In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present application is not limited to the specific embodiments disclosed below.

In addition, the three-dimensional dimensions of length, width and depth should be included in actual fabrication.
Example 1: referring to fig. 1 to 7, for providing an automatic driving domain controller with a cooling device according to a first embodiment of the present application, in order to guide heat in the domain controller into a heat conductive sheet 103, a main control assembly 100 is provided including a domain control housing 101, a main chip 102 disposed in the domain control housing 101, and a heat conductive sheet 103 disposed at the bottom of the main chip 102; the domain control shell 101 is an external shell of the vehicle-mounted domain controller, the main chip 102 is an integral PCB (printed circuit board) on the vehicle-mounted domain controller, and the main chip 102 emits a large amount of heat when the vehicle-mounted controller operates; the heat conductive sheet 103 is made of a graphite sheet material and is bonded to the main chip 102 to conduct heat to the heat conductive sheet 103.
In order to cool the heat conducting fin 103, a cooling assembly 200 is provided, and is attached to the heat conducting fin 103, and the cooling assembly comprises a cooling channel 201, wherein a cooling liquid flows in the cooling channel 201, enters the cooling assembly 200 through a liquid inlet 206, collects heat along the route of the cooling channel 201, and finally takes away heat through a liquid outlet 207.
In order to reduce the influence of the vehicle motion on the cooling assembly 200, the fixing fins 204 and the sliding fins 205 are symmetrically arranged in the cooling channel 201, and the influence caused by the inertia and the gravity center offset of the vehicle is reduced through a backflow preventing structure formed by the fixing fins 204 and the sliding fins 205, so that the positive circulation of the cooling liquid is ensured.
The rotating wheel 202 is arranged in the cooling channel 201, the temperature sensor 203 is arranged around the rotating wheel 202 to cooperate with the rotating wheel, the gear 301 is arranged at the back of the cooling component 200 in order to take away more heat of local high-temperature components, the position of the sliding fin 205 is changed by the synchronous rotation of the gear 301 and the rotating wheel 202, the width of the central channel of the cooling channel 201 is further shortened by the flowing force of cooling liquid, most of the cooling liquid is diverted left and right, and the cooling channel 201 is retained for a longer time, so that more heat is taken away.
Through the scheme, the influence on the circulation of the cooling liquid in the motion process of the automobile is effectively reduced, and the cooling liquid is prevented from flowing back; for local overheating, the flow path of the cooling liquid is changed by utilizing the flow force of the cooling liquid, so that the cooling liquid stays at the high temperature of the PCB for a longer time, and more heat is taken away.
Example 2: referring to fig. 2-7, a second embodiment of the present application is shown, which differs from the first embodiment in that: the cooling channels 201 may be provided in the cooling assembly 200, three cooling channels 201 may be provided according to this embodiment, each cooling channel 201 is connected end to end, the cooling channel 201 is in an arrow shape, the direction of the arrow pointing is the same as the direction of the coolant flowing, the two sides of the channels in the cooling channel 201 are provided with the fixing fins 204 and the sliding fins 205, the fixing fins 204 and the sliding fins 205 are staggered on a single side of the cooling channel 201, the fixing fins 204 are fixedly connected with the inner wall of the cooling channel 201, the length of the fixing fins 204 is longer than that of the sliding fins 205, a sliding groove 205a is further provided between the upper and lower sides of the fixing fins 204, the sliding fins 205 are slidably connected with the sliding groove 205a, and the inclination angle of the fixing fins 204 and the sliding fins 205 is consistent with the arrow shape of the cooling channel 201.
Through the above-mentioned scheme, referring to fig. 3, when the cooling liquid enters the cooling channel from the liquid inlet 206, most of the cooling liquid directly flows along the central channel, and a small portion of the cooling liquid on both sides enters the gaps between the fixed fins 204 and the sliding fins 205 and flows along the gaps, and as the inclined angle of the fixed fins 204 and the sliding fins 205 is consistent with the arrow shape of the cooling channel 201, the cooling liquid still keeps the overall forward flowing trend when flowing out of the gaps, and is integrated into the cooling liquid flowing in the central channel, and the process does not affect the forward movement of the cooling liquid. When the vehicle is braked suddenly or accelerated rapidly, referring to fig. 4, the cooling liquid flows reversely in the direction of the liquid inlet 206, at this time, the cooling liquid at two sides of the central channel of the cooling channel 201 enters the gaps between the fixed fins 204 and the sliding fins 205, at this time, the cooling liquid flowing out of the gaps is flushed out along the inclined angle of the fixed fins 204 due to the opposite direction, the cooling liquid flowing in the central channel to the liquid inlet 206 forms a recoil force to prevent the cooling liquid from flowing, and a process similar to the force unloading exists in the gaps between each fixed fin 204 and the sliding fins 205, so that the reverse flow of the cooling liquid is blocked layer by layer, and the heat cannot be taken out of the cooling channel in time due to the reflux, thereby affecting the heat dissipation effect.
In order to cool the local high temperature part, a rotating wheel 202 and a temperature sensor 203 are further arranged in the cooling channel 201, the temperature sensor 203 can monitor the temperature of the heat conducting fin 103, when the temperature of the corresponding position on the heat conducting fin 103 does not reach a threshold value, the temperature sensor 203 judges that the heat conducting fin is not overheated, the rotating wheel 202 is not started, the rotating wheel 202 cannot rotate due to cooling liquid flow power, when the temperature of the corresponding position is too high to reach the threshold value, the temperature sensor 203 receives an overheat signal, the rotating wheel 202 is started, the rotating wheel 202 is released from limitation, the gear 301 arranged at the back of the cooling channel 201 is connected with the rotating wheel 202 through the flowing force of cooling liquid, namely, the rotating wheel 202 can drive the gear 301 to rotate. The gear rods 302 are provided with tooth grooves 302a which are meshed with the gear 301, and when the gear 301 rotates, the tooth grooves 302a at the upper end and the lower end of the gear rods respectively move towards the center of the gear 301 to drive the two gear rods 302 to approach each other. In the control assembly 300, a group of sliding fins 205 on the same side is penetrated by a driving rod 302, the driving rod 302 is slidably connected with the sliding fins 205, and a sliding block 302b is arranged at the end of the driving rod 302 and is embedded in a slideway 303, so that when the driving rods 302 are close to each other, the driving rod 302 pushes the same sliding fins 205 to move along the direction of a sliding groove 205a, and the two sliding fins 205 are close to each other.
Through the above scheme, when the temperature sensor 203 detects that the part is overheated, the runner 202 is started, the runner 202 starts to rotate by the flowing force of the cooling liquid, and drives the gear 301 to start to rotate, so that the two transmission rods 302 approach each other, and the two corresponding sliding fins 205 also start to approach each other, referring to fig. 7, at this time, the sliding fins 205 in the cooling channel 201 approach each other two by two, so that the central channel width of the cooling channel 201 is narrowed, most of the cooling liquid cannot flow through the central channel rapidly, so that the cooling liquid can be split to two sides, and enters into the gaps between the fixed fins 204 and the sliding fins 205, and the flowing process is changed from the original flowing process from the central process to the flowing process of most of the cooling liquid into the gap channels between the fixed fins 204 and the sliding fins 205, so that the flowing distance of the cooling liquid is increased, and the time of the cooling liquid is retained in the part is longer, thereby taking away more heat.
After the rotating wheel 202 rotates to enable the sliding fins 205 to approach, as the cooling liquid is split, the flowing force brought by the central channel is reduced, but the cooling liquid is flushed out of the gaps between the fixed fins 204 and the sliding fins 205 and can provide large flowing force, the rotating wheel 202 can be ensured not to reversely rotate to enable the sliding fins 205 to be separated; even if the sliding fins 205 are not close, the sliding fins are gradually separated, so that the passing width of the central channel is enlarged, and the central channel can pass most of cooling liquid at the moment, the rotating wheel 202 can be rotated again by the flowing force, in sum, the rotation of the rotating wheel 202 is dynamic balance, the function is realized without depending on any electrical equipment, the cooling equipment is more reliable, and meanwhile, the circulating flow power generated by the cooling air pump is also used, so that the energy-saving effect is achieved; meanwhile, when the sliding fin 205 is close, the width of the central passage is reduced, so that the backflow restriction of the cooling liquid is larger, and the taken heat is more difficult to be influenced by the movement of the vehicle, so that the cooling liquid flows back.
In order to reset the sliding fin 205, a torsion spring 301a is arranged between the gear 301 and the outer wall of the cooling channel 201, when the cooling device is deactivated, the cooling air pump is firstly disconnected, so that the cooling liquid does not circulate, at the moment, the cooling liquid cannot provide flow force, the gear 301 driven by the rotating wheel 202 rotates to overcome the restoring force of the torsion spring 301a, at the moment, the rotating wheel 202 cannot provide stress, the torsion spring 301a returns to enable the gear 301 to rotate, the transmission rod 302 is reset, the transmission rod 302 drives the sliding fin 205 to separate from each other, and the rotating shaft in the rotating wheel 202 is locked to return to the posture when the device is started.
The rest of the structure is the same as that of embodiment 1.
It should be noted that the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present application may be modified or substituted without departing from the spirit and scope of the technical solution of the present application, which is intended to be covered in the scope of the claims of the present application.
