Description

Technical Field

[0001] The utility model relates to the field of heat dissipation, and particularly relates to a heat dissipation energy storage machine. Background Art

[0002] Energy storage products generally adopt natural heat dissipation. Generally, radiators are arranged on the energy storage products. The heat dissipation teeth of the radiators extend vertically, and cold air flows from bottom to top to take away the heat transferred from the energy storage products to the radiators. When multiple energy storage products are stacked vertically, the air inlet of the upper radiator is the air outlet of the lower radiator. Therefore, the temperature of the air inlet of the radiator closer to the upper part is higher, resulting in low heat dissipation efficiency of the uppermost energy storage product. Summary of the Utility Model

[0013] Based on Technical Solution 5, there is also provided Technical Solution 9.

[0014] Based on any one of Technical Solutions 1 to 9, there is also provided Technical Solution 10. In Technical Solution 10 and its related embodiments, each heat dissipation module is arranged at intervals in the Z-axis direction.

[0015] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solutions and their preferred embodiments of the present invention have the following beneficial effects due to the following technical means:

[0016] In Technical Solution 1 and its preferred embodiments, since the heat dissipation cavity structure is located on one side of the component to be cooled along the Y-axis direction, the component to be cooled can still be maintained on the side away from the installation wall, and the overall length of the heat dissipation energy storage machine in the X-axis direction is small. The heat dissipation cavity structure is spaced from the installation wall along the X-axis direction. A number of heat dissipation fins extending along the Y-axis direction and inclined relative to the Z-axis direction are provided in the heat dissipation cavity. A number of through holes are respectively provided on both sides of the heat dissipation cavity along the X-axis direction. Therefore, the through holes on the side away from the installation wall can intake air, and the through holes on the side close to the installation wall can exhaust air. Since the heat dissipation fins are inclined relative to the perpendicular Z-axis direction, the hot air is discharged obliquely upward and flows upward through the space between the heat dissipation cavity structure and the installation wall. Therefore, the hot air in the lower heat dissipation cavity structure is far from the air inlet of the upper heat dissipation cavity structure, and the heat dissipation cavity structure basically discharges air obliquely upward, and it is not easy to generate a thermal cascade effect. In addition, since the side away from the heat dissipation wall is the air intake side, there will be no hot air flowing towards the user, and the user experience is good. And since the heat dissipation cavity does not intake air in the Y-axis direction, the heat dissipation energy storage machine has low requirements for the installation space in the Y-axis direction.

[0017] In Technical Solution 2 and its preferred embodiments, the first side wall is close to the higher end of the heat dissipation fins, and the second side wall of the heat dissipation cavity along the X-axis direction is close to the lower end of the heat dissipation fins. Since the density of hot air is small, the air flow is easy to enter from the through holes of the second side wall and discharge from the through holes of the first side wall, which further facilitates the intake of air by the second side wall and the exhaust of air by the first side wall, improving the user experience. Since the through hole at the uppermost part of the second side wall is lower than the through hole at the uppermost part of the first side wall, it is more conducive to the hot air discharged from the heat dissipation fins extending to the top of the heat dissipation part to flow towards the through holes of the first side wall, improving the air exhaust efficiency.

[0018] In Technical Solution 3 and its preferred embodiments, since the through holes of the first side wall are arranged along the Z-axis direction to the top of the heat dissipation cavity, and the through holes of the second side wall are arranged along the Z-axis direction to the top of the heat dissipation part, the hot air discharged from the heat dissipation fins extending to the top of the heat dissipation part is easy to directly flow towards the through holes of the first side wall without colliding with the top wall of the heat dissipation cavity, with small wind resistance and high air exhaust efficiency. And since the through holes of the second side wall are arranged along the Z-axis direction to the top of the heat dissipation part, when the second side wall intakes air and the first side wall exhausts air, the through holes of the first side wall corresponding to the air passing interval basically only exhaust the hot air discharged from the heat dissipation fins extending to the top of the heat dissipation part, thereby further reducing the wind resistance of the heat dissipation fins above the heat dissipation part, and thus improving the heat dissipation efficiency.

[0019] In Technical Solution 4 and its preferred embodiments, the interval value of the air passing interval along the Z-axis direction is greater than the product of the number of heat dissipation fins extending to the top of the heat dissipation part and the first interval. Therefore, the hot air discharged from the heat dissipation fins extending to the top of the heat dissipation part can directly flow towards the through holes of the first side wall without colliding with the top wall of the heat dissipation cavity, with small wind resistance and high air exhaust efficiency.

[0020] In Technical Solution Five and its preferred embodiments, the heat dissipation plate is provided, which is easy to transfer the heat of the component to be cooled to the heat sink and is easy to process.

[0021] In Technical Solution Six and its preferred embodiments, the free ends of the heat sinks abut against the main wall, which is conducive to forming an inclined extending channel between adjacent heat sinks. Compared with forming a gap between the main wall and the free ends of the heat sinks, it is more conducive to the air flow flowing from the through holes on the second side wall to the through holes on the first side wall, with high air outlet efficiency, and the hot air discharged from the gap between the lower heat sinks is not easy to pass upward through the upper heat sinks, improving the heat dissipation efficiency.

[0022] In Technical Solution Seven and its preferred embodiments, the top ends of the heat dissipation parts are flush along the Z-axis direction, which is conducive to processing, so that there can be more non-airflow spaces in the air passing interval, which is conducive to air outlet.

[0023] In Technical Solution Eight and its preferred embodiments, both ends of the heat dissipation part along the X-axis direction are flush along the X-axis direction, which is conducive to processing. The heat dissipation part is spaced from both the first side wall and the second side wall along the X-axis direction, and when the second side wall intakes air and the first side wall discharges air, the air resistance is small and the air outlet efficiency is high.

[0024] In Technical Solution Nine and its preferred embodiments, the bottom ends of the heat dissipation parts are flush along the Z-axis direction, which is conducive to processing. The bottom ends of the heat dissipation parts are spaced from the bottom wall of the heat dissipation cavity along the Z-axis direction. Therefore, the cold air from the through holes on the second side wall can flow into the space between the bottom ends of the heat dissipation parts and the bottom wall of the heat dissipation cavity, and then flow into the gaps between the bottom heat sinks, which is conducive to air intake in the gaps between the bottom heat sinks.

[0025] In Technical Solution Ten, the heat dissipation modules are arranged at intervals along the Z-axis direction, which is conducive to the installation of the component to be cooled and also conducive to preventing the hot air discharged from the lower heat dissipation cavity structure from entering the upper heat dissipation cavity structure.

[0038] In the claims and the description except for the embodiments, the terms "X-axis direction", "Y-axis direction", and "Z-axis direction" only mean that the features having one of the above directions are perpendicular to the features having another direction, and it is not required that they must be implemented in accordance with the "X-axis direction", "Y-axis direction", and "Z-axis direction" introduced in the embodiments. In the embodiments, the X-axis direction is perpendicular to the Y-axis direction and also perpendicular to the Z-axis direction. Among them, the X-axis direction can be divided into left and right, the Y-axis direction can be divided into front and back, and the Z-axis direction can be divided into up and down.

[0039] See Figure 1 , Figure 1 shows a heat dissipation energy storage machine for being installed on an installation wall 10. The installation wall 10 is perpendicular to the horizontal X-axis direction and extends along the vertical Z-axis direction. The heat dissipation energy storage machine includes a plurality of heat dissipation modules 20 arranged at intervals along the Z-axis direction.

[0040] The heat dissipation module 20 includes a component to be dissipated 30 and a heat dissipation cavity structure 40 for dissipating heat from the component to be dissipated 30. In this embodiment, the component to be dissipated 30 is an energy storage module. The component to be dissipated 30 is installed on the installation wall 10. The heat dissipation cavity structure 40 is located on one side of the component to be dissipated 30 along the Y-axis direction and forms a gap along the X-axis direction with the installation wall 10.

[0041] The heat dissipation cavity is provided with a heat dissipation plate 41 and a heat dissipation part. The heat dissipation plate 41 is perpendicular to the horizontal Y-axis direction. The heat dissipation part is provided with a plurality of heat dissipation fins 50. Each heat dissipation fin 50 extends from the heat dissipation plate 41 along the Y-axis direction in parallel with each other and is inclined relative to the vertical Z-axis direction. A first spacing is formed between adjacent heat dissipation fins 50; the top ends of the heat dissipation part are flush along the Z-axis direction, the bottom ends of the heat dissipation part are flush along the Z-axis direction, and both ends of the heat dissipation part along the X-axis direction are flush along the X-axis direction.

[0042] An air passing interval 01 is formed between the top end of the heat dissipation part and the top wall 44 of the heat dissipation cavity; the first side wall 42 of the heat dissipation cavity along the X-axis direction is close to the higher end of the heat dissipation fins 50, the second side wall 43 of the heat dissipation cavity along the X-axis direction is close to the lower end of the heat dissipation fins 50. Both the first side wall 42 and the second side wall 43 are perpendicular to the X-axis direction, and the heat dissipation part is spaced from both the first side wall 42 and the second side wall 43 along the X-axis direction. Both the first side wall 42 and the second side wall 43 are provided with a plurality of through holes 46. Among them, the through holes 46 of the first side wall 42 are arranged along the Z-axis direction to the top end of the heat dissipation cavity, and the through holes 46 of the second side wall 43 are arranged along the Z-axis direction to the top end of the heat dissipation part. The interval value of the air passing interval 01 along the Z-axis direction is greater than the product of the number of heat dissipation fins 50 extending to the top end of the heat dissipation part and the first spacing. Among them, the first side wall 42 is close to the installation wall 10 and forms a gap with the installation wall 10.

[0043] The heat dissipation cavity is further provided with a bottom wall 45 perpendicular to the Z-axis direction. The bottom end of the heat dissipation part is spaced from the bottom wall 45 of the heat dissipation cavity along the Z-axis direction.

[0044] The heat dissipation cavity is further provided with a main wall 47 perpendicular to the Y-axis direction. The main wall 47 faces the heat dissipation plate 41, and the free ends of the heat dissipation fins 50 abut against the main wall 47.

[0045] In this embodiment, the first side wall 42 is close to the higher end of the heat dissipation fins 50, and the second side wall 43 of the heat dissipation cavity along the X-axis direction is close to the lower end of the heat dissipation fins 50. Since the density of hot air is small, the air flow is easily introduced through the through holes 46 of the second side wall 43 and discharged through the through holes 46 of the first side wall 42. Since the through holes 46 of the second side wall 43 are arranged along the Z-axis direction to the top of the heat dissipation part, and the through holes 46 of the first side wall 42 are arranged along the Z-axis direction to the top of the heat dissipation cavity, the interval value of the air passage interval 01 along the Z-axis direction is greater than the product of the number of heat dissipation fins 50 extending to the top of the heat dissipation part and the first interval. Therefore, the hot air discharged from the heat dissipation fins 50 extending to the top of the heat dissipation part can directly flow to the through holes 46 of the first side wall 42 without colliding with the top wall 44 of the heat dissipation cavity, with small wind resistance and high air outlet efficiency. Moreover, since the through holes 46 of the second side wall 43 are arranged along the Z-axis direction to the top of the heat dissipation part, when the second side wall 43 intakes air and the first side wall 42 discharges air, the through holes 46 of the first side wall 42 corresponding to the air passage interval 01 basically only discharge the hot air discharged from the heat dissipation fins 50 extending to the top of the heat dissipation part, thereby further reducing the wind resistance of the heat dissipation fins 50 above the heat dissipation part and improving the heat dissipation efficiency.

[0046] The free ends of the heat dissipation fins 50 abut against the main wall 47, which is beneficial to forming an inclined extension channel between adjacent heat dissipation fins 50. Compared with forming a spacing between the main wall 47 and the free ends of the heat dissipation fins 50, it is more beneficial for the air flow to flow from the through holes 46 of the second side wall 43 to the through holes 46 of the first side wall 42, with high air outlet efficiency, and the hot air discharged from the gaps between the lower heat dissipation fins 50 is not easily passed upward through the upper heat dissipation fins 50, improving the heat dissipation efficiency.

[0047] The top of the heat dissipation part is flush along the Z-axis direction, which is beneficial for processing, so that there can be more non-air passage spaces in the air passage interval 01, which is beneficial for air outlet. The two ends of the heat dissipation part along the X-axis direction are flush along the X-axis direction, which is beneficial for processing. The heat dissipation part is spaced from the first side wall 42 and the second side wall 43 along the X-axis direction, and it also makes the wind resistance small and the air outlet efficiency high when the second side wall 43 intakes air and the first side wall 42 discharges air. The bottom end of the heat dissipation part is flush along the Z-axis direction, which is beneficial for processing. The bottom end of the heat dissipation part is spaced from the bottom wall 45 of the heat dissipation cavity along the Z-axis direction. Therefore, the cold air of the through holes 46 of the second side wall 43 can flow into the space between the bottom end of the heat dissipation part and the bottom wall 45 of the heat dissipation cavity, and then flow into the gaps of the heat dissipation fins 50 at the bottom, which is beneficial for the gaps of the heat dissipation fins 50 at the bottom to intake air.

[0048] Since the heat dissipation cavity structure is located on one side of the component 30 to be cooled along the Y-axis direction, the component 30 can still be maintained on the side away from the mounting wall 10, and the overall length of the heat dissipation energy storage machine in the X-axis direction is small.

[0049] In this embodiment, the side where the second side wall 43 of the heat dissipation cavity structure 40 is located is the air inlet side, and the side where the first side wall 42 is located is the air outlet side, avoiding the first side wall 42 from taking in air. Since the heat dissipation fins 50 are inclined relative to the perpendicular Z-axis direction, the hot air is discharged obliquely upward and flows upward through the gap between the heat dissipation cavity structure and the mounting wall 10. Therefore, the hot air in the lower heat dissipation cavity structure is far from the air inlet of the upper heat dissipation cavity structure, and the heat dissipation cavity structure 40 basically discharges air obliquely upward, making it not easy to generate a thermal cascade effect. In addition, when the user maintains the energy storage machine, there will be no hot air flowing towards the user, providing a good user experience. Moreover, since the heat dissipation cavity does not intake air in the Y-axis direction, the heat dissipation energy storage machine has low requirements for the installation space in the Y-axis direction. The heat dissipation modules 20 are arranged at intervals along the Z-axis direction, which is beneficial to the installation of the component 30 to be cooled and also helps prevent the hot air discharged from the lower heat dissipation cavity structure 40 from entering the upper heat dissipation cavity structure 40.

[0050] The above description of the specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the inspiration of the present invention or the above embodiments, those of ordinary skill in the art, combined with common general knowledge, ordinary technical knowledge in the art, and / or existing technologies, can obtain modifications, equivalent replacements, or other improvements to the embodiments of the present invention or some of its technical features through logical analysis, reasoning, or limited experiments, which should all be included within the protection scope of the present invention.
