Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
A motor apparatus 1 according to an embodiment of the present disclosure is described below with reference to fig. 1 to 4.
As shown in fig. 1 and 2, the motor apparatus 1 according to the embodiment of the present disclosure includes a motor body 10, a cooling part 20, a heat radiating part 30, and a control device (not shown in the drawings).
Specifically, at least a portion of the outer surface of the motor body 10 forms a heat dissipation region 11, and the motor body 10 is provided with a temperature sensor (not shown in the drawings) for detecting the operating temperature thereof. The refrigerating part 20 comprises at least one semiconductor refrigerating member 21, and the semiconductor refrigerating member 21 is arranged in the heat dissipation area 11. The heat dissipating unit 30 includes a heat absorbing member 31, a heat dissipating member 32 and a pump 33, the heat absorbing member 31 is disposed in the heat dissipating region 11, a first refrigerant channel 31a is disposed inside the heat absorbing member 31, a second refrigerant channel 32a (as shown in fig. 4) is disposed inside the heat dissipating member 32, the first refrigerant channel 31a and the second refrigerant channel 32a are communicated with each other through a refrigerant pipeline 40, and the pump 33 is disposed in the refrigerant pipeline 40. The control device is used for controlling at least one of the pump body 33 and the semiconductor refrigerating member 21 to work according to the detection result of the temperature sensor.
For example, the heat dissipation region 11 may be formed in any region of the outer surface of the motor body 10. For example, the outer surface of the motor body 10 has two relatively smooth side surfaces oppositely disposed, and the heat dissipation areas 11 are two and are respectively formed by the two relatively smooth side surfaces.
The temperature sensor may take various forms known to those skilled in the art now and in the future, and will not be described in detail herein, so long as it is capable of measuring the operating temperature of the motor body 10. In addition, the setting position of the temperature sensor on the motor body 10 is not specifically limited in the embodiment of the present disclosure, and the temperature sensor may be set at any position on the motor body 10 according to actual needs, for example, a position on the motor body 10 where heat generation is significant may be provided.
The semiconductor cooling member 21 is a cooling device composed of a semiconductor, for example. The semiconductor refrigerating member 21 includes a plurality of N-type semiconductors, a plurality of P-type semiconductors, and two insulating ceramic sheets. The N-type semiconductors and the P-type semiconductors are alternately connected in series between the two insulating ceramic plates, and any adjacent N-type semiconductor and P-type semiconductor are electrically conducted through the metal conductor. In the case of energization, the two insulating ceramic plates form the cold and hot ends of the semiconductor refrigerating element 21, respectively. Wherein, the cold junction of semiconductor refrigeration piece 21 sets up towards the heat dissipation region 11 and the laminating of motor body 10, and the hot junction of semiconductor refrigeration piece 21 deviates from the heat dissipation region 11 setting of motor body 10. Therefore, the cold end of the semiconductor refrigerating element 21 can absorb the heat emitted by the motor body 10, so as to cool the motor body 10.
The cooling medium used in the heat sink 32 may be a fluid that absorbs and releases heat through phase change, and may be water, for example. The heat absorbing member 31 is attached to the heat dissipation area 11, and a first refrigerant channel 31a inside the heat absorbing member 31 is used for flowing a refrigerant, and the refrigerant absorbs heat dissipated by the motor body 10 during flowing. The heat sink 32 and the heat absorbing member 31 are spaced apart from each other, a second refrigerant channel 32a inside the heat sink 32 is communicated with the first refrigerant channel 31a through a refrigerant pipeline 40, and the second refrigerant channel 32a inside the heat sink 32 is also used for flowing a refrigerant and releasing heat of the refrigerant during flowing. The pump body 33 is disposed in the refrigerant flow passage, and is configured to pump a high-temperature refrigerant after absorbing heat from the first refrigerant flow passage 31a to the second refrigerant flow passage 32a, and pump a low-temperature refrigerant after releasing heat to the first refrigerant flow passage 31a, so as to realize circulation of the refrigerant between the heat absorbing member 31 and the heat dissipating member 32, thereby realizing liquid cooling heat dissipation of the motor body 10.
In order to improve the heat absorption effect of the refrigerant flowing in the first refrigerant flow channel 31a, the first refrigerant flow channel 31a may be a multi-segment curved shape which is arranged in a winding manner to extend the flow path of the refrigerant in the first refrigerant flow channel 31a, thereby improving the heat absorption capacity of the refrigerant. Accordingly, in order to improve the heat dissipation effect of the refrigerant flowing through the second refrigerant flow channel 32a, the second refrigerant flow channel 32a may also adopt a multi-segment curved shape of meandering configuration to extend the flow path of the refrigerant in the second refrigerant flow channel 32a, thereby improving the heat dissipation of the refrigerant.
The control device is electrically connected with the temperature sensor, the pump body 33 and the semiconductor refrigerating element 21 respectively. Specifically, the control device is configured to receive a detection result of the temperature sensor, and output a control signal to the pump body 33 and the semiconductor cooling element 21, respectively, where the control signal is used to control at least one of the pump body 33 and the semiconductor cooling element 21 to operate.
In one example, the control device may be a Micro Control Unit (MCU), which is also called a Single Chip Microcomputer (Single Chip Microcomputer) or a Single Chip Microcomputer.
In addition, the control device may also adopt other forms of control devices, and the embodiment of the present disclosure is not limited in this respect.
It can be understood that, under the condition that the semiconductor refrigerating element 21 works, the semiconductor refrigerating element 21 is electrically conducted, so that the cold end of the semiconductor refrigerating element absorbs heat and the hot end of the semiconductor refrigerating element releases heat, thereby realizing the refrigeration effect on the motor body 10. When the pump body 33 is operated, the refrigerant circulates between the first refrigerant flow passage 31a and the second refrigerant flow passage 32a, thereby performing a liquid cooling heat dissipation function on the motor body 10.
Therefore, under the condition that the working temperature of the motor body 10 is low, the control device can control the pump body 33 or the semiconductor refrigerating element 21 to work so as to play a certain cooling role on the motor body 10. Under the condition that the working temperature of the motor body 10 is higher, the control device can control the pump body 33 and the semiconductor refrigerating piece 21 to work simultaneously so as to play a better cooling role for the motor body 10 and enable the working temperature of the motor body 10 to be reduced rapidly.
According to the electric machine 1 of the embodiment of the present disclosure, the cooling portion 20 and the cooling portion 30 are disposed in the cooling region 11 of the electric machine body 10, so that thermoelectric cooling and/or liquid cooling of the electric machine body 10 can be realized, the cooling effect of the electric machine body 10 is improved, and the working stability of the electric machine 1 is further improved. And, through setting up the controlling means who is connected with temperature sensor, pump body 33 and semiconductor heat sink 32 electricity respectively, controlling means controls pump body 33 and/or semiconductor refrigeration piece 21 work according to temperature sensor's testing result to can realize solitary thermoelectric refrigeration or liquid cooling refrigeration to motor body 10, perhaps carry out thermoelectric refrigeration and liquid cooling refrigeration simultaneously, from this, to the operating temperature that motor body 10 is different, multiple refrigeration mode has been realized, thereby when improving the refrigeration effect to motor body 10, the electric power cost among the refrigeration process has been reduced.
In one embodiment, the control device is configured to:
under the condition that the detection result of the temperature sensor accords with a first preset condition, controlling the pump body 33 to work and controlling the semiconductor refrigerating piece 21 to stop working; alternatively, the pump body 33 is controlled to stop operating and the semiconductor cooling member 21 is controlled to operate.
For example, the first preset condition may be that the detection result of the temperature sensor is in a preset temperature range. Under the condition that the working temperature of the motor body 10 is within the preset temperature range, the control device controls the pump body 33 to be opened and controls the semiconductor refrigerating element 21 to be closed so as to realize liquid cooling refrigeration of the motor body 10; alternatively, the control device controls the pump body 33 to be closed and controls the semiconductor refrigerating element 21 to be opened, so as to realize thermoelectric refrigeration on the motor body 10.
The preset temperature range may be specifically set according to an actual situation, and this is not specifically limited in the embodiments of the present disclosure.
In one specific example, the preset temperature range may include a first preset temperature range and a second preset temperature range, and a minimum temperature value of the second preset temperature range is greater than or equal to a maximum temperature value of the first preset temperature range. Under the condition that the working temperature of the motor body 10 is in the first preset temperature range, the control device controls the pump body 33 to work and controls the semiconductor refrigerating element 21 to stop working so as to realize liquid cooling refrigeration of the motor body 10. Under the condition that the working temperature of the motor body 10 is in the second preset temperature range, the control device controls the pump body 33 to stop working and controls the semiconductor refrigerating piece 21 to work so as to realize thermoelectric refrigeration on the motor body 10.
Through the above embodiment, under the condition that the working temperature of the motor body 10 is detected to meet the first preset condition, the liquid cooling refrigeration or the thermoelectric refrigeration of the motor body 10 can be realized by controlling one of the pump body 33 and the semiconductor refrigeration piece 21 to work.
In one embodiment, the control apparatus is further configured to:
and under the condition that the detection result of the temperature sensor meets a second preset condition, controlling the pump body 33 and the semiconductor refrigerating part 21 to work simultaneously.
For example, the second preset condition may be that the detection result of the temperature sensor is in a preset temperature range. More specifically, the preset temperature range may be a third preset temperature range, and a minimum temperature value of the third preset temperature range is greater than or equal to a maximum value of the second preset temperature range. Under the condition that the working temperature of the motor body 10 is within the third preset temperature range, the control device controls the pump body 33 and the semiconductor refrigerating piece 21 to work simultaneously, so that thermoelectric refrigeration and liquid cooling refrigeration are simultaneously carried out on the motor body 10.
Through the above embodiment, under the condition that the operating temperature of the motor body 10 is high and meets the second preset condition, the refrigerating part 20 and the heat radiating part 30 can be simultaneously utilized to perform thermoelectric refrigeration and liquid cooling refrigeration on the motor body 10, so that the refrigerating effect on the motor body 10 is maximally improved, the motor body 10 is rapidly cooled, and the operational reliability of the motor device 1 is further ensured.

Illustratively, the fixing groove 111 is formed by inwardly recessing an outer surface of the motor body 10 forming the heat dissipation region 11. The shape of the fixing groove 111 may be adapted to the shape of the semiconductor cooling member 21 so that the semiconductor cooling member 21 is embedded in the fixing groove 111. The cold end of the semiconductor refrigerating element 21 is attached to the inner wall of the fixing groove 111, and the hot end of the semiconductor refrigerating element is away from the outer surface of the motor body 10.
The heat absorbing member 31 may be provided in a plate shape, and the shape of the heat absorbing member 31 is adapted to the shape of the heat dissipation area 11. The heat absorbing member 31 may be fixed to the heat dissipation area 11 by a fastening member such as a screw, so that a side surface of the heat absorbing member 31 is attached to the heat dissipation area 11.
Through the embodiment, the fixing effect of the semiconductor refrigerating piece 21 on the heat dissipation area 11 is improved, and the heat exchange efficiency of the semiconductor refrigerating piece 21 and the heat dissipation area 11 is improved; in addition, by attaching the heat sink 32 to the heat dissipation region 11, the heat sink 32 and the motor body 10 can be made more compact, and the overall size of the motor apparatus 1 can be reduced.

Through the above embodiment, the arrangement of the leads 22 of the plurality of semiconductor cooling members 21 is reasonable, and the influence of the leads 22 on the installation of the heat absorbing member 31 on the heat dissipation area 11 is avoided.
In one embodiment, the heat dissipation area 11 is a plurality of areas, and the cooling portion 20 and the heat absorbing member 31 are a plurality of areas corresponding to the plurality of heat dissipation areas 11.
In one example, the heat dissipation regions 11 may be two and formed by two side surfaces opposite to each other on the motor body 10, respectively. The cooling portion 20 and the heat absorbing member 31 are respectively two provided corresponding to the two heat dissipation areas 11.
