Description

Technical Field

[0001] The utility model relates to the technical field of down converters, in particular to a down converter. Background Art

[0002] Upconverter and downconverter are two common power conversion devices in power systems, which are usually used to adjust the frequency and voltage of AC power to meet the needs of different equipment or systems. The downconverter converts DC power into AC power, and generates AC output with adjustable frequency and voltage by inverting the DC signal. The downconverter usually consists of a set of switching devices and control circuits.

[0003] Downconverters are also used to convert intermediate frequency modulated signals into satellite communication downlink frequencies. For example, the existing public patent (publication number CN 209642646 U) discloses a high-quality four-output satellite downconverter, including a downconverter box, heat dissipation holes, a vibration-proof sponge surface, a front panel, an LED display, a test port, a frequency conversion indicator, a reserved port for downconverter installation, a satellite input interface, and a high-quality output interface. Two heat dissipation holes are arranged on the upper surface of the downconverter box, and the heat dissipation holes are directly opposite to the first converter and the first intermediate amplifier and equalizer in the downconverter box. A front panel is arranged in front of the downconverter box, an LED display is arranged at the center of the front panel, a test port is arranged at the left end of the LED display, and a frequency conversion indicator is arranged at the right end of the LED display. The height of the front panel is the same as that of the downconverter box, and the length of the front panel is longer than that of the downconverter box, which solves the problem that the output signal of the existing satellite downconverter is unstable and easily interfered by the outside world, and is suitable for promotion and use.

[0004] The above down converter has the same heat dissipation method as the common down converters in the current market, which is to dissipate heat through the openings in the shell, but the heat dissipation efficiency is low, and due to the lack of a protective structure, it is easy to accumulate a lot of dust, etc., which will affect the subsequent operation of the down converter in the long term. Therefore, the utility model proposes a down converter to improve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a down converter to solve the problems proposed in the above background technology that the existing down converter dissipates heat through openings in the shell, but the heat dissipation efficiency is low, and due to the lack of a protective structure, it is easy to accumulate a lot of dust, which will affect the subsequent operation of the down converter in the long term.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a down-converter, including a down-converter body; the down-converter body includes a shell, a control panel arranged on the front of the shell, an electronic screen embedded in the upper inclined surface of the shell, a partition net fitted on the heat dissipation port on the side of the shell, a bracket fixed to the back of the shell, a heat sink arranged inside the bracket, and a heat dissipation fan arranged at the bottom of the bracket.

[0007] Preferably, the control panel and the electronic screen are connected to internal components of a shell, and the internal components of the shell are connected to external components via wires.

[0008] Preferably, a wiring board is provided at the lower portion of the shell, and the shell wiring passes through a wiring board connection port, and the port is embedded in the lower portion of the shell.

[0009] Preferably, a limit strip is provided at the end of the partition net, and the limit strip is fixed to the side surface of the shell.

[0010] Preferably, the heat sinks are equidistantly and integrally arranged inside the bracket, and the heat sinks are located directly above the heat dissipation fan.

[0011] Preferably, the back opening of the shell matches the inner side of the bracket, and the inner end of the heat sink is located inside the shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model accelerates the overall heat dissipation of the down converter body by arranging an integral heat dissipation structure composed of a bracket, a heat sink and a heat dissipation fan, ensures the stable operation of the down converter body, avoids the influence of excessive internal temperature on the operation, and arranges a partition net to shield the heat dissipation port on the side of the shell. The gas exchanged with the inside of the shell is filtered by the partition net to absorb dust and moisture therein, and avoids the influence of dust and moisture mixed in the gas entering the inside of the shell on the internal components. The heat sink is located inside the shell to conduct the heat inside the shell. When the heat dissipation fan is started, the wind blown out passes through the gaps in the heat sink to take away the heat on the surface of the heat sink, thereby accelerating the heat conduction of the heat sink.

[0014] The wiring board provided at the same time is used to limit the positioning protection of the shell wiring. When wiring, the wiring is first passed through the round hole opened in the wiring board, and then connected to the inside of the port. This wiring method makes the wiring of the port clear and the wiring will not be tangled and disordered, which provides convenience for subsequent inspection and maintenance.

[0020] 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 implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0021] Example

[0022] See also Figure 1-4 , in the figure: This embodiment is a preferred implementation of the technical solution, a down converter, including a down converter body 1; the down converter body 1 includes a shell 11, a control panel 13 arranged on the front of the shell 11, an electronic screen 12 embedded in the upper inclined surface of the shell 11, a partition 15 fitted to the heat dissipation port on the side of the shell 11, a bracket 17 fixed to the back of the shell 11, a heat sink 18 arranged inside the bracket 17, and a heat dissipation fan 19 arranged at the bottom of the bracket 17;

[0023] It should be noted that: in the downconverter body 1 involved in the present application, an overall heat dissipation structure consisting of a bracket 17, a heat sink 18 and a heat dissipation fan 19 is provided to accelerate the overall heat dissipation of the downconverter body 1, ensure the stable operation of the downconverter body 1, and avoid the internal temperature being too high to affect the operation, and a partition net 15 is provided to cover the heat dissipation port on the side of the shell 11. The gas exchanged with the inside of the shell 11 is filtered by the partition net 15 to absorb dust and moisture therein, thereby avoiding the dust and moisture mixed in the gas entering the inside of the shell 11 to affect its internal components. Specifically, after the downconverter body 1 is connected to the line for operation, the heat dissipation fan 19 is started at a fixed time, and the wind blows through the gaps in the heat sink 18 to take away the heat on the surface of the heat sink 18, thereby accelerating the heat conduction of the heat sink 18.

[0024] Among them Figure 1 As shown, the control panel 13 and the electronic screen 12 are connected to the internal components of the housing 11, and the internal components of the housing 11 are connected to the external components via wires;

[0025] It should be noted that the control panel 13 is used to monitor the status changes of the components inside the housing 11 , and the working status of each component is fed back to the electronic screen 12 in real time.

[0026] Among them Figure 1-3 As shown, a limit strip 16 is provided at the end of the partition net 15 , and the limit strip 16 is fixed to the side surface of the shell 11 .

[0027] It should be noted that: the limit strip 16 is used to fix the position of the partition net 15, the inner groove of the limit strip 16 cooperates with the partition net 15, and there is a certain damping between the edge of the partition net 15 and the inner wall of the groove of the limit strip 16, so that the partition net 15 does not move relative to each other without external force. The loading and unloading of the partition net 15 relative to the limit strip 16 is also relatively simple, and the assembly and separation of the partition net 15 and the limit strip 16 can be completed by a push-pull method.

[0028] Among them Figure 1 and Figure 4 As shown, a wiring board 14 is disposed at the lower part of the housing 11, and the wiring of the housing 11 passes through the wiring board 14 to connect to the port 110, and the port 110 is embedded in the lower part of the housing 11;

[0029] It should be noted that the wiring board 14 provided at the lower part of the shell 11 is used to limit the positioning protection of the wiring of the shell 11. When wiring, the wiring is first passed through the round hole opened in the wiring board 14, and then connected to the inside of the port 110. This wiring method makes the wiring of the port 110 clear, and the wiring will not be tangled and disordered, which provides convenience for subsequent inspection and maintenance.

[0031] It should be noted that: the bracket 17 serves as the main frame of the heat dissipation structure, and the bracket 17 covers the opening on the back of the shell 11. After the bracket 17 and the shell 11 are assembled, the heat sink 18 is located inside the shell 11, which can better conduct the heat inside the shell 11. The heat sink 18 and the bracket 17 are arranged in an integrated manner, resulting in a seamless structure of the heat sink 18 and the bracket 17, which has good sealing and stability. When the heat dissipation fan 19 is started, the wind blown out blows through the gaps in the heat sink 18, takes away the heat on the surface of the heat sink 18, and accelerates the heat conduction of the heat sink 18. The adjacent heat sinks 18 are arranged in parallel, so that the wind blown out by the heat dissipation fan 19 can completely contact the heat sink 18, and does not cause any obstruction or interference to the wind blown out by the heat dissipation fan 19.
