Description

Technical Field

[0001] The utility model relates to the technical field of radiators, and in particular to an intelligent control energy-saving water-cooling radiator for a vehicle-mounted electric drive control system. Background Art

[0002] With the rapid progress of new energy technologies and related electrical technologies, electric drive has gradually emerged and quickly occupied a place in mining and tunnel engineering. With its many advantages such as high traction power, smooth starting process, and compact equipment size, it has demonstrated strong adaptability to various slope and load conditions. It is gradually replacing traditional mechanical drive and becoming the new mainstream in the field of mining and tunnel excavation. However, due to the special and complex working environment of mines and underground mining, the reliability of the entire motor drive control system is very high, requiring long life, easy maintenance, and high reliability. The main core components of electric drive are motors and motor controllers, which are the main heat-generating devices. The traditional air-cooled heat dissipation form of core components has low reliability and requires frequent maintenance. It has gradually failed to meet the use needs of high-power electric drive equipment. Therefore, the industry mostly uses high-power water-cooled motors and water-cooled motor controllers as the main drive core equipment, which have the advantages of high power density and high power output.

[0003] However, in order to improve the heat dissipation effect, the existing water-cooled radiator's auxiliary equipment such as fans will generate large energy consumption when running at the same time, which not only increases the operating cost, but also affects the stability of the system. Moreover, since most of the existing water-cooled radiator frames are composed of individual frame plates and fan fixing covers assembled together, the frame is first assembled by assembling the individual frame plates, and then the heat dissipation core is installed inside the frame, and the frame plates are welded to complete the installation of the heat dissipation core. Finally, the fan fixing cover with the individual fans installed inside is installed on the frame to cover the heat dissipation core to complete the assembly of the radiator. When the components and fans on the heat dissipation core fail, not only can the frame not be directly disassembled to repair or replace the components on the heat dissipation core, but the entire fan fixing cover needs to be removed to maintain the fan on it, which is more troublesome, prolongs the maintenance time of the radiator, and reduces the maintenance efficiency of the radiator. Therefore, those skilled in the art provide an intelligent control energy-saving water-cooled radiator for an on-board electric drive control system to solve the problems raised in the above background technology.

[0009] The shock absorbing assembly is arranged on the outer wall of the fixing frame for installation and shock absorption of the water cooling radiator.

[0010] Preferably, grooves are provided on the inner sides of the two end frames, and both ends of the side frames are plugged into the interior of the end frames through the grooves.

[0011] Preferably, a drain outlet for replacing the coolant is provided at the end face of the heat dissipation core between the two water outlets, and threaded joints are provided at the drain outlet, water inlet and water outlet.

In addition, a through opening is opened at the middle position of the end plate of the right-angle fixing seat away from the fixing frame, and a through hole connected to the through opening is opened at the middle position of the two cylindrical shock absorbers, and the extension bolt is arranged on the inner side of the right-angle fixing seat, the extension bolt passes through the two through holes, and the through opening thread is installed on the frame.

[0015] Preferably, the shock-absorbing assembly also includes a rectangular silicone shock-absorbing pad and a U-shaped silicone shock-absorbing pad, wherein the rectangular silicone shock-absorbing pad is installed on the left and right sides of the heat dissipation core and contacts the inner walls of the two side frames, and the U-shaped silicone shock-absorbing pad is snap-fitted and installed at the upper and lower ends of the end frame, and the outer wall of the U-shaped silicone shock-absorbing pad is provided with reinforcing ribs, and the U-shaped silicone shock-absorbing pad contacts the inner wall of the end frame through the reinforcing ribs.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] By arranging two groups of rectangular water channels on the heat dissipation core, when using the radiator for heat dissipation, two water inlet and outlet methods can be used to allow the two groups of rectangular water channels to dissipate heat for the motor and controller respectively, so that the heat dissipation water channels of the motor and motor controller do not affect each other, thereby improving the reliability of the heat dissipation of the motor and motor controller, and ensuring the heat dissipation effect of the motor and motor controller. At the same time, a temperature sensor is used to detect the temperature of the coolant in the heat dissipation core, and the collected coolant temperature information is transmitted to the intelligent controller. The intelligent controller analyzes and processes the coolant temperature data collected by the temperature sensor, and controls the opening and closing and the number of revolutions of the fan body according to the coolant temperature data, so that the number of opening and closing of the fan and the number of revolutions match the actual heat exchange power of the radiator, avoiding the excessive consumption of the battery of the drive system due to the simultaneous operation of each fan on the radiator, which not only reduces the operating cost and achieves the effect of energy saving and environmental protection, but also ensures the stability of the system and its strong practicality.

[0018] By setting up the frame assembly, when maintaining the components on the heat sink core, the fastening bolts can be tightened to remove the fastening bolts from the end frame and the side frame, and then the side frame can be slid to both sides between the two end frames through the grooves to remove the end frame and the side frame outside the heat sink core. The radiator frame outside the heat sink core can be disassembled to expose the heat sink core inside the radiator frame, and the faulty components on the heat sink core can be directly repaired and replaced, avoiding the situation where the radiator frame needs to be cut to remove the heat sink core due to welding, thereby facilitating the maintenance of the radiator.

In addition, the term "including" and any variations thereof are intended to cover non-exclusive inclusions.

[0031] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, an intelligent energy-saving water-cooling radiator for an on-board electric drive control system includes: a frame assembly 1, a heat dissipation assembly 2, a fan assembly 3 and a shock absorption assembly 4, wherein the frame assembly 1 includes two symmetrically distributed end frames 11, and two symmetrically distributed side frames 12 are arranged between the two end frames 11, and the two ends of the two side frames 12 are respectively inserted into the interior of the two end frames 11, and fastening bolts 13 are provided at positions corresponding to the end faces of the end frames 11 and the side frames 12. The fastening bolts 13 pass through the end frames 11 and are threadedly installed in the interior of the side frames 12, and the two end frames 11 and the side frames 12 are spliced ​​to form a fixed frame.

[0032] In one embodiment, when assembling the radiator frame, the two ends of the two side frame plates 12 can be directly inserted into the grooves 111 on the inner sides of the two end frames 11, and then the two side frames 12 can be slid in the grooves 111 to adjust the positions of the two side frames 12. Finally, the fastening bolts 13 are installed at the connection between the end frames 11 and the side frames 12 to limit the positions of the end frames 11 and the side frames 12. The two end frames 11 and the side frames 12 can be assembled into a fixed frame, thereby completing the assembly of the radiator frame. The radiator frame can be disassembled into two end frames 11 and side frames 12, and the end frames 11 and side frames 12 can be transported separately. The radiator frame will not occupy a large transportation space, which avoids the inconvenience of transportation due to the large size of the radiator frame. The structure is simple and disassembly is convenient, which facilitates the subsequent assembly of the radiator.

[0033] The two ends of the side frame plates 12 are then inserted into the grooves 111 on the inner sides of the two end frames 11, and the two side frames 12 are slid in the grooves 111 to adjust the positions of the two side frames 12 so that the two side frames 12 are clamped on both sides of the heat dissipation core 21. Finally, the fastening bolts 13 are tightened to limit the positions of the side frames 12 after the adjustment, and the installation of the heat dissipation core 21 is completed. The radiator frame can be assembled to the outside of the heat dissipation core 21 in an assembled manner, which facilitates the disassembly and assembly of the radiator frame and the heat dissipation core 21, and the faulty components on the heat dissipation core 21 can be directly repaired and replaced, avoiding the situation where the radiator frame needs to be cut to remove the heat dissipation core 21 due to welding, thereby facilitating the maintenance of the radiator.

[0034] In one embodiment, when assembling the radiator frame, the two side frames 12 can be slid in the grooves 111 on the inner sides of the two end frames 11, and the distance between the two side frames 12 can be adjusted so that the distance between the two side frames 12 is adapted to the width of the heat dissipation core 21, which is suitable for the installation of different models of heat dissipation cores 21.

[0035] Combine Figure 1 、 Figure 2 、 Figure 4 、 Figure 8 and Figure 9As shown, the heat dissipation assembly 2 includes a heat dissipation core 21, which is installed inside the fixed frame, and two groups of rectangular water channels 22 are provided inside the heat dissipation core 21. Water inlets and drains are respectively provided at the upper and lower ends of the end face of the heat dissipation core 21 corresponding to the two groups of rectangular water channels 22. Angle valves 24 for opening and closing are installed at the water inlet and drain. The outer walls of the two rectangular water channels 22 are welded with wavy heat dissipation fins 23 for heat dissipation. A temperature sensor 25 for detecting the temperature of the coolant in its inner cavity is provided on the side of the water inlet of the end face of the heat dissipation core 21.

[0036] In one embodiment, when cooling the motor and motor controller in the drive system, the water in the two sets of rectangular water channels 22 can be circulated through the two water inlets and outlets on the front of the heat dissipation core 21, so that the two sets of rectangular water channels 22 and the wavy heat dissipation fins 23 outside thereof can cool the motor and controller in the drive system respectively, and the heat dissipation water paths of the motor and the motor controller will not affect each other, thereby improving the reliability of the heat dissipation of the motor and the motor controller, and ensuring the heat dissipation effect of the motor and the motor controller. Moreover, the components of the heat dissipation core 21 are all arranged on its front, and water pipes and temperature sensors 25 and other components can be directly installed on the front of the heat dissipation core 21, which facilitates on-site installation work.

[0037] In one embodiment, since the heat dissipation core 21 is provided with a temperature sensor 25 for detecting the temperature of the coolant in its inner cavity, when the radiator is in use, the temperature of the coolant in the heat dissipation core 21 can be detected by the temperature sensor 25, and the collected coolant temperature information is transmitted to the intelligent controller, which analyzes and processes the coolant temperature data collected by the temperature sensor 25, and controls the opening and closing and the number of revolutions of the fan body 32 according to the coolant temperature data, so that the number of opening and closing of the fan and the number of revolutions match the actual heat exchange power of the radiator, thereby avoiding the excessive consumption of the power of the drive system battery due to the simultaneous operation of the fans on the radiator, which not only reduces the operating cost and achieves the effect of energy saving and environmental protection, but also ensures the stability of the system and strong practicality.

[0038] In one embodiment, since the drain port, water inlet, and water outlet on the heat dissipation core 21 are all provided with threaded joints 26, the angle valve 24 is installed at the drain port, water inlet, and water outlet through the threaded joint 26. When the radiator is maintained, the drain port, water inlet, and water outlet can be opened and closed by the angle valve 24 to prevent water and coolant in the radiator from leaking, thereby ensuring the stability of the heat dissipation system.

[0039] Combine Figure 1 、 Figure 2 and Figure 5As shown, the fan assembly 3 includes a fixed cover 31, which is installed on one side of the fixed frame and covers the heat dissipation core 21, and the inner cavity of the fixed cover 31 is provided with a cross-guide baffle 33, which divides the inner cavity of the fixed cover 31 into four partitions. The fixed cover 31 and the four partitions are respectively provided with a fan body 32 at the corresponding positions. The fan body 32 is embedded in the back of the fixed cover 31 and is connected to the partitions.

[0040] In one embodiment, when the fan is installed, the fixing cover 31 can be directly installed on one side of the radiator frame to cover the heat dissipation core 21, and then the fan body 32 can be installed in the mounting hole 311 on the back of the fixing cover 31, so that the air outlet of the fan body 32 is located in the inner cavity of the fixing cover 31, and then the fixing bolts 35 at the four corners of the fan body 32 are screwed, and the fixing bolts 35 are passed through the fixing cover 31 and installed on the fixing nuts 34 welded in its inner cavity, and the installation of the fan is completed. This changes the installation method of the fan, and the fan can be directly removed from the back of the fixing cover 31, avoiding the trouble of having to remove the fixing cover 31 to disassemble and maintain the fan, saving a lot of time, and improving the maintenance efficiency of the radiator.

[0041] In one embodiment, when the fan is in use, since the inner cavity of the fixed cover 31 is provided with a cross-guide baffle 33, the cross-guide baffle 33 divides the inner cavity of the fixed cover 31 into four partitions, and the four fan bodies 32 are respectively installed in the four partitions. The wind direction of the fan located in the partition can be guided by the cross-guide baffle 33, thereby improving the use effect of the fan.

[0042] In one embodiment, since the back of the fixed cover 31 is located on one side of the fan body 32 and is provided with a wire binding pile 36 for winding its wiring harness, when the fan is installed on the back of the fixed cover 31, the wiring harness of the fan can be wound around the wire binding pile 36 to prevent the wiring harness from being affected by wind when the fan is running at high speed and being wound into the machine and contacting the fan blades and being damaged, thereby achieving the limitation and protection of the fan wiring harness.

[0043] Combine Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, the shock absorbing assembly 4 is arranged on the outer wall of the fixed frame for the installation and shock absorption of the water-cooled radiator, and the shock absorbing assembly 4 includes a right-angle fixing seat 41, two cylindrical shock absorbers 42 and an extension bolt 43, wherein one side end plate of the right-angle fixing seat 41 is installed on the outer wall of the fixed frame, and the two cylindrical shock absorbers 42 are respectively arranged on the inner and outer sides of the end plate of the right-angle fixing seat 41 away from the fixed frame side, and a through opening 411 is opened at the middle position of the end plate of the right-angle fixing seat 41 away from the fixed frame side, and a through hole 421 connected to the through opening 411 is opened at the middle position of the two cylindrical shock absorbers 42, and the extension bolt 43 is arranged on the inner side of the right-angle fixing seat 41, and the extension bolt 43 passes through the two through holes 421, and the through opening 411 is threadedly installed on the frame.

[0044] In one embodiment, when installing the radiator frame on the vehicle frame, the end plate of one side of the right-angle fixing seat 41 can be first installed on the outer wall of the fixing frame composed of the two end frames 11 and the side frames 12, and then the two cylindrical shock absorbers 42 can be placed on the inner and outer sides of the end plate of the other side of the right-angle fixing seat 41, so that the through holes 421 on the two cylindrical shock absorbers 42 are aligned with the through holes 411 on the end plate of the other side of the right-angle fixing seat 41. Finally, one end of the extension bolt 43 is inserted into the two cylindrical shock absorbers 42 from the inner side of the right-angle fixing seat 41. The through hole 421 of the right-angle fixing seat 41 and the through hole 411 on the end plate on the other side of the right-angle fixing seat 41 are inserted into the through hole 421 and the through hole 411 on the end plate on the other side of the right-angle fixing seat 41, so that one end of the lengthening bolt 43 extends to the outside of the cylindrical shock absorber 42 located on the outside, and then the lengthening bolt 43 is screwed to fix it on the frame to complete the installation of the radiator frame. The cylindrical shock absorber 42 can buffer the force applied to the radiator frame, prevent the radiator frame from shaking due to the vibration of the frame, avoid the failure of the internal heat dissipation components of the radiator frame due to long-term vibration of the radiator frame, and protect the radiator.

[0045] The shock-absorbing assembly 4 also includes a rectangular silicone shock-absorbing pad 44 and a U-shaped silicone shock-absorbing pad 45, wherein the rectangular silicone shock-absorbing pad 44 is installed on the left and right sides of the heat dissipation core 21 and contacts the inner walls of the two side frames 12, and the U-shaped silicone shock-absorbing pad 45 is clamped and installed on the upper and lower ends of the end frame 11, and the outer wall of the U-shaped silicone shock-absorbing pad 45 is provided with a reinforcing rib 451, and the U-shaped silicone shock-absorbing pad 45 contacts the inner wall of the end frame 11 through the reinforcing rib 451.

[0046] In one embodiment, since the rectangular silicone shock-absorbing pad 44 and the U-shaped silicone shock-absorbing pad 45 are both installed on the outer wall of the heat dissipation core 21, when the heat dissipation core 21 is installed, the heat dissipation core 21 can be allowed to contact the inner walls of the end frame 11 and the side frame 12 through the rectangular silicone shock-absorbing pad 44 and the U-shaped silicone shock-absorbing pad 45 respectively. The rectangular silicone shock-absorbing pad 44 and the U-shaped silicone shock-absorbing pad 45 reduce the gap between the heat dissipation core 21 and the inner walls of the end frame 11 and the side frame 12, prevent the heat dissipation core 21 from having hard contact with the end frame 11 and the side frame 12, and avoid the heat dissipation core 21 being directly in contact with the radiator frame end, which causes the heat dissipation core 21 to be crushed when it is deformed by collision. The rectangular silicone shock-absorbing pad 44 and the U-shaped silicone shock-absorbing pad 45 play a role of buffering and protection, thereby protecting the heat dissipation core 21.

[0047] The working principle of the present invention is as follows: when the radiator is in use, the water in the two sets of rectangular water channels 22 can be circulated respectively through the two water inlets and outlets on the front side of the heat dissipation core 21, so that the two sets of rectangular water channels 22 and the wavy heat dissipation fins 23 on the outside thereof can respectively dissipate heat for the motor and the controller in the drive system, so that the heat dissipation water paths of the motor and the motor controller do not affect each other, thereby improving the reliability of the heat dissipation of the motor and the motor controller, and ensuring the heat dissipation effect of the motor and the motor controller. At the same time, the temperature of the coolant in the heat dissipation core 21 is detected by the temperature sensor 25, and the collected coolant temperature information is transmitted to the intelligent controller, which analyzes and processes the coolant temperature data collected by the temperature sensor 25, and controls the opening and closing and the number of revolutions of the fan body 32 according to the coolant temperature data, so that the number of opening and closing and the number of revolutions of the fan are matched with the actual heat exchange power of the radiator, thereby avoiding the excessive consumption of the battery of the drive system due to the simultaneous operation of each fan on the radiator, which not only reduces the operating cost and plays the role of energy saving and environmental protection, but also ensures the stability of the system and strong practicality.

[0048] Moreover, when maintaining the radiator, the radiator frame outside the heat dissipation core 21 can be directly disassembled to expose the heat dissipation core 21 inside the radiator frame, and the faulty parts on the heat dissipation core 21 can be repaired and replaced, avoiding the situation where the radiator frame needs to be cut to remove the heat dissipation core 21 due to welding. The fan can then be removed from the back of the fixed cover 31, avoiding the trouble of having to remove the fixed cover 31 to disassemble and maintain the fan, saving a lot of time and improving the maintenance efficiency of the radiator.

[0049] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
