Mode for Carrying Out the Invention

[0018] The drawings herein are incorporated into the specification and form a part of the specification, showing embodiments consistent with the present invention and used to explain the mechanism of the present invention together with the specification.

[0019] To better understand the technical solution of the present invention, the following will detail the embodiments of the present invention with reference to the accompanying drawings.

[0020] It should be clear that the described embodiments are only some embodiments of the present application and not all embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without making inventive efforts shall fall within the protection scope of the present invention.

[0021] The terms used in the embodiments of the present invention are only for the purpose of explaining specific embodiments and are not intended to limit the present invention. The singular forms of "a kind", "the above-mentioned", and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0022] It should be understood that the term "and / or" used in this specification is only for explaining the relationship of related objects and indicates that three types of relationships are possible. For example, A and / or B can indicate three situations: A exists alone, A and B exist simultaneously, and B exists alone. Also, 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 "up," "down," "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 to the embodiments of the present invention. Furthermore, it should be noted in the context that when referring to one element being connected to the "up" or "down" of another element, it may not only be connected directly to the "up" or "down" of the other element, but may also be connected indirectly to the "up" or "down" of the other element via an intermediate element.

[0024] As shown in Figures 1, 2, and 3, an embodiment of the present invention provides an energy storage converter comprising a housing 1, a fan 2, a mounting member 3, and a heat-generating member 4. The housing 1 contains a chamber 11, 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 discharge 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 airflow velocity on both sides of the mounting member 3 along the thickness direction Z. The mounting member 3 includes a vent 31, which penetrates the mounting member 3 along the thickness direction Z, and a guide member 32 is provided on the side wall of the vent 31 that is spaced away from the fan 2. Along the thickness direction Z of the mounting member 3, the guide member 32 is bent in a direction away from the first heat-generating member 4 and extends toward the side closer to the fan 2.

[0025] During the operation of the energy storage converter, the first heat-generating element 4 releases heat. If the temperature of the first heat-generating element 4 becomes too high, the energy storage converter will not be able to operate normally. By attaching the first heat-generating element 4 to the outlet side of the fan 2, the airflow velocity around the first heat-generating element 4 is increased, further improving the heat dissipation effect on the first heat-generating element 4 and thus improving the heat dissipation effect within the energy storage converter. 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 element 4 is attached to the first side of the mounting member 3. The mounting member 3 is provided on the outlet side of the fan 2, and divides the airflow blown out from the fan 2 into two parts. A portion is blown onto the first side of the mounting member 3 where the first heat-generating element 4 is provided, and the remainder is blown onto the second side of the mounting member 3 where the first heat-generating element 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 airflow rate blown onto the first side of the mounting member 3 is smaller than the airflow rate blown onto the second side of the mounting member 3. Therefore, the mounting member 3 is provided with ventilation openings 31 such that both sides in the thickness direction Z of the mounting member 3 are in communication with each other, and the air guide member 32 can conduct the airflow from the second side of the mounting member 3 to the first side, thereby improving the airflow rate 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 Figure 2, in one possible embodiment, the first heating element 4 includes a circuit board 41 and a heating element 42, the heating element 42 being mounted on the circuit board 41, and a ventilation opening 31 is provided at a position on the mounting member 3 corresponding to the heating 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 separated from the mounting member 3.

[0028] The heat-generating element 42 may be an electronic element such as a relay. During the operation of the energy storage converter, the heat-generating element 42 releases heat, causing the temperature of the circuit board 41 at the location where the heat-generating element 42 is installed to rise. The ventilation opening 31 is located at a position corresponding to the heat-generating element 42, thereby allowing the airflow from the second side of the mounting member 3 to be blown onto the heat-generating element 42 through the ventilation opening 31, improving the heat dissipation effect at the location where the heat-generating element 42 is installed on the circuit board 41.

[0029] As shown in Figure 2, in one possible embodiment, the heating element 42 is mounted on 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 from 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 obstructs the ventilation opening 31. As a result, the airflow on the second side of the mounting member 3 is blown onto the circuit board 41 through the ventilation opening 31 and flows through the gap between the circuit board 41 and the mounting member 3, improving the airflow velocity on the side of the circuit board 41 facing the mounting member 3, 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, allowing it to support the circuit board 41 while reducing shielding from airflow between the circuit board 41 and the mounting member 3, thereby further improving the heat dissipation efficiency for the circuit board 41.

[0033] As shown in Figure 2, in one possible embodiment, the energy storage converter further includes a second heating element 6, the second heating element 6 located on the side of the mounting element 3 that is spaced apart from the first heating element 4 along the thickness direction Z of the mounting element 3.

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

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

[0036] As shown in Figures 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 the mounting member 3 is provided with a plurality of ventilation openings 31, which are spaced apart along the width direction X of the mounting member 3. The ventilation openings 31 and the second heat-generating member 6 are provided in order along the airflow direction of the fan 2.

[0037] The first heat-generating element 4 is provided on the first side of the mounting member 3, and multiple ventilation openings 31 are provided at intervals in the width direction X of the mounting member 3, thereby increasing the area over which the airflow from the second side of the mounting member 3 flows to the first heat-generating element 4 and improving the heat dissipation efficiency of the first heat-generating element 4. The ventilation openings 31 and the second heat-generating element 6 are provided in order along the airflow direction of the fan 2, so that the airflow from the second side of the mounting member 3 passes through the ventilation openings 31 before being blown onto the second heat-generating element 6, thereby lowering the temperature of the airflow that passes through the ventilation openings 31 and is blown onto the first heat-generating element 4 and improving the heat dissipation effect of the first heat-generating element 4.

[0038] As shown in Figures 4 and 5, in one possible embodiment, the mounting member 3 is provided with a plurality of ventilation openings 31, which are spaced apart along the longitudinal direction Y of the mounting member 3. The ventilation openings 31 and the second heat-generating member 6 are arranged side by side along a direction perpendicular to the airflow direction of the fan 2.

[0039] Multiple ventilation openings 31 are provided along the longitudinal direction Y of the mounting member 3 and are located within the airflow range of the fan 2. Along the longitudinal direction Y of the mounting member 3, the range over which the airflow from the second side of the mounting member 3 flows to the first heat-generating member 4 can be increased, 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 provided side by side, 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 location on the mounting member 3 within the airflow range of the fan 2, provided that 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 vent 31 is inclined in a direction away from the first heat generating member 4, and the 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 element 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 element 4, so that the air guide member 32 protrudes to the second side of the mounting member 3, allowing the airflow from the second side of the mounting member 3 to be guided to the first side of the mounting member 3, thereby improving the airflow velocity on the first side of the mounting member 3 and further improving the heat dissipation effect on the first heat-generating element 4. If the angle between the air guide member 32 and the mounting member 3 is large, the length of the air guide member 32 that protrudes to the second side of the mounting member 3 will decrease, and the flow rate of the airflow that flows along the air guide member 32 to the first side of the mounting member 3 will decrease, leading to a decrease in the heat dissipation effect on the first heat-generating element 4. If the angle between the air guide member 32 and the mounting member 3 is small, the air guide member 32 will affect the flow velocity of the airflow in contact with the air guide member 32 on the second side of the mounting member 3, further reducing the flow velocity of the airflow flowing into the first side of the mounting member 3, thereby reducing the heat dissipation effect on the first heat-generating member 4. Therefore, the angle α between the air guide member 32 and the airflow direction of the fan 2 may be 132°, 135°, 138°, etc., but is preferably 135°, so that an airflow of sufficient flow rate can 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 the effect on the airflow velocity can be reduced, thereby improving the heat dissipation effect on the first heat-generating member 4.

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

[0044] By providing an extended portion 7 at the end of the air guide member 32, the size to which the air guide member 32 protrudes to the second side of the mounting member 3 can be extended, allowing a portion of the airflow on the second side of the mounting member 3 to come into contact with the extended portion 7. Furthermore, as the air flows along the extended portion 7 to the air guide member 32 and then to the first side of the mounting member 3, the airflow velocity between the first heat-generating member 4 and the mounting member 3 is increased, further improving the heat dissipation effect on the first heat-generating member 4.

[0045] As shown in Figure 8, in one possible embodiment, the extension portion 7 provided at the end of the air guide member 32 extends in a direction toward the fan 2, and the angle between the line in 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 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., but 45° is preferred. 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°, it reduces the contact area between the air guide member 32 and the airflow on the second side of the mounting member 3, and reduces the flow rate of the airflow flowing into the first side of the mounting member 3 from the vent 31. 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 it also affects the flow velocity of the airflow on the second side of the mounting member 3.

[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 extended portion 7 is used to conduct the airflow from the second side of the mounting member 3 to the air guide member 32, and the cross-section of the extended portion 7 may be rectangular, V-shaped, or the like. When the angle between the extended portion 7 and the airflow direction of the fan 2 is the same, the contact area of ​​the airflow between the extended 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 Figure 9, an embodiment of the present invention further provides a heat dissipation system applicable to an energy storage converter described in any one of the above paragraphs, the heat dissipation system comprising a first heat dissipation passage 8 and a second heat dissipation passage 9, wherein the first heat dissipation passage 8 is located along the thickness direction Z of the mounting member 3 on the side of the mounting member 3 adjacent to the first heat generating member 4, and the second heat dissipation passage 9 is located on the 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 in communication via a vent 31 such that airflow in the second heat dissipation passage 9 enters the first heat dissipation passage 8 through the vent 31.

[0050] The mounting member 3 is located on the outlet side of the fan 2, and along the thickness direction Z of the mounting member 3, the mounting member 3 can divide the airflow blown out from the fan 2 into two parts, forming a first heat dissipation passage 8 and a second heat dissipation passage 9. By providing the mounting member 3 with a ventilation opening 31 and an air guide member 32, the first heat dissipation passage 8 can be 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 airflow rate 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 element 4 and the second heat-generating element 6 within the energy storage converter are placed in the first heat dissipation passage 8 and the second heat dissipation passage 9, respectively. The airflow blown into the first heat dissipation passage 8 and the second heat dissipation passage 9 via the fan 2 dissipates heat from the first heat-generating element 4 and the second heat-generating element 6. The heat dissipation system allows the first heat-generating element 4 and the second heat-generating element 6 to dissipate heat simultaneously via a single fan 2, improving the heat dissipation efficiency and space utilization rate within the energy storage converter.

[0052] Embodiments of the present invention relate to an energy storage converter and a heat dissipation system, wherein the heat dissipation system is applied to the energy storage converter. The energy storage converter includes a housing 1, a chamber 11 provided within the housing 1, a fan 2, a mounting member 3, and a first heat generating member 4 provided within the chamber 11, the fan 2 being attached to the inner wall of the chamber 11, the mounting member 3 being attached to the inner wall of the chamber 11 and located on the discharge side of the fan 2, the first heat generating member 4 being attached to one side of the mounting member 3 along the thickness direction Z of the mounting member 3, the fan 2 being able to improve the airflow velocity on both sides of the mounting member 3 in the thickness direction Z, and further improving the airflow velocity around the first heat generating member 4, which is advantageous for improving the heat dissipation effect on the first heat generating member 4. A ventilation opening 31 is provided on the mounting member 3, and an air guide member 32 is provided on the side of the ventilation opening 31 that is away from the fan 2. The air guide member 32 is bent toward the side that is away from the first heat-generating member 4 and extends toward the fan 2, so that the airflow on the other side of the mounting member 3 can flow along the air guide member 32 toward the side of the mounting member 3 where the first heat-generating member 4 is located, further improving the heat dissipation effect on the first heat-generating member 4.
