Description

Technical Field

[0001] This utility model relates to resistor housings, and more specifically to a heat dissipation window for resistor housings. Background Technology

[0002] Resistors are widely used in various electrical equipment in modern industry. Their working stability affects the stability of electrical equipment, so resistors need to be able to operate safely, continuously and stably under various complex working conditions.

[0003] As the energy and power requirements of electrical equipment in modern industry increase, the number of resistor modules that need to be installed in the resistor box also increases. When the resistor is working, it will generate a lot of heat. If the excessive heat cannot be dissipated through air convection or thermal radiation, the thermal equilibrium temperature inside the resistor box will exceed the design temperature. This will directly affect the resistance stability of the resistor module material and seriously affect the normal operation of the resistor.

[0004] On the other hand, with the widespread adoption of resistors in industrial production, their application scenarios have expanded to include outdoor environments. In such scenarios, the protection of the resistor enclosure faces more stringent challenges. To dissipate heat, resistor enclosures typically have ventilation windows on their outer walls. However, most of these ventilation windows are designed for indoor environments, focusing only on ventilation performance without considering the impact of external rain, dust, and other factors in outdoor environments. When used outdoors, dust can easily accumulate in the air ducts of the ventilation windows, reducing the flow area and affecting heat dissipation. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the existing heat dissipation window design of resistor housing does not take into account the open environment, and that sand and dust easily accumulate in the air duct of the heat dissipation window, resulting in a reduction in the flow area and affecting heat dissipation. Therefore, this invention provides a heat dissipation window for resistor housing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat dissipation window for a resistor housing, characterized by including a window frame and multiple S-shaped louvers;

[0008] The multiple S-shaped louvers are arranged sequentially from top to bottom inside the window frame, and the two ends of the S-shaped louvers are respectively connected to the two ends of the window frame.

[0009] The S-shaped louver includes a guide plate and a first vertical section, an inclined section, and a second vertical section connected in sequence. The first vertical section is located at the top of the second vertical section, and the first vertical section is located on the inner side, while the second vertical section is located on the outer side. The inclined section is connected to one end of the first vertical section and the second vertical section, respectively. Furthermore, for two adjacent S-shaped louvers, the second vertical section of the upper S-shaped louver coincides with the projection of the first vertical end of the lower S-shaped louver in the plane where the first vertical section or the second vertical section is located.

[0010] The guide plate includes a first guide plate disposed at the other end of the first vertical section and a second guide plate disposed at the other end of the second vertical section, wherein the first guide plate is bent toward the plane of the second vertical section and the second guide plate is bent toward the plane of the first vertical section.

[0011] The angle between the first guide vane and the first vertical section is 100°-170°, and the angle between the second guide vane and the second vertical section is 100°-170°.

[0012] Furthermore, the angle between the first guide vane and the first vertical section is 120°-140°; the angle between the second guide vane and the second vertical section is 120°-140°.

[0013] Furthermore, the angle between the first guide vane and the first vertical section is 130°; the angle between the second guide vane and the second vertical section is 130°.

[0014] Furthermore, the window frame is a rectangular frame structure, including a left frame, a top frame, a right frame, and a bottom frame connected in sequence, and the two ends of the S-shaped louver are connected to the left frame and the right frame, respectively.

[0015] Furthermore, it also includes outer reinforcing ribs, which are arranged vertically and connected to the upper frame, the second vertical section of the plurality of S-shaped louvers, and the lower frame, respectively.

[0016] Furthermore, it also includes inner reinforcing ribs, which are arranged vertically and connected to the upper frame, the first vertical segment of the plurality of S-shaped louvers, and the lower frame, respectively.

[0017] Furthermore, the two ends of the S-shaped louver are connected to the left frame and the right frame respectively by rivets;

[0018] The outer reinforcing ribs are connected to the upper frame, the second vertical section of the multiple S-shaped louvers, and the lower frame by rivets.

[0019] The inner reinforcing ribs are connected to the upper frame, the first vertical section of the multiple S-shaped louvers, and the lower frame by rivets.

[0020] Furthermore, a screen is provided on the inner side of the window frame, and the four sides of the screen are connected to the left frame, the top frame, the right frame and the bottom frame respectively.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) The heat dissipation window for a resistor housing provided by this utility model includes a window frame and a plurality of S-shaped louvers arranged sequentially from top to bottom within the window frame. For two adjacent S-shaped louvers, the second vertical section of the top S-shaped louver and the first vertical end of the bottom S-shaped louver are projected onto the plane of either the first or second vertical section. This prevents external dust, rain, and snow from blowing directly into the resistor housing, allowing the heat dissipation window to still provide normal heat dissipation and ventilation. A first guide plate is provided at the other end of the first vertical section, and a guide plate is provided at the other end of the second vertical section. The second guide plate is responsible for guiding the hot air inside the box to the outside. Due to the arrangement of the two adjacent S-shaped louvers, and if sand and dust from the outside want to enter the resistor box, the sand and dust need to move upward against gravity, and the two guide plates will also block it. At this time, some sand and dust will fall on the second guide plate. If too much sand and dust accumulates, it will affect the flow. Therefore, the angle between the first guide plate and the first vertical section is 100°-170°, and the angle between the second guide plate and the second vertical section is 100°-170°. Because of the angle, sand and dust cannot accumulate in large quantities, ensuring smooth flow.

[0023] (2) The heat dissipation window frame for resistor housing provided by this utility model adopts a split structure, including a left frame, a top frame, a right frame and a bottom frame connected in sequence. This allows for the use of different sized window frames according to the heat dissipation requirements of different resistor housings, thereby improving the applicability of the heat dissipation window.

[0024] (3) The two ends of the S-shaped louvered strip in the heat dissipation window of the resistor box provided by this utility model are respectively connected to the left side frame and the right side frame by rivets; the outer reinforcing ribs are respectively connected to the upper side frame, the second vertical section of the multiple S-shaped louvered strips and the lower side frame by rivets; the inner reinforcing ribs are respectively connected to the upper side frame, the first vertical section of the multiple S-shaped louvered strips and the lower side frame by rivets. Since the resistor box is mostly used outdoors, if bolts are used for connection, external vibrations can easily cause the bolts to loosen. Using rivets for connection is more stable.

[0025] (4) The heat dissipation window for resistor housing provided by this utility model has a mesh screen on the inner side of the window frame, which can prevent flying insects from entering the resistor housing through the heat dissipation window and ensure the normal operation of the resistor.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1-3 The present invention provides a heat dissipation window for a resistor housing, comprising a window frame 1 and multiple S-shaped louvers 2. The window frame 1 is a rectangular frame structure, including a left side frame 11, a top side frame 12, a right side frame 13 and a bottom side frame 14 connected in sequence. Multiple S-shaped louvers 2 are arranged in sequence from top to bottom inside the window frame 1, and the two ends of the S-shaped louvers 2 are respectively connected to the left side frame 11 and the right side frame 13 at both ends of the window frame 1.

[0033] The structure of S-shaped louver 2 is as follows: Figure 3 As shown, the device includes a guide plate and a first vertical section 21, an inclined section 22, and a second vertical section 23 connected in sequence. The first vertical section 21 is located at the top of the second vertical section 23 and is situated inside the window frame 1, which is the interior of the resistor housing. The second vertical section 23 is located outside the window frame 1, which is the exterior of the resistor housing. The inclined section 22 is connected to one end of both the first vertical section 21 and the second vertical section 23.

[0034] The deflector includes a first deflector 24 disposed at the other end of the first vertical section 21 and a second deflector 25 disposed at the other end of the second vertical section 23, wherein the first deflector 24 is bent toward the plane of the second vertical section 23 and the second deflector 25 is bent toward the plane of the first vertical section 21.

[0035] When arranging multiple S-shaped louvers 2, for two adjacent S-shaped louvers 2, the second vertical segment 23 of the upper S-shaped louver 2 and the first vertical end 21 of the lower S-shaped louver 2 have their projections in the plane where the first vertical segment 21 or the second vertical segment 23 is located coincide. This prevents sand or snow 5 blowing towards the heat dissipation window from directly entering the resistor box, and the heat dissipation window can still provide normal heat dissipation and ventilation. The hot air flow direction 6 is as follows: Figure 3 As shown, the two baffles are responsible for directing the hot air inside the resistor housing to the outside of the resistor housing.

[0036] If external dust wants to enter the resistor housing, it needs to move upward against gravity. At this time, the two guide plates will block it. Some of the dust will fall on the second guide plate 25. If too much dust accumulates, it will affect the current flow. Therefore, the angle between the first guide plate 24 and the first vertical section 21 is 100°-170°, and the angle between the second guide plate 25 and the second vertical section 23 is 100°-170°. Because of the angle, the dust will slide off the second guide plate 25 and cannot accumulate in large quantities, ensuring smooth current flow. If the angle is less than 100°, the dust cannot slide off on its own and will still accumulate in large quantities. Especially if the angle is 90 degrees, although it is convenient for processing, the dust will easily accumulate and affect the current flow.

[0037] In this embodiment, the angle between the first guide plate 24 and the first vertical section 21 is generally 120°-140°; the angle between the second guide plate 25 and the second vertical section 23 is 120°-140°. Preferably, the angle between the first guide plate 24 and the first vertical section 21 is 130°, and the angle between the second guide plate 25 and the second vertical section 23 is 130°, because the angle processing is convenient, the forming effect is good, and it is easy to stamp and form.

[0038] If the S-shaped louver 2 is very long, the structural strength of the entire heat dissipation window will be weakened. Therefore, an outer reinforcing rib 3 is also provided on the outside of the window frame 1, and its structure is as follows: Figure 1 As shown, an inner reinforcing rib 4 is provided on the inner side of the window frame 1, and its structure is as follows. Figure 2 As shown. The outer reinforcing rib 3 is arranged vertically and is connected to the upper frame 12, the second vertical section 23 of the multiple S-shaped louvers 2 and the lower frame 14 respectively; the inner reinforcing rib 4 is arranged vertically and is connected to the upper frame 12, the first vertical section 21 of the multiple S-shaped louvers 2 and the lower frame 14 respectively.

[0039] Because the heat dissipation windows in this embodiment are mostly used in outdoor environments, and in situations where the resistor box vibrates due to wind, if the components are connected by bolts, the vibration will cause the bolts to loosen, which will pose a certain safety hazard in the long run. Therefore, in this embodiment, the two ends of the S-shaped louver 2 are connected to the left frame 11 and the right frame 13 by rivets, respectively. The outer reinforcing rib 3 is connected to the upper frame 12, the second vertical sections 23 of the multiple S-shaped louver 2, and the lower frame 14 by rivets, respectively. The inner reinforcing rib 4 is connected to the upper frame 12, the first vertical sections 21 of the multiple S-shaped louver 2, and the lower frame 14 by rivets, respectively. Riveting can resist vibration and make the connection more stable.

[0040] When used in outdoor environments, in addition to the influence of weather factors such as sandstorms, rain and snow, flying insects may also crawl into the resistor box through the heat dissipation window, which may cause short circuits. Therefore, a mesh screen is installed inside the window frame 1, and the four sides of the mesh screen are connected to the left frame 11, the top frame 12, the right frame 13 and the bottom frame 14 respectively.

[0041] During use, hot air flows from inside the resistor housing to the outside, and the hot air flows in the direction of 6. Figure 3 As shown, the first guide plate 24 and the second guide plate 25 are used to provide guidance and improve heat dissipation efficiency. If external sand and dust want to enter the resistor box, they need to move upward against gravity. At this time, the two guide plates will block them. Some of the sand and dust will fall on the second guide plate 25. Because of the angle between the second guide plate 25 and the second vertical part 23, the sand and dust will slide off the second guide plate 25 and will not accumulate, thus not affecting the current flow.

[0042] The embodiments described above are merely descriptions of specific implementations of this utility model and are not intended to limit the scope of this utility model. Various modifications and improvements made to the technical solutions of this utility model by those skilled in the art without departing from the spirit of this utility model should fall within the protection scope defined by the claims of this utility model.
