Description

Technical Field

[0001] This invention relates to the field of electrical cabinet technology, and more particularly to a heat dissipation electrical cabinet. Background Technology

[0002] Electrical cabinets are used to install electrical components. The operation of these components generates heat, and if this heat is not dissipated in time, the internal temperature of the cabinet will rise, adversely affecting the operation of the electrical components and potentially causing a fire. Therefore, various electrical cabinets with heat dissipation functions have been developed in the prior art. For example, Chinese invention patent CN106954357A discloses a green and environmentally friendly electrical control cabinet, including a cabinet body, a mounting plate for fixing electrical components inside the cabinet body, and a door on one side of the cabinet body. A partition is fixedly installed at the top of the cabinet's internal cavity, and a first water collection tank is fixedly installed on top of this partition. A placement cylinder is fixedly installed on the top of the first water collection tank, and an installation sleeve is fixedly installed in the middle of the inner cavity of the placement cylinder. This invention utilizes a heat-conducting rod inside a second water collection tank on one side of the frame plate, a spiral plate on the surface of the heat-conducting rod, a heat-collecting plate at one end of the heat-conducting rod inside the frame, and a heat-collecting cylinder at the other end of the heat-conducting rod inside the frame. The heat-collecting plate and heat-collecting cylinder contact the air inside the cabinet, thereby increasing the absorption of heat inside the electrical control cabinet and improving the dissipation of heat. This ensures the safe use of electrical components in the electrical control cabinet and avoids accidents caused by overheating of electrical components. The electrical cabinet provided by this invention uses water as a heat exchange medium to absorb heat and then discharges the absorbed water to achieve heat dissipation. Therefore, a continuous water supply is required, which may lead to a continuous waste of water resources. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a heat dissipation electrical cabinet that solves the problem that existing electrical cabinets using water as the heat exchange medium require continuous water supply and discharge, which may lead to continuous waste of water resources.

[0004] According to an embodiment of the present invention, a heat dissipation electrical cabinet includes:

[0005] The cabinet body has several mounting plates fixedly connected inside the cabinet body. The mounting plates are arranged sequentially from top to bottom and several first support sleeves are fixedly connected between adjacent mounting plates. Each first support sleeve has a first through hole connecting its inside and outside.

[0006] The heat-conducting columns are multiple vertically arranged within the cabinet body, with the upper and lower ends of each heat-conducting column extending outside the cabinet body. All the first support sleeves between two adjacent mounting plates are respectively fitted over one of the heat-conducting columns.

[0007] A water collection tank is fixedly installed above the cabinet body, and the upper ends of all the heat-conducting columns extend into the water collection tank.

[0008] A cooling element is located below the cabinet body, and the lower ends of all the heat-conducting columns are connected to the cooling element.

[0009] A water pump, wherein the pump outlet pipe of the water pump is connected to the water collection tank and the pump inlet pipe is connected to the water source;

[0010] Each of the heat-conducting columns includes a hollow section and a solid section. The upper end of the hollow section is connected to the water collection tank, and the lower end is located on the cabinet body and fixedly connected to the solid section. The end of the solid section away from the hollow section is connected to the cooling body. The portion of the hollow section located outside the cabinet body is also provided with a second through hole.

[0011] The cabinet body in this embodiment is similar to the cabinets in the prior art, both being the main body of an electrical cabinet. Electrical components are installed inside the cabinet body. Initially, water can be used as the heat exchange medium, similar to the prior art (i.e., the electrical cabinet in the invention provided by CN106954357A). Specifically, in this embodiment, water is pumped from a water source to a water collection tank, then enters the hollow section of the heat-conducting column, flows through the hollow section, and exits to the outside of the cabinet body through the second through-hole, thereby achieving water cooling of the cabinet body. The difference between this embodiment and the prior art is that the heat-conducting column in this embodiment is directly located in the same space as the electrical components (i.e., inside the cabinet body). This allows for more direct and efficient heat transfer between the electrical components and the heat-conducting column. Specifically, as water flows through the hollow section, it efficiently removes heat from the space. Furthermore, the heat-conducting column in this embodiment can also transfer heat from inside the cabinet upwards or downwards to the outside. Additionally, the hollow section of the heat-conducting column in this embodiment allows for airflow, using air as the heat exchange medium for heat transfer between the electrical components and the heat-conducting column. Therefore, the electrical cabinet provided in this embodiment has multiple heat dissipation modes that can be selected according to heat dissipation needs, thus avoiding the problem of continuous water waste that might result from continuous water supply.

[0012] Furthermore, the mounting plate is provided with a mezzanine space, which is externally connected to the cabinet body, and a connecting pipe is provided between each mezzanine space and each hollow section to connect them.

[0013] Furthermore, the mounting plate has a connecting hole surrounding each heat-conducting pillar, and the upper and lower ends of each connecting hole are respectively connected to the two first support sleeves above and below.

[0014] Furthermore, the two ends of the connecting pipe are respectively connected to the interlayer space and the hollow section, and the middle section is located inside the connecting pipe, wherein at least two connecting pipes are provided inside each connecting pipe.

[0015] Furthermore, each of the connecting pipes extends one end into the hollow section, and the end of the connecting pipe located in the hollow section is fixedly connected to a liquid receiving hopper communicating with the connecting pipe. The end of the liquid receiving hopper facing away from the connecting pipe extends upward, and the upper end of the liquid receiving hopper is larger than its lower end.

[0016] Furthermore, a connecting sleeve is also provided inside the connecting hole and fixedly sleeved outside the heat-conducting column. A connecting column is fixedly connected between the connecting sleeve and the mounting plate. The connecting column is located inside the connecting hole, and at least two connecting columns are provided in each connecting hole.

[0017] Furthermore, both ends of each mounting plate extend outside the cabinet body, and both ends of the mounting plate outside the cabinet body are fixedly connected to an open flow guide hood. The open flow guide hood communicates with the interlayer space, and the end of the open flow guide hood facing away from the interlayer space is larger than the other end.

[0018] Furthermore, a plurality of second support sleeves are fixedly connected between the uppermost mounting plate and the inner top surface of the cabinet body, and are sleeved on the outside of each heat-conducting column. The upper end of each second support sleeve extends to the top of the cabinet body and is fixedly connected to the outer bottom surface of the water collection tank. Each second support sleeve is also provided with a third through hole located inside the cabinet body and communicating with the inside and outside of the second support sleeve. A plurality of third support sleeves are fixedly connected between the lowermost mounting plate and the inner bottom surface of the cabinet body, and are sleeved on the outside of each heat-conducting column. Each third support sleeve is also provided with a fourth through hole communicating with its inside and outside.

[0019] Furthermore, a support plate is fixedly connected to the outer bottom surface of the cabinet body, and a number of support columns are fixedly connected to the support plate to lift the support plate off the ground; the cooling body includes an inner soil layer located below the support plate, the hollow section is located above the ground, and the solid section is inserted into the inner soil layer.

[0020] Furthermore, the water source includes one of an underground river, a stream, and a water tank, and the heat-conducting column also includes a connecting section, which is fixedly connected to the solid section and extends through the inner layer of soil into the water source at one end opposite to the solid section.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) Heat dissipation is achieved by combining water cooling with heat conduction columns, air cooling with heat conduction columns, and multiple modes of heat conduction columns, thus avoiding the problem of continuous water waste that may result from continuous water use;

[0023] 2) The internal space of the cabinet is isolated from the external space, which can provide better dustproof, waterproof and pest-proof functions while playing a role in heat dissipation, ensuring the normal operation of the electrical cabinet. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

Therefore, they should not be construed as limitations on this invention.

[0035] like Figure 1 , 2 As shown in figures 3, 4, 5, 6, and 7, this embodiment provides a heat dissipation electrical cabinet, which includes:

[0036] Cabinet body 1, a plurality of mounting plates 2 are fixedly connected inside the cabinet body 1, the mounting plates 2 are arranged sequentially from top to bottom and a plurality of first support sleeves 3 are fixedly connected between adjacent mounting plates 2, and each first support sleeve 3 is provided with a first through hole 4 connecting its inside and outside.

[0037] Heat-conducting columns 5, which are multiple vertically arranged inside the cabinet body 1, with the upper and lower ends of each heat-conducting column 5 extending to the outside of the cabinet body 1 respectively, and all the first support sleeves 3 between two adjacent mounting plates 2 respectively fitted over one of the heat-conducting columns 5.

[0038] Water collection tank 6 is fixedly installed above the cabinet body 1, and the upper ends of all the heat-conducting columns 5 extend into the water collection tank 6;

[0039] The cooling body is located below the cabinet body 1, and the lower ends of all the heat-conducting columns 5 are connected to the cooling body;

[0040] Water pump 7, wherein the pump outlet pipe 8 of the water pump 7 is connected to the water collection tank 6 and the pump inlet pipe 9 is connected to the water source;

[0041] Each of the heat-conducting columns 5 includes a hollow section 10 and a solid section 11. The upper end of the hollow section 10 is connected to the water collection tank 6, and the lower end is located on the cabinet body 1 and fixedly connected to the solid section 11. The end of the solid section 11 facing away from the hollow section 10 is connected to the cold body. The part of the hollow section 10 located outside the cabinet body 1 is also provided with a second through hole 12.

[0042] In this embodiment, the cabinet body 1 is similar to the cabinet in the prior art, both being the main body of an electrical cabinet. Electrical components are installed inside the cabinet body 1. Initially, water can be used as the heat exchange medium, similar to the prior art (i.e., the electrical cabinet in the invention provided by CN106954357A). Specifically, in this embodiment, water is pumped from a water source to a water collection tank 6 via a water pump 7, and then enters the hollow section 10 of the heat-conducting column 5. After flowing through the hollow section 10, it flows out of the cabinet body 1 through the second through hole 12, thereby achieving water cooling of the cabinet body 1. The difference between this embodiment and the prior art is that in this embodiment, the heat-conducting column 5 is directly placed in the same space as the electrical components (i.e., inside the cabinet body 1), enabling more direct and efficient heat transfer between them. That is, when the water flows through the hollow section 10, the water can... The heat dissipation is more efficient in removing heat from the space. The difference lies in the fact that the heat-conducting column 5 in this embodiment can also transfer heat from inside the cabinet body 1 upwards or downwards to the outside of the cabinet body 1. Furthermore, the hollow section 10 of the heat-conducting column 5 in this embodiment can also allow airflow, using air as the heat exchange medium to transfer heat between the electrical components. Therefore, the electrical cabinet provided in this embodiment has multiple heat dissipation modes, which can be selected according to heat dissipation needs, thereby avoiding the problem of continuous water waste that may result from continuous water supply. Specifically, the heat dissipation modes provided in this embodiment mainly include two types: a combination of water cooling and heat-conducting column 5, and a combination of air cooling (i.e., wind cooling) and heat-conducting column 5. When the airflow speed is low (i.e., no wind or low wind speed), heat dissipation can also rely on the heat-conducting column 5 alone.

[0043] In this embodiment, the mounting plate 2 is used to install electrical components, while the first support sleeve 3 is fixedly connected to the middle section of the mounting plate 2 inside the cabinet body 1 (the two ends of the mounting plate 2 are fixedly connected to the cabinet body 1 to ensure stability), thereby strengthening the stability of the internal support structure of the cabinet body 1 (i.e., all the mounting plates 2). At the same time, by fitting the first support sleeve 3 outside the heat-conducting column 5, the space utilization efficiency is further improved, avoiding more occupation of the internal space of the cabinet body 1. The first through hole 4 provided on the first support sleeve 3 serves to allow heat to enter the first support sleeve 3 and exchange heat with the heat-conducting column 5 and the heat exchange medium (water or air) inside the heat-conducting column 5 (i.e., inside the hollow section 10).

[0044] In particular, the water collection tank 6 in this embodiment also allows rainwater to enter during rain, so that the rainwater flows into the hollow section 10 to play a role in heat dissipation.

[0045] like Figure 1 , 2As shown in 3, 4, 5, 6, and 7, preferably, the mounting plate 2 in this embodiment is provided with a mezzanine space 13. The mezzanine space 13 is connected to the outside of the cabinet body 1. Each mezzanine space 13 and each hollow section 10 are respectively provided with a connecting pipe 14 connecting them. That is, the mezzanine space 13 in the mounting plate 2 acts as a channel, so that the outside of the cabinet body 1 is connected to the inside of the hollow section 10 through the mezzanine space 13 and the connecting pipe 14. Water in the hollow section 10 can enter the mezzanine space 13. Since the electrical components are installed on the mounting plate 2, the water in the mezzanine space 13 can exchange heat with the electrical components more efficiently. After heat exchange, the water flows out of the cabinet body 1 through the end of the mezzanine space 13 away from the connecting pipe 14, which can improve the water cooling efficiency.

[0046] On the other hand, the mezzanine space 13 also allows external air to enter, and then enters the hollow section 10 through the connecting pipe 14, thus forming a more interconnected hollow channel within the cabinet body 1 for airflow, thereby improving the efficiency of air heat dissipation. Furthermore, both ends of each mounting plate 2 extend outside the cabinet body 1, and both ends of the mounting plate 2 located outside the cabinet body 1 are fixedly connected to an open air guide hood 15. The open air guide hood 15 is connected to the mezzanine space 13, and the end of the open air guide hood 15 facing away from the mezzanine space 13 is larger than the other end. The open air guide hood 15 can allow air to enter the mezzanine space. The 13 serves to concentrate airflow. In particular, when water is scarce and the wind speed is slow, a fan can be installed in front of the open guide shroud 15 to blow air into the open guide shroud 15, thereby improving airflow efficiency and accelerating air cooling. In particular, several support blocks 16 are provided in the interlayer space 13 to strengthen the overall strength of the mounting plate 2 and prevent the mounting plate 2 from being crushed due to the installation of motor components, which would cause the interlayer space 13 to be squeezed. In particular, the support blocks 16 are not connected to each other to avoid the existence of non-connected parts in the interlayer space 13, so that the heat exchange medium (i.e., water or air) filling the entire mounting plate 2 can play a role in heat dissipation.

[0047] like Figure 1 , 2 As shown in Figures 3, 4, 6, and 7, preferably, the mounting plate 2 has a connecting hole 17 surrounding each heat-conducting column 5, and the upper and lower ends of each connecting hole 17 are respectively connected to the two first support sleeves 3 above and below. The connecting holes 17 connect the multiple spaces divided by the mounting plate 2 inside the cabinet body 1, forming a heat dissipation space inside the cabinet body 1, thereby enabling overall heat dissipation of the internal space of the cabinet body 1. In particular, the electrical components on the upper and lower parts of the mounting plate can exchange heat with the air or water in the interlayer space 13, resulting in a larger heat exchange area and higher heat dissipation efficiency.

[0048] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, preferably, both ends of the connecting pipe 14 are connected to the interlayer space 13 and the hollow section 10, respectively, and the middle section is located inside the connecting pipe 14. Each connecting pipe 14 contains at least two connecting pipes 14. The connecting pipes 14 serve to connect the interlayer space 13 and the hollow section 10, while also connecting the hollow section 10 to the mounting plate 2. This arrangement makes the connection structure between the heat-conducting column 5 and the mounting plate 2 more stable, even if the upper and lower ends of the heat-conducting column 5 are located outside the cabinet body 1. It is also not easy to dismantle. Therefore, the heat-conducting column 5 in this embodiment can be made of copper or silver, which have better thermal conductivity. In comparison, copper has better mechanical stability and is cheaper. Therefore, it is more reasonable and efficient to use copper to manufacture the heat-conducting column 5. Furthermore, a protective sleeve 36 is provided at the lower end of the heat-conducting column 5 so that the lower end of the heat-conducting column 5 is not directly exposed to the outside to avoid attracting the attention of thieves. A hole is provided on the protective sleeve 36 so that the second through hole 12 can be connected to the outside normally, which can serve to drain water or allow air to pass through.

[0049] Specifically, in this embodiment, a cover 18 corresponding to each heat-conducting column 5 is threadedly connected inside the water collection tank 6. The upper end of each hollow section 10 is respectively wrapped inside a cover 18. The top surface of the cover 18 is closed and holes are opened on its peripheral wall. Water enters through the holes to further enter the corresponding hollow section 10. This can prevent the heat-conducting column 5 from being exposed, thereby preventing theft. Furthermore, the cover 18 can also play a filtering role. Furthermore, a filter screen 19 can be covered on the top surface of the water collection tank 6 to prevent impurities from entering the water collection tank 6. At the same time, the cover 18 can also be easily disassembled to clean the holes on it.

[0050] Furthermore, a connecting sleeve 20 is also provided inside the connecting hole 17, which is fixedly sleeved outside the heat-conducting column 5. A connecting column 21 is fixedly connected between the connecting sleeve 20 and the mounting plate 2. The connecting column 21 is located inside the connecting hole 17, and at least two connecting columns 21 are provided in each connecting hole 17. The setting of the connecting column 21 makes the connection between the mounting plate 2 and the heat-conducting column 5 more stable. Furthermore, the connecting column 21 can be set in two layers above and below the corresponding interlayer space 13, which further strengthens the connection stability between the mounting plate 2 and the hollow section 10. The upper and lower ends of the connecting sleeve 20 extend to the outside of the connecting hole 17 and are connected to the hollow section 10 through the screw 22. That is, the connecting sleeve 20 is fixed to the hollow section 10 by the screw 22, thereby further ensuring the connection strength between the heat-conducting column 5 and the mounting plate 2, and ensuring that the heat-conducting column 5 is not easily removed by thieves.

[0051] like Figure 1 , 2As shown in Figures 3, 4, and 7, preferably, one end of each of the connecting pipes 14 extends into the hollow section 10, and the end of the connecting pipe 14 located in the hollow section 10 is fixedly connected to a liquid receiving hopper 23 communicating with the connecting pipe 14. The end of the liquid receiving hopper 23 facing away from the connecting pipe 14 extends upward, and the upper end of the liquid receiving hopper 23 is larger than its lower end. The liquid receiving hopper 23 is provided to guide the water entering the hollow section 10 so that the water enters the corresponding connecting pipe 14 and then enters the interlayer space 13 in the mounting plate 2. At the same time, the liquid receiving hopper 23 also plays a role in obstructing the flow of water, preventing the water from flowing down through the hollow section 10 to the second through hole 12 and then being directly discharged, thereby allowing the water to stay in the cabinet body 1 for a slightly longer time, so as to ensure more efficient heat exchange.

[0052] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, preferably, a plurality of second support sleeves 24 are fixedly connected between the uppermost mounting plate 2 inside the cabinet body 1 and the inner top surface of the cabinet body 1, and are sleeved on the outside of each heat-conducting column 5. The upper end of each second support sleeve 24 extends above the cabinet body 1 and is fixedly connected to the outer bottom surface of the water collection tank 6. Each second support sleeve 24 is also provided with a third through hole 25 located inside the cabinet body 1 and communicating with the inside and outside of the second support sleeve 24 (all third through holes 25 are located inside the cabinet body 1). A plurality of third support sleeves 26 are fixedly connected between the lowermost mounting plate 2 inside the cabinet body 1 and the inner bottom surface of the cabinet body 1, and are sleeved on the outside of each heat-conducting column 5. Each third support sleeve 26 is also provided with a fourth through hole 27 communicating with its inside and outside. Similar to the first support sleeve 3, the second support sleeves 24 and the third support sleeves 26 enable the corresponding mounting plate 24 to support the water collection tank 6. The connection strength between the mounting plate 2 and the cabinet body 1 is strengthened. At the same time, the third through hole 25 and the fourth through hole 27, similar to the first through hole 4, serve to allow heat to enter the second support sleeve 24 (and the third support sleeve 26) and exchange heat with the heat-conducting column 5 and the heat exchange medium (water or air) inside the heat-conducting column 5 (i.e., inside the hollow section 10). In particular, the second support sleeve 24 also serves to support the water collection tank 6, so that a certain gap can be formed between the water collection tank 6 and the outer top surface of the cabinet body 1. Furthermore, the top of the cabinet body 1 is also fixedly connected to the fourth support sleeve 28, which is sleeved outside the second support sleeve 24. The fourth support sleeve 28 is fixedly connected to the water collection tank 6. In this way, the weight of the water collection tank 6 is borne by the second support sleeve 24 and the fourth support sleeve 28, and the water is diverted to the top of the mounting plate 2 and the cabinet body 1 located on the highest layer, avoiding the phenomenon of the top surface of the cabinet body 1 sinking due to heavy pressure.

[0053] like Figure 1 , 2As shown in 3, 4, 5, 6, and 7, preferably, a support plate 30 is fixedly connected to the outer bottom surface of the cabinet body 1, and a plurality of support columns 31 are fixedly connected to the support plate 30 to lift the support plate 30 off the ground; the cooling body includes an inner soil layer 32 located below the support plate 30, the hollow section 10 is located above the ground, and the solid section 11 is inserted into the inner soil layer 32. The support plate 30 provides the installation foundation for the cabinet body 1 to be installed. The lower end of the hollow section 10 is located below the support plate 30, wherein the second through hole 12 is located below the support plate 30 for water discharge. The solid section 11 is inserted into the inner soil layer 32. The temperature in the inner soil layer 32 is generally lower than that in the cabinet body 1. Therefore, the heat inside the cabinet body 1 can be conducted to the soil through the heat-conducting column 5, which plays a role in heat dissipation. More importantly, this heat conduction (i.e., the heat conduction) exists in both air-cooled and water-cooled modes and continues. When the heat dissipation demand inside the cabinet body 1 is generally low, heat can be conducted through the heat-conducting column 5.

[0054] Furthermore, the water source includes one of an underground river, a stream 29, and a water storage tank 34. The heat-conducting column 5 also includes a connecting section 33, which is fixedly connected to the solid section 11, and one end of the connecting section 33 facing away from the solid section 11 extends through the inner soil layer 32 into the water source. This allows the heat-conducting column 5 in this embodiment to directly connect with the cooler stream 29, underground river, or water storage tank 34 via the connecting section 33. (Comparatively, an underground river is more difficult to achieve, and a stream 29 requires the electrical cabinet to be installed beside a stream. If underground rivers and streams are difficult to achieve, an artificial water storage tank 34 can be set up next to the electrical cabinet to store water. Furthermore, cooling measures can be added to further enhance the cooling effect.) The water in the water storage tank 34 is cooled, for example by using a refrigeration system or by burying the water storage tank 34 in the inner layer 32 of the soil. In particular, a filter plate 35 can be installed on the top surface of the water storage tank 34 and covered with soil. After the water pump 7 reaches the water collection tank 6, it flows downward through the mounting plate 2 and the second through hole 12, and then seeps through the soil and returns to the water storage tank 34 through the filter plate 35. This can form a cycle and avoid water waste. Similarly, the water can also flow back to the underground river or stream 29 by using the method of underground river or stream 29, which can also reduce water waste. This connection further enhances the heat dissipation effect, ensuring that heat dissipation can be achieved by heat conduction through the heat conduction column 5 when the heat dissipation demand is normal.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
