Description

Technical Field

[0001] The utility model relates to the technical field of distribution control cabinets, and particularly relates to an efficient heat dissipation type power distribution control cabinet. Background Technique

[0002] A control cabinet assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements of the normal operation of the power system, be convenient for maintenance, and not endanger the safety of personnel and surrounding equipment. The design of the distribution control cabinet needs to consider the heat dissipation problem.

[0003] For example, the patent with the national authorized patent publication number CN219892781U discloses an efficient heat dissipation distribution control cabinet, which relates to the technical field of distribution control cabinets. To solve the problem that in the prior art, in order to obtain an efficient heat dissipation effect, most distribution control cabinets use the method of extracting internal hot air by a fan to obtain the heat dissipation effect, which leads to the need for holes and grooves between the cabinet body and the external environment, and it is easy for dust to enter the cabinet body, making it unreliable to use. One side of the cabinet body of the distribution control cabinet is provided with a thermoelectric cooler, and the thermoelectric cooler is fixedly connected with the cabinet body of the distribution control cabinet through fastening screws. One side of the thermoelectric cooler is provided with a heat conducting plate, and the heat conducting plate is attached to the thermoelectric cooler. An endothermic plate is installed inside the cabinet body of the distribution control cabinet, and the endothermic plate is fixedly connected with the cabinet body of the distribution control cabinet through fastening screws. A heat dissipation copper tube is installed inside the endothermic plate, and the heat dissipation copper tube is fixedly connected with the endothermic plate. A part of the heat dissipation copper tube is attached to the heat conducting plate.

[0004] However, for the above-mentioned efficient heat dissipation distribution control cabinet, the purpose of heat dissipation is achieved by the attachment of the copper tube and the heat conducting plate. This kind of heat dissipation mainly depends on heat conduction and natural convection. Without ventilation, heat will accumulate, resulting in an increase in the internal temperature, which will in turn affect the heat dissipation and cooling. Moreover, the copper tube and the heat conducting plate will also affect the heat dissipation effect due to dust, dirt, etc., which will bring inconvenience to subsequent cleaning and maintenance.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0027] Among them, a ventilation strip opening 101 is opened at the lower end inside the power distribution control cabinet body 1, an installation cylinder 2 is fixedly installed on the lower surface of the power distribution control cabinet body 1, a forced ventilation component 4 is fixedly installed inside the installation cylinder 2, and the forced ventilation component 4 is communicated with the ventilation strip opening 101;

[0028] Among them, windows 104 are opened on both sides inside the power distribution control cabinet body 1, an exhaust component 3 is fixedly installed between the two groups of windows 104, and the exhaust component 3 can discharge the hot air flow blown upward by the forced ventilation component 4 to the outside.

[0029] Through the design of the power distribution control cabinet body 1, ventilation slots 101, horizontal slats 102, exhaust assembly 3 and forced ventilation assembly 4, when dissipating heat from the power distribution control cabinet body 1, the forced ventilation assembly 4 can be started to suck air from the outside through the mesh holes 201 and discharge and blow it into the power distribution control cabinet body 1 from the ventilation slots 101. By discharging cold air from the bottom of the power distribution control cabinet body 1 and pushing the hot air upward, and combining it with the principle of natural upward movement of hot air, the upward movement speed of the hot air can be accelerated and sucked by the exhaust assembly 3 and discharged to the outside from the window 104, forming an air flow loop. This method utilizes the principle of cold air flowing upward to take away heat, thereby improving the heat dissipation effect. And through the function of separating multiple groups of electrical components by the horizontal slats 102, the cold air blown in from the bottom can be swept over the surface of the electrical components to take away the heat generated on the surface of the electrical components, achieving the purpose of efficient heat dissipation.

[0030] As Figures 4 - 5 shown, the forced ventilation assembly 4 includes a fan 401. The fan 401 is fixedly installed in the installation cylinder 2. The air inlet of the fan 401 is communicated with the mesh holes 201. The mesh holes 201 are opened at one end of the installation cylinder 2. The air outlet of the fan 401 is communicated with a guiding cylinder 402 installed. The guiding cylinder 402 is flush and communicated with the ventilation slot 101.

[0031] The upper surface of the guiding cylinder 402 is communicated with multiple partition cylinders 403 installed. The air outlets of the partition cylinders 403 are attached to the lower surface of the power distribution control cabinet body 1 and are flush and level with the ventilation slot 101.

[0032] The exhaust assembly 3 includes a U-shaped plate 301. The two ends of the U-shaped plate 301 are installed with exhaust frames 302 in a constricted shape. The U-shaped plate 301 is inserted and installed in the window 104 through the exhaust frames 302 on both sides, so that the middle part of the U-shaped plate 301 is overhead at the upper end inside the power distribution control cabinet body 1.

The partition cylinder 403 is attached to the ventilation slot 101 at the bottom of the power distribution control cabinet body 1. Thus, air can be accurately discharged into the power distribution control cabinet body 1 to achieve the purpose of forced ventilation. During the process of cold air being discharged from the partition cylinder 403 into the power distribution control cabinet body 1, the partition cylinder 403 can effectively disperse the airflow generated by the fan 401 in multiple directions, so as to evenly cover the heat dissipation area. This uniform airflow can more effectively take away the heat in the heat dissipation area and avoid local overheating caused by uneven air flow. The cold air blown in from the bottom will push the hot air to rise into the U-shaped plate 301, and the hot air enclosed in the U-shaped plate 301 will be inhaled by the exhaust fans 303 on both sides and discharged from the window 104. By introducing cold air from the ventilation slot 101 at the bottom of the power distribution control cabinet body 1 and discharging hot air from both sides at the upper end, a good convection channel is formed. This method utilizes the upward flow of cold air to take away the heat, thereby improving the heat dissipation effect.

[0036] Summarize and sort out the working steps of this solution according to the above technical solution: When dissipating heat from the power distribution control cabinet body 1, cold air can be inhaled into the fan 401 through the ventilation slot 101 by starting the fan 401 and accurately discharged from the partition cylinder 403 through the guiding cylinder 402. The partition cylinder 403 is attached to the ventilation slot 101 at the bottom of the power distribution control cabinet body 1. Thus, air can be accurately discharged into the power distribution control cabinet body 1 to achieve the purpose of forced ventilation. The cold air blown in from the bottom will push the hot air to rise into the U-shaped plate 301, and the hot air enclosed in the U-shaped plate 301 will be inhaled by the exhaust fans 303 on both sides and discharged from the window 104. By introducing cold air from the ventilation slot 101 at the bottom of the power distribution control cabinet body 1 and discharging hot air from both sides at the upper end, a good convection channel is formed. This method utilizes the upward flow of cold air to take away the heat, thereby improving the heat dissipation effect.

[0037] In summary: By introducing cold air from the ventilation slot 101 at the bottom of the power distribution control cabinet body 1 and discharging hot air from both sides at the upper end, a good convection channel is formed. This method utilizes the upward flow of cold air to take away the heat, thereby improving the heat dissipation effect. And through the diffusion of the partition cylinder 403, the cold air blown in from the bottom can blow over the surface of the electrical components and take away the heat generated on the surface of the electrical components, so as to achieve the purpose of efficient heat dissipation.
