring tube, and are used to fix the heat dissipation motor, thereby preventing the heat dissipation motor from shaking or tilting, and improving the stability of the device.

[0015] In one or more embodiments of the present invention, a cooling fan is installed on the output shaft of the heat dissipation motor, which is used to accelerate the flow of gas after rotation, thereby improving the heat dissipation effect of the multiple first microchannel flat tubes and the second microchannel flat tubes, and further improving the heat dissipation effect of the cooling medium.

[0016] In one or more embodiments of the present invention, a sealing cover is fixedly installed on one side of the support frame plate to conveniently and quickly absorb the heat generated by the device, so as to improve the heat dissipation and cooling effect.

[0017] Compared with the existing technology, the utility model increases the heat dissipation area of ​​the radiator through corresponding structural design, and improves the heat exchange efficiency between the microchannel surface and the external gas, thereby increasing the pressure drop of the pipeline, improving the heat dissipation efficiency, and increasing the outlet of the radiator to ensure good fluidity of the cooling medium.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0030] like Figures 1-8 As shown, an asymmetric radiator structure in one embodiment of the present invention includes a first delivery pipe 1 and a third delivery pipe 2. A second delivery pipe 101 is provided on one side of the first delivery pipe 1, and a fourth delivery pipe 201 is provided on one side of the third delivery pipe 2. Both are used to transport cooling medium, allowing the cooling medium to circulate in a Z-shaped pattern, thereby improving the heat dissipation effect of the cooling medium. A plurality of evenly distributed first microchannel flat tubes 3 are connected between the second delivery pipe 101 and the third delivery pipe 2, the first delivery pipe 1 and the third delivery pipe 2, and the first delivery pipe 1 and the fourth delivery pipe 201. A plurality of evenly distributed second microchannel flat tubes 301 are also fixedly connected between the second delivery pipe 101 and the third delivery pipe 2. Both the first microchannel flat tubes 3 and the second microchannel flat tubes 301 are used to transport cooling medium.

[0031] Specifically, the number of microchannels within the first microchannel flat tube 3 is 18 to 25. The number of microchannels within the second microchannel flat tube 301 is 1 to 10. This allows the cooling medium to flow even after increasing viscosity at temperatures below 0°C, facilitating rapid discharge through the second liquid outlet pipe 601. Preferably, the number of microchannels within the first microchannel flat tube 3 is 20. The number of microchannels within the second microchannel flat tube 301 is 2.

[0032] like Figure 1As shown, the second delivery pipe 101 is fixedly connected with a liquid inlet pipe 4 for introducing cooling medium into the second delivery pipe 101 to facilitate the circulation of the cooling medium. The fourth delivery pipe 201 is fixedly connected with a first liquid outlet pipe 5 for discharging the cooling medium after heat dissipation and cooling, thereby realizing the circulation of the cooling medium.

[0033] like Figure 1-Figure 5 As shown, the third delivery pipeline 2 is equipped with an outlet control assembly 6, which includes a second liquid outlet pipeline 601, which is used to accelerate the discharge of the cooling medium, thereby relieving the pressure within the first microchannel flat tube 3 and the second microchannel flat tube 301 and reducing the probability of pipeline damage. The second liquid outlet pipeline 601 is equipped with a control valve 602, which is used to control the opening and closing of the second liquid outlet pipeline 601, thereby facilitating the flow of the cooling medium. When the cooling medium temperature is above 0 degrees Celsius, the cooling medium is unlikely to be discharged from the second liquid outlet pipeline, thereby allowing the cooling medium to fully dissipate heat. When the cooling medium temperature is below 0 degrees Celsius, the cooling medium can be quickly discharged from the second liquid outlet pipeline 601, reducing the pipeline pressure of the first microchannel flat tube 3 and the second microchannel flat tube 301.

[0034] Preferably, the control valve 602 can be a stop valve, a solenoid valve, a temperature-controlled pressure valve, etc., so that the staff can remotely control the opening and closing, thereby reducing the pressure on the staff, and can also automatically open when the temperature is lower than the set value, thereby improving the intelligence of the device.

[0035] like Figures 1-8 As shown, a heat dissipation drive assembly 7 is installed on one side of the plurality of first microchannel flat tubes 3. The heat dissipation drive assembly 7 includes a support frame plate 701 for supporting a pair of support ring tubes 702, thereby providing support for a pair of heat dissipation motors 703 and a heat dissipation fan 704.

[0036] like Figure 6 As shown, a pair of support ring tubes 702 are mounted on the support frame 701 to support a heat dissipation motor 703 and a heat dissipation fan 704, ensuring more stable heat dissipation. The heat dissipation motor 703 is housed within the support ring tubes 702 to rotate the heat dissipation fan 704, thereby providing power for airflow and heat dissipation. A plurality of thin support rods 705 are fixedly connected between the heat dissipation motor 703 and the support ring tubes 702 to secure the heat dissipation motor 703, thereby preventing it from shaking or tilting and improving the stability of the device.

[0037] Specifically, a cooling fan 704 is mounted on the output shaft of the heat dissipation motor 703. This fan is used to accelerate the flow of gas upon rotation, thereby improving the heat dissipation of the plurality of first and second microchannel flat tubes 301, and thereby improving the heat dissipation of the cooling medium. A sealing cover 706 is fixedly mounted on one side of the support frame 701, which is used to enclose the support frame 701 and the first and second microchannel flat tubes 301. This allows for the rapid removal of heat generated by the heat dissipation drive assembly 7 after activation, thereby improving the heat dissipation and cooling effect.

[0038] In specific use, the cooling medium is introduced into the second delivery pipe 101 through the liquid inlet pipe 4, and then the cooling medium enters the third delivery pipe 2 through a portion of the first microchannel flat tubes 3 and a plurality of second microchannel flat tubes 301. The cooling medium is then transported to the first delivery pipe 1 again through a portion of the first microchannel flat tubes 3, and then transported to the fourth delivery pipe 201 through the first microchannel flat tubes 3. Finally, the cooling medium is discharged through the first liquid outlet pipe 5.

[0039] The heat dissipation motor 703 is started, and the heat dissipation fan 704 is driven by the heat dissipation motor 703 to rotate, thereby accelerating the flow of the contact gas between the outer surfaces of the plurality of first micro-channel flat tubes 3 and the second micro-channel flat tubes 301, so that the cooling medium is forced to dissipate heat and cool in the micro-channels.

[0040] When the temperature of the cooling medium is lower than 0 degrees Celsius, the viscosity of the cooling medium will increase rapidly, causing the pressure drop of the cooling medium in the first microchannel flat tube 3 and the second microchannel flat tube 301 to be too large. At this time, the staff starts the control valve 602, so that the cooling medium in the third delivery pipe 2 is directly discharged from the second liquid outlet pipe 601, increasing the speed of cooling medium discharge, thereby reducing the pressure in the pipe and the probability of pipe damage, so that the entire device can work stably.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
