Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency power supplies, in particular to a radio frequency power supply with a built-in heat dissipation air duct. Background Art

[0002] The RF power supply is a power supply that can generate a fixed-frequency sinusoidal voltage and has a certain power. During its operation, a large amount of heat will be generated inside the shell. Therefore, it is necessary to set a corresponding heat dissipation duct inside the shell to ensure the normal operation of related parts. For example, a RF power supply with a heat dissipation duct is disclosed in Publication No. CN217159528U. The RF power supply with a heat dissipation duct includes a box body and a heat dissipation channel. A first heat dissipation hole and a first fan are arranged on the cover plate of the box body. The heat dissipation channel is arranged on the upper surface of the bottom plate of the box body. The first heat dissipation hole is connected to the heat dissipation channel. When the first fan delivers air to the inside of the box body, the hot air inside the box body can pass through the heat dissipation channel and be discharged from the first heat dissipation hole. The heat dissipation channel is arranged along the inner side of the enclosure, which can accelerate the overall heat dissipation inside the RF power supply with the heat dissipation duct, and at the same time, balanced heat dissipation can be achieved in various places inside the box body. However, the RF power supply with a heat dissipation duct still has the following disadvantages during actual use:

[0003] When traditional RF power supplies are dissipating heat, the heat dissipation position and range are mostly fixed, resulting in uneven heat distribution inside the RF power supply, poor heat dissipation effect, and the problem of dust affecting the smoothness of gas flow during the heat dissipation process. In response to the above problems, innovative designs are urgently needed based on the original RF power supply. Utility Model Content

[0004] The purpose of the utility model is to provide a radio frequency power supply with a built-in heat dissipation duct to solve the problem that the heat dissipation position and range of traditional radio frequency power supplies are mostly fixed when dissipating heat, resulting in uneven heat distribution inside the radio frequency power supply, poor heat dissipation effect, and the presence of dust in the heat dissipation process affects the smoothness of gas circulation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a radio frequency power supply with a built-in heat dissipation duct, provided with a shell, a fan is installed on the top of the shell, and a fixing box is fixed to the air outlet of the fan, the bottom of the fixing box is fixedly connected to one end of an air supply pipe, and the other end of the air supply pipe is connected to an exhaust pipe, the exhaust pipe is fixed between two partition plates, and the partition plate is fixed in the shell, a filter screen is provided between the partition plate and the shell, and the lower end surface of the filter screen is connected to each other through a traction rope and a heat dissipation window, and the heat dissipation window is hingedly provided on both sides of the shell;

[0006] It comprises: an air intake assembly, which is arranged on the fixing box and the exhaust pipe, and the air intake assembly and the exhaust pipe cooperate with each other to realize heat dissipation in the shell.

[0007] Preferably, the filter is tilted, and the lowest point of the filter is higher than the highest point of the exhaust pipe, and the filter is slidably connected to the partition plate and the shell, and the upper end surface of the filter is connected to the inner top surface of the shell through a spring.

[0008] Preferably, the fixing box is connected to each other through an air supply pipe and an exhaust pipe, and the air supply pipe is arranged obliquely, and the exhaust pipe is connected to the space between the partition plate and the shell.

[0009] Preferably, the air intake assembly includes a movable shaft with a bearing passing through the fixed box, and a fixed plate is fixed to the outer side of the movable shaft, and the fixed plates are distributed at equal angles.

[0010] Preferably, one end of the movable shaft extending outside the fixed box is connected to one end of the transmission shaft through a pulley mechanism, and the transmission shaft is rotatably arranged on a plate below the exhaust pipe, and the transmission shaft is a transverse "L"-shaped structure.

[0011] Preferably, the lower side of the exhaust pipe is fixedly connected to one end of the fixed pipe, and the other end of the fixed pipe is connected to the air intake pipe via a connecting pipe, and the connecting pipe is made of a hose material.

[0012] Preferably, the fixed pipe, the connecting pipe and the air intake pipe are all arranged at an angle, and a fixing block is arranged on the side of the air intake pipe, and two adjacent air intake pipes are fixedly connected by a connecting rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects: when the RF power supply with built-in heat dissipation duct is dissipating heat, the heat dissipation position and range can be changed accordingly, thereby ensuring the uniform temperature distribution inside the RF power supply and improving the heat dissipation effect. In addition, during the heat dissipation process, the dust inside the RF power supply can be cleaned synchronously to prevent the dust from affecting the smoothness of gas circulation. The specific contents are as follows:

[0014] 1. Hot air can blow on the filter to intercept the dust in the gas. When the filter needs to be cleaned, open the heat dissipation window and pull the filter to slide on the partition plate and the shell by pulling the traction rope. The filter can be cleaned after sliding down. After closing the heat dissipation window, the traction rope releases the pull on the filter, and the filter can be lifted up by the resilience of the spring.

[0015] 2. The gas enters the exhaust pipe from the gas delivery pipe and is transported to both ends of the exhaust pipe. In this way, the bottom of the intake pipe is in a negative pressure state, which can suck the hot air in the shell into the intake pipe, and then transmit it to the fixed pipe through the connecting pipe, and then enter the exhaust pipe for discharge, thereby realizing the discharge of heat inside the shell;

[0016] Furthermore, when the gas enters the fixed box, it can contact the fixed plate to cause the movable shaft to rotate. The movable shaft drives the transmission shaft to rotate through the pulley mechanism. When the transmission shaft rotates, it can contact the fixed block, thereby driving the intake pipe to swing through the connecting pipe. Since the connecting pipe is made of a hose material, the intake pipe can move in the opposite direction, thereby achieving the effect of changing the heat absorption range.

[0025] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0026] Embodiment 1: In order to solve the problems existing in the prior art, the present embodiment adopts the following technical scheme: a radio frequency power supply with a built-in heat dissipation duct is provided with a shell 1, a fan 2 is installed on the top of the shell 1, and a fixing box 3 is fixed to the air outlet end of the fan 2, the bottom of the fixing box 3 is fixedly connected to one end of an air supply pipe 4, and the other end of the air supply pipe 4 is connected to an exhaust pipe 5, the exhaust pipe 5 is fixed between two partition plates 6, and the partition plates 6 are fixed in the shell 1, a filter screen 7 is provided between the partition plates 6 and the shell 1, and the lower end surfaces of the filter screen 7 are connected to each other through a traction rope 8 and a heat dissipation window 9, and the heat dissipation window 9 is hingedly provided on both sides of the shell 1; it includes: an air intake assembly, which is arranged on the fixing box 3 and the exhaust pipe 5, and the air intake assembly and the exhaust pipe 5 cooperate with each other to realize heat dissipation in the shell 1.

[0027] The existing RF power supply has the problem of dust affecting the smoothness of gas flow during the heat dissipation process, such as Figure 1-Figure 3 and Figure 5 As shown, the filter screen 7 is inclined, and the lowest point of the filter screen 7 is higher than the highest point of the exhaust pipe 5, and the filter screen 7 is slidably connected to the partition plate 6 and the shell 1, and the upper end surface of the filter screen 7 is connected to the inner top surface of the shell 1 through a spring; the fixing box 3 is connected to the exhaust pipe 5 through the air supply pipe 4, and the air supply pipe 4 is inclined, and the exhaust pipe 5 is connected to the space between the partition plate 6 and the shell 1; when the absorbed hot air enters the exhaust pipe 5, the hot air can enter between the partition plate 6 and the shell 1, and The gas blows on the filter 7, which can intercept the dust in the exhausted gas, and then the hot gas continues to be transmitted and discharged from the heat dissipation window 9 to complete the heat dissipation inside the shell 1. When the filter 7 needs to be cleaned, the heat dissipation window 9 is opened, and the filter 7 is driven to slide on the partition plate 6 and the shell 1 by pulling the traction rope 8. After sliding down, the filter 7 can be cleaned. After closing the heat dissipation window 9, the traction rope 8 releases the pulling on the filter 7, and the filter 7 can be driven to rise through the resilience of the spring to intercept the dust later.

[0028] Embodiment 2: When the existing RF power supply is dissipating heat, the heat dissipation position and range are mostly fixed, resulting in uneven heat distribution inside the RF power supply and poor heat dissipation effect. Therefore, this embodiment adopts the following technical solutions, such as Figure 4-Figure 6As shown, the air intake assembly includes a movable shaft 10 with a bearing running through the fixed box 3, and a fixed plate 11 is fixed on the outer side of the movable shaft 10, and the fixed plates 11 are distributed at equal angles; one end of the movable shaft 10 extending outside the fixed box 3 is connected to one end of a transmission shaft 12 through a pulley mechanism, and the transmission shaft 12 is rotatably set on the plate below the exhaust pipe 5, and the transmission shaft 12 is a horizontal "L"-shaped structure; the lower side of the exhaust pipe 5 is fixedly connected to one end of the fixed pipe 13, and the other end of the fixed pipe 13 is connected to the air intake pipe 15 through a connecting pipe 14, and the connecting pipe 14 is made of a hose material; the fixed pipe 13, the connecting pipe 14 and the air intake pipe 15 are all inclined, and a fixing block 16 is set on the side of the air intake pipe 15, and two adjacent air intake pipes 15 are fixedly connected by a connecting rod 17; when the RF power supply is dissipating heat, the fan 2 is running to generate The gas is blown into the air delivery pipe 4 through the fixed box 3, and then the gas enters the exhaust pipe 5 and is transported to both ends thereof, so that the bottom of the intake pipe 15 is in a negative pressure state, which can suck the hot air in the shell 1 into the intake pipe 15, and then transmit it to the fixed pipe 13 through the connecting pipe 14, and then enter the exhaust pipe 5 for discharge, thereby realizing the discharge of heat inside the shell 1. When the gas enters the fixed box 3, it can contact the fixed plate 11, thereby pushing the fixed plate 11 and the movable shaft 10 to rotate. The movable shaft 10 drives the transmission shaft 12 to rotate through the pulley mechanism. When the transmission shaft 12 rotates, it can contact the fixed block 16, thereby driving the intake pipe 15 to swing through the connecting pipe 14. Since the connecting pipe 14 is made of a hose material, the transmission shaft 12 continues to rotate and no longer contacts the fixed block 16, so that the intake pipe 15 can move in the opposite direction, thereby realizing the effect of changing the heat absorption range.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
