Description

Technical Field

[0001] This utility model relates to the field of distribution boxes, and in particular to a JP cabinet with an S-shaped ventilation and splash-proof structure. Background Technology

[0002] Low-voltage integrated distribution boxes, abbreviated as JP cabinets, generate heat during operation due to the internal electrical components. Timely heat dissipation is crucial for their normal operation and lifespan. Traditional JP cabinet ventilation and heat dissipation structures often lack sufficient water splash protection. In rainy weather or other situations where water may splash, rainwater can easily enter the cabinet through ventilation holes, damaging internal electrical components, affecting the normal operation of the JP cabinet, and potentially causing safety accidents. Chinese patent CN109068536B discloses a waterproof outdoor communication cabinet with efficient heat dissipation and ventilation. This patent uses S-shaped heat dissipation holes in conjunction with a rain shield to prevent external water droplets from entering the cabinet, improving the safety of the internal components. As can be seen from the attached drawings of the patent, the S-shaped heat dissipation holes are horizontally arranged (the inner and outer ventilation holes are basically on the same horizontal plane). This structure has poor ventilation effect and is not conducive to dust removal. If dust is removed by tapping, the dust will accumulate in the trough of the S-shaped structure. In addition, a rain shield needs to be installed on the cabinet to prevent external water droplets from entering the cabinet, which increases the manufacturing cost of the outdoor communication cabinet and also increases the manufacturing process. Utility Model Content

[0003] The purpose of this invention is to provide a JP cabinet with an S-shaped ventilation and splash-proof structure.

[0004] The innovation of this utility model is that the JP cabinet designed in this application has an S-shaped baffle, which has good heat dissipation and good water splash resistance.

[0005] To achieve the aforementioned objectives, the technical solution of this utility model is as follows:

[0006] A JP cabinet with an S-shaped ventilation and splash-proof structure includes a cabinet body. Ventilation holes are formed in the side walls of the cabinet body. A window frame is provided along the inner edge of each ventilation hole. Several parallel S-shaped baffles are arranged at intervals along the vertical direction within the window frame. Each S-shaped baffle includes a first vertical portion connected to the inner side of the window frame, a second vertical portion connected to the outer side of the window frame, an inclined portion connecting the bottom end of the first vertical portion and the top end of the second vertical portion, and a water-blocking portion located at the top end of the first vertical portion. An S-shaped ventilation channel is formed between two adjacent S-shaped baffles. The upper part of the S-shaped ventilation channel is formed by the upper end of the inclined portion of the upper S-shaped baffle and the water-blocking portion of the next S-shaped baffle, constituting an inner ventilation opening. The lower part is formed by the lower end of the second vertical portion of the upper S-shaped baffle and the lower end of the inclined portion of the next S-shaped baffle, constituting an outer ventilation opening. The height of the inner ventilation opening is higher than the height of the outer ventilation opening.

[0007] Furthermore, the surface of the S-shaped baffle is coated with a hydrophobic coating.

[0008] Furthermore, the water-blocking part is a horizontally extending structure, or extends inclinedly from the inside of the cabinet to the outside at an angle not exceeding 10°.

[0009] Furthermore, the length of the water-blocking part does not exceed 1 / 3 of the length of the inclined part.

[0010] The beneficial effects of this utility model are:

[0011] First: The S-shaped baffle structure designed in this application is simple. The height of the inner ventilation opening of the S-shaped ventilation duct is higher than that of the outer ventilation opening. This design utilizes the principle of hot air rising (chimney effect). The heat generated by the equipment inside the cabinet during operation will cause the air to expand and decrease in density. The hot air will naturally rise. The higher position of the inner opening makes it easier to capture the hottest air that gathers at the top of the cabinet. The lower position of the outer opening is still the outlet of hot air relative to the external environment. The hot air flows into the S-shaped ventilation duct from the higher inner position. Due to its upward trend, it will naturally flow towards the outlet (outer opening) and be discharged. This structure actively guides the hot air to be discharged, resulting in higher heat dissipation efficiency.

[0012] Second: To prevent condensation / liquid from dripping directly into the cabinet, the design features a high inner side and a low outer side structure. Even if a small amount of water enters the S-shaped ventilation duct from the outer opening, the inclined section (inclined upwards) makes it more difficult for the water to flow back into the cabinet. Furthermore, this application also includes a water-blocking section, allowing the water to flow in a meandering manner along the water-blocking section. Under the combined action of gravity and the water-blocking section, the water is eventually guided to the outside of the cabinet, forming a secondary protection.

[0013] Third: The S-shaped ventilation duct designed in this application can reduce the direct settling of dust. Large dust particles will slide off the cabinet body along the inclined part of the S-shaped ventilation duct under the action of gravity. In addition, this structure is also convenient for cleaning. When cleaning by tapping, the dust will slide off the cabinet body along the inclined part and will not accumulate in the ventilation duct. Attached Figure Description

Detailed Implementation

[0019] The technical solutions in the embodiments of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0020] A JP cabinet with an S-shaped ventilation and splash-proof structure includes a cabinet body 10, ventilation holes are opened on the side wall of the cabinet body 10, a window frame 20 is provided on the inner edge of the ventilation hole, and a number of parallel S-shaped baffles 30 are arranged at intervals along the vertical direction inside the window frame 20.

[0021] Each of the S-shaped baffles 30 includes a first vertical portion 31 connected to the inner side of the window frame 20, a second vertical portion 32 connected to the outer side of the window frame 20, an inclined portion 33 connecting the bottom end of the first vertical portion 31 and the top end of the second vertical portion 32, and a water-blocking portion 34 disposed at the top end of the first vertical portion 31; an S-shaped ventilation channel 40 is formed between two adjacent S-shaped baffles 30.

[0022] The upper part of the S-shaped ventilation duct 40 is formed by the upper end of the inclined part 33 of the upper S-shaped baffle 30 and the water-blocking part 34 of the lower S-shaped baffle 30, forming an inner ventilation opening 41. The lower part is formed by the lower end of the second vertical part 32 of the upper S-shaped baffle 30 and the lower end of the inclined part 33 of the lower S-shaped baffle 30, forming an outer ventilation opening 42. The height of the inner ventilation opening 41 is higher than the height of the outer ventilation opening 42.

[0023] Furthermore, the size and location of the ventilation holes can be determined according to the size of the cabinet 10 and the heat dissipation requirements. The material of the S-shaped baffle 30 can be stainless steel, and the thickness is generally selected as 2mm, which can be thickened according to actual needs. According to the requirements of splash prevention and heat dissipation, the gap between the S-shaped baffles 30 can be determined, such as a gap of 5mm, 8mm, etc., to form an S-shaped ventilation channel 40.

[0024] Furthermore, the S-shaped baffle 30 designed in this application can be manufactured by bending stainless steel plates, which simplifies the manufacturing process.

[0025] Furthermore, the surface of the S-shaped baffle 30 is coated with a hydrophobic coating, which helps water droplets slide off.

[0026] Furthermore, the water-blocking part 34 is a horizontally extending structure, or it extends obliquely from the inside of the cabinet 10 to the outside at an angle of no more than 10°. The oblique extension of the water-blocking part 34 helps dust on the top surface of the water-blocking part 34 to slide off.

[0027] Furthermore, the length of the water-blocking part 34 does not exceed 1 / 3 of the length of the inclined part 33.

[0028] The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
