Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation of motor controllers, and particularly relates to a heat dissipation structure of a motor controller. Background Art

[0002] A motor controller is a device that manages and controls the operation of an electric motor. It is commonly used in a variety of applications, including industrial machinery, automobiles, drones, home appliances, and more. The main functions of a motor controller include regulating the speed, torque, and direction of the motor, as well as protecting the motor from damage such as overload and overheating. These controllers can be implemented in a variety of ways, including traditional electrical control, digital control, and electronic control. Common types of motor controllers include DC motor controllers, AC motor controllers, stepper motor controllers, and more. Their design and functionality depend on the type of motor being controlled, the application requirements, and the performance specifications required. In order to prevent the motor controller from overheating and damage, a heat dissipation structure is generally added.

[0003] The motor controller mainly dissipates heat through the cooling fan installed inside. Long-term use of the fan blades and air ducts will easily accumulate dust, affecting the heat dissipation effect. The motor controller needs to be manually disassembled for cleaning, which is more troublesome. Utility Model Content

[0004] In order to solve the technical problem that the fan blades and air ducts inside the traditional motor controller are prone to accumulate dust after long-term use, affecting the heat dissipation effect, and the motor controller needs to be manually disassembled for cleaning, which is quite troublesome, the utility model provides the following technical solutions:

[0005] The utility model relates to a heat dissipation structure of a motor controller, comprising a motor controller body and a radiator, a mounting groove is provided at the rear end of the motor controller body and a first heat conductive block is embedded in the mounting groove, an air duct is provided in the radiator and a second heat conductive block is embedded in the bottom of the air duct, dust removal holes connected to the air duct are provided on both side end surfaces of the radiator, a heat dissipation vent connected to the air duct is provided on the top of the radiator, a plurality of heat dissipation fans are fixedly installed in the heat dissipation vent, and a dustproof net is fixedly installed on the top of the heat dissipation vent.

[0006] As a preferred technical solution of the present utility model, the first heat-conducting block and the second heat-conducting block are both made of high thermal conductivity brass material.

[0007] As a preferred technical solution of the utility model, the top of the first heat-conducting block and the bottom of the second heat-conducting block are correspondingly provided with mutually staggered heat-conducting fins.

[0008] As a preferred technical solution of the utility model, a plurality of ash guide grooves are provided on the top of the second heat conducting block.

[0009] As a preferred technical solution of the utility model, both side end surfaces of the motor controller body are provided with clamping holes, and both side end surfaces of the heat sink are provided with spring buckles corresponding to the clamping holes.

[0010] As a preferred technical solution of the utility model, two electrical contact grooves are provided at the rear end of the motor controller body, and two electrical springs are provided at the front end of the heat sink corresponding to the two electrical contact grooves.

[0011] As a preferred technical solution of the utility model, a blocking block is fixedly inserted in the dust removal hole.

[0012] The beneficial effects achieved by the utility model are:

[0013] Install the radiator from top to bottom in the installation slot on the back of the motor controller body. During the installation process, the electrical spring is compressed and automatically snapped into the electrical contact slot. The radiator is powered by the motor controller body. After installation, it is fixed by the snap-in action of the card hole and the spring buckle. The modular design is convenient for quick disassembly and installation.

[0014] The heat inside the motor controller is conducted through the first heat-conducting block, and then the heat on the first heat-conducting block is transferred to the second heat-conducting block by the effect of the staggered insertion of the second heat-conducting block. The heat dissipation fan rotates forward to take away the heat on the second heat-conducting block to achieve the purpose of active heat dissipation and improve the heat dissipation efficiency. The motor controller body is sealed as a whole and dust will not be introduced into the interior.

[0015] If the radiator needs to be dusted and cleaned, the controller can be removed, the cooling fan can be reversed or the cooling seal can be connected to an external blower, and the block can be removed. The airflow will guide the dust in the dust guide groove into the dust removal hole for discharge, thereby achieving the purpose of quick cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Figure 1-4 As shown, a heat dissipation structure of a motor controller includes a motor controller body 1 and a radiator 2, a mounting groove is provided at the rear end of the motor controller body 1 and a first heat conductive block 101 is embedded in the mounting groove, an air duct is provided in the radiator 2 and a second heat conductive block 201 is embedded in the bottom of the air duct, dust removal holes 204 connected to the air duct are provided on both side end surfaces of the radiator 2, a heat dissipation vent 206 connected to the air duct is provided on the top of the radiator 2, a plurality of heat dissipation fans 207 are fixedly installed in the heat dissipation vent 206, and a dustproof net 208 is fixedly installed on the top of the heat dissipation vent 206.

[0024] The first heat-conducting block 101 and the second heat-conducting block 201 are both made of high-thermal-conducting brass material. When in use, the use of high-thermal-conducting brass material can improve the thermal conductivity of the first heat-conducting block 101 and the second heat-conducting block 201 .

[0025] The top of the first heat-conducting block 101 and the bottom of the second heat-conducting block 201 are correspondingly provided with mutually staggered heat-conducting fins. When in use, the heat-conducting fins expand the contact area between the first heat-conducting block 101 and the second heat-conducting block 201.

[0026] A plurality of dust guiding grooves are provided on the top of the second heat conducting block 201. When in use, dust is stored through the dust guiding grooves. When cleaning, the dust can be guided into the dust removal hole 204 for discharge through the dust guiding grooves.

[0027] The motor controller body 1 has two side end faces with clamping holes 102 , and the heat sink 2 has two side end faces with spring clamps 203 corresponding to the clamping holes 102 . When in use, quick disassembly and assembly can be achieved through the clamping action of the clamping holes 102 and the spring clamps 203 .

[0028] Two electrical contact grooves 103 are provided at the rear end of the motor controller body 1, and two electrical spring clips 202 are provided at the front end of the radiator 2 corresponding to the two electrical contact grooves 103. When in use, after the radiator 2 is installed in the installation groove on the back of the motor controller body 1, the electrical spring clips 202 are compressed and automatically snapped into the electrical contact groove 103, and power is supplied to the radiator 2 through the motor controller body 1.

[0029] A blocking block 205 is fixedly inserted in the dust removal hole 204 . When in use, the dust removal hole 204 is blocked by the blocking block 205 when the radiator 2 is installed to prevent dust from entering. When cleaning dust, the blocking block 205 is removed and discharged through the dust removal hole 204 .

[0030] Specifically, when the utility model is used, the radiator 2 is installed from top to bottom in the installation groove on the back of the motor controller body 1. During the installation process, the electrical spring piece 202 is compressed and automatically snapped into the electrical contact groove 103, and the radiator 2 is powered by the motor controller body 1. After the installation is completed, the fixation is achieved by the snapping action of the snap hole 102 and the spring buckle 203. During daily use, the heat inside the motor controller is conducted through the first heat conducting block 101, and then the heat on the first heat conducting block 101 is transferred to the second heat conducting block 201 by the effect of the staggered plugging of the second heat conducting block 201 and the first heat conducting block 101. The heat dissipation fan 207 rotates forward to take away the heat on the second heat conducting block 201 to achieve the purpose of active heat dissipation. If it is necessary to remove dust from the radiator 2, the controller can be removed, and the heat dissipation fan 207 can be reversed or the heat dissipation seal can be connected to an external hair dryer, and the blocking block 205 can be removed. The wind flow will guide the dust in the dust guide groove into the dust removal hole 204 for discharge, thereby achieving the purpose of quick cleaning.
