Description

Technical Field

[0001] This utility model relates to the field of aluminum housing technology, specifically to an attenuator fixed aluminum housing with a heat dissipation structure. Background Technology

[0002] An attenuator is an electronic component used to reduce signal strength. It is widely used in communications, radar, testing and measurement, and other fields. Its core function is to reduce the electrical signal power in the transmission line in a controllable way, so as to avoid equipment damage or measurement distortion caused by excessive signal strength. To ensure its performance, fixed attenuators are usually encapsulated in a metal shell. For example, the patent with publication number CN207116649U (an attenuator) includes: a transmission rod with a cavity inside; an input port and an output port connected to both sides of the transmission rod; an attenuator plate disposed in the cavity, with both sides of the attenuator plate engaging with grooves in the cavity, and thermally conductive adhesive coated between the grooves and the attenuator plate; pins connecting the attenuator plate to the input port and the output port respectively; and multiple sets of heat sinks disposed on the transmission rod. Although the existing technology uses thermally conductive silicone pads for sealing, making it waterproof and dustproof, it relies on passive heat dissipation. As the power increases or the attenuator operates for extended periods, the heat generated by the internal components is difficult to dissipate quickly and efficiently, which can lead to excessively high local temperatures and affect the stability of the attenuator's performance. Therefore, there is an urgent market need to develop an attenuator with a heat dissipation structure and a fixed aluminum housing to help solve the existing problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an attenuator with a heat dissipation structure is fixed to an aluminum housing, including a mounting cylinder. A heat dissipation shell is fixedly installed on the outer side of the mounting cylinder. Fan cylinders are symmetrically fixedly installed on both sides of the rear end of the heat dissipation shell. The fan cylinders are connected to the heat dissipation shell. A fan is fixedly installed inside the fan cylinder. A dust filter plate is fixedly installed at the rear end inside the fan cylinder. Multiple air holes are provided on both the upper and lower surfaces of the heat dissipation shell.

[0005] Preferably, a plurality of heat sinks are fixedly installed on the outer side of the mounting cylinder. The plurality of heat sinks are arranged at intervals along the axial direction of the mounting cylinder. The upper end of the heat sink extends to the top of the heat sink housing, and the lower end of the heat sink extends to the bottom of the heat sink housing. The air hole is located between two adjacent heat sinks.

[0006] Preferably, the mounting cylinder, heat sink housing, and heat sink are all made of die-cast aluminum alloy.

[0007] Preferably, the heat sink has multiple heat dissipation grooves on both sides of its upper and lower ends, and the interior of the heat dissipation grooves is coated with a graphene coating.

[0008] Preferably, the outer side of the mounting cylinder is provided with multiple strip-shaped slots, and the multiple strip-shaped slots are arranged in a ring.

[0009] Preferably, a second dust filter plate is fixedly installed inside the air hole, and the second dust filter plate is fixedly connected to the heat dissipation shell.

[0010] Preferably, upright plates are symmetrically fixedly installed on the lower sides of the heat dissipation housing, and mounting strips are fixedly installed on the lower sides of the upright plates. The mounting strips have multiple bolt holes arranged at intervals.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model constructs an efficient active heat dissipation air duct by using the heat dissipation shell on the outside of the mounting cylinder and the symmetrically arranged fan cylinder, along with multiple air holes on the upper and lower end faces of the shell. During the high power or long-term operation of the attenuator, the heat generated by the internal components can be conducted by the shell and quickly discharged to the outside by means of the combination of fan and air hole ventilation, effectively avoiding the problem of excessive local temperature, improving heat dissipation efficiency, and contributing to the stability and reliability of the attenuator.

[0012] (2) By setting multiple heat sinks, and extending the upper and lower ends of the heat sinks to the upper and lower parts of the heat sink housing, the heat dissipation area is increased, which can make more extensive contact with the surrounding air, accelerate the dissipation of heat, and when the air flows through the air holes, it can drive the flow of the air around the heat sink, further improving the heat dissipation effect.

[0013] (3) By setting multiple heat dissipation grooves and setting a graphene coating inside them, this utility model not only increases the surface area of ​​the heat sink, but also the graphene has a very high thermal conductivity, which can quickly conduct the heat on the heat sink, accelerate the heat dissipation speed, and improve the heat dissipation performance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1-4 An embodiment of this utility model provides: an attenuator with a heat dissipation structure is fixed to an aluminum shell, including a mounting cylinder 1, a heat dissipation shell 2 is fixedly installed on the outside of the mounting cylinder 1, a fan cylinder 6 is symmetrically fixedly installed on both sides of the rear end of the heat dissipation shell 2, the fan cylinder 6 is connected to the heat dissipation shell 2, a fan is fixedly installed inside the fan cylinder 6, a dust filter plate 7 is fixedly installed at the rear end inside the fan cylinder 6, and multiple air holes 201 are provided on the upper and lower surfaces of the heat dissipation shell 2.

[0017] The fan inside the fan casing 6, along with the air vent 201, can accelerate airflow and form an effective heat dissipation channel, quickly carrying away internal heat. Furthermore, the dust filter plate 7 installed inside the fan casing 6 can prevent dust from entering the interior and affecting the performance of the components while ensuring airflow. This achieves efficient and rapid dissipation of the heat generated by the internal components of the attenuator, increasing the stability of the attenuator's performance.

[0018] Please see Figure 3 Multiple heat sinks 5 are fixedly installed on the outside of the mounting cylinder 1. The multiple heat sinks 5 are arranged at intervals along the axial direction of the mounting cylinder 1. The upper end of the heat sink 5 extends to the top of the heat sink housing 2, and the lower end of the heat sink 5 extends to the bottom of the heat sink housing 2. The air hole 201 is located between two adjacent heat sinks 5.

[0019] Multiple heat sinks 5 increase the heat dissipation area, and the upper and lower ends of the heat sinks 5 extend to the upper and lower parts of the heat dissipation shell 2, which can have a wider contact with the surrounding air and accelerate the dissipation of heat. The air holes 201 are located between two adjacent heat sinks 5, so that when the air flows through the air holes 201, it can have a more thorough heat exchange with the heat sinks 5, further improving the heat dissipation effect.

[0020] Please see Figure 1 The mounting cylinder 1, the heat dissipation shell 2, and the heat dissipation fins 5 are all made of die-cast aluminum alloy.

[0021] Aluminum alloy has good thermal conductivity, which can quickly conduct the heat generated by the components inside the mounting cylinder 1 to the heat dissipation shell 2 and heat sink 5, accelerating the heat dissipation process and increasing practicality.

[0022] Please see Figure 1 Multiple heat dissipation grooves 501 are provided on both sides of the upper and lower ends of the heat sink 5, and the interior of the heat dissipation grooves 501 is coated with graphene.

[0023] The multiple heat dissipation grooves 501 provided on the heat sink 5 further increase the surface area of ​​the heat sink 5 and improve the heat dissipation efficiency. In addition, the graphene coating provided has a very high thermal conductivity, which can quickly conduct the heat on the heat sink 5 away, accelerate the heat dissipation speed, improve the heat dissipation performance, and help the attenuator work stably.

[0024] Please see Figure 4 The outer side of the mounting cylinder 1 is provided with multiple strip-shaped slots 101, and the multiple strip-shaped slots 101 are arranged in a ring.

[0025] The design of the strip-shaped slot 101 facilitates the dissipation of heat from the attenuator, effectively improving the heat dissipation capacity of the mounting cylinder 1 and increasing the stability of the attenuator operation.

[0026] Please see Figure 4 A dust filter plate 201 is fixedly installed inside the vent 201, and the dust filter plate 28 is fixedly connected to the heat dissipation shell 2.

[0027] The dust filter plate 28 effectively intercepts dust and debris as air enters and exits the heat dissipation housing 2 through the air vent 201, preventing them from entering and contaminating the internal components and affecting the heat dissipation effect, thus increasing its practicality.

[0028] Please see Figure 1 On the lower sides of the heat dissipation housing 2, upright plates 3 are symmetrically fixedly installed. On the lower side of the upright plates 3, mounting strips 4 are fixedly installed. Multiple bolt holes are provided inside the mounting strips 4, and the multiple bolt holes are arranged at intervals.

[0029] The installation of the upright plate 3 and the mounting strip 4 provides a stable mounting structure for fixing the aluminum housing of the attenuator. The multiple bolt holes spaced apart on the mounting strip 4 facilitate connection and fixation with external equipment or brackets, increasing practicality.

[0030] Working principle: During use, the attenuator is installed inside the mounting cylinder 1. The heat generated by the attenuator is first absorbed by the mounting cylinder 1 through heat conduction and then quickly conducted to the heat dissipation shell 2 and the arranged heat sink 5 that are fixedly connected to it. At the same time, the fan in the fan cylinder 6 starts to work, accelerating the air flow. Together with the multiple air holes 201 on the upper and lower end faces of the heat dissipation shell 2, an effective heat dissipation air channel is formed, which quickly carries away the internal heat. When the airflow flows through the heat sink 5, which is provided with heat dissipation grooves 501 and coated with ultra-high thermal conductivity graphene, it will exchange heat with the fins and carry away a large amount of heat. In addition, the strip-shaped slots 101 on the mounting cylinder 1 facilitate the internal airflow, which is conducive to the dissipation of the heat generated by the attenuator. During the entire heat dissipation process, the dust filter plate 7 and the dust filter plate 8 form a dust barrier, ensuring that while accelerating the air flow, dust is effectively blocked from entering, thereby achieving rapid and efficient heat dissipation and increasing the stability of the attenuator operation.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
