In the power supply device provided by the application, the heat dissipation assembly is applied, so that the power supply device has a good heat dissipation effect and is convenient to assemble and disassemble.
The heat dissipation assembly and the power supply device provided by the application are described in detail below with reference to specific embodiments.
An embodiment of the present application provides a heat dissipating assembly, which is shown in fig. 1, and includes a heat dissipating base 100, a heat conducting member 200, and a driver 300. The heat dissipation assembly can be applied to a power supply device.
The heat dissipation base 100 is a base member of the heat dissipation assembly of the present application, and the heat dissipation base 100 may provide a mounting base for at least some other components of the heat dissipation assembly. The heat conducting member 200 is disposed on the heat dissipating base 100, and the heat conducting member 200 is disposed in contact with the heat dissipating base 100, so that heat of the heat conducting member 200 can be conducted to the heat dissipating base 100. The heat conducting member 200 is movably disposed on the heat dissipating base 100, so that the relative positions of the heat conducting member 200 and the heat dissipating base 100 can be changed, specifically, the driver 300 is connected to the heat conducting member 200, and the driver 300 can drive the heat conducting member 200 to move along the direction facing the heat dissipating base 100 or the direction facing away from the heat dissipating base 100. When the driver 300 drives the heat conductive member 200 to move in a direction away from the heat dissipation base 100, the heat conductive member 200 may be moved into contact with the battery member 400. It should be understood that heat is generated from the battery member 400 during the operation, so that the temperature of the battery member 400 is increased, and after the heat conductive member 200 contacts the battery member 400, the heat generated from the operation of the battery member 400 may be transferred to the heat conductive member 200 and then to the heat dissipation base 100, so that the temperature of the battery member 400 may be reduced.
Both the heat dissipation base 100 and the heat conduction member 200 may be made of a material having good heat conduction properties, so that heat of the battery compartment may be more efficiently conducted to the heat conduction member 200 and the heat dissipation base 100. The surface area of the heat dissipation base 100 may be relatively large, and the heat dissipation base 100 may be made of a material with good heat conduction performance, so that after heat is conducted to the heat dissipation base 100, the heat may be more efficiently dispersed to each part of the heat dissipation base 100, and thus the heat may be more efficiently dissipated through the heat dissipation base 100. Thus, the higher the heat dissipation efficiency of the heat dissipation base 100 is, the higher the efficiency of heat conduction from the battery member 400 to the heat dissipation base 100 through the heat conduction member 200 is.
Specifically, when the temperature of the battery member 400 is higher and exceeds the safe operating temperature, the driver 300 drives the heat conducting member 200 to move towards the battery member 400 to contact with the battery member 400, so as to dissipate heat of the battery member 400. When the temperature of the battery member 400 is low and is below the safety temperature, the driver 300 drives the heat conducting member 200 to move away from the battery member 400. Thus, the heat conductive member 200 does not contact the battery member 400, and the heat conductive member 200 and the battery member 400 can be prevented from interfering with each other. When the heat dissipation assembly of the present application needs to be disassembled, the heat conduction member 200 can be driven to be separated from the battery member 400 by the driver 300, so that the battery member 400 can be conveniently disassembled.
In some embodiments, referring to fig. 1 and 2, the battery member 400 of the present application may include a battery body 410 and a connection part 420, wherein the connection part 420 is electrically connected with the battery body 410. The connection part 420 is an electrical connection part 420 of the battery pack 400, and the battery body 410 may be electrically connected with other components through the connection part 420. Further, since the connection part 420 needs to be energized, the temperature of the connection part 420 is relatively high. When the driver 300 drives the heat conducting member 200 to move away from the heat dissipation base 100, the heat conducting member 200 can be driven to move to contact with the connecting portion 420, so that the heat of the connecting portion 420 can be conducted to the heat conducting member 200 and further to the heat dissipation base 100. Since the connection part 420 is in a conductive structure, and the heat conductive member 200 may be made of a metal material for good heat conductive performance, the heat conductive member 200 may be in insulating contact with the connection part 420 for preventing a short circuit caused by the contact of the heat conductive member 200 with the connection part 420.
In some embodiments, referring to fig. 1 and 2, the battery member 400 may further include an insulating sleeve 430, wherein the insulating sleeve 430 is sleeved on at least a portion of the connection portion 420, such that at least a portion of the connection portion 420 may be covered by the insulating sleeve 430. The insulating sleeve 430 is positioned between the heat conductive member 200 and the connection part 420, and the heat conductive member 200 may be indirectly contacted with the connection part 420 by contacting the insulating sleeve 430. The insulating sleeve 430 may make the heat conductive member 200 in insulating contact with the connection part 420, preventing the heat conductive member 200 and the connection part 420 from being electrically conductive to each other. The insulating sleeve 430 is sleeved on the connection part 420 to protect the connection part 420, so that the heat conducting member 200 and the connection part 420 can be worn away when the heat conducting member 200 moves towards and contacts the connection part 420.
Specifically, the cavity of the insulating sleeve 430 for accommodating the connecting portion 420 may be configured to match the external shape of the connecting portion 420, so that the insulating sleeve 430 and the connecting portion 420 may be connected in an interference fit manner, and thus the connecting effect between the insulating sleeve 430 and the connecting portion 420 is more stable and reliable, so as to prevent the insulating sleeve 430 and the connecting portion 420 from being separated from each other.
In addition, in other embodiments, an insulating sleeve 430 may be disposed around the heat conducting member 200, and the insulating sleeve 430 is located between the heat conducting member 200 and the connecting portion 420, so that the insulating sleeve 430 may also separate the heat conducting member 200 from the connecting portion 420, so that the heat conducting member 200 is in insulating contact with the connecting portion 420. The insulating sleeve 430 may be integrally formed with the connection portion 420 or the heat conductive member 200, so that the connection effect between the insulating sleeve 430 and the connection portion 420 or the heat conductive member 200 is more stable and reliable when the insulating sleeve 430 and the connection portion 420 are integrally formed.
In some embodiments, referring to fig. 1 and 3, the heat conductive member 200 of the present application may include a substrate 210, a heat conductive part 220, and a support bar 230. The substrate 210 is a basic component of the heat conductive member 200, the substrate 210 may provide a mounting base for other at least part of the components of the heat conductive member 200, and the substrate 210 is disposed on the heat dissipation base 100, so that the substrate 210 may be fixed. One end of the supporting rod 230 may be disposed on the substrate 210, the other end of the supporting rod 230 may be connected to the heat conducting portion 220, and the supporting rod 230 is movably supported on the heat conducting portion 220, so that the distance between the heat conducting portion 220 and the substrate 210 may be adjusted. The driver 300 may be disposed on the substrate 210, and the driver 300 is configured to drive the heat conducting portion 220 to move, so that the heat conducting portion 220 may contact with the connecting portion 420, and thus the heat of the connecting portion 420 may be conducted to the heat conducting portion 220, further conducted to the substrate 210 through the support rod 230, and finally conducted to the heat dissipation base 100 through the substrate 210.
The supporting rod 230 is movably supported on the heat conducting portion 220, so that when the distance between the heat conducting portion 220 and the substrate 210 is changed, both ends of the supporting rod 230 can be always connected with the heat conducting portion 220 and the substrate 210, and heat can be always conducted between the heat conducting portion 220 and the substrate 210 through the supporting rod 230. The number of the support rods 230 may be further set to be plural, the plurality of support rods 230 may be disposed on the substrate 210 along a predetermined direction, and the other end of the support rod 230 may be connected to a plurality of portions of the heat conducting portion 220, so that the support rod 230 is supported on the heat conducting portion 220 to make the structure of the heat conducting portion 220 more stable, and meanwhile, the efficiency of heat conduction from the heat conducting portion 220 to the substrate 210 may be increased.
The actuator 300 may specifically adopt a telescopic motor structure or a telescopic cylinder structure, and an output end of the actuator 300 may be disposed towards the heat conducting portion 220, and movement of the output end of the actuator 300 may drive the heat conducting portion 220 to move correspondingly, so that the heat conducting portion 220 may move towards the connecting portion 420 to contact with the moving portion.
In some embodiments, referring to fig. 1, 3 and 4, the support bar 230 of the present application may include a first bar portion 231 and a second bar portion 232. The first rod portion 231 may be fixed to the substrate 210, the second rod portion 232 may be movably sleeved in the first rod portion 231, and an end of the second rod portion 232 opposite to the first rod portion 231 is connected to the heat conducting portion 220. Thus, the second rod 232 can move relative to the first rod 231, and when the driver 300 drives the heat conducting part 220 to move, the second rod 232 can be always connected with the heat conducting part 220, and the second rod 232 moves relative to the first rod 231. The heat of the heat conductive part 220 may be sequentially transferred to the substrate 210 through the second rod part 232 and the first rod part 231.
Specifically, the inner diameter of the first rod portion 231 may be configured to match the outer diameter of the second rod portion 232, such that the outer wall of the second rod portion 232 is always in contact with the inner wall of the first rod portion 231 during the movement of the second rod portion 232 relative to the first rod portion 231, and thus the heat of the second rod portion 232 may be sufficiently conducted to the first rod portion 231.
In addition, in other embodiments, the support rod 230 may also be configured to be deformable, such as an elastic member. When the heat conducting part 220 moves away from the substrate 210, the support bar 230 may be stretched and deformed, and at this time, both ends of the support bar 230 may remain connected to the substrate 210 and the heat conducting part 220, so that heat of the heat conducting part 220 may be conducted to the substrate 210.
In some embodiments, referring to fig. 1 and 5, the heat dissipation base 100 may further be provided with a fixing groove 111 matching with the shape of the substrate 210, so that at least a portion of the substrate 210 may be embedded in the fixing groove 111, and thus the connection effect between the substrate 210 and the heat dissipation base 100 is more stable and reliable. After the substrate 210 is embedded in the fixing groove 111, the bottom wall and the side wall of the substrate 210 can be in contact with the inner wall of the fixing groove 111, so that the contact area between the substrate 210 and the fixing groove 111 is larger, and the efficiency of heat conduction from the substrate 210 to the heat dissipation base 100 is higher, so that the heat of the connecting portion 420 can be dissipated more efficiently. The substrate 210 may be disposed to be completely embedded in the fixing groove 111, so that the contact area between the substrate 210 and the heat dissipation base 100 may be further increased.
Specifically, the heat dissipation base may include a heat dissipation base plate 110 and a heat dissipation shroud 120, the heat dissipation shroud 120 may be disposed on the heat dissipation base plate 110, and the fixing groove 111 may be formed on the heat dissipation base plate 110. The fixing groove 111 may further be provided with a heat dissipation adhesive layer 130, and the substrate 210 may be fixed in the fixing groove 111 through the heat dissipation adhesive layer 130. The heat dissipation adhesive layer 130 not only can make the connection between the substrate 210 and the heat dissipation base plate 110 more stable and reliable, but also can make the heat transfer efficiency between the substrate 210 and the heat dissipation base plate 110 higher.
In some embodiments, referring to fig. 3, the heat conducting portion 220 may further be provided with a positioning groove 221, where the positioning groove 221 is located on a side of the heat conducting portion 220 facing the connection portion 420, and when the heat conducting portion 220 contacts with the connection portion 420, at least a portion of the connection portion 420 may be embedded in the positioning groove 221 of the heat conducting portion 220. By embedding the connection portion 420 into the positioning groove 221 of the heat conducting portion 220, the contact effect between the connection portion 420 and the heat conducting portion 220 is more stable and reliable, so that the heat conduction efficiency from the connection portion 420 to the heat conducting portion 220 is better. The size of the groove of the positioning groove 221 may be set to match the shape of the side of the connection part 420 facing the heat conducting part 220, so that when the connection part 420 is embedded in the positioning groove 221, the outer wall of the connection part 420 may be fully contacted with the inner wall of the positioning groove 221, so that the contact area between the connection part 420 and the heat conducting part 220 may be further increased, and the heat conducting efficiency between the connection part 420 and the heat conducting part 220 may be further increased.
Specifically, at least a portion of the insulating sleeve 430 is also positioned in the positioning groove 221 of the heat conducting portion 220, such that an outer wall of the insulating sleeve 430 may contact an inner wall of the positioning groove 221 of the heat conducting portion 220, so that heat of the connection portion 420 may be conducted to the heat conducting portion 220 through the insulating sleeve 430.
In some embodiments, referring to fig. 3, a heat conducting layer 222 may be further disposed in the positioning groove 221 of the heat conducting portion 220, the heat conducting layer 222 may cover an inner wall of the positioning groove 221, and when the heat conducting portion 220 is embedded in the positioning groove 221, an outer wall of the insulating sleeve 430 may contact with the heat conducting layer 222. The heat conductive layer 222 may enable the heat of the connection part 420 to be more efficiently conducted to the heat conductive part 220 through the insulating cover 430. The heat conductive layer 222 may be made of heat conductive silicone grease, so that the heat conductive layer 222 is flexible, and thus the heat conductive layer 222 may be more fully contacted with the heat conductive part 220 and the insulating cover 430.
Specifically, the heat conductive layer 222 may be coated in the positioning groove 221 of the heat conductive portion 220 in advance, and when the driver 300 drives the heat conductive portion 220 to move toward the connection portion 420 such that the insulating sleeve 430 is embedded in the positioning groove 221 of the heat conductive portion 220, the insulating sleeve 430 may press the heat conductive layer 222, so that the heat conductive layer 222 may be deformed such that the heat conductive layer 222 may cover various portions of the insulating sleeve 430 and substantially fill in the gap between the insulating sleeve 430 and the inner wall of the positioning groove 221.
In some embodiments, referring to fig. 3, the output end of the driver 300 of the present application may be specifically a driving rod 310, one end of the driving rod 310 faces the heat conducting part 220, and the driving rod 310 may push the heat conducting part 220 to move. The driving rod 310 may be provided with a heat insulating pad such that the heat insulating pad is located between the driving rod 310 and the heat conducting part 220, and the heat insulating pad may insulate the heat conducting part 220 to some extent such that the amount of heat conducted from the heat conducting part 220 to the driver 300 is relatively small. This prevents excessive heat from being absorbed by the driver 300 to cause excessive temperature, thereby protecting the driver 300.
In some embodiments, referring to fig. 6, the heat dissipating assembly of the present application may further be configured to include a temperature monitoring module 500 and a control module 600. The temperature monitoring module 500 is configured to monitor the temperature of the battery piece 400, and specifically configured to monitor the temperature of the connection part 420. The control module 600 is electrically connected with the temperature monitoring module 500 and the driver 300, and the temperature of the connection part 420 monitored by the temperature monitoring module 500 may be transmitted to the control module 600. The temperature of the connection portion 420 monitored by the temperature monitoring module 500 can be compared with a preset temperature in the control module 600, if the temperature of the connection portion 420 is higher than the preset temperature, which indicates that the temperature of the connection portion 420 is too high, the control module 600 can control the driver 300 to drive the heat conducting portion 220 to move to contact with the connection portion 420. The heat of the connection portion 420 can be conducted to the heat conducting portion 220, and then finally conducted to the heat dissipation base 100 for dissipation.
If the temperature of the connection portion 420 is lower than the preset temperature, which indicates that the temperature of the connection portion 420 is normal, the control module 600 may control the driver 300 to drive the heat conducting portion 220 to move to be separated from the connection portion 420. Thus, the connection part 420 and the heat conduction part 220 are in a non-contact state, and the heat conduction part 220 and the connection part 420 can be prevented from interfering with each other.
The embodiment of the application also provides a power supply device, which comprises the battery piece 400 and the radiating component. Wherein, the battery member 400 may be disposed at a top side of the heat conductive part 220.
