Description

Technical Field

[0001] This utility model relates to the field of combiner technology, and in particular to a heat dissipation structure and a bridge combiner. Background Technology

[0002] A bridge combiner is a circuit element that combines the characteristics of a bridge and a combiner. It can be used to measure physical quantities such as resistance and capacitance (the function of a bridge), and it can also realize the synthesis and control of multiple signals (the function of a combiner). In communication systems, bridge combiners are widely used in signal transmission and conversion, especially in the fields of radio communication and mobile communication.

[0003] In the prior art, such as Chinese Patent No. CN210928459U, there is a heat dissipation structure and a bridge combiner. The heat dissipation structure includes a cover plate, a PCB board, and at least one combining device. At least one device receiving groove is provided on one end face of the cover plate opposite to the PCB board. The combining device is partially or completely accommodated in the device receiving groove. The PCB board has traces, and the combining device is electrically connected to the traces. This utility model improves the heat dissipation efficiency without increasing the overall size and cost of the combiner.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: Although it can improve the heat dissipation efficiency and reduce the temperature rise by setting a device receiving slot on the cover plate to accommodate the key components of the combiner closer to the bottom surface of the cover plate, thus changing the non-contact air convection heat dissipation of the components to direct contact heat conduction to the cover plate, it still relies on natural heat dissipation through heat dissipation fins, which has relatively low heat dissipation efficiency. When the bridge combiner is used in a high-temperature environment and the gas flow speed is slow, the heat dissipation effect of the bridge combiner is poor. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that, although it can improve the heat dissipation efficiency and reduce the temperature rise by setting a device receiving groove on the cover plate to accommodate the key components of the combiner closer to the bottom surface of the cover plate, and improve the non-contact air convection heat dissipation of the components to the cover plate by direct contact heat conduction, it still has a low heat dissipation efficiency due to the natural heat dissipation method of heat dissipation teeth. When the bridge combiner is used in a high-temperature environment and the gas flow speed is slow, the heat dissipation effect of the bridge combiner is poor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat dissipation structure for an electric bridge combiner, comprising: two square frames, a heat dissipation pipe fixedly connected to one side of the square frames, a bracket fixedly connected to the inner wall of the heat dissipation pipe, a rotating rod rotatably connected to the center of the bracket, a fan blade fixedly connected to one end of the rotating rod, a motor fixedly connected to one side of the bracket, and the output end of the motor fixedly connected to the other end of the rotating rod.

[0007] Preferably, a flow guide plate is provided inside the frame near the heat dissipation pipe, and multiple flow guide holes are equally spaced on the outer surface of the flow guide plate, and the flow guide plate is configured in a V-shape.

[0008] Preferably, the top of the frame is fixedly connected with a plurality of heat dissipation fins three in pairs symmetrically and at equal intervals, the bottom of each heat dissipation fin three is set to be inclined, and the bottom of each heat dissipation fin three extends into the interior of the frame.

[0009] Preferably, a dustproof net one is fixedly connected to one side of the frame, a guide plate is fixedly connected to one side of the dustproof net one, a dustproof net two is fixedly connected to the side of the frame away from the heat dissipation pipe, and a dustproof net three is fixedly connected to the inner wall of the heat dissipation pipe away from the frame.

[0010] A bridge combiner includes: a bridge combiner housing, wherein heat dissipation grooves are provided on opposite sides of the bridge combiner housing, the outer surface of a frame is fixedly connected to the inner wall of the heat dissipation grooves, and a plurality of heat dissipation fins are fixedly connected at equal intervals on one side of the inner wall of the heat dissipation grooves, the heat dissipation fins being disposed inside the frame.

[0011] Preferably, a second heat dissipation groove is formed at the top of the inner wall of the first heat dissipation groove, and the third heat dissipation fin is disposed inside the second heat dissipation groove.

[0012] Preferably, the top of the bridge combiner housing is fixedly connected with multiple heat dissipation fins at equal intervals.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model controls the motor to start via a controller, causing its output shaft to drive the rotating rod to rotate, which in turn drives the fan blades to rotate, blowing air into the interior of the frame. With the help of the guide plate, the air is directed to the top and bottom of the frame, and with the tilting of the bottom of the third heat dissipation fin, the air is directed between two adjacent second heat dissipation fins to dissipate heat. At the same time, the air can pass through the guide hole to dissipate heat from the first second heat dissipation fin. The third heat dissipation fin can absorb heat from inside the frame and transfer it to the outside of the frame. With the help of the air blowing, the heat dissipation fin is cooled down, and the hot air is discharged outward through the first and second dustproof nets. In this way, when the bridge combiner housing is used in a high-temperature environment, the heat dissipation of the second heat dissipation fin can be accelerated by increasing the air flow speed, thereby improving the heat dissipation effect of the bridge combiner housing.

[0015] 2. This utility model, through the arrangement of heat dissipation fin one and heat dissipation fin two, can transfer the heat inside the bridge combiner housing, thereby reducing the temperature inside the bridge combiner housing. By setting two sets of heat dissipation fin two on the side of the bridge combiner housing, the heat dissipation effect of the bridge combiner housing can be further improved. While ensuring the heat dissipation effect of the bridge combiner housing, the height of heat dissipation fin one is reduced. This not only improves the heat dissipation effect of the bridge combiner housing, but also reduces the overall height of the bridge combiner housing. Attached Figure Description

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, such as Figure 1-4 As shown, this utility model provides a heat dissipation structure for an electric bridge combiner, including: two square frames 2, a heat dissipation pipe 3 fixedly connected to one side of the square frame 2, a bracket 302 fixedly connected to the inner wall of the heat dissipation pipe 3, a rotating rod 303 rotatably connected to the center of the bracket 302, a fan blade 304 fixedly connected to one end of the rotating rod 303, a motor 305 fixedly connected to one side of the bracket 302, and the output end of the motor 305 fixedly connected to the other end of the rotating rod 303.

[0025] Furthermore, such as Figure 1-4 As shown, a guide plate 203 is provided inside the frame 2 near the heat pipe 3. Multiple guide holes 204 are equidistantly opened on the outer surface of the guide plate 203. The guide plate 203 is set in a V shape. Through the setting of the guide plate 203, the air can be guided to the top and bottom of the frame 2. Then, through the setting of the guide holes 204, the air can be blown onto the first heat dissipation fin 104 to dissipate heat.

[0026] Furthermore, such as Figure 1-4 As shown, multiple heat dissipation fins 205 are symmetrically and equidistantly fixed to the top of the frame 2. The bottom of each heat dissipation fin 205 is set to be inclined and extends into the interior of the frame 2. The heat dissipation fins 205 achieve a certain heat dissipation effect. The inclined bottom of the heat dissipation fins 205 can guide the air towards the middle of two adjacent heat dissipation fins 204, so that the heat dissipation fins 204 can blow air all over the frame.

[0027] Furthermore, such as Figure 1-4As shown, a dustproof net 201 is fixedly connected to one side of the frame 2, and a baffle plate 203 is fixedly connected to one side of the dustproof net 201. A dustproof net 202 is fixedly connected to the side of the frame 2 away from the heat dissipation pipe 3. A dustproof net 301 is fixedly connected to the heat dissipation pipe 3 away from the inner wall of the frame 2. The dustproof net 201, dustproof net 202 and dustproof net 301 are set to achieve a certain dustproof effect and allow the airflow inside the frame 2 to circulate and dissipate heat.

[0028] A bridge combiner includes: a bridge combiner housing 1, with heat dissipation grooves 102 on both opposite sides of the bridge combiner housing 1, the outer surface of a frame 2 being fixedly connected to the inner wall of the heat dissipation grooves 102, and a plurality of heat dissipation fins 104 being fixedly connected at equal intervals on one side of the inner wall of the heat dissipation grooves 102, the heat dissipation fins 104 being disposed inside the frame 2.

[0029] Furthermore, such as Figure 1-4 As shown, a second heat dissipation groove 103 is provided on the top of the inner wall of the first heat dissipation groove 102, and a third heat dissipation fin 205 is disposed inside the second heat dissipation groove 103. The arrangement of the second heat dissipation groove 103 facilitates the contact between the third heat dissipation fin 205 and the outside environment, thereby improving the heat dissipation effect of the third heat dissipation fin 205.

[0030] Furthermore, such as Figure 1-4 As shown, multiple heat dissipation fins 101 are fixedly connected at equal intervals on the top of the bridge combiner housing 1. The heat dissipation fins 101 provide a certain heat dissipation effect.

[0031] Working Principle: During use, the heat dissipation fins 101 and 104 transfer heat from the inside of the bridge combiner housing 1, thereby reducing the internal temperature of the bridge combiner housing 1. By installing two sets of heat dissipation fins 104 on the side of the bridge combiner housing 1, the heat dissipation effect of the bridge combiner housing 1 can be further improved. While ensuring the heat dissipation effect of the bridge combiner housing 1, the height of the heat dissipation fins 101 is reduced. This not only improves the heat dissipation effect of the bridge combiner housing 1 but also reduces the overall height of the bridge combiner housing 1. The controller then starts the motor 305, causing its output shaft to drive the rotating rod 303 to rotate, simultaneously driving the fan blades 304 to rotate, blowing air into the inside of the frame 2. With the assistance of the guide plate 203, the air is directed to the top and bottom of the frame 2, and the heat dissipation is achieved. With the bottom of fin 205 tilted, air is guided between the two adjacent heat dissipation fins 104 to dissipate heat. At the same time, air can pass through the guide hole 204 to dissipate heat from the first heat dissipation fin 104. Heat dissipation fin 205 can absorb heat inside the frame 2 and transfer it to the outside of the frame 2. With the help of airflow, heat dissipation fin 205 dissipates heat, and hot air is discharged outward through dustproof net 1 201 and dustproof net 2 202. In this way, when the bridge combiner housing 1 is used in a high-temperature environment, the heat dissipation of heat dissipation fin 104 can be accelerated by increasing the airflow speed, thereby improving the heat dissipation effect of the bridge combiner housing 1. With the cooperation of dustproof net 1 201, dustproof net 202 and dustproof net 301, a certain dustproof effect is achieved.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
