Description

Technical Field

[0001] The present application relates to the technical field of resistors, and more particularly to a resistor with an aluminum housing for heat dissipation. Background Art

[0002] Aluminum-cased resistors, with their housings made of aluminum alloy (golden aluminum), feature heat dissipation grooves on the surface. They offer high power, high temperature resistance, strong overload capacity, and weather resistance, along with high precision, standard low-inductance resistance, high stability, and a robust structure. They offer excellent flexibility, multiple combination options, mechanical protection, and ease of installation and use. Like other resistors, aluminum-cased resistors, in physics, represent the degree of resistance a conductor offers to current flow. The greater the resistance, the greater the resistance. Different conductors generally have different resistances. Resistance is a characteristic of the conductor itself, and it affects the amount of electron flow. Lower resistance means higher electron flow, and vice versa.

[0003] In actual use, some existing resistors form an insulating part between the resistor body and the shell, which makes it difficult for the heat inside the resistor to be dissipated by the aluminum shell alone. As a result, most of the heat remains inside, making it difficult to use the resistor at full load for a long time.

[0004] In order to solve the above problems, the present application provides a resistor with an aluminum housing for heat dissipation. Utility Model Content

[0005] The present application provides a resistor with an aluminum housing for heat dissipation, which adopts the following technical solution:

[0007] Furthermore, the heat dissipation assembly includes a threaded rod, a fixed rod, a movable block, a connecting plate, a connecting shaft and a top plate. The threaded rod is arranged on the top of the shell, and one end of the threaded rod extends to one side of the shell and is fixedly connected to a knob.

[0008] Through the above technical solution, through the mutual cooperation between the internal structures of the heat dissipation components, the fan plates on the front and back sides of the shell can be driven to rotate and open, allowing the internal and external air to interact, thereby facilitating the dissipation of heat when the resistor body is working.

[0009] Furthermore, the bottom end of the moving block is slidably connected to the top inner wall of the shell, a threaded hole adapted to the threaded rod is provided inside the moving block, and the moving block is sleeved on the outside of the threaded rod.

[0010] Through the above technical solution, when the threaded rod rotates clockwise and counterclockwise, the moving block can move back and forth on the top of the shell.

[0011] Furthermore, the plurality of connecting plates are symmetrically arranged on the front and back sides of the moving block, the plurality of fixing rods are evenly arranged between the plurality of connecting plates, and the opposite ends of two connecting plates are symmetrically arranged on the front and back sides of the moving block.

[0012] Through the above technical solution, multiple connecting plates are connected into a whole through the fixing rods. When one of them moves, the whole can be driven to move synchronously.

[0013] Furthermore, a sliding groove adapted to the connecting shaft is provided inside the connecting plate, the connecting shaft is slidably connected inside the sliding groove, and the top end of the connecting shaft is fixedly connected to the bottom end of the top plate.

[0014] Through the above technical solution, when the connecting plate moves, the connecting shaft can be driven to move, and at the same time the connecting shaft can be caused to slide inside the connecting plate.

[0015] Furthermore, a circular hole adapted to the rotating rod is opened at one end of the top plate, and one end of the rotating rod extends to the top of the shell and is fixedly sleeved inside one end of the top plate.

[0016] Through the above technical solution, when the top plate rotates, it can drive the rotating rod to rotate, thereby driving the fan plate to rotate.

[0017] In summary, this application has the following beneficial technical effects:

[0018] This utility model designs a heat dissipation component. Through the mutual cooperation between the internal structures of the component, the fan plates on the front and back sides of the shell can be driven to rotate and open, allowing the air inside and outside to interact, thereby facilitating the dissipation of heat when the resistor body is working, improving the heat dissipation effect, and ensuring the normal use of the equipment.

[0028] Example:

[0029] The present application discloses a resistor with an aluminum housing for heat dissipation. Figure 1 、 Figure 2 、 Figure 3 and Figure 4, including a shell 2, a cavity is opened inside the shell 2, a resistor body 1 is arranged inside the cavity, a base 3 is provided at the bottom end of the shell 2, slots are symmetrically opened on the front and back sides of the shell 2, fan plates 4 are evenly arranged inside the slots, and when multiple fan plates 4 are rotated, tilted and overlapped, the shell 2 can be closed, a rotating rod 5 is provided inside the fan plate 4, and both ends of the rotating rod 5 are rotatably connected inside the slot, and a heat dissipation component is provided on the top of the shell 2.

[0030] See also Figure 2 、 Figure 3 and Figure 4 The heat dissipation assembly includes a threaded rod 7, a fixed rod 8, a moving block 9, a connecting plate 10, a connecting shaft 11 and a top plate 12. The threaded rod 7 is arranged on the top of the shell 2, and one end of the threaded rod 7 extends to one side of the shell 2 and is fixedly connected to the knob 6.

[0031] Through the mutual cooperation between the internal structures of the heat dissipation components, the fan plates 4 on the front and back sides of the shell 2 can be driven to rotate and open, so that the inside and outside air can interact, thereby facilitating the heat dissipation when the resistor body 1 is working.

[0032] See also Figure 2 、 Figure 3 and Figure 4 The bottom end of the moving block 9 is slidably connected to the top inner wall of the shell 2. A threaded hole that matches the threaded rod 7 is opened inside the moving block 9, and the moving block 9 is sleeved on the outside of the threaded rod 7.

[0033] The other end of the threaded rod 7 is rotatably connected to the inner wall of one side of the top of the housing 2 . When the threaded rod 7 rotates clockwise or counterclockwise, the moving block 9 can move back and forth on the top of the housing 2 .

[0034] See also Figure 2 、 Figure 3 and Figure 4 , multiple connecting plates 10 are symmetrically arranged on the front and back sides of the moving block 9, and multiple fixing rods 8 are evenly arranged between the multiple connecting plates 10, wherein the opposite ends of two connecting plates 10 are symmetrically arranged on the front and back sides of the moving block 9.

[0035] The plurality of connecting plates 10 are connected into a whole through the fixing rod 8 , and when one of them moves, the whole can be driven to move synchronously.

[0036] See also Figure 2 、 Figure 3 and Figure 4 A chute adapted to the connecting shaft 11 is provided inside the connecting plate 10 , and the connecting shaft 11 is slidably connected inside the chute, and the top end of the connecting shaft 11 is fixedly connected to the bottom end of the top plate 12 .

[0039] The top end of the top plate 12 is slidably connected to the top inner wall of the housing 2. When the top plate 12 rotates, it can drive the rotating rod 5 to rotate, thereby driving the fan plate 4 to rotate.

[0040] The implementation principle of this embodiment is as follows: when working, rotating the knob 6 clockwise can drive the threaded rod 7 to rotate. Since a threaded hole that is compatible with the threaded rod 7 is opened inside the moving block 9, when the threaded rod 7 rotates, it can drive the moving block 9 to move to the side away from the knob 6, and then through the mutual cooperation of two connecting plates 10 and multiple fixed rods 8, the entire connecting plate 10 is driven to move synchronously. When the connecting plate 10 moves, it can drive the internal connecting shaft 11 to move, and then the top plate 12 at the top is driven to rotate through the connecting shaft 11, and then the fan plate 4 is driven to rotate through the rotating rod 5, thereby opening, thereby facilitating internal heat dissipation.
