Description

Technical Field

[0001] The present application relates to the field of power equipment, and in particular to a heat dissipation device for a power cabinet. Background Art

[0002] Power cabinet, also known as distribution cabinet, is an important equipment for distributing electrical energy in the power system.

[0003] Various electrical components are installed in the power cabinet. The electrical components generate heat during operation. Due to the limited space inside the power cabinet and the large number of electrical components, a large amount of heat is generated when the numerous electrical components are working, causing the temperature inside the power cabinet to rise. When the temperature inside the power cabinet is too high, the high temperature can easily affect the normal operation of the electrical components and even cause damage to the electrical components. Summary of the Invention

[0004] In order to reduce the temperature inside the power cabinet, the present application provides a heat dissipation device for the power cabinet.

[0005] The heat dissipation device of a power cabinet provided in this application adopts the following technical solution:

[0006] A heat dissipation device for an electric power cabinet includes a cabinet body, a water reservoir is provided on the top of the cabinet body, a liquid inlet pipe is provided between the water reservoir and the cabinet body, the water reservoir is connected to the interior of the cabinet body through the liquid inlet pipe, a storage pool is provided at the bottom of the cabinet body, a liquid outlet pipe is provided between the storage pool and the cabinet body, the storage pool is connected to the interior of the cabinet body through the liquid outlet pipe, a cooling hose is provided between the liquid inlet pipe and the liquid outlet pipe, and the cooling hose is arranged on the upper part of the cabinet body.

[0007] By adopting the above technical solution, the cooling hose is arranged around the power components in the cabinet, and water is passed through the cooling hose through the water reservoir, so that water flows in the cooling hose. Heat exchange is carried out between the flowing water and the power components and the hot air in the cabinet, thereby cooling the cabinet, reducing the temperature inside the power cabinet, and reducing the impact of the increased temperature inside the cabinet on the operation of the power components.

[0008] Optionally, a water supply pipe is provided on the water storage tank, and a discharge pipe is provided on the receiving tank.

[0009] Optionally, a return pipe is detachably installed between the water supply pipe and the discharge pipe.

[0010] Optionally, a heat dissipation hole is formed on the side wall of the cabinet, and the diameter of the heat dissipation hole at one end away from the cabinet is smaller than the diameter of the hole at one end facing the cabinet.

[0011] Optionally, a plurality of cooling fans are rotatably arranged in the cabinet.

[0012] Optionally, a number of connecting pipes are provided on the return pipe corresponding to the number of cooling fans, an impeller is rotatably provided in the connecting pipe, a linkage shaft is fixed on the impeller, the linkage shaft passes through the connecting pipe and the cooling hole and extends into the cabinet body, and one end of the linkage shaft extends into the cabinet body and is connected to the cooling fan.

[0013] Optionally, an opening is opened at the top of the water reservoir.

[0014] Optionally, a filter is installed at the opening of the water reservoir.

[0015] Optionally, the bottom of the water reservoir is inclined toward the liquid inlet pipe.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. Cooling hoses are laid out around the power components in the cabinet, and water is passed through a water reservoir to the cooling hoses. This allows water to flow through the cooling hoses. The flowing water exchanges heat with the power components and the hot air in the cabinet, thereby cooling the cabinet, lowering the temperature inside the power cabinet, and reducing the impact of the increased temperature inside the cabinet on the operation of the power components.

[0018] 2. The setting of the return pipe can transport the water flowing into the collection pool to the water storage tank, realizing the reuse of water resources and saving water resources;

[0019] 3. The heat dissipation holes can discharge the hot air inside the cabinet, thereby reducing the temperature inside the cabinet. The diameter of the heat dissipation holes at the end away from the cabinet is smaller than that at the end facing the cabinet, so that the hot air discharged from the cabinet enters from the large hole and exits from the small hole. The compressed air increases the air flow rate, which allows the gas to cool down faster, thereby reducing the temperature of the gas flowing out of the heat dissipation holes and reducing the impact of the hot air discharged from the heat dissipation holes on the surrounding environment outside the cabinet;

[0020] 4. The setting of the cooling fan can improve the air flow in the cabinet, so that the cold air in the cooling water pipe can be better dispersed into the cabinet, improving the cooling effect;

[0021] 5. The impeller cooperates with the linkage shaft to drive the cooling fan by driving the impeller when the return pipe transports water, thereby saving energy;

[0022] 6. An opening is opened on the top of the water tank to collect rainwater. On the one hand, it reduces the chance of rainwater falling on the cabinet and the probability of rainwater seeping into the cabinet. On the other hand, it can collect rainwater and make rational use of it. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Reference Figure 1 A water supply pipe 6 is fixedly provided on the water reservoir 1, and the water supply pipe 6 is connected to and communicated with the interior of the water reservoir 1. The water supply pipe 6 is used to connect a water source to replenish the water flowing into the cooling hose 5 for the water reservoir 1. A discharge pipe 7 is fixedly provided on the storage pool 3, and the discharge pipe 7 is connected to and communicated with the interior of the storage pool 3. The discharge pipe 7 is used to discharge excess water after storage in the storage pool 3; a return pipe 8 is detachably installed between the water supply pipe 6 and the discharge pipe 7. The setting of the return pipe 8 can transport the water flowing into the storage pool 3 to the water reservoir 1, thereby realizing the reuse of water resources and saving water resources. A power component 22 is provided on the return pipe 8. In this embodiment, the power component 22 is a power pump. The power component 22 provides power when it is necessary to transport the water in the storage pool 3 to the water reservoir 1.

[0033] Reference Figure 1, a plurality of cooling fans 10 are rotatably provided in the cabinet 0. In this embodiment, the number of cooling fans 10 is arranged according to the arrangement of the power components in the cabinet 0; a plurality of connecting pipes 11 are installed on the return pipe 8 corresponding to the number and position of the cooling fans 10. In this embodiment, the return pipe 8 is not a separate pipe. The return pipe 8 is connected to form a pipe through the connecting pipe 11. An impeller 12 is rotatably provided in the connecting pipe 11. A linkage shaft 13 is fixed on the impeller 12. The linkage shaft 13 passes through the connecting pipe 11 and the heat dissipation hole 9 and extends into the cabinet 0 The linkage shaft 13 passes through the connecting pipe 11 and is sealed to reduce the probability of water leakage. One end of the linkage shaft 13 extends into the cabinet 0 and is detachably connected to the heat dissipation fan 10. The impeller 12, the linkage shaft 13 and the heat dissipation fan 10 are coaxially arranged. When the return pipe 8 transports the water in the storage pool 3 to the water reservoir 1, the water flow drives the impeller 12 to rotate. At the same time, the impeller 12 rotates and drives the heat dissipation fan 10 to rotate through the linkage shaft 13. The rotation of the heat dissipation fan 10 drives the air in the cabinet 0 to flow, forming an airflow to reduce the temperature in the cabinet 0.

[0034] Reference Figure 1 , an opening 14 is provided on the top of the water reservoir 1. The opening 14 on the top of the water reservoir 1 can collect rainwater conveniently. On the one hand, it reduces the probability of rainwater falling on the cabinet 0 and reduces the probability of rainwater seeping into the cabinet 0. On the other hand, it can collect rainwater and make rational use of rainwater. A filter 15 is installed at the opening 14 of the water reservoir 1. The filter 15 covers the opening 14 on the water reservoir 1. The setting of the filter 15 can reduce the probability of debris falling into the water reservoir 1. The mesh of the filter 15 is smaller than all the meshes in this embodiment. The inner diameter of the pipe is large enough to prevent excessive debris from clogging the pipe. When the filter screen 15 is installed in the water reservoir 1, the upper surface of the filter screen 15 is lower than the top of the water reservoir 1, thereby forming a chamber. When rainwater passes through the filter screen 15 at a slow speed, it can temporarily collect rainwater, reducing the probability of rainwater leaving the water reservoir 1 along the filter screen 15 from the edge of the water reservoir 1; the bottom of the water reservoir 1 is inclined toward the liquid inlet pipe 2, and the inclined bottom of the water reservoir 1 can divert the water in the water reservoir 1 and reduce the sedimentation of water in the water reservoir 1.

[0035] Reference Figure 1A solenoid valve 23 is installed on the liquid inlet pipe 2, and a liquid level sensor 24 is provided in the water reservoir 1. When the liquid level in the water reservoir 1 is too high, the solenoid valve 23 is opened to discharge the water in the water reservoir 1 into the storage tank 3 through the cooling hose 5, and then discharged through the discharge pipe 7. A temperature sensor 25 is provided in the cabinet 0. When the temperature in the cabinet 0 reaches a preset value, the power component 22 is started to transport the water in the storage tank 3 to the water reservoir 1, and the solenoid valve 23 is opened at the same time, so that the water in the water reservoir 1 enters the cooling hose 5 to reduce the temperature inside the cabinet 0 through heat exchange. The power component 22, the solenoid valve 23, the temperature sensor 25 and the liquid level sensor 24 can all be connected to the computer terminal through wires, or a processing unit can be set on the cabinet 0 to receive the signals transmitted by the temperature sensor 25 and the liquid level sensor 24, and control the opening and closing of the power component 22 and the solenoid valve 23 through signal feedback.

[0036] The implementation principle of the embodiment of the present application is as follows: a cabinet body 0 is formed by welding, and a door panel 19 is installed on the cabinet body 0, and then a water reservoir 1 and a storage slot are installed on the cabinet body 0, and the cabinet body 0 is installed at the required installation position. After the cabinet body 0 is installed and fixed, a suitable number of plug-ins 21 are inserted into the cabinet body 0 according to the type and function of the power cabinet, and power components are installed on the plug-ins 21. Then, one end of the cooling hose 5 is fixedly installed on the liquid inlet pipe 2, and the cooling hose 5 is fixed along the power components. When the cooling hose 5 is laid, the total length needs to be longer than expected. After the cooling hose 5 is laid, the excess part of the cooling hose 5 is cut according to the actual required length, and then the other end of the cooling hose 5 is installed on the liquid outlet pipe 4, and the return pipe 8 is installed on the discharge pipe 7 and the water supply pipe 6, and the plug-in board 21 is installed according to the installation of the plug-in board 21. The installation position is to install the connecting pipe 11 on the return pipe 8, and pass the linkage shaft 13 on the connecting pipe 11 through the heat dissipation hole 9, and then rotate the shaft to extend into one end of the cabinet 0 to install the cooling fan 10, close the cabinet door 16, and add appropriate water to the water reservoir 1 to complete the assembly of the power cabinet. When the temperature in the cabinet 0 is too high, the solenoid valve 23 opens, allowing the water in the water reservoir 1 to enter the cooling hose 5. The flow of water in the cooling hose 5 takes away part of the heat in the cabinet 0 to cool the cabinet 0. After that, the water enters the storage tank 3 through the liquid outlet pipe 4, and is transported back to the water reservoir 1 through the return pipe 8 to cool the inside of the cabinet 0 again. During the period when the water flows back from the storage tank 3 to the water reservoir 1, the water flow will drive the impeller 12, thereby driving the cooling fan 10 to rotate, generating airflow in the cabinet 0, and improving the heat dissipation inside the cabinet 0.
