A heat dissipation assembly and motor controller

Abstract

This invention provides a heat dissipation component and a motor controller, including a set of heat dissipation substrates and heat dissipation fins disposed on the heat dissipation substrates. It also includes an emergency heat dissipation component disposed outside the heat dissipation substrates. The emergency heat dissipation component includes a water tank disposed on one side of each heat dissipation substrate, a set of infrared temperature sensors installed on the side of each water tank near the heat dissipation substrate, and a heat dissipation structure disposed on each water tank. Through the emergency heat dissipation component, the surface temperature of the heat dissipation substrates can be monitored in real time. Once a sharp increase in temperature is detected, a micro-pump will draw coolant to flow inside the heat dissipation substrate, absorbing heat from the substrate. This can quickly control the internal temperature of the motor controller within a safe range in the event of a short-term motor overload causing a sharp increase in the internal temperature of the motor controller, further slowing down the aging of the internal components of the motor controller.

Description

Technical Field

[0001] This utility model relates to the field of motor controller technology, and in particular to a heat dissipation component and a motor controller. Background Technology

[0002] As the core control component of a motor, the motor controller generates a lot of heat when operating under high load for extended periods. To ensure that the motor controller remains within a suitable temperature range during long-term operation, it is necessary to dissipate heat to maintain the stable performance of the internal electronic components and extend the service life of the motor controller.

[0003] Currently, the method for heat dissipating heat from the outside of a motor controller is to install heat sink fins on its casing. However, the heat sink fins have a slow heat dissipation rate. When the motor is briefly overloaded, it will generate instantaneous high temperature, and the internal temperature of the motor controller will rise sharply. The heat sink fins alone are not effective in heat dissipation, and the instantaneous high temperature will accelerate the aging of internal components. Therefore, we provide a heat dissipation component and a motor controller. Utility Model Content

[0004] This invention provides a heat dissipation component and a motor controller, which can accurately detect in real time the situation where the internal temperature of the motor controller rises due to short-term motor overload, and can also quickly cool down instantaneous high temperature, thereby significantly improving heat dissipation efficiency.

[0005] The purpose and effect of this utility model of a heat dissipation component and motor controller are achieved by the following specific technical means: A heat dissipation component includes a set of heat dissipation substrates and heat dissipation fins disposed on the heat dissipation substrates, and further includes:

[0006] An emergency heat dissipation component is disposed on the outside of a heat dissipation base plate, including a water tank disposed on one side of each heat dissipation base plate, a set of infrared temperature sensors installed on the side of each water tank near the heat dissipation base plate, and a heat dissipation structure disposed on each water tank.

[0007] A connecting component, located outside the heat dissipation base plate, is used to stabilize the water storage tank on one side of the heat dissipation base plate.

[0008] Preferably, the heat dissipation structure of the emergency heat dissipation component includes a miniature pump body installed on the front of each water tank. The input end of each miniature pump body is connected to the front of the water tank via a suction pipe. The output end of each miniature pump body is connected to a multi-port pipe. The multiple output ends of each multi-port pipe are threadedly connected to heat absorption pipes via threaded joints. The other end of each heat absorption pipe passes through the heat dissipation substrate and extends to the other side of the heat dissipation substrate.

[0009] Preferably, the output end of each group of heat-absorbing tubes is connected to a return water pipe through a threaded joint, and the output end of each return water pipe is connected to the back of the water storage tank.

[0010] Preferably, each of the water storage tanks has a partition fixedly connected to its inner wall, a set of heat dissipation blocks are embedded on the side of each water storage tank away from the heat dissipation base plate, a connecting pipe is embedded on each partition, and a solenoid valve is provided on each connecting pipe.

[0011] Preferably, each of the water storage tanks has a viewing window on the side away from the heat dissipation substrate, and each of the water storage tanks has a liquid injection pipe connected to the side away from the heat dissipation substrate, and each of the liquid injection pipes has a sealing plug at the input end.

[0012] Preferably, the connecting assembly includes two sets of inserts installed on the outside of each heat dissipation substrate. Each insert has a post inserted inside, and an L-shaped plate is slidably connected to the outside of each set of posts. The ends of each set of L-shaped plates that are close to each other are connected to the outer surface of the water storage tank.

[0013] Preferably, a retaining ring is fixedly connected to the outer surface of each of the inserts, and a spring is sleeved on the outer surface of each of the inserts.

[0016] A motor controller includes a heat dissipation component and a motor controller body.

[0017] Beneficial effects:

[0018] 1. The emergency heat dissipation components can monitor the surface temperature of the heat dissipation substrate in real time. Once a sharp increase in temperature is detected, the micro pump will draw coolant to flow inside the heat dissipation substrate and absorb the heat on the substrate. In the event of a short-term overload of the motor and a sharp increase in the internal temperature of the motor controller, the internal temperature of the motor controller can be quickly controlled within a safe range, further slowing down the aging of the internal components of the motor controller.

[0019] 2. Through the combination of heat dissipation blocks, baffles, and connecting pipes, the baffles can separate the internal space of the water storage tank, preventing the coolant that absorbs heat from mixing with unused coolant, thus further ensuring the cooling effect. At the same time, the heat dissipation blocks can cool down the coolant that absorbs heat. Then, by opening the solenoid valve on the connecting pipe, the coolant will flow to the other side of the water storage tank for recycling. The connecting components can stabilize the water storage tank, thereby ensuring the normal flow of coolant. At the same time, the water storage tank and its associated equipment can be disassembled for easy maintenance by staff. Attached Figure Description

The micro pump 303 will draw coolant from the water tank 301. The coolant will enter the heat absorption pipe 306 through the multi-port pipe 305. When the coolant flows inside the heat absorption pipe 306, it will absorb heat from the heat dissipation substrate 1, thereby achieving a rapid cooling effect, further reducing the internal temperature of the motor controller body 5, and slowing down the aging of the internal components of the motor controller body 5.
