Abstract
Description
Technical Field
[0001] This utility model relates to the field of radiator technology, and in particular provides a meandering water-cooled radiator. Background Technology
[0002] An Insulated Gate Bipolar Transistor Module (IGBT) is an integrated circuit module that combines power components such as IGBTs and diodes. It is highly effective in high-voltage and high-current applications and is widely used in power electronics, especially in devices requiring efficient control of high-power currents. It has broad applications in industrial automation, frequency converters, rail transportation, electric vehicles, and renewable energy systems.
[0003] Traditional heat dissipation methods for electronic devices generally include air cooling, oil cooling, and water cooling. Among them, water cooling can quickly transfer the heat generated by the IGBT module to the water cooling system by circulating coolant to the water cooling plate, thereby achieving efficient heat dissipation.
[0004] However, conventional water cooling methods are difficult to guarantee the temperature uniformity of IGBT modules and have low heat dissipation efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a bypass-type water-cooled radiator, which aims to solve the problems of low heat dissipation efficiency and poor heat dissipation uniformity of existing water-cooled radiators.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] This application provides a bypass-type water-cooled radiator, including a housing and a water-cooling plate. The housing has a mounting surface for placing an IGBT module, and the water-cooling plate is disposed on the housing and abuts against the mounting surface. The water-cooling plate has a water inlet and a water outlet, and the water-cooling plate also has a first water channel connected to the water inlet and a second water channel connected to the water outlet.
[0008] The first water channel corresponds to the mounting surface, and the first water channel and the second water channel are arranged vertically in the height direction of the box body, and the first water channel and the second water channel are connected.
[0009] The beneficial effects of this utility model are as follows: The bypass-type water-cooled radiator provided by this utility model has a first water channel and a second water channel on its water-cooling plate. The first water channel corresponds to the mounting surface, and the first and second water channels are arranged vertically along the height of the housing and are connected to each other. That is, by arranging the first and second water channels in a vertically stacked manner, the distance between the inlet and outlet can be shortened to ensure the flow rate of the coolant in each water channel, accelerate the heat exchange with the IGBT module on the mounting surface, thereby improving the heat exchange efficiency and reducing the footprint of the water-cooling plate. At the same time, since only the first water channel corresponds to the mounting surface, the temperature change of the coolant during heat exchange is smaller, thereby further improving the temperature consistency of the IGBT module during heat dissipation.
[0010] In some embodiments, the first waterway includes at least two first branch channels and at least one first intermediate channel. Each first branch channel extends along the length of the tank and is arranged side by side along the width of the tank. Adjacent first branch channels are connected end to end through the first intermediate channel. The first first branch channel is connected to the inlet and the last first branch channel is connected to the second waterway.
[0011] By adopting the above technical solution, the first waterway is divided into multiple first branch channels and first intermediate channels, and the arrangement is in a detour, which can increase the contact area with the IGBT module.
[0012] In some embodiments, in the height direction of the housing, the projection of at least one of the first branch channels falls within the projection of the mounting surface.
[0013] By adopting the above technical solution, the heat exchange efficiency between the first branch channel and the IGBT module can be improved.
[0014] In some embodiments, the second waterway includes at least two second branch channels and at least one second intermediate channel. Each second branch channel extends along the length of the tank and is arranged side by side along the width of the tank. Adjacent second branch channels are connected end to end through the second intermediate channel. The first second branch channel is connected to the last first branch channel, and the last second branch channel is connected to the outlet.
[0015] By adopting the above technical solution, the second waterway is divided into multiple second branch channels and second intermediate channels, and the arrangement is in a meandering manner.
[0016] In some embodiments, the cross-sectional area of the first branch channel is smaller than the cross-sectional area of the second branch channel; and / or,
[0017] The cross-sectional area of the first intermediate channel is smaller than that of the second intermediate channel.
[0018] By adopting the above technical solution, the flow rate of the coolant in the first water channel is higher than that in the second water channel, thereby improving the heat exchange efficiency between the water-cooled plate and the IGBT module.
[0019] In some embodiments, in the height direction of the housing, the projection of each of the first branch channels falls within the projection of one of the second branch channels.
[0020] By adopting the above technical solution, the overall structure of the first water channel is more compact, so as to ensure that the flow rate of the coolant in the first water channel is higher.
[0021] In some embodiments, in the height direction of the housing, the projection of each of the first branch channels falls within the projection of the first second branch channel.
[0022] By adopting the above technical solution, the overall structure of the first water channel is more compact, so as to ensure that the flow rate of the coolant in the first water channel is high.

[0037] Please refer to Figures 1 to 5This application provides a bypass water-cooled radiator, including a housing 10 and a water-cooling plate 20. The housing 10 has a mounting surface 10a for placing an IGBT module 100. The water-cooling plate 20 is disposed on the housing 10 and abuts against the mounting surface 10a. The water-cooling plate 20 has an inlet 20a and an outlet 20b. The water-cooling plate 20 also has a first water channel 20c connected to the inlet 20a and a second water channel 20d connected to the outlet 20b.
[0038] The first water channel 20c corresponds to the mounting surface 10a, and the first water channel 20c and the second water channel 20d are arranged vertically in the height direction of the housing 10, and the first water channel 20c and the second water channel 20d are connected.
[0039] Understandably, the enclosure 10 is the main structure of the bypass water-cooled heat sink, used to support and carry various components. For example, the mounting surface 10a of the enclosure 10 is used for mounting the IGBT module 100, and the water-cooled plate 20 is also located inside the enclosure 10 to support the water-cooled plate 20.
[0040] The water-cooled plate 20 is used to dissipate heat from heat-generating components such as the IGBT module 100. External cooling medium enters the water-cooled plate 20 through the inlet 20a and exits through the outlet 20b, forming a cooling medium circulation system to cool the IGBT module 100. Specifically, the cooling medium enters the first water channel 20c through the inlet 20a and exchanges heat with the IGBT module 100 at the first water channel 20c. After heat exchange, the cooling medium flows into the second water channel 20d and finally exits through the outlet 20b, interacting with external heat exchange devices.
[0041] The water-cooled plate 20 provided in this application uses a detour arrangement of the first water channel 20c and the second water channel 20d in the height direction of the housing 10 to cool the water. This minimizes the space occupied by the water-cooled plate 20 in the horizontal plane. At the same time, the detour arrangement in the vertical direction can further increase the flow rate of the cooling medium in each water channel or reduce the corresponding pumping power.
[0042] The bypass-type water-cooled radiator provided by this utility model has a water-cooling plate 20 with a first water channel 20c and a second water channel 20d. The first water channel 20c corresponds to the mounting surface 10a, and the first water channel 20c and the second water channel 20d are arranged vertically in the height direction of the housing 10 and are connected. That is, by arranging the first water channel 20c and the second water channel 20d in a vertically stacked manner, the distance between the inlet 20a and the outlet 20b can be shortened to ensure the flow rate of the coolant in each water channel, accelerate the heat exchange with the IGBT module 100 on the mounting surface 10a, thereby improving the heat exchange efficiency and reducing the footprint of the water-cooling plate 20. At the same time, since only the first water channel 20c corresponds to the mounting surface 10a, the temperature change of the coolant during heat exchange is smaller, thereby further improving the consistency of the operating temperature of the IGBT module 100 during the heat dissipation process.
[0043] Please refer to Figure 4 In some embodiments, the first waterway 20c includes at least two first branch channels 20c1 and at least one first intermediate channel 20c2. Each first branch channel 20c1 extends along the length of the housing 10 and is arranged side by side along the width of the housing 10. Two adjacent first branch channels 20c1 are connected end to end through the first intermediate channel 20c2. The first branch channel 20c1 at the beginning is connected to the inlet 20a, and the last first branch channel 20c1 is connected to the second waterway 20d.
[0044] For example, such as Figure 4 As shown, there are two first branch channels 20c1 and one first intermediate channel 20c2. The two first branch channels 20c1 extend along the length of the housing 10 and are arranged side by side along the width of the housing 10. The first intermediate channel 20c2 is located on the same side of the two first branch channels 20c1.
[0045] Thus, the first waterway 20c is divided into multiple first branch channels 20c1 and first intermediate channels 20c2, and the arrangement is in a meandering manner, which can increase the contact area with the IGBT module 100.
[0046] Please refer to Figure 3 and Figure 4 In some embodiments, in the height direction of the housing 10, the projection of at least one first branch channel 20c1 falls within the projection of the mounting surface 10a.
[0047] Optionally, such as Figure 4 As shown, each first branch channel 20c1 falls within the projection of the mounting surface 10a in the height direction of the housing 10, thereby increasing the contact area with the IGBT module 100.
[0048] This improves the heat exchange efficiency between the first branch channel 20c1 and the IGBT module 100.
[0049] Please refer to Figure 3 and Figure 5 In some embodiments, the second waterway 20d includes at least two second branch channels 20d1 and at least one second intermediate channel 20d2. Each second branch channel 20d1 extends along the length of the housing 10 and is arranged side by side along the width of the housing 10. Two adjacent second branch channels 20d1 are connected end to end through the second intermediate channel 20d2. The first second branch channel 20d1 is connected to the last first branch channel 20c1, and the last second branch channel 20d1 is connected to the outlet 20b.
[0050] For example, as shown in Figures 3 to 4 Figure 5 As shown, there are two second branch channels 20d1 and one second intermediate channel 20d2. The two second branch channels 20d1 extend along the length of the housing 10 and are arranged side by side along the width of the housing 10. The second intermediate channel 20d2 is located on the same side of the two second branch channels 20d1.
[0051] Thus, the second waterway 20d is divided into multiple second branch channels 20d1 and second intermediate channels 20d2, and the arrangement is in a meandering manner.
[0052] Please refer to Figure 4 and Figure 5 In some embodiments, the cross-sectional area of the first branch channel 20c1 is smaller than the cross-sectional area of the second branch channel 20d1; and / or,
[0053] The cross-sectional area of the first intermediate channel 20c2 is smaller than the cross-sectional area of the second intermediate channel 20d2.
[0054] Thus, the flow rate of the coolant in the first water channel 20c is higher than that in the second water channel 20d, thereby improving the heat exchange efficiency between the water-cooled plate 20 and the IGBT module 100.
[0055] Please refer to Figure 4 and Figure 5 In some embodiments, in the height direction of the housing 10, the projection of each first branch channel 20c1 falls within the projection of one of the second branch channels 20d1.
[0056] Thus, the overall structure of the first water channel 20c is more compact, so as to ensure a higher flow rate of coolant in the first water channel 20c.
[0057] Please refer to Figure 4 and Figure 5 In some embodiments, in the height direction of the housing 10, the projection of each first branch channel 20c1 falls within the projection of the first and second branch channel 20d1.
[0058] Thus, the overall structure of the first water channel 20c is more compact, so as to ensure that the flow rate of the coolant in the first water channel 20c is high. At the same time, the coolant in the first water channel 20c can quickly enter the second water channel 20d.
[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
