Therefore, the embodiment of the utility model provides the heat dissipation device which is applied to heat dissipation of the functional components in the energy storage power supply and can achieve heat dissipation and water resistance.

Specifically, an embodiment of the present utility model provides a heat dissipating device applied to dissipating heat of a functional component in an energy storage power supply, where the heat dissipating device includes at least one heat dissipating wall configured to absorb heat dissipated by the functional component. The heat dissipation device is provided with a channel, the heat dissipation wall is isolated from the channel, the channel is configured to be used for cooling medium circulation, and the channel is configured to penetrate through two sides of the shell of the energy storage power supply.

In one embodiment, the cooling medium is air, but is not limited thereto. For example, in other embodiments, the cooling medium may be a cooled gas or a liquid.

The heat dissipation wall of the heat dissipation device contacts with the functional component and is isolated from the channel, so that the heat dissipation wall of the first aspect can contact with the functional component to conduct heat to the channel, and heat generated by the functional component is preferably dissipated. In the second aspect, the channel is isolated from the heat dissipation wall, so that the heat dissipation wall cannot be penetrated by the channel to increase the contact area between the heat dissipation wall and the functional component, and the heat conduction efficiency of the heat dissipation wall is improved. In the third aspect, the channel is isolated from the heat dissipation wall and penetrates through two sides of the shell of the energy storage power supply, so that even if water enters the channel from one side of the shell of the energy storage power supply, the water can be isolated from the functional component, and flows out from the other side of the shell, the waterproof performance of the functional component is improved, and the scene adaptation capability of the energy storage power supply with the heat dissipation device is also improved. Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1 and 2, an energy storage power supply 200 is provided according to an embodiment of the utility model. The energy storage power supply 200 is a structure for supplying electric power. For example, the energy storage power supply 200 may be applied to a home electric field scene or an outdoor electric scene.

The stored energy power supply 200 includes a plurality of functional components, a heat sink 100, and a housing 207. The functional components can generate heat when being electrified and operated, and the heat needs to be emitted to ensure the stable operation of the functional components and protect the functional components. The heat dissipation device 100 is used for dissipating heat from a functional component. The heat sink 100 conducts heat by contacting the functional components and dissipates the heat to the outside of the energy storage power source 200.

It will be appreciated that in other embodiments, the heat dissipation device 100 may be applied to other electronic devices (not shown), for example, the heat dissipation device 100 is used to dissipate heat from a plurality of circuit boards in the electronic device.

With continued reference to fig. 3, the heat dissipating device 100 includes at least one heat dissipating wall. The heat dissipation wall is configured to absorb heat dissipated by the functional component. In one embodiment, the heat dissipation wall is made of aluminum material, but is not limited thereto. For example, in another implementation, the heat dissipation wall may also be made of iron material. The heat sink 100 is provided with a channel 40, and the channel 40 penetrates through the outer walls 30 of two opposite sides of the heat sink 100. The channel 40 is isolated from the heat dissipation wall, i.e. the channel 40 does not penetrate to the outer surface of the heat dissipation wall, so as to increase the contact area between the heat dissipation wall and the functional component. The passage 40 penetrates both sides of the housing 207.

The heat dissipating device 100 is independent of the functional component in the energy storage power supply 200, and does not need to be arranged in the functional component, so that the space in the functional component is avoided being occupied, and the layout space of elements in the functional component is further improved.

The heat dissipation wall is in contact with the functional component, preferably dissipating heat generated by the functional component. The heat dissipation wall is isolated from the ventilation channel 40, absorbs heat of the functional component and conducts the heat to the channel 40, and the channel 40 is isolated from the heat dissipation wall, so that the heat dissipation wall cannot be penetrated by the channel 40 to increase the contact area between the heat dissipation wall and the functional component, and the heat conduction efficiency of the heat dissipation wall is improved.

Because the channel 40 is isolated from the heat dissipation wall and penetrates through two sides of the housing of the energy storage power supply 200, even if water enters the channel 40 from one side of the housing 207 of the energy storage power supply 200, the water can be isolated from the functional components, and flows out from the other side of the housing 207, thereby improving the waterproof capability and the scene adaptation capability of the energy storage power supply 200 with the heat dissipation device 100.

The plurality of functional components in the stored energy power supply 200 are a first functional component 201 and a second functional component 203, respectively. The first functional component 201 and the second functional component 203 are located on opposite sides of the heat sink 100, respectively. The at least one heat sink wall comprises a first heat sink wall 10 and a second heat sink wall 20. The first heat dissipation wall 10 and the second heat dissipation wall 20 are located at opposite sides of the heat dissipation device 100. The first heat dissipation wall 10 is in contact with and conducts heat from the first functional component 201, and the second heat dissipation wall 20 is in contact with and conducts heat from the second functional component 203.

The first heat dissipation wall 10 and the second heat dissipation wall 20 are located at two opposite sides of the heat dissipation device 100, which is beneficial to distributing functional components at the peripheral side of the heat dissipation device 100, and is beneficial to ensuring that the areas of the heat dissipation walls at the two opposite sides are equal or close, and reducing the area of the outer wall, except the heat dissipation walls, of the heat dissipation device 100 surrounding the channel 40, so that the overall volume of the heat dissipation device 100 is reduced. The two opposite sides of the heat dissipating device 100 can be in contact with the functional components to dissipate heat of the functional components at two sides of the heat dissipating device 100 to the outside, and the heat dissipation of the functional components can be realized by one heat dissipating device 100, which is beneficial to the compactness of the layout of the energy storage power supply 200.

With continued reference to fig. 5 and 6, in one embodiment, the first functional component 201 is a battery component, and the second functional component 203 is an inverter component, but is not limited thereto. For example, in other embodiments, the first functional component 201 may be another structure such as an electrical connector (e.g., a flexible circuit board for electrical connection between two structures).

The first functional component 201 includes a battery pack 2011 and a circuit board 2013 that are electrically connected. The circuit board 2013 is located between the heat sink 100 and the battery pack 2011. The circuit board 2013 is in contact with the first heat dissipation wall 10 and conducts heat. The circuit board 2013 electrically connected to the battery pack 2011 is centrally disposed on one side of the battery pack 2011, so that the first heat dissipation wall 10 is convenient to be in contact with the circuit board 2013 in the first functional module 201, and heat dissipation of the circuit board 2013 is guaranteed.

In one embodiment, the circuit board 2013 is a BATTERY management system (BATTERY MANAGEMENT SYSTEM).

In an embodiment, the projected areas of the first functional component 201 and the second functional component 203 projected toward the heat dissipating device 100 are close, so that the first functional component 201 and the second functional component 203 are disposed on opposite sides of the heat dissipating device 100, the internal layout of the energy storage power supply 200 is easy to be compact, and the contact area of the first heat dissipating wall 10 and the first functional component 201 and the contact area of the second heat dissipating wall 20 and the second functional component 203 are large enough to enable the heat generating parts in the first functional component 201 and the second functional component 203 to be in contact with the heat dissipating device 100.

It will be appreciated that in other embodiments, the first heat dissipation wall 10 and the second heat dissipation wall 20 may be disposed on two adjacent sides of the heat dissipation device 100, for example, as shown in fig. 4, the first functional component 201a and the second functional component 203a are disposed on two adjacent sides of the heat dissipation device 100 a. The battery pack 2011a and the circuit board 2013a are sequentially disposed, and the circuit board 2013a is located between the battery pack 2011a and the heat dissipating device 100 a.

The layout of the plurality of heat dissipation walls of the heat dissipation device 100 is set according to the positions of the plurality of functional components, and the heat dissipation device 100 is configured to be in contact with the circuit board 2013 and the second functional component 203.

It is understood that in other embodiments, the heat sink wall may contact a thermally conductive plurality of functional components. For example, when two of the three functional components are projected toward the heat sink 100 in a projection area close to a projection area of the remaining one functional component toward the heat sink 100, the first heat sink wall 10 is disposed in contact with the two heat sink components, and the second heat sink wall 20 is disposed in contact with the remaining one functional component.

The stored energy power supply 200 includes a housing 205, and a housing 207 is disposed on the housing 205. The rack 205 is used to support a plurality of functional components and the heat sink 100. The housing 207 is housed outside of the plurality of functional components, as shown in fig. 1 and 2. When the energy storage power supply 200 is installed in an electric device, the second functional component 203, the heat dissipation device 100 and the first functional component 201 are sequentially disposed along the up-down direction. The heat sink 100 is coupled to the frame 205 and to the second functional component 203. The second functional module 203 is located above the heat dissipating device 100, so that the heat dissipating device 100 dissipates heat to the second functional module 203 and supports the second functional module 203.

It will be appreciated that in other embodiments, the second functional component 203 may also be configured to connect with the chassis 205 and contact the heat sink 100, and that the heat sink 100 can also be configured to carry the second functional component 203.

The heat dissipating device 100 is connected to the frame 205 and carries the second functional component 203, which improves the stability of the second functional component 203 and prevents the force of the second functional component 203 pressed against the heat dissipating device 100 from being transferred to the battery component, thereby preventing the battery component from being pressed.

In one embodiment, the first functional component 201 is connected to the rack 205, but is not limited thereto. For example, in other embodiments, the first functional component 201 is connected to the heat dissipating device 100, and the heat dissipating device 100 provides a lifting force to the first functional component 201 to improve the stability of the first functional component 201. The first functional component 201 is connected to the lower portion of the heat dissipating device 100, and the heat dissipating device 100 applies a lifting supporting force to the first functional component 201, so that the heat dissipating device 100 is prevented from pressing the circuit board 2013 of the first functional component 201.

The first and second functional components 201 and 203 are configured to be located within the housing 207 to be isolated from the outside. The heat sink 100 is fixed to the housing 205, and the passage 40 is configured to be exposed from the housing 207 to communicate with the outside. The edges of the opening 401 of the channel 40 and the housing 207 are in sealing engagement.

The functional components are covered by the shell 207, so that the functional components are isolated from the outside, the opening 401 of the channel 40 is in sealing fit with the shell 207, and further, the outside liquid-solid impurities are prevented from entering the functional components through the edge of the opening 401, the waterproof performance of the energy storage power supply 200 is improved, and the scene adaptation capability of the energy storage power supply 200 is improved. For example, the energy storage power supply 200 can adapt to outdoor climate change, such as rain, and the rain does not contact the functional components, and the heat dissipating device 100 is exposed to the outside, so as to accelerate heat dissipation.

In one embodiment, the surface of the heat dissipation wall, which contacts the functional component, is approximately contoured to the heat-generating portion of the side of the functional component facing the heat dissipation wall. For example, the functional component is provided with a protruding structure protruding towards one side of the heat dissipation wall, and the heat dissipation wall correspondingly provides a concave structure which accommodates the contact protruding structure.

In one embodiment, the second functional component 203 is provided with a functional element 2031 protruding to one side, the heat dissipation wall is provided with a groove 21, and the functional element 2031 is accommodated in the groove 21. The functional element 2031 heats up during operation, causing the functional element 2031 to form a heat-generating location for the second functional assembly 203. The functional elements 2031 are encapsulated in the grooves 21, so that the protruding functional elements 2031 are in contact with the heat dissipation wall to conduct heat, and the heat-generating parts of the functional components can be in contact with the heat dissipation wall to conduct heat no matter the relative positions of the different functional elements 2031 in the second functional components 203, thereby improving the heat conduction effect of the heat dissipation wall of the heat dissipation device 100.

In one embodiment, the functional element 2031 is a capacitor, but is not limited thereto. For example, in other embodiments, the functional element 2031 may be a transformer structure, or a power supply board (power supply distribution, PSDR board).

It will be appreciated that, in other embodiments, when the side of the functional component facing the heat dissipation wall is a plane, the surface of the heat dissipation wall contacting the functional component may be a plane, so long as the heat dissipation wall contacts the functional component 2031 corresponding to different heat generating portions of the functional component 2031.

With continued reference to fig. 7, the direction in which the channel 40 penetrates the two opposite outer walls 30 of the heat sink 100 is set as a penetrating direction X, as shown in fig. 5. The heat sink 100 is provided with a plurality of partitions 41. The partition 41 extends in the penetrating direction X. The plurality of spacers 41 are disposed in the channel 40 at intervals, and divide the channel 40 into a plurality of sub-channels 402.

The plurality of sub-channels 402 enable the air flow entering the heat dissipation device 100 to be dispersed in each sub-channel 402, and the volume of the sub-channels 402 is far smaller than the volume of the channel 40 without the isolation portion 41, so that the air flow in the sub-channels 402 moves along the penetrating direction X, and further the air flow in the sub-channels 402 drives heat to be dissipated to the outside in time. However, the air flow of the passage 40 without the partition 41 has a problem of being dispersed in different directions, which results in a longer flow path of the air flow, and thus heat cannot be timely dissipated from the passage 40 to the outside.

In one embodiment, the isolation portion 41 is connected to the first heat dissipation wall 10 and the second heat dissipation wall 20 on opposite sides of the heat dissipation device 100, but is not limited thereto. For example, as shown in fig. 4, when the first functional module 201a and the second functional module 203a are located on two adjacent sides of the heat dissipating device 100a, the isolation portion (not shown) may also have an L shape, so that two ends of the isolation portion are respectively connected to the heat dissipating walls located on two adjacent sides of the heat dissipating device 100 a.

The isolation portion 41 is connected to the heat dissipation walls on opposite sides, so as to facilitate uniform distribution of the sub-channels 402, and improve uniformity of heat dissipation to the outside.

Referring to fig. 5, in an embodiment, the heat dissipation wall is provided with a plurality of heat conduction portions 23, and the heat conduction portions 23 are configured to correspond to heat-generating portions in the functional component. For example, the second heat dissipation wall 20 is provided with a plurality of heat conduction portions 23, the heat conduction portions 23 are of a copper sheet structure, and the heat conduction coefficient of the heat conduction portions 23 is higher than that of the second heat dissipation wall 20, so that the heat conduction portions 23 can rapidly conduct the heat of the heat generating portion of the second functional module 203 to the second heat dissipation wall 20, thereby avoiding heat from being accumulated at the heat generating portion of the second functional module 203 and improving the heat dissipation effect.

It will be appreciated that in other embodiments, the heat conducting portion 23 may be a copper tube structure, and the copper tube may be filled with a cooling medium.

Referring to fig. 2, the energy storage power supply 200 further includes a fan 209. The fan 209 is disposed at an opening of the channel 40 exposed at one side of the energy storage power source, and configured to blow air to the channel 40. The wind blown by the fan 209 enters from the opening 401 of the duct 40 and drives heat in the penetrating direction X to be conducted to the outside of the duct 40.

The fan 209 can accelerate the airflow velocity in the channel 40, thereby improving the heat dissipation efficiency.

It can be appreciated that in other embodiments, the fans 209 may be disposed on opposite sides of the channel 40 along the through direction X, wherein the fans 209 on one side of the channel 40 blow air to the channel 40, and the fans 209 on the other side of the channel 40 suck air to the channel 40, so as to further increase the flow speed of the air flow in the channel 40, thereby further improving the heat dissipation effect.

The heat dissipating device 100 is independent of the functional component in the energy storage power supply 200, and does not need to be arranged in the functional component, so that the space in the functional component is avoided being occupied, and the layout space of elements in the functional component is further improved.

Further, the heat dissipation wall is in contact with the functional component, preferably dissipating heat generated by the functional component.

Further, the heat dissipation wall is isolated from the ventilation channel 40, the heat dissipation wall absorbs the heat of the functional component and conducts the heat to the channel 40, and the channel 40 is isolated from the heat dissipation wall, so that the heat dissipation wall cannot be penetrated by the channel 40 to increase the contact area between the heat dissipation wall and the functional component, and the heat conduction efficiency of the heat dissipation wall is improved.

Further, the channel 40 is isolated from the heat dissipation wall and penetrates through two sides of the housing of the energy storage power supply 200, so that even if water enters the channel 40 from one side of the housing 207 of the energy storage power supply 200, the water can be isolated from the functional components, and flows out from the other side of the housing 207, thereby improving the waterproof capability and the scene adaptation capability of the energy storage power supply 200 with the heat dissipation device 100.

The above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and substance of the technical solution of the present utility model.
