All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of an operation method of electrical tuning provided in an embodiment of the present invention, and as shown in fig. 1, the method of the embodiment includes:
s101, arranging a temperature sensor below the circuit board, and enabling the temperature sensor to abut against the inner surface of the heat conducting shell.

The electric tuning in the embodiment comprises a capacitor, a circuit board and a heat conducting shell; the capacitor is carried on the circuit board and is electrically connected with the circuit board, and the circuit board is accommodated in the heat-conducting shell; at least one containing groove is formed in the inner surface of the heat conducting shell, and at least part of the capacitor is contained in the containing groove, so that heat of the capacitor is transferred to the heat conducting shell. That is, electricity is transferred and is included the casing, and this casing is heat conduction casing, and this heat conduction casing's inside can form an accommodation space, can hold the circuit board in this accommodation space, and the last electric capacity that bears of circuit board, consequently, the electric capacity also sets up in heat conduction casing. In addition, at least one accommodating groove is formed in the inner surface of the interior of the heat conducting shell, at least part of the capacitors are accommodated in the accommodating grooves, and if the number of the capacitors is multiple, the capacitors can be accommodated in the same accommodating groove, or different capacitors can be accommodated in different accommodating grooves. Because the capacitor is accommodated in the accommodating groove in the inner surface of the heat-conducting shell, the capacitor is equivalently in direct contact with the inner surface of the heat-conducting shell. And the heat conduction casing has the heat conduction function to the area of contact of storage tank and electric capacity is big, so the heat of electric capacity can transmit to the internal surface of heat conduction casing fast on, because the heat of electric capacity can transmit to the internal surface of heat conduction casing fast, so the temperature of the internal surface of heat conduction casing is very close to the temperature of electric capacity, and the temperature of the internal surface of heat conduction casing that detects this moment can regard as the temperature of electric capacity.
Therefore, this embodiment configures temperature sensor in circuit board below for this temperature sensor butt is on the internal surface of heat conduction casing, thereby temperature sensor fixes to between the internal surface of heat conduction casing and the circuit board, and, the temperature sensor butt is on a face of internal surface, so temperature sensor's fastness in the electricity accent is better, and is more stable, and the operation process of installing temperature sensor is convenient moreover. Since the temperature sensor is in direct contact with the inner surface of the heat conducting shell, the temperature sensor can accurately detect the temperature of the inner surface of the heat conducting shell in real time, and the embodiment can acquire the temperature on the inner surface of the heat conducting shell through the temperature sensor, wherein the temperature on the inner surface is equivalent to the temperature of the capacitor, and then the embodiment controls the electric regulation according to the temperature on the inner surface (equivalent to the temperature of the capacitor).
Optionally, according to the temperature, a feasible implementation manner of controlling the work of the electrical tuning is as follows: and determining whether the temperature detected by the temperature sensor is higher than a preset temperature, and when the temperature detected by the temperature sensor is higher than the preset temperature, indicating that the temperature of the capacitor is too high, so as to avoid the temperature of the capacitor from continuously rising, reducing the power of the electric regulator and controlling the electric regulator to stop working, thereby reducing the temperature of the capacitor. When the temperature detected by the temperature sensor is less than or equal to the preset temperature, the temperature of the capacitor is not high, and at the moment, the capacitor does not need to be cooled, and the electric regulation is continuously controlled to keep working. Optionally, the preset temperature is greater than or equal to 120 ℃.
In this embodiment, because the internal surface of the heat conduction casing that transfers electrically is provided with at least one storage tank, and the electric capacity holding is in the storage tank, so the heat of electric capacity can transmit the internal surface to the heat conduction casing fast, therefore, with the temperature sensor butt on the internal surface of heat conduction casing, the temperature that the temperature sensor detected is very close to the temperature of electric capacity, consequently, the temperature rate of accuracy that this embodiment acquireed the electric capacity through this temperature sensor is high, the work of transferring electrically under the temperature of accurate electric capacity is controlled, can avoid the emergence of the electric capacity life-span to reduce fast and the inefficacy phenomenon that the mud explosion leads to.
Fig. 2 is a schematic structural diagram of an electrical tilt according to an embodiment of the present invention, and as shown in fig. 2, the electrical tilt 200 according to this embodiment may include: a capacitor 210, a temperature sensor 220, a controller 230, a circuit board 240, and a thermally conductive housing 250.
The capacitor 210, the temperature sensor 220, and the controller 230 are electrically connected to the circuit board 240; the capacitor 210 is carried on the circuit board 240, the controller 230 is disposed on the circuit board 240, the temperature sensor 220 is fixed under the circuit board 240, and the circuit board 240 is accommodated in the heat conductive housing 250.
At least one receiving groove 260 is disposed on an inner surface 251 of the heat conductive housing 250, and at least a portion of the capacitor 210 is received in the receiving groove 260, so that heat of the capacitor 210 is transferred to the heat conductive housing 250.
The temperature sensor 220 abuts against the inner surface 251 of the heat conductive housing 250, and is used for sensing the temperature on the inner surface 251 and outputting the temperature to the controller 230.
The controller 230 is in communication connection with the temperature sensor 220, and is configured to control the operation of the electronic tilt 210 according to the temperature.
Optionally, the controller 230 is specifically configured to, when the temperature is greater than a preset temperature, reduce the power of the electrical tilt 200 or control the electrical tilt 200 to stop working.
Optionally, the preset temperature is greater than or equal to 120 ℃.
The electrical tilt of this embodiment may be used to implement the technical solution of the above method embodiment of the present invention, and the implementation principle and technical effect are similar, which are not described herein again.
Fig. 3 is a schematic structural diagram of an electronic tilt according to a second embodiment of the present invention, where in fig. 3, a heat-conducting housing 250 includes a first housing 252 and a second housing 253 as an example, and fig. 4 is a schematic cross-sectional diagram of the electronic tilt according to the second embodiment of the present invention, as shown in fig. 3 and fig. 4, in this embodiment, on the basis of the electronic tilt scheme shown in fig. 2, a boss 270 is disposed on an inner surface 251 of the heat-conducting housing 250, and the boss 270 is located outside an end portion 261 of the accommodating groove 260. And a temperature sensor 220 abutting against the boss 270.
In this embodiment, in order to avoid the phenomenon that the height of the temperature sensor 220 may be insufficient, so that the temperature sensor 220 cannot directly abut against the inner surface 251 of the heat conducting shell 250, and the temperature detected by the temperature sensor 220 is not accurate enough. In one possible implementation, the present embodiment may fill a heat conducting medium between the temperature sensor 220 and the inner surface 251.
In another possible implementation manner, the present embodiment provides a boss 270 on the inner surface 251 of the heat conducting shell 250, and the boss 270 protrudes from the inner surface 251 toward the inside of the heat conducting shell 250 to a certain height, so that the temperature sensor 220 can abut on the boss 270. The protrusion 270 protrudes from the inner surface 251, so that the temperature of the inner surface 251 can be rapidly transmitted to the protrusion 270, and the temperature of the protrusion 270 detected by the temperature sensor 220 is very close to the temperature of the capacitor 210, thereby improving the accuracy of detecting the temperature of the capacitor 210. Optionally, the boss 270 is a metal boss 270, which facilitates rapid heat transfer to the boss 270.
Optionally, the temperature sensor 220 abuts on the upper surface 271 of the boss 270. Since the upper surface 271 of the boss 270 faces the lower surface of the circuit board 240, the temperature sensor 220 abuts on the upper surface 271 of the boss 270, and the temperature sensor 220 is sandwiched between the lower side of the circuit board and the upper side of the boss 270, thereby further fixing the position of the temperature sensor 220.
Optionally, the temperature sensor 220 is attached to the boss 270 through a heat conducting medium. In this embodiment, there may be a certain gap between the temperature sensor 220 and the boss 270 because the height of the temperature sensor 220 is still insufficient and the temperature sensor cannot be directly abutted to the boss 270, and the gap reduces the accuracy of the temperature detected by the temperature sensor 220, so that the heat-conducting medium is filled between the temperature sensor 220 and the boss 270 in this embodiment, so that the temperature sensor 220 is attached to the boss 270 through the heat-conducting medium, and the abutment of the temperature sensor 220 to the boss 270 is realized.
Optionally, a gap 280 is reserved between the boss 270 and the end 261 of the receiving groove 260. The gap 280 provides a clearance space, since the capacitor 210 is not a regular cylinder, and the end of the capacitor has a ring-shaped protrusion, which is just placed in the gap, so that the capacitor 210 is just laid down in the receiving groove 260.
Optionally, two steps 290 are further disposed on the inner surface 251 of the heat conducting shell 250, an accommodating space is formed between the steps 290, and the at least one accommodating groove 260 is located in the accommodating space. Since the receiving groove 260 is located between the two steps 290 and is limited in the receiving space, the heat transferred from the capacitor 210 to the receiving groove 260 is not easily dissipated outward, and the temperature of the capacitor 210 is accurately transferred to the inner surface 251 of the heat conductive housing 250.
Optionally, the step 290 is integrally formed with the heat conducting shell 250. Since the step 290 is a part of the heat conductive housing 250, the heat of the capacitor 210 is transferred to the step 290, which is equivalent to the heat conductive housing 250, thereby avoiding the heat loss of the capacitor 210.
Optionally, the boss 270 is disposed near one end of the two steps 290.
Optionally, the capacitor 210 is disposed in the accommodating groove 260 in a lying manner. Since the capacitor 210 is generally cylindrical, the capacitor 210 is disposed in the receiving groove 260 in a lying manner, so as to further increase a contact area between the capacitor 210 and the receiving groove 260, and further accelerate heat transfer of the capacitor 210 to the receiving groove 260.
Optionally, a curved groove wall 262 contacting the outer wall 211 of the capacitor 210 is disposed in the receiving groove 260. Since the outer wall 211 of the capacitor 210 is curved, the wall of the accommodating groove 260 is also curved, and the degree of matching between the curved surface and the curved surface is high, so that the contact area between the capacitor 210 and the accommodating groove 260 is further increased, and the heat transfer of the capacitor 210 to the inner wall of the accommodating groove 260 is further accelerated.
Optionally, the curved slot wall 262 conforms to the shape of the outer wall 211. In this embodiment, the curved groove wall 262 is matched with the outer wall 211 in shape, which means that the curvature of the outer wall 211 of the capacitor 210 is the same as the curvature of the curved groove wall 262 of the accommodating groove 260, so that the contact gap between the capacitor 210 and the accommodating groove 260 can be further reduced, the contact area between the capacitor 210 and the accommodating groove 260 is enlarged, and the heat transfer of the capacitor 210 to the inner wall of the accommodating groove 260 is accelerated.
Optionally, a heat conducting medium is filled between the curved groove wall 262 and the outer wall 211 of the capacitor 210. In this embodiment, because a gap exists between the curved groove wall 262 and the outer wall 211 of the capacitor 210 more or less during the actual manufacturing process, in this embodiment, a heat-conducting medium is filled between the curved groove wall 262 and the outer wall 211 of the capacitor 210, so that the curved groove wall 262 and the outer wall 211 of the capacitor 210 achieve the effect of completing the matching, and the contact between the outer wall 211 of the capacitor 210 and the curved groove wall 262 is better, so that the heat of the capacitor 210 can be quickly transferred to the curved groove wall 262 of the accommodating groove 260, thereby accelerating the heat transfer of the capacitor 210 to the inner surface 251 of the heat-conducting housing 250.
Optionally, two curved groove walls 262 in the accommodating groove 260 are provided, and the two curved groove walls 262 are connected by a partial plane of the inner surface 251 of the heat conducting shell 250.
Optionally, a heat conducting medium is filled between the partial plane and the capacitor 210. Since the outer wall 211 of the capacitor 210 is a curved surface, a certain gap exists between the capacitor and a partial plane, in order to enable the capacitor 210 to be well matched with the partial plane, in this embodiment, a heat conducting medium is filled between the partial plane and the capacitor 210, and the filled heat conducting medium can enable heat of the capacitor 210 to be rapidly transferred to the inner surface 251 of the heat conducting shell 250.
Optionally, the number of the receiving grooves 260 is the same as the number of the capacitors 210. Since different capacitors 210 are disposed in different receiving grooves 260, the contact area between the capacitors 210 and the receiving grooves 260 is increased, which is beneficial to transferring the heat of the capacitors 210 to the inner surface 251 of the heat conductive housing 250. Fig. 3 and 4 show that the number of the capacitors 210 is two, and the number of the accommodating grooves 260 is also two.
Optionally, every two adjacent curved groove walls 262 of the accommodating groove 260 are connected back to back. In this embodiment, the adjacent curved groove walls 262 of the receiving groove 260 are connected seamlessly, so that the heat of the receiving groove 260 is favorably transferred to the inner surface 251 of the heat conductive shell 250.
Optionally, the heat conducting medium is a liquid or paste heat conducting medium, and a heat conducting layer is formed after the heat conducting medium is dried.
Optionally, the heat conducting medium comprises at least one of: the heat conduction silicone grease, the heat conduction silicone, the anodic oxide film and the phase change heat conduction medium.
Optionally, the heat conducting housing 250 is a metal housing. The heat conductive housing 250 is a metal housing, which facilitates rapid heat transfer from the capacitor 210 to the heat conductive housing 250 due to good thermal conductivity of the metal housing.
