[0063] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0064] Embodiment 1 of the present invention provides a heat dissipation structure, which includes a heat dissipation shell 10 and heat dissipation fins 20. The heat dissipation shell 10 is used to connect with the structure to be dissipated; the heat dissipation shell 10 is provided with an inlet 11 for introducing coolant and an outlet 12 for discharging coolant; the heat dissipation shell 10 encloses a heat dissipation channel. The heat dissipation fins 20 are arranged in the heat dissipation channel. The heat dissipation channel includes a first channel 31 and a second channel 32 spaced apart along the arrangement direction of the structure to be dissipated; the first channel 31 includes a first inlet portion 311, a first main body portion 312 and a first outlet portion 313 that are connected in sequence, and the second channel 32 includes a second inlet portion 321, a second main body portion 322 and a second outlet portion 323 that are connected in sequence, the first inlet portion 311 and the second inlet portion 321 are both connected to the inlet 11; the first outlet portion 313 and the second outlet portion 323 are both connected to the outlet 12; the first main body portion 312 and the second main body portion 322 are spaced apart from each other.

[0065] The heat dissipation structure provided in Example 1 of the present invention can shorten the coolant flow path of the heat dissipation channel by separately setting the first channel 31 and the second channel 32. Different parts of the heat dissipation structure can be treated with heat dissipation and cooling treatment simultaneously through the first channel 31 and the second channel 32, further improving the uniformity of heat dissipation and avoiding the coolant flow path in the heat dissipation channel being too long, which may lead to poor heat dissipation effect when the coolant flows through the corresponding part of the heat dissipation structure at the end of the path. In addition, the provision of the heat dissipation fins 20 can increase the heat dissipation area and further improve the heat dissipation effect. Therefore, the heat dissipation structure provided in this embodiment can solve the technical problem of uneven heat dissipation effect of the heat dissipation channel in the prior art.

[0066] Specifically, the structure to be dissipated heat includes power devices. The power devices are insulated gate bipolar transistors (IGBTs). Specifically, the power devices include power devices for driving a motor, power devices for driving an oil pump, and power devices for driving an air pump. Specifically, the structure to be dissipated heat also includes a DC-DC converter (DCDC). With this structural arrangement, the heat dissipation structure can dissipate heat from a variety of high-heat-generating devices, thereby improving the heat dissipation efficiency of the heat dissipation structure.

[0067] Specifically, the first channel 31 is a bent channel. With such a structural arrangement, the compactness of the heat dissipation structure can be further improved, the space occupied by the heat dissipation structure can be reduced, and thus the heat dissipation efficiency can be further improved.

[0068] Specifically, the second channel 32 is a bent channel. With such a structural arrangement, the compactness of the heat dissipation structure can be further improved, the space occupied by the heat dissipation structure can be reduced, and thus the heat dissipation efficiency can be further improved.

[0069] Specifically, the first main body portion 312 is an S-shaped channel. The second main body portion 322 is an S-shaped channel. This structural arrangement helps to slow down the flow rate of the coolant, thereby facilitating better heat dissipation of the heat dissipation structure.

[0070] Specifically, the inlet 11 and outlet 12 are both located on one side of the heat dissipation housing 10, and the second channel 32 is located on the side of the first channel 31 away from the heat dissipation housing 10. This structural arrangement improves the compactness of the layout of the inlet 11 and outlet 12 by locating both on the side of the heat dissipation housing 10, thereby facilitating the installation and use of the heat dissipation structure. Furthermore, by locating the second channel 32 on the side of the first channel 31 away from the heat dissipation housing 10, the heat dissipation area of the first channel 31 and the second channel 32 can be increased, making it easier to adapt the arrangement of the first channel 31 and the second channel 32 to the arrangement of the structure to be dissipated, thereby effectively dissipating heat from the portions of the structure to be dissipated corresponding to the first channel 31 and the second channel 32, thereby further improving heat dissipation uniformity.

[0071] In this embodiment, the first main body 312 includes multiple heat dissipation branches and multiple connecting branches. The multiple heat dissipation branches are arranged side by side, with adjacent heat dissipation branches connected by connecting branches. Heat dissipation fins 20 are disposed within the heat dissipation branches. The heat dissipation branches are configured to contact the structure to be dissipated. This structural arrangement enables the contact between the heat dissipation branches and the structure to be dissipated, allowing the coolant flowing within the heat dissipation branches to dissipate heat from the structure to be dissipated. Furthermore, the heat dissipation fins 20 disposed within the heat dissipation branches increase the heat dissipation area corresponding to the structure to be dissipated, thereby further improving the heat dissipation effect. The side-by-side arrangement of multiple heat dissipation branches also helps to increase the heat dissipation area and thus improve heat dissipation efficiency.

[0072] In this embodiment, the second main body 322 includes a plurality of cooling branches and a plurality of circulation branches. The plurality of cooling branches are arranged side by side, and two adjacent cooling branches are connected through the circulation branches. The heat dissipation fins 20 are arranged in the cooling branches. The cooling branches are used to contact the structure to be dissipated. With such a structural arrangement, the contact between the cooling branches and the structure to be dissipated can enable the coolant flowing in the cooling branches to dissipate heat for the structure to be dissipated. At the same time, the heat dissipation fins 20 are arranged in the cooling branches, which can increase the heat dissipation area in the portion corresponding to the structure to be dissipated, thereby further improving the heat dissipation effect. The side-by-side arrangement of the plurality of cooling branches also helps to increase the heat dissipation area and improve the heat dissipation efficiency.

[0073] Specifically, a plurality of heat dissipation branches are laid along the arrangement direction of the structures to be dissipated. With such a structural arrangement, the heat dissipation branches can better contact the structures to be dissipated, thereby improving the heat dissipation effect.

[0074] Specifically, a plurality of cooling branches are laid along the arrangement direction of the structures to be radiated. With such a structural arrangement, the cooling branches can better contact the structures to be radiated, thereby improving the heat dissipation effect.

[0075] Specifically, the heat dissipation fins 20 extend along the flow direction of the coolant in the heat dissipation channel. With such a structural arrangement, the heat dissipation area can be increased by the heat dissipation fins 20 while preventing the heat dissipation fins 20 from obstructing the flow of the coolant in the heat dissipation channel.

[0076] Specifically, the heat dissipation fins 20 are strip-shaped members. Specifically, the heat dissipation fins 20 are wavy or V-shaped structures.

[0077] In this embodiment, if Figure 2 As shown, the arrows in the figure indicate the direction of coolant flow. The first main body 312 includes a first heat dissipation branch channel 3121, a first connecting branch channel 3122, a second heat dissipation branch channel 3123, a second connecting branch channel 3124, and a third heat dissipation branch channel 3125, which are connected end to end. The first heat dissipation branch channel 3121, the second heat dissipation branch channel 3123, and the third heat dissipation branch channel 3125 are arranged side by side. This structural arrangement helps to slow the flow of coolant through the arrangement of the first heat dissipation branch channel 3121, the first connecting branch channel 3122, the second heat dissipation branch channel 3123, the second connecting branch channel 3124, and the third heat dissipation branch channel 3125, thereby facilitating better heat dissipation from the heat dissipation structure.

[0078] In this embodiment, the second main body 322 includes a first cooling branch channel 3221, a first circulation branch channel 3222, a second cooling branch channel 3223, a second circulation branch channel 3224, and a third cooling branch channel 3225, which are connected end to end. The first cooling branch channel 3221, the second cooling branch channel 3223, and the third cooling branch channel 3225 are arranged side by side. This structural arrangement helps to slow the flow of the coolant through the arrangement of the first cooling branch channel 3221, the first circulation branch channel 3222, the second cooling branch channel 3223, the second circulation branch channel 3224, and the third cooling branch channel 3225, thereby facilitating better heat dissipation from the heat dissipation structure.

[0079] Specifically, the heat dissipation housing 10 comprises a housing portion 13 and a cover portion 14. The cover portion 14 is configured to cover the housing portion 13. The side of the housing portion 13 facing away from the cover portion 14 is configured to connect to a portion of the structure to be dissipated. The side of the cover portion 14 facing away from the housing portion 13 is configured to connect to another portion of the structure to be dissipated. This structural arrangement facilitates adjustment, inspection, and maintenance of the internal structure of the heat dissipation channel by separating the housing portion 13 and the cover portion 14. Furthermore, this arrangement allows both sides of the heat dissipation housing 10 to dissipate heat from the structure to be dissipated, further improving the efficiency of the heat dissipation structure.

[0080] Specifically, the shell portion 13 and the cover portion 14 are connected by friction stir welding.

[0081] Specifically, the housing 13 includes an outer shell and a deflector. The outer shell encloses an inner cavity, and the deflector is disposed within the inner cavity to form a heat dissipation channel. This structural arrangement allows the housing 13 to carry the flow of coolant, while the deflector guides the flow of coolant, thereby forming a first channel 31 and a second channel 32 within the heat dissipation housing 10.

[0082] Specifically, the first inlet portion 311 includes a first opening, a first inlet channel 3111, and a first connection port 3112 connected in sequence. The first opening is connected to the inlet 11, and the first connection port 3112 is connected to the first main body portion 312. The second inlet portion 321 includes a second opening, a second inlet channel 3211, and a second connection port 3212 connected in sequence. The second opening is connected to the inlet 11, and the second connection port 3212 is connected to the second main body portion 322. The opening of the first opening and the opening of the second opening are both adjustable. With such a structural setting, the flow rate of the coolant in the first channel 31 and the second channel 32 can be changed by adjusting the opening of the first opening and the opening of the second opening, respectively, so that the flow rate of the coolant in the first channel 31 and the second channel 32 can be adjusted as needed, thereby further improving the uniformity of heat dissipation.

[0083] Specifically, in order to improve the compactness of the heat dissipation channel, the first inlet flow channel 3111 and the second inlet flow channel 3211 are arranged at a preset angle, which is 90°.

[0084] Specifically, the second connection port 3212 is located on a side of the second channel 32 away from the first channel 31. The first outlet 313 and the second outlet 323 are arranged adjacent to each other. This structural arrangement can improve the compactness of the heat dissipation channel layout and also facilitate the coolant flowing out of the first channel 31 and the coolant flowing out of the second channel 32 to flow out of the outlet 12 together.

[0085] In this embodiment, the heat dissipation structure further includes a first temperature sensor, the detection end of which is disposed on the first main body portion 312. The first temperature sensor is connected to the first opening, and the opening of the first opening is adjusted based on the detection result of the first temperature sensor. With this structural arrangement, the first temperature sensor can detect the temperature within the first main body portion 312, thereby timely adjusting the opening of the first opening according to the temperature environment and changing the flow rate of the coolant within the first channel 31. This arrangement facilitates heat dissipation and cooling of the heat dissipation structure according to actual temperature conditions, thereby improving the efficiency of the heat dissipation structure.

[0086] In this embodiment, the heat dissipation structure further includes a second temperature sensor, the detection end of which is disposed on the second main body portion 322. The second temperature sensor is connected to the second opening, and the opening of the second opening is adjusted based on the detection result of the second temperature sensor. With this structural arrangement, the second temperature sensor can detect the temperature within the second main body portion 322, thereby timely adjusting the opening of the second opening according to the temperature environment and changing the flow rate of the coolant within the second channel 32. This arrangement facilitates heat dissipation and cooling of the heat dissipation structure according to actual temperature conditions, thereby helping to improve the efficiency of the heat dissipation structure.

[0087] like Figures 1 to 6 As shown, the second embodiment of the present invention provides a controller, comprising the heat dissipation structure provided in the first embodiment, a main housing 1, and a power module 2. A portion of the main housing 1 forms a heat dissipation housing 10 of the heat dissipation structure. The power module 2 is disposed on the main housing 1 and connected to the heat dissipation structure; the power module 2 forms at least a portion of the structure to be dissipated.

[0088] The controller provided in the second embodiment of the present invention can shorten the coolant flow path of the heat dissipation channel by separately disposing the first channel 31 and the second channel 32. The first channel 31 and the second channel 32 can simultaneously perform heat dissipation and cooling treatment on different parts of the heat dissipation structure, further improving the uniformity of heat dissipation and avoiding the situation where the coolant flow path in the heat dissipation channel is too long, resulting in poor heat dissipation effect when the coolant flows through the corresponding part of the heat dissipation structure at the end of the path. In addition, the provision of the heat dissipation fins 20 can increase the heat dissipation area, further improving the heat dissipation effect. Therefore, the controller provided in this embodiment can solve the technical problem of uneven heat dissipation effect of the heat dissipation channel in the prior art.

[0089] Specifically, power module 2 is a power device used to drive the motor. It includes multiple IGBTs. These include two W-phase IGBTs, two V-phase IGBTs, and two U-phase IGBTs. The two W-phase IGBTs are connected in parallel, the two V-phase IGBTs are connected in parallel, and the two U-phase IGBTs are connected in parallel. Specifically, the IGBTs are coated with thermal grease and mounted on the front of the heat dissipation housing 10.

[0090] Specifically, the coolant flowing through the first channel 31 passes through two W-phase IGBTs and one V-phase IGBT in sequence. The coolant flowing through the second channel 32 passes through two U-phase IGBTs and one V-phase IGBT in sequence.

[0091] Specifically, the power module 2 is connected to the outer surface of the heat dissipation housing 10; the heat dissipation fins 20 of the heat dissipation structure are arranged in the portion of the heat dissipation housing 10 corresponding to the power module 2. This structural arrangement increases the heat dissipation area in the portion corresponding to the structure to be dissipated, thereby further improving the heat dissipation effect.

With this arrangement, different structures to be cooled can be cooled and cooled respectively through the two sides of the heat dissipation structure, thereby improving the utilization efficiency of the heat dissipation structure. Specifically, the DC converter module 3, the oil pump drive module 4, and the air pump drive module 5 are coated with heat dissipation silicone grease and installed on the back of the heat dissipation housing 10.

[0093] Specifically, the controller further includes an inlet pipe 6 and an outlet pipe 7. The inlet pipe 6 is used to be inserted at the inlet 11 of the heat dissipation structure to introduce coolant into the heat dissipation housing 10. The outlet pipe 7 is used to be inserted at the outlet 12 of the heat dissipation structure to discharge the coolant flowing out of the heat dissipation housing 10.

[0094] Specifically, the controller further includes a battery positive and negative electrode output terminal 8 and a three-phase output terminal 9 , and the battery positive and negative electrode output terminal 8 and the three-phase output terminal 9 are both arranged on the main shell 1 .

[0095] Specifically, the controller is a five-in-one controller, which integrates a power module 2 , a PDU (current distribution socket), a DC converter module 3 , an oil pump drive module 4 and an air pump drive module 5 .

[0097] The vehicle provided by the third embodiment of the present invention can shorten the coolant flow path of the heat dissipation channel by separately disposing the first channel 31 and the second channel 32. The first channel 31 and the second channel 32 can simultaneously perform heat dissipation and temperature reduction treatment on different parts of the heat dissipation structure, further improving the uniformity of heat dissipation and avoiding the coolant flow path in the heat dissipation channel being too long, which would result in poor heat dissipation effect when the coolant flows through the corresponding part of the heat dissipation structure at the end of the path. In addition, the provision of the heat dissipation fins 20 can increase the heat dissipation area, further improving the heat dissipation effect, and thus further increasing the service life of the vehicle. Therefore, the vehicle provided by this embodiment can solve the technical problem of uneven heat dissipation effect of the heat dissipation channel in the prior art.

For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0104] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0105] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
