Description

Technical Field

[0001] The utility model relates to the technical field of motor control boards, in particular to a brushless motor control board for an intelligent cooling fan. Background Art

[0002] The technology and performance of cooling fans have reached a mature stage, and new technologies are constantly emerging. Fan specifications range from 8mm to 280mm, voltages include 5V, 12V, 24V, 48V, 110V, 220V, 380V, and shapes include square, round, olive, etc.

[0003] The brushless DC motor used in large intelligent cooling fans consists of a motor body and a driver. It is a typical mechatronics product. Since the brushless DC motor operates in an automatic manner, it does not require an additional starting winding on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation, nor does it produce oscillation and loss of step when the load changes suddenly. The control board is an important component of the brushless motor. The existing control board has poor shock absorption performance during use, which can easily cause the internal electronic components to loosen, affecting the normal use of the control board.

[0004] An existing patent (publication number: CN 217545815 U) discloses a brushless motor control board, in which the user places the control board body on an elastic pad; then loosens two connecting columns, and under the joint action of a first spring and two second springs, two pressure plates press the control board body against two elastic pads, and the two elastic pads can support and buffer the control board body, while the support plate pushes the first rubber pad to further support the control board body, thereby improving the stability of the control board body installation; the control board body is installed inside a mounting plate, and the control board body can also be further protected.

[0005] However, the above technical solution still has certain defects. During the operation of the control board body, a large amount of heat will be generated because it controls the current output. When the electric fan runs for a long time, the control board body will overheat. When the control board body is overheated, if the room temperature is also high, it is very likely that the control board body will burn due to its own overheating, thereby causing the cooling fan to be unable to continue to be used. For this reason, a brushless motor control board for an intelligent cooling fan is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A brushless motor control board for an intelligent cooling fan, such as Figure 1-3 As shown, it includes a mounting plate 100, a top cover 101 is detachably connected to the top of the mounting plate 100, a control board body 103 is detachably connected to the top of the mounting plate 100, and a heat dissipation mechanism 200 is provided on the inner wall of the top cover 101;

[0028] The heat dissipation mechanism 200 includes a heat conducting plate 201, the inner wall of the top cover 101 is fixedly connected with the heat conducting plate 201, and the bottom end of the heat conducting plate 201 is tightly fitted with the top of the control board body 103, the top of the top cover 101 is fixedly connected with a U-shaped frame 202, the top of the heat conducting plate 201 is fixedly connected with multiple groups of heat conducting pipes 203, and the tops of the multiple groups of heat conducting pipes 203 are fixedly connected to the top of the inner wall of the U-shaped frame 202, the inner wall of the U-shaped frame 202 is fixedly connected with multiple groups of heat dissipation fins 204, and the inner walls of the multiple groups of heat dissipation fins 204 are fixedly connected to the outer walls of the multiple groups of heat conducting pipes 203 respectively, the right outer wall of the U-shaped frame 202 is fixedly connected with two groups of inlet fans 205, and the left outer wall of the U-shaped frame 202 is fixedly connected with two groups of outlet fans 206.

[0029] When the control board body 103 generates temperature, the temperature is transferred to the multiple groups of heat pipes 203 through the heat conducting plate 201, and the multiple groups of heat conducting pipes 203 can transfer the temperature to the multiple groups of heat dissipation fins 204, thereby increasing the contact area between the temperature and the air. The two groups of inlet fans 205 and the two groups of outlet fans 206 run simultaneously to drive the airflow to pass quickly through the multiple groups of heat dissipation fins 204, thereby taking away the temperature on the heat dissipation fins 204, thereby reciprocatingly dissipating the heat of the control board body 103.

[0030] Please refer to Figure 3 The inner wall of the heat pipe 203 is filled with coolant, the bottom of the heat conducting plate 201 is coated with thermal grease, and the heat conducting plate 201, the multiple groups of heat conducting pipes 203 and the multiple groups of heat dissipating fins 204 are all made of copper.

[0031] Thermal grease has good fluidity and thermal conductivity, and can fill the gap between the heat conducting plate 201 and the control board body 103, thereby improving the thermal conductivity of the heat conducting plate 201. The copper material has good thermal conductivity, which improves the thermal conductivity of the heat conducting plate 201, the heat conducting pipe 203 and the heat dissipation fins 204. It should be noted that the boiling point of the coolant is relatively low. When the temperature of the heat conducting plate 201 is transferred to the bottom of the heat conducting pipe 203, the temperature will be preferentially transferred to the coolant. The coolant is heated and vaporized and floats above the heat conducting pipe 203. The vaporized coolant with temperature will quickly transfer the temperature to the top of the heat conducting pipe 203, so that the heat conducting pipe 203 as a whole quickly absorbs heat, and the temperature can be evenly transferred to each group of heat dissipation fins 204, further improving the heat dissipation efficiency of the device.

[0032] Please refer to Figure 2-4 The bottom end of the mounting plate 100 is fixedly connected to the bottom plate 102, and the bottom end of the top cover 101 is provided with a quick mounting mechanism 300, which includes a plug 301, and the bottom end of the top cover 101 is fixedly connected to multiple groups of plugs 301, and the top of the mounting plate 100 is provided with multiple groups of slots 302, and the multiple groups of slots 302 are all inserted into the inside of the bottom plate 102, and the outer walls of the multiple groups of plugs 301 are respectively plugged into the inner walls of the multiple groups of slots 302, and the inner wall of the bottom plate 102 is slidably connected to two groups of connecting rods 303, and the outer wall of the two groups of connecting rods 303 close to each other is fixedly connected to two groups of Limit spring, the outer walls of the two groups of connecting rods 303 are respectively fixedly connected with two groups of clamping rods 304, and the ends of the multiple groups of clamping rods 304 are all arranged with inclined surfaces, the outer walls of the multiple groups of plugs 301 are all provided with clamping grooves 305, and the multiple groups of clamping grooves 305 are respectively matched with the ends of the multiple groups of clamping rods 304, the inner wall of the base plate 102 is rotatably connected with a gear 306, the outer walls of the two groups of connecting rods 303 on one side close to each other are fixedly connected with a rack 307, and the two groups of racks 307 are meshed with the gear 306, the outer wall of the gear 306 is fixedly connected with a knob, and the bottom end of the knob extends to the outside of the base plate 102.

[0033] When it is necessary to replace the silicone grease or repair the control panel body 103, it is only necessary to turn the knob to drive the gear 306 to rotate. When the gear 306 rotates, the two groups of connecting rods 303 are driven to approach each other through the two groups of racks 307. The two groups of connecting rods 303 can respectively drive the two groups of clamping rods 304 to separate from the two groups of clamping slots 305. At this time, the top cover 101 can be pulled out upward to replace the silicone grease or repair the control panel body 103. After the work is completed, it is only necessary to reinsert the plug 301 into the slot 302. The outer wall of the plug 301 can push the clamping rod 304 to one side through the inclined surface of the clamping rod 304. When the plug 301 is fully inserted into the interior of the slot 302, the clamping slot 305 just reaches the position of the clamping rod 304. At this time, the two groups of reset springs can push the two groups of connecting rods 303 to reset, thereby driving multiple groups of clamping rods 304 to enter multiple groups of clamping slots 305 at the same time, and the device is reinstalled.

[0034] Please refer to Figure 2-3 The outer wall of the control panel body 103 is provided with a plurality of positioning grooves 308, the top of the mounting plate 100 is provided with a plurality of fixing grooves 309, and the plurality of fixing grooves 309 correspond to the plurality of positioning grooves 308 respectively, the bottom end of the top cover 101 is fixedly connected with a plurality of positioning pins 310, and the outer walls of the plurality of positioning pins 310 respectively penetrate through the plurality of positioning grooves 308 and are inserted into the plurality of fixing grooves 309.

[0035] When the device is installed, the outer walls of the multiple groups of positioning pins 310 respectively penetrate the multiple groups of positioning grooves 308 and are inserted into the multiple groups of fixing grooves 309. The heat conducting plate 201 then presses the top of the control board body 103, thereby fixing the position of the control board body 103 and preventing the control board body 103 from moving.

[0036] When in use, the temperature generated by the control board body 103 can be transferred to the multiple groups of heat dissipation fins 204 through the heat conduction plate 201 and the heat conduction pipe 203, thereby increasing the contact area between the temperature and the air. At this time, the inlet fan 205 and the outlet fan 206 drive the air to pass quickly between the multiple groups of heat dissipation fins 204, thereby taking away the heat on the heat dissipation fins 204, thereby dissipating the heat of the control board body 103, which can prevent the control board from burning due to its own high temperature and increase the service life of the heat dissipation fan. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
