Description

Technical Field

[0001] The utility model relates to a field, in particular to an electrical control cabinet, and more particularly to a control cabinet cooling circulation device. Background Art

[0002] In the existing technology, the control cabinet relies on air for heat dissipation and needs to leave ventilation holes, so it cannot achieve good waterproof and dustproof performance. In some relatively humid and dusty environments, it may cause damage to the control cabinet, short circuit and even casualties. This is especially true in the water pump industry. If the control cabinet and water pump are installed in the same pump room, water pump leakage may cause electric shock hazards. Summary of the Invention

[0003] The purpose of the utility model is to provide a control cabinet cooling circulation device, which solves the technical problem that the control cabinet in the prior art cannot achieve relatively good waterproof and dustproof performance due to the need to reserve ventilation holes.

[0004] The utility model discloses a control cabinet cooling circulation device, comprising a cabinet body, an outer shell being provided on the outer side of the cabinet body, a cooling pipe being provided in a cavity between the cabinet body and the outer shell, the cooling pipe being wrapped around the outer side of the cabinet body in a zigzag shape, one end of the cooling pipe being connected to one end of a cooling device, the other end of the cooling device being connected to one end of a circulating water pump, and the other end of the circulating water pump being connected to the other end of the cooling pipe; the cooling device comprising a cooling water tank, the cooling pipe passing through the cooling water tank and being immersed in the water of the cooling water tank; or the cooling device being composed of a cooling fin and a fan cooling integrated device; or the cooling device comprising an underground pipe, the underground pipe being zigzag and being provided in a constant temperature layer below the ground.

[0005] Furthermore, the cooling pipe is arranged in a zigzag shape in the cooling water tank.

[0006] Furthermore, the cooling pipe is wrapped around the left side, the rear side and the right side of the cabinet.

[0007] Compared with the existing technology, the effect of this utility model is positive and obvious. This utility model transforms a single-layer control cabinet into a double-layer control cabinet, selects metal materials with good heat dissipation performance, and adds cooling pipes inside to ensure that circulating water can flow through almost the entire cabinet surface in one direction, taking away the heat generated inside. The cooling water in the cooling pipe is circulated to the cooling device by a circulating pump for cooling, and then returns to the cabinet to form a circulation loop, thereby solving the heat dissipation problem. No ventilation holes are required on the outside of the cabinet, and the interior is completely sealed. The highest protection level can reach IP68, which can ensure the performance and safety of the control cabinet in special occasions (humid, dusty, etc.). BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following is a further description of the present invention in conjunction with an embodiment. However, the present invention is not limited to the embodiment. All similar structures and similar variations of the present invention should be included in the scope of protection of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of clear description and does not limit the technical solution of the present invention.

[0016] like Figure 1-Figure 7 As shown, a control cabinet cooling circulation device of the present invention includes a cabinet body 1, an outer shell 4 is provided on the outer side of the cabinet body 1, a cooling pipe 2 is provided in the cavity between the cabinet body 1 and the outer shell 4, the cooling pipe 2 is wrapped around the outer side of the cabinet body 1 in a zigzag shape, one end of the cooling pipe 2 is connected to one end of a cooling device, the other end of the cooling device is connected to one end of a circulating water pump 3, and the other end of the circulating water pump 3 is connected to the other end of the cooling pipe 2; the cooling device includes a cooling water tank 5, the cooling pipe 2 passes through the cooling water tank 5 and is immersed in the water in the cooling water tank 5; or, the cooling device is composed of a cooling fin and a fan cooling integrated device 6; or, the cooling device includes an underground pipe 7, the underground pipe 7 is zigzag and is arranged in a constant temperature layer below the ground 8.

[0017] Furthermore, the cooling pipe 2 is arranged in a zigzag shape in the cooling water tank 5 .

[0018] Furthermore, the cooling pipe 2 is wrapped around the left side, rear side and right side of the cabinet 1 .

[0019] Specifically, the cabinet 1, cooling device, circulating water pump 3, cooling water tank 5, cooling fins and fan cooling integrated device 6 in this embodiment all adopt well-known solutions in the prior art, which are well understood by those skilled in the art and will not be described in detail here.

[0020] The working principle of this embodiment is as follows:

[0021] The utility model transforms a single-layer control cabinet into a double-layer control cabinet, selects metal materials with good heat dissipation performance, and adds a cooling pipe 2 inside to ensure that circulating water can flow through almost the entire surface of the cabinet 1 in one direction to take away the heat generated inside. The cooling water in the cooling pipe 2 is circulated to the cooling device by a circulating pump for cooling, and then returns to the cabinet 1 to form a circulation loop, thereby solving the heat dissipation problem. No ventilation holes are required on the outside of the cabinet 1, and the interior is completely sealed. The highest protection level can reach IP68, which can ensure the performance and safety of the control cabinet in special occasions (humid, dusty, etc.).

[0022] The cooling device can use the water inside the water tank to cool the cooling water in the cooling pipe 2. The cooling device can also use the fan of the cooling fin and fan cooling integrated device 6 to blow air on the cooling fins to dissipate heat from the cooling water. The cooling device can also use the natural low temperature of the underground constant temperature layer to circulate the cooling water to the underground pipe 7 for heat dissipation. For example, the average temperature in Shanghai in July is 27.8℃, 24.0℃ at 0.8 meters underground, 20.6℃ at 1.6 meters, and 16.9℃ at 3.2 meters. When the ground is hot, the natural low temperature of the constant temperature layer is more suitable for dissipating heat from the cooling water. Conversely, the average temperature in Shanghai in January is 3.4℃, 9.8℃ at 0.8 meters underground, 13.1℃ at 1.6 meters, and 17.3℃ at 3.2 meters.
