[0019] In order to better understand the technical solution of the present invention, the following detailed description of the embodiments of the present invention is given with reference to the accompanying drawings.

[0020] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present invention, all other embodiments that a person skilled in the art can obtain without inventive efforts fall within the scope of protection of the present invention.

[0021] The terms used in the embodiments of the present invention are only for the purpose of describing particular embodiments, and are not intended to limit the present invention. The singular forms "a," "the," and "the" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms unless the context clearly dictates otherwise.

[0022] It should be understood that the term "and / or" used in this specification is only for describing the relation between related objects, and indicates that three kinds of relations can exist. For example, A and / or B can indicate three kinds of situations, namely, A exists alone, A and B exist simultaneously, and B exists alone. In addition, the symbol " / " in this specification generally indicates that the related objects before and after are in an "or" relationship.

[0023] It should be noted that directional terms such as "upper", "lower", "left", and "right" described in the embodiments of the present invention are described in terms of angles shown in the drawings and should not be understood as limitations on the embodiments of the present invention. In addition, it should be further noted that in the context, when referring to an element being connected to the "upper" or "lower" of another element, it may not only be directly connected to the "upper" or "lower" of the other element, but also indirectly connected to the "upper" or "lower" of the other element via an intermediate element.

[0024] As shown in FIG. 1, FIG. 2 and FIG. 3, an embodiment of the present application provides an energy storage converter, which includes a housing 1, a fan 2, a mounting member 3 and a heat generating member 4. A chamber 11 is provided in the housing 1, the fan 2 is located in the chamber 11 and attached to the inner wall of the chamber 11, the mounting member 3 is connected to the inner wall of the chamber 11 and located on the blowing side of the fan 2, and the first heat generating member 4 is attached to one side of the mounting member 3 along the thickness direction Z of the mounting member 3. The fan 2 is used to increase the air flow rate on both sides of the thickness direction Z of the mounting member 3. The mounting member 3 includes an air vent 31, which penetrates the mounting member 3 along the thickness direction Z, and a wind guide member 32 is provided on a side wall of the ventilation port 31 that is separated from the fan 2. Along the thickness direction Z of the mounting member 3, the air guide member 32 is bent in a direction separated from the first heat generating member 4 and extends to a side close to the fan 2.

[0025] During the operation of the energy storage converter, the first heat generating member 4 releases heat, and if the temperature of the first heat generating member 4 is too high, the energy storage converter cannot operate normally. By attaching the first heat generating member 4 to the blowing side of the fan 2, the air flow rate around the first heat generating member 4 can be improved, the heat dissipation effect for the first heat generating member 4 can be further improved, and the heat dissipation effect in the energy storage converter can be improved. Along the thickness direction Z of the mounting member 3, the mounting member 3 has a first side and a second side that are provided opposite to each other, and the first heat generating member 4 is attached to the first side of the mounting member 3. The mounting member 3 is provided on the blowing side of the fan 2 and divides the airflow blown out from the fan 2 into two parts, one of which is blown to the first side of the mounting member 3 where the first heat generating member 4 is provided, and the remaining part is blown to the second side of the mounting member 3 where the first heat generating member 4 is not provided. Based on the size of the energy storage converter and the limitations of the mounting position of the fan 2, the flow rate of the airflow blown onto the first side of the mounting member 3 is smaller than the flow rate of the airflow blown onto the second side of the mounting member 3, so that the mounting member 3 is provided with an air vent 31 so that both sides of the mounting member 3 in the thickness direction Z communicate with each other, and the air guide member 32 can conduct the airflow on the second side of the mounting member 3 to the first side, improving the flow rate of the airflow on the first side of the mounting member 3 and further improving the heat dissipation effect on the first heat-generating member 4.

[0026] As shown in FIG. 2, in one possible embodiment, the first heat-generating member 4 includes a circuit board 41 and a heat-generating element 42, the heat-generating element 42 is attached to the circuit board 41, and an air vent 31 is provided at a position of the mounting member 3 corresponding to the heat-generating element 42.

[0027] The circuit board 41 is attached to the mounting member 3 , and the heating element 42 is attached to the side of the circuit board 41 remote from the mounting member 3 .

[0028] The heating element 42 may be an electronic element such as a relay, and during the operation of the energy storage converter, the heating element 42 releases heat, which leads to an increase in temperature at the position of the circuit board 41 where the heating element 42 is provided. The ventilation hole 31 is located at a position corresponding to the heating element 42, so that the airflow from the second side of the mounting member 3 can be blown onto the heating element 42 through the ventilation hole 31, improving the heat dissipation effect at the position of the circuit board 41 where the heating element 42 is provided.

[0029] As shown in FIG. 2, in one possible embodiment, the heating element 42 is attached to the side of the circuit board 41 away from the mounting member 3, and a support member 5 is provided between the circuit board 41 and the mounting member 3, and the support member 5 is used to support the circuit board 41.

[0030] The support member 5 provides a gap between the circuit board 41 and the mounting member 3, and the airflow on the second side of the mounting member 3 can be blown into the gap between the circuit board 41 and the mounting member 3 through the ventilation hole 31.

[0031] A support member 5 is provided between the circuit board 41 and the mounting member 3, reducing the possibility that the circuit board 41 will block the ventilation hole 31, so that the airflow on the second side of the mounting member 3 is blown onto the circuit board 41 through the ventilation hole 31 and flows through the gap between the circuit board 41 and the mounting member 3, thereby improving the air flow speed on the side of the circuit board 41 facing the mounting member 3, and thereby improving the heat dissipation effect of the circuit board 41.

[0032] In one possible embodiment, the support member 5 may be a columnar structure, and the diameter of the support member 5 is small, which can support the circuit board 41 while reducing the obstruction to the airflow between the circuit board 41 and the mounting member 3, and further improve the heat dissipation efficiency for the circuit board 41.

[0033] As shown in FIG. 2, in one possible embodiment, the energy storage converter further includes a second heat-generating member 6, which is located on a side of the mounting member 3 away from the first heat-generating member 4 along the thickness direction Z of the mounting member 3.

[0034] The second heat generating member 6 is attached to the inner wall of the chamber 11 and is located on the blowing side of the fan 2, and the airflow blown out by the fan 2 can increase the airflow speed around the second heat generating member 6.

[0035] The first heat-generating member 4 and the second heat-generating member 6 are both located on the blowing side of the fan 2, and the second heat-generating member 6 is located on the side of the mounting member 3 that is away from the first heat-generating member 4 along the thickness direction Z of the mounting member 3. As a result, the fan 2 dissipates heat from the first heat-generating member 4 and the second heat-generating member 6 simultaneously, improving the utilization rate of the space within the chamber 11 and being advantageous for miniaturizing the energy storage converter.

[0036] 4 and 5, in one possible embodiment, the fan 2 is located on one side of the mounting member 3 in the longitudinal direction Y, and a plurality of ventilation holes 31 are provided in the mounting member 3, and the plurality of ventilation holes 31 are provided at intervals along the width direction X of the mounting member 3. The ventilation holes 31 and the second heat-generating member 6 are provided in order along the air blowing direction of the fan 2.

[0037] The first heat-generating member 4 is provided on a first side of the mounting member 3, and a plurality of ventilation holes 31 are provided at intervals in the width direction X of the mounting member 3, which increases the range through which the airflow on the second side of the mounting member 3 flows to the first heat-generating member 4, thereby improving the heat dissipation efficiency for the first heat-generating member 4. The ventilation holes 31 and the second heat-generating member 6 are provided in this order along the airflow direction of the fan 2, and the airflow on the second side of the mounting member 3 passes through the ventilation holes 31 before being blown onto the second heat-generating member 6, thereby lowering the temperature of the airflow passing through the ventilation holes 31 and blown onto the first heat-generating member 4, thereby improving the heat dissipation effect for the first heat-generating member 4.

[0038] 4 and 5, in one possible embodiment, a plurality of ventilation holes 31 are provided in the mounting member 3, and the plurality of ventilation holes 31 are provided at intervals along the longitudinal direction Y of the mounting member 3. The ventilation holes 31 and the second heat generating member 6 are provided side by side along a direction perpendicular to the air blowing direction of the fan 2.

[0039] A plurality of ventilation openings 31 are provided along the length direction Y of the mounting member 3 and are located within the airflow range of the fan 2, and the range in which the airflow on the second side of the mounting member 3 flows to the first heat-generating member 4 is increased along the length direction Y of the mounting member 3, thereby improving the heat dissipation efficiency for the first heat-generating member 4. The air guide member 32 is provided on a side wall of the ventilation openings 31 and is bent in a direction approaching the second heat-generating member 6 and perpendicular to the airflow direction of the fan 2, and the ventilation openings 31 and the second heat-generating member 6 are provided side by side, thereby reducing the possibility of interference between the air guide member 32 and the second heat-generating member 6.

[0040] In one possible embodiment, the ventilation opening 31 may be provided at another position on the mounting member 3 within the air blowing range of the fan 2, as long as the air guide member 32 provided on the side wall of the ventilation opening 31 does not interfere with the second heat-generating member 6, and the heat dissipation effect on the first heat-generating member 4 can be further improved.

[0041] As shown in Figures 6 and 7, in one possible embodiment, the air guide member 32 provided in the ventilation opening 31 is inclined in a direction away from the first heat-generating member 4, and the included angle between the air guide member 32 and the mounting member 3 is α, where α is 132° to 138°.

[0042] The first heat generating member 4 is attached to the first side of the mounting member 3, and the air guide member 32 is inclined in a direction away from the first heat generating member 4, so that the air guide member 32 protrudes to the second side of the mounting member 3 and can guide the airflow on the second side of the mounting member 3 to the first side of the mounting member 3, improving the air flow speed on the first side of the mounting member 3 and further improving the heat dissipation effect on the first heat generating member 4. If the included angle between the air guide member 32 and the mounting member 3 is large, the length of the air guide member 32 protruding to the second side of the mounting member 3 is reduced, and the second side of the mounting member 3 reduces the flow rate of the airflow flowing into the first side of the mounting member 3 along the air guide member 32, which leads to a decrease in the heat dissipation effect on the first heat generating member 4. If the included angle between the air guide member 32 and the mounting member 3 is small, the air guide member 32 affects the flow rate of the airflow that comes into contact with the air guide member 32 on the second side of the mounting member 3, and further reduces the flow rate of the airflow that flows into the first side of the mounting member 3, which leads to a reduction in the heat dissipation effect on the first heat-generating member 4. Therefore, the included angle α between the air guide member 32 and the airflow direction of the fan 2 may be 132°, 135°, 138°, etc., and is preferably 135°, which allows a sufficient amount of airflow to flow from the second side of the mounting member 3 to the first side of the mounting member 3 along the air guide member 32, and by reducing the effect on the flow rate of the airflow, the heat dissipation effect on the first heat-generating member 4 can be improved.

[0043] As shown in FIG. 8, in one possible embodiment, an extension portion 7 is provided at one end of the air guide member 32 away from the mounting member 3, and the extension portion 7 extends in a direction close to the fan 2 and away from the first heat-generating member 4.

[0044] By providing an extension portion 7 at the end of the air guide member 32, the size by which the air guide member 32 protrudes toward the second side of the mounting member 3 can be extended, and a portion of the air flow on the second side of the mounting member 3 can be brought into contact with the extension portion 7. The air flows along the extension portion 7 into the air guide member 32 and then to the first side of the mounting member 3, thereby improving the air flow rate between the first heat-generating member 4 and the mounting member 3 and further improving the heat dissipation effect on the first heat-generating member 4.

[0045] As shown in FIG. 8, in one possible embodiment, the extension portion 7 provided at the end of the air guide member 32 extends in a direction approaching the fan 2, and the included angle between the straight line on which the extension portion 7 is located and the mounting member 3 is θ, where θ is between 0° and 90°.

[0046] The extension portion 7 extends the size of the air guide member 32 protruding to the second side of the mounting member 3 so that the airflow on the second side of the mounting member 3 can flow along the extension portion 7 to the air guide member 32. The included angle θ between the straight line on which the extension portion 7 is located and the mounting member 3 may be 0°, 45°, 90°, etc., and is preferably 45°. If the included angle θ between the straight line on which the extension portion 7 is located and the mounting member 3 is smaller than 0°, the contact area between the air guide member 32 and the airflow on the second side of the mounting member 3 is reduced, and the flow rate of the airflow flowing from the ventilation opening 31 to the first side of the mounting member 3 is reduced. If the included angle θ between the straight line on which the extension portion 7 is located and the mounting member 3 is larger than 90°, the airflow on the second side of the mounting member 3 cannot flow along the extension portion 7 to the air guide member 32, and the flow rate of the airflow on the second side of the mounting member 3 is affected.

[0047] In one possible embodiment, the cross section of the extension 7 perpendicular to the air blowing direction of the fan 2 is arc-shaped.

[0048] The extension portion 7 is used to conduct the airflow on the second side of the mounting member 3 to the air guide member 32, and the cross section of the extension portion 7 may be rectangular, V-shaped, etc. When the included angle between the extension portion 7 and the air blowing direction of the fan 2 is the same, the contact area of ​​the airflow between the extension portion 7 and the second side of the mounting member 3 can be improved, and the flow rate of the airflow flowing from the second side of the mounting member 3 to the first side of the mounting member 3 can be further improved.

[0049] As shown in FIG. 9 , an embodiment of the present application further provides a heat dissipation system, which is applied to the energy storage converter described in any one of the above paragraphs, and the heat dissipation system includes a first heat dissipation passage 8 and a second heat dissipation passage 9, the first heat dissipation passage 8 is located on a side of the mounting member 3 close to the first heat-generating member 4 along the thickness direction Z of the mounting member 3, and the second heat dissipation passage 9 is located on a side of the mounting member 3 away from the first heat-generating member 4, and the first heat dissipation passage 8 and the second heat dissipation passage 9 are connected via a ventilation hole 31 so that the airflow in the second heat dissipation passage 9 enters the first heat dissipation passage 8 through the ventilation hole 31.

[0050] The mounting member 3 is located on the blowing side of the fan 2, and the mounting member 3 can divide the airflow blown out from the fan 2 into two parts along the thickness direction Z of the mounting member 3 to form a first heat dissipation passage 8 and a second heat dissipation passage 9. By providing the ventilation opening 31 and the air guide member 32 in the mounting member 3, the first heat dissipation passage 8 is connected to the second heat dissipation passage 9, and the airflow in the second heat dissipation passage 9 can be made to flow into the first heat dissipation passage 8, thereby improving the flow rate of the airflow in the first heat dissipation passage 8 and improving the heat dissipation capacity of the first heat dissipation passage 8.

[0051] The first heat-generating member 4 and the second heat-generating member 6 in the energy storage converter are placed in the first heat dissipation passage 8 and the second heat dissipation passage 9, respectively, and the first heat-generating member 4 and the second heat-generating member 6 are dissipated heat by the airflow blown into the first heat dissipation passage 8 and the second heat dissipation passage 9 via the fan 2. The heat dissipation system enables the first heat-generating member 4 and the second heat-generating member 6 to be dissipated heat simultaneously via one fan 2, thereby improving the heat dissipation efficiency and space utilization rate in the energy storage converter.

[0052] The embodiment of the present application relates to an energy storage converter and a heat dissipation system, and the heat dissipation system is applied to the energy storage converter. The energy storage converter includes a housing 1, a chamber 11 is provided in the housing 1, a fan 2, a mounting member 3 and a first heat generating member 4 are provided in the chamber 11, the fan 2 is attached to the inner wall of the chamber 11, the mounting member 3 is also attached to the inner wall of the chamber 11 and is located on the blowing side of the fan 2, the first heat generating member 4 is attached to one side of the mounting member 3 along the thickness direction Z of the mounting member 3, the fan 2 can improve the air flow speed on both sides of the thickness direction Z of the mounting member 3, and can further improve the air flow speed around the first heat generating member 4, which is advantageous to improving the heat dissipation effect for the first heat generating member 4. An air vent 31 is provided in the mounting member 3, and an air guide member 32 is provided on the side of the air vent 31 away from the fan 2. The air guide member 32 is bent toward the side away from the first heat-generating member 4 and extends in a direction approaching the fan 2, so that the airflow on the other side of the mounting member 3 can flow along the air guide member 32 to the side of the mounting member 3 where the first heat-generating member 4 is provided, further improving the heat dissipation effect on the first heat-generating member 4.
