It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element or one or more intervening elements can be present therebetween.

In addition, the terms "first", "second" and the like are merely used for the purpose of description and cannot be understood as indicating or implying relative importance.
[0033] Unless otherwise defined, all technical and scientific terms used in the present specification have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the present specification includes any and all combinations of one or more related listed items.
[0034] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.
[0035] As Figures 1-3As shown, the auxiliary driving controller 1 provided by one of the embodiments of the present application comprises a shell 2, a mainboard 3 and a heat dissipation assembly 4. The shell 2 is provided with a receiving cavity 201, and the mainboard 3 and the heat dissipation assembly 4 are both received in the receiving cavity 201. The heat dissipation assembly 4 comprises at least one heat pipe 41 and at least one temperature control piece 42. The heat pipe 41 and the temperature control piece 42 are both in abutment with the mainboard 3, and each heat pipe 41 is vertically arranged on the mainboard 3 along the thickness direction Y of the mainboard 3. The heat pipe 41 is used to absorb the heat transferred by the mainboard 3 when the temperature of the mainboard 3 is higher than a first working temperature threshold of the mainboard 3. The temperature control piece 42 is used to cool the side of the mainboard 3 when the ambient temperature is higher than the first working temperature threshold of the mainboard 3, and is used to heat the side of the mainboard 3 when the temperature of the mainboard 3 is lower than a second working temperature threshold of the mainboard 3.
[0036] In this way, when the temperature of the mainboard 3 is higher than the first working temperature threshold of the mainboard 3, the heat pipe 41 absorbs the heat generated by the mainboard 3 during working, so as to play a role in cooling the mainboard 3, thereby reducing the risk of abnormal working of the mainboard 3. Moreover, when the ambient temperature is lower than the second working temperature threshold of the mainboard 3, the heat pipe 41 can be used to transfer heat to the mainboard 3 by working to generate heat, so as to accelerate the recovery of the mainboard 3 to the temperature during normal working, thereby being convenient to use.
[0037] It should be noted that when the mainboard 3 works and generates a large amount of heat, the temperature of the mainboard 3 will rise. If the mainboard 3 is in a high-temperature environment higher than the temperature required for normal working for a long time, the working efficiency of some functional devices on the mainboard 3 will decrease, and even there is a risk of being burned out. Moreover, when the ambient temperature of the mainboard 3 is lower than the temperature required for normal working of the mainboard 3, the functional devices on the mainboard 3 cannot work normally, thereby affecting the starting speed of the auxiliary driving controller 1. Therefore, it is necessary to ensure that the mainboard 3 works in a predetermined temperature range.
[0038] The first working temperature threshold and the second working temperature threshold of the mainboard 3 respectively represent two critical values of the temperature range required for normal working of the mainboard 3, which depend on the working temperature range of each group of functional devices on the mainboard 3. The first working temperature threshold of the mainboard 3 represents the maximum temperature during normal working of the mainboard 3. When the temperature of the mainboard 3 is higher than the first working temperature threshold, the working efficiency of the functional devices (such as chips) on the mainboard 3 will decrease. The second working temperature threshold of the mainboard 3 represents the minimum temperature during normal working of the mainboard 3. When the ambient temperature is lower than the second working temperature threshold, the working efficiency of the functional devices (such as chips) on the mainboard 3 will also decrease, which will affect the starting speed of the auxiliary driving controller 1.
[0039] The heat pipe 41 in the embodiment adopts an existing structure. For the convenience of understanding, the structure of the heat pipe 41 is briefly described below.
[0040] The heat pipe 41 is a heat transfer element with extremely high thermal conductivity, which is composed of a pipe shell, a wick and an end cover. After the pipe is pumped to a negative pressure, an appropriate amount of phase change medium liquid is filled in the pipe, so that the wick capillary porous material close to the inner wall of the pipe is filled with phase change medium. The pipe shell is usually made of high thermal conductivity metal material, such as copper or copper alloy. It is generally divided into evaporation section and condensation section, and the evaporation section is closer to the device requiring heat dissipation than the condensation section. The heat dissipation effect achieved by using the heat pipe 41 is better than that of air cooling or liquid cooling. When working, the evaporation section of the heat pipe 41 is heated and reaches the temperature of the phase change medium in the heat pipe 41. The phase change medium liquid in the capillary tube of the heat pipe 41 rapidly vaporizes and absorbs heat. After vaporization, the temperature inside the heat pipe 41 rises, and the gas pressure increases. The vaporized medium rises to the condensation section under the pressure difference, and liquefies and releases heat at the condensation section. The released heat can be naturally dissipated to the air or accelerated by other structures (such as a fan). The liquefied medium returns to the evaporation section at the bottom of the heat pipe 41 under the action of gravity and capillary pores, forming a heat dissipation cycle of “vaporization heat absorption-liquidization heat release”. Heat is continuously conducted away to achieve the effect of rapidly cooling the mainboard 3.
[0041] The heat pipe 41 of the embodiment of the application is vertically arranged on the mainboard 3 along the thickness direction Y of the mainboard 3. Compared with the horizontal placement of the heat pipe 41, the path of the phase change medium liquid in the capillary tube of the heat pipe 41 is shorter when it vaporizes. This is conducive to the rapid vaporization and upward movement of the phase change medium liquid to absorb the heat emitted by the functional devices below the heat pipe 41, thereby improving the heat dissipation efficiency.
[0042] It can be understood that the shell 2 can have other structures in addition to being distributed in two parts along the thickness direction Y of the mainboard 3. For example, the shell 2 includes a left shell and a right shell distributed along the thickness direction Y perpendicular to the mainboard 3. The left shell and the right shell each have a recessed receiving space, and the left shell and the right shell form an accommodation cavity. In the embodiment, as shown in Figure 2 The shell 2 includes an upper shell 21 and a lower shell 22, the upper shell 21 and the lower shell 22 are distributed along the thickness direction Y of the mainboard 3 and connected, and the upper shell 21 and the lower shell 22 each have a recessed receiving space, and the upper shell 21 and the lower shell 22 form an accommodation cavity 201.
[0043] In some embodiments, as Figures 1-3As shown, the upper shell 21 is provided with a plurality of heat dissipation holes 202 in communication with the accommodating cavity 201, and the plurality of heat dissipation holes 202 are distributed at the four sides of the upper shell 21. In this way, the heat generated by the main board 3 located in the accommodating cavity 201 can be dissipated through the plurality of heat dissipation holes 202, thereby reducing the risk of the auxiliary driving controller 1 being too high in temperature. The lower shell 22 is provided with a plurality of openings 203 for the partial devices of the main board 3 to extend out.
[0044] In some embodiments, as shown, the main board 3 comprises a board body 31, a connector 33 and a chip 32, the board body 31 is located in the accommodating cavity 201, the connector 33 is connected to the board body 31 and partially extends out of the accommodating cavity 201, and the chip 32 is arranged on the board body 31 and abuts against the heat pipe 41. In this way, the heat generated by the chip 32 during operation can be transferred to the heat pipe 41, thereby avoiding the chip 32 being too high in working temperature. Figures 4-5
[0045] It can be understood that the chip 32 has different classifications according to its functions, such as a computing power chip 32, an MCU or others. In addition to the above-mentioned structures, the main board 3 can also comprise other electrical elements, such as resistors, capacitors and the like. As shown, Figure 5
[0046] It should be noted that the number of heat pipes 41 can be set as needed, and the heat pipes 41 can abut against the chip 32 with a larger heat generation or other electrical elements on the board body 31, and the specific setting can be made as needed. In this embodiment, in order to improve the heat dissipation effect, the heat pipe 41 abuts against the chip 32 with a larger heat generation, and a heat-conducting medium (such as heat-conducting gel, heat-conducting silicone and the like) with high heat-conducting performance can be coated between the heat pipe 41 and the chip 32 to reduce the thermal resistance and improve the heat conduction efficiency. The temperature control member 42 can be in direct contact with the main board 3 or in indirect contact, as long as it can cool down to dissipate heat when the main board 3 exceeds the first working temperature threshold and heat up to heat the main board 3 in a low-temperature environment.
[0047] In some embodiments, the temperature control member 42 is a Peltier element, which is a component made of two different materials according to the Peltier principle. When the positive direction is powered on, one side generates heat and the other side cools down, and when the reverse direction is powered on, the cold side and the hot side are exchanged.
[0048] Peltier principle refers to the DC through two different conductive materials (usually semiconductors or metals) heterojunction, junction zone will be accompanied by non-joule heat absorption or release: the direction of the current changes, the direction of heat absorption / heat release will also be reversed. Its physical nature is the energy transition of carriers (electrons or holes) at the heterojunction interface, which needs to be combined with the potential energy difference of the material. Different materials have different Fermi levels: the Fermi level is the highest energy level occupied by electrons in the material, which directly determines the energy state of the carriers. When two materials form a junction, the carriers will migrate from the material with a high Fermi level to the material with a low Fermi level to achieve energy balance. There are two cases of energy exchange: (1) for the heat absorption end: if the carrier jumps from the "low potential energy material" to the "high potential energy material", it needs to absorb energy from the outside (to overcome the potential difference), resulting in a decrease in the temperature of the junction zone; (2) for the heat release end: if the carrier jumps from the "high potential energy material" to the "low potential energy material", the excess energy is released in the form of heat, resulting in an increase in the temperature of the junction zone.
[0049] It can be understood that the material selection and the working temperature setting of the Peltier element can be adjusted according to the different heat dissipation intensities required by the different power consumptions of the auxiliary driving controller 1. For example, when the auxiliary driving controller 1 with a current power consumption of 100W is working, the temperature can be as high as 100℃, and the reverse power dissipation temperature of the Peltier element can be set to 70℃. When the power consumption of the auxiliary driving controller 1 is higher, the working temperature can be as high as 150℃, and the reverse power dissipation temperature of the Peltier element can be set to 80℃ or even 100℃.
[0050] It should be understood that the temperature control member 42 can be other structures in addition to the Peltier element, as long as it can transfer heat and cool the mainboard 3 according to the scene needs.
[0051] In some embodiments, as shown in Figure 5 The heat dissipation assembly 4 further includes a heat-conducting filler 43, which is arranged in the accommodating cavity 201 and abuts against the mainboard 3. The heat-conducting filler 43 is used to conduct the heat emitted by the mainboard 3, so as to play a role in dissipating heat for the mainboard 3. In this embodiment, the heat-conducting filler 43 is provided with at least one first mounting opening 431 and at least one second mounting opening 432. One heat pipe 41 is arranged in one first mounting opening 431, and one temperature control member 42 is arranged in one second mounting opening 432. In this way, the first mounting opening 431 and the second mounting opening 432 can fix the heat pipe 41 and the temperature control member 42, and the heat absorbed by the heat pipe 41 can be directly diffused outward through the first mounting opening 431, which is conducive to improving the heat dissipation efficiency.
[0052] It can be understood that the shape of the first mounting hole 431 is similar to the shape of the heat pipe 41, when the heat pipe 41 is a circular heat pipe 41, then the shape of the first mounting hole 431 is a circular hole. When the heat pipe 41 is a square heat pipe 41, then the shape of the first mounting hole 431 is a square shape. Similarly, the shape of the second mounting hole 432 is similar to the shape of the temperature control piece 42, for example, when the shape of the temperature control piece 42 is a square, then the shape of the second mounting hole 432 is a square shape.
[0053] The heat-conducting filling piece 43 can be heat-conducting silica gel, heat-conducting mud or heat-conducting gel, and of course can be other shapes, which can be selected according to needs, as long as heat conduction can be achieved. Of course, in order to avoid short circuit when the heat-conducting filling piece 43 contacts the components on the mainboard 3, the heat-conducting filling piece 43 needs to have insulation performance.
[0054] In some embodiments, as shown in Figure 5 The auxiliary driving controller 1 also includes a sealing partition plate 5, which is accommodated in the accommodating cavity 201 and located on the side of the heat-conducting filling piece 43 away from the mainboard 3. The sealing partition plate 5 is provided with at least one first avoiding hole 501, and the heat pipe 41 passes through the first avoiding hole 501 and is exposed on the side of the sealing partition plate 5 away from the mainboard 3. That is, the end of the heat pipe 41 away from the mainboard 3 is exposed to the sealing partition plate 5 through the first avoiding hole 501, so that the phase change medium in the end of the heat pipe 41 away from the mainboard 3 can be liquefied in time to release heat, thereby achieving the purpose of heat dissipation. Moreover, the sealing partition plate 5 abuts against the heat-conducting filling piece 43, and the sealing partition plate 5 can absorb the heat transferred by the heat-conducting filling piece 43, thereby playing a role in heat dissipation.
[0055] It can be understood that the shape of the first avoiding hole 501 is similar to the shape of the heat pipe 41, that is, the shape of the first avoiding hole 501 changes with the shape of the heat pipe 41, for example, when the heat pipe 41 is a circular heat pipe 41, then the shape of the first avoiding hole 501 is a circular hole. When the heat pipe 41 is a square heat pipe 41, then the shape of the first avoiding hole 501 is a square shape. In this embodiment, there are at least two heat pipes 41, at least two first avoiding holes 501, at least one heat pipe 41 is a circular heat pipe 41, at least one heat pipe 41 is a square heat pipe 41, at least one first avoiding hole 501 is a square avoiding hole, and at least one first avoiding hole 501 is a circular avoiding hole. One circular heat pipe 41 is arranged in one circular avoiding hole, and one square heat pipe 41 is arranged in one square avoiding hole.
[0056] It should be noted that the first avoiding port 501 and the heat pipe 41 need to be sealed, that is, the gap between the first avoiding port 501 and the outer wall surface of the heat pipe 41 needs to be filled to avoid liquid or dust entering the heat-conducting filler 43 through the first avoiding port 501 and falling on the mainboard 3, thereby affecting the normal work of the mainboard 3. In the embodiment, the gap between the first avoiding port 501 and the heat pipe 41 is filled with sealant.
[0057] In some embodiments, as shown in Figure 5 The sealing partition plate 5 is also provided with at least one second avoiding port 502, and one second avoiding port 502 is used to expose one temperature control member 42, so that when one side of the temperature control member 42 faces the mainboard 3 to perform refrigeration, the other side of the temperature control member 42 away from the mainboard 3 can dissipate heat to the side of the sealing partition plate 5 away from the heat-conducting filler 43 through the second avoiding port 502, so as to reduce the adverse effects on the mainboard 3.
[0058] Similarly, the second avoiding port 502 and the temperature control member 42 need to be sealed, that is, the gap between the second avoiding port 502 and the outer wall surface of the temperature control member 42 needs to be filled to avoid liquid or dust entering the heat-conducting filler 43 through the second avoiding port 502 and falling on the mainboard 3, thereby affecting the normal work of the mainboard 3. In the embodiment, the gap between the second avoiding port 502 and the temperature control member 42 is filled with sealant.
[0059] It can be understood that, in order to facilitate installation, a plurality of first avoiding ports 501 need to be distributed and arranged at positions where the heat-conducting filler 43 is located corresponding to a plurality of first mounting ports 431, and a plurality of second avoiding ports 502 need to be distributed and arranged at positions where the heat-conducting filler 43 is located corresponding to a plurality of second mounting ports 432, that is, along the thickness direction Y of the mainboard 3, the first avoiding port 501 is located directly above the first mounting port 431, and the second avoiding port 502 is located directly above the second mounting port 432.
[0060] In some embodiments, as shown in Figure 5As shown, the shell 2 is provided with an air inlet 204 in communication with the accommodating cavity 201, and the auxiliary driving controller 1 further comprises an air supply member (not shown in the figure), which is installed on the shell 2 and located at the air inlet 204, the air inlet end of the air supply member faces the air inlet 204, and the air outlet end of the air supply member faces the sealing partition plate 5, and the air supply member is used for heat dissipation of the exposed part of the heat pipe 41. In this way, the air supply member can accelerate the heat dissipation of the heat pipe 41, compared with the natural heat dissipation mode of the heat pipe 41, which is conducive to improving the heat dissipation efficiency. Moreover, the air blown by the air supply member to the sealing partition plate 5 can also act on the temperature control member 42, which is conducive to the rapid dissipation of the heat emitted by the temperature control member 42, reduces the risk of heat accumulation on the side of the sealing partition plate 5 away from the main board 3, and is conducive to improving the stability of the auxiliary driving controller 1. In the embodiment, the air supply member is a fan and is located in the accommodating cavity 201, and the number of air inlets 204 is two, and the number of fans is correspondingly provided with two.
[0061] It can be understood that when the air supply member blows air to the sealing partition plate 5, dust in the air will be blown to the sealing plate, and in order to avoid the dust entering the main board 3 through the gap between the sealing partition plate 5 and the shell 2, causing the risk of short circuit of the main board 3, the four sides adjacent to the sealing partition plate 5 and the shell 2 need to be glued to isolate the space on the side of the sealing partition plate 5 away from the main board 3 from the space where the main board 3 is located, which is conducive to improving the stability of the main board 3.
[0062] It can be understood that the above-mentioned temperature control member 42 and air supply member can be connected to the main board 3 by a cable, so that the external power supply supplies power to the main board 3 at the same time. The temperature control member 42 and the air supply member are powered. Of course, the above-mentioned temperature control member 42 and air supply member can also be directly connected to the external power supply by a cable, which can be set as needed.
[0063] It should be noted that the number of heat dissipation assemblies 4 is not limited to the case shown in the group Figures 4-5 The specific number can be appropriately increased according to the power consumption of the auxiliary driving controller 1. For example, when the power consumption of the auxiliary driving controller 1 exceeds 300w, the chips 32 on the main board 3 can be arranged on the opposite end faces of the board body 31, and the heat dissipation assemblies 4, i.e. the heat-conducting filling members 43, the heat pipes 41 and the temperature control members 42, are arranged on the opposite end faces of the board body 31, so as to dissipate heat from the chips 32 on the opposite end faces of the board body 31. Moreover, in order to improve the heat dissipation efficiency, the other end face of the board body 31 can also be provided with a sealing partition plate 5 and an air supply member. It should be understood that the heat pipe 41 located at the lower end of the board body 31 relies on the capillary force to form the circulation of the phase change medium. In some embodiments, the auxiliary driving controller 1 can also be provided with a liquid cooling structure, which adopts the existing structure, which will not be described here. However, it should be noted that the specific setting of the liquid cooling structure cannot hinder the normal work of the heat pipe 41.
