Description

Technical Field

[0001] This invention relates to the field of control cabinet heat dissipation technology, specifically a dustproof heat dissipation device for a furnace-side control cabinet. Background Technology

[0002] The boiler-side control cabinet is a core component of boiler automation. Since the control cabinet is usually equipped with multiple electrical components, the simultaneous operation of these components generates a lot of heat. If heat is not dissipated in time, it will accumulate inside the control cabinet, which can easily damage the electrical components and affect the normal operation of the control cabinet.

[0003] Common dustproof and heat dissipation methods for control cabinets typically involve using heat dissipation troughs and dust filters in conjunction with cooling fans to remove heat from inside the cabinet. However, this method still requires air circulation between the control cabinet and the outside air, inevitably allowing dust to enter the cabinet. Furthermore, the heat dissipation efficiency is relatively low. Therefore, some control cabinets employ air conditioning-style cooling. In this case, the inside of the control cabinet is sealed off from outside air circulation, completely preventing dust from entering. Air conditioning also offers higher cooling efficiency, but it consumes more power, has higher costs, and a lower cost-effectiveness.

[0004] Based on this, the present invention designs a dustproof and heat dissipation device for furnace-side control cabinets to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a dustproof and heat dissipation device for furnace-side control cabinets, which achieves heat dissipation and dust prevention in the most efficient way while saving energy through a closed-loop air-cooling and air conditioning refrigeration conversion.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A dustproof and heat dissipation device for a furnace-side control cabinet includes a control cabinet. Multiple sets of internal circulation pipes are longitudinally arranged inside the control cabinet, evenly distributed on the left and right sides of the control cabinet. Upper and lower connecting boxes are respectively located at the upper and lower ends of the internal circulation pipes on the same side. The upper and lower connecting boxes are fixedly installed at the top and bottom of the outside of the control cabinet, respectively. The two sets of lower connecting boxes at the bottom are connected by a lower connecting pipe, and the two sets of upper connecting boxes at the top are connected by a connecting curved pipe and a mounting box. The lower connecting pipe, mounting box, connecting curved pipe, and the internal circulation pipes on the left and right sides form a closed loop. Heat dissipation components are installed through both the upper and lower connecting boxes, allowing external gas to pass through the heat dissipation components and exchange heat with the internal liquid.

[0007] Preferably, the heat dissipation component includes a heat exchange pipe and an air guide shroud. The upper and lower connecting boxes are configured with hollow liquid cavities. The heat exchange pipe passes through the hollow liquid cavity and its two ends are located outside the upper and lower connecting boxes. An air guide shroud is fixedly installed at one end of the heat exchange pipe, and a filter plate is provided at the other end. A negative pressure fan is provided inside the air guide shroud. The negative pressure fan enables gas to pass through the filter plate into the heat exchange pipe and then be output from the end of the air guide shroud.

[0008] Preferably, the control cabinet is equipped with an upper circulation fan and a lower circulation fan, which are respectively installed at the top and bottom of the inside of the control cabinet by bolt connection brackets, and the upper circulation fan and the lower circulation fan form convection.

[0009] Preferably, a regulating valve is fixedly installed at the middle position of each of the built-in circulation pipes, and the regulating valve can control the liquid flow rate of the built-in circulation pipes.

[0010] Preferably, a sealed cabinet door is rotatably installed on one side of the control cabinet, and the edge of the sealed cabinet door is provided with a rubber sealing strip. When the sealed cabinet door is closed, a sealed space is formed inside the control cabinet.

[0011] Preferably, a condenser is installed inside the mounting box, and temperature sensors are installed both inside and outside the control cabinet, which can detect the temperature difference between the inside and outside of the control cabinet.

[0012] Preferably, the control cabinet is equipped with a control mainboard, which can adjust the operating power of the condenser according to the temperature difference between the inside and outside of the control cabinet, and automatically turn on the condenser when the temperature inside the control cabinet is lower than the external temperature.

[0013] Preferably, a water pump is fixedly installed inside the lower connecting pipe, and the water pump can drive the water in the built-in circulation pipe to circulate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The control cabinet of this invention is located on one side of the boiler. The operation of the boiler will cause the ambient temperature outside the control cabinet to rise. When the temperature inside the control cabinet is higher than the temperature outside the control cabinet, the equipment is in a low-power heat dissipation state, and heat dissipation is only required through the heat sink. When the temperature outside the control cabinet is higher than the temperature inside the control cabinet, the equipment enters a high-power heat dissipation state, and the water is directly cooled by the heat sink in conjunction with the condenser installed in the box. The heat sink drives the external air to exchange heat with the circulating liquid in the upper and lower connecting boxes, thereby making full use of energy to cool the environment around the control cabinet. By using it in combination with air cooling, the heat dissipation equipment of the equipment can adjust its working efficiency according to the external environment, thereby reducing energy waste, improving heat dissipation quality, and reducing cost requirements.

[0015] 2. In this invention, when water enters the upper and lower connecting boxes, low-temperature external air enters the heat dissipation components. The heat dissipation components, together with the upper and lower connecting boxes, cool the water in the upper and lower connecting boxes, thereby making the temperature of the circulating liquid lower than the internal temperature of the control cabinet. At this time, the heat dissipation of the control cabinet is completed by air cooling. During the heat dissipation process, the air inside the control cabinet does not circulate with the outside, which can completely prevent external dust from entering the control cabinet and improve the dust prevention effect under air cooling conditions.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-3 The present invention provides a technical solution: A dustproof and heat dissipation device for a furnace-side control cabinet includes a control cabinet 1. Multiple sets of internal circulation pipes 2 are longitudinally arranged inside the control cabinet 1, evenly distributed on the left and right sides of the control cabinet 1. Upper connecting boxes 9 and lower connecting boxes 7 are respectively installed at the upper and lower ends of the internal circulation pipes 2 on the same side. The upper connecting boxes 9 and lower connecting boxes 7 are fixedly installed at the top and bottom of the outer side of the control cabinet 1, respectively. The two sets of lower connecting boxes 7 at the bottom are connected by a lower connecting pipe 6, and the two sets of upper connecting boxes 9 at the top are connected by a connecting curved pipe 10 and a mounting box 11. The lower connecting pipe 6, mounting box 11, connecting curved pipe 10, and the internal circulation pipes 2 on the left and right sides form a closed loop. Heat dissipation components 8 are installed through both the upper connecting boxes 9 and lower connecting boxes 7, allowing external gas to pass through the heat dissipation components 8 and exchange heat with the internal liquid.

[0021] In this invention, water circulates between the two built-in circulation pipes 2. The circulation path is: lower connecting pipe 6 → single-sided lower connecting box 7 → built-in circulation pipe 2 → upper connecting box 9 → connecting curved pipe 10 → mounting box 11 → other side upper connecting box 9 → other side built-in circulation pipe 2 → lower connecting box 7, completing a closed-loop liquid circulation. The built-in circulation pipes 2 are arranged on both sides of the control cabinet 1, exchanging heat with the air inside the cabinet, thereby cooling the inside of the control cabinet 1 through the water. When the water enters the upper connecting box 9 and the lower connecting box 7, low-temperature external air enters the heat sink 8. The heat sink 8, along with the upper and lower connecting boxes 9 and 7, cools the water inside the upper and lower connecting boxes 9 and 7, making the circulating liquid temperature lower than the internal temperature of the control cabinet 1. At this point, heat dissipation of the control cabinet 1 is achieved through air cooling. During the heat dissipation process, the air inside the control cabinet 1 does not circulate with the outside, completely preventing external dust from entering the control cabinet 1 and improving the dustproof effect under air cooling conditions. The control cabinet 1 of this invention is located on one side of the boiler. When the boiler is working, the ambient temperature outside the control cabinet 1 will rise. When the internal temperature of the control cabinet 1 is higher than the external temperature, the equipment is in a low-power heat dissipation state, and heat dissipation is only required through the heat sink 8. When the external temperature of the control cabinet 1 is higher than the internal temperature, the equipment enters a high-power heat dissipation state, and the water is directly cooled by the heat sink 8 in conjunction with the condenser inside the mounting box 11. The heat sink 8 drives the external air to exchange heat with the circulating liquid in the upper connecting box 9 and the lower connecting box 7, thereby making full use of energy to cool the environment around the control cabinet 1. By using it in combination with air cooling, the heat dissipation equipment of the equipment can adjust its working efficiency according to the external environment, thereby reducing energy waste, improving heat dissipation quality, and reducing cost requirements.

[0022] The heat dissipation component 8 includes a heat exchange pipe 802 and an air guide shroud 801. The upper connecting box 9 and the lower connecting box 7 are configured with hollow liquid cavities. The heat exchange pipe 802 passes through the hollow liquid cavity and its two ends are located outside the upper connecting box 9 / lower connecting box 7. One end of the heat exchange pipe 802 is fixedly installed with the air guide shroud 801, and the other end is provided with a filter plate. A negative pressure fan is installed inside the air guide shroud 801. The negative pressure fan enables the gas to pass through the filter plate and enter the heat exchange pipe 802, and then be output from the end of the air guide shroud 801. In this invention, the negative pressure fan inside the air guide shroud 801 causes the gas around the control cabinet 1 to enter the heat exchange tube 802. The gas entering the heat exchange tube 802 exchanges heat with the liquid in the upper connecting box 8 and the lower connecting box 7. When the ambient temperature is low, the gas in the heat exchange tube 802 absorbs the heat from the liquid and cools the liquid. When the ambient temperature around the control cabinet 1 is stable and high, the circulating liquid in the hollow liquid cavity absorbs the heat from the gas in the heat exchange tube 802, thus preventing the ambient temperature of the control cabinet 1 from becoming too high and interfering with the normal operation of the control cabinet.

[0023] The control cabinet 1 is equipped with an upper circulating fan 5 and a lower circulating fan 4. The upper circulating fan 5 and the lower circulating fan 4 are respectively installed on the top and bottom of the inner side of the control cabinet 1 by bolted connection brackets, and the upper circulating fan 5 and the lower circulating fan 4 form convection. In this invention, when the control cabinet 1 is working, the upper circulating fan 5 and the lower circulating fan 4 are turned on simultaneously, forming convection from top to bottom, which makes the heat distribution inside the control cabinet 1 more uniform and avoids local heat accumulation, which could damage electrical components.

[0024] In this invention, a regulating valve 3 is fixedly installed at the middle position of each built-in circulation pipe 2. The regulating valve 3 can control the liquid flow rate of the built-in circulation pipe 2. When heat dissipation in the control cabinet 1 is not urgent, the liquid circulation speed can be reduced by adjusting the valve of the regulating valve 3 on the built-in circulation pipe 2, so that the equipment can maintain a stable low-power operation state.

[0025] The control cabinet 1 has a rotatable sealed door 12 mounted on one side. The edge of the sealed door 12 is equipped with a rubber sealing strip. When the sealed door 12 is closed, a sealed space is formed inside the control cabinet 1. In this invention, the sealed door 12 facilitates equipment maintenance and disassembly, and the rubber sealing strip ensures that the inside of the control cabinet 1 is sealed when the sealed door 12 is closed, making it difficult for dust to enter.

[0026] The mounting box 11 contains a condenser, and temperature sensors are installed both inside and outside the control cabinet 1. These temperature sensors can detect the temperature difference between the inside and outside of the control cabinet 1. In this invention, the temperature sensor measures the temperature difference between the inside and outside of the control cabinet 1, thereby facilitating the adjustment of the equipment to a high-frequency or low-frequency heat dissipation mode.

[0027] The control cabinet 1 is equipped with a control mainboard, which can adjust the condenser's operating power according to the temperature difference between the inside and outside of the control cabinet 1. When the internal temperature of the control cabinet 1 is lower than the external temperature, the condenser automatically turns on. In this invention, when the condenser is operating at high frequency, the circulating liquid cools the water after entering the installation box 11 through the connecting curved pipe 10.

[0028] A water pump is fixedly installed inside the lower connecting pipe 6, which can drive the water in the built-in circulation pipe 2 to circulate.
