[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0042] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore, should not be understood as a limitation on the present invention.
[0043] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In the description of the implementation method, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.
[0044] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
[0045] In the description of the present invention, unless otherwise specified, "plurality" means two or more. Unless otherwise specified, the numerical range herein includes not only the entire range within its two endpoints, but also several sub-ranges contained therein.
[0046] The utility model provides a waterproof heat dissipation structure, such as Figures 1 to 5 As shown, the waterproof heat dissipation structure includes a box body 1 and a first louver 2 .
[0047] The inner side of the box body 1 forms an inner cavity for installing the circuit module 5. A first window 11 is provided on the side wall of the box body 1, and the heat generated by the circuit module 5 can be dissipated through the first window 11. The first shutter 2 is provided in the first window 11, which can play a waterproof role and prevent water outside the box body 1 from entering the first window 11 and causing the circuit module 5 to be damaged by moisture.
[0048] The edge of the first window 11 is surrounded by a first waterproof platform 12 . The first waterproof platform 12 forms a first drainage slope 121 at the bottom edge of the first window 11 . The first drainage slope 121 slopes downward from the inside to the outside.
[0049] It should be noted that, in order to make this article clear and concise, the waterproof heat dissipation structure takes the side close to the inner cavity of the box body 1 as the inner side, and takes the side away from the inner cavity of the box body 1 as the outer side.
[0050] The first waterproof platform 12 provides waterproofing for the edges of the first window 11. Water drops blocked by the first blinds 2 fall onto the first drainage slope 121, and flow along the first drainage slope 121 to the outside of the box body 1, thereby preventing water from accumulating at the bottom of the first window 11.
[0051] The electric control box in the prior art is usually limited by the waterproof problem, resulting in a small heat dissipation window and poor heat dissipation effect. In the waterproof heat dissipation structure provided by the utility model, the first louver 2 and the first waterproof platform 12 play a sufficient waterproof role for the first window 11, and the first window 11 can expand the area, improve the heat dissipation efficiency of the circuit module 5, extend the service life of the circuit module 5, reduce the failure rate of the product, ensure product quality, and save later maintenance costs.
[0052] In detail, Figure 3 As shown, the first louver 2 includes a plurality of first water retaining pieces 21 arranged in the height direction and extending transversely, the opposite ends of the first water retaining pieces 21 are respectively connected to the edges of the first window 11, and the first water retaining pieces 21 are inclined downward from the inside to the outside. The opposite ends of the first water retaining pieces 21 can be specifically connected to the surfaces opposite to the left and right edges of the first window 11.
[0053] The water droplets on the first water baffle 21 can drip to the outside of the box body 1 along the inclined direction of the first water baffle 21. There is a gap between any two first water baffles 21 adjacent to each other, so that air can circulate inside and outside the box body 1 to ensure the heat dissipation effect.
[0054] In two first water retaining plates 21 adjacent to each other, the bottom of the upper first water retaining plate 21 may be flush with the top of the lower first water retaining plate 21, or the upper first water retaining plate 21 and the lower first water retaining plate 21 may partially overlap in the height direction. The present invention does not limit this.
[0055] In some specific embodiments, Figure 3 As shown, the inner edge of the first water retaining sheet 21 extends upward to form an upper vertical surface 211. The outer edge of the first water retaining sheet 21 extends downward to form a lower vertical surface 212. The upper vertical surface 211 and the lower vertical surface 212 have a better water retaining effect, and are conducive to reducing the width of the first water retaining sheet 21, so that the box body 1 has a compact structure.
[0056] In some embodiments, Figure 2 and Figure 5 As shown, the first waterproof platform 12 is constructed to bulge toward the outside of the box body 1, and the first waterproof platform 12 forms an avoidance groove 122 on the inner side of the box body 1 that can avoid the electronic components of the circuit module 5, so that the box body 1 has a compact structure and can make the electronic components closer to the first blind 2, shortening the heat dissipation path, which is beneficial to improving the heat dissipation efficiency.
[0057] In some embodiments, the first drainage slope 121 extends from the bottom edge of the first window 11 to the outer edge of the first waterproof platform 12. In some embodiments, the inclination angle between the first drainage slope 121 and the horizontal plane is set between 10° and 45°, such as 15°, 20°, 30°, etc.
[0058] The first waterproof platform 12 and the box body 1 can be an integrated structure. The first blind 2 can be arranged in the first window 11 of the box body 1 by bonding, fastener connection, snap connection or integrated connection.
[0059] In some embodiments, the box body 1 is provided with a second window 13, and a second shutter 3 is provided in the second window 13. Adding the second window 13 to the box body 1 can expand the heat dissipation area and further increase the heat dissipation efficiency of the circuit module 5. The second shutter 3 can play a waterproof role, preventing water outside the box body 1 from entering the second window 13 and causing damage to the circuit module 5.
[0060] In some embodiments, a second drainage slope 131 extending downward from the inside to the outside is formed at the bottom of the second window 13. Water drops blocked by the second louver 3 fall onto the second drainage slope 131, and the water drops flow along the second drainage slope 131 to the outside of the box body 1, thereby preventing water from accumulating at the bottom of the second window 13.
[0061] In some embodiments, the edge of the second window 13 forms a second waterproof platform 14, and the second waterproof platform 14 at least surrounds the top edge and both side edges of the second window 13. The second waterproof platform 14 plays a waterproof role for the edge of the second window 13.
[0062] In a specific embodiment, Figure 1 and Figure 4 As shown, the second waterproof platform 14 can be a convex strip protruding from the edge of the second window 13 , and the second waterproof platform 14 is constructed as a door-shaped structure, surrounding the top edge and the left and right side edges of the second window 13 .
[0063] The second blinds 3 and the second waterproof platform 14 can provide sufficient waterproof effect for the second window 13 .
[0064] Specifically, the second shutter 3 includes a plurality of second water retaining pieces 31 arranged in the height direction and extending transversely, the opposite ends of the second water retaining pieces 31 are respectively connected to the edges of the second window 13, and the second water retaining pieces 31 are inclined downward from the inside to the outside. The two ends of the second water retaining piece 31 are specifically connected to the opposite surfaces of the left and right edges of the second window 13.
[0065] The water drops on the second water retaining sheet 31 can fall to the outside of the box body 1 along the inclined direction of the second water retaining sheet 31. There is a gap between any two second water retaining sheets 31 adjacent to each other, so that air can circulate inside and outside the box body 1 to ensure the heat dissipation effect.
[0066] In two upper and lower adjacent second water retaining pieces 31, the bottom of the upper second water retaining piece 31 may be flush with the top of the lower second water retaining piece 31, or the upper second water retaining piece 31 and the lower second water retaining piece 31 may partially overlap in the height direction. The present invention does not limit this.
[0067] The second waterproof platform 14 and the box body 1 can be an integrated structure. The second blind 3 can be arranged in the second window 13 of the box body 1 by bonding, fastener connection, snap connection or integrated connection.
[0068] In some embodiments, the box body 1 is further provided with a mounting opening 15, and a heat sink 4 is provided in the mounting opening 15. Part of the heat generated by the circuit module 5 can be dissipated outside the box body 1 through the heat sink 4, further improving the heat dissipation efficiency of the box body 1. Providing the mounting opening 15 can improve the efficiency of transferring the heat of the circuit module 5 to the heat sink 4.
[0069] The installation opening 15 can be located on the side wall, top or bottom of the box body 1. Figure 2 In the specific embodiment shown, the installation opening 15 is arranged on the side wall of the box body 1 , and the radiator 4 blocks the installation opening 15 to prevent water from entering the installation opening 15 .
[0070] The heat sink 4 includes a base plate 41 and a plurality of heat sinks 42 connected to the outside of the base plate 41. The base plate 41 fits in the mounting opening 15 and covers the mounting opening 15. The plurality of heat sinks 42 extend to the outside of the mounting opening 15 to dissipate heat out of the box body 1.
[0071] The heat sink 4 can be installed in the installation opening 15 of the box body 1 by means of snap connection, bonding, fastener connection, etc., and the present invention does not limit this.
[0072] The first window 11, the second window 13 and the mounting opening 15 can all be arranged on the side wall of the box body 1. Specifically, the first window 11, the second window 13 and the mounting opening 15 are arranged horizontally on the side wall of the box body 1, and the first window 11, the second window 13 and the mounting opening 15 extend in the height direction respectively. The power components on the circuit module 5 that generate more heat can correspond to the positions of the first window 11, the second window 13 and the mounting opening 15 respectively, so as to improve the heat dissipation efficiency.
[0073] In some embodiments, the waterproof heat dissipation structure further includes an end cover (not shown in the figure), and the box body and the end cover are buckled together to form an inner cavity for installing the circuit module 5. The end cover can be connected to the side of the box body 1 opposite to the first window 11.
[0074] The waterproof heat dissipation structure provided by the utility model effectively increases the heat dissipation capacity and improves the heat dissipation efficiency of the circuit module 5 by arranging the first window 11, the second window 13 and the radiator 4 on the box body 1; by arranging the first louver 2 and the first waterproof platform 12 on the first window 11, and arranging the second louver 3 and the second waterproof platform 14 on the second window 13, the first window 11 and the second window 13 are waterproofed, thereby extending the service life of the circuit module 5, reducing the failure rate of the product, and ensuring the use quality of the product.

A first window 11 for heat dissipation can be set on the side wall of the box body 1, and the first louver 2 is set in the first window 11 to waterproof the first window 11.
[0077] The edge of the first window 11 is surrounded by a first waterproof platform 12, which plays a waterproof role on the edges around the first window 11. The first waterproof platform 12 forms a first drainage slope 121 at the bottom edge of the first window 11, and the first drainage slope 121 slopes downward from the inside to the outside to guide water drops to flow outside the box body 1.
[0078] In some embodiments, a second window 13 may be further provided on the box body 1 to further increase the heat dissipation efficiency of the circuit module 5. A second shutter 3 is provided in the second window 13 to provide waterproofing for the second window 13.
