[0016] 3. Beneficial Effects Compared with the prior art, the advantages of this invention are: This solution utilizes a heat dissipation mechanism that, when the power regulation module generates more heat and vibrates, can use an elastic support component to squeeze the heat-conducting fluid inside the heat-conducting copper pipe. This squeezing accelerates the circulation speed of the heat-conducting fluid, thereby improving the heat dissipation effect.

[0017] This solution utilizes an auxiliary mechanism that drives the transmission mechanism to rotate during the operation of the elastic support component. Combined with the blower shroud, it can blow away the heat absorbed by the heat dissipation fins, thereby further improving the heat dissipation effect. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example 1: Please see Figure 1-4A mechanical support and heat dissipation device for an integrated power regulation module includes a main body 1, a heat dissipation mechanism 2, and an auxiliary mechanism 3. The main body 1 includes a support base 11, a mounting groove 12 formed on the top of the support base 11, and a power regulation module 13 installed in the inner cavity of the mounting groove 12. The power regulation module 13 can be installed by setting the mounting groove 12 on the support base 11. The heat dissipation mechanism 2 includes a base plate 21, an elastic support member 22 set on the inner side of the support base 11 and the base plate 21, and a heat dissipation member 23 installed on the bottom of the support base 11. A pressing member 24 is set between the elastic support member 22 and the heat dissipation member 23. The elastic support member 22 can play a shock absorption and buffering role when the power regulation module 13 vibrates due to increased heat. The cooperation between the base plate 21 and the elastic support member 22 can support the main body 1. The heat dissipation member 23 can dissipate heat from the main body 1. The cooperation between the heat dissipation member 23 and the pressing member 24 can accelerate the heat dissipation efficiency of the heat dissipation member 23.

[0024] The number of elastic support components 22 is four, and the four elastic support components 22 are respectively set at the four corners of the lower surface of the support base 11; by setting four elastic support components 22, the stability of the support base 11 when supported can be increased.

[0025] Furthermore, the elastic support component 22 includes a cavity plate 221 fixedly installed on the top of the base plate 21, and a support rod 222 vertically penetrating the top of the cavity plate 221. The cavity plate 221 has an upper pressure plate 223, a lower pressure plate 224, and a return spring 225 arranged sequentially from top to bottom. The lower pressure plate 224 is a titanium alloy spring. The two ends of the support rod 222 are fixedly connected to the bottom of the support base 11 and the top of the upper pressure plate 223, respectively. The two ends of the lower pressure plate 224 are fixedly connected to the bottom of the upper pressure plate 223 and the top of the return spring 225, respectively. The surface of the upper pressure plate 223 is slidably connected to the inner wall of the cavity plate 221. When the power adjustment module 13 vibrates, the support rod 222 can be subjected to a downward impact force under the transmission of the support base 11. Under the connection of the upper pressure plate 223, the lower pressure plate 224 can be compressed. Through the mutual cancellation of forces, a shock absorption and buffering effect can be achieved.

[0026] Furthermore, the heat dissipation component 23 includes heat dissipation fins 231 disposed at the bottom of the support base 11, and a heat-conducting copper pipe 232 connected to the heat dissipation fins 231. A connecting block 233 is installed between the heat dissipation fins 231 and the support base 11. The heat-conducting copper pipe 232 passes through the support base 11 and is embedded inside the power regulation module 13. The heat-conducting copper pipe 232 is filled with a heat-conducting fluid, which is an aqueous solution of ethylene glycol or a heat-conducting silicone oil. By the flow of the heat-conducting fluid in the heat-conducting copper pipe 232, the heat generated by the power regulation module 13 can be absorbed. When the heat-conducting fluid moves to the position of the heat dissipation fins 231, the heat of the heat-conducting fluid in the heat-conducting copper pipe 232 can be absorbed by the heat dissipation fins 231, thereby achieving the effect of heat exchange. By the continuous flow of the heat-conducting fluid in the heat-conducting copper pipe 232, the heat dissipation of the power regulation module 13 can be achieved.

[0027] More preferably, the extrusion component 24 includes a first connecting pipe 241 and a second connecting pipe 242 respectively installed at both ends of the heat-conducting copper pipe 232, and two connecting pipes 243 connected to the first connecting pipe 241 and the second connecting pipe 242. A rubber buffer pad 244 is installed at the bottom of the inner cavity of the cavity plate 221. A groove 245 is formed inside the rubber buffer pad 244. An outer connecting pipe 246 is installed on the side of the cavity plate 221. The bottom of the outer connecting pipe 246 passes through the inside of the groove 245. An movable groove 247 is formed on the side of the cavity plate 221 relative to the longitudinal movement trajectory of the outer connecting pipe 246. There are four outer connecting pipes 246. One end of two adjacent outer connecting pipes 246 is fixedly connected to both ends of the connecting pipes 243 respectively. When the power is adjusted... When the heat generated by module 13 increases and is accompanied by significant vibration, the return spring 225 can move downward through the connection of support rod 222, upper pressure plate 223 and lower pressure plate 224, and squeeze the rubber buffer pad 244. When the rubber buffer pad 244 is squeezed, it deforms, and the internal pressure increases. At this time, the heat-conducting liquid inside the rubber buffer pad 244 enters the connecting pipe 243 through the outer pipe 246, and then flows into the inlet and outlet of the heat-conducting copper pipe 232 through the first connecting pipe 241 and the second connecting pipe 242 respectively. By pressurizing both ends of the heat-conducting copper pipe 232, the flow rate of the heat-conducting liquid inside it can be accelerated, thereby improving the heat exchange efficiency and thus improving the heat dissipation effect of the power regulation module 13. It should be noted that when the power adjustment module 13 vibrates, the heat sink 231 and the heat-conducting copper pipe 232 move downward synchronously with the support base 11. When the rubber buffer pad 244 is squeezed and deformed, the outer pipe 246 moves downward synchronously with the rubber buffer pad 244 and moves in the movable groove 247. At the same time, it drives the connecting pipe 243 and the rubber buffer pad 244 to move synchronously. By making the movement amplitude of each structure the same, the vibration can avoid interference between the structures. It should also be noted that two one-way valves 2421 are installed at both ends of the heat-conducting copper pipe 232 at the positions where it connects to the first connecting pipe 241 and the second connecting pipe 242, so as to ensure the circulation direction of the coolant in the heat-conducting copper pipe 232 and prevent backflow. Furthermore, when the lower pressure plate 224 moves downward to its maximum position and then resets, the reset spring 225 moves upward. At this time, the rubber buffer pad 244 moves upward and generates negative pressure. Under the action of the outer pipe 246, the connecting pipe 243, the second connecting pipe 242, and the first connecting pipe 241, the heat transfer fluid in the heat-conducting copper pipe 232 can flow back. Under the restriction of the one-way valve 2421, the flow rate of the heat transfer fluid in the heat-conducting copper pipe 232 can be further accelerated, thereby achieving the purpose of continuously enhancing the heat exchange effect.

[0028] Furthermore, the inner wall of the groove 245 is provided with a high-density nitrile rubber inner lining layer 248, and the connection port of the outer pipe 246 and the rubber buffer pad 244 is pre-embedded with a metal insert 249. The connection between the metal insert 249 and the outer pipe 246 is wrapped with high-temperature resistant polytetrafluoroethylene raw material tape. By setting the high-density nitrile rubber inner lining layer 248, the sealing performance of the groove 245 can be increased to avoid leakage of heat transfer fluid. By setting the metal insert 249 and the high-temperature resistant polytetrafluoroethylene raw material tape, the sealing performance between the groove 245 and the outer pipe 246 can be increased.

[0029] Specifically, the heat generated by the power regulation module 13 during operation is rapidly absorbed by the ethylene glycol aqueous solution or thermally conductive silicone oil embedded in the heat-conducting copper pipe 232. The heat is then transferred to the heat dissipation fins 231 at the bottom of the support base 11 via the flow of the heat-conducting fluid, where initial heat exchange is completed through the contact between the fins and the air. When the module's operating power increases, the heat generation increases, and vibration occurs, the support base 11 transmits the vibration impact force to the support rods 222 at the four corners of the bottom, thereby causing the upper pressure plate 223 inside the cavity plate 221 to move downwards synchronously, compressing the lower reset spring 225. The elastic deformation of the spring is used to achieve shock absorption. During this process, the lower pressure plate 224 simultaneously squeezes the cavity plate 221. The rubber buffer pad 244 at the bottom of the tube 21 causes the internal groove 245 to deform and the pressure to increase. Under pressure, the heat-conducting liquid in the groove 245 flows into the connecting pipe 243 through the outer pipe 246, and then flows into both ends of the heat-conducting copper pipe 232 through the first connecting pipe 241 and the second connecting pipe 242 respectively. The one-way valves 2421 installed at both ends of the heat-conducting copper pipe 232 can effectively ensure the one-way flow of the heat-conducting liquid and avoid backflow. The pressurization directly accelerates the circulation rate of the heat-conducting liquid in the pipe. When the return spring 225 rebounds, the rubber buffer pad 244 returns to its original shape and generates negative pressure, which further guides the heat-conducting liquid to continue to flow, thereby continuously enhancing the heat exchange efficiency and realizing adaptive heat dissipation.

[0030] Example 2: This embodiment 2 is an improvement based on embodiment 1. The difference between it and embodiment 1 is that... (Please refer to...) Figure 1 , Figure 5 and Figure 6 It also includes an auxiliary mechanism 3, which includes a connecting plate 31 mounted on the elastic support component 22 and a blower shroud 32 mounted on the top of the base plate 21. The blower shroud 32 and the heat dissipation component 23 are correspondingly arranged, and a transmission mechanism 33 is provided between the connecting plate 31 and the blower shroud 32. By setting the connecting plate 31, it can move synchronously when the support rod 222 moves downward. Under the transmission of the transmission mechanism 33, airflow can be generated. Under the guidance of the blower shroud 32, the heat absorbed on the heat dissipation fins 231 can be quickly dissipated, thereby improving the heat dissipation effect of the power adjustment module 13.

[0031] The transmission mechanism 33 includes a transmission plate 331 fixedly connected to the bottom of the connecting plate 31, and a rotating shaft 332 rotatably connected to the blower shroud 32. A gear 333 is fixedly sleeved on the surface of the rotating shaft 332. Multiple teeth 334 are equidistantly arranged on the side of the transmission plate 331 relative to the gear 333. One end of the rotating shaft 332 passes through the interior of the blower shroud 32. Multiple fan blades 335 are equidistantly installed on the surface of the end of the rotating shaft 332 away from the gear 333. When the support rod 222 drives the blower shroud 32 to move downward, it can drive the transmission plate 331 to move downward synchronously. Under the action of the teeth 334, it can mesh with the gear 333 for transmission, thereby causing the rotating shaft 332 to rotate. When the rotating shaft 332 rotates, the fan blades 335 rotate to generate cooling airflow, thereby blowing away the heat on the heat dissipation fins 231, improving its heat exchange performance, and thus improving the heat dissipation effect of the power adjustment module 13.

[0032] The connecting plate 31 is mounted on the surfaces of two adjacent support rods 222 at both ends, and the inner cavity of the blower shroud 32 is V-shaped. The V-shaped shape of the blower shroud 32 can achieve the effect of cooling all the heat dissipation fins on the heat dissipation fins 231. The surface of the transmission plate 331 is provided with a guide groove 336, and a guide block 337 is slidably fitted inside the guide groove 336. The guide block 337 is fixedly installed on the surface of the blower shroud 32. By setting the guide groove 336 and the guide block 337, the movement direction of the transmission plate 331 can be limited to avoid the auxiliary mechanism 3 from failing to work properly due to deviation in its direction.

[0033] It should also be noted that the connecting plate 31, transmission plate 331, gear 333 and tooth 334 are all made of aluminum alloy, the rotating shaft 332 is made of carbon fiber composite material, and the fan blade 335 is made of magnesium-aluminum alloy.

[0034] Specifically, when the support rod 222 moves up and down with vibration, it drives the connecting plates 31 at both ends to rise and fall synchronously. The transmission plate 331 at the bottom of the connecting plate 31 also moves linearly. The guide groove 336 on the surface of the transmission plate 331 and the guide block 337 on the blower shroud 32 cooperate with each other to effectively ensure the stability of the movement direction and avoid deviation. During the movement of the transmission plate 331, the teeth 334 on its side will mesh with the gears 333 on the surface of the rotating shaft 332 to convert the linear motion into the rotational motion of the rotating shaft 332. Since one end of the rotating shaft 332 passes through the blower shroud 32 with a V-shaped design and the end is equipped with a fan blade 335, when the rotating shaft 332 rotates, it will drive the fan blade 335 to rotate synchronously and generate cooling airflow. After being guided by the V-shaped blower shroud 32, the airflow can be accurately and comprehensively blown onto the heat dissipation fins 231, quickly removing the heat from the surface of the fins. This forms an efficient synergy with the heat dissipation of the heat transfer fluid circulation, significantly improving the overall heat dissipation effect.

[0035] The rest of the structure is the same as in Implementation 1.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
