Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and in particular relates to a novel heat dissipation air duct for an integrated energy storage converter and booster unit. Background Technology

[0002] With the rapid development of the energy storage market, the demand for integrated energy storage converter and step-up transformer substations is increasing daily. Most integrated energy storage converter and step-up transformer substations use dry-type transformers, which require fans and external air ducts to be installed on the outer casing for air cooling. To meet the needs of heat dissipation and air outlet, the heat dissipation ducts commonly found on the market are generally designed to be relatively large, protruding significantly from the top cover of the transformer substation.

[0003] During the loading, unloading, and hoisting of the integrated unit, the protruding air duct interferes with the hoisting ropes, making normal hoisting impossible. Therefore, it is necessary to remove the protruding air duct and seal the air outlet before shipping the unit to the site. After hoisting and installation, personnel are then arranged to install the air duct on-site. This results in significant after-sales service costs, affects the on-site construction progress, and delays the grid connection time. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a novel heat dissipation air duct for an integrated energy storage converter and boost converter.

[0005] The technical solution adopted by this utility model is as follows: A novel energy storage converter booster integrated heat dissipation air duct includes a transformer body, a top cover on the transformer body, a heat dissipation air duct installed on the outer wall of the transformer body, the air duct being located at the lower end of the top cover and not exceeding the top cover, an installation bracket installed on the inner wall of the transformer body, the installation bracket and the air duct being placed opposite each other, multiple sets of fixed louvers for blocking are welded on the air duct, and a mesh screen is also installed inside the air duct, the mesh screen being located inside the fixed louvers.

[0006] The transformer substation body is also equipped with an installation plate on its side wall. The installation plate is located between the installation bracket and the air duct. Multiple sets of self-closing louvers for gas circulation are movably installed on the installation plate. The self-closing louvers are located inside the screen.

[0007] The lower end of the air duct is provided with multiple sets of drainage holes for liquid discharge, and the drainage holes are located at the lower end of the fixed louvers.

[0008] The fixed louvers are tilted at an angle of 150 degrees, which can block large particles and most rainwater from entering.

[0009] The screen is a 20-mesh stainless steel screen to prevent small particles and external water splashes from entering.

[0010] A fan is mounted on the mounting bracket, and the fan is placed opposite the air duct.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows:

[0012] 1. Weld louver structures to the outside of the air duct to increase the protection level of the air outlet and prevent large particles of foreign objects from entering.

[0013] 2. Self-closing louvers are integrated inside the air duct. When the fan is running, the self-closing louvers open to dissipate heat and close to prevent dust and small particles from entering when the fan is stopped. Compared with filter cotton, which requires regular cleaning of dust, self-closing louvers do not require regular maintenance, reducing equipment operation and maintenance costs.

[0014] 3. The overall size of the air duct is compact and the weight is lighter, making installation time-saving and labor-saving, and the production cost is low.

[0015] 4. The duct extension dimension does not exceed the top cover of the transformer substation, so it will not affect normal hoisting. It can be installed before delivery, reducing on-site installation and after-sales service costs and saving on-site preparation time.

[0016] 5. The internal structure of the air duct ensures smooth ventilation, with a ventilation efficiency of over 50%. Attached Figure Description

[0026] like Figures 1-5 As shown, a novel integrated energy storage converter and booster unit includes a transformer substation body 1. The transformer substation body 1 is equipped with a top cover 2. A heat dissipation air duct 3 is installed on the outer wall of the transformer substation body 1. The dimensions of the air duct 3 are: width 510 mm, height 560 mm, and thickness only 100 mm. It is fixed to the outer wall of the transformer substation body 1 with 12 M10 stainless steel bolts. The air duct 3 is located at the lower end of the top cover 2 and does not extend beyond the top cover 2. An installation bracket 4 is installed on the inner wall of the transformer substation body 1. The installation bracket 4 and the air duct 3 are placed opposite each other. Multiple sets of fixed louvers 5 for blocking are welded on the air duct 3. A mesh screen 6 is also installed inside the air duct 3. The mesh screen 6 is located inside the fixed louvers 5.

[0027] The side wall of the transformer substation body 1 is also equipped with an installation plate 7, which is located between the installation bracket 4 and the air duct 3. Multiple sets of self-closing louvers 8 for gas circulation are movably installed on the installation plate 7. The self-closing louvers 8 are located inside the screen 6. The self-closing louvers 8 installed inside the air duct 3 open for heat dissipation when the fan 9 is running, and close to prevent foreign objects from entering when the fan 9 is stopped. Compared with filter cotton dust prevention, which requires regular cleaning of filter cotton dust, the self-closing louvers 8 do not require regular maintenance, reducing equipment operation and maintenance costs.

[0028] The lower end of the air duct 3 is provided with multiple sets of drainage holes 10 for liquid discharge, and the drainage holes 10 are located at the lower end of the fixed louvers 5.

[0029] The fixed louvers 5 are tilted at an angle of 150 degrees, which can block large particles and most rainwater from entering.

[0030] The mesh screen 6 is a 20-mesh stainless steel screen to prevent small particles and external splashes of water from entering.

[0031] A fan 9 is mounted on the mounting bracket 4, and the fan 9 is placed opposite the air duct 3.

[0032] Duct 3 dimensions: width 510mm, height 560mm, thickness only 100mm. It is fixed to the outer shell with 12 M10 stainless steel bolts, and the outward extension of duct 3 does not exceed the top cover 2 of the transformer substation, so it will not affect normal hoisting. It can be installed before delivery, reducing on-site installation and after-sales service costs and saving on-site preparation time. The external welded louver 5 structure of duct 3 increases the protection level of the air outlet and prevents large particles of foreign objects from entering. When the fan 9 is running, the self-closing louver 8 opens for heat dissipation. When the fan 9 is not running, the self-closing louver 8 closes to prevent dust and small particles of foreign objects from entering. Compared with filter cotton dust prevention, which requires regular cleaning of filter cotton dust, the self-closing louver 8 does not require regular maintenance, reducing equipment operation and maintenance costs.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
