Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation, and in particular relates to a low-pressure liquid cooling device for a door of a rail transportation power supply switch cabinet. Background Art

[0002] The low-pressure liquid cooling device for the door of the rail transit power supply switch cabinet refers to a low-pressure liquid cooling heat dissipation device installed on the door of the rail transit power supply switch cabinet. This device is usually used for electrical equipment in the rail transit system, such as the power supply switch cabinet, to keep the equipment within the normal operating temperature range. The low-pressure liquid cooling device achieves heat dissipation through liquid circulation, effectively reducing the operating temperature of the equipment and improving the stability and reliability of the equipment.

[0003] In rail transit systems, power supply switchgear is a vital device used to control and distribute electricity. In order to ensure the normal operation of the equipment, a low-pressure liquid cooling device is usually installed on the switchgear door to keep the equipment within a suitable operating temperature range. However, the existing low-pressure liquid cooling device has some problems during use. First, the cooling effect is poor and cannot meet the heat dissipation requirements of the equipment, resulting in excessive temperature of the equipment. Secondly, dual cooling operation cannot be performed, that is, the equipment cannot be cooled at a deeper level. In addition, the coolant cannot fully contact the heat sink during circulation, affecting the heat dissipation effect. These problems may cause equipment overheating, performance degradation, or even failure. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 4 As shown, a low-pressure liquid cooling device for a door of a rail transit power supply switch cabinet comprises:

[0027] Water inlet pipe 1;

[0028] A water outlet pipe 2, which is arranged on one side of the water inlet pipe 1;

[0029] The cooling mechanism 3 is sleeved on the outside of the water inlet pipe 1 and the water outlet pipe 2. The cooling mechanism 3 includes a sleeve pipe 301, a protective pad 302 and a spiral circulation pipe 303. The sleeve pipe 301 is sleeved on the outside of the water inlet pipe 1. The sleeve pipe 301 is provided with a protective pad 302. The spiral circulation pipe 303 is connected to the inside of the protective pad 302. A connecting pipe 304 is inserted into the spiral circulation pipe 303. The spiral circulation pipe 303 is spirally arranged on the outside of the water inlet pipe 1. The connecting pipe 304 is fixedly connected to the top of the water inlet pipe 1. The spiral circulation pipe 303 is sleeved on the outside of the water inlet pipe 1.

[0030] Specifically, by connecting the circulation pump 5 to the sleeve pipe 301 , the coolant can flow through the spiral circulation pipe 303 to cool the outside of the water inlet pipe 1 and the water outlet pipe 2 .

[0031] As can be seen from the above, when the coolant is being cooled, the cooling operation can be performed through the cooling mechanism 4. When the temperature of the coolant is too high, the circulating pump 5 starts to work, so that the secondary circulating coolant can cool the outside of the water inlet pipe 1 and the water outlet pipe 2, thereby achieving multiple cooling, improving the cooling efficiency of the liquid cooling device, effectively reducing the operating temperature of the equipment, and improving the stability and reliability of the equipment.

[0032] Embodiment 2:

[0033] refer to Figure 3 and Figure 4 As shown, the top of the cooling mechanism 3 is connected to the cooling mechanism 4, the outside of the cooling mechanism 4 is provided with a circulation pump 5, the inside of the cooling mechanism 4 is provided with a circulation mechanism 6, the cooling mechanism 4 includes a fixed seat 401, heat dissipation fins 402 and a mounting seat 403, the fixed seat 401 is fixedly connected to the outside of the connecting pipe 304, the bottom end of the fixed seat 401 is connected to the mounting seat 403, the inside of the mounting seat 403 is provided with a heat dissipation fin 402, the bottom end of the mounting seat 403 is provided with a connecting seat 404, the inside of the mounting seat 403 is provided with a plurality of circulation mechanisms 6, and the outer wall of the fixed seat 401 is connected to the water inlet pipe 1 and the water outlet pipe 2.

[0034] Specifically, when liquid cooling is performed, the liquid inside the water inlet pipe 1 flows to the inside of the fixed seat 401, and the coolant is circulated through the circulation mechanism 6 at this time. After flowing to the inside of the connecting seat 404, it refluxes through the circulation mechanism 6, and is finally discharged through the water outlet pipe 2, thereby realizing contact heat dissipation between the coolant and the cooling fins 402.

[0035] Preferably, reference Figure 1-Figure 4 As shown, the circulation mechanism 6 includes a circulation plate 601, a circulation column 602 and a circulation groove 603. The circulation plate 601 is arranged inside the mounting seat 403. A plurality of circulation columns 602 are inserted inside the circulation plate 601. A circulation groove 603 is opened through the inside of the circulation column 602. The plurality of circulation columns 602 are evenly and horizontally arranged inside the circulation plate 601. The circulation groove 603 is a cylindrical through hole.

[0036] From the above, it can be seen that when the coolant circulates inside the circulation plate 601, the opening of the circulation groove 603 inside the circulation column 602 can increase the contact area between the coolant and the heat dissipation fins 402 when the coolant circulates, so that the coolant can fully contact the heat dissipation fins 402 when circulating, thereby increasing the heat dissipation effect of the coolant, thereby greatly improving the cooling efficiency of the liquid cooling device.
