Second, the method of connecting fans through ducts requires additional fans to be installed after the cabinet is installed, which is quite cumbersome.

[0005] Therefore, we propose a heat dissipation structure and its gas pressure regulating cabinet. Utility Model Content

[0006] The present invention mainly addresses the technical problem that open heat dissipation can affect electronic components by providing a heat dissipation structure and its gas pressure regulating cabinet.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a heat dissipation structure, comprising:

[0016] Beneficial effects

[0017] This utility model provides a heat dissipation structure and its gas pressure regulating cabinet. It has the following beneficial effects:

[0018] 1. This heat dissipation structure and its gas pressure regulating cabinet draw air from vertical channels via a second fan. Several vertical channels located in front of the second fan draw in cold air from the outside. Simultaneously, the first fan discharges air downwards. The air flows vertically downwards from various lateral channels, and then flows through the air supplied by the first and second fans in a cross-shaped trajectory. During the flow, heat exchange is fully achieved. The heat exchange block has several intervals formed inside through vertical and lateral channels. These intervals act as heat exchange fins, increasing the heat exchange area of ​​the two air streams and greatly improving heat exchange efficiency and cooling effect.

[0019] 2. This heat dissipation structure and its gas pressure regulating cabinet, by fastening the heat exchange block to the cabinet body with screws through the mounting holes, achieves the installation and fixation of the heat exchange block. The right half of the heat exchange block is located outside the cabinet body, and the left half of the heat exchange block is located inside the cabinet body. The first fan is located inside the cabinet body, and the second fan is located outside the cabinet body. With the help of gaskets, the windows of the cabinet body are sealed. The second fan causes the air inside the cabinet body to flow from top to bottom. The first fan causes the air outside the cabinet body to be drawn in through a vertical channel, pass through a connecting groove, and then be discharged through another vertical channel directly opposite the second fan. This can achieve closed-loop heat dissipation inside the heat exchange block, reduce the impact of external air dust on the lifespan of the electronic components inside the cabinet body, and ensure the stability of the electronic components while ensuring the heat dissipation effect.

[0020] 3. This heat dissipation structure and its gas pressure regulating cabinet can be installed by locking the flange to the cabinet body. It is simple and quick to assemble and maintain.

[0027] A heat dissipation structure and its gas pressure regulating cabinet, such as Figure 1 and Figure 2 As shown, it includes:

[0028] A heat exchange block 10 is provided, with a first fan 11 fixedly installed at its bottom and a second fan 12 fixedly installed on its side wall.

[0029] like Figure 3 and Figure 4As shown, heat dissipation channels are set on the top and side walls of the heat exchange block 10 for air heat exchange. The heat dissipation channels include lateral channels 20, vertical channels 21, and connecting grooves 22. Several vertical channels 21 are formed on the right side wall of the heat exchange block 10, and these vertical channels 21 are interconnected through the connecting grooves 22. Several lateral channels 20 are formed on the top of the heat exchange block 10. The first fan 11 faces the lateral channels 20, and the vertical channels 21 face the second fan 12. The heat exchange block 10 forms a rectangular block, and the vertical channels 21 are rectangular grooves. The vertical channels 21 are arranged in rows and equidistantly. Each vertical channel in the same row... 21 is connected by a connecting groove 22, which is a rectangular groove. The connecting groove 22 is at the same height as the vertical channel 21 and is located at the bottom of the vertical channel 21. The connecting groove 22 and the vertical channel 21 form a U-shaped channel. The second fan 12 is fixedly installed on the side wall of the heat exchange block 10 and close to the rear wall of the heat exchange block 10. The vertical channel 21 in front of the second fan 12 is used for air intake, and the vertical channel 21 directly opposite the second fan 12 is used for exhaust. The lateral channel 20 is a rectangular groove. There is a gap between two adjacent vertical channels 21. The lateral channel 20 extends through the gap to the bottom of the heat exchange block 10.

[0030] In this scheme, the second fan 12 draws air into the vertical channel 21. Several vertical channels 21 located in front of the second fan 12 will draw in cold air from the outside. At the same time, the first fan 11 will discharge the air downwards. The air flows vertically downwards from each side channel 20. Then, the air supplied by the first fan 11 and the second fan 12 flows in a cross-shaped trajectory. During the flow, heat exchange is fully performed. The heat exchange block 10 has several intervals formed inside through the vertical channel 21 and the side channel 20. The intervals act as heat exchange fins, increasing the heat exchange area of ​​the two air streams and greatly improving the heat exchange efficiency and cooling effect.

[0031] like Figure 5 As shown, a flange 30 is fixedly installed on the outer wall of the heat exchange block 10, and a gasket 31 is fixedly installed on the right side of the flange 30. Both the flange 30 and the gasket 31 have mounting holes. The heat exchange block 10 is installed and fixed by the rectangular flange 30 and the gasket 31, which can be made of rubber. The gasket 31 is made of rubber and is fastened to the cabinet by screws through the mounting holes. The right half of the heat exchange block 10 is located outside the cabinet, and the left half of the heat exchange block 10 is located inside the cabinet. The first fan 11 is located inside the cabinet, and the second fan 12 is located outside the cabinet. Together with the gasket 31, the windows of the cabinet are sealed. The second fan 12 causes the air inside the cabinet to flow from top to bottom. The first fan 11 causes the air outside the cabinet to be drawn in through a vertical channel 21, pass through a connecting groove 22, and then be discharged through another vertical channel 21 directly opposite the second fan 12. This can achieve closed-loop heat dissipation inside the heat exchange block 10, reduce the impact of external air dust on the life of electronic components inside the cabinet, and ensure the stability of electronic components while ensuring heat dissipation.

[0032] As shown in the figure, a gas pressure regulating cabinet includes a cabinet body with a window for heat dissipation on one side. The window contains all the aforementioned heat dissipation structures. A flange 30 is bolted to the cabinet body. A heat exchange block 10 extends through the window to the outside of the heat exchange block 10. A second fan 12 is located on one side of the cabinet body. Installation can be achieved by locking the flange 30 to the cabinet body. Assembly and maintenance are simple and quick. With the aforementioned heat dissipation structures, the internal working temperature of the cabinet body can be controlled, suppressing high temperatures caused by heat accumulation, and also preventing dust from entering due to heat dissipation.

[0033] Of course, the cabinet contains a diaphragm gas meter, an intake pipe connected to the intake end of the diaphragm gas meter, and an outlet pipe connected to the outlet end of the diaphragm gas meter. The intake pipe is equipped with a temperature sensor for measuring the intake air temperature and a pressure sensor for measuring the intake air pressure. The cabinet is equipped with a control module. The control module receives the temperature signal from the temperature sensor and the pressure signal from the pressure sensor, and converts the operating volume measured by the diaphragm gas meter into the standard volume. The above-mentioned method for controlling gas pressure is a known prior art and will not be described in detail here.

[0034] The working principle of this invention is as follows: Air is drawn from the vertical channels 21 by the second fan 12. Several vertical channels 21 located in front of the second fan 12 draw in cold air from the outside. Simultaneously, the first fan 11 discharges the air downwards. The air flows vertically downwards from each lateral channel 20, and then flows in a cross-shaped trajectory due to the air supplied by the first fan 11 and the second fan 12. During this flow, sufficient heat exchange occurs. The heat exchange block 10 has several intervals formed inside through the vertical channels 21 and the lateral channels 20. These intervals act as heat exchange fins, increasing the heat exchange between the two air streams. The area is determined by screws passing through the mounting holes and fastening them to the cabinet to install and fix the heat exchange block 10. The right half of the heat exchange block 10 is located outside the cabinet, and the left half of the heat exchange block 10 is located inside the cabinet. The first fan 11 is located inside the cabinet, and the second fan 12 is located outside the cabinet. With the help of the gasket 31, the window of the cabinet is sealed. The second fan 12 causes the air inside the cabinet to flow from top to bottom. The first fan 11 causes the air outside the cabinet to be drawn in from a part of the vertical channel 21, pass through the connecting groove 22, and then be discharged from another part of the vertical channel 21 directly opposite the second fan 12.
