[0019] In order to better understand the technical solution of the present invention, the following detailed description of embodiments of the present invention will be 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, and are not all of the embodiments. Based on the embodiments of the present invention, all other embodiments that a person skilled in the art can obtain without any inventive effort fall within the scope of protection of the present invention.

For example, A and / or B can indicate three kinds of situations: 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 when referring to an element being connected "up" or "down" to another element, it may not only be directly connected "up" or "down" to the other element, but also indirectly connected "up" or "down" to the other element via an intermediate element.

[0024] As shown in FIGS. 1, 2, and 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 within the housing 1. The fan 2 is located in the chamber 11 and attached to an inner wall of the chamber 11. The mounting member 3 is connected 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 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 that penetrates the mounting member 3 along the thickness direction Z. An air guide member 32 is provided on a side wall of the air vent 31 that is away from the fan 2. The air guide member 32 is bent along the thickness direction Z of the mounting member 3 in a direction away from the first heat-generating member 4 and extends to the 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 becomes too high, the energy storage converter will not operate normally. Attaching the first heat-generating member 4 to the outlet side of the fan 2 increases the airflow velocity around the first heat-generating member 4, further improving the heat dissipation effect from the first heat-generating member 4 and thereby improving the heat dissipation effect within the energy storage converter. The mounting member 3 has a first side and a second side facing each other along the thickness direction Z of the mounting member 3, and the first heat-generating member 4 is attached to the first side of the mounting member 3. The mounting member 3 is located on the outlet side of the fan 2 and divides the airflow blown out from the fan 2 into two parts: one is blown toward the first side of the mounting member 3 where the first heat-generating member 4 is located, and the other is blown toward the second side of the mounting member 3 where the first heat-generating member 4 is not located. Due to limitations on the size of the energy storage converter and 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. Therefore, 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 are connected to 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 a ventilation hole 31 is provided at a position on 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 that is 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 emits heat, causing a rise in temperature at the position where the heating element 42 is located on the circuit board 41. The ventilation opening 31 is located at a position corresponding to the heating element 42, allowing the airflow from the second side of the mounting member 3 to be blown onto the heating element 42 through the ventilation opening 31, improving the heat dissipation effect at the position where the heating element 42 is located on the circuit board 41.

[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 opening 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, improving the air flow rate 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 may be small, which can support the circuit board 41 while reducing the obstruction to 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 simultaneously dissipates heat from the first heat-generating member 4 and the second heat-generating member 6, improving the utilization rate of the space within the chamber 11 and 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 this 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, increasing the area over which the airflow on the second side of the mounting member 3 flows toward 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 toward the second heat-generating member 6, reducing the temperature of the airflow passing through the ventilation holes 31 and blown toward 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 openings 31 are provided in the mounting member 3, and the plurality of ventilation openings 31 are provided at intervals along the longitudinal direction Y of the mounting member 3. The ventilation openings 31 and the second heat-generating member 6 are provided side by side along a direction perpendicular to the airflow 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, which increases the area along the length direction Y of the mounting member 3 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 air guide member 32 is provided on the side wall of the ventilation openings 31 and is bent in a direction approaching the second heat-generating member 6, and is perpendicular to the airflow direction of the fan 2. The ventilation openings 31 and the second heat-generating member 6 are arranged side by side, which reduces 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, thereby further improving the heat dissipation effect on the first heat-generating member 4.

[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, which 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 for 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 that the air guide member 32 protrudes to the second side of the mounting member 3 will be reduced, and the second side of the mounting member 3 will reduce the amount of airflow flowing along the air guide member 32 into the first side of the mounting member 3, resulting in a reduced heat dissipation effect for 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 will affect 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, further reducing the flow rate of the airflow that flows into the first side of the mounting member 3, thereby reducing 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 along the air guide member 32 from the second side of the mounting member 3 to the first side of the mounting member 3, 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 Figure 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 to the second side of the mounting member 3 can be extended, and part of the air flow on the second side of the mounting member 3 can be brought into contact with the extension portion 7, and by flowing along the extension portion 7 to the air guide member 32 and then to the first side of the mounting member 3, the air flow rate between the first heat-generating member 4 and the mounting member 3 is improved, and the heat dissipation effect on the first heat-generating member 4 is further improved.

[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 protrusion of the air guide member 32 toward 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 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 angle θ between the straight line on which the extension portion 7 is located and the mounting member 3 is less 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, thereby reducing the flow rate of the airflow flowing from the ventilation opening 31 to the first side of the mounting member 3. If the angle θ between the straight line on which the extension portion 7 is located and the mounting member 3 is greater 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 airflow 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, or the like. If the included angle between the extension portion 7 and the airflow 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 increased, 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 increased.

[0049] As shown in Figure 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 opening 31 so that the airflow in the second heat dissipation passage 9 enters the first heat dissipation passage 8 through the ventilation opening 31.

[0050] The mounting member 3 is located on the outlet side of the fan 2, and 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 directed into the first heat dissipation passage 8, thereby improving the flow rate of the airflow in the first heat dissipation passage 8 and 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 installed 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 allows the first heat-generating member 4 and the second heat-generating member 6 to dissipate heat simultaneously via one fan 2, improving the heat dissipation efficiency and space utilization rate within the energy storage converter.

[0052] The present embodiment 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 disposed within the housing 1, a fan 2, a mounting member 3, and a first heat-generating member 4 disposed within the chamber 11, the fan 2 attached to an inner wall of the chamber 11, the mounting member 3 also attached to the inner wall of the chamber 11 and positioned on the blowing side of the fan 2, and the first heat-generating member 4 attached to one side of the mounting member 3 along the thickness direction Z of the mounting member 3, the fan 2 can increase the airflow speed on both sides of the thickness direction Z of the mounting member 3 and further increase the airflow speed around the first heat-generating member 4, which is advantageous for 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 on 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 on 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.
